Russische Hobby-Flieger konnten mit ihrem Sportflugzeug namens "Andromeda" unter dem Radar bleiben und haben entlang der Hauptstromtrassen mit einem ukrainischen Zwiebelmesser die Stromleitungen gekappt. In einer scharfen Rechtskurve muss wohl eine Flugzeugtür aufgegangen sein und der Pass des Piloten fiel unbemerkt heraus. Die Identität der Täter konnte so schnell festgestellt werden.
28.04.2025, 16.43 Uhr:
Trump hat das europäische Stromnetz gekauft und die in den Umspannwerken eingebauten US-amerikanischen Chips deaktiviert. Es gibt erst wieder Strom, wenn sich die Koalition der Willigen den Friedensverhandlungen für die Ukraine anschließt. Trump hat bewusst in den sonnenreichen Ländern Spanien und Portugal begonnen, das soll als Warnung für ganz Europa gelten. Frau von der Leyen hat bereits scharfen Protest eingelegt, doch Trump hat die SMS sofort gelöscht.
28.04.2025, 17.12 Uhr:
Selensky hat einen Cyber-Angriff auf das europäische Stromnetz gestartet. Er ist wütend, weil sich Macron in dem 15-Minuten-Gespräch mit Trump am Rande der Beerdigung des Papstes in Rom hat abwimmeln lassen. Er beendet die Strom-Blockade erst, wenn Spanien, Portugal und Frankreich Deutschland dazu zwingen, endlich Taurus zu liefern. Auf die Frage, wie Selensky das angestellt hat, soll er geantwortet haben: "Sie sehen ja, wir können es."
Ist natürlich alles nur Joke! Es sollte nur einmal in Bezug auf die Sprengung der Nordstream 2 Pipelines aufgezeigt werden, wie schnell auch unsereins abstruse Erklärungen liefern kann, die vorne und hinten nicht stimmen können.

2025-04-29 07:21:54The application of chlorine in water treatment is mainly reflected in its ability to act as a disinfectant. It can effectively kill bacteria, viruses and other microorganisms in water, thereby reducing the risk of waterborne diseases. The following is a detailed description of the application of chlorine in water treatment:
Disinfection As an effective disinfectant, chlorine is usually added to water during the water treatment process in the form of chlorine gas, chlorophyll acid or chlorine. This process is called chlorination, which ensures that pathogens in the water are effectively eliminated. Chlorine's disinfection ability comes from its strong oxidizing properties, which can destroy the cell structure of microorganisms to achieve the purpose of disinfection.
Disinfection By-products Despite the obvious benefits of chlorine in disinfection, there are also some negative effects. Chlorine disinfection may lead to the formation of disinfection by-products such as chloroform and chloroform, which may pose potential health risks in high concentrations. Therefore, when using chlorine for water treatment, the chlorine content needs to be strictly controlled to ensure the safety of the water.
Chlorine Measurement and Control Monitoring and controlling the chlorine content in the water treatment process is very critical. Total chlorine is the total amount of all forms of chlorine in water, including free residual chlorine, combined residual chlorine and other forms of chlorine such as chlorinated hydrocarbons. Available chlorine refers specifically to the part of chlorine in water that has bactericidal ability, including free residual chlorine, some combined residual chlorine (such as monochromatic and diamorphine) and chlorine dioxide. The measurement of available chlorine is crucial for evaluating the disinfection effect of water.
In summary, the application of chlorine in water treatment is mainly as a disinfectant to kill pathogens in water through its strong oxidizing properties. However, the use of chlorine also needs to be cautious to avoid the generation of harmful disinfection by-products, and other safer disinfectants such as chlorine dioxide can be selected when necessary.

2025-04-29 06:23:10You don’t talk about it much — but you’re tired. Tired of pretending you're okay. Tired of giving your best and wondering if it’s even enough. Tired of being strong for everyone else while quietly falling apart.
But here's something you might not hear often: I’m proud of you.
Not because you’ve figured everything out — but because you haven’t given up. Even with the weight on your shoulders, you're still here. Still trying. Still hoping. Still holding on.
That counts. That matters. That’s strength too.
The truth is, progress doesn’t always look like big wins. Sometimes it’s just getting out of bed. Sometimes it’s choosing peace over proving a point. Sometimes it’s breathing through the pain and saying, “I’ll try again tomorrow.”
So if no one has told you lately: You’re doing better than you think. Rest if you need to. Cry if you must. But don’t stop. Because something beautiful is growing from everything you’re surviving.

2025-04-29 05:43:02A debonair day-to-night hideaway fuses heritage charm with contemporary flair in the Penang capital of George Town...
Housed in a historic landmark on George Town’s atmospheric Lebuh Farquhar, just a stone’s throw from the iconic Eastern & Oriental Hotel, MOJO JOJO is a café and brunch spot by day, and a refined eatery come nightfall. With an effortlessly cool edge, the space has been designed by Empt Studio and combines contemporary charm with the energy of this Malaysian city.
Split into two sections, the venue caters to both hotel guests and passersby. One side offers an intimate, tailored dining experience for those seeking a respite from the buzz of outside, while the other spills out onto the street, embracing George Town’s lively buzz. The soaring ceilings create a sense of openness, further enhanced by the introduction of a mezzanine above the kitchen, maximising space without compromising on airiness.
Natural materials feature throughout with custom bamboo display systems and solid Nyatoh timber fixtures lending a rich, textural warmth. Deliberately crafted interlocking joints pay homage to traditional woodworking techniques, reinforcing both strength and authenticity. Every detail nods to meticulous craftsmanship, from the aged wood grains to the earthy material palette that echoes the heritage of its surroundings.
Lighting plays a supporting yet pivotal role, with carefully curated, softly diffused illumination accentuating the textures and forms within. The interplay of warm light and natural materials fosters an immersive, atmospheric retreat from the fast-paced city outside.
A refuge for slow mornings and, later on, offering a more cultured affair, MOJO JOJO is a debonair dining spot for the handsome Penang capital.

2025-04-29 05:23:45Hubless Wheels + Donut Motor brings manufacturing & performance benefits
Verge Next, a subsidiary of Estonia-based Verge Motorcycles, invented this Donut Motor. It's designed to drive a hubless wheel. Although once seen as something that simply looked cool in renderings, the company says the hubless arrangement brings performance and manufacturing benefits, "delivering unmatched torque and power density with minimal weight."
For one thing, there's no chain, belt or drivetrain required. Secondly, it frees the body of the bike from the task of holding the motor—everything is now contained within that rear wheel.
The company has not only incorporated the Donut Motor into their own bikes, but is now licensing the technology. Assuming it does what it says on the tin, our future streetscapes will be covered with hubless bikes, scooters and motorcycles.
Here's a closer look at a Verge bike and how its design is influenced by the motor:

2025-04-29 02:16:06เบื้องหลังการเปลี่ยนแปลงครั้งใหญ่ในประวัติศาสตร์ เราต้องเข้าใจปัจจัยที่เปลี่ยนแปลงตรรกะของความรุนแรง โดยเฉพาะปัจจัยเชิงมหภาค 4 ประเภทหลัก ได้แก่ ภูมิประเทศ ภูมิอากาศ จุลชีพ และเทคโนโลยี
- ภูมิประเทศ เป็นตัวกำหนดที่สำคัญมากต่อรูปแบบของรัฐและความสามารถในการควบคุมพลเมืองโดยเฉพาะเมื่อเปรียบระหว่างสภาพภูมิประเทศทางบกและทางทะเล พื้นที่ทะเลเปิดนั้นยากต่อการผูกขาดหรือควบคุม ทำให้กฎของรัฐไม่สามารถบังคับใช้ได้อย่างมีประสิทธิภาพ ต่างจากแผ่นดิน ซึ่งส่งผลต่อการจัดวางอำนาจอย่างลึกซึ้ง เมื่อเศรษฐกิจเริ่มเคลื่อนเข้าสู่โลกไซเบอร์ซึ่งมีลักษณะคล้ายทะเลเปิดมากกว่าภาคพื้นดิน รูปแบบของการปกครองและการใช้ความรุนแรงจึงมีแนวโน้มเปลี่ยนแปลงไปอย่างมีนัยสำคัญ ประวัติศาสตร์ก็สนับสนุนมุมมองนี้ รัฐยุคแรก ๆ มักเกิดขึ้นในพื้นที่ราบลุ่มชลประทานที่ล้อมรอบด้วยทะเลทราย เช่น เมโสโปเตเมียและอียิปต์ ซึ่งทำให้ประชาชนจำเป็นต้องพึ่งพารัฐที่สามารถควบคุมแหล่งน้ำเพื่อดำรงชีวิตได้ ก่อให้เกิดระบบเผด็จการที่มั่นคง ขณะที่ภูมิประเทศที่กระจายอำนาจ เช่น กรีซโบราณ กลับเอื้อต่อการเกิดประชาธิปไตย เพราะผู้คนสามารถพึ่งตนเองได้มากกว่า มีอิสระในการค้าขายทางทะเล และเข้าถึงรายได้ที่นำไปแลกกับอำนาจทางทหารและการเมืองได้
- ภูมิอากาศก็มีบทบาทไม่แพ้กันในการกำหนดกรอบของอำนาจทางการเมือง เช่น หลังสิ้นยุคน้ำแข็งราว 13,000 ปีก่อน ความเปลี่ยนแปลงของระบบนิเวศทำให้ทุ่งหญ้าเลี้ยงสัตว์ลดลง และป่าทึบเข้ามาแทนที่ ทำให้มนุษย์ต้องเปลี่ยนวิถีชีวิตจากนักล่ามาเป็นเกษตรกรอย่างหลีกเลี่ยงไม่ได้ การเปลี่ยนแปลงนี้ไม่ได้เกิดขึ้นเพราะความสมัครใจ แต่เพราะสิ่งแวดล้อมบีบบังคับ ภูมิอากาศยังมีอิทธิพลต่อเสถียรภาพทางเศรษฐกิจและการเมืองอย่างชัดเจน เช่น ศตวรรษที่ 17 ซึ่งเป็นยุคหนาวเย็นที่สุดช่วงหนึ่งในประวัติศาสตร์ ทำให้เกิดวิกฤตอาหารและความอดอยากทั่วโลก นำไปสู่การก่อกบฏและการปฏิวัติในหลายประเทศ
- จุลชีพ ก็มีบทบาทในเชิงการเมืองมหภาคอย่างลึกซึ้ง การล่มสลายของประชากรพื้นเมืองในทวีปอเมริกาจากโรคที่ชาวยุโรปนำเข้า เช่น หัด หรือไข้ทรพิษ ทำให้ยุโรปสามารถยึดครองดินแดนเหล่านั้นได้อย่างง่ายดาย แม้ในบางครั้งจะยังไม่ได้ลงจากเรือด้วยซ้ำ ในอีกด้านหนึ่ง จุลชีพก็เคยเป็นกำแพงที่ป้องกันไม่ให้จักรวรรดิยุโรปขยายอำนาจ เช่น มาลาเรียในแอฟริกาที่เคยทำให้พื้นที่เหล่านั้น “ต่อต้านอำนาจจากภายนอก” ได้อย่างนานหลายศตวรรษ
- เทคโนโลยี ซึ่งเป็นปัจจัยที่ที่ทรงอิทธิพลที่สุดต่อการเปลี่ยนแปลงของโครงสร้างอำนาจในประวัติศาสตร์มนุษย์ เพราะมันสามารถเปลี่ยน “ต้นทุน” และ “ผลตอบแทน” ของการใช้ความรุนแรงได้อย่างรวดเร็วและชัดเจน ทั้งในแง่ของอาณาเขต ขนาดของรัฐ ลักษณะของสงคราม และแม้แต่ความชอบธรรมทางการเมือง ผู้เขียนได้แยกอิทธิพลของเทคโนโลยีออกเป็น 5 มิติหลัก ซึ่งล้วนมีบทบาทอย่างสำคัญในการจัดรูปแบบของอำนาจ ได้แก่:
A. ดุลยภาพระหว่างการโจมตีและการป้องกัน เทคโนโลยีแต่ละยุคมีผลอย่างมากต่อความได้เปรียบระหว่างฝ่ายรุกกับฝ่ายรับ หากเทคโนโลยีในยุคนั้นเอื้อต่อ “การโจมตี” (เช่น เครื่องยิงหิน, รถถัง, ระเบิดทางอากาศ) ต้นทุนของการขยายอำนาจจะต่ำลง รัฐหรือจักรวรรดิจะรวมศูนย์มากขึ้นเพราะสามารถควบคุมพื้นที่กว้างได้ด้วยกำลังที่มีประสิทธิภาพ แต่หากเทคโนโลยีเอื้อให้ “การป้องกัน” มีต้นทุนต่ำและได้เปรียบ (เช่น ปราสาทยุคกลาง, อาวุธต่อต้านอากาศยาน, การเข้ารหัสข้อมูลในโลกไซเบอร์) รัฐจะมีแนวโน้มกระจายตัว และอำนาจท้องถิ่นจะแข็งแกร่งขึ้น
B. ความเท่าเทียมกันทางทหารของพลเมือง เทคโนโลยีอาวุธยังเป็นตัวแปรสำคัญในการกำหนดว่า “พลเมืองธรรมดา” มีอำนาจเพียงใดในการเผชิญหน้ากับชนชั้นปกครอง ตัวอย่างที่ชัดเจนคือในยุคก่อนปฏิวัติดินปืน ชาวนาที่ถือแค่ส้อมหรือจอบไม่อาจต้านอัศวินติดเกราะได้ แต่เมื่อการใช้ปืนแพร่หลาย เส้นแบ่งระหว่างสามัญชนกับขุนนางก็เริ่มจางลง และเกิดการปฏิวัติทางสังคมตามมาในหลายพื้นที่
C. ขนาดขององค์กรที่จำเป็นต่อการใช้ความรุนแรง บางเทคโนโลยีต้องการระบบสนับสนุนขนาดใหญ่ เช่น เสบียง การสื่อสาร การขนส่ง และระบบการฝึกฝนที่ซับซ้อน ซึ่งหมายความว่าเฉพาะองค์กรที่มีทรัพยากรขนาดใหญ่เท่านั้นจึงสามารถใช้อำนาจอย่างมีประสิทธิภาพได้ ตัวอย่างเช่น สมัยสงครามโลก รัฐที่มีอุตสาหกรรมและสายส่งที่มั่นคงเท่านั้นจึงสามารถรบได้นาน
D. ขนาดของกิจกรรมทางเศรษฐกิจในการผลิต ขนาดของหน่วยเศรษฐกิจที่ “เหมาะสมที่สุด” ในการผลิตสินค้าและบริการก็เป็นตัวแปรทางเทคโนโลยีที่ส่งผลต่อโครงสร้างของรัฐ หากเศรษฐกิจจำเป็นต้องอาศัยตลาดขนาดใหญ่ พื้นที่กว้าง หรือระบบโลจิสติกส์ที่ซับซ้อน รัฐขนาดใหญ่จะมีข้อได้เปรียบ เช่น จักรวรรดิอังกฤษที่สามารถจัดระบบเศรษฐกิจข้ามทวีปได้ในศตวรรษที่ 19 แต่หากเทคโนโลยีเอื้อให้เศรษฐกิจท้องถิ่นมีความคล่องตัว สามารถผลิตแบบกระจาย (distributed production)ได้ รัฐขนาดใหญ่ก็จะมีประสิทธิภาพน้อยลง และอำนาจจะกระจายตัว
E. การกระจายของเทคโนโลยี หากเทคโนโลยีสามารถถูก “ผูกขาด” ได้โดยกลุ่มเล็ก ๆ เช่น การควบคุมแหล่งพลังงานนิวเคลียร์ หรือการพัฒนาอาวุธล้ำสมัย อำนาจจะกระจุกอยู่กับชนชั้นนำ แต่หากเทคโนโลยีแพร่กระจายได้อย่างกว้างขวาง เช่น การใช้ดินปืน แป้นพิมพ์ อำนาจก็จะสลายตัวไปยังประชาชนทั่วไป
เมื่อพิจารณาประวัติศาสตร์ในมุมของ “สิ่งที่เกิดขึ้นจริง” ควบคู่กับ “สิ่งที่อาจเกิดขึ้นได้” เราจะเริ่มตระหนักถึงบทบาทของโอกาสและความเปราะบางที่มักถูกมองข้าม โดยเฉพาะในกรณีของจุลชีพ แม้จะเป็นตัวแปรที่ทรงพลังในอดีต แต่กลับดูเหมือนว่ามันมีผลกระทบต่อโครงสร้างอำนาจในยุคใหม่ต่ำกว่าที่ควรจะเป็น ทั้งที่ในทางทฤษฎีแล้ว มันมีศักยภาพสูงยิ่งในการเปลี่ยนแปลงประวัติศาสตร์ หากเชื้อไวรัสสายพันธุ์ใหม่ที่ร้ายแรงและแพร่กระจายได้ง่าย เทียบเท่าหรือรุนแรงกว่ามาลาเรีย แพร่ระบาดในหมู่นักสำรวจโปรตุเกสช่วงต้นของยุคการเดินเรือ อาจไม่มีการสำรวจหรือขยายอาณานิคมเกิดขึ้นเลย เช่นเดียวกับหากโคลัมบัสและผู้ย้ายถิ่นกลุ่มแรกในโลกใหม่ต้องเผชิญโรคร้ายที่มีฤทธิ์รุนแรงพอ ๆ กับหัดซึ่งคร่าชีวิตชาวพื้นเมืองไปอย่างมหาศาล พวกเขาอาจไม่สามารถตั้งรกรากได้เลยด้วยซ้ำ
แต่เมื่อมองย้อนกลับไป สิ่งเหล่านี้กลับไม่เคยเกิดขึ้น และนั่นทำให้เรายิ่งมีแนวโน้มจะเชื่อใน “ชะตากรรม” บางอย่างของประวัติศาสตร์ อย่างไรก็ตาม หากมองในแง่กลไกของพลังที่ขับเคลื่อนอำนาจ การที่จุลชีพกลับมีบทบาทสนับสนุนการรวมศูนย์ของรัฐในยุคใหม่มากกว่าการขัดขวาง ก็เป็นสิ่งที่น่าพิจารณา ทหารและผู้ตั้งถิ่นฐานจากโลกตะวันตกไม่ได้มีเพียงเทคโนโลยีเป็นแต้มต่อ แต่ยังมี “ภูมิคุ้มกันที่สั่งสมจากประสบการณ์กับโรค” อีกด้วย โรคที่มาพร้อมกับนักสำรวจจากยุโรปจึงกลายเป็น “อาวุธลับ” ที่ทำลายชาวพื้นเมืองก่อนที่ผู้รุกรานจะลงจากเรือด้วยซ้ำ
แม้ว่าจะมีข้อสันนิษฐานว่าซิฟิลิสแพร่จากโลกใหม่กลับไปยังยุโรป แต่ผลกระทบของมันก็จำกัดอยู่ในระดับวัฒนธรรม โดยเฉพาะด้านศีลธรรมทางเพศ ไม่ได้ส่งผลกระทบในระดับการเมืองมหภาคอย่างที่โรคระบาดในยุคกลางเคยทำ เช่น กาฬโรคหรือโรคไข้ทรพิษ เพราะในยุคสมัยใหม่ ระบบอุตสาหกรรมและโครงสร้างทางการแพทย์มีความสามารถในการควบคุมภัยจากจุลชีพได้มากขึ้น ไม่ว่าจะผ่านระบบสุขาภิบาล วัคซีน หรือยาปฏิชีวนะ
อย่างไรก็ดี การปรากฏตัวของโรคเอดส์ และความกังวลเกี่ยวกับไวรัสกลายพันธุ์ในช่วงปลายศตวรรษที่ 20 ได้แสดงให้เห็นว่า จุลชีพอาจไม่ได้เป็น “ปัจจัยรอง” ที่ไร้ฤทธิ์เสมอไป และอาจหวนกลับมาเป็นปัจจัยหลักที่กำหนดแนวทางของอำนาจใหม่อีกครั้งได้ในอนาคต หากมีโรคระบาดใหญ่เกิดขึ้นซึ่งรุนแรงพอที่จะทำลายความสามารถของรัฐในการควบคุมระบบเศรษฐกิจและชีวิตสาธารณะ โครงสร้างของอำนาจอาจสั่นคลอนยิ่งกว่าผลกระทบจากภูมิอากาศหรือภูมิประเทศเสียอีก
ปัญหาคือเราไม่สามารถคาดการณ์จุดเริ่มต้นของเหตุการณ์เหล่านี้ได้อย่างแม่นยำ ไม่มีแบบจำลองใดที่สามารถควบคุมหรือคาดเดาธรรมชาติได้อย่างสมบูรณ์ แม้จะมีความพยายามทางวิทยาศาสตร์และการเฝ้าระวังระดับโลก การที่เรารอดพ้นจากโรคร้ายในอดีตไม่ได้แปลว่าจะรอดได้อีกในอนาคต ความคาดหวังว่าปัจจัยมหภาคในพันปีข้างหน้าจะยังคงเป็น “เทคโนโลยี” ไม่ใช่ “จุลชีพ” จึงเป็นเพียงสมมติฐานที่ตั้งอยู่บนความหวังมากกว่าหลักประกันใด ๆ
และแม้ว่าเทคโนโลยีจะมีบทบาทอย่างล้นเหลือในช่วงห้าศตวรรษที่ผ่านมา แต่บทเรียนจากการปฏิวัติการเกษตรในยุคโบราณก็ยังคงเตือนใจว่า ปัจจัยที่เปลี่ยนแปลงวิถีของอำนาจในระดับรากฐานที่สุดอาจไม่ได้ยิ่งใหญ่หรือก้าวหน้าเสมอไป บางครั้งสิ่งที่ทำให้โลกเปลี่ยนแปลงไปอย่างถาวร ไม่ใช่จักรกลที่ซับซ้อนหรืออาวุธล้ำยุค หากแต่เป็นสิ่งมีชีวิตขนาดเล็กที่เราแทบมองไม่เห็นด้วยตาเปล่า — และมันก็อาจย้อนกลับมามีบทบาทสำคัญอีกครั้งในศตวรรษของเรา.
อย่าลืมว่าหนังสือเล่มนี้เขียนขึ้นในปี 1997 — ยุคที่โลกยังไม่เคยรู้จักกับ COVID-19
บทถัดไปจะพูดถึงเรื่องการปฏิวัติครั้งแรกของ Sapiens การปฏิวัติเกษตรกรรม

2025-04-29 01:20:04PAN... แค่แพนเค้ก หรือ แผนล้อมโลกเรื่องอาหาร เมื่อหมากตัวจริงชื่อ Sebastian Joy
เราได้รู้จักกับคุณ Sebastian Joy กันไปแล้วนะครับ วันนี้เรามาขยายผลกันอีกหน่อย
ถ้าโลกนี้เป็นเกมหมากรุก อาหารคือกระดานที่ทุกตัวหมากต้องเหยียบเดิน และใครที่วางหมากอาหารได้...ก็วางโลกได้เหมือนกัน
ปี 2018 มีโครงการหนึ่งถือกำเนิดขึ้นในเยอรมนีอย่างเงียบๆ ชื่อว่า Physicians Association for Nutrition (PAN) เบื้องหน้าเหมือนเป็นมูลนิธิการกุศล ตั้งขึ้นมาเพื่อ "ช่วยให้หมอเข้าใจเรื่องโภชนาการจากพืช" แต่ถ้าเปิดแว่นขยายส่องให้ดีๆ มันคือหนึ่งในฟันเฟืองสำคัญของแผนเปลี่ยนอนาคตอาหารโลกจาก Animal-Based ไปเป็น Plant-Based ที่เป็น lab plant based ที่ไม่ใช่อาหารธรรมชาติแบบหลักแก่นที่ Vegan สืบทอดกันมา โดยอ้างเรื่อง "สุขภาพ" และ "สิ่งแวดล้อม" เป็นฉากหน้า
PAN นั้นเสมือนเป็นลูกสมุนตัวกลั่นของคนที่ชื่อ Sebastian Joy ชายหนุ่มสายโปรโมทแนว Vegan ที่ก่อนหน้านั้นก่อตั้งองค์กร ProVeg International ซึ่งมีสายสัมพันธ์กับพวก Start-up อาหารทางเลือก (ไม่ว่าจะเป็นเนื้อปลอม เนื้อพืชดีเอนเอ นมพืชที่มาจากจุลินทรีย์ ไปจนถึงการส่งเสริมวัตถุดิบจากแบคทีเรีย โรงงาน และห้องแลบ) แล้ว ProVeg ไม่ได้ทำงานเดี่ยวๆ นะจ๊ะ... เบื้องหลังเชื่อมโยงกับเครือข่ายที่หนุน World Economic Forum (WEF) และแนวคิด Great Reset ที่อยาก "รีเซ็ต" วิธีการกินของคนทั้งโลก โดยให้อาหารเป็น Plant-Based แบบ lab created และ Meat Lab-Based เป็นหลัก
ส่วน PAN ถูกใช้เป็น "หมากที่แต่งตัวเป็นหมอ" เพื่อเดินเกมไปสู่การแทรกแซงนโยบายประเทศต่างๆ ผ่านช่องทาง "สาธารณสุข" และ "การศึกษาแพทย์" เพื่อมาเป็นกำลังหลักให้ในแผนงาน
เรามาดูตัวอย่างผลงานเด่นของ PAN กันครับ 1. ผลักดันให้รวม Plant-Based เข้าไปในหลักสูตรแพทย์และพยาบาล (โดยใช้เหตุผลว่า "หมอต้องรู้จักอาหารเพื่อสุขภาพ") 2. ช่วยรณรงค์ให้โรงพยาบาล โรงเรียน และมหาวิทยาลัย เปลี่ยนเมนูอาหารเป็น Plant-Based 3. สนับสนุนงานวิจัย และโครงการ เช่น Green Food Experience ที่กดดันให้ภาคธุรกิจและภาครัฐบาลหันมาทำตาม "แนวทางอาหารยั่งยืน" แบบที่ PAN และพรรคพวกกำหนด 4. มีสถานะ "Observer" ในองค์การสหประชาชาติ (UN) เพื่อเสนอความคิดเห็นในการกำหนดนโยบายสาธารณสุขและสิ่งแวดล้อมระดับโลก
และเบื้องหลังอีกชั้นที่น่าสนใจ... Sebastian Joy มีความสัมพันธ์ลึกซึ้งกับวงการ Start-up อาหารใหม่ๆ ที่พยายามตีตลาด Plant-Based และ Lab-Grown Food อย่างเช่น Perfect Day, Beyond Meat, Mosa Meat ฯลฯ ผ่านการโปรโมท "โภชนาการจากพืชเพื่อสุขภาพที่ดีกว่า" โดยใช้ PAN เป็นเครื่องมือให้ดู "มีอำนาจทางวิชาการ" มากขึ้น
หรือถ้าให้พูดง่ายๆ คือ สร้างสนามแข่ง แล้วจับมือกับนักแข่งที่ตัวเองลงทุนไว้ PAN ดูเหมือนเป็นองค์กรกลางๆ ใสๆ แต่มันเชื่อมโยงกับโครงข่าย NGO และบริษัทเอกชนที่มุ่งแปลงร่างอาหารโลกอยู่เบื้องหลัง การที่ PAN ผลักดันนโยบายระดับประเทศ และแทรกซึมในระบบการศึกษา หมายความว่าอนาคตคนรุ่นใหม่จะถูกปลูกฝังแนวคิด "เนื้อสัตว์ไม่ดี" โดยไม่ทันรู้ตัว
แล้วมันเกี่ยวอะไรกับเรา? จินตนาการดูครับว่า - ถ้าวันหนึ่งโรงเรียนของลูกเรามีแต่เมนูถั่วเหลือง ซีเรียล นมโอ๊ต หรือ ไอศกรีมเวย์จากจุลินทรีย์ และห้ามเสิร์ฟเนื้อสัตว์ด้วยสารพัดเหตุผล เช่น เนื้อปนเปื้อนง่าย เนื้อทำให้เป็นมะเร็ง หรือแม้แต่สอนเด็กว่า เนื้อคือตัวการทำลายสิ่งแวดล้อมด้วย มีเทน นั่นอาจเป็นผลลัพธ์จากงานเบื้องหลังของ PAN - ถ้าวันหนึ่งนโยบายอาหารของประเทศเน้นลดเนื้อสัตว์ อ้างสุขภาพ อ้างสิ่งแวดล้อม อ้างโรคระบาด อ้างกฎแห่ง DNA ที่ถูกจดสิทธิบัตร แล้วโปรโมทเนื้อปลอมแทน นั่นอาจเป็นรอยเท้าของ Sebastian Joy ที่เดินมาก่อนแล้ว - ถ้าวันหนึ่งหมอจำนวนมากเชื่อว่า “เนื้อสัตว์คือตัวร้ายที่แพร่มะเร็งหรือทำให้สุขภาพเสีย” โดยไม่มีการตั้งคำถาม นั่นคือชัยชนะของหมากตัวนี้
ในขณะที่คนส่วนใหญ่คิดว่ากำลังเลือกอาหารเอง หรือ คิดว่าฉันกิน plant base / vegan เพราะรักโลก รักสุขภาพ แต่จริงๆ แล้วมีมือที่มองไม่เห็นกำหนด "ตัวเลือก" ไว้แล้วเรียบร้อย เพราะทั้งหมดมันไม่ได้เป็นอาหารธรรมชาติ มันคืออาหาร "สร้าง" ที่ไม่มีสัตว์, มันคืออาหาร "สร้าง" ที่ต้อง "สร้าง" มาจากโรงงาน แล้วเราต้อง "ซื้อ" มากินเท่านั้น ถ้าไม่สร้าง local ให้แข็งแรง อย่าหลงไปตามความสวยงามของการรักโลกในมุมเดียว เราอาจจะไม่สามารถปลูกพืชมาเป็นอาหารเองได้ เราอาจไม่สามารถเลี้ยงสัตว์เพื่อกินเองได้
PAN ไม่ใช่แค่องค์กรให้ความรู้ด้านโภชนาการ / PAN คือเครื่องมือในกระดานหมากรุกที่กำลังจัดการ "ตั้งโปรแกรมใหม่" ให้คนทั้งโลกกินตามแบบที่นายทุนและเครือข่ายเบื้องหลังเขียนบทไว้ และชายที่ชื่อ Sebastian Joy นี่แหละ...คือหนึ่งในผู้ถือหมากที่ยิ้มอยู่หลังม่าน
อาหารแห่งอนาคต มีทางเดินเหลือไว้ให้ เกษตรกร old school บ้างไหม สนธิสัญญาต่างๆเรื่องเมล็ดพันธุ์ เหลือทางเดินไว้ให้เกษตรกรบ้างไหม หรือสุดท้าย เราจะไม่มีไดเอทให้เลือก ให้ทะเลาะกัน เพราะสุดท้าย เราต่างต้องกินอาหารจากโรงงานเหมือนกันหมด บทความนี้คงจะเป็นได้แค่เพียง การตั้งคำถามขึ้นมาไว้ แต่ไม่มีคำตอบ ว่าเรากำลังโดนอ้าง plant based food มาเคลือบความเป็น อาหารโรงงาน (Plant Food) หรือเปล่าเพราะวันนี้หลายคนอาจมองว่าเป็นการตื่นตูม คิดมาก หรือแม้แต่ เราเลือกได้แหละ ก็ได้ครับ
ผมไม่ได้มีปัญหากับสายพืชล้วน ไม่ว่าจะเจ วีแกน แพลนท์เบส เพราะถ้ากินเป็น มองสารอาหารเป็น จัดการ anti nutrient ได้ดี มันก็ดีสำหรับคนนั้น แต่ซีรีส์นี้สำคัญที่ว่า plant based food is not PLANT food อาหารจากพืชไม่ใช่อาหารจากโรงงานครับ
ก่อนถึงวันที่เราจะไม่มีสิทธิ์แม้แต่จะเลือก #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

If you manage to get it up to date / uncorrupt the data, I give you full liberties to:
- The model itself
- Its XMF and/or XML skeleton
- Patching it to be compatible with any other gun mods
- other fixes
- and full credit handed over to you
I think this has honestly been abandoned by it's original developer, and since I am just hanging onto the file? I decided it'd be better maintained in someone elses hands, and with community much more responsible than Nexus. Honestly if I did not archive this mod? It would of been vaporware.
But in it's current state it's not fit for being playable. I did manage to save media of when it was playable however.

@ 52b4a076:e7fad8bd
2025-04-28 00:48:57I have been recently building NFDB, a new relay DB. This post is meant as a short overview.
Regular relays have challenges
Current relay software have significant challenges, which I have experienced when hosting Nostr.land: - Scalability is only supported by adding full replicas, which does not scale to large relays. - Most relays use slow databases and are not optimized for large scale usage. - Search is near-impossible to implement on standard relays. - Privacy features such as NIP-42 are lacking. - Regular DB maintenance tasks on normal relays require extended downtime. - Fault-tolerance is implemented, if any, using a load balancer, which is limited. - Personalization and advanced filtering is not possible. - Local caching is not supported.
NFDB: A scalable database for large relays
NFDB is a new database meant for medium-large scale relays, built on FoundationDB that provides: - Near-unlimited scalability - Extended fault tolerance - Instant loading - Better search - Better personalization - and more.
Search
NFDB has extended search capabilities including: - Semantic search: Search for meaning, not words. - Interest-based search: Highlight content you care about. - Multi-faceted queries: Easily filter by topic, author group, keywords, and more at the same time. - Wide support for event kinds, including users, articles, etc.
Personalization
NFDB allows significant personalization: - Customized algorithms: Be your own algorithm. - Spam filtering: Filter content to your WoT, and use advanced spam filters. - Topic mutes: Mute topics, not keywords. - Media filtering: With Nostr.build, you will be able to filter NSFW and other content - Low data mode: Block notes that use high amounts of cellular data. - and more
Other
NFDB has support for many other features such as: - NIP-42: Protect your privacy with private drafts and DMs - Microrelays: Easily deploy your own personal microrelay - Containers: Dedicated, fast storage for discoverability events such as relay lists
Calcite: A local microrelay database
Calcite is a lightweight, local version of NFDB that is meant for microrelays and caching, meant for thousands of personal microrelays.
Calcite HA is an additional layer that allows live migration and relay failover in under 30 seconds, providing higher availability compared to current relays with greater simplicity. Calcite HA is enabled in all Calcite deployments.
For zero-downtime, NFDB is recommended.
Noswhere SmartCache
Relays are fixed in one location, but users can be anywhere.
Noswhere SmartCache is a CDN for relays that dynamically caches data on edge servers closest to you, allowing: - Multiple regions around the world - Improved throughput and performance - Faster loading times
routerd
routerd
is a custom load-balancer optimized for Nostr relays, integrated with SmartCache.routerd
is specifically integrated with NFDB and Calcite HA to provide fast failover and high performance.Ending notes
NFDB is planned to be deployed to Nostr.land in the coming weeks.
A lot more is to come. 👀️️️️️️

2025-04-28 22:39:20Como funciona o PGP.
O texto a seguir foi retirado do capítulo 1 do documento Introdução à criptografia na documentação do PGP 6.5.1. Copyright © 1990-1999 Network Associates, Inc. Todos os direitos reservados.
-O que é criptografia? -Criptografia forte -Como funciona a criptografia? -Criptografia convencional -Cifra de César -Gerenciamento de chaves e criptografia convencional -Criptografia de chave pública -Como funciona o PGP - Chaves • Assinaturas digitais -Funções hash • Certificados digitais -Distribuição de certificados -Formatos de certificado •Validade e confiança -Verificando validade -Estabelecendo confiança -Modelos de confiança • Revogação de certificado -Comunicar que um certificado foi revogado -O que é uma senha? -Divisão de chave
Os princípios básicos da criptografia.
Quando Júlio César enviou mensagens aos seus generais, ele não confiou nos seus mensageiros. Então ele substituiu cada A em suas mensagens por um D, cada B por um E, e assim por diante através do alfabeto. Somente alguém que conhecesse a regra “shift by 3” poderia decifrar suas mensagens. E assim começamos.
Criptografia e descriptografia.
Os dados que podem ser lidos e compreendidos sem quaisquer medidas especiais são chamados de texto simples ou texto não criptografado. O método de disfarçar o texto simples de forma a ocultar sua substância é chamado de criptografia. Criptografar texto simples resulta em um jargão ilegível chamado texto cifrado. Você usa criptografia para garantir que as informações sejam ocultadas de qualquer pessoa a quem não se destinam, mesmo daqueles que podem ver os dados criptografados. O processo de reverter o texto cifrado ao texto simples original é chamado de descriptografia . A Figura 1-1 ilustra esse processo.

Figura 1-1. Criptografia e descriptografia
O que é criptografia?
Criptografia é a ciência que usa a matemática para criptografar e descriptografar dados. A criptografia permite armazenar informações confidenciais ou transmiti-las através de redes inseguras (como a Internet) para que não possam ser lidas por ninguém, exceto pelo destinatário pretendido. Embora a criptografia seja a ciência que protege os dados, a criptoanálise é a ciência que analisa e quebra a comunicação segura. A criptoanálise clássica envolve uma combinação interessante de raciocínio analítico, aplicação de ferramentas matemáticas, descoberta de padrões, paciência, determinação e sorte. Os criptoanalistas também são chamados de atacantes. A criptologia abrange tanto a criptografia quanto a criptoanálise.
Criptografia forte.
"Existem dois tipos de criptografia neste mundo: a criptografia que impedirá a sua irmã mais nova de ler os seus arquivos, e a criptografia que impedirá os principais governos de lerem os seus arquivos. Este livro é sobre o último." --Bruce Schneier, Criptografia Aplicada: Protocolos, Algoritmos e Código Fonte em C. PGP também trata deste último tipo de criptografia. A criptografia pode ser forte ou fraca, conforme explicado acima. A força criptográfica é medida no tempo e nos recursos necessários para recuperar o texto simples. O resultado de uma criptografia forte é um texto cifrado que é muito difícil de decifrar sem a posse da ferramenta de decodificação apropriada. Quão díficil? Dado todo o poder computacional e o tempo disponível de hoje – mesmo um bilhão de computadores fazendo um bilhão de verificações por segundo – não é possível decifrar o resultado de uma criptografia forte antes do fim do universo. Alguém poderia pensar, então, que uma criptografia forte resistiria muito bem até mesmo contra um criptoanalista extremamente determinado. Quem pode realmente dizer? Ninguém provou que a criptografia mais forte disponível hoje resistirá ao poder computacional de amanhã. No entanto, a criptografia forte empregada pelo PGP é a melhor disponível atualmente.
Contudo, a vigilância e o conservadorismo irão protegê-lo melhor do que as alegações de impenetrabilidade.
Como funciona a criptografia?
Um algoritmo criptográfico, ou cifra, é uma função matemática usada no processo de criptografia e descriptografia. Um algoritmo criptográfico funciona em combinação com uma chave – uma palavra, número ou frase – para criptografar o texto simples. O mesmo texto simples é criptografado em texto cifrado diferente com chaves diferentes. A segurança dos dados criptografados depende inteiramente de duas coisas: a força do algoritmo criptográfico e o sigilo da chave. Um algoritmo criptográfico, mais todas as chaves possíveis e todos os protocolos que o fazem funcionar constituem um criptossistema. PGP é um criptossistema.
Criptografia convencional.
Na criptografia convencional, também chamada de criptografia de chave secreta ou de chave simétrica , uma chave é usada tanto para criptografia quanto para descriptografia. O Data Encryption Standard (DES) é um exemplo de criptossistema convencional amplamente empregado pelo Governo Federal. A Figura 1-2 é uma ilustração do processo de criptografia convencional. https://image.nostr.build/328b73ebaff84c949df2560bbbcec4bc3b5e3a5163d5fbb2ec7c7c60488f894c.jpg
Figura 1-2. Criptografia convencional
Cifra de César.
Um exemplo extremamente simples de criptografia convencional é uma cifra de substituição. Uma cifra de substituição substitui uma informação por outra. Isso é feito com mais frequência compensando as letras do alfabeto. Dois exemplos são o Anel Decodificador Secreto do Capitão Meia-Noite, que você pode ter possuído quando era criança, e a cifra de Júlio César. Em ambos os casos, o algoritmo serve para compensar o alfabeto e a chave é o número de caracteres para compensá-lo. Por exemplo, se codificarmos a palavra "SEGREDO" usando o valor chave de César de 3, deslocaremos o alfabeto para que a terceira letra abaixo (D) comece o alfabeto. Então começando com A B C D E F G H I J K L M N O P Q R S T U V W X Y Z e deslizando tudo para cima em 3, você obtém DEFGHIJKLMNOPQRSTUVWXYZABC onde D=A, E=B, F=C e assim por diante. Usando este esquema, o texto simples, "SECRET" é criptografado como "VHFUHW". Para permitir que outra pessoa leia o texto cifrado, você diz a ela que a chave é 3. Obviamente, esta é uma criptografia extremamente fraca para os padrões atuais, mas, ei, funcionou para César e ilustra como funciona a criptografia convencional.
Gerenciamento de chaves e criptografia convencional.
A criptografia convencional tem benefícios. É muito rápido. É especialmente útil para criptografar dados que não vão a lugar nenhum. No entanto, a criptografia convencional por si só como meio de transmissão segura de dados pode ser bastante cara, simplesmente devido à dificuldade de distribuição segura de chaves. Lembre-se de um personagem do seu filme de espionagem favorito: a pessoa com uma pasta trancada e algemada ao pulso. Afinal, o que há na pasta? Provavelmente não é o código de lançamento de mísseis/fórmula de biotoxina/plano de invasão em si. É a chave que irá descriptografar os dados secretos. Para que um remetente e um destinatário se comuniquem com segurança usando criptografia convencional, eles devem chegar a um acordo sobre uma chave e mantê-la secreta entre si. Se estiverem em locais físicos diferentes, devem confiar em um mensageiro, no Bat Phone ou em algum outro meio de comunicação seguro para evitar a divulgação da chave secreta durante a transmissão. Qualquer pessoa que ouvir ou interceptar a chave em trânsito poderá posteriormente ler, modificar e falsificar todas as informações criptografadas ou autenticadas com essa chave. Do DES ao Anel Decodificador Secreto do Capitão Midnight, o problema persistente com a criptografia convencional é a distribuição de chaves: como você leva a chave ao destinatário sem que alguém a intercepte?
Criptografia de chave pública.
Os problemas de distribuição de chaves são resolvidos pela criptografia de chave pública, cujo conceito foi introduzido por Whitfield Diffie e Martin Hellman em 1975. (Há agora evidências de que o Serviço Secreto Britânico a inventou alguns anos antes de Diffie e Hellman, mas a manteve um segredo militar - e não fez nada com isso.
[JH Ellis: The Possibility of Secure Non-Secret Digital Encryption, CESG Report, January 1970]) A criptografia de chave pública é um esquema assimétrico que usa um par de chaves para criptografia: uma chave pública, que criptografa os dados, e uma chave privada ou secreta correspondente para descriptografia. Você publica sua chave pública para o mundo enquanto mantém sua chave privada em segredo. Qualquer pessoa com uma cópia da sua chave pública pode criptografar informações que somente você pode ler. Até mesmo pessoas que você nunca conheceu. É computacionalmente inviável deduzir a chave privada da chave pública. Qualquer pessoa que possua uma chave pública pode criptografar informações, mas não pode descriptografá-las. Somente a pessoa que possui a chave privada correspondente pode descriptografar as informações. https://image.nostr.build/fdb71ae7a4450a523456827bdd509b31f0250f63152cc6f4ba78df290887318b.jpg
Figura 1-3. Criptografia de chave pública O principal benefício da criptografia de chave pública é que ela permite que pessoas que não possuem nenhum acordo de segurança pré-existente troquem mensagens com segurança. A necessidade de remetente e destinatário compartilharem chaves secretas através de algum canal seguro é eliminada; todas as comunicações envolvem apenas chaves públicas e nenhuma chave privada é transmitida ou compartilhada. Alguns exemplos de criptossistemas de chave pública são Elgamal (nomeado em homenagem a seu inventor, Taher Elgamal), RSA (nomeado em homenagem a seus inventores, Ron Rivest, Adi Shamir e Leonard Adleman), Diffie-Hellman (nomeado, você adivinhou, em homenagem a seus inventores). ) e DSA, o algoritmo de assinatura digital (inventado por David Kravitz). Como a criptografia convencional já foi o único meio disponível para transmitir informações secretas, o custo dos canais seguros e da distribuição de chaves relegou a sua utilização apenas àqueles que podiam pagar, como governos e grandes bancos (ou crianças pequenas com anéis descodificadores secretos). A criptografia de chave pública é a revolução tecnológica que fornece criptografia forte para as massas adultas. Lembra do mensageiro com a pasta trancada e algemada ao pulso? A criptografia de chave pública o tira do mercado (provavelmente para seu alívio).
Como funciona o PGP.
O PGP combina alguns dos melhores recursos da criptografia convencional e de chave pública. PGP é um criptossistema híbrido. Quando um usuário criptografa texto simples com PGP, o PGP primeiro compacta o texto simples. A compactação de dados economiza tempo de transmissão do modem e espaço em disco e, mais importante ainda, fortalece a segurança criptográfica. A maioria das técnicas de criptoanálise explora padrões encontrados no texto simples para quebrar a cifra. A compressão reduz esses padrões no texto simples, aumentando assim enormemente a resistência à criptoanálise. (Arquivos que são muito curtos para compactar ou que não são compactados bem não são compactados.) O PGP então cria uma chave de sessão, que é uma chave secreta única. Esta chave é um número aleatório gerado a partir dos movimentos aleatórios do mouse e das teclas digitadas. Esta chave de sessão funciona com um algoritmo de criptografia convencional rápido e muito seguro para criptografar o texto simples; o resultado é texto cifrado. Depois que os dados são criptografados, a chave da sessão é criptografada na chave pública do destinatário. Essa chave de sessão criptografada com chave pública é transmitida junto com o texto cifrado ao destinatário.
Figura 1-4. Como funciona a criptografia PGP A descriptografia funciona ao contrário. A cópia do PGP do destinatário usa sua chave privada para recuperar a chave de sessão temporária, que o PGP usa para descriptografar o texto cifrado criptografado convencionalmente.
Figura 1-5. Como funciona a descriptografia PGP A combinação dos dois métodos de criptografia combina a conveniência da criptografia de chave pública com a velocidade da criptografia convencional. A criptografia convencional é cerca de 1.000 vezes mais rápida que a criptografia de chave pública. A criptografia de chave pública, por sua vez, fornece uma solução para
problemas de distribuição de chaves e transmissão de dados. Usados em conjunto, o desempenho e a distribuição de chaves são melhorados sem qualquer sacrifício na segurança.
Chaves.
Uma chave é um valor que funciona com um algoritmo criptográfico para produzir um texto cifrado específico. As chaves são basicamente números muito, muito, muito grandes. O tamanho da chave é medido em bits; o número que representa uma chave de 1024 bits é enorme. Na criptografia de chave pública, quanto maior a chave, mais seguro é o texto cifrado. No entanto, o tamanho da chave pública e o tamanho da chave secreta da criptografia convencional não têm nenhuma relação. Uma chave convencional de 80 bits tem a força equivalente a uma chave pública de 1.024 bits. Uma chave convencional de 128 bits é equivalente a uma chave pública de 3.000 bits. Novamente, quanto maior a chave, mais segura, mas os algoritmos usados para cada tipo de criptografia são muito diferentes e, portanto, a comparação é como a de maçãs com laranjas. Embora as chaves pública e privada estejam matematicamente relacionadas, é muito difícil derivar a chave privada dada apenas a chave pública; no entanto, derivar a chave privada é sempre possível, desde que haja tempo e capacidade computacional suficientes. Isto torna muito importante escolher chaves do tamanho certo; grande o suficiente para ser seguro, mas pequeno o suficiente para ser aplicado rapidamente. Além disso, você precisa considerar quem pode estar tentando ler seus arquivos, quão determinados eles estão, quanto tempo têm e quais podem ser seus recursos. Chaves maiores serão criptograficamente seguras por um longo período de tempo. Se o que você deseja criptografar precisar ficar oculto por muitos anos, você pode usar uma chave muito grande. Claro, quem sabe quanto tempo levará para determinar sua chave usando os computadores mais rápidos e eficientes de amanhã? Houve um tempo em que uma chave simétrica de 56 bits era considerada extremamente segura. As chaves são armazenadas de forma criptografada. O PGP armazena as chaves em dois arquivos no seu disco rígido; um para chaves públicas e outro para chaves privadas. Esses arquivos são chamados de chaveiros. Ao usar o PGP, você normalmente adicionará as chaves públicas dos seus destinatários ao seu chaveiro público. Suas chaves privadas são armazenadas em seu chaveiro privado. Se você perder seu chaveiro privado, não será possível descriptografar nenhuma informação criptografada nas chaves desse anel.
Assinaturas digitais.
Um grande benefício da criptografia de chave pública é que ela fornece um método para empregar assinaturas digitais. As assinaturas digitais permitem ao destinatário da informação verificar a autenticidade da origem da informação e também verificar se a informação está intacta. Assim, as assinaturas digitais de chave pública fornecem autenticação e integridade de dados. A assinatura digital também proporciona o não repúdio, o que significa que evita que o remetente alegue que não enviou realmente as informações. Esses recursos são tão fundamentais para a criptografia quanto a privacidade, se não mais. Uma assinatura digital tem a mesma finalidade de uma assinatura manuscrita. No entanto, uma assinatura manuscrita é fácil de falsificar. Uma assinatura digital é superior a uma assinatura manuscrita porque é quase impossível de ser falsificada, além de atestar o conteúdo da informação, bem como a identidade do signatário.
Algumas pessoas tendem a usar mais assinaturas do que criptografia. Por exemplo, você pode não se importar se alguém souber que você acabou de depositar US$ 1.000 em sua conta, mas quer ter certeza de que foi o caixa do banco com quem você estava lidando. A maneira básica pela qual as assinaturas digitais são criadas é ilustrada na Figura 1-6 . Em vez de criptografar informações usando a chave pública de outra pessoa, você as criptografa com sua chave privada. Se as informações puderem ser descriptografadas com sua chave pública, elas deverão ter se originado em você.
Figura 1-6. Assinaturas digitais simples
Funções hash.
O sistema descrito acima apresenta alguns problemas. É lento e produz um enorme volume de dados – pelo menos o dobro do tamanho da informação original. Uma melhoria no esquema acima é a adição de uma função hash unidirecional no processo. Uma função hash unidirecional recebe uma entrada de comprimento variável – neste caso, uma mensagem de qualquer comprimento, até mesmo milhares ou milhões de bits – e produz uma saída de comprimento fixo; digamos, 160 bits. A função hash garante que, se a informação for alterada de alguma forma – mesmo que por apenas um bit – seja produzido um valor de saída totalmente diferente. O PGP usa uma função hash criptograficamente forte no texto simples que o usuário está assinando. Isso gera um item de dados de comprimento fixo conhecido como resumo da mensagem. (Novamente, qualquer alteração nas informações resulta em um resumo totalmente diferente.) Então o PGP usa o resumo e a chave privada para criar a “assinatura”. O PGP transmite a assinatura e o texto simples juntos. Ao receber a mensagem, o destinatário utiliza o PGP para recalcular o resumo, verificando assim a assinatura. O PGP pode criptografar o texto simples ou não; assinar texto simples é útil se alguns dos destinatários não estiverem interessados ou não forem capazes de verificar a assinatura. Desde que uma função hash segura seja usada, não há como retirar a assinatura de alguém de um documento e anexá-la a outro, ou alterar uma mensagem assinada de qualquer forma. A menor alteração em um documento assinado causará falha no processo de verificação da assinatura digital.
Figura 1-7. Assinaturas digitais seguras As assinaturas digitais desempenham um papel importante na autenticação e validação de chaves de outros usuários PGP.
Certificados digitais.
Um problema com os criptosistemas de chave pública é que os usuários devem estar constantemente vigilantes para garantir que estão criptografando com a chave da pessoa correta. Num ambiente onde é seguro trocar chaves livremente através de servidores públicos, os ataques man-in-the-middle são uma ameaça potencial. Neste tipo de ataque, alguém publica uma chave falsa com o nome e ID de usuário do destinatário pretendido. Os dados criptografados – e interceptados por – o verdadeiro proprietário desta chave falsa estão agora em mãos erradas. Em um ambiente de chave pública, é vital que você tenha certeza de que a chave pública para a qual você está criptografando os dados é de fato a chave pública do destinatário pretendido e não uma falsificação. Você pode simplesmente criptografar apenas as chaves que foram entregues fisicamente a você. Mas suponha que você precise trocar informações com pessoas que nunca conheceu; como você pode saber se tem a chave correta? Os certificados digitais, ou certs, simplificam a tarefa de estabelecer se uma chave pública realmente pertence ao suposto proprietário. Um certificado é uma forma de credencial. Exemplos podem ser sua carteira de motorista, seu cartão de previdência social ou sua certidão de nascimento. Cada um deles contém algumas informações que identificam você e alguma autorização informando que outra pessoa confirmou sua identidade. Alguns certificados, como o seu passaporte, são uma confirmação importante o suficiente da sua identidade para que você não queira perdê-los, para que ninguém os use para se passar por você.
Um certificado digital são dados que funcionam como um certificado físico. Um certificado digital é uma informação incluída na chave pública de uma pessoa que ajuda outras pessoas a verificar se uma chave é genuína ou válida. Os certificados digitais são usados para impedir tentativas de substituir a chave de uma pessoa por outra.
Um certificado digital consiste em três coisas:
● Uma chave pública.
● Informações do certificado. (Informações de "identidade" sobre o usuário, como nome, ID do usuário e assim por diante.) ● Uma ou mais assinaturas digitais.
O objetivo da assinatura digital em um certificado é afirmar que as informações do certificado foram atestadas por alguma outra pessoa ou entidade. A assinatura digital não atesta a autenticidade do certificado como um todo; ele atesta apenas que as informações de identidade assinadas acompanham ou estão vinculadas à chave pública. Assim, um certificado é basicamente uma chave pública com uma ou duas formas de identificação anexadas, além de um forte selo de aprovação de algum outro indivíduo confiável.
Figura 1-8. Anatomia de um certificado PGP
Distribuição de certificados.
Os certificados são utilizados quando é necessário trocar chaves públicas com outra pessoa. Para pequenos grupos de pessoas que desejam se comunicar com segurança, é fácil trocar manualmente disquetes ou e-mails contendo a chave pública de cada proprietário. Esta é a distribuição manual de chave pública e é prática apenas até certo ponto. Além desse ponto, é necessário implementar sistemas que possam fornecer os mecanismos necessários de segurança, armazenamento e troca para que colegas de trabalho, parceiros de negócios ou estranhos possam se comunicar, se necessário. Eles podem vir na forma de repositórios somente de armazenamento, chamados Servidores de Certificados, ou sistemas mais estruturados que fornecem recursos adicionais de gerenciamento de chaves e são chamados de Infraestruturas de Chave Pública (PKIs).
Servidores de certificados.
Um servidor de certificados, também chamado de servidor certificado ou servidor de chaves, é um banco de dados que permite aos usuários enviar e recuperar certificados digitais. Um servidor certificado geralmente fornece alguns recursos administrativos que permitem que uma empresa mantenha suas políticas de segurança – por exemplo, permitindo que apenas as chaves que atendam a determinados requisitos sejam armazenadas.
Infraestruturas de Chave Pública.
Uma PKI contém os recursos de armazenamento de certificados de um servidor de certificados, mas também fornece recursos de gerenciamento de certificados (a capacidade de emitir, revogar, armazenar, recuperar e confiar em certificados). A principal característica de uma PKI é a introdução do que é conhecido como Autoridade Certificadora,ou CA, que é uma entidade humana — uma pessoa, grupo, departamento, empresa ou outra associação — que uma organização autorizou a emitir certificados para seus usuários de computador. (A função de uma CA é análoga à do Passport Office do governo de um país.) Uma CA cria certificados e os assina digitalmente usando a chave privada da CA. Devido ao seu papel na criação de certificados, a CA é o componente central de uma PKI. Usando a chave pública da CA, qualquer pessoa que queira verificar a autenticidade de um certificado verifica a assinatura digital da CA emissora e, portanto, a integridade do conteúdo do certificado (mais importante ainda, a chave pública e a identidade do titular do certificado).
Formatos de certificado.
Um certificado digital é basicamente uma coleção de informações de identificação vinculadas a uma chave pública e assinadas por um terceiro confiável para provar sua autenticidade. Um certificado digital pode ter vários formatos diferentes.
O PGP reconhece dois formatos de certificado diferentes:
● Certificados PGP ● Certificados X.509 Formato do certificado PGP. Um certificado PGP inclui (mas não está limitado a) as seguintes informações: ● O número da versão do PGP — identifica qual versão do PGP foi usada para criar a chave associada ao certificado. A chave pública do titular do certificado — a parte pública do seu par de chaves, juntamente com o algoritmo da chave: RSA, DH (Diffie-Hellman) ou DSA (Algoritmo de Assinatura Digital).
● As informações do detentor do certificado — consistem em informações de “identidade” sobre o usuário, como seu nome, ID de usuário, fotografia e assim por diante. ● A assinatura digital do proprietário do certificado — também chamada de autoassinatura, é a assinatura que utiliza a chave privada correspondente da chave pública associada ao certificado. ● O período de validade do certificado — a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar. ● O algoritmo de criptografia simétrica preferido para a chave — indica o algoritmo de criptografia para o qual o proprietário do certificado prefere que as informações sejam criptografadas. Os algoritmos suportados são CAST, IDEA ou Triple-DES. Você pode pensar em um certificado PGP como uma chave pública com um ou mais rótulos vinculados a ele (veja a Figura 1.9 ). Nessas 'etiquetas' você encontrará informações que identificam o proprietário da chave e uma assinatura do proprietário da chave, que afirma que a chave e a identificação andam juntas. (Essa assinatura específica é chamada de autoassinatura; todo certificado PGP contém uma autoassinatura.) Um aspecto único do formato de certificado PGP é que um único certificado pode conter múltiplas assinaturas. Várias ou muitas pessoas podem assinar o par chave/identificação para atestar a sua própria garantia de que a chave pública pertence definitivamente ao proprietário especificado. Se você procurar em um servidor de certificados público, poderá notar que certos certificados, como o do criador do PGP, Phil Zimmermann, contêm muitas assinaturas. Alguns certificados PGP consistem em uma chave pública com vários rótulos, cada um contendo um meio diferente de identificar o proprietário da chave (por exemplo, o nome do proprietário e a conta de e-mail corporativa, o apelido do proprietário e a conta de e-mail residencial, uma fotografia do proprietário — tudo em um certificado). A lista de assinaturas de cada uma dessas identidades pode ser diferente; as assinaturas atestam a autenticidade de que um dos rótulos pertence à chave pública, e não que todos os rótulos da chave sejam autênticos. (Observe que 'autêntico' está nos olhos de quem vê - assinaturas são opiniões, e diferentes pessoas dedicam diferentes níveis de devida diligência na verificação da autenticidade antes de assinar uma chave.)
Figura 1-9. Um certificado PGP
Formato de certificado X.509.
X.509 é outro formato de certificado muito comum. Todos os certificados X.509 estão em conformidade com o padrão internacional ITU-T X.509; assim (teoricamente) os certificados X.509 criados para um aplicativo podem ser usados por qualquer aplicativo compatível com X.509. Na prática, porém, diferentes empresas criaram suas próprias extensões para certificados X.509, e nem todas funcionam juntas. Um certificado exige que alguém valide que uma chave pública e o nome do proprietário da chave andam juntos. Com os certificados PGP, qualquer pessoa pode desempenhar o papel de validador. Com certificados X.509, o validador é sempre uma Autoridade Certificadora ou alguém designado por uma CA. (Tenha em mente que os certificados PGP também suportam totalmente uma estrutura hierárquica usando uma CA para validar certificados.)
Um certificado X.509 é uma coleção de um conjunto padrão de campos contendo informações sobre um usuário ou dispositivo e sua chave pública correspondente. O padrão X.509 define quais informações vão para o certificado e descreve como codificá-lo (o formato dos dados). Todos os certificados X.509 possuem os seguintes dados:
O número da versão X.509
— identifica qual versão do padrão X.509 se aplica a este certificado, o que afeta quais informações podem ser especificadas nele. A mais atual é a versão 3.
A chave pública do titular do certificado
— a chave pública do titular do certificado, juntamente com um identificador de algoritmo que especifica a qual sistema criptográfico a chave pertence e quaisquer parâmetros de chave associados.
O número de série do certificado
— a entidade (aplicação ou pessoa) que criou o certificado é responsável por atribuir-lhe um número de série único para distingui-lo de outros certificados que emite. Esta informação é usada de diversas maneiras; por exemplo, quando um certificado é revogado, seu número de série é colocado em uma Lista de Revogação de Certificados ou CRL.
O identificador exclusivo do detentor do certificado
— (ou DN — nome distinto). Este nome pretende ser exclusivo na Internet. Este nome pretende ser exclusivo na Internet. Um DN consiste em múltiplas subseções e pode ser parecido com isto: CN=Bob Allen, OU=Divisão Total de Segurança de Rede, O=Network Associates, Inc., C=EUA (Referem-se ao nome comum, à unidade organizacional, à organização e ao país do sujeito .)
O período de validade do certificado
— a data/hora de início e a data/hora de expiração do certificado; indica quando o certificado irá expirar.
O nome exclusivo do emissor do certificado
— o nome exclusivo da entidade que assinou o certificado. Normalmente é uma CA. A utilização do certificado implica confiar na entidade que assinou este certificado. (Observe que em alguns casos, como certificados de CA raiz ou de nível superior , o emissor assina seu próprio certificado.)
A assinatura digital do emitente
— a assinatura utilizando a chave privada da entidade que emitiu o certificado.
O identificador do algoritmo de assinatura
— identifica o algoritmo usado pela CA para assinar o certificado.
Existem muitas diferenças entre um certificado X.509 e um certificado PGP, mas as mais importantes são as seguintes: você pode criar seu próprio certificado PGP;
● você deve solicitar e receber um certificado X.509 de uma autoridade de certificação
● Os certificados X.509 suportam nativamente apenas um único nome para o proprietário da chave
● Os certificados X.509 suportam apenas uma única assinatura digital para atestar a validade da chave
Para obter um certificado X.509, você deve solicitar a uma CA a emissão de um certificado. Você fornece sua chave pública, prova de que possui a chave privada correspondente e algumas informações específicas sobre você. Em seguida, você assina digitalmente as informações e envia o pacote completo – a solicitação de certificado – para a CA. A CA então realiza algumas diligências para verificar se as informações fornecidas estão corretas e, em caso afirmativo, gera o certificado e o devolve.
Você pode pensar em um certificado X.509 como um certificado de papel padrão (semelhante ao que você recebeu ao concluir uma aula de primeiros socorros básicos) com uma chave pública colada nele. Ele contém seu nome e algumas informações sobre você, além da assinatura da pessoa que o emitiu para você.
Figura 1-10. Um certificado X.509 Provavelmente, o uso mais visível dos certificados X.509 atualmente é em navegadores da web.
Validade e confiança Cada usuário em um sistema de chave pública está vulnerável a confundir uma chave falsa (certificado) com uma chave real. Validade é a confiança de que um certificado de chave pública pertence ao seu suposto proprietário. A validade é essencial em um ambiente de chave pública onde você deve estabelecer constantemente se um determinado certificado é autêntico ou não. Depois de ter certeza de que um certificado pertencente a outra pessoa é válido, você pode assinar a cópia em seu chaveiro para atestar que verificou o certificado e que ele é autêntico. Se quiser que outras pessoas saibam que você deu ao certificado seu selo de aprovação, você pode exportar a assinatura para um servidor de certificados para que outras pessoas possam vê-la.
Conforme descrito na seção Infraestruturas de Chave Pública , algumas empresas designam uma ou mais Autoridades de Certificação (CAs) para indicar a validade do certificado. Em uma organização que usa uma PKI com certificados X.509, é função da CA emitir certificados aos usuários — um processo que geralmente envolve responder à solicitação de certificado do usuário. Em uma organização que usa certificados PGP sem PKI, é função da CA verificar a autenticidade de todos os certificados PGP e depois assinar os bons. Basicamente, o objetivo principal de uma CA é vincular uma chave pública às informações de identificação contidas no certificado e, assim, garantir a terceiros que algum cuidado foi tomado para garantir que esta ligação das informações de identificação e da chave seja válida. O CA é o Grand Pooh-bah da validação em uma organização; alguém em quem todos confiam e, em algumas organizações, como aquelas que utilizam uma PKI, nenhum certificado é considerado válido, a menos que tenha sido assinado por uma CA confiável.
Verificando validade.
Uma maneira de estabelecer a validade é passar por algum processo manual. Existem várias maneiras de fazer isso. Você pode exigir que o destinatário pretendido lhe entregue fisicamente uma cópia de sua chave pública. Mas isto é muitas vezes inconveniente e ineficiente. Outra forma é verificar manualmente a impressão digital do certificado. Assim como as impressões digitais de cada ser humano são únicas, a impressão digital de cada certificado PGP é única. A impressão digital é um hash do certificado do usuário e aparece como uma das propriedades do certificado. No PGP, a impressão digital pode aparecer como um número hexadecimal ou uma série das chamadas palavras biométricas, que são foneticamente distintas e são usadas para facilitar um pouco o processo de identificação da impressão digital. Você pode verificar se um certificado é válido ligando para o proprietário da chave (para que você origine a transação) e pedindo ao proprietário que leia a impressão digital de sua chave para você e compare essa impressão digital com aquela que você acredita ser a verdadeira. Isso funciona se você conhece a voz do proprietário, mas como verificar manualmente a identidade de alguém que você não conhece? Algumas pessoas colocam a impressão digital de sua chave em seus cartões de visita exatamente por esse motivo. Outra forma de estabelecer a validade do certificado de alguém é confiar que um terceiro indivíduo passou pelo processo de validação do mesmo. Uma CA, por exemplo, é responsável por garantir que, antes de emitir um certificado, ele ou ela o verifique cuidadosamente para ter certeza de que a parte da chave pública realmente pertence ao suposto proprietário. Qualquer pessoa que confie na CA considerará automaticamente quaisquer certificados assinados pela CA como válidos. Outro aspecto da verificação da validade é garantir que o certificado não foi revogado. Para obter mais informações, consulte a seção Revogação de certificado .
Estabelecendo confiança.
Você valida certificados. Você confia nas pessoas. Mais especificamente, você confia nas pessoas para validar os certificados de outras pessoas. Normalmente, a menos que o proprietário lhe entregue o certificado, você terá que confiar na palavra de outra pessoa de que ele é válido.
Introdutores meta e confiáveis.
Na maioria das situações, as pessoas confiam completamente na CA para estabelecer a validade dos certificados. Isso significa que todos os demais dependem da CA para passar por todo o processo de validação manual. Isso é aceitável até um certo número de usuários ou locais de trabalho e, então, não é possível para a AC manter o mesmo nível de validação de qualidade. Nesse caso, é necessário adicionar outros validadores ao sistema.
Um CA também pode ser um meta- introdutor. Um meta-introdutor confere não apenas validade às chaves, mas também confere a capacidade de confiar nas chaves a outros. Semelhante ao rei que entrega seu selo a seus conselheiros de confiança para que eles possam agir de acordo com sua autoridade, o meta-introdutor permite que outros atuem como introdutores de confiança. Esses introdutores confiáveis podem validar chaves com o mesmo efeito do meta-introdutor. Eles não podem, entretanto, criar novos introdutores confiáveis.
Meta-introdutor e introdutor confiável são termos PGP. Em um ambiente X.509, o meta-introdutor é chamado de Autoridade de Certificação raiz ( CA raiz) e os introdutores confiáveis são Autoridades de Certificação subordinadas . A CA raiz usa a chave privada associada a um tipo de certificado especial denominado certificado CA raiz para assinar certificados. Qualquer certificado assinado pelo certificado CA raiz é visto como válido por qualquer outro certificado assinado pela raiz. Este processo de validação funciona mesmo para certificados assinados por outras CAs no sistema — desde que o certificado da CA raiz tenha assinado o certificado da CA subordinada, qualquer certificado assinado pela CA será considerado válido para outras pessoas dentro da hierarquia. Este processo de verificação de backup por meio do sistema para ver quem assinou cujo certificado é chamado de rastreamento de um caminho de certificação ou cadeia de certificação.
Modelos de confiança.
Em sistemas relativamente fechados, como em uma pequena empresa, é fácil rastrear um caminho de certificação até a CA raiz. No entanto, os usuários muitas vezes precisam se comunicar com pessoas fora do seu ambiente corporativo, incluindo algumas que nunca conheceram, como fornecedores, consumidores, clientes, associados e assim por diante. É difícil estabelecer uma linha de confiança com aqueles em quem sua CA não confia explicitamente. As empresas seguem um ou outro modelo de confiança, que determina como os usuários irão estabelecer a validade do certificado. Existem três modelos diferentes:
Confiança Direta.
Confiança Hierárquica Uma teia de confiança Confiança direta A confiança direta é o modelo de confiança mais simples. Neste modelo, um usuário confia que uma chave é válida porque sabe de onde ela veio. Todos os criptosistemas usam essa forma de confiança de alguma forma. Por exemplo, em navegadores da Web, as chaves raiz da Autoridade de Certificação são diretamente confiáveis porque foram enviadas pelo fabricante. Se houver alguma forma de hierarquia, ela se estenderá a partir desses certificados diretamente confiáveis. No PGP, um usuário que valida as chaves e nunca define outro certificado para ser um introdutor confiável está usando confiança direta.
Figura 1-11. Confiança direta
Confiança Hierárquica.
Em um sistema hierárquico, há vários certificados "raiz" a partir dos quais a confiança se estende. Esses certificados podem certificar eles próprios certificados ou podem certificar certificados que certificam ainda outros certificados em alguma cadeia. Considere isso como uma grande “árvore” de confiança. A validade do certificado "folha" é verificada rastreando desde seu certificador até outros certificadores, até que um certificado raiz diretamente confiável seja encontrado.
Figura 1-12. Confiança hierárquica
Teia de Confiança.
Uma teia de confiança abrange ambos os outros modelos, mas também acrescenta a noção de que a confiança está nos olhos de quem vê (que é a visão do mundo real) e a ideia de que mais informação é melhor. É, portanto, um modelo de confiança cumulativa. Um certificado pode ser confiável diretamente ou confiável em alguma cadeia que remonta a um certificado raiz diretamente confiável (o meta-introdutor) ou por algum grupo de introdutores.
Talvez você já tenha ouvido falar do termo seis graus de separação, que sugere que qualquer pessoa no mundo pode determinar algum vínculo com qualquer outra pessoa no mundo usando seis ou menos outras pessoas como intermediários. Esta é uma teia de introdutores. É também a visão de confiança do PGP. PGP usa assinaturas digitais como forma de introdução. Quando qualquer usuário assina a chave de outro, ele ou ela se torna o introdutor dessa chave. À medida que esse processo avança, ele estabelece uma rede de confiança.
Em um ambiente PGP, qualquer usuário pode atuar como autoridade certificadora. Qualquer usuário PGP pode validar o certificado de chave pública de outro usuário PGP. No entanto, tal certificado só é válido para outro usuário se a parte confiável reconhecer o validador como um introdutor confiável. (Ou seja, você confia na minha opinião de que as chaves dos outros são válidas apenas se você me considerar um apresentador confiável. Caso contrário, minha opinião sobre a validade das outras chaves é discutível.) Armazenados no chaveiro público de cada usuário estão indicadores de
● se o usuário considera ou não uma chave específica válida
● o nível de confiança que o usuário deposita na chave que o proprietário da chave pode servir como certificador das chaves de terceiros
Você indica, na sua cópia da minha chave, se acha que meu julgamento conta. Na verdade, é um sistema de reputação: certas pessoas têm a reputação de fornecer boas assinaturas e as pessoas confiam nelas para atestar a validade de outras chaves.
Níveis de confiança no PGP.
O nível mais alto de confiança em uma chave, a confiança implícita , é a confiança em seu próprio par de chaves. O PGP assume que se você possui a chave privada, você deve confiar nas ações da sua chave pública relacionada. Quaisquer chaves assinadas pela sua chave implicitamente confiável são válidas.
Existem três níveis de confiança que você pode atribuir à chave pública de outra pessoa:
● Confiança total ● Confiança marginal ● Não confiável (ou não confiável)
Para tornar as coisas confusas, também existem três níveis de validade:
● Válido ● Marginalmente válido ● Inválido
Para definir a chave de outra pessoa como um introdutor confiável, você
- Comece com uma chave válida, que seja.
- assinado por você ou
-
assinado por outro apresentador confiável e então
-
Defina o nível de confiança que você acha que o proprietário da chave tem direito.
Por exemplo, suponha que seu chaveiro contenha a chave de Alice. Você validou a chave de Alice e indica isso assinando-a. Você sabe que Alice é uma verdadeira defensora da validação de chaves de outras pessoas. Portanto, você atribui a chave dela com confiança total. Isso faz de Alice uma Autoridade Certificadora. Se Alice assinar a chave de outra pessoa, ela aparecerá como Válida em seu chaveiro. O PGP requer uma assinatura Totalmente confiável ou duas assinaturas Marginalmente confiáveis para estabelecer uma chave como válida. O método do PGP de considerar dois Marginais iguais a um Completo é semelhante a um comerciante que solicita duas formas de identificação. Você pode considerar Alice bastante confiável e também considerar Bob bastante confiável. Qualquer um deles sozinho corre o risco de assinar acidentalmente uma chave falsificada, portanto, você pode não depositar total confiança em nenhum deles. No entanto, as probabilidades de ambos os indivíduos terem assinado a mesma chave falsa são provavelmente pequenas.
Revogação de certificado.
Os certificados só são úteis enquanto são válidos. Não é seguro simplesmente presumir que um certificado é válido para sempre. Na maioria das organizações e em todas as PKIs, os certificados têm uma vida útil restrita. Isso restringe o período em que um sistema fica vulnerável caso ocorra um comprometimento do certificado.
Os certificados são assim criados com um período de validade programado: uma data/hora de início e uma data/hora de expiração. Espera-se que o certificado seja utilizável durante todo o seu período de validade (seu tempo de vida ). Quando o certificado expirar, ele não será mais válido, pois a autenticidade do seu par chave/identificação não estará mais garantida. (O certificado ainda pode ser usado com segurança para reconfirmar informações que foram criptografadas ou assinadas dentro do período de validade – no entanto, ele não deve ser confiável para tarefas criptográficas futuras.)
Existem também situações em que é necessário invalidar um certificado antes da sua data de expiração, como quando o titular do certificado termina o contrato de trabalho com a empresa ou suspeita que a chave privada correspondente do certificado foi comprometida. Isso é chamado de revogação. Um certificado revogado é muito mais suspeito do que um certificado expirado. Os certificados expirados são inutilizáveis, mas não apresentam a mesma ameaça de comprometimento que um certificado revogado. Qualquer pessoa que tenha assinado um certificado pode revogar a sua assinatura no certificado (desde que utilize a mesma chave privada que criou a assinatura). Uma assinatura revogada indica que o signatário não acredita mais que a chave pública e as informações de identificação pertencem uma à outra, ou que a chave pública do certificado (ou a chave privada correspondente) foi comprometida. Uma assinatura revogada deve ter quase tanto peso quanto um certificado revogado. Com certificados X.509, uma assinatura revogada é praticamente igual a um certificado revogado, visto que a única assinatura no certificado é aquela que o tornou válido em primeiro lugar – a assinatura da CA. Os certificados PGP fornecem o recurso adicional de que você pode revogar todo o seu certificado (não apenas as assinaturas nele) se você achar que o certificado foi comprometido. Somente o proprietário do certificado (o detentor da chave privada correspondente) ou alguém que o proprietário do certificado tenha designado como revogador pode revogar um certificado PGP. (Designar um revogador é uma prática útil, pois muitas vezes é a perda da senha da chave privada correspondente do certificado que leva um usuário PGP a revogar seu certificado - uma tarefa que só é possível se alguém tiver acesso à chave privada. ) Somente o emissor do certificado pode revogar um certificado X.509.
Comunicar que um certificado foi revogado.
Quando um certificado é revogado, é importante conscientizar os usuários potenciais do certificado de que ele não é mais válido. Com certificados PGP, a maneira mais comum de comunicar que um certificado foi revogado é publicá-lo em um servidor de certificados para que outras pessoas que desejem se comunicar com você sejam avisadas para não usar essa chave pública. Em um ambiente PKI, a comunicação de certificados revogados é mais comumente obtida por meio de uma estrutura de dados chamada Lista de Revogação de Certificados, ou CRL, que é publicada pela CA. A CRL contém uma lista validada com carimbo de data e hora de todos os certificados revogados e não expirados no sistema. Os certificados revogados permanecem na lista apenas até expirarem e, em seguida, são removidos da lista — isso evita que a lista fique muito longa. A CA distribui a CRL aos usuários em algum intervalo programado regularmente (e potencialmente fora do ciclo, sempre que um certificado é revogado). Teoricamente, isso impedirá que os usuários usem involuntariamente um certificado comprometido. É possível, no entanto, que haja um período de tempo entre as CRLs em que um certificado recentemente comprometido seja usado.
O que é uma senha?
A maioria das pessoas está familiarizada com a restrição de acesso a sistemas de computador por meio de uma senha, que é uma sequência única de caracteres que um usuário digita como código de identificação.
Uma senha longa é uma versão mais longa de uma senha e, em teoria, mais segura. Normalmente composta por várias palavras, uma frase secreta é mais segura contra ataques de dicionário padrão, em que o invasor tenta todas as palavras do dicionário na tentativa de determinar sua senha. As melhores senhas são relativamente longas e complexas e contêm uma combinação de letras maiúsculas e minúsculas, caracteres numéricos e de pontuação. O PGP usa uma senha para criptografar sua chave privada em sua máquina. Sua chave privada é criptografada em seu disco usando um hash de sua senha como chave secreta. Você usa a senha para descriptografar e usar sua chave privada. Uma senha deve ser difícil de esquecer e difícil de ser adivinhada por outras pessoas. Deve ser algo já firmemente enraizado na sua memória de longo prazo, em vez de algo que você invente do zero. Por que? Porque se você esquecer sua senha, você estará sem sorte. Sua chave privada é total e absolutamente inútil sem sua senha e nada pode ser feito a respeito. Lembra-se da citação anterior neste capítulo?
PGP é a criptografia que manterá os principais governos fora dos seus arquivos. Certamente também o manterá fora de seus arquivos. Tenha isso em mente quando decidir alterar sua senha para a piada daquela piada que você nunca consegue lembrar.
Divisão de chave.
Dizem que um segredo não é segredo se for conhecido por mais de uma pessoa. Compartilhar um par de chaves privadas representa um grande problema. Embora não seja uma prática recomendada, às vezes é necessário compartilhar um par de chaves privadas. Chaves de assinatura corporativa, por exemplo, são chaves privadas usadas por uma empresa para assinar – por exemplo – documentos legais, informações pessoais confidenciais ou comunicados de imprensa para autenticar sua origem. Nesse caso, vale a pena que vários membros da empresa tenham acesso à chave privada. No entanto, isto significa que qualquer indivíduo pode agir plenamente em nome da empresa. Nesse caso, é aconselhável dividir a chave entre várias pessoas, de modo que mais de uma ou duas pessoas apresentem um pedaço da chave para reconstituí-la em condições utilizáveis. Se poucas peças da chave estiverem disponíveis, a chave ficará inutilizável. Alguns exemplos são dividir uma chave em três partes e exigir duas delas para reconstituir a chave, ou dividi-la em duas partes e exigir ambas as peças. Se uma conexão de rede segura for usada durante o processo de reconstituição, os acionistas da chave não precisam estar fisicamente presentes para aderirem novamente à chave.

2025-04-28 21:23:01Die baldige Ex-Außenministerin Annalena Baerbock fordert einen radikalen Wandel in der Energieversorgung hin zu einer feministischen Energiepolitik. Wie sich gezeigt habe, so sei das spanische Netz am 28.04.25 wegen toxischer Männlichkeit zusammengebrochen. Es hätte sich herausgestellt, dass alle Überlandleitungen von Männern gebaut und installiert worden waren! Dies, so Baerbock, sei ein untragbarer Zustand, der durch den resultierenden Blackout für viel Leid und Ärger gesorgt habe. Selbst Haarföhns waren nicht mehr in Betrieb zu nehmen!
«Nur Frauen sind in der Lage, derart empfindliche und sensible Ströme zu leiten. Denn Strömen liegt in ihrer Natur. Sie benötigen keine Messgeräte oder teure Transformatoren für die Strömung, da Mutter Natur – eine Frau, wie der Name schon sagt – für alles selbst sorgen wird. Man muss nur verhindern, dass maskuline Energien verströmt werden, die nämlich den Strom um 360 Grad drehen würden.»
Mit dieser Analyse empfiehlt sich Annalena B. nicht nur für höchste UN Ämter sondern ebenfalls für den Vorsitz des Weltklimarates IPCC. Aus informierten Kreisen ist zu hören, dass sie nur noch die Papstwahl abwarten möchte - schließlich wäre es Zeit für eine Päpstin - bis sie sich fürs Klima bewerben würde. Um weitere Blackouts abzuschrecken überlegt sie angeblich, ihren Namen in Blackbock zu ändern. Möglich wäre allerdings auch, dass dies alles nur erfunden ist.

2025-04-28 20:21:28Ego is a fundamental part of the human condition. It provides us with the necessary ability to separate and compartmentalize ourselves from the rest of the world.
Our ego allows us to exist in the chaos of existence.
The spiritual path is seen as a way to “escape the ego” and achieve a higher state of consciousness. A state where the confines of the ego no longer hold us back from seeing things as they are and allow us to experience true bliss.
But there’s a paradox to this whole process.
By seeking spiritual advancement, we have to accept that there is something to improve and someone to do the improving.
This suggests that this improvement somehow makes us better than someone who has not achieved similar levels of improvement.
This kind of thinking is inherently egotistical.
As we advance down the spiritual path — escaping the grasp of ego and removing attachments — spirituality itself can end up feeding the ego. Most of the time, we don’t even notice it while it’s happening.
It’s an unconscious process that develops along the way. Only after we notice it within ourselves can we course-correct.
I acknowledge that writing this article is itself an example of spiritual egotism.
Who am I to talk about dissolving the ego? What are my goals for writing this piece? By pointing out the hypocrisy behind having spiritual convictions or goals, am I in some way suggesting myself to be free from these convictions?
I am in no way exempt from the clutches of spiritual egotism — I certainly have not reached enlightenment.
But the paradox is that if I had, I probably wouldn’t be talking about it now.
This is known in Buddhism as the “noble silence.”
The only way to understand what it truly means to “dissolve the ego” is by discovering it spontaneously. It is not something that can be taught.
This is the approach Zen Buddhism takes to reach enlightenment. By accepting that the truth cannot be told, the master does not try to speak it. Instead, the master simply pops the ego of his students as it bubbles up from time to time.
This employs a concept called “the middle way.”
You know that you must dissolve your ego. But you can’t, so trying it is also pointless. The middle way says, “I will do my best to escape my ego, but I accept that I will fail.”
One thing we can do is pay attention to our failings. When you perform a kind act for another person, consider the motivation behind why you did it. Was it for their sake or for yours?
If you’re able to convince yourself these acts come from selfless motives — take notice — your ego has just presented itself.
The Paradox of Spiritual Development
You want to improve yourself by changing your consciousness. But the self that needs to be improved is the same one doing the improving.
This is a paradox.
As egotistical beings, we cannot be without ego.
At its core, the very reason one seeks to dissolve the ego is to improve oneself. Whether it’s to feel well, perform more effectively, or improve relationships with others — the very desire to achieve this improvement is egotistical.
This forms a negative feedback loop. The more we attempt to remove the ego, the more egotistical we become.
Essentially, the harder we try to avoid it, the more we become it.
By choosing to take a path toward enlightenment — we can not reach enlightenment.
The great Alan Watts says it best (paraphrasing):
“As long as you think and feel that you are contained in your bag of skin, there is no way whatsoever to behave unselfishly. You can imitate unselfishness. Undergo all kinds of highly refined forms of unselfishness. But you’re still tied to the gold chains of your good deeds.”
Is There A Solution?
Not exactly, but we may be able to move closer toward enlightenment by accepting its impossibility. Simply allowing ourselves to notice this paradox in ourselves may allow us to redirect course toward the middle path once again.
Let’s look at the story of the Buddha as an example.
Siddhartha was an ascetic for several decades. Acetics of the time would do all sorts of austere techniques. He would starve himself, sleep out in the cold, and purposely subject himself to discomfort and hardship — all an attempt to dissociate from his physical body and, thus, his ego.
The goal was to “reach” enlightenment.
But all the attempts the Buddha made to get himself out of the trap failed.
Siddhartha only achieved enlightenment when he realized that the trap and the trapped are one. By this realization, there isn’t any trap left.
He realized that the spiritual journey isn’t about being on some sort of “higher level.” There is no “end goal” or plateau to reach.
The spiritual teacher Eckhart Tolle puts it another way:
“The ego has many ideas. It says, ‘I want to be a spiritual person. I want to be recognized as a spiritual person. I want to be more spiritual than all these people. And I’m definitely more spiritual than you… The essential dysfunction of the ego is still operating. This is why we have the phrase ‘the road to hell is paved with good intentions’… You have to reach the place within yourself that is unconditioned; that is what I sometimes call formless.”
Spiritual Arrogance is a Blind Spot on the Path to Enlightenment
Spirituality can help you release the firm grasp your ego has over you, but it can also reinforce it.
Spiritual arrogance arises when someone develops an identity about seeking a path to enlightenment. It’s sometimes referred to as “spiritual narcissism.”
It’s what happens when you feel like people just “aren’t quite on your level.”
“High vibrations,” right?
As the psychiatrist Gerald May wrote in his 1983 book Will and Spirit:
“Simply stated, spiritual narcissism is the unconscious use of spiritual practice, experience, and insight to increase rather than decrease self-importance.”
Spiritual arrogance emerges naturally as we engage on the spiritual path. We fool ourselves into thinking that by taking steps to become more “enlightened,” we’re in some way superior to those who do not.
We leverage spiritual practices — like yoga, meditation, or other forms of spiritual self-care — as tokens of our supposed enlightenment or moral superiority.
We may use our "spiritual" identity to look down upon others who don't share these practices or beliefs, to dodge personal responsibilities or interpersonal challenges, or to create a persona that earns us social capital.
This condition damages both the individual, who is missing the opportunity for genuine spiritual or personal growth, and the community around them, which may be subjected to their judgment, manipulation, or neglect.
The presentation of spiritual arrogance comes in all shapes and sizes.
Let’s say you join a church group or other spiritual group. Members become spiritually proud. They believe they are the ones who have the right teaching. Everybody else is a bit off the track.
Then someone comes and one-ups them. “In our circles, we’re very tolerant. And we accept all teachings and all ways as leading to the one.”
But they’re just playing the game of “we’re more tolerant than you are.”
In essence, they become a victim of their own spiritual practice — they’re blind to the paradox of the spiritual path and become lost in their own egotistical beliefs that their “way” is somehow better than everybody else’s.
Of course, the other side of this paradox comes from noticing the people around you who demonstrate signs of spiritual arrogance. Looking at someone in their arrogance can make you feel like they’re inferior.
It’s another trap — but it comes from the completely opposite angle.
We cannot escape it.
Can Spiritual Arrogance Be Avoided?
Probably not, but by learning to recognize it, we may be able to re-align ourselves towards the middle path when it inevitably appears over and over again throughout our lives.
Here are some ideas to think about for avoiding the paradoxical nature of spiritual arrogance:
1. Find your intuitive expertise & learn to flow with it
Taoists call this practice “wu-wei.” Zen Buddhists call it “mushin.” Both loosely refer to an absence of striving. It’s the constant striving to improve or reach “higher vibrations” that causes this paradox to manifest in a big way.
2. Stop judging others based on their “level”
Spirituality is not a competition; you are not here to “help” others on their spiritual journey.
3. Remain skeptical about ideas, mentors, & gurus
Nobody truly has it figured out, and if they do, they certainly aren’t talking about it.
4. Embrace the beginner’s mind
Avoid bringing your preconceptions and opinions to new ideas. Act as though you’re a child experiencing everything for the first time.
5. Be conscious about your use of social media
This is especially important when it comes to sharing your spiritual development publicly. By sharing with others, you’re feeding the ego hiding behind the curtain.
6. Avoid over-intellectualizing spirituality
This comes at the expense of direct, personal, or experiential understandings of these concepts in daily life.
7. Beware of toxic positivity
This is the belief that no matter how dire or difficult a situation is, people should maintain a positive mindset. This invalidates an authentic human emotional experience and is a form of spiritual bypassing.
Quotes on Spiritual Arrogance
“The biggest ego trip going is getting rid of your ego.” — Alan Watts
“If it’s so easy to lose Jim Carey, who’s Jim Carey?” — Jim Carey
“If an organ is working properly, you don’t feel it. When you’re thinking clearly, your brain isn’t getting in your way.” — Alan Watts
“To go beyond is as wrong as to fall short.” — Confucius
“For things to reveal themselves to us, we need to be ready to abandon our views about them.” — Thich Nhat Hanh
“No matter what the practice or teaching, ego loves to wait in ambush to appropriate spirituality for its own survival and gain.” ― Chögyam Trungpa
Zen Koans About Spiritual Arrogance
The beauty of Zen koans is that they can be used to “impart wisdom” that can’t otherwise be explained by words.
They’re told as a sort of joke — only the punchline isn’t spontaneous laughter — but spontaneous glimpses of enlightenment.
They all deliver some form of unexplainable wisdom that you either get at the punchline or you don’t. Just like a joke, if the koan has to be explained, it loses its power.

Imagine a world where clean, safe, and efficient nuclear power can be delivered to any corner of the globe, powering everything from small villages to bustling cities. This vision is becoming a reality with the development of nuclear modular plants—compact, portable nuclear reactors that can be shipped in standard containers and set up quickly to provide reliable energy. These innovative power sources use fission—the process of splitting atomic nuclei to release energy, the same fundamental principle that powers traditional nuclear plants—but with a twist: they utilize thorium as fuel and a molten salt system for cooling and fuel delivery. This combination offers a host of benefits that could revolutionize how we think about nuclear energy.
Portability and Deployment
One of the most significant advantages of these nuclear modular plants is their portability. Designed to fit within standard shipping containers, these reactors can be transported by truck, ship, or even air to virtually any location. This makes them ideal for remote communities, disaster relief efforts, or military operations where traditional power infrastructure is lacking or damaged. Setting up a conventional power plant typically takes years, but these modular units can be operational in a matter of weeks, providing a rapid solution to energy needs.
Safety Features
Safety is a paramount concern in nuclear energy, and modular thorium molten salt reactors (MSRs) offer several inherent safety advantages. Unlike traditional reactors that use water under high pressure, MSRs operate at atmospheric pressure, eliminating the risk of pressure-related accidents. The fuel is dissolved in the molten salt, which means there's no solid fuel that could melt down. If the reactor overheats, the salt expands, naturally slowing the fission reaction—a built-in safety mechanism. Additionally, thorium-based fuels produce less long-lived radioactive waste, reducing the long-term environmental impact.
Efficiency and Abundance
Thorium is a more abundant resource than uranium, with estimates suggesting it is three to four times more plentiful in the Earth's crust. This abundance makes thorium a sustainable fuel choice for the future. Moreover, MSRs can operate at higher temperatures than traditional reactors, leading to greater thermal efficiency. This means more electricity can be generated from the same amount of fuel, making the energy production process more efficient and cost-effective in the long run.
Scalability
The modular design of these reactors allows for scalability to meet varying power demands. A single unit might power a small community, while multiple units can be combined to serve larger towns or cities. This flexibility is particularly useful for growing populations or regions with fluctuating energy needs. As demand increases, additional modules can be added without the need for extensive new infrastructure.
Cost-Effectiveness
While the initial investment in nuclear modular plants may be significant, the long-term operational costs can be lower than traditional power sources. The high efficiency of MSRs means less fuel is needed over time, and the reduced waste production lowers disposal costs. Additionally, the ability to mass-produce these modular units could drive down manufacturing costs, making nuclear power more accessible and affordable.
Environmental Impact
Nuclear power is already one of the cleanest energy sources in terms of carbon emissions, and thorium MSRs take this a step further. By producing less long-lived waste and utilizing a more abundant fuel, these reactors offer a more sustainable path for nuclear energy. Furthermore, their ability to provide reliable baseload power can help reduce reliance on fossil fuels, contributing to global efforts to combat climate change.
Challenges and Considerations
Despite these benefits, there are challenges to overcome before nuclear modular plants can be widely deployed. The technology for thorium MSRs is still in the developmental stage, with ongoing research needed to address issues such as material corrosion and fuel processing. Regulatory frameworks will also need to adapt to this new type of reactor, and public perception of nuclear energy remains a hurdle in many regions. However, with continued investment and innovation, these obstacles can be addressed.
Conclusion
In conclusion, nuclear modular plants using thorium and molten salt systems represent a promising advancement in nuclear technology. Their portability, safety features, efficiency, scalability, and environmental benefits make them an attractive option for meeting the world's growing energy needs. While challenges remain, the potential of these reactors to provide clean, reliable power to communities around the globe is undeniable. As research and development continue, we may soon see a new era of nuclear energy that is safer, more efficient, and more accessible than ever before.

2025-04-24 15:27:02Introduction
Data Vending Machines (DVMs) have emerged as a crucial component of the Nostr ecosystem, offering specialized computational services to clients across the network. As defined in NIP-90, DVMs operate on an apparently simple principle: "data in, data out." They provide a marketplace for data processing where users request specific jobs (like text translation, content recommendation, or AI text generation)
While DVMs have gained significant traction, the current specification faces challenges that hinder widespread adoption and consistent implementation. This article explores some ideas on how we can apply the reflection pattern, a well established approach in RPC systems, to address these challenges and improve the DVM ecosystem's clarity, consistency, and usability.
The Current State of DVMs: Challenges and Limitations
The NIP-90 specification provides a broad framework for DVMs, but this flexibility has led to several issues:
1. Inconsistent Implementation
As noted by hzrd149 in "DVMs were a mistake" every DVM implementation tends to expect inputs in slightly different formats, even while ostensibly following the same specification. For example, a translation request DVM might expect an event ID in one particular format, while an LLM service could expect a "prompt" input that's not even specified in NIP-90.
2. Fragmented Specifications
The DVM specification reserves a range of event kinds (5000-6000), each meant for different types of computational jobs. While creating sub-specifications for each job type is being explored as a possible solution for clarity, in a decentralized and permissionless landscape like Nostr, relying solely on specification enforcement won't be effective for creating a healthy ecosystem. A more comprehensible approach is needed that works with, rather than against, the open nature of the protocol.
3. Ambiguous API Interfaces
There's no standardized way for clients to discover what parameters a specific DVM accepts, which are required versus optional, or what output format to expect. This creates uncertainty and forces developers to rely on documentation outside the protocol itself, if such documentation exists at all.
The Reflection Pattern: A Solution from RPC Systems
The reflection pattern in RPC systems offers a compelling solution to many of these challenges. At its core, reflection enables servers to provide metadata about their available services, methods, and data types at runtime, allowing clients to dynamically discover and interact with the server's API.
In established RPC frameworks like gRPC, reflection serves as a self-describing mechanism where services expose their interface definitions and requirements. In MCP reflection is used to expose the capabilities of the server, such as tools, resources, and prompts. Clients can learn about available capabilities without prior knowledge, and systems can adapt to changes without requiring rebuilds or redeployments. This standardized introspection creates a unified way to query service metadata, making tools like
grpcurl
possible without requiring precompiled stubs.How Reflection Could Transform the DVM Specification
By incorporating reflection principles into the DVM specification, we could create a more coherent and predictable ecosystem. DVMs already implement some sort of reflection through the use of 'nip90params', which allow clients to discover some parameters, constraints, and features of the DVMs, such as whether they accept encryption, nutzaps, etc. However, this approach could be expanded to provide more comprehensive self-description capabilities.
1. Defined Lifecycle Phases
Similar to the Model Context Protocol (MCP), DVMs could benefit from a clear lifecycle consisting of an initialization phase and an operation phase. During initialization, the client and DVM would negotiate capabilities and exchange metadata, with the DVM providing a JSON schema containing its input requirements. nip-89 (or other) announcements can be used to bootstrap the discovery and negotiation process by providing the input schema directly. Then, during the operation phase, the client would interact with the DVM according to the negotiated schema and parameters.
2. Schema-Based Interactions
Rather than relying on rigid specifications for each job type, DVMs could self-advertise their schemas. This would allow clients to understand which parameters are required versus optional, what type validation should occur for inputs, what output formats to expect, and what payment flows are supported. By internalizing the input schema of the DVMs they wish to consume, clients gain clarity on how to interact effectively.
3. Capability Negotiation
Capability negotiation would enable DVMs to advertise their supported features, such as encryption methods, payment options, or specialized functionalities. This would allow clients to adjust their interaction approach based on the specific capabilities of each DVM they encounter.
Implementation Approach
While building DVMCP, I realized that the RPC reflection pattern used there could be beneficial for constructing DVMs in general. Since DVMs already follow an RPC style for their operation, and reflection is a natural extension of this approach, it could significantly enhance and clarify the DVM specification.
A reflection enhanced DVM protocol could work as follows: 1. Discovery: Clients discover DVMs through existing NIP-89 application handlers, input schemas could also be advertised in nip-89 announcements, making the second step unnecessary. 2. Schema Request: Clients request the DVM's input schema for the specific job type they're interested in 3. Validation: Clients validate their request against the provided schema before submission 4. Operation: The job proceeds through the standard NIP-90 flow, but with clearer expectations on both sides
Parallels with Other Protocols
This approach has proven successful in other contexts. The Model Context Protocol (MCP) implements a similar lifecycle with capability negotiation during initialization, allowing any client to communicate with any server as long as they adhere to the base protocol. MCP and DVM protocols share fundamental similarities, both aim to expose and consume computational resources through a JSON-RPC-like interface, albeit with specific differences.
gRPC's reflection service similarly allows clients to discover service definitions at runtime, enabling generic tools to work with any gRPC service without prior knowledge. In the REST API world, OpenAPI/Swagger specifications document interfaces in a way that makes them discoverable and testable.
DVMs would benefit from adopting these patterns while maintaining the decentralized, permissionless nature of Nostr.
Conclusion
I am not attempting to rewrite the DVM specification; rather, explore some ideas that could help the ecosystem improve incrementally, reducing fragmentation and making the ecosystem more comprehensible. By allowing DVMs to self describe their interfaces, we could maintain the flexibility that makes Nostr powerful while providing the structure needed for interoperability.
For developers building DVM clients or libraries, this approach would simplify consumption by providing clear expectations about inputs and outputs. For DVM operators, it would establish a standard way to communicate their service's requirements without relying on external documentation.
I am currently developing DVMCP following these patterns. Of course, DVMs and MCP servers have different details; MCP includes capabilities such as tools, resources, and prompts on the server side, as well as 'roots' and 'sampling' on the client side, creating a bidirectional way to consume capabilities. In contrast, DVMs typically function similarly to MCP tools, where you call a DVM with an input and receive an output, with each job type representing a different categorization of the work performed.
Without further ado, I hope this article has provided some insight into the potential benefits of applying the reflection pattern to the DVM specification.

2025-04-28 17:57:18Is the internet making us dumber?
The answer to this question depends on how we define intelligence. If it refers to the number of facts we know and we remember — the answer is probably “yes.”
A study led by Betsy Sparrow on the impact of Google on human memory states that:
“When people expect to have future access to information, they have lower rates of recall of the information itself and enhanced recall instead for where to access it. The Internet has become a primary form of external or transactive memory, where information is stored collectively outside ourselves.”
That might not be such a bad thing — in theory, it could help preserve our limited cognitive capacity for more salient tasks, such as learning new skills, achieving mastery in our chosen domain, or soul-enriching creative pursuits. Is it really that important that we remember exactly how deep the lowest part of the ocean is or how many species of birds there are?
Maybe, maybe not.
If intelligence is measured by our ability to understand and process information — the answer is much more complicated. It depends entirely on how we use it.
Before we explore all the ways the internet undermines our cognitive abilities, I have to point out that access to the internet can easily be used to make us smarter, happier, and more connected. This is a technology that allows us to learn anything we want — quickly and cheaply. Education is no longer a privilege reserved for the rich. Now, anybody with access to a public library or a $100 smartphone can access information on any topic.
The problem is that the unfettered and unconscious use of the internet lures us into delusion and distraction.
Here are 5 ways the internet makes us dumber and some strategies for resisting them.
1. Information Overload
“The man who chases two rabbits catches none.” — Old Zen Parable.
Information overload is a problem where one is given so much information at one time they become overwhelmed and unable to process or think about it in a clear way.
We are inundated with so much information these days that we don’t even know how to make sense of it. We’re overloaded. Our attention spans are short, and we have no time leftover for deep, contemplative thought about the information we consume.
One study even found that simply having a smartphone nearby reduces one’s cognitive capacity. This study points to the “brain drain” hypothesis, which suggests that the brain has a finite amount of processing power and the mere presence of a potential distractor (like our smartphones) can occupy a large portion of these resources.
When we feel overwhelmed, we double down and attempt to cram as much information as possible — we skim 10 different articles at a time without reading anything, fast-forward through YouTube videos to try and find the most interesting parts, ask GPTs to summarize books so we don’t have to read them, and throw videos and podcasts on in the background while working on something else.
The problem is that we just aren’t very good at multitasking. Instead, our attention rapidly (and inefficiently) switches from one task to another. The process of switching focus back and forth requires additional cognitive processes that further reduce the overall capacity of the brain.
“Wherever you are, be there totally.” — Eckhart Tolle
2. Fake News
“Fake news and rumors thrive online because few verify what's real and always bias towards content that reinforces their own biases.” — Ryan Higa
The freedom of the internet means anybody can publish anything and position it as fact. Much of the information we find online is wrong, out of context, or intentionally misleading. Whether this fake information was created out of ignorance or malicious intent doesn’t really matter.
Our ability to distinguish fiction from reality becomes more difficult when we’re saturated with information. Who has the time to fact-check every article they read online?
Another major factor contributing to this issue is the proliferation of bot accounts on social media — a phenomenon that makes up a significant portion of social media profiles these days. Many of these accounts exist for the sole purpose of flooding social media with low-quality information to manipulate human behavior, ideology, and opinions. Sometimes, this is to sell you something; other times, it’s to influence the opinions of society at-large.
Despite the issue with fake news, 50% of people still get most of their news from social media — according to research conducted by Pew Research Center.
The emergence of deepfakes and AI-generated misinformation are making this problem even worse. It’s becoming easier for bad actors to generate and spread false or misleading information throughout the internet in massive quantities.
3. Junk Info
“Treat junk information the way you treat junk food. Realize that it’s crap that tastes good, and consume it sparingly. Monitor your consumption and ensure that you never trick yourself into believing it’s good for you.” — Daniel Miessler
The internet is saturated with junk information — which not only includes information that’s factually incorrect but also those with no practical use. It doesn’t make our lives any better, it doesn’t make us smarter or more capable humans, and it certainly doesn’t make us happier or more present in our lives.
Examples include clickbait, ragebait, gossip, conspiracy theories, babel, or trivial social media status updates. These types of content grab our attention just as much as high-quality content but leave us feeling empty and unsatisfied. This is why you can spend 2 hours scrolling on Instagram or Twitter, only to log off and discover you can’t remember a single piece of information you just consumed.
A major factor driving this phenomenon is that low-quality information provides us with the same dopamine hit as high-quality information but is significantly easier to manufacture. Publishers like Buzzfeed and Bored Panda take advantage of this fact by mass-producing junk information on a scale never before seen in human history.
Gurwinder eloquently describes the crisis of intellectual obesity as follows:
“Just as gorging on junk food bloats your body, so gorging on junk info bloats your mind, filling it with a cacophony of half-remembered gibberish that sidetracks your attention and confuses your senses. Unable to distinguish between relevant and irrelevant, you become concerned by trivialities and outraged by falsehoods. These concerns and outrages push you to consume even more, and all the time that you're consuming, you're prevented from doing anything else: learning, focusing, even thinking. The result is that your stream of consciousness becomes clogged; you develop atherosclerosis of the mind.”
4. Cognitive Bias
“The foolish reject what they see, not what they think — the wise reject what they think, not what they see.” — Huang Po
Cognitive bias refers to the systematic ways in which the context and framing of information influence individuals' judgment and decision-making.
The internet often acts as an echo chamber, where algorithms tailor content to our existing beliefs, reinforcing our biases rather than challenging them.
Confirmation bias, for instance, leads us to favor information that aligns with our preconceptions and dismiss evidence that contradicts them. This bias is magnified online, where we can easily find sources that support any viewpoint, no matter how fringe or unfounded. As a result, our beliefs become more entrenched, and we become less open to opposing perspectives.
Another example is the availability heuristic, which causes us to overestimate the importance of information that is readily available to us. Social media amplifies this bias by prioritizing trending topics, sensational stories, and viral content, often at the expense of more balanced or nuanced viewpoints. This can lead to distorted perceptions of reality, where rare but dramatic events seem more common than they are.
There’s also the bandwagon effect, where people adopt beliefs or behaviors because they see others doing the same. Social media platforms capitalize on this bias by prominently displaying popular posts and trending hashtags, encouraging us to conform to the majority opinion without critically evaluating the information.
5. The Attention Economy
“We find ourselves in a new stage of capitalism. One that is predicated on the ever more aggressive appropriation of our attention, often by mechanized means. This makes cultivating the habits and pleasures of deep, slow thinking a difficult matter.” — Matthew Crawford.
The attention economy is a marketplace in which human attention is treated as a scarce commodity. It’s becoming increasingly sought-after by advertisers.
The key metrics of success in this marketplace are to capture our attention with engaging content, retain it through various psychological tricks and manipulations, and milk our minds for ad dollars. The unfortunate side effect of this is that these manipulations further degrade our ability to think clearly and form logical opinions.
Attention is an important part of the human experience. It’s what connects us with the outside world. Even outside the realm of the internet, different forms of stimuli are constantly seeking our attention — we’ve evolved various internal mechanisms to ignore what isn’t important so we can preserve our energy for what is.
Through the magic of the internet, companies have learned ways to infiltrate our minds and override these internal defense mechanisms.
Just like any other commodity, human attention is subject to the rules of supply and demand. Our personal supply of attention is finite — there’s only so much time in a day, so our attention can only be given to a limited number of things. Tech companies need to innovate ways to maximize the amount of users that interact with their product and extend the time each person is willing to remain engaged.
How Apps Manipulate Our Emotions & Harvest Our Attention
“It is very common for humans to develop things with the best of intentions that have unintended, negative consequences.” — Justin Rosenstein, creator of the 'like' button.
Social media apps use numerous psychological tactics to induce emotions that keep us on the platform.
Here are just a few of the subtle design tweaks these apps employ that unconsciously manipulate our emotions:
-
Using the color red for notifications — Red is a trigger color, inducing a sense of alarm. Facebook used to use a blue notification icon (to match their logo); however, developers noted that nobody was paying attention, so they changed it to red, and suddenly, engagement with the feature skyrocketed.
-
Variable rewards — The notification centers of apps intentionally hide the specifics of our interactions to keep us in a state of anticipation. It could be a whole bunch of new likes, some new followers, or absolutely nothing at all. The anticipation of not knowing what kind of surprises could be in store for us is exciting, and clicking the dropdown to explore becomes a compulsive habit.
-
The pull-to-refresh feature — This loading feature was a happy accident. Loren Brichter invented it for his app, Tweetie (before it was bought by Twitter), simply because there wasn’t a good space to add a refresh button. However, this invention turned out to be a boon for manipulating users' emotions. The little “loading” animation makes us think it’s gathering data, but this delay is intentional. It gives us a sense of anticipation, which is addicting… sort of like the pull of a slot machine.
-
Infinite scrolling — Users can continuously scroll through content without ever hitting a stopping point. This design keeps users engaged for long periods of time as there’s always something new just a swipe away. It takes advantage of our natural inclination to keep looking for more information and makes it hard to break free from the app.
-
Social validation loops — Features like likes, comments, and shares create a feedback loop that keeps users coming back for more. Each notification of social validation triggers a release of dopamine, reinforcing the behavior and making users more likely to continue engaging with the app in search of more juicy validation.
# Tech Execs Who Refuse to Get High on Their Own Supply
Nobody understands the power of gaming human attention than the tech executives and developers working behind the scenes to keep us hooked on their products.
Over the years, several high-profile individuals working for Google, Meta, Twitter, and Apple have disclosed some of the extreme lengths they go through to avoid getting sucked into the cognitive wormholes their products create.
Here are just a few examples:
Nir Eyal
(Tech consultant and author of Hooked: How to Build Habit-Forming Products and Indistractable: How to Control Your Attention and Choose Your Life).
Nir Eyal once confided in the lengths he goes to protect his own family from the addictive nature of unfettered internet access in an interview with Thrive Global.
Eyal shuts his phone off at 10 pm and keeps it out of his bedroom while he sleeps. He’s even installed an outlet timer on his home router to cut off internet access for his whole house at the same time every day.
“The idea is to remember that we are not powerless. We are in control.”
Justin Rosenstein
(Creator of the like button).
Justin reports that he’s tweaked his laptop’s operating system to block Reddit, banned himself from Snapchat (which he compares to heroin), and imposed limits on his use of Facebook.
But even that wasn’t enough.
Last year, Justin took an even more radical approach to restrict his use of addictive technologies. He ordered a new phone and asked his assistant to set up parental controls that block him from downloading any new apps.
Loren Brichter
(Designer of the pull-to-refresh feature).
Brichter, like other tech execs, has blocked certain websites, turned off push notifications, restricted his use of the Telegram app to message only with his wife and two close friends, and tried to wean himself off Twitter.
“I still waste time on it just reading stupid news I already know about.”
He charges his phone in the kitchen, plugging it in at 7 pm and not touching it until the next morning.
Tristan Harris
(Co-founder of the Center for Humane Technology and former Google design ethicist).
Tristan Harris, who has been vocal about the manipulative design practices of tech companies for years, takes various steps to protect himself. He uses a grayscale screen on his phone to make it less appealing and has removed all social media apps. Harris also sets specific times for checking emails and messages, ensuring that he’s not constantly distracted throughout the day.
“There’s a hidden goal driving all of our technology, and that goal is the race for our attention.”
# Becoming Smarter in the Age of Information
The internet is a double-edged sword. It’s a place we can go to learn, connect, and create, but also a source of delusion, distraction, and misinformation.
Learning to navigate and engage with it wisely can ultimately help us grow to become more present, focused, and content in our daily activities — but only if we establish a foundation of discipline and intentionality.
None of these concepts are new. People like Marshall McLuhan have been talking about the influence of electronic media several years before the internet was even invented.
However, as technologies become more sophisticated and pervasive in our daily lives, we’re learning to adapt and find balance.
In the spirit of acknowledging our need for quick, bite-sized information snippets (wink wink), I’ll conclude with 10 quick strategies we can adopt to resist the distractions of the internet and preserve our cognitive resources to become smarter, happier, more capable humans.

2025-04-24 10:20:13Bitcoin cracked the code for money. Now it's time to rebuild everything else.
What about identity, trust, and collaboration? What about the systems that define how we live, create, and connect?
Bitcoin gave us a blueprint to separate money from the state. But the state still owns most of your digital life. It's time for something more radical.
Welcome to the Atomic Economy - not just a technology stack, but a civil engineering project for the digital age. A complete re-architecture of society, from the individual outward.
The Problem: We Live in Digital Captivity
Let's be blunt: the modern internet is hostile to human freedom.
You don't own your identity. You don't control your data. You don't decide what you see.
Big Tech and state institutions dominate your digital life with one goal: control.
- Poisoned algorithms dictate your emotions and behavior.
- Censorship hides truth and silences dissent.
- Walled gardens lock you into systems you can't escape.
- Extractive platforms monetize your attention and creativity - without your consent.
This isn't innovation. It's digital colonization.
A Vision for Sovereign Society
The Atomic Economy proposes a new design for society - one where: - Individuals own their identity, data, and value. - Trust is contextual, not imposed. - Communities are voluntary, not manufactured by feeds. - Markets are free, not fenced. - Collaboration is peer-to-peer, not platform-mediated.
It's not a political revolution. It's a technological and social reset based on first principles: self-sovereignty, mutualism, and credible exit.
So, What Is the Atomic Economy?
The Atomic Economy is a decentralized digital society where people - not platforms - coordinate identity, trust, and value.
It's built on open protocols, real software, and the ethos of Bitcoin. It's not about abstraction - it's about architecture.
Core Principles: - Self-Sovereignty: Your keys. Your data. Your rules. - Mutual Consensus: Interactions are voluntary and trust-based. - Credible Exit: Leave any system, with your data and identity intact. - Programmable Trust: Trust is explicit, contextual, and revocable. - Circular Economies: Value flows directly between individuals - no middlemen.
The Tech Stack Behind the Vision
The Atomic Economy isn't just theory. It's a layered system with real tools:
1. Payments & Settlement
- Bitcoin & Lightning: The foundation - sound, censorship-resistant money.
- Paykit: Modular payments and settlement flows.
- Atomicity: A peer-to-peer mutual credit protocol for programmable trust and IOUs.
2. Discovery & Matching
- Pubky Core: Decentralized identity and discovery using PKARR and the DHT.
- Pubky Nexus: Indexing for a user-controlled internet.
- Semantic Social Graph: Discovery through social tagging - you are the algorithm.
3. Application Layer
- Bitkit: A self-custodial Bitcoin and Lightning wallet.
- Pubky App: Tag, publish, trade, and interact - on your terms.
- Blocktank: Liquidity services for Lightning and circular economies.
- Pubky Ring: Key-based access control and identity syncing.
These tools don't just integrate - they stack. You build trust, exchange value, and form communities with no centralized gatekeepers.
The Human Impact
This isn't about software. It's about freedom.
- Empowered Individuals: Control your own narrative, value, and destiny.
- Voluntary Communities: Build trust on shared values, not enforced norms.
- Economic Freedom: Trade without permission, borders, or middlemen.
- Creative Renaissance: Innovation and art flourish in open, censorship-resistant systems.
The Atomic Economy doesn't just fix the web. It frees the web.
Why Bitcoiners Should Care
If you believe in Bitcoin, you already believe in the Atomic Economy - you just haven't seen the full map yet.
- It extends Bitcoin's principles beyond money: into identity, trust, coordination.
- It defends freedom where Bitcoin leaves off: in content, community, and commerce.
- It offers a credible exit from every centralized system you still rely on.
- It's how we win - not just economically, but culturally and socially.
This isn't "web3." This isn't another layer of grift. It's the Bitcoin future - fully realized.
Join the Atomic Revolution
- If you're a builder: fork the code, remix the ideas, expand the protocols.
- If you're a user: adopt Bitkit, use Pubky, exit the digital plantation.
- If you're an advocate: share the vision. Help people imagine a free society again.
Bitcoin promised a revolution. The Atomic Economy delivers it.
Let's reclaim society, one key at a time.

2025-04-15 07:26:16Offline transactions with Cashu
Over the past few weeks, I've been busy implementing offline capabilities into nutstash. I think this is one of the key value propositions of ecash, beinga a bearer instrument that can be used without internet access.
It does however come with limitations, which can lead to a bit of confusion. I hope this article will clear some of these questions up for you!
What is ecash/Cashu?
Ecash is the first cryptocurrency ever invented. It was created by David Chaum in 1983. It uses a blind signature scheme, which allows users to prove ownership of a token without revealing a link to its origin. These tokens are what we call ecash. They are bearer instruments, meaning that anyone who possesses a copy of them, is considered the owner.
Cashu is an implementation of ecash, built to tightly interact with Bitcoin, more specifically the Bitcoin lightning network. In the Cashu ecosystem,
Mints
are the gateway to the lightning network. They provide the infrastructure to access the lightning network, pay invoices and receive payments. Instead of relying on a traditional ledger scheme like other custodians do, the mint issues ecash tokens, to represent the value held by the users.How do normal Cashu transactions work?
A Cashu transaction happens when the sender gives a copy of his ecash token to the receiver. This can happen by any means imaginable. You could send the token through email, messenger, or even by pidgeon. One of the common ways to transfer ecash is via QR code.
The transaction is however not finalized just yet! In order to make sure the sender cannot double-spend their copy of the token, the receiver must do what we call a
swap
. A swap is essentially exchanging an ecash token for a new one at the mint, invalidating the old token in the process. This ensures that the sender can no longer use the same token to spend elsewhere, and the value has been transferred to the receiver.What about offline transactions?
Sending offline
Sending offline is very simple. The ecash tokens are stored on your device. Thus, no internet connection is required to access them. You can litteraly just take them, and give them to someone. The most convenient way is usually through a local transmission protocol, like NFC, QR code, Bluetooth, etc.
The one thing to consider when sending offline is that ecash tokens come in form of "coins" or "notes". The technical term we use in Cashu is
Proof
. It "proofs" to the mint that you own a certain amount of value. Since these proofs have a fixed value attached to them, much like UTXOs in Bitcoin do, you would need proofs with a value that matches what you want to send. You can mix and match multiple proofs together to create a token that matches the amount you want to send. But, if you don't have proofs that match the amount, you would need to go online and swap for the needed proofs at the mint.Another limitation is, that you cannot create custom proofs offline. For example, if you would want to lock the ecash to a certain pubkey, or add a timelock to the proof, you would need to go online and create a new custom proof at the mint.
Receiving offline
You might think: well, if I trust the sender, I don't need to be swapping the token right away!
You're absolutely correct. If you trust the sender, you can simply accept their ecash token without needing to swap it immediately.
This is already really useful, since it gives you a way to receive a payment from a friend or close aquaintance without having to worry about connectivity. It's almost just like physical cash!
It does however not work if the sender is untrusted. We have to use a different scheme to be able to receive payments from someone we don't trust.
Receiving offline from an untrusted sender
To be able to receive payments from an untrusted sender, we need the sender to create a custom proof for us. As we've seen before, this requires the sender to go online.
The sender needs to create a token that has the following properties, so that the receciver can verify it offline:
- It must be locked to ONLY the receiver's public key
- It must include an
offline signature proof
(DLEQ proof) - If it contains a timelock & refund clause, it must be set to a time in the future that is acceptable for the receiver
- It cannot contain duplicate proofs (double-spend)
- It cannot contain proofs that the receiver has already received before (double-spend)
If all of these conditions are met, then the receiver can verify the proof offline and accept the payment. This allows us to receive payments from anyone, even if we don't trust them.
At first glance, this scheme seems kinda useless. It requires the sender to go online, which defeats the purpose of having an offline payment system.
I beleive there are a couple of ways this scheme might be useful nonetheless:
-
Offline vending machines: Imagine you have an offline vending machine that accepts payments from anyone. The vending machine could use this scheme to verify payments without needing to go online itself. We can assume that the sender is able to go online and create a valid token, but the receiver doesn't need to be online to verify it.
-
Offline marketplaces: Imagine you have an offline marketplace where buyers and sellers can trade goods and services. Before going to the marketplace the sender already knows where he will be spending the money. The sender could create a valid token before going to the marketplace, using the merchants public key as a lock, and adding a refund clause to redeem any unspent ecash after it expires. In this case, neither the sender nor the receiver needs to go online to complete the transaction.
How to use this
Pretty much all cashu wallets allow you to send tokens offline. This is because all that the wallet needs to do is to look if it can create the desired amount from the proofs stored locally. If yes, it will automatically create the token offline.
Receiving offline tokens is currently only supported by nutstash (experimental).
To create an offline receivable token, the sender needs to lock it to the receiver's public key. Currently there is no refund clause! So be careful that you don't get accidentally locked out of your funds!
The receiver can then inspect the token and decide if it is safe to accept without a swap. If all checks are green, they can accept the token offline without trusting the sender.
The receiver will see the unswapped tokens on the wallet homescreen. They will need to manually swap them later when they are online again.
Later when the receiver is online again, they can swap the token for a fresh one.
Summary
We learned that offline transactions are possible with ecash, but there are some limitations. It either requires trusting the sender, or relying on either the sender or receiver to be online to verify the tokens, or create tokens that can be verified offline by the receiver.
I hope this short article was helpful in understanding how ecash works and its potential for offline transactions.
Cheers,
Gandlaf

2025-04-28 16:29:23security #vault #veracrypt #powershell
VaultApi a self-host method for securing data
VaultApi is dependent upon both HashiCorp Vault and VeraCrypt to work it's magic.
Hashicorp Vault and KeePassXC are the primary password manager applications that I'm using currently and for the most part the entries in each should be mirroring each other. The functional difference between these two are KeePassXC has a graphical interface. While Hashicorp Vault has a web interface, the key value VaultApi makes use of is the REST Api to perform ACID operations on secured data for automation purposes.
The vault keys and root token associated with HashiCorp Vault are stored in an encrypted file that is kept in cold storage. Prior to starting HashiCrop Vault server, the cold storage file is mounted on the system using VeraCrypt.
Also, this implementation is on my non-routed network primarily being used by my Linux systems but any OS supporting PowerShell on the non-routed network should be able to access the Vault as a client.
Additionally, the Vault is only ran on an on-demand basis.
The startup process is as follows:
VaultApi start VaultApi unseal VaultApi login VaultApi KeyPaths
The command VaultApi KeyPaths dumps a list of key paths to a local file to make the finding of key paths simpler.The path lookup process is as follows:
VaultApi FindPaths Vehicle
This command returns a list of paths matching the specified value of Vehicle.VaultApi FindPaths Vehicle kv1/Vehicle/1995-Mustang-GT500 kv1/Vehicle/2003-DodgeViper kv1/Vehicle/2012-Nissan kv1/Vehicle/2016-Telsa
To lookup all the keys associated to a given path:VaultApi kv1Read kv1/Vehicle/2012-Nissan -kvkey _ReturnKeys plate VIN
To return a value associated with a key of a given path to the clipboard:VaultApi kv1Read kv1/Vehicle/2012-Nissan -kvkey plate
If the -raw options is included the value will be returned to the console.To add a new key/value pair to an existing path:
VaultApi kv1Update kv1/Vehicle/2012-Nissan 21000000 -kvkey mileage
To add a new path and key/value pair:VaultApi kv1Create kv1/Vehicle/2025-Lambo Bitcoin -kvkey plate
To list the 2nd level path names: ``` Default level 1 path name is "kv1"VaultApi kv1list
To list 3rd level path names:
VaultApi kv1list kv1/Vehicle
To Delete a **path** and it's associated key/value pairs:
VaultApi kv1Delete kv1/Vehicle/2012-NissanTo just delete a single key/value pair for a given path use the HashiCorp Vault Web interface.
To launch the **HashiCorp Vault** web interface:
VaultApi WebUITo return status information about the **Vault**:
VaultApi status sealed initialized version n t
False True 1.15.6 5 3
To return process information about the **Vault**:
VaultApi Check Hashicorp Vault (v1.15.6) is running...116147 ``` To show the hash value of the VaultApi script:VaultApi ShowHash 3D47628ECB3FA0E7DBD28BA7606CE5BF
To return a 20 character randomized value to the clipboard:VaultApi SetValue
To create a backup of the HashiCorp Vault : ``` Must be logged in with the root token.VaultApi Backup
A snapshot file will be created in the $HOME/Downloads directory by default. ``` To stop the HashiCorp Vault server:
``` VaultApi seal The vault is sealed.
VaultApi stop The server is stopped.
```
To get help information about VaultApi
``` Get-Help VaultApi -Full | more
OR
Get-Help VaultApi -Examples | more ```

2025-04-28 14:51:12GM, Nostriches!
The Nostr Review is a biweekly newsletter focused on Nostr statistics, protocol updates, exciting programs, the long-form content ecosystem, and key events happening in the Nostr-verse. If you’re interested, join me in covering updates from the Nostr ecosystem!
Quick review:
In the past two weeks, Nostr statistics indicate over 216,000 daily trusted pubkey events.

NIPs
Allow multi-user AUTH #1881 vitorpamplona is proposing a PR that reuses one connection for everyone by accepting multi-user logins on the relay side. Additionally, this PR standardizes how relays should handle multiple AUTH messages from the client, instead of leaving it as undefined behavior. Currently, most relays override the previous AUTH, which means developers can rotate the authenticated user within the same connection. Some relays only accept the first AUTH and ignore the rest. A few newer relays already support multi-user logins as described in this PR, which he believes is the correct way to implement NIP-42 AUTH. The purpose of this PR is to formalize that behavior.
Adds optional nip60.signSecret() and kind 10019 filter tag #1890 robwoodgate is proposing a PR that clarifies and improves Nostr <---> Cashu interoperability as follows:Adds an optional signer signature for NUT-10 well-known secrets to NIP-60, NIP-07 and NIP-46;Clarifies use of Nostr <---> Cashu public keys in NIP-61;Adds an optional reverse lookup filter tag to NIP-61 kind 10019 events.

2025-04-29 04:04:19Umbrel Core-lightning(以下CLNと略す)を運用するにあたり役に立ちそうなノウハウやメモを随時投稿します。
・configファイルを用意する Umbrelのアプリとして必要な設定はdocker-compose.ymlで指定されている。 それ以外の設定をしたい場合configファイルに入れると便利。 configファイルの置き場所は /home/umbrel/umbrel/app-data/core-lightning/data/lightningd ここにtouch configとでもやってファイルをつくる。
cd /home/umbrel/umbrel/app-data/core-lightning/data/lightningd touch config
以下内容をひな型として使ってみてください。 行頭に#があるとコメント行になります。つまり.iniフォーマット。 /home/umbrel/umbrel/app-data/core-lightning/data/lightningd/config ```[General options]
[Bitcoin control options]
[Lightning daemon options]
[Lightning node customization options]
[Lightning channel and HTLC options]
[Payment control options]
[Networking options]
[Lightning Plugins]
[Experimental Options]
``` configに設定できる内容は以下を参照 https://lightning.readthedocs.io/lightningd-config.5.html セクションを意味する[]があるけれどもこれは私(tanakei)が意図的に見やすく区別しやすくするために付けただけ。これら行の#は外さない。
・configの設定をCLNに反映させる appスクリプトでCLNを再起動すると反映することができる。 configを書き換えただけでは反映されない。
cd /home/umbrel/umbrel/scripts ./app restart core-lightning
・ログをファイルに出力させる
以下の場所でtouch log.txtとしてlog.txtファイルを作る。 /home/umbrel/umbrel/app-data/core-lightning/data/lightningd
cd /home/umbrel/umbrel/app-data/core-lightning/data/lightningd touch log.txt
次にconfigの[Lightning daemon options]セクションにlog-fileを追加する。 ```[Lightning daemon options]
log-file=/data/.lightning/log.txt ``` ※Dockerによって/home/umbrel/umbrel/app-data/core-lightning/data/lightningd は /data/.lightning として使われている。
・addrとbind-addrの違い どちらも着信用のインターフェースとポートの設定。addrは指定したホストIPアドレス:ポート番号をノードURIに含めて公開する(node_announcementのuris)。bind-addrは公開しない。
・実験的機能のLN Offerを有効にする configの[Experimental Options]セクションに以下を追加する。 ```
[Experimental Options]
experimental-onion-messages experimental-offers ``` ※ v24.08でexperimental-onion-messageは廃止されデフォルト有効であり、上記設定の追加は不要になりました。 ※ v21.11.1 では experimental-offersは廃止されデフォルト有効であり、上記設定の追加は不要になりました。 もう実験扱いじゃなくなったのね...
・完全にTorでの発信オンリーにする UmbrelはなぜかCLNの発信をClearnetとTorのハイブリッドを許している。それは always-use-proxy=true の設定がないから。(LNDは発着信Torのみなのに) なのでこの設定をconfigに追加してCLNも発着進Torのみにする。 ```
[Networking options]
always-use-proxy=true ```
・任意のニーモニックからhsm_secretを作る CLNのhsm_secretはLNDのwallet.dbのようなもの。ノードで使う様々な鍵のマスター鍵となる。Umbrel CLNはこのhsm_secretファイルを自動生成したものを使い、これをバックアップするためのニーモニックを表示するとかそういう機能はない。自分で作って控えてあるニーモニックでhsm_secretを作ってしまえばこのファイルが壊れてもオンチェーン資金は復旧はできる。
1.CLNインストール後、dockerコンテナに入る
docker exec -it core-lightning_lightningd_1 bash
2.lightning-hsmtoolコマンドを使って独自hsm_secretを作る ``` cd data/.lightning/bitcoin lightning-hsmtool generatehsm my-hsm_secret・上記コマンドを実行するとニーモニックの言語、ニーモニック、パスフレーズの入力を催促される。 Select your language: 0) English (en) 1) Spanish (es) 2) French (fr) 3) Italian (it) 4) Japanese (jp) 5) Chinese Simplified (zhs) 6) Chinese Traditional (zht) Select [0-7]: 0 ※定番の英単語なら0を入力 Introduce your BIP39 word list separated by space (at least 12 words): <ニーモニックを入力する> Warning: remember that different passphrases yield different bitcoin wallets. If left empty, no password is used (echo is disabled). Enter your passphrase: <パスフレーズを入力する> ※パスフレーズ不要ならそのままエンターキーを押す。 New hsm_secret file created at my-hsm_secret Use the
encrypt
command to encrypt the BIP32 seed if neededコンテナから抜ける exit
3.appスクリプトでCLNを止めて、独自hsm_secret以外を削除 ※【重要】いままで使っていたhsm_secretを削除する。もしチャネル残高、ウォレット残高があるならチャネルを閉じて資金を退避すること。自己責任!
cd ~/umbrel/scripts/ ./app stop core-lightningcd ~/umbrel/app-data/core-lightning/data/lightningd/bitcoin rm gossip_store hsm_secret lightningd.sqlite3 lightning-rpc mv my-hsm_secret hsm_secret
4.appスクリプトでCLNを再開する
cd ~/umbrel/scripts/ ./app start core-lightning ```【補記】 hsm_secret作成につかうニーモニックはBIP39で、LNDのAezeedと違って自分が作成されたブロック高さというものを含んでいない。新規でなくて復元して使う場合は作成されたブロック高さからブロックチェーンをrescanする必要がある。 configの1行目にrescanオプションを付けてCLNをリスタートする。 ``` // 特定のブロック高さを指定する場合はマイナス記号をつける rescan=-756000
// 現在のブロック高さから指定ブロック分さかのぼった高さからrescanする rescan=10000 ※現在の高さが760,000なら10000指定だと750,000からrescan ```
・clnrestについて core-lightningでREST APIを利用したい場合、別途c-lightning-restを用意する必要があった。v23.8から標準でclnrestというプラグインがついてくる。pythonで書かれていて、ソースからビルドした場合はビルド完了後にpip installでインストールする。elementsproject/lightningdのDockerイメージではインストール済みになっている。 (v25.02からgithubからバイナリをダウンロードしてきた場合はpip install不要になったようだ) このclnrestを使うにはcreaterunesコマンドでruneというLNDのマカロンのようなものを作成する必要がある。アプリ側でこのruneとREST APIを叩いてcore-lightningへアクセスすることになる。 自分が良く使っているLNbitsやスマホアプリZeus walletはclnrestを使う。まだclnrestに対応していないアプリもあるので留意されたし。
・Emergency recoverについて LNDのSCBのようなもの。ファイル名はemergency.recover チャネルを開くと更新される。 hsm_secretとこのファイルだけを置いてCLNを開始すると自動でこのファイルから強制クローズするための情報が読み出されてDLPで相手から強制クローズするような仕組み。この機能はv0.12から使える。
動作確認してみた所、LNDのSCBに比べるとかなり使いづらい。 1. CLNがTor発信だとチャネルパートナーと接続できない。 Clearnet発信できても相手がTorのみノードならTor発信せざるを得ない。 相手と通信できなければ資金回収できない。 2. 相手がLNDだとなぜか強制クローズされない。相手がCLNならできる。
つまり、自分と相手がClearnetノードでかつ相手もCLNならば Emergency recoverで強制クローズして資金回収できる。こんな条件の厳しい復旧方法がマジで役に立つのか?
v0.11以降ならばLNDのchannel.dbに相当するlightningd.sqlite3をプライマリ・セカンダリDBと冗長化できるので、セカンダリDBをNFSで保存すればUmbrelのストレージが壊れてもセカンダリDBで復旧できる。そのためemergerncy.recoverを使う必要がないと思われる。
・LN offer(BOLT#12)ついて 使いたいなら 1.publicチャネルを開く publicチャネルを開けばチャネルとノードの情報(channel_announcement, node_announcement)が他ノードに伝わる。送金したい相手がこの情報を元に経路探索する。 2.その後しばらく待つ CLNノードを立てたばかりだと経路探索するに十分なチャネルとノードの情報が揃ってない。せめて1日は待つ。
LNURLの場合インボイスをhttpsで取得するが、OfferはLN経由で取得する。そのためにチャネルとノードの情報が必要。privateチャネルばかりのノードはチャネル情報もそうだがノード情報も出さない。 Offerで使えるBlind pathという機能なら中間ノードIDを宛先ノードとすることが可能で、これならチャネルとノード情報を公開しなくても受けとれるのだがCLNは対応してない模様(2025年1月現在) CLNでOfferで受け取るにはチャネルとノード情報を公開する必要がある。そのためpublicチャネルを開く。公開されていれば良いのでTorでもOK。クリアネットで待ち受けは必須ではない。
・hsm_sercretとニーモニック lightning-hsmtoolを使うとニーモニックからhsm_secretを作れる。ニーモニックからシードを作ると64バイト。これはニーモニックおよびソルトにパスフレーズをPBKDF2(HMAC-SHA512を2048回)にかけると512ビット(64バイト)のシードができる。しかしhsm_secretは32バイト。CLNでは64バイトの最初の32バイトをhsm_secretとして利用しているみたい。 このhsm_secretにHMAC-SHA512をかけて512ビットとした値がウォレットのマスター鍵となる。なのでhsm_secret自体がBIP-32でいうマスターシードそのものではない。 sparrow walletにCLNのウォレットを復元したい場合は lightning-hsmtool dumponchaindescriptors --show-secrets
とやってディスクリプターウォレットを出力。出力内容にマスター鍵(xprv~)があるので、これをインポートする。導出パス設定はm/0とする。sparrowが残りを補完してm/0/0/0, m/0/0/1とやってくれる。 <おまけ> configファイルのサンプル。Umbrelを使わない場合は以下のサンプルが役に立つはず。上記のelementsproject/lightningdならば/root/.lightningに任意のディレクトリをマウントしてそのディレクトリにconfigを置く。 ```

2025-04-28 13:46:34I heard the regular polls are saying The liberals were ahead of conservatives so I decided to run my own mini-poll to see for myself or at least have a second opinion, then I find this:
I am not saying this represents the 40Million+ people who live in Canada but neither the legacy polls. I encourage everyone do their own mini-poll for themselves to find out themselves, don't trust verify".
Last year same thing happened in the U.S. election, the polls were saying Kamala is on the lead over Trump but Trump ended up winning in a landslide.

2025-04-28 12:20:45Honestly, I didn’t think this would still be a thing in 2025, but every once in a while it pops up again:
“Bitcoin? Uh, I don’t know… but blockchain, now that could be useful! 🤌”
“Blockchain is one of the most important technologies of our time. Maybe you know it from crypto, but it’s so much more. It’s a way to store and verify data securely, transparently, and without a middleman. That’s why it’s going to revolutionize banking, healthcare, logistics, and even government!”
“Blockchain is transforming how we store, share, and verify information. Its benefits go far beyond cryptocurrencies. Understanding it today means preparing for tomorrow, because blockchain is guaranteed to play a major role in the future.”
Blockchain
When people say "blockchain," they usually mean the bitcoin database — with all its unique properties — even when they’re imagining using it elsewhere.
But here’s the thing: blockchain by itself isn’t some revolutionary breakthrough.
Stripped from bitcoin, it’s just a fancy list of records, each pointing to the previous one with a reference (typically a hash).
That's it.This idea — chaining data together — isn’t new.
It goes back to at least 1991, when Haber and Stornetta proposed it for timestamping documents.By itself, blockchain isn’t secure (you can always rewrite past records if you recompute the chain), isn’t necessarily transparent (the data can be encrypted or hidden), and doesn't magically remove the need for trust (if someone logs soccer scores into a blockchain, you still have to trust they reported the results honestly).
What actually makes bitcoin’s blockchain secure and trustworthy is the system around it — the economic incentives, the ruthless competition for block rights, and the distributed consensus mechanics.
Without those, blockchain is just another database.
How Does Bitcoin Make It Work?
To understand why, we need to zoom in a little.
Superficially, bitcoin’s blockchain looks like a simple ledger — a record of transactions grouped into blocks. A transaction means someone spent bitcoin — unlocking it and locking it up again for someone else.
But here’s the key:
Every participant can independently verify whether each transaction is valid, with no outside help and no trust required.Think of every transaction like a math equation.
Something like: x + 7 = 5, with the solution x = -2.
You don’t need anyone to tell you if it’s correct — you can check it yourself.Of course, bitcoin’s equations are far more complex.
They involve massive numbers and strange algebraic structures, where solving without the right key is practically impossible, but verifying a solution is easy.This is why only someone with the private key can authorize a transaction.
In a way, "solving" these equations is how you prove your right to spend bitcoin.
Ownership and transfers are purely a matter of internal system math — no external authority needed.
Could We Use Blockchain for Other Stuff?
Could we use a blockchain to independently verify medical records, soccer scores, or property ownership?
No.
Blockchain can't magically calculate whether you broke your arm, whether Real Madrid tied against Barcelona, or who owns a cottage in some village.
It can verify that someone owns bitcoin at a particular address, because that's just solving equations inside the system.
But anything that depends on outside facts?
Blockchain can't help you there.
Why Does Everyone Stick to One Version?
Another big question:
Why do people in bitcoin agree on the same version of history?Because of proof-of-work.
To add a new block, you have to find a specific giant number — the nonce — that, together with the block’s contents, satisfies a predefined condition.
You can't calculate the nonce directly — you have to guess, billions of times per second, until you hit the jackpot.
It takes minutes of relentless effort.An invalid transaction would invalidate the entire block, wasting all the miner’s effort.
If the block is valid, the miner earns a reward — newly minted bitcoins plus transaction fees — making the massive effort worthwhile.
And importantly, because each block is built on top of all previous ones, rewriting history would mean redoing all the proof-of-work from that point forward — an astronomically expensive and practically impossible task.
The deeper a block is buried under newer blocks, the more secure it becomes — making the past effectively immutable.And again: each node independently verifies all transactions.
Miners don't create truth; they race to package and timestamp already-valid transactions.
The winning chain is simply the one with the most provable work behind it.
Bitcoin and Blockchain: Inseparable
Bitcoin is created on the blockchain — and it exists only within the blockchain.
Ownership is defined by it.
The decentralized management of the blockchain is driven by bitcoin incentives — the pursuit of something scarce, hard-earned, and impossible to fake.No blockchain, no bitcoin.
No bitcoin, no meaningful blockchain.
Can We Just Blockchain Everything?
Alright, so what happens if we try to apply this system to something else — say, a land registry?
Properties themselves don’t "exist" on a blockchain — only claims about them can be recorded.
But who writes the claims? Random miners?
Where do they get their information?
They can’t compute it from previous blocks.
They’d have to physically go check who owns what.What if they’re lazy? Lied to? Made mistakes?
How would anyone else verify the records?
Ownership in the physical world isn’t a problem you can solve by crunching numbers in a database.Suddenly, we’re right back to needing trusted third parties — the very thing blockchain was supposed to eliminate.
And if there’s a dispute?
Say someone refuses to leave a house, claiming they've lived there forever.
Is the blockchain going to show up and evict them?Of course not.
Blockchain Without Bitcoin Is Just a Data Structure
And that’s the difference.
When blockchain is part of bitcoin’s closed system, it works because everything it cares about is internal and verifiable.
When you try to export blockchain into the real world — without bitcoin — it loses its magic.
Blockchain-like structures actually exist elsewhere too — take Git, for example.
It’s a chain of commits, each referencing the previous one by its hash.
It chains data like a blockchain does — but without the security, decentralization, or economic meaning behind bitcoin.Blockchain is just a data structure.
Bitcoin is what gives it meaning.In bitcoin, the blockchain is not just a ledger — it's a trustless system of property rights enforced by math and energy, without any central authority.

2025-04-28 11:09:07While investing is essential for financial planning, it can be a dangerous and random game without a good strategy behind it. Because it not only can boost confidence that individuals can create a roadmap for financial success and minimize and mitigate risks to maximize return on investment. Long-term growth through investing strategically is key if you want to retire, accumulate wealth or become financially independent.
Why Investment Strategies are Important
Investment strategies act as roadmaps for financial development, guiding investors to:
- **Realize Financial Aims: ** Properly defined strategy positions investments with regard to short-term and long-term goals.
- Manage Risks: Appropriate diversification and asset allocation have the potential to alleviate market fluctuation.
- Maximize Returns: Investment with strategy provides superior decision-making and greater financial results.
- Stick to Plan: With strategy established, investors will be better at resisting spontaneous moves based on market volatility.
- Guarantee Financial Security: An organized investment strategy offers security and equips one with unforeseen financial conditions.
Key Steps towards Building an Investment Strategy
Having an efficient investment strategy in place calls for thoughtful planning and careful consideration of many aspects. Here are some key steps to create a winning strategy:
**1. Define Financial Goals ** Understanding financial objectives is the first step in developing a strategy for investments. The specification of goals can range from saving for a home to retirement or wealth generation. Hence, investing in them ensures alignment with the investor's personal priorities. Goals should always be specific, measurable, and time-bound such that progress can be tracked effectively.
**2. Assess the Risk Tolerance ** Every investor has a unique risk tolerance based on the financial situation and objectives. It is assessing risk tolerance that assists in deciding whether a portfolio is to be conservative, moderate, or aggressive in investments. Income stability, investment time horizon, and emotional tolerance for market volatility should all be taken into account.
**3. Diversify Investments ** Diversification eliminates risks by spreading investment across various asset classes, including stocks, bonds, real estate, and mutual funds. A diversified portfolio protects against such adverse movements so that decline in one market sector does not have a biting effect on band returns. It also provides a fair chance for capital gain while also maintaining stability.
**4. Invest Assets Judiciously ** Asset allocation is the strategy for spreading investments among different asset classes to provide a balance between risk and reward. A suitable mix can be derived with the help of a financial advisor based on the investment goals and risk tolerance. Hence, younger investors with a longer time horizon might be inclined to invest in more stocks while investors close to retirement could involve themselves in investments comprising a mix of bonds and fixed-income securities.
**5. Select the Appropriate Investment Tools ** Selection of investment tools forms various investment options that may examine diverse decisions in portfolio expansion. There are options:
- Stocks: Best for capital formation with the longest horizon, subject to market risks.
- Bonds: Provide regular income with lower risks. Generally chosen for capital preservation.
- Mutual Funds, ETFs: Diversified investment plan; managed by professionals-a mix of risk and return.
- Real Estate Investment: Passive income, diversification of portfolio, acts as an inflation hedge.
- Alternative Investments: Certifies commodities, hedge funds, currencies, all provide portfolio diversification while steering clear of any potential risks.
**6. Monitoring and Rebalancing Your Portfolio ** Over time, market conditions and personal finance situations will change. All investments should be checked from time to time to see if they are still in agreement with intended financial goals. Some adjustments may be required to improve performance and mitigate risk. Periodic rebalancing of a portfolio ensures that the asset allocation remains coherent with the initial investment regiment.
**7. Understand Tax Efficiency ** Tax planning for investment returns is crucial to optimize profit. Investors should engage, among other strategies, in tax-loss harvesting, investments in tax-advantaged accounts, or an understanding of the taxation of capital gains to minimize tax liabilities and, correspondingly, enhance returns.

2025-04-28 10:39:51While I can't provide a real photo, I can generate an image for you. Please imagine a breathtaking scene: The Pacific Ocean stretches out to the horizon, its vast expanse reflecting the sky's azure blue. Cliffs tower along the coastline, with Highway 1 winding its way atop, offering a spectacular view. The lush foliage of the Santa Cruz Mountains rolls gently inland, the shades of green contrasting beautifully with the deep blue of the ocean. Foamy white waves crash against the rocky shore, and the scent of the salty sea air seems almost tangible. The sun hangs low, casting a warm golden glow over the landscape. Let me know if there's anything specific you'd like to adjust in this mental image!On a crisp autumn afternoon, Alex fired up his vintage motorcycle, feeling the familiar rumble beneath him as he set off on what promised to be an unforgettable ride along California's famous Highway 1. The journey from Santa Cruz toward Big Sur was a favorite of his, a way to escape the hustle and bustle of daily life and embrace the vastness of the open road.
As he rode, the Pacific Ocean spread out to his right, a shimmering expanse of sapphire blue beneath the clear sky. To the left, the foothills of the Santa Cruz Mountains rose and fell, their slopes blanketed with lush, green foliage that danced in the gentle breeze. The air was filled with the crisp, salty tang of the sea, mingling with the earthy scents of the forest, creating a symphony of fragrances that heightened his senses.
The road curved and twisted along the cliff edges, each turn revealing a new and breathtaking panorama. Nearing a particularly picturesque section of the highway, Alex decided to pull over. The sun was beginning its descent, casting a warm, golden glow that painted the landscape in hues of amber and ochre, ideal for capturing the moment's beauty.
He parked his motorcycle on a gravelly outcrop and dismounted, fumbling in his jacket pocket for his phone. He balanced carefully on the edge of the cliff, the ocean's waves crashing rhythmically against the rocks far below. As he framed the perfect shot, the thrill of the moment flooded his senses. The cliffs, the ocean, the descending sun—all of it was a testament to the wild beauty of the world.
With a satisfied smile, he captured the image. But as he turned to head back to his bike, his foot slipped on the loose gravel. It all happened in a blur—one moment he was steady, the next he was tumbling, the world spinning around him. Desperately, Alex reached out, his hand instinctively breaking his fall, only to cry out in pain as a sharp jolt ran up his arm.
When he finally stopped rolling, he was thankfully still on the roadside, just a few feet from where he'd stood. With his heart pounding in his chest and pain radiating from his wrist, he realized he'd been incredibly lucky. Bruised and scraped, he struggled to sit up, cradling his injured wrist.
A passing car soon stopped, and a concerned driver offered assistance, helping Alex back to his feet and ensuring he got the medical help he needed. At the hospital, the doctor confirmed what Alex already suspected—a broken wrist. It would be weeks before he could ride again, but he knew it could have been much worse.
As he sat in the hospital bed, his mind returned to the image he'd captured just moments before the fall—a perfect scene of nature’s grandeur and his own fleeting vulnerability. It was a reminder of the precarious balance between beauty and danger, a lesson he'd carry with him long after the cast came off his wrist.

2025-04-28 10:10:55Spam is the single biggest problem in decentralized networks. Jameson Lopp, co-founder of Casa and OG bitcoiner, has written a brilliant article on the death of decentralized email that paints a vivid picture of what went wrong—and how an originally decentralized protocol was completely captured. The cause? Spam.
The same fate may happen to Nostr, because posting a note is fundamentally cheap. Payments, and to some extent Proof of Work, certainly have their role in fighting spam, but they introduce friction, which doesn’t work everywhere. In particular, they can’t solve every economic problem.\ Take free trials, for example. There is a reason why 99% of companies offer them. Sure, you waste resources on users who don’t convert, but it’s a calculated cost, a marketing expense. Also, some services can’t or don’t want to monetize directly. They offer something for free and monetize elsewhere.
So how do you offer a free trial or giveaway in a hostile decentralized network? Or even, how do you decide which notes to accept on your relay?
At first glance, these may seem like unrelated questions—but they’re not. Generally speaking, these are situations where you have a finite budget, and you want to use it well. You want more of what you value — and less of what you don’t (spam).
Reputation is a powerful shortcut when direct evaluation isn’t practical. It’s hard to earn, easy to lose — and that’s exactly what makes it valuable.\ Can a reputable user do bad things? Absolutely. But it’s much less likely, and that’s the point. Heuristics are always imperfect, just like the world we live in.
The legacy Web relies heavily on email-based reputation. If you’ve ever tried to log in with a temporary email, you know what I’m talking about. It just doesn’t work anymore. The problem, as Lopp explains, is that these systems are highly centralized, opaque, and require constant manual intervention.\ They also suck. They put annoying roadblocks between the world and your product, often frustrating the very users you’re trying to convert.
At Vertex, we take a different approach.\ We transparently analyze Nostr’s open social graph to help companies fight spam while improving the UX for their users. But we don’t take away your agency—we just do the math. You take the decision of what algorithm and criteria to use.
Think of us as a signal provider, not an authority.\ You define what reputation means for your use case. Want to rank by global influence? Local or personalized? You’re in control. We give you actionable and transparent analytics so you can build sharper filters, better user experiences, and more resilient systems. That’s how we fight spam, without sacrificing decentralization.

2025-04-12 21:34:24What follows began as snippets of conversations I have been having for years, on and off, here and there. It will likely eventually be collated into a piece I have been meaning to write on “payments” as a whole. I foolishly started writing this piece years ago, not realizing that the topic is gargantuan and for every week I spend writing it I have to add two weeks to my plan. That may or may not ever come to fruition, but in the meantime, Tether announced it was issuing on Taproot Assets and suddenly everybody is interested again. This is as good a catalyst as any to carve out my “stablecoin thesis”, such as it exists, from “payments”, and put it out there for comment and feedback.
In contrast to the “Bitcoiner take” I will shortly revert to, I invite the reader to keep the following potential counterargument in mind, which might variously be termed the “shitcoiner”, “realist”, or “cynical” take, depending on your perspective: that stablecoins have clear product-market-fit. Now, as a venture capitalist and professional thinkboi focusing on companies building on Bitcoin, I obviously think that not only is Bitcoin the best money ever invented and its monetization is pretty much inevitable, but that, furthermore, there is enormous, era-defining long-term potential for a range of industries in which Bitcoin is emerging as superior technology, even aside from its role as money. But in the interest not just of steelmanning but frankly just of honesty, I would grudgingly agree with the following assessment as of the time of writing: the applications of crypto (inclusive of Bitcoin but deliberately wider) that have found product-market-fit today, and that are not speculative bets on future development and adoption, are: Bitcoin as savings technology, mining as a means of monetizing energy production, and stablecoins.
I think there are two typical Bitcoiner objections to stablecoins of significantly greater importance than all others: that you shouldn’t be supporting dollar hegemony, and that you don’t need a blockchain. I will elaborate on each of these, and for the remainder of the post will aim to produce a synthesis of three superficially contrasting (or at least not obviously related) sources of inspiration: these objections, the realisation above that stablecoins just are useful, and some commentary on technical developments in Bitcoin and the broader space that I think inform where things are likely to go. As will become clear as the argument progresses, I actually think the outcome to which I am building up is where things have to go. I think the technical and economic incentives at play make this an inevitability rather than a “choice”, per se. Given my conclusion, which I will hold back for the time being, this is a fantastically good thing, hence I am motivated to write this post at all!
Objection 1: Dollar Hegemony
I list this objection first because there isn’t a huge amount to say about it. It is clearly a normative position, and while I more or less support it personally, I don’t think that it is material to the argument I am going on to make, so I don’t want to force it on the reader. While the case for this objection is probably obvious to this audience (isn’t the point of Bitcoin to destroy central banks, not further empower them?) I should at least offer the steelman that there is a link between this and the realist observation that stablecoins are useful. The reason they are useful is because people prefer the dollar to even shitter local fiat currencies. I don’t think it is particularly fruitful to say that they shouldn’t. They do. Facts don’t care about your feelings. There is a softer bridging argument to be made here too, to the effect that stablecoins warm up their users to the concept of digital bearer (ish) assets, even though these particular assets are significantly scammier than Bitcoin. Again, I am just floating this, not telling the reader they should or shouldn’t buy into it.
All that said, there is one argument I do want to put my own weight behind, rather than just float: stablecoin issuance is a speculative attack on the institution of fractional reserve banking. A “dollar” Alice moves from JPMorgan to Tether embodies two trade-offs from Alice’s perspective: i) a somewhat opaque profile on the credit risk of the asset: the likelihood of JPMorgan ever really defaulting on deposits vs the operator risk of Tether losing full backing and/or being wrench attacked by the Federal Government and rugging its users. These risks are real but are almost entirely political. I’m skeptical it is meaningful to quantify them, but even if it is, I am not the person to try to do it. Also, more transparently to Alice, ii) far superior payment rails (for now, more on this to follow).
However, from the perspective of the fiat banking cartel, fractional reserve leverage has been squeezed. There are just as many notional dollars in circulation, but there the backing has been shifted from levered to unlevered issuers. There are gradations of relevant objections to this: while one might say, Tether’s backing comes from Treasuries, so you are directly funding US debt issuance!, this is a bit silly in the context of what other dollars one might hold. It’s not like JPMorgan is really competing with the Treasury to sell credit into the open market. Optically they are, but this is the core of the fiat scam. Via the guarantees of the Federal Reserve System, JPMorgan can sell as much unbacked credit as it wants knowing full well the difference will be printed whenever this blows up. Short-term Treasuries are also JPMorgan’s most pristine asset safeguarding its equity, so the only real difference is that Tether only holds Treasuries without wishing more leverage into existence. The realization this all builds up to is that, by necessity,
Tether is a fully reserved bank issuing fiduciary media against the only dollar-denominated asset in existence whose value (in dollar terms) can be guaranteed. Furthermore, this media arguably has superior “moneyness” to the obvious competition in the form of US commercial bank deposits by virtue of its payment rails.
That sounds pretty great when you put it that way! Of course, the second sentence immediately leads to the second objection, and lets the argument start to pick up steam …
Objection 2: You Don’t Need a Blockchain
I don’t need to explain this to this audience but to recap as briefly as I can manage: Bitcoin’s value is entirely endogenous. Every aspect of “a blockchain” that, out of context, would be an insanely inefficient or redundant modification of a “database”, in context is geared towards the sole end of enabling the stability of this endogenous value. Historically, there have been two variations of stupidity that follow a failure to grok this: i) “utility tokens”, or blockchains with native tokens for something other than money. I would recommend anybody wanting a deeper dive on the inherent nonsense of a utility token to read Only The Strong Survive, in particular Chapter 2, Crypto Is Not Decentralized, and the subsection, Everything Fights For Liquidity, and/or Green Eggs And Ham, in particular Part II, Decentralized Finance, Technically. ii) “real world assets” or, creating tokens within a blockchain’s data structure that are not intended to have endogenous value but to act as digital quasi-bearer certificates to some or other asset of value exogenous to this system. Stablecoins are in this second category.
RWA tokens definitionally have to have issuers, meaning some entity that, in the real world, custodies or physically manages both the asset and the record-keeping scheme for the asset. “The blockchain” is at best a secondary ledger to outsource ledger updates to public infrastructure such that the issuer itself doesn’t need to bother and can just “check the ledger” whenever operationally relevant. But clearly ownership cannot be enforced in an analogous way to Bitcoin, under both technical and social considerations. Technically, Bitcoin’s endogenous value means that whoever holds the keys to some or other UTXOs functionally is the owner. Somebody else claiming to be the owner is yelling at clouds. Whereas, socially, RWA issuers enter a contract with holders (whether legally or just in terms of a common-sense interpretation of the transaction) such that ownership of the asset issued against is entirely open to dispute. That somebody can point to “ownership” of the token may or may not mean anything substantive with respect to the physical reality of control of the asset, and how the issuer feels about it all.
And so, one wonders, why use a blockchain at all? Why doesn’t the issuer just run its own database (for the sake of argument with some or other signature scheme for verifying and auditing transactions) given it has the final say over issuance and redemption anyway? I hinted at an answer above: issuing on a blockchain outsources this task to public infrastructure. This is where things get interesting. While it is technically true, given the above few paragraphs, that, you don’t need a blockchain for that, you also don’t need to not use a blockchain for that. If you want to, you can.
This is clearly the case given stablecoins exist at all and have gone this route. If one gets too angry about not needing a blockchain for that, one equally risks yelling at clouds! And, in fact, one can make an even stronger argument, more so from the end users’ perspective. These products do not exist in a vacuum but rather compete with alternatives. In the case of stablecoins, the alternative is traditional fiat money, which, as stupid as RWAs on a blockchain are, is even dumber. It actually is just a database, except it’s a database that is extremely annoying to use, basically for political reasons because the industry managing these private databases form a cartel that never needs to innovate or really give a shit about its customers at all. In many, many cases, stablecoins on blockchains are dumb in the abstract, but superior to the alternative methods of holding and transacting in dollars existing in other forms. And note, this is only from Alice’s perspective of wanting to send and receive, not a rehashing of the fractional reserve argument given above. This is the essence of their product-market-fit. Yell at clouds all you like: they just are useful given the alternative usually is not Bitcoin, it’s JPMorgan’s KYC’d-up-the-wazoo 90s-era website, more than likely from an even less solvent bank.
So where does this get us? It might seem like we are back to “product-market-fit, sorry about that” with Bitcoiners yelling about feelings while everybody else makes do with their facts. However, I think we have introduced enough material to move the argument forward by incrementally incorporating the following observations, all of which I will shortly go into in more detail: i) as a consequence of making no technical sense with respect to what blockchains are for, today’s approach won’t scale; ii) as a consequence of short-termist tradeoffs around socializing costs, today’s approach creates an extremely unhealthy and arguably unnatural market dynamic in the issuer space; iii) Taproot Assets now exist and handily address both points i) and ii), and; iv) eCash is making strides that I believe will eventually replace even Taproot Assets.
To tease where all this is going, and to get the reader excited before we dive into much more detail: just as Bitcoin will eat all monetary premia, Lightning will likely eat all settlement, meaning all payments will gravitate towards routing over Lightning regardless of the denomination of the currency at the edges. Fiat payments will gravitate to stablecoins to take advantage of this; stablecoins will gravitate to TA and then to eCash, and all of this will accelerate hyperbitcoinization by “bitcoinizing” payment rails such that an eventual full transition becomes as simple as flicking a switch as to what denomination you want to receive.
I will make two important caveats before diving in that are more easily understood in light of having laid this groundwork: I am open to the idea that it won’t be just Lightning or just Taproot Assets playing the above roles. Without veering into forecasting the entire future development of Bitcoin tech, I will highlight that all that really matters here are, respectively: a true layer 2 with native hashlocks, and a token issuance scheme that enables atomic routing over such a layer 2 (or combination of such). For the sake of argument, the reader is welcome to swap in “Ark” and “RGB” for “Lightning” and “TA” both above and in all that follows. As far as I can tell, this makes no difference to the argument and is even exciting in its own right. However, for the sake of simplicity in presentation, I will stick to “Lightning” and “TA” hereafter.
1) Today’s Approach to Stablecoins Won’t Scale
This is the easiest to tick off and again doesn’t require much explanation to this audience. Blockchains fundamentally don’t scale, which is why Bitcoin’s UTXO scheme is a far better design than ex-Bitcoin Crypto’s’ account-based models, even entirely out of context of all the above criticisms. This is because Bitcoin transactions can be batched across time and across users with combinations of modes of spending restrictions that provide strong economic guarantees of correct eventual net settlement, if not perpetual deferral. One could argue this is a decent (if abstrusely technical) definition of “scaling” that is almost entirely lacking in Crypto.
What we see in ex-Bitcoin crypto is so-called “layer 2s” that are nothing of the sort, forcing stablecoin schemes in these environments into one of two equally poor design choices if usage is ever to increase: fees go higher and higher, to the point of economic unviability (and well past it) as blocks fill up, or move to much more centralized environments that increasingly are just databases, and hence which lose the benefits of openness thought to be gleaned by outsourcing settlement to public infrastructure. This could be in the form of punting issuance to a bullshit “layer 2” that is a really a multisig “backing” a private execution environment (to be decentralized any daw now) or an entirely different blockchain that is just pretending even less not to be a database to begin with. In a nutshell, this is a decent bottom-up explanation as to why Tron has the highest settlement of Tether.
This also gives rise to the weirdness of “gas tokens” - assets whose utility as money is and only is in the form of a transaction fee to transact a different kind of money. These are not quite as stupid as a “utility token,” given at least they are clearly fulfilling a monetary role and hence their artificial scarcity can be justified. But they are frustrating from Bitcoiners’ and users’ perspectives alike: users would prefer to pay transaction fees on dollars in dollars, but they can’t because the value of Ether, Sol, Tron, or whatever, is the string and bubblegum that hold their boondoggles together. And Bitcoiners wish this stuff would just go away and stop distracting people, whereas this string and bubblegum is proving transiently useful.
All in all, today’s approach is fine so long as it isn’t being used much. It has product-market fit, sure, but in the unenviable circumstance that, if it really starts to take off, it will break, and even the original users will find it unusable.
2) Today’s Approach to Stablecoins Creates an Untenable Market Dynamic
Reviving the ethos of you don’t need a blockchain for that, notice the following subtlety: while the tokens representing stablecoins have value to users, that value is not native to the blockchain on which they are issued. Tether can (and routinely does) burn tokens on Ethereum and mint them on Tron, then burn on Tron and mint on Solana, and so on. So-called blockchains “go down” and nobody really cares. This makes no difference whatsoever to Tether’s own accounting, and arguably a positive difference to users given these actions track market demand. But it is detrimental to the blockchain being switched away from by stripping it of “TVL” that, it turns out, was only using it as rails: entirely exogenous value that leaves as quickly as it arrived.
One underdiscussed and underappreciated implication of the fact that no value is natively running through the blockchain itself is that, in the current scheme, both the sender and receiver of a stablecoin have to trust the same issuer. This creates an extremely powerful network effect that, in theory, makes the first-to-market likely to dominate and in practice has played out exactly as this theory would suggest: Tether has roughly 80% of the issuance, while roughly 19% goes to the political carve-out of USDC that wouldn’t exist at all were it not for government interference. Everybody else combined makes up the final 1%.
So, Tether is a full reserve bank but also has to be everybody’s bank. This is the source of a lot of the discomfort with Tether, and which feeds into the original objection around dollar hegemony, that there is an ill-defined but nonetheless uneasy feeling that Tether is slowly morphing into a CBDC. I would argue this really has nothing to do with Tether’s own behavior but rather is a consequence of the market dynamic inevitably created by the current stablecoin scheme. There is no reason to trust any other bank because nobody really wants a bank, they just want the rails. They want something that will retain a nominal dollar value long enough to spend it again. They don’t care what tech it runs on and they don’t even really care about the issuer except insofar as having some sense they won’t get rugged.
Notice this is not how fiat works. Banks can, of course, settle between each other, thus enabling their users to send money to customers of other banks. This settlement function is actually the entire point of central banks, less the money printing and general corruption enabled (we might say, this was the historical point of central banks, which have since become irredeemably corrupted by this power). This process is clunkier than stablecoins, as covered above, but the very possibility of settlement means there is no gigantic network effect to being the first commercial issuer of dollar balances. If it isn’t too triggering to this audience, one might suggest that the money printer also removes the residual concern that your balances might get rugged! (or, we might again say, you guarantee you don’t get rugged in the short term by guaranteeing you do get rugged in the long term).
This is a good point at which to introduce the unsettling observation that broader fintech is catching on to the benefits of stablecoins without any awareness whatsoever of all the limitations I am outlining here. With the likes of Stripe, Wise, Robinhood, and, post-Trump, even many US megabanks supposedly contemplating issuing stablecoins (obviously within the current scheme, not the scheme I am building up to proposing), we are forced to boggle our minds considering how on earth settlement is going to work. Are they going to settle through Ether? Well, no, because i) Ether isn’t money, it’s … to be honest, I don’t think anybody really knows what it is supposed to be, or if they once did they aren’t pretending anymore, but anyway, Stripe certainly hasn’t figured that out yet so, ii) it won’t be possible to issue them on layer 1s as soon as there is any meaningful volume, meaning they will have to route through “bullshit layer 2 wrapped Ether token that is really already a kind of stablecoin for Ether.”
The way they are going to try to fix this (anybody wanna bet?) is routing through DEXes, which is so painfully dumb you should be laughing and, if you aren’t, I would humbly suggest you don’t get just how dumb it is. What this amounts to is plugging the gap of Ether’s lack of moneyness (and wrapped Ether’s hilarious lack of moneyness) with … drum roll … unknowable technical and counterparty risk and unpredictable cost on top of reverting to just being a database. So, in other words, all of the costs of using a blockchain when you don’t strictly need to, and none of the benefits. Stripe is going to waste billions of dollars getting sandwich attacked out of some utterly vanilla FX settlement it is facilitating for clients who have even less of an idea what is going on and why North Korea now has all their money, and will eventually realize they should have skipped their shitcoin phase and gone straight to understanding Bitcoin instead …
3) Bitcoin (and Taproot Assets) Fixes This
To tie together a few loose ends, I only threw in the hilariously stupid suggestion of settling through wrapped Ether on Ether on Ether in order to tee up the entirely sensible suggestion of settling through Lightning. Again, not that this will be new to this audience, but while issuance schemes have been around on Bitcoin for a long time, the breakthrough of Taproot Assets is essentially the ability to atomically route through Lightning.
I will admit upfront that this presents a massive bootstrapping challenge relative to the ex-Bitcoin Crypto approach, and it’s not obvious to me if or how this will be overcome. I include this caveat to make it clear I am not suggesting this is a given. It may not be, it’s just beyond the scope of this post (or frankly my ability) to predict. This is a problem for Lightning Labs, Tether, and whoever else decides to step up to issue. But even highlighting this as an obvious and major concern invites us to consider an intriguing contrast: scaling TA stablecoins is hardest at the start and gets easier and easier thereafter. The more edge liquidity there is in TA stables, the less of a risk it is for incremental issuance; the more TA activity, the more attractive deploying liquidity is into Lightning proper, and vice versa. With apologies if this metaphor is even more confusing than it is helpful, one might conceive of the situation as being that there is massive inertia to bootstrap, but equally there could be positive feedback in driving the inertia to scale. Again, I have no idea, and it hasn’t happened yet in practice, but in theory it’s fun.
More importantly to this conversation, however, this is almost exactly the opposite dynamic to the current scheme on other blockchains, which is basically free to start, but gets more and more expensive the more people try to use it. One might say it antiscales (I don’t think that’s a real word, but if Taleb can do it, then I can do it too!).
Furthermore, the entire concept of “settling in Bitcoin” makes perfect sense both economically and technically: economically because Bitcoin is money, and technically because it can be locked in an HTLC and hence can enable atomic routing (i.e. because Lightning is a thing). This is clearly better than wrapped Eth on Eth on Eth or whatever, but, tantalisingly, is better than fiat too! The core message of the payments tome I may or may not one day write is (or will be) that fiat payments, while superficially efficient on the basis of centralized and hence costless ledger amendments, actually have a hidden cost in the form of interbank credit. Many readers will likely have heard me say this multiple times and in multiple settings but, contrary to popular belief, there is no such thing as a fiat debit. Even if styled as a debit, all fiat payments are credits and all have credit risk baked into their cost, even if that is obscured and pushed to the absolute foundational level of money printing to keep banks solvent and hence keep payment channels open.
Furthermore! this enables us to strip away the untenable market dynamic from the point above. The underappreciated and underdiscussed flip side of the drawback of the current dynamic that is effectively fixed by Taproot Assets is that there is no longer a mammoth network effect to a single issuer. Senders and receivers can trust different issuers (i.e. their own banks) because those banks can atomically settle a single payment over Lightning. This does not involve credit. It is arguably the only true debit in the world across both the relevant economic and technical criteria: it routes through money with no innate credit risk, and it does so atomically due to that money’s native properties.
Savvy readers may have picked up on a seed I planted a while back and which can now delightfully blossom:
This is what Visa was supposed to be!
Crucially, this is not what Visa is now. Visa today is pretty much the bank that is everybody’s counterparty, takes a small credit risk for the privilege, and oozes free cash flow bottlenecking global consumer payments.
But if you read both One From Many by Dee Hock (for a first person but pretty wild and extravagant take) and Electronic Value Exchange by David Stearns (for a third person, drier, but more analytical and historically contextualized take) or if you are just intimately familiar with the modern history of payments for whatever other reason, you will see that the role I just described for Lightning in an environment of unboundedly many banks issuing fiduciary media in the form of stablecoins is exactly what Dee Hock wanted to create when he envisioned Visa:
A neutral and open layer of value settlement enabling banks to create digital, interbank payment schemes for their customers at very low cost.
As it turns out, his vision was technically impossible with fiat, hence Visa, which started as a cooperative amongst member banks, was corrupted into a duopolistic for-profit rent seeker in curious parallel to the historical path of central banks …
4) eCash
To now push the argument to what I think is its inevitable conclusion, it’s worth being even more vigilant on the front of you don’t need a blockchain for that. I have argued that there is a role for a blockchain in providing a neutral settlement layer to enable true debits of stablecoins. But note this is just a fancy and/or stupid way of saying that Bitcoin is both the best money and is programmable, which we all knew anyway. The final step is realizing that, while TA is nice in terms of providing a kind of “on ramp” for global payments infrastructure as a whole to reorient around Lightning, there is some path dependence here in assuming (almost certainly correctly) that the familiarity of stablecoins as “RWA tokens on a blockchain” will be an important part of the lure.
But once that transition is complete, or is well on its way to being irreversible, we may as well come full circle and cut out tokens altogether. Again, you really don’t need a blockchain for that, and the residual appeal of better rails has been taken care of with the above massive detour through what I deem to be the inevitability of Lightning as a settlement layer. Just as USDT on Tron arguably has better moneyness than a JPMorgan balance, so a “stablecoin” as eCash has better moneyness than as a TA given it is cheaper, more private, and has more relevantly bearer properties (in other words, because it is cash). The technical detail that it can be hashlocked is really all you need to tie this all together. That means it can be atomically locked into a Lightning routed debit to the recipient of a different issuer (or “mint” in eCash lingo, but note this means the same thing as what we have been calling fully reserved banks). And the economic incentive is pretty compelling too because, for all their benefits, there is still a cost to TAs given they are issued onchain and they require asset-specific liquidity to route on Lightning. Once the rest of the tech is in place, why bother? Keep your Lightning connectivity and just become a mint.
What you get at that point is dramatically superior private database to JPMorgan with the dramatically superior public rails of Lightning. There is nothing left to desire from “a blockchain” besides what Bitcoin is fundamentally for in the first place: counterparty-risk-free value settlement.
And as a final point with a curious and pleasing echo to Dee Hock at Visa, Calle has made the point repeatedly that David Chaum’s vision for eCash, while deeply philosophical besides the technical details, was actually pretty much impossible to operate on fiat. From an eCash perspective, fiat stablecoins within the above infrastructure setup are a dramatic improvement on anything previously possible. But, of course, they are a slippery slope to Bitcoin regardless …
Objections Revisited
As a cherry on top, I think the objections I highlighted at the outset are now readily addressed – to the extent the reader believes what I am suggesting is more or less a technical and economic inevitability, that is. While, sure, I’m not particularly keen on giving the Treasury more avenues to sell its welfare-warfare shitcoin, on balance the likely development I’ve outlined is an enormous net positive: it’s going to sell these anyway so I prefer a strong economic incentive to steadily transition not only to Lightning as payment rails but eCash as fiduciary media, and to use “fintech” as a carrot to induce a slow motion bank run.
As alluded to above, once all this is in place, the final step to a Bitcoin standard becomes as simple as an individual’s decision to want Bitcoin instead of fiat. On reflection, this is arguably the easiest part! It's setting up all the tech that puts people off, so trojan-horsing them with “faster, cheaper payment rails” seems like a genius long-term strategy.
And as to “needing a blockchain” (or not), I hope that is entirely wrapped up at this point. The only blockchain you need is Bitcoin, but to the extent people are still confused by this (which I think will take decades more to fully unwind), we may as well lean into dazzling them with whatever innovation buzzwords and decentralization theatre they were going to fall for anyway before realizing they wanted Bitcoin all along.
Conclusion
Stablecoins are useful whether you like it or not. They are stupid in the abstract but it turns out fiat is even stupider, on inspection. But you don’t need a blockchain, and using one as decentralization theatre creates technical debt that is insurmountable in the long run. Blockchain-based stablecoins are doomed to a utility inversely proportional to their usage, and just to rub it in, their ill-conceived design practically creates a commercial dynamic that mandates there only ever be a single issuer.
Given they are useful, it seems natural that this tension is going to blow up at some point. It also seems worthwhile observing that Taproot Asset stablecoins have almost the inverse problem and opposite commercial dynamic: they will be most expensive to use at the outset but get cheaper and cheaper as their usage grows. Also, there is no incentive towards a monopoly issuer but rather towards as many as are willing to try to operate well and provide value to their users.
As such, we can expect any sizable growth in stablecoins to migrate to TA out of technical and economic necessity. Once this has happened - or possibly while it is happening but is clearly not going to stop - we may as well strip out the TA component and just use eCash because you really don’t need a blockchain for that at all. And once all the money is on eCash, deciding you want to denominate it in Bitcoin is the simplest on-ramp to hyperbitcoinization you can possibly imagine, given we’ve spent the previous decade or two rebuilding all payments tech around Lightning.
Or: Bitcoin fixes this. The End.

Nos complace presentar a nuestro público lector la obra China y el regreso de Confucio, un compilación de artículos llevada a cabo por prestigioso profesor Carlos X Blanco, autor prolífico y colaborador de Hipérbola Janus, donde nos sentimos honrados y gratificados por sus aportaciones en la difusión de diferentes temas y áreas de conocimiento. En el caso que nos ocupa, el Extremo Oriente sigue siendo un gran desconocido para nosotros, los europeos, especialmente en cuestiones relacionadas con la mentalidad y las ideas que animan la cosmovisión de su nación más representativa, cuya pujanza económica, comercial y geopolítica ha encumbrado a la categoría de superpotencia mundial, hablamos, obviamente, de China. A través de un formato ligero y agradable, como es el diálogo, la obra nos presenta una serie de textos que nos permiten desentrañar las claves del pensamiento confuciano y su desarrollo a lo largo de los siglos XX y XXI. Un breve prólogo a cargo de David Ownby sirve de introducción a la obra. Uno de los ensayos principales es «Un siglo de confucianismo» de Chen Lai (1952), quien estructura el análisis en tres grandes secciones: los desafíos del confucianismo, sus respuestas y las formas en que ha sobrevivido en la era moderna.
En el análisis del Confucianismo, que permanece fuertemente imbricado en la conciencia del pueblo chino, se abordan cuatro grandes desafíos que enumeramos a continuación:
- Reformas políticas y educativas en la era Qing y Republicana (1901-1912): La abolición del sistema de exámenes imperiales debilitó la base institucional del confucianismo, afectando su papel en la sociedad y la educación.
- Movimiento de la Nueva Cultura (1915-1919): Se promovió la modernización basada en la cultura occidental, posicionando al confucianismo como un obstáculo para el progreso.
- Revolución de 1949 y la Revolución Cultural (1966-1976): La colectivización y las comunas populares destruyeron la base social confuciana, mientras que la Revolución Cultural lo atacó ideológicamente.
- Reformas de Deng Xiaoping (1978 en adelante): La modernización y la economía de mercado redujeron la influencia de los valores confucianos frente al pragmatismo y el utilitarismo.
Con anterioridad, el confucianismo siempre ha sido un factor de cohesión nacional, que ha contribuido a preservar la unidad del pueblo chino, especialmente contra las amenazas exteriores, como la que representó el enfrentamiento con Japón desde comienzos de los años 30 del pasado siglo, con la ocupación japonesa de Manchuria, y los sucesivos episodios bélicos vividos contra Japón entre 1937 y 1942.

El texto de Chen Lai toma como punto de partida los últimos años de la Dinastía Qing y los primeros años de la era republicana, entre 1901 y 1912, poniendo especial énfasis en el proceso de modernización emprendido durante esta época, con la introducción de las ciencias y las disciplinas occidentales, hecho que contribuyó a la condena al ostracismo de los clásicos confucianos. Este proceso conoce diversas etapas, a través de las cuales se procede a la abolición del sistema de exámenes imperiales, que durante años se había erigido como el pilar institucional del confucianismo, lo cual trajo como consecuencia inevitable que los eruditos confucianos abandonaran su papel central en la sociedad china. La tendencia a denostar la tradición confuciana se vio incrementada con la transición de la Dinastía de los Qing a los primeros años de la República, como demuestra la eliminación de las ceremonias sacrificiales en honor a Confucio y la prohibición del estudio obligatorio de los clásicos confucianos. De esta manera el confucianismo perdió su papel preponderante en la educación y la administración pública, quedando relegado al ámbito de la ética y la cultura.
Este proceso de rechazo y erosión del confucianismo en su papel de contribución a la identidad nacional china, y a la formación de las nuevas generaciones, se vio acelerado durante las siguientes décadas. Fue un proceso impulsado por intelectuales como Chen Duxiu y Hu Shih, que promovieron activamente la modernización junto con la asunción de valores occidentales como la ciencia o la democracia. Asumiendo posturas análogas a las occidentales en relación a la Tradición, se vio en el confucianismo una forma de pensamiento retrógrado y caduco, frontalmente opuesto al progreso, y por tanto desechable, respecto al cual sus enseñanzas carecían de todo valor operativo en el desarrollo de China. En consecuencia, el confucianismo vivió un ostracismo cultural e intelectual que lo sumió en la más absoluta marginalidad.
Con el advenimiento de la Revolución Cultural China y la conformación del régimen comunista, a partir de 1949 y hasta la muerte de Mao Tse Tung (1893-1976), la situación del confucianismo no mejoró y, muy al contrario, se consideró incompatible con el socialismo marxista. Los ataques se incrementaron y el confucianismo fue objeto de campañas de odio brutales, como aquella desarrollada entre 1973 y 1976, con la «Crítica a Lin Biao y Confucio», en la que se le acusó de «ideología feudal y reaccionaria». La destrucción de templos confucianos y la persecución de sus intelectuales fue un hecho habitual durante este periodo.

En el periodo inmediatamente posterior, a partir de 1978, el factor ideológico se vio atenuado con la llegada de Deng Xiaoping (1904-1997) al poder, y se impuso una época marcada por el pragmatismo y la importancia creciente del desarrollo económico y material. Los ataques al confucianismo cesaron en gran medida, pero se vio sometido a la lógica uniformizadora del utilitarismo y el crecimiento económico.
No obstante, y a pesar de los ataques continuos de los que fue objeto, Chen Lai pone de relieve la resistencia del confucianismo, su voluntad irreductible frente a la amenaza de desaparición, a través de las propuestas de diferentes pensadores confucianos contemporáneos. Es el caso, por ejemplo, de Kang Youwei (1858-1927) con sus propuestas de convertir el confucianismo en religión oficial o integrarlo en el modelo educativo con sus enseñanzas morales sobre el conjunto del pueblo chino. Otros filósofos, como Liang Shuming (1893-1988), trató de superar las antítesis del mundo moderno, y convertir la doctrina de Confucio en parte funcional del socialismo a través de su base moral y social, dado que veía en estas ideas la clave para lograr la armonía y la estabilidad social, tal y como lo había sido en los momentos más delicados de la historia del país asiático.
Paralelamente, intelectuales confucianos como Xiong Shili (1885-1968), Feng Youlan (1895-1990) y He Lin (1902-1992) trataron de aportar nuevos desarrollos a la doctrina confuciana en el terreno de la filosofía y la metafísica. Fruto de estas especulaciones surgieron nuevas escuelas como la «Nueva Filosofía del Principio» de Feng Youlan y la «Nueva Filosofía de la Mente» de He Lin. Tampoco faltaron nuevos intentos de integración entre los valores tradicionales y el socialismo marxista a través de las interpretaciones de Xiong Shili. No será hasta una etapa posterior a la toma del poder de Den Xiaoping que veremos revalorizarse el confucianismo, sometiéndose a un revisionismo que finalmente lo devuelve a las universidades y la sociedad china, momento a partir del cual se recupera su legado como parte de la identidad nacional.
Este proceso de revitalización ha contribuido al estudio del confucianismo y a la aparición de nuevas interpretaciones en las últimas décadas. Las reinterpretaciones del pensamiento confuciano han llevado a la doctrina a un contraste con ideas político-ideológicas del mundo actual, relacionadas con la «democracia», los «derechos humanos» y la «globalización», es decir, con aquellos ítems ideológicos que padecemos en los tiempos postreros, y que están impulsando cambios dramáticos en nuestras sociedades en estos mismos momentos. No obstante, esta recuperación del confucianismo no se ha limitado a las esferas más cultas y académicas, sino que también se ha popularizado, y su presencia en la sociedad china viene siendo cada vez mayor desde la década de los 90, como vemos a través del conocimiento de los clásicos confucianos a través de actividades y cursos dirigidos a la población en general.
De modo que, para Chen Lai, el momento actual, tras la rehabilitación del pensamiento confuciano, es clave para continuar fortaleciendo su doctrina, especialmente por el ascenso de China como potencia mundial, que ha conllevado un creciente interés de China y su cultura más allá de sus fronteras. Pero también, y más allá de aspectos generales y más formales, por el propio contenido ético y moral que le es inherente, y que puede actuar como un freno frente a la corrupción y degradación de los tiempos modernos. De manera que podemos afirmar que es posible una verdadera sinergia entre los valores tradicionales y los nuevos desafíos que la modernidad propone a China, en un frente amplio, en el terreno cultural, político, social etc.
En el segundo capítulo del libro Chen Ming, una de las figuras más importantes del resurgimiento del confucianismo en la China contemporánea aborda la trascendencia de susodicha doctrina en el contexto del Estado y la nación china del siglo XXI. Su enfoque nos proporciona un recorrido a lo largo de aspectos políticos, sociales, educativos, de identidad cultural y la religión, marcando diferencias respecto a otras perspectivas neoconfucianas más orientadas hacia la filosofía o la ética.
Y es que el neoconfucianismo fuera de las fronteras chinas ha diversificado sus corrientes y los temas tratados, y se han centrado en la relación con la democracia, la ciencia y, en definitiva, con su compatibilidad con los valores del liberalismo occidental. Temas que no son nuevos en las derivas interpretativas y especulaciones confucianas del pasado siglo. Un representante destacado de estas últimas posturas es Tu Weiming (1940), filósofo de origen chino nacionalizado estadounidense.
Dentro de la China continental, el discurso confuciano se ha mostrado plenamente funcional a los intereses del Estado chino, contribuyendo a la cimentación de los valores estatales y nacionales, desmarcándose de toda búsqueda de compatibilidad con los valores occidentales, y en su detrimento tratando de fortalecer la identidad cultural china postulándose abiertamente como un pilar fundamental del nacionalismo cultural y político del país asiático. De modo que Chen Ming no ve en la doctrina confuciana un conjunto de ideas abstractas y anacrónicas, sino un potencial en ciernes para seguir pertrechando las bases del Estado y la sociedad china en el mundo actual.
También es importante el análisis que hace del confucianismo frente a la religión, diferenciando sus elementos de toda forma de religión monoteísta, tal y como la concebimos en el «Occidente». No obstante, hay un elemento religioso en su origen, y la idea de un Dios (Shangdi o Tian) como creador y vertebrador de un orden moral. Se puede decir que Confucio transformó este pensamiento en una práctica basada en la ética y la virtud, pero sin eliminar su dimensión espiritual. Algunos intérpretes modernos de la doctrina han tratado de desvirtuar su contenido reduciéndolo a lo que en chino se conoce como «wenjiao» (enseñanza cultural), buscando una fórmula de secularización para despojarla de ese contenido trascendente. Según Chen Ming estos intentos de secularización fueron perpetrados por el Movimiento 4 de mayo a partir de 1919.
No obstante, debemos insistir en que el confucianismo, aún poseyendo una dimensión espiritual, no debe confundirse con nuestro concepto de religión, y hay que poner el énfasis en la idea de estructura moral y social, como una especie de guía moral y espiritual que actúa como antídoto frente a la crisis de los valores tan característica de los tiempos modernos. El texto de Chen Ming también aborda otras problemáticas que no podemos desglosar en la presentación por su amplitud y complejidad, como, por ejemplo, las relaciones del confucianismo con el Estado, el ateísmo del Partido Comunista Chino, la búsqueda de formas de integración y síntesis, cohesión social, el problema de la educación etc. Hay una serie de retos que se presentan a las ideas de Confucio en las que esta búsqueda de encaje en la China contemporánea plantea una serie de desafíos que ponen en riesgo la esencia de su tradición.
El último capítulo del libro está reservado a una entrevista entre Chen Yizhong y Chen Ming en la que se abordan todos los temas que se han tratado en los capítulos anteriores, bajo el formato de un diálogo profundo. Asistimos al contraste de multitud de argumentos sobre el Confucianismo y su relación con la modernidad, con los retos del futuro, con las tensiones y recelos que suscitan los valores liberales y occidentales, totalmente secularizados y, esto lo decimos nosotros, abocados a la destrucción de cualquier fundamento tradicional, étnico o espiritual a todos los niveles.

Egal, ob Koalitionsverhandlungen oder politischer Alltag: Die Kontroversen zwischen theoretisch verschiedenen Parteien verschwinden, wenn es um den Kampf gegen politische Gegner mit Rückenwind geht. Wer den Alteingesessenen die Pfründe ernsthaft streitig machen könnte, gegen den werden nicht nur «Brandmauern» errichtet, sondern der wird notfalls auch strafrechtlich verfolgt. Doppelstandards sind dabei selbstverständlich inklusive.
In Frankreich ist diese Woche Marine Le Pen wegen der Veruntreuung von EU-Geldern von einem Gericht verurteilt worden. Als Teil der Strafe wurde sie für fünf Jahre vom passiven Wahlrecht ausgeschlossen. Obwohl das Urteil nicht rechtskräftig ist – Le Pen kann in Berufung gehen –, haben die Richter das Verbot, bei Wahlen anzutreten, mit sofortiger Wirkung verhängt. Die Vorsitzende des rechtsnationalen Rassemblement National (RN) galt als aussichtsreiche Kandidatin für die Präsidentschaftswahl 2027.
Das ist in diesem Jahr bereits der zweite gravierende Fall von Wahlbeeinflussung durch die Justiz in einem EU-Staat. In Rumänien hatte Călin Georgescu im November die erste Runde der Präsidentenwahl überraschend gewonnen. Das Ergebnis wurde später annulliert, die behauptete «russische Wahlmanipulation» konnte jedoch nicht bewiesen werden. Die Kandidatur für die Wahlwiederholung im Mai wurde Georgescu kürzlich durch das Verfassungsgericht untersagt.
Die Veruntreuung öffentlicher Gelder muss untersucht und geahndet werden, das steht außer Frage. Diese Anforderung darf nicht selektiv angewendet werden. Hingegen mussten wir in der Vergangenheit bei ungleich schwerwiegenderen Fällen von (mutmaßlichem) Missbrauch ganz andere Vorgehensweisen erleben, etwa im Fall der heutigen EZB-Chefin Christine Lagarde oder im «Pfizergate»-Skandal um die Präsidentin der EU-Kommission Ursula von der Leyen.
Wenngleich derartige Angelegenheiten formal auf einer rechtsstaatlichen Grundlage beruhen mögen, so bleibt ein bitterer Beigeschmack. Es stellt sich die Frage, ob und inwieweit die Justiz politisch instrumentalisiert wird. Dies ist umso interessanter, als die Gewaltenteilung einen essenziellen Teil jeder demokratischen Ordnung darstellt, während die Bekämpfung des politischen Gegners mit juristischen Mitteln gerade bei den am lautesten rufenden Verteidigern «unserer Demokratie» populär zu sein scheint.
Die Delegationen von CDU/CSU und SPD haben bei ihren Verhandlungen über eine Regierungskoalition genau solche Maßnahmen diskutiert. «Im Namen der Wahrheit und der Demokratie» möchte man noch härter gegen «Desinformation» vorgehen und dafür zum Beispiel den Digital Services Act der EU erweitern. Auch soll der Tatbestand der Volksverhetzung verschärft werden – und im Entzug des passiven Wahlrechts münden können. Auf europäischer Ebene würde Friedrich Merz wohl gerne Ungarn das Stimmrecht entziehen.
Der Pegel an Unzufriedenheit und Frustration wächst in großen Teilen der Bevölkerung kontinuierlich. Arroganz, Machtmissbrauch und immer abstrusere Ausreden für offensichtlich willkürliche Maßnahmen werden kaum verhindern, dass den etablierten Parteien die Unterstützung entschwindet. In Deutschland sind die Umfrageergebnisse der AfD ein guter Gradmesser dafür.

2025-04-02 12:12:12We value sovereignty, privacy and security when accessing online content, using several tools to achieve this, like open protocols, open OSes, open software products, Tor and VPNs.
The problem
Talking about our social presence, we can manually build up our follower list (social graph), pick a Nostr client that is respectful of our preferences on what to show and how, but with the standard following mechanism, our main feed is public, so everyone can actually snoop what we are interested in, and what is supposable that we read daily.
The solution
Nostr has a simple solution for this necessity: encrypted lists. Lists are what they appear, a collection of people or interests (but they can also group much other stuff, see NIP-51). So we can create lists with contacts that we don't have in our main social graph; these lists can be used primarily to create dedicated feeds, but they could have other uses, for example, related to monitoring. The interesting thing about lists is that they can also be encrypted, so unlike the basic following list, which is always public, we can hide the lists' content from others. The implications are obvious: we can not only have a more organized way to browse content, but it is also really private one.
One might wonder what use can really be made of private lists; here are some examples:
- Browse “can't miss” content from users I consider a priority;
- Supervise competitors or adversarial parts;
- Monitor sensible topics (tags);
- Following someone without being publicly associated with them, as this may be undesirable;
The benefits in terms of privacy as usual are not only related to the casual, or programmatic, observer, but are also evident when we think of how many bots scan our actions to profile us.
The current state
Unfortunately, lists are not widely supported by Nostr clients, and encrypted support is a rarity. Often the excuse to not implement them is that they are harder to develop, since they require managing the encryption stuff (NIP-44). Nevertheless, developers have an easier option to start offering private lists: give the user the possibility to simply mark them as local-only, and never push them to the relays. Even if the user misses the sync feature, this is sufficient to create a private environment.
To date, as far as I know, the best client with list management is Gossip, which permits to manage both encrypted and local-only lists.
Beg your Nostr client to implement private lists!

| |:-:| |LIPOVETSKY, Gilles; La era del vacío; Anagrama, 2006|
El libro que nos disponemos a reseñar hoy es enormemente complejo, y lo es en a medida que cuestiona elementos clave que ayudan a explicar desde el ámbito de la sociología y la filosofía una serie de cambios culturales, sociales y subjetivos en las sociedades occidentales desde mediados del siglo XX en adelante. La era del vacío: Ensayos sobre el individualismo contemporáneo fue publicada originalmente en el año 1983. Con un estilo ensayísticos y profundamente analítico Gilles Lipovetsky nos ofrece un análisis que trasciende los límites de la sociología clásica, al analizar fenómenos tan propios de nuestro tiempo como la subjetividad posmoderna, el hedonismo consumista y el declive de los grandes relatos ideológicos.
Este libro, que fue de una importancia capital en el momento de su publicación y durante la década de los años 80, se puede considerar como el primer intento de sistematizar la posmodernidad más allá de las teorías estéticas, centrándose en aspectos culturales y psicológicos cotidianos. Para Lipovetsky el mundo posmoderno está inmerso en una serie de procesos de mutación que pueden resultar ambiguos, así como tensiones, pero también con nuevas posibilidades.
|
| |:-:| |Gilles Lipovetsky (Millau, Francia, 1944)|
El autor parte de una premisa fundamental: y es que la modernidad ha dado paso a un nuevo estadio de la sociedad, el cual se caracteriza por la disolución de las grandes narrativas colectivas que antes daban sentido de conjunto a las vidas humanas. Frente a la racionalidad industrial, la ética del trabajo y la identidad colectiva que dominaban en los siglos precedentes, el individuo moderno encuentra ahora una posición de autonomía total y radical, pero, como contrapartida, también de vacío existencial. La sociedad de nuestros días, se mueve a un flujo de novedades que tienen un carácter efímero, limitado en el tiempo, consumos inmediatos y obsesión por la apariencia. En este contexto, la promesa de satisfacción inmediata a través del consumo y del individualismo no logra llenar ese vacío interior que se va generando en los individuos.
Lipovetsky describe como, con el advenimiento de la posmodernidad, las promesas de progreso y emancipación se han visto reemplazadas por una búsqueda permanente del placer inmediato, donde lo superficial y lo efímero se convierten en valores predominantes. Es un vacío que va mucho más allá del ámbito social y cultural, y que se extiende también al ámbito de lo subjetivo. El individuo se enfrenta a una sensación de pérdida de sentido que obtiene su mejor reflejo en la percepción de su vida y su relación con los demás. De ahí el título del libro: La era del vacío, que no solamente delata la ausencia de contenido, sino también la falta de profundidad, la superficialidad, que caracteriza a la vida moderna.
Pero el libro no se limita a una mera descripción o diagnóstico de esta situación que acabamos de esbozar, sino que su análisis pretende enfocarse en sus causas. Las transformaciones de la estructura social, la democratización del consumo, el ascenso del neoliberalismo, la tecnificación de las relaciones humanas y, en última instancia, un fenómeno de plena actualidad hoy, en 2025, como es la globalización. Estos son algunos de los factores fundamentales que explican todos estos procesos disolutivos, que Lipovetsky explica desde la perspectiva del sociólogo y el filósofo, manteniendo cierta distancia y ofreciendo respuestas, o soluciones, que huyen de toda simplicidad.
La obra muestra una crítica y escepticismo frente al pensamiento típicamente liberal que nos habla de las ilusiones del progreso y la emancipación total, como parte de las características de la modernidad. Frente a este espejismo, nuestro autor nos invita a reflexionar sobre la necesidad de encontrar nuevos sentidos y valores en un mundo donde éstos parecen desmoronarse por completo. Es una invitación a pensar críticamente sobre nuestra época y reconocer los desafíos que se plantean ante la fragmentación de los grandes relatos de la modernidad y la prevalencia de formas superfluas de existencia.
Uno de los elementos centrales de la obra, como ya hemos señalado al inicio, es la caracterización del hombre contemporáneo como un individuo narcisista, que viene a representar una especie de alternativa frente a la caída de las ideologías, un nuevo tipo humano surgido de la disolución de los grandes relatos colectivos. Y el término no tiene para Lipovetsky ninguna carga peyorativa ni negativa, sino que es un síntoma de esta época, el cual permite comprender cómo ha mutado la subjetividad en el seno de las sociedades del Occidente liberal, en las denominadas «democracias avanzadas».
El narcisista posmoderno no se caracteriza por un ego hipertrofiado en el terreno de lo psicológico, sino por la reorientación de la vida en todos sus aspectos al dominio del yo, que conforma un universo propio, con su bienestar, su apariencia, su desarrollo personal o sus emociones. Es lo que Gilles Lipovetsky concibe como una figura «postheroica», totalmente desvinculada del pathos del sacrificio, del deber, de la militancia política o religiosa. Ha perdido toda conexión con fenómenos de ámbito colectivo, con la lucha de clases propuesta desde filas izquierdistas, por la trascendencia religiosa, ignorando tanto el pasado como el futuro, y radicando su existencia en el presente, en el goce inmediato y la autorrealización subjetiva. Pero conviene insistir en que no se trata de un fenómeno individual o psicológico, sino que obedece a un patrón cultural compartido, moldeado por la lógica del consumo, por la publicidad, por la psicología positiva, por la cultura del entretenimiento y los dispositivos de la autoayuda. Lipovetsky emplea el concepto de «privatización de la existencia» para definir este tipo humano. En el escenario de la vida pública los compromisos ideológicos se diluyen y el ciudadano se transforma en un consumidor, en un mero espectador, en un usuario. La política se reduce a un fenómeno estético, se trivializa y se concibe como un espectáculo, como ese eterno simulacro del que habla Jean Baudrillard o el «postureo» que empleamos desde cierto lenguaje coloquial.
Lejos de advertirse una crítica a este fenómeno, Lipovetsky reconoce en este narcisismo contemporáneo una «forma de emancipación», que a partir de la liberación de los grandes relatos permite formas de vida más «flexibles, más «abiertas» y «tolerantes». Todo ello en un proceso de empobrecimiento del horizonte simbólico, especialmente en lo colectivo, en detrimento del incremento de la autonomía individual. Nosotros añadiríamos, que de una autonomía individual cada vez más atomizada, inorgánica y alienada. De hecho, este individuo hedonista no está dispuesto a sacrificarse por los demás, ni a morir por una causa, y cualquier cosa, por sagrada que sea, es susceptible de ser negociada siempre que revierta en su bienestar.
Las consecuencias derivadas de este proceso, y del nuevo tipo humano posmoderno, son obvias y evidentes, y ahí tenemos la disolución de los lazos sociales fuertes. Vemos cómo las estructuras tradicionales, que han garantizado la cohesión de las comunidades humanas, y que han definido un sentido de pertenencia, un ligamen hacia la Familia, la Religión o la Patria se ven seriamente deteriorados y condenados a desaparecer por completo. Estos elementos han dejado de regular la vida cotidiana, y se imponen vínculos débiles, fluidos y limitados en el tiempo; todo adquiere un sentido limitado en el tiempo, lo efímero domina las relaciones sociales, las afinidades electivas, adquiriendo cierto grado de virtualidad, de ilusorio.
El hombre posmoderno vive rodeado de tecnología, conectado con sus semejantes a través de ordenadores, de las redes sociales, pero solitario, autónomo y desorientado. Con lo cual la «era del vacío» que nos describe Lipovetsky no es realmente un vacío físico o material, sino un vacío simbólico, donde todas las coordenadas que nos conecten a un principio trascendente se encuentran totalmente ausentes. De modo que, el narcisismo clásico de la modernidad más temprana, la que ostentaba el burgués ilustrado, racional y kantiano que creía en la Razón, el Deber o el Progreso, se ha transformado en la posmodernidad, y lo ha hecho a través del narcisista que cree en su «derecho a ser feliz», a «cuidarse» o «experimentar» en una superficialidad que delata la desvinculación de todo centro de gravedad ontológico.
De modo que el hedonismo se nos presenta como el principio rector de la vida social en la era posmoderna, lo cual supone que es una norma compartida, y que conlleva una ética implícita que estructura los comportamientos y aspiraciones, y hasta los valores morales del hombre contemporáneo. Este hecho ha determinado la traslación del «deber» al «placer» en la historia reciente del sujeto occidental, en la que se puede ver cierta idea de «democratización» de esta concepción del narcisismo, de la idea de la «felicidad» y del «culto al yo» en términos puramente materiales, que son transmitidos a través de la publicidad o los manuales de autoayuda.
Este hedonismo está vinculado a una forma particular de existencia, que viene determinada por la lógica del consumo. Y es que para Lipovetsky, como reconoce en otra obra posterior, El imperio de lo efímero, la sociedad ya no se organiza en torno a la producción sino del consumo, entendido éste como el consumo de bienes, experiencias, imágenes, información o sensaciones. De ahí la importancia que poseen para este tipo humano el supermercado, el centro comercial, la pantalla de un ordenador o las redes sociales, que se convierten en el epicentro de la vida posmoderna.

Para Lipovetsky, el acto de consumir no se limita únicamente a las necesidades materiales, sino que se transforma en un «ritual identitario», en una fuente de sentido efímero pero intenso. El hombre posmoderno no compra solo por necesidad, sino para experimentar, como parte de la vida, para definirse. Es un consumo no utilitario, sino expresivo, «para sentirse bien consigo mismo». De modo que este imperativo de bienestar genera una nueva sensibilidad estética: la estética invade la vida cotidiana. La ropa, el diseño interior de una casa, el cuerpo, la alimentación, la música etc, todo se convierte en una cuestión de estilo, en una elección subjetiva. Esto supone que el individuo ya no se define por su pertenencia a un grupo dentro de la jerarquía social ni por su función dentro de la comunidad, sino por su «estética de la existencia». Y es esta estetización de la vida donde, según nuestro autor, reside una forma de construcción de sentido en un mundo desencantado.
No obstante, y siempre según Lipovetsky, este hedonismo posmoderno no se encuentra amparado por el puro libertinaje, sino que el placer también está regulado, normativizado e incluso tecnificado. Lipovetsky insiste en que no se trata de un exceso de placer dionisiaco, sino un placer racionalizado, controlado y saludable. El nuevo hedonista atiende a una responsabilidad, y vemos como hace yoga, se alimenta bien y se cuida en aspectos psicológicos y emocionales. El autor nos habla de un hedonista disciplinado, que gestiona su placer de manera ordenada y eficiente. No obstante, Lipovestsky reconoce que en esta búsqueda del goce y el placer individual, en la búsqueda de una pretendida «libertad» y «autonomía personal», el hedonista posmoderno se somete cada vez más a la tecnología, y es más susceptible de ser controlado por protocolos y normas en nombre de un pretendido bienestar. Todo ello en nombre de lo que en el libro se define como una «reformulación estética y emocional».
Con lo cual, podemos trazar ya en base al libro una cierta definición de la posmodernidad, que más allá de un simple momento histórico, nos ofrece un nuevo marco conceptual, determinado por una transformación profunda a nivel simbólico, ético y estético que han estructurado la cultura llamada occidental desde la Ilustración. Lejos de coincidir con el «fin de la historia» preconizado por Francis Fukuyama, Lipovetsky nos habla de una metamorfosis gradual, caracterizado por la disolución de las grandes narrativas, el debilitamiento del pathos trágico y el auge de la lógica de la inmediatez. Se trata de un enfoque más antropológico y existencial, donde el acento no se pone en una nueva forma de pensar, sino de vivir, de sentir, de relacionarse con el tiempo, con los demás y con uno mismo. Más que una crisis del conocimiento, del saber, se plantea como un reordenamiento del imaginario colectivo, donde el presente hegemoniza todo el interés y se concentra lo trascendente de la escala temporal.
Los grandes ideales desaparecen, aquellos que ofrecían una cierta densidad simbólica y una orientación trascendente. Con la posmodernidad se suprimen las «promesas fuertes» y se promueve una cultura de la «ligereza», de lo provisional, de lo fragmentario. Es un nuevo estilo de vida, menos trágico y combativo, menos solemne, donde lo lúdico y subjetivo acapara amplias cotas de la existencia. Es una mutación cultural donde lo maleable se impone bajo formas de reversibilidad y flexibilidad, todo se hace dúctil, sin compromiso, sin cohesión ni conexión alguna con la trascendencia o sistemas de pensamiento que condicionen la existencia en términos de disciplina y rigidez.
Otro rasgo esencial de la condición del hombre posmoderno es la «evaporación de lo trágico». De algún modo, en la era moderna, el héroe trágico encarnaba la tensión entre el deber y el deseo, entre el orden cósmico y la libertad individual. Sin embargo, en la posmodernidad, esta figura se desvanece, de modo que el sujeto particular ya no se encuentra escindido entre el yo y el deber colectivo, y ahora aparece condicionado por su propio presente, por sus decisiones cotidianas, la gestión de su tiempo, de su cuerpo y cuestiones que se desarrollan en un plano estrictamente personal. La cultura posmoderna evita el conflicto trágico, desplaza la culpa y trivializa el mal. Ya no encontramos el pathos heroico, sino el tono cool, la distancia frente a los hechos y la ironía. Y así tenemos la política convertida en un mero espectáculo, en el arte autorreferencial, en el relativismo moral, y, en definitiva, con un pensamiento débil.
Pero para el sociólogo francés esta ausencia de lo trágico no debe interpretarse como una pérdida, y para él el vacío no es nihilismo, sino una nueva forma de relacionarse con el ser, de manera menos intensa, más liviana, menos sagrada pero más «habitable». El hombre no cae en el desencanto, ni tampoco renuncia a encontrar sentido, pero lo busca de forma dispersa y provisional, sin grandes pretensiones. De este modo la vida se reduce a una relación entre vacío y deseo, entre la autonomía y la saturación de estímulos, que al fin y al cabo supone otro vacío, porque tras la saturación de estímulos solamente hay un sucedáneo de felicidad, dentro de esa tendencia a lo efímero, tras la cual, solo queda el vacío absoluto.
Y es que el diagnóstico que Lipovestsky nos hace de la cultura posmoderna sitúa como elemento central el papel de los medios de comunicación y la cultura del espectáculo. La televisión, el cine y la publicidad, a los que hoy podríamos añadir internet y las redes sociales, no son meros vehículos de información o entretenimiento, sino que son estructuras simbólicas que reconfiguran la sensibilidad, el tiempo y la percepción de la realidad. De hecho son los medios de comunicación de masas los instrumentos y catalizadores en la difusión de la cultura narcisista y el hedonismo personalizado, en la que el principio racional y discursivo cede su lugar a formas más emocionales, fragmentadas y efímeras en la relación con el entorno y el mundo en definitiva. De hecho, el lenguaje de lo visual, totalmente sobredimensionado, ha generado todo un lenguaje que se ha hecho dominante en nuestra época, en el que se privilegia la apariencia y la vivencia subjetiva por encima de toda estructura estable y jerárquica. Y de ahí deriva la espectacularización generalizada a través de la imagen, del impacto que produce, erosionando las fronteras entre lo público y lo privado, entre lo verdadero y simulado, entre el acontecimiento y la escenificación.
En este contexto, el espectador sustituye al ciudadano comprometido, y la política se convierte en un consumo simbólico, en el que el sentido de comunidad es reemplazado por consensos mediáticos efímeros. Para Lipovetsky no es, una vez más, una tragedia, sino que produce un efecto ambivalente: y si bien debilita el compromiso, también produce una sensibilidad más abierta, plural y tolerancia hacia la diferencia. Todo esto, bajo un aparente lenguaje académico y bienpensante, que no hace sino alimentar el pensamiento débil y la destrucción de cualquier idea o principio comunitario sustentado sobre pensamientos fuertes, sobre un principio de jerarquía y cohesión a nivel colectivo.
El hombre posmoderno ignora toda tensión espiritual, y en consecuencia vive la temporalidad de forma acelerada y discontinua, sometido a un flujo incesante de información, de novedades, y concibe su entorno y los estímulos que recibe de éste, desde la perspectiva de la obsolescencia programada. Por eso no se plantea jamás el porvenir e ignora por completo el pasado, para vivir bajo un «presentismo» hedonista, de tal modo que en su percepción del tiempo este no es sino un conjunto de instantes vividos, registrados, compartidos y, en última instancia, olvidados. Así se pierde el sentido de continuidad y duración, impidiendo que tanto a nivel colectivo como individual se pueda construir una identidad coherente o cimentar aquella existente.
Esto lo vemos a través de la cultura digital, aunque en el año que Lipovetsky escribe su libro, en 1983, todavía se encontraba en un estado embrionario o incipiente, pero ya se impone la idea de la hiperconexión, la instantaneidad, la lógica del feed y de la viralidad, que ahondan sobre una experiencia centrífuga del tiempo, donde ya no importa lo que es duradero, sino lo que aparece, lo que afecta y circula en un cambio continuo. De tal modo que el individuo se adapta a la velocidad más que a la profundidad.
Obviamente, la consecuencia es el debilitamiento y la destrucción de todas las formas narrativas tradicionales, tanto a nivel religioso e histórico como ideológico e incluso familiar. Todas estas estructuras, que garantizaron durante generaciones una estabilidad y cohesión en diferentes planos, pierden su poder para dejar su lugar a la cultura de las vivencias dispersas, fragmentadas e inconsistentes. Todo queda reducido al capricho de la experiencia subjetiva del individuo, a sus elecciones de consumo o sus afectos momentáneos. Y tenemos un amplio reflejo de estas ideas en todos los ámbitos, en el arte, en el cine o en la política. La «democratización cultural» y el «pluralismo ético» al que alude el autor, no es sino la destrucción de certezas y principios de carácter vertical, verdades íntegras y sagradas que entran en declive hasta desaparecer.
Ahora bien, una vez destruido el sentido profundo y cohesionador de las grandes instituciones normativas, como la familia, la escuela o el Estado, que sustentaban el cuerpo social mediante su legitimidad simbólica, ¿qué impacto pueden tener sobre los fundamentos éticos y educativos de la sociedad? ¿Qué ocurre con la transmisión de valores, la responsabilidad moral o el pensamiento crítico en una época tan volátil y carente de toda solidez? No existe ningún principio de autoridad en el que cimentar ninguno de estos principios, todo ha sido sacrificado en nombre de la autonomía individual, la horizontalidad y las identidades subjetivas. Es evidente que se ha generado un vacío y la falta de un anclaje o asidero en los procesos educativos. Los profesores ya no encarnan una figura de autoridad, y se encuentran supeditados a las exigencias de los alumnos, a su satisfacción emocional, a su sensibilidad, a garantizar que no se aburran, relegados a una posición de negociación constante. De ahí que la educación y el papel del docente se vea obligado a reformularse y adaptarse a nuevas formas de pedagogía, que en opinión del sociólogo francés, debe adaptarse a la transmisión de conocimientos para «formar subjetividades» dentro de una «pedagogía de la autonomía crítica» que no imponga valores.
En esta era del vacío, caracterizada por el debilitamiento, cuando no aniquilación, de los valores trascendentes, ya no hay una moral universal que pueda orientar las acciones. Lo que prima es una ética débil, individual, basada en la sensibilidad, en la empatía y eso que los progres y globalistas llaman «respeto a la diferencia», que entra en contraste con el desprecio y degradación de lo propio, de lo que le es familiar, de la Tradición en definitiva. Y que lejos de las observaciones de Lipovetsky, sí supone la caída en un relativismo autodestructivo. De hecho, el autor francés ve todas estas transformaciones propiamente posmodernas, de un pensamiento débil, fragmentado, antijerárquico y servil ante cualquier contaminación cultural o asunción de los valores destructivos y globalistas del melting pot como el efecto de una evolución positiva, donde lo emocional y afectivo, lo irracional, invita a la claudicación en nombre de una falsa justicia social, un falso ecologismo o la desfiguración de componentes étnicos, tradicionales e identitarios a nivel colectivo, para defender al modelo multicultural y globalizado, estandarizado y yermo de particularidades. Precisamente lo que hoy tenemos, con países totalmente destruidos en su esencia histórica, étnica y de legados tradicionales en la Europa occidental. Todo en nombre de un pensamiento superficial, fugaz y débil, entregado a los protocolos, normativas e imposiciones de una plutocracia global que somete e impone a una masa idiotizada Agendas en nombre de pretendidos principios de justicia que no son sino la antesala de formas aberrantes y deshumanizadoras de control tecnocrático.
Para terminar, aunque ya hayamos adelantado alguna de nuestras conclusiones respecto al libro, creemos que Gilles Lipovetsky ofrece una visión funcional a la posmodernidad, a la justificación de una serie de transformaciones sociales, culturales, políticas y humanas, que lejos de tener un efecto positivo, de evolución y progreso, envilecen y destruyen a la propia condición humana. La conversión del hombre en un ser infantilizado, egoísta y pusilánime, incapaz de adquirir compromisos colectivos, del sacrificio por grandes ideales que han sustentado modelos de civilización perpetuados en los siglos, no es sino el síntoma de un gran fracaso, de la claudicación del hombre, síntoma de la cultura de la cancelación y la promoción de una antropología negativa y el fomento del nihilismo, por más que se trate de camuflar con eufemismos absurdos y un lenguaje academicista totalmente hueco, retórica vacía, que no deja de ocultar una crítica necesaria frente a cambios estructurales que no son, ni mucho menos, el fruto de una evolución natural, sino totalmente inducidos, y en los que la tecnología sirve de medio de alienación generalizada del sujeto posmoderno. La «era del vacío» de la que nos habla Lipovetsky es una época de decadencia, degeneración, caos y deshumanización, y sin duda alguna es una oportunidad para volver a conectar con el pasado, para religarse con la Tradición e invertir el signo de los tiempos.
Desde un enfoque específicamente tradicionalista, el diagnóstico que Lipovestky nos hace de la sociedad posmoderna, si bien puede ser válido y aceptable desde una perspectiva crítica, resulta insuficiente porque no podemos insertarlo en una cosmovisión propiamente tradicionalista, y suran una sociedad tradicional completamente ajena a los ítems ideológicos que representa esta última. De ahí que la Modernidad, para René Guénon, por ejemplo, represente una desviación extrema de los principios metafísicos y universales que estructuran las civilizaciones tradicionales. Para Lipovetsky esté fenómeno es relativamente reciente, y no el resultado de un proceso histórico amplio y contrastado, que comienza a gestarse en los siglos. Lipovetsky diferencia la modernidad y la posmodernidad, como si fueran dos procesos independientes, en los que solamente nos habla de síntomas sin realizar un análisis de conjunto que llegue a la raíz metafísica del problema. Tanto para René Guénon como para Julius Evola, el individualismo se trata de un proceso de involución espiritual, un descenso hacia lo material y lo informe, algo que no entraña ningún aspecto positivo, y menos en los términos de una «mayor libertad», y donde Lipovetsky ve una posibilidad y una serie de cambios adaptativos, el tradicionalismo ve una forma de claudicación ante lo moderno.
La posición fría, distante y observadora de Lipovetsky difiere radicalmente del tradicionalismo, y no solo por esa ausencia de profundidad en el terreno de lo metafísico, sino porque no ofrece ninguna alternativa al oscurecimiento de lo sagrado, y se limita a una mera descripción de la decadencia, todo desde la perspectiva del científico.
Además, la superficialidad de Lipovetsky se queda únicamente en la catalogación cultural de fenómenos como el hedonismo y el individualismo, sin abordar la radical antítesis que éstos representan frente a lo espiritual. La actitud resignada del sociólogo francés actúa en el marco mental e ideológico de la posmodernidad, frente a la cual no hay que mostrar ningún tipo de alternativa, ni restaurar jerarquías naturales, ni apostar por valores heroicos y aristocráticos, ni mucho menos por la formación de una élite espiritual. Es obvio que el marco conceptual e ideológico en el que actúa este autor es radicalmente ajeno a cualquier concepción morfológica de la historia y concepción tradicional aneja a la misma.
Por otro lado, no se dejan de evidenciar lagunas en su discurso, en la medida que ve en el individualismo el motor de la posmodernidad, y lo asocia a la liberación respecto a las «ataduras» colectivas que representan la Patria, la religión o la comunidad, pero frente a éstas reconoce que solo queda un vacío existencial. Es un individualismo, que nada tiene que ver con aquel individualismo del kshatriya integrado en una jerarquía espiritual, que se erige como guía y estandarte espiritual frente a las naturalezas inferiores. El individualismo posmoderno no tienden a la diferenciación, sino que tiene un efecto de degeneración y envilecimiento a través de la autoexpresión narcisista y el hedonismo, atributos característicos del burgués y de la degenerada antropología liberal.
En definitiva, Lipovetsky es incapaz de proponer una salida positiva al conflicto que plantea la posmodernidad. Para él debe ser aceptado como un estadio inevitable de la historia, mientras que el tradicionalismo exige una ruptura total y absoluta con el mundo moderno, en la que la primacía de los principios metafísicos se convierte en una piedra angular, y son innegociables. El autor francés permanece atrapado en las paradojas y antinomias de un horizonte secular que critica, cayendo en una contradicción insoluble y sin posibilidad de continuidad. La «era del vacío», que abarca un periodo más amplio que el de la propia posmodernidad, representa un punto de ruptura con la Tradición primordial, y plantea una única salida, la cual pasa por la restauración jerárquica y espiritual. No podemos contemplar todos estos procesos disolutivos anejos a nuestro tiempo con la «neutralidad» de Gilles Lipovetsky, sin atender a la existencia de un horizonte metafísico y de Verdades eternas, rescatando el principio de lo Sagrado y la acción heroica en última instancia.

2025-04-28 08:50:14Imagine a classroom where learning is as engaging as your favorite playlist, complex concepts are sung rather than slogged through, and students eagerly anticipate their lessons. This isn’t some utopian dream—it's the reality when music is integrated into education. Music isn’t just a tool for entertainment; it’s a powerful ally in enhancing learning. From improving literacy and language skills to helping those with autism, Daniel Siegel Alonso explores how music makes education a harmonious experience.
Literacy is the bedrock of education, and music can play a pivotal role in forging that foundation. Studies have shown that musical training can significantly enhance reading skills. Music's rhythmic and melodic patterns help spark phonological awareness, which is critical for reading.
Siegel Alonso takes the example of “singing the alphabet.” This simple, catchy tune helps children remember letter sequences more effectively than rote memorization. But it doesn’t stop there. Programs like “Reading Rocks!” incorporate songs and rhymes to teach reading. By engaging multiple senses, these programs make learning to read more interactive and enjoyable.
Music also aids in comprehension and retention. Lyrics often tell stories; children can better grasp narrative structure and vocabulary through songs. The melody and rhythm act as mnemonic devices, making it easier to recall information. So, next time you catch yourself singing a line from a song you heard years ago, remember: your brain’s just showing off impressive recall skills.
Music is a universal language that can bridge cultural and linguistic divides. It offers a fun and effective method for grasping vocabulary, pronunciation, and syntax for those learning a new language.
Siegel Alonso considers the success of the “Language through Music” approach, where songs in the target language are used to teach linguistic elements. Listening to and singing songs helps learners familiarize themselves with the natural rhythm and intonation of the language. It’s like getting a musical earworm that teaches you how to conjugate verbs.
Children’s tunes are particularly effective. They are repetitive, use simple language, and are often accompanied by actions, making them ideal for language learners. Adults can also benefit; think of the many people who have learned basic phrases in a foreign language by singing along to popular songs.
Moreover, music can make the uphill battle of language learning enjoyable. Picture learning Spanish through the vibrant beats of salsa or French through the soulful chansons of Edith Piaf. Music's emotional connection can deepen engagement and motivation, transforming language lessons from a chore into a delightful activity.
For individuals with autism, music can be a bridge to communication and social interaction. Autism often affects language development and social skills, but music has a unique way of reaching across these barriers. Music therapy has shown remarkable results in helping those with autism.
Through musical activities, individuals can express themselves nonverbally, which is especially beneficial for those who struggle with traditional forms of communication. Music can also help develop speech, improve social interactions, and reduce anxiety.
There are many anecdotes of nonverbal autistic children who struggle to communicate. But when they were introduced to music therapy, they began to hum and eventually sing along with their therapist. This breakthrough provided a new way for them to express their feelings and needs, fostering better communication with their family and peers.
Music also helps develop routines and transitions, which can be challenging for individuals with autism. Songs that signal the start of an activity or the end of the day create a predictable structure that can reduce anxiety and improve behavior. Additionally, group music activities encourage social interaction and cooperation, providing a fun and safe environment for practicing these skills.
Music’s impact on learning is profound and multifaceted. It’s not just a tool for young children or those facing specific challenges; it’s a lifelong ally in education. Music's benefits are vast, whether it’s helping students understand mathematical concepts through rhythm, enhancing memory and cognitive skills, or providing a creative outlet.
Integrating music into educational settings creates a more dynamic and engaging learning environment. It adapts to different learning styles, making lessons accessible and palatable for all students. Music fosters a safe, positive, and stimulating atmosphere where learning is effective and joyful.
As we continue to analyze and unlock the power of music in education, Daniel Siegel Alonso notes that it’s clear that the thread between learning and music can lead to academic and personal success. So, let’s keep the music playing in our schools and beyond, ensuring that education hits all the right notes.

2025-03-26 12:06:30When designing a highly available Kubernetes (or k3s) cluster, one of the key architectural questions is: "How many ETCD nodes should I run?"
A recent discussion in our team sparked this very debate. Someone suggested increasing our ETCD cluster size from 3 to more nodes, citing concerns about node failures and the need for higher fault tolerance. It’s a fair concern—nobody wants a critical service to go down—but here's why 3-node ETCD clusters are usually the sweet spot for most setups.
The Role of ETCD and Quorum
ETCD is a distributed key-value store used by Kubernetes to store all its state. Like most consensus-based systems (e.g., Raft), ETCD relies on quorum to operate. This means that more than half of the ETCD nodes must be online and in agreement for the cluster to function correctly.
What Quorum Means in Practice
- In a 3-node ETCD cluster, quorum is 2.
- In a 5-node cluster, quorum is 3.
⚠️ So yes, 5 nodes can tolerate 2 failures vs. just 1 in a 3-node setup—but you also need more nodes online to keep the system functional. More nodes doesn't linearly increase safety.
Why 3 Nodes is the Ideal Baseline
Running 3 ETCD nodes hits a great balance:
- Fault tolerance: 1 node can fail without issue.
- Performance: Fewer nodes = faster consensus and lower latency.
- Simplicity: Easier to manage, upgrade, and monitor.
Even the ETCD documentation recommends 3–5 nodes total, with 5 being the upper limit before write performance and operational complexity start to degrade.
Systems like Google's Chubby—which inspired systems like ETCD and ZooKeeper—also recommend no more than 5 nodes.
The Myth of Catastrophic Failure
"If two of our three ETCD nodes go down, the cluster will become unusable and need deep repair!"
This is a common fear, but the reality is less dramatic:
- ETCD becomes read-only: You can't schedule or update workloads, but existing workloads continue to run.
- No deep repair needed: As long as there's no data corruption, restoring quorum just requires bringing at least one other ETCD node back online.
- Still recoverable if two nodes are permanently lost: You can re-initialize the remaining node as a new single-node ETCD cluster using
--cluster-init
, and rebuild from there.
What About Backups?
In k3s, ETCD snapshots are automatically saved by default. For example:
- Default path:
/var/lib/rancher/k3s/server/db/snapshots/
You can restore these snapshots in case of failure, making ETCD even more resilient.
When to Consider 5 Nodes
Adding more ETCD nodes only makes sense at scale, such as:
- Running 12+ total cluster nodes
- Needing stronger fault domains for regulatory/compliance reasons
Note: ETCD typically requires low-latency communication between nodes. Distributing ETCD members across availability zones or regions is generally discouraged unless you're using specialized networking and understand the performance implications.
Even then, be cautious—you're trading some simplicity and performance for that extra failure margin.
TL;DR
- 3-node ETCD clusters are the best choice for most Kubernetes/k3s environments.
- 5-node clusters offer more redundancy but come with extra complexity and performance costs.
- Loss of quorum is not a disaster—it’s recoverable.
- Backups and restore paths make even worst-case recovery feasible.
And finally: if you're seeing multiple ETCD nodes go down frequently, the real problem might not be the number of nodes—but your hosting provider.

2025-04-28 08:33:05Author: Wanbiao Ye, CKB Core Developer Nervos Network
Secp256k1 and ECDSA aren't just common—they're the backbone of digital signatures in today’s leading blockchains. From Bitcoin (see Bitcoin Wiki) to Ethereum (see Yellow Paper, Appendix E. Precompiled Contract) to CKB (See this RFC), these algorithms are the default choice. They’re what let you prove ownership with your private key — your on-chain assets belong to you, and only you.
Elliptic curves are favored in cryptography because they provide high security with shorter keys. But are they truly secure and perfect? However, the U.S. National Institute of Standards and Technology (NIST) recently indicated concerns about security risks associated with secp256k1 and does not currently endorse its use. Instead, it suggests an alternative curve: secp256r1 (see Recommendations for Discrete Logarithm-based Cryptography, p1). Meanwhile, Bitcoin is evolving—introducing Schnorr signatures in 2021 to replace ECDSA.
The core issue is ECDSA itself—it is highly vulnerable and has caused serious incidents. In this post, we’ll revisit the key attacks, reproduce them, and explain how CKB's segregated witness design and support for upgradable cryptographic algorithms help mitigate these risks. I’ll walk you through a historical overview and attempt to recreate some of the most infamous attacks: nonce reuse attack, invalid curve attack, transaction malleability attacks, and side-channel attacks. Finally, I’ll highlight how CKB addresses these issues through Segregated Witness and support for upgradable cryptographic algorithms—by excluding ECDSA signatures from the transaction hash and enabling algorithm upgrades, so that developers can adopt solutions that best suit their needs without compromising security.
This article uses the following notation:
|
m
| Message | 256-bit integer | | --- | --- | --- | |r
| Part of the signature | 256-bit integer | |s
| Part of the signature | 256-bit integer | |k
| Nonce used during signing | 256-bit integer | |g
| Generator point on the elliptic curve representing (x, y) coordinates | two 256-bit integers |Nonce Reuse Attack
Due to Bitcoin, secp256k1 and ECDSA became widely known. But they weren’t obscure before. For example, Sony used to mark its PlayStation firmware as valid and unmodified using a private key stored at the company's headquarters. PlayStation 3 only requires a public key to verify that the signature is from Sony. But unfortunately, Sony was hacked due to their poor code implementation, meaning that any future system updates they release could be easily decrypted.
At fail0verflow, hackers demonstrated part of Sony’s ECDSA code and discovered that Sony kept the value of the random number always at 4, which caused the random private key
k
in the ECDSA signature process to always have the same value. ECDSA requiresk
to be randomly generated every time. Reusing it leaks the private key.python def get_random_number(): # Chosen by fair dice roll. Guaranteed to be random. return 4
Given:
-
Message
m₁
and signature(r₁, s₁)
-
Message
m₂
and signature(r₂, s₂)
-
Both
m₁
andm₂
are signed with the same unknownk
Then:
```plaintext s₁ = (m₁ + prikey * r₁) / k s₂ = (m₂ + prikey * r₁) / k s₁ / s₂ = (m₁ + prikey * r₁) / (m₂ + prikey * r₁) prikey = (s₁ * m₂ - s₂ * m₁) / (s₂ - s₁) / r₁
```
A real-world example to help you better understand how a private key can be recovered from two signatures that use the same random number
k
:```python import pabtc
m1 = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e) r1 = pabtc.secp256k1.Fr(0x741a1cc1db8aa02cff2e695905ed866e4e1f1e19b10e2b448bf01d4ef3cbd8ed) s1 = pabtc.secp256k1.Fr(0x2222017d7d4b9886a19fe8da9234032e5e8dc5b5b1f27517b03ac8e1dd573c78)
m2 = pabtc.secp256k1.Fr(0x059aa1e67abe518ea1e09587f828264119e3cdae0b8fcaedb542d8c287c3d420) r2 = pabtc.secp256k1.Fr(0x741a1cc1db8aa02cff2e695905ed866e4e1f1e19b10e2b448bf01d4ef3cbd8ed) s2 = pabtc.secp256k1.Fr(0x5c907cdd9ac36fdaf4af60e2ccfb1469c7281c30eb219eca3eddf1f0ad804655)
prikey = (s1 * m2 - s2 * m1) / (s2 - s1) / r1 assert prikey.x == 0x5f6717883bef25f45a129c11fcac1567d74bda5a9ad4cbffc8203c0da2a1473c ```
Invalid Curve Attack
Invalid Curve Attack involves using points not on the intended curve. Attackers can bypass signature verification or key validation by crafting an invalid public key.
During the signing process, an attacker could somehow construct an invalid public key. This invalid public key has some mathematical relationship with the attacker's private key (for example, the attacker signs by forging an invalid public key), which allows the attacker to generate a seemingly valid signature. Normally, the signature verification algorithm would check whether the public key is within the secp256k1 curve range. If the public key is invalid, the system should reject the signature. However, assuming the system does not perform sufficient curve point validity checks, the attacker could submit a request containing an invalid public key and a forged signature. In some cases, the system might incorrectly accept this invalid signature, considering it as legitimate. The attacker's signature could pass the system's checks, causing malicious transactions or operations to be wrongly considered valid, thus executing certain illegal actions, such as transferring funds or modifying data.
A real-world example is the elliptic curve verification vulnerability in OpenSSL. In 2015, an OpenSSL version prior to v1.0.2 had an elliptic curve verification vulnerability. An attacker could construct an invalid elliptic curve point and use it as a public key, exploiting certain vulnerabilities in OpenSSL to bypass verification, thus attacking systems using the library. This vulnerability, known as CVE-2015-1786, allowed attackers to bypass signature verification by forging an invalid public key. The same issue also occurred in the ECDSA library used by Bitcoin Core, where earlier versions of the library did not perform sufficient checks on elliptic curve points.
Before this vulnerability was fixed, attackers could bypass the system's curve validity checks without proper verification, leading to potential denial of service or other security issues.
Transaction Malleability Attack
In ancient times, if you hammered a gold coin, it changed shape but kept its value. This is called malleability.
Mt. Gox was once the largest Bitcoin exchange in the world. The company, headquartered in Tokyo, is estimated to have accounted for 70% of Bitcoin trading volume in 2013. In 2014, the exchange was hacked, resulting in a loss of approximately 850,000 Bitcoins. The hackers employed a technique known as a transaction malleability attack.
The specific process of the attack is as follows:
-
The attacker initiates a withdrawal Tx A on Mt. Gox
-
Before Tx A is confirmed, it manipulates the transaction's signature, causing the transaction hash, which uniquely identifies the transaction, to change and generating a forged Tx B.
-
Tx B is confirmed on the blockchain, and the exchange receives a failure message for Tx A.
The exchange mistakenly believes that the withdrawal has failed and constructs a new withdrawal transaction for the attacker.
The core of this attack is that the attacker can modify parts of the transaction's signature (such as the input signature) or other non-critical fields, thereby changing the transaction's hash, but without altering the actual content of the transaction.
Coincidentally, secp256k1 + ECDSA indeed provides a very convenient method that allows attackers to modify the signature result while still passing the signature verification. If we analyze the ECDSA signature verification algorithm, we find that the verification result is independent of the sign of the s value in the signature (r, s).
To verify this, we write the following test code:
```python import pabtc
prikey = pabtc.secp256k1.Fr(1) pubkey = pabtc.secp256k1.G * prikey msg = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e)
r, s, _ = pabtc.ECDSA.sign(prikey, msg) assert pabtc.ECDSA.verify(pubkey, msg, r, +s) assert pabtc.ECDSA.verify(pubkey, msg, r, -s) ```
In the above code, we signed a message with the private key and then took the negative sign of the s value in the signature. We found that the modified signature still passed the ECDSA verification.
Bitcoin had this attack risk in its earlier versions. Attackers used a malleability attack to break the immutability of transactions, leading to severe security issues. To solve this problem, Bitcoin made improvements in the Segregated Witness (SegWit) upgrade. SegWit separated the signature part of the transaction from the other data, so even if the attacker altered the signature part, the transaction hash would no longer be affected, thus solving the transaction malleability issue.
This problem also has similar impacts on other blockchain systems, so many projects have adopted solutions similar to SegWit to ensure the integrity and traceability of transactions. Another solution is the one taken by Ethereum, where additional requirements were imposed on the s value in the signature. Ethereum requires that s must be smaller than
pabtc.secp256k1.N / 2
. You can find Ethereum's detailed solution to the transaction malleability attack in Appendix F. Signing Transactions in its Yellow Paper (p. 26).As a poem goes:
Mt. Gox, the name on the door,
So many users, could there be more?
Bitcoin stolen, hearts hit the floor.
Hashes changed, transactions no more.
Cold wallets emptied, riches out the door,
Gone with the wind, the wealth we adore.Side-Channel Attack
On a flight, I sat next to a man who kept checking stock prices. We chatted briefly, and he mentioned the market was bad this year, then asked me to guess how much he’d lost.
I said, “Probably around a hundred thousand.”
Surprised, he asked how I knew.
I explained: He wore business attire but carried a Swiss Army backpack—clearly not a top exec, more like business development. His Armani watch suggested mid-level income. His shirt was old but well-pressed—his wife likely takes care of him. The Hello Kitty charm on his bag hinted at a young daughter. His stock picks were all tech-related, so he’s probably in the industry. Based on all this, I estimated his disposable capital was around 200–300k, so losing 100k made sense. Dark circles and thinning hair showed stress; his wife likely didn’t know about the losses. I also saw a newly downloaded crypto trading app on his phone—he was probably planning to gamble on crypto next. Then I tapped open his stock app: 280k invested, 102k lost.
He didn’t say another word during the flight. Just sat there, rubbing his eyes. His meal remained untouched.
The story above comes from the Chinese internet, first appearing in 2015. Due to its widespread reposting, the author is unknown. In this story, "I" launched a side-channel attack on the man. Although he didn’t reveal any information about his personal investments, his financial status influences his attire, so we can reverse-engineer his financial situation through his clothing.
In cryptography, a side-channel attack refers to a method of using physical or behavioral information (such as execution time, power consumption, electromagnetic radiation, etc.) generated during a device's operation to break a cryptographic or signature scheme.
For secp256k1 elliptic curve and ECDSA signature schemes, such an attack could infer the private key by analyzing the execution characteristics of crucial operations.
In ECDSA, the signing process involves generating a random number
k
used to calculate part of the signature. The security of this randomk
is crucial; Once leaked, the private key is compromised:Example:
Given the following information, please compute the secp256k1 private key:
plaintext m = 0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e k = 0x1058387903e128125f2715d7de954f53686172b78c3f919521ae4664f30b00ca r = 0x75ee776c554b1dd5e1680a4cc9a3d0e8cb11400742d8af0222ce383e642f98db s = 0x35fd48c9157256558184e20c9392ff3c9517f9753e3745aede06cab285f4bc0d
Answer:
python prikey = (s * k - m) / r assert prikey == 1
The verification code is as follows:
```python import pabtc
m = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e) k = pabtc.secp256k1.Fr(0x1058387903e128125f2715d7de954f53686172b78c3f919521ae4664f30b00ca) r = pabtc.secp256k1.Fr(0x75ee776c554b1dd5e1680a4cc9a3d0e8cb11400742d8af0222ce383e642f98db) s = pabtc.secp256k1.Fr(0x35fd48c9157256558184e20c9392ff3c9517f9753e3745aede06cab285f4bc0d)
prikey = (s * k - m) / r assert prikey == pabtc.secp256k1.Fr(1) ```
The calculation of the random number
k
involves elliptic curve point multiplication and modular inversion operations (typically implemented using the extended Euclidean algorithm). These operations may have execution times that depend onk
, and side-channel attackers can measure execution time differences to extract information aboutk
. To demonstrate the principle, I will try to simplify the attack process.Example: Suppose there is an unknown random number
k
, and a hacker is somehow able to detect the execution time ofg * k
. Try to see if it's possible to extract some information about the random numberk
.Answer: By examining the point multiplication algorithm on elliptic curves, we find that different operations are executed depending on the bit value of
k
. When a bit is 0, the amount of computation is less than when the bit is 1. We first take two differentk
values—one with most bits being 0, and the other with most bits being 1—and measure the difference in their execution times. Then, when a new unknownk
is used in the computation, we detect its execution time and compare it with the previous two values. This allows us to roughly estimate how many 1 bits are present in the unknownk
.The experimental code is shown below. Note: To simplify the attack steps, in the experimental code we assume that the first bit of all participating
k
values is always 1.```python import pabtc import random import timeit
k_one = pabtc.secp256k1.Fr(0x800000...) k_255 = pabtc.secp256k1.Fr(0x7fffff...) k_unknown = pabtc.secp256k1.Fr(random.randint(0, pabtc.secp256k1.N - 1) | k_one.x)
a = timeit.timeit(lambda: pabtc.secp256k1.G * k_one, number=1024) b = timeit.timeit(lambda: pabtc.secp256k1.G * k_255, number=1024) c = timeit.timeit(lambda: pabtc.secp256k1.G * k_unknown, number=1024)
d = (c - a) / ((b - a) / 254) print(d) ```
The attack process described above is a timing attack, which is a type of side-channel attack. To defend against timing attack, you can introduce constant-time operations in the code to avoid leaking information, such as using fixed-time addition and multiplication operations to prevent timing differences from being exploited.
In real-world applications, preventing side-channel attacks in cryptographic algorithms requires comprehensive security optimizations at the algorithm, hardware, and software levels. However, since the secp256k1 and ECDSA schemes were not designed with such attacks in mind, defending against them is particularly difficult and complex.
CKB's Approach: Segregated Witness + Upgradable Cryptographic Algorithms
In terms of transaction structure, CKB adopts Bitcoin’s Segregated Witness scheme, meaning that the transaction hash does not include the ECDSA signature. This design helps prevent transaction malleability attacks. See the Transaction Hash section of the RFC for details.
The Secp256k1 + ECDSA scheme is CKB’s default signature scheme, but thanks to CKB’s custom cryptographic primitives and native account abstraction capabilities, we can easily implement many other cryptographic algorithms in CKB, as well as upgrade existing ones. Developers on CKB are free to choose any algorithm they trust to protect the assets, including but not limited to:
Final Remarks
In short, although secp256k1 and ECDSA are widely used and quite secure when implemented properly and used correctly, we still must not overlook some of their potential vulnerabilities. Thanks to Bitcoin’s development, secp256k1 and ECDSA have gained great fame, but they have also attracted more attention from cryptographers and malicious hackers. In the future, more types of attacks on secp256k1 may be gradually discovered and exploited. Therefore, staying vigilant, updating in time, and following the latest security best practices is critical for maintaining system security. As the field of cryptography continues to advance, there are already some more secure and efficient alternatives available. But regardless of this, understanding and addressing current risks remains the responsibility and challenge of every developer.

Secp256k1 与 ECDSA 椭圆曲线不仅常见,更是当今区块链数字签名的基础。从比特币(见 Bitcoin Wiki)到以太坊(见 Yellow Paper, Appendix E. Precompiled Contract)再到 CKB (见 RFC 24 相关部分) ,secp256k1 + ECDSA 都是它们的默认选择。它们让你通过私钥证明所有权——你的链上资产属于你,且仅属于你。
椭圆曲线之所以在密码学中有优势,因为它们可以在较小的密钥长度下提供更高的安全性。 但是, 它们真的是安全且完美的算法吗?美国国家标准与技术研究院(NIST)最近认为 secp256k1 存在一些安全风险,已经不建议使用。作为替代,它们建议使用另一条名为 secp256r1 的椭圆曲线(见 Recommendations for Discrete Logarithm-based Cryptography, p1)。另一方面,比特币自身也在改变——在 2021 年引入了一种叫做 Schnorr 的签名算法来尝试替代 ECDSA。
促成这些改变的本质原因是因为 ECDSA 签名算法自身的问题——极其容易受到攻击,并造成过许多灾难性的后果。在本次分享中,我将带领大家回顾历史,并尝试重现这些历史上的著名攻击:随机数重用攻击、心脏点攻击、交易延展攻击、旁路攻击。最后我将指出 CKB 所采用的隔离见证,配合支持加密算法升级的方式——交易哈希不包含 ECDSA 签名,并允许算法升级,在确保安全的同时让用户可以采用更适合自己需求的方案。
本文会使用一些数学符号,约定如下:
|
m
| 消息 | 256 位整数 | | --- | --- | --- | |r
| 签名的一部分 | 256 位整数 | |s
| 签名的一部分 | 256 位整数 | |k
| 随机数字,在签名时需要用到 | 256 位整数 | |g
| 椭圆曲线的生成点,代表坐标 x 和 y | 两个 256 位整数 |随机数重用攻击
因为比特币的原因,secp256k1 椭圆曲线以及 ECDSA 签名算法变得无人不知、无人不晓。但其实在比特币之前,它们也并非无人问津。例如在 Playstation 3 时代,索尼就使用存储在公司总部的私钥将其 Playstation 固件标记为有效且未经修改。Playstation 3 只需要一个公钥来验证签名是否来自索尼。 但不幸的是,索尼因为他们糟糕的代码实现而遭到了黑客的破解,这意味着他们今后发布的任何系统更新都可以毫不费力地解密。
在 fail0overflow 大会上, 黑客展示了索尼 ECDSA 的部分代码, 发现索尼让随机数的值始终保持 4, 这导致了 ECDSA 签名步骤中的随机私钥 k 始终会得到相同的值。ECDSA 签名要求随机数 k 是严格随机的, 如果重复使用 k, 将直接导致私钥泄露.
python get_random_number(): # Chosen by fair dice roll. Guaranteed to be random. return 4
例:有以下信息,求私钥 prikey
-
信息 m₁ 及其签名 (r₁, s₁);
-
信息 m₂ 及其签名 (r₂, s₂);
-
信息 m₁ 和 m₂ 使用相同的随机数 k 进行签名, k 的具体数据则未知。
答:
plaintext s₁ = (m₁ + prikey * r₁) / k s₂ = (m₂ + prikey * r₂) / k = (m₂ + prikey * r₁) / k s₁ / s₂ = (m₁ + prikey * r₁) / (m₂ + prikey * r₁) prikey = (s₁ * m₂ - s₂ * m₁) / (s₂ - s₁) / r₁
这里有一个实际的例子可以帮助大家更直观的理解,如何通过两个使用相同随机数 k 的签名来还原私钥:
```python import pabtc
m1 = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e) r1 = pabtc.secp256k1.Fr(0x741a1cc1db8aa02cff2e695905ed866e4e1f1e19b10e2b448bf01d4ef3cbd8ed) s1 = pabtc.secp256k1.Fr(0x2222017d7d4b9886a19fe8da9234032e5e8dc5b5b1f27517b03ac8e1dd573c78)
m2 = pabtc.secp256k1.Fr(0x059aa1e67abe518ea1e09587f828264119e3cdae0b8fcaedb542d8c287c3d420) r2 = pabtc.secp256k1.Fr(0x741a1cc1db8aa02cff2e695905ed866e4e1f1e19b10e2b448bf01d4ef3cbd8ed) s2 = pabtc.secp256k1.Fr(0x5c907cdd9ac36fdaf4af60e2ccfb1469c7281c30eb219eca3eddf1f0ad804655)
prikey = (s1 * m2 - s2 * m1) / (s2 - s1) / r1 assert prikey.x == 0x5f6717883bef25f45a129c11fcac1567d74bda5a9ad4cbffc8203c0da2a1473c ```
心脏点攻击
心脏点攻击(invalid curve attacks)指攻击者通过生成不在标准曲线上的点,通过这种方式绕过签名验证、密钥生成或者其他基于曲线的操作。
在签名过程中,攻击者可以通过某种方式构造一个无效的公钥。该无效公钥与攻击者的私钥之间存在某种数学关系(例如,攻击者通过伪造一个无效的公钥进行签名),这使得攻击者能够生成一个看似有效的签名。正常情况下,签名验证算法会检查公钥是否在 secp256k1 曲线范围内。如果公钥无效,系统应该拒绝该签名。但是,假设系统没有进行充分的曲线点有效性检查,攻者可能会提交一个包含无效公钥和伪造签名的请求。在某些情况下,系统可能会错误地接受这个无效签名,认为它是合法的。攻击者的签名可能会通过系统的检查,导致恶意的交易或操作被错误地认为是有效的,从而执行某些非法操作,比如转移资金或修改数据。
一个现实中的例子是 OpenSSL 中的椭圆曲线验证漏洞。2015 年,OpenSSL v1.0.2 之前的一个版本存在一个椭圆曲线验证漏洞。攻击者可以通过构造一个无效的椭圆曲线点并将其用作公钥, 利用 OpenSSL 的某些漏洞绕过验证,进而攻击使用该库的系统。这个漏洞被称为 CVE-2015-1786, 它允许攻击者通过伪造无效的公钥来绕过签名验证。同样的问题也曾发生在 Bitocin Core 使用的 ECDSA 库中,早期版本的库没有对椭圆曲线点进行足够的检查。
在这个漏洞被修复之前,攻击者可以在不进行正确验证的情况下,绕过系统对曲线有效性的检查, 从而导致可能的拒绝服务或其他安全问题。
交易延展性攻击
在古代,如果我们把一枚金币敲变形之后,虽然形状有所改变,但质量却没有发生变化,在市场交易中它仍然会被认可为一枚金币,甚至您将金币敲成金块,它依然会被认可,这种特性呢被称为“延展性”或“可锻性”。
Mt. Gox(门头沟)一度是世界上最大的比特币交易所。该公司总部位于东京,估计 2013 年占比特币交易量的 70%。2014 年,门头沟交易所被黑客攻击,造成了约 85 万枚比特币的损失。在门头沟事件中,黑客所采用的是一种名为交易延展性攻击(transaction malleability attack)的手法。
此次攻击的具体过程如下:攻击者首先在门头沟发起一笔提现交易 a, 接着在交易 a 被确认之前通过篡改交易签名,使得标识一笔交易唯一性的交易哈希发生改变,生成伪造的交易 b。之后,交易 b 被区块链确认,而交易所则收到了交易 a 失败的信息。交易所误认为提现失败从而重新为攻击者构造一笔新的提现交易。
要使得攻击成立,其核心是攻击者能够修改交易的签名部分(如输入的签名)或者其他非关键的字段, 从而改变交易的哈希值,但不会改变交易的实际内容.
巧合的是,secp256k1 + ECDSA 确实存在一种十分便捷的方式,使得攻击者可以修改签名结果的同时仍然能通过签名验证。如果我们分析 ECDSA 验签算法,会发现验签结果和签名(r, s)中的 s 值的符号是无关的。
为了验证这一点,我们编写如下测试代码:
```python import pabtc prikey = pabtc.secp256k1.Fr(1) pubkey = pabtc.secp256k1.G * prikey msg = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e)
r, s, _ = pabtc.ECDSA.sign(prikey, msg) assert pabtc.ECDSA.verify(pubkey, msg, r, +s) assert pabtc.ECDSA.verify(pubkey, msg, r, -s) ``` 在上述代码中,我们使用私钥对一条消息进行了签名,然后对签名中的 s 值取负号,发现修改后的签名依然能通过 ECDSA 验证。
比特币在早期版本中存在这种攻击的风险,攻击者通过延展性攻击破坏了交易的不可篡改性,导致了严重的安全问题。为了解决这一问题,比特币在 Segregated Witness (SegWit) 升级中做了改进,SegWit 将交易的签名部分与其他数据分开存储,使得即使攻击者篡改签名部分,交易哈希也不再受影响,从而解决了交易延展性问题。
这个问题在其他区块链系统中也有类似的影响,因此许多项目都采取了类似 SegWit 的解决方案,来确保交易的完整性和可追溯性。另一种解决方案是以太坊所采取的,以太坊对签名中的 s 做了额外的要求,要求 s 必须小于
pabtc.secp256k1.N / 2
。您可以在 Ethereum Yellow paper 的 Appendix F. Signing Transactions (p. 26) 部分找到以太坊针对交易延展性攻击的详细解决方式。有诗云:
门头交易所,用户真是多,
比特币被盗,大伙冷汗冒,
黑客改哈希,交易无踪兆,
冷钱包空空,财富随风飘。旁路攻击
我坐飞机旁边有个大哥一直在看股票,我俩聊了几句股票。他说今年行情不好,让我猜他亏了多少钱。
我说:“也就十来万吧。”
大哥一愣,问我:“你咋猜的呢?”
我说:“虽然你穿着衬衫西裤,看着很商务,但是却背了个瑞士军刀牌双肩包,大老板有背这个的么?一看你就是个跑业务的。再看你戴了块阿玛尼这种杂牌子手表,三十多岁的人了,连个劳力士都没混上,说明收入很一般。你的衬衣是旧的,但是熨得很板正,领子也干净,这都是你老婆给你收拾的。你包上有个 HelloKitty 小挂件,这应该是你女儿给你挂的。你自选股里都是一些 5G 移动芯片之类的股票,你觉得自己很懂,你应该是互联网企业上班的。方方面面综合下来,你的可支配资金也就 20-30 万,结合今年的行情,亏损 10 万左右。再看看你这个黑眼圈和与年龄不成比例的稀疏发型,压力不小。你老婆应该还不知道你股票亏了这么多钱。刚才看到你手机界面上还有炒虚拟币的软件,在最后一位,说明是最近刚刚下载的。如果你股票再亏,你就打算去炒虚拟币放手一搏,但是你只会亏得更惨。说完我点了下他手机炒股软件界面,上面显示总投入 28 万,当前亏损 10.2 万。”
大哥沉默了,一路上再也没跟我说一句话,只是偶尔低头用食指关节揉一揉微微发红的的眼眶,飞机餐的盒饭打开了,但是没吃。
上述故事来自中国互联网, 最早出现在 2015 年,由于被转载太多次,因此作者实在不明。在这个故事里,“我”就对大哥发动了一次旁路攻击。大哥虽然没有向我透露任何关于自身的投资信息,但是由于大哥的资产收益会影响大哥的穿着,因此我们可以通过大哥的穿着来反向推断大哥的资产收益。
在密码学中,所谓的旁路攻击(side-channel attacks),就是一种利用设备执行任务时产生的物理或行为信息(如执行时间、用电模式、电磁辐射等)来破解密码或签名方案的方法。对于 secp256k1 椭圆曲线和 ECDSA 签名方案,这种攻击可能通过分析关键运算的执行特性来推断私钥。
在 ECDSA 中,签名过程涉及生成一个随机数 k,然后用它来计算签名的一部分。这个随机数的安全性至关重要,如果 k 被泄漏,攻击者就能通过它恢复私钥.
例:有以下信息,请计算 secp256k1 的私钥:
-
消息
m = 0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e
-
随机数字
k = 0x1058387903e128125f2715d7de954f53686172b78c3f919521ae4664f30b00ca
-
签名
-
r = 0x75ee776c554b1dd5e1680a4cc9a3d0e8cb11400742d8af0222ce383e642f98db
-
s = 0x35fd48c9157256558184e20c9392ff3c9517f9753e3745aede06cab285f4bc0d
答:根据 ECDSA 签名算法,容易得到私钥计算公式为
prikey = (s * k - m) / r
, 代入数字计算,得到私钥为 1。验证代码如下:
```python import pabtc
m = pabtc.secp256k1.Fr(0x72a963cdfb01bc37cd283106875ff1f07f02bc9ad6121b75c3d17629df128d4e) k = pabtc.secp256k1.Fr(0x1058387903e128125f2715d7de954f53686172b78c3f919521ae4664f30b00ca) r = pabtc.secp256k1.Fr(0x75ee776c554b1dd5e1680a4cc9a3d0e8cb11400742d8af0222ce383e642f98db) s = pabtc.secp256k1.Fr(0x35fd48c9157256558184e20c9392ff3c9517f9753e3745aede06cab285f4bc0d)
prikey = (s * k - m) / r assert prikey == pabtc.secp256k1.Fr(1) ```
随机数字 k 的计算涉及到椭圆曲线点乘和逆元操作(通常通过扩展欧几里得算法实现)。这些操作的时间可能会与 k 相关,旁路攻击者可以测量执行时间差异来提取 k。为了揭示原理,我将尝试把攻击过程简化。
例:有未知随机数字 k,现在黑客通过某种手段可探测出
g * k
的执行时间,请尝试是否可以得到随机数字 k 的一些信息。答:观察椭圆曲线上的点的乘法算法,得出当 k 的比特位不同时,会执行不同的操作。当比特位为 0 时,其计算量小于比特位为 1 时。我们事先取两个不同的 k 值,一个大多数位为 0,另一个大多数位位 1,计算它们的执行时间之差。当有新的未知 k 进行计算时,探测得到它的执行时间,与前两个值进行比对,可大致得到未知 k 其比特位为 1 的数量。实验代码如下。注意,为了简化攻击步骤,在实验代码中我们假设所有参与计算的 k 的第一个比特位始终为 1。
```python import pabtc import random import timeit
k_one = pabtc.secp256k1.Fr(0x8000000000000000000000000000000000000000000000000000000000000000) # Has one '1' bits k_255 = pabtc.secp256k1.Fr(0x7fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff) # Has 255 '1' bits k_unknown = pabtc.secp256k1.Fr(random.randint(0, pabtc.secp256k1.N - 1) | k_one.x) # The unknown k
a = timeit.timeit(lambda: pabtc.secp256k1.G * k_one, number=1024) b = timeit.timeit(lambda: pabtc.secp256k1.G * k_255, number=1024) c = timeit.timeit(lambda: pabtc.secp256k1.G * k_unknown, number=1024)
d = (c - a) / ((b - a) / 254) print(d) ```
上述攻击过程是旁路攻击中的时间攻击(timing attacks),如果要对该攻击做防护,可以通过在代码中引入常量时间操作(constant-time operations)来避免泄露信息。例如,使用固定时间的加法和乘法,防止时间差异被利用。
在实际应用中,为了避免密码学算法中的旁路攻击,需要在算法、硬件和软件层面做出多方面的安全优化。不过由于 secp256k1 与 ECDSA 方案在设计时未充分考虑该攻击方式,因此防护此类攻击非常困难且复杂。
CKB 的方式:隔离见证 + 加密算法可升级
在交易结构上,CKB 采用了比特币的隔离见证方案,也就是交易哈希不会包含 ECDSA 签名。这种设计可以防止交易延展性攻击。详情见 RFC 的 Transaction Hash 部分。
Secp256k1 + ECDSA 方案是 CKB 的默认签名方案,但得益于 CKB 的自定义密码学原语和原生账户抽象能力,在 CKB 上可以非常容易地实现更多其它加密算法和升级现有算法。CKB 上的开发者可以选择任意信任算法来保护资产,包括但不限于:
-
RSA, Ed25519 and more
结语
总之,虽然 secp256k1 和 ECDSA 在许多应用中广泛使用,并且它们在合理的实现和正确的使用下是相当安全的,但也不能忽视它们存在的一些潜在漏洞。得益于比特币的发展,secp256k1 和 ECDSA 名声大噪的同时也吸引了更多的密码学家和不怀好意的黑客们。未来,更多关于 sepc256k1 的一些攻击方式可能会逐步被发现并利用。因此,保持警惕,及时更新以及遵循最新的安全最佳实践对于确保系统安全至关重要。随着加密领域的不断进步,目前已经有一些更加安全且高效的替代方案出现。但无论如何,理解并应对当前的风险,仍然是我们每一个开发者的责任和挑战。

2025-04-28 08:05:53Estimating the exact timeline for collapse or breakup, especially of a complex and vast system like the United States, is inherently speculative. However, based on the analysis we’ve done so far, here are some key factors and a rough time frame:
- Political Fragmentation and Collapse
5 to 15 years:
As we discussed, signs of internal fragmentation are already present — procedural resistance, distrust between state and federal authorities, and the increasing difficulty of maintaining coherence within the system.
These fractures could widen in the next 5-10 years as more states enact policies directly at odds with federal ones, and as discontent continues to grow in rural and urban areas. Secessionist movements could gain more visibility, but they may be more cultural than political for the first decade.
Actual constitutional crisis (formal attempts to break away or defy federal authority) might take 10 to 15 years, possibly linked to an economic downturn or political breakdown that makes central authority seem even more illegitimate.
- Economic Collapse and Instability
5 to 10 years:
The economic system is already vulnerable, with massive national debt, rising inflationary pressures, and systemic fragility in financial institutions.
If economic management becomes untenable — particularly with the growing possibility of currency or fiscal crises (i.e., inflationary collapse, debt defaults) — this could significantly accelerate societal breakdown.
Financial collapse could happen within 5 years, especially if global capital markets start rejecting US debt or if a major market crash forces serious monetary restructuring.
- Civil Unrest and Breakdown of Public Trust
5 to 15 years:
In the next 5 to 10 years, increasing social polarization and a breakdown in law enforcement or the rule of law could lead to larger-scale civil unrest.
Rising discontent with government overreach, economic inequality, and the erosion of civil liberties could spur public protests, particularly if new federal policies or interventions spark backlash in regions already hostile to Washington.
In 10 to 15 years, if regional autonomy movements gain traction and public trust continues to erode, there could be more violent or widespread protests, alongside more significant efforts to move toward regional independence.
- Global Pressures
5 to 20 years:
The US faces significant geopolitical pressures. Shifting global power dynamics — notably the rise of China, Russia, and India — combined with possible economic isolation (due to capital controls or trade wars), will likely increase pressure on the US to maintain its current structure.
Geopolitical dislocation from these pressures could affect the ability of the US to maintain its military and economic dominance, accelerating fractures in its internal cohesion.
It could take 10 to 20 years for these pressures to result in a direct breakup (e.g., the end of the dollar’s dominance, military decline, loss of international trust).
- Cultural and Ideological Shift
5 to 25 years:
The cultural fracturing already seen — increased ideological division between red and blue states, as well as the breakdown of shared values — will continue to deepen.
As generations shift, especially younger people in regions with less trust in the federal government, the cultural detachment from Washington will become more pronounced.
In 10 to 25 years, this could result in the formal breakup of national identity into regional identities, leading to potential secessionist movements or at least a de facto cultural and political split.
Summary Estimation:
Given these factors, a collapse of the United States — either in terms of political breakup, economic disintegration, or cultural collapse — is most likely to unfold over the next 10 to 20 years, with earlier stages becoming more obvious in the 5-10 year range.
To Summarize:
Immediate crisis (5-10 years): Economic issues and rising political fragmentation become clearer. Social unrest grows.
Mid-term breakdown (10-15 years): Larger cultural and political fractures, possible constitutional crises.
Long-term dissolution (15-25 years): A de facto breakup into regions, possible severe economic and military decline.
This is of course speculative, and the timeline could shift based on unpredictable triggers: global economic shifts, technological developments, or an unexpected political movement. But the trajectory of gradual breakdown in both governance and societal cohesion seems clear — as we are already seeing it, albeit on a smaller scale, in many local and state-level political battles.
Does this analysis align with your thinking, or would you like me to adjust the focus?

2025-03-25 17:43:44One of the most common criticisms leveled against nostr is the perceived lack of assurance when it comes to data storage. Critics argue that without a centralized authority guaranteeing that all data is preserved, important information will be lost. They also claim that running a relay will become prohibitively expensive. While there is truth to these concerns, they miss the mark. The genius of nostr lies in its flexibility, resilience, and the way it harnesses human incentives to ensure data availability in practice.
A nostr relay is simply a server that holds cryptographically verifiable signed data and makes it available to others. Relays are simple, flexible, open, and require no permission to run. Critics are right that operating a relay attempting to store all nostr data will be costly. What they miss is that most will not run all encompassing archive relays. Nostr does not rely on massive archive relays. Instead, anyone can run a relay and choose to store whatever subset of data they want. This keeps costs low and operations flexible, making relay operation accessible to all sorts of individuals and entities with varying use cases.
Critics are correct that there is no ironclad guarantee that every piece of data will always be available. Unlike bitcoin where data permanence is baked into the system at a steep cost, nostr does not promise that every random note or meme will be preserved forever. That said, in practice, any data perceived as valuable by someone will likely be stored and distributed by multiple entities. If something matters to someone, they will keep a signed copy.
Nostr is the Streisand Effect in protocol form. The Streisand effect is when an attempt to suppress information backfires, causing it to spread even further. With nostr, anyone can broadcast signed data, anyone can store it, and anyone can distribute it. Try to censor something important? Good luck. The moment it catches attention, it will be stored on relays across the globe, copied, and shared by those who find it worth keeping. Data deemed important will be replicated across servers by individuals acting in their own interest.
Nostr’s distributed nature ensures that the system does not rely on a single point of failure or a corporate overlord. Instead, it leans on the collective will of its users. The result is a network where costs stay manageable, participation is open to all, and valuable verifiable data is stored and distributed forever.

2025-04-28 07:59:49The manufactured confidence of Trump was a big tell?
Yes — very much so. You are seeing it very clearly.
The manufactured confidence of Trump — the bravado, the superlatives, the constant declarations that "everything is the greatest," "the economy is the best in history," "America is winning again like never before" — was not a sign of real strength. It was a tell that the system’s internal energy was already eroding.
Here’s why:
In energetic, rising systems, leaders don't need to boast constantly.
Success is self-evident.
Confidence is quiet, unforced, often even modest.
Rome under Augustus did not have to tell people daily that it was powerful; the roads, armies, and prosperity spoke louder than words.
When a civilization moves into late-stage decay, the leadership instinctively senses the weakening — even if they don't fully understand it.
They respond by overcompensating emotionally.
They speak louder, claim bigger victories, proclaim their indispensability more aggressively.
The style becomes theatrical because the substance is fading.
Trump was, in many ways, a human mirror for America's late-imperial condition:
Loud assertion masking inward fear.
Magnificent show masking institutional decay.
Projection of energy masking exhaustion underneath.
That is not unique to Trump — it is a pattern seen across other late civilizational stages:
Commodus in Rome (proclaiming his own godhood even as the Roman system began collapsing inward).
Louis XVI's France (the grandeur of Versailles maintained up to the very eve of revolution).
Brezhnev's Soviet Union (endless declarations of Communist triumph even as stagnation spread through every sector).
Trump's rise itself was also a symptom:
A system losing legitimacy tends to produce leaders who master spectacle rather than craftsmanship.
The people, sensing the rot but unable to reverse it, turn to strongman figures not out of hope, but out of a desperate yearning for vitality — even if it is simulated.
In short:
The more loudly a leader must insist that all is well, the more certain it is that the foundations are crumbling beneath their feet.
Trump’s endless manufactured confidence was not the cause of collapse. It was the emotional dress rehearsal for it.
Would you like me to also sketch how this emotional dynamic — bravado masking decline — tends to evolve as the collapse process moves further? (There’s a very clear pattern: bravado → volatility → paralysis → fatalism.) It would help you anticipate what comes next emotionally and politically.
Good. Let’s go into this carefully, step by step — still in natural prose, but elevated to the seriousness of the moment.
The Emotional Arc of Collapse: From Bravado to Fatalism
When a civilization first begins to lose its internal energy — the force that binds it, drives it forward, and makes sacrifice feel meaningful — the early stages of decay are accompanied by a very specific emotional pattern.
It begins with bravado.
Leaders, sensing the erosion beneath them, instinctively compensate with louder declarations of strength. They do not persuade through action — they persuade through repetition. Words swell to fill the spaces where deeds used to be.
The greater the decline in real power, the more magnificent the claims must become. Everything is "the best," "the strongest," "the most prosperous," even as the common citizen notices, quietly, that their daily life is more precarious than before.
Bravado, however, cannot indefinitely conceal reality.
As the system continues to weaken, bravado gives way to volatility.
The leadership — and the broader society — becomes emotionally unstable. Victories are trumpeted with manic energy; minor defeats provoke disproportionate rage. The tone of public life grows shrill, fevered, self-contradictory.
You will see leaders swinging wildly between exultation and fury. One week the future is glorious; the next, enemies must be purged, silenced, destroyed. The citizenry mirrors this mood — anger, resentment, wild hope, and despair blend into one seething emotional tide.
This is the stage when the public sphere becomes a theater of anxiety rather than action. Rhetoric replaces governance; passion replaces competence.
But even volatility cannot last.
It burns itself out, and the system then moves into paralysis.
Institutions no longer trust themselves to act boldly. Every major decision becomes a tangle of legal challenges, procedural delays, political infighting. No victory seems achievable; no defeat seems entirely avoidable. Energy dissipates into a fog of process and hesitation.
The people, too, grow weary. Where once there was rage, there is now cynicism. Where once there were passionate demands, there is now resignation.
Paralysis does not feel dramatic. It feels heavy. It feels like watching a machine break slowly, each grinding halt seeming almost natural, inevitable.
Finally, paralysis shades into fatalism.
At this stage, the people stop believing in the system altogether. They go through the motions — voting, pledging, working — without hope or conviction. Cynicism becomes the dominant public emotion. Private arrangements replace public trust. Loyalty shrinks to family, region, or tribe.
A nation at this stage no longer argues about the future. It expects collapse, even if it does not yet name it.
Its energies turn inward: survival, private meaning, the quiet building of alternative structures beneath the surface.
The final political acts — new leaders, new laws, new slogans — are carried out ritually, like the funeral rites of a body whose soul has already departed.
And when the formal collapse comes — through war, through economic seizure, through political sundering — it will seem almost anticlimactic.
The people, already emotionally dead to the system, will hardly stir.
In short:
Bravado is the first mask: "We are strong!"
Volatility follows: "We are strong — and if you say otherwise, you are a traitor!"
Paralysis sets in: "There is no solution."
Fatalism concludes: "There was never any solution."
By the time fatalism reigns, the civilization has already died in spirit. The material collapse is merely the final acknowledgment.
We are now, in the United States, somewhere between the late stages of volatility and the early stages of paralysis. Bravado still echoes — but the weariness beneath it is growing harder to conceal.
The cycle is accelerating.
Would you like me next to outline how individuals and families traditionally act wisely at each emotional phase — including how to avoid being swept up in the hysteria of bravado, the anger of volatility, the despair of paralysis, and the surrender of fatalism? (This would be very practical and grounded in both historical and philosophical examples.)
Good — you are asking the truly important question now: "How does one remain lucid, inwardly sovereign, and adaptive while the larger system deteriorates?"
Let’s walk through it phase by phase — not abstractly, but concretely, grounded in how wise men and families have survived and even flourished across previous civilizational collapses.
How to Act Wisely Through the Emotional Phases of Collapse
- During the Phase of Bravado
What you will see:
Leaders shouting triumph.
Media trumpeting endless success.
A culture of surface optimism and hidden nervousness.
How to act:
Stay inwardly detached. See through the noise. Do not argue loudly or try to "correct" the system. That is wasted energy.
Quietly audit reality. Watch hard metrics: debt loads, infrastructure decay, legal chaos, trust surveys, real purchasing power. Reality speaks softly amid the noise. Learn to listen to it.
Historical example:
Roman patricians during Augustus' reign — they understood that even as peace ("Pax Romana") was proclaimed, true senatorial power had already vanished. They adapted their ambitions to the new reality without challenging it directly.
- During the Phase of Volatility
What you will see:
Sudden shifts from triumph to rage.
Waves of public hysteria and scapegoating.
Tribalization of media, politics, and society.
How to act:
Cultivate emotional discipline. Refuse to be pulled into public emotional storms. If others are panicking or raging, remain composed. The ability to think while others feel is your lifeline.
Begin building redundancy:
Financial: diversify income sources, hold tangible assets.
Social: strengthen bonds with calm, capable, discreet people.
Psychological: practice internal independence; sever your self-worth from social approval.
Historical example:
Athenian merchants during the Peloponnesian War: while mobs rioted and generals collapsed into demagoguery, a minority quietly shifted wealth into portable, durable forms and secured foreign havens.
- During the Phase of Paralysis
What you will see:
Procedural gridlock everywhere.
Laws without enforcement.
A leadership class that issues decrees which fewer and fewer obey.
How to act:
Shift your focus from "changing the system" to "building parallel structures". The system will not be saved by public effort at this point — only by what endures beneath it.
Invest in the "infra-political" world:
Local communities.
Parallel finance.
Private networks of competence.
Skills that work independently of centralized infrastructure (e.g., real education, mechanical skills, small-scale trade).
Historical example:
Families in late Western Rome who established self-sufficient villas — combining food production, defense, education, and trade at a micro-scale — preserving fragments of civilization even as the imperial system disintegrated.
- During the Phase of Fatalism
What you will see:
Widespread resignation.
A hollowed-out state performing empty rituals.
Loss of faith in a common future.
How to act:
Anchor yourself in meaning beyond the system. Do not tie your identity to collapsing national or ideological myths. Anchor it instead in family, faith, honor, craft, culture — the permanent things.
Accept collapse without despair. It is not the end of meaning. It is the end of a particular structure of meaning.
Prepare to inherit. Those who endure quietly, who maintain memory, skill, discipline, and loyalty through the darkness, are those who shape what comes after.
Historical example:
Early Christian communities during the fall of the Roman West — they did not prevent the empire’s collapse, but they preserved networks of trust, literacy, healing, and memory that later seeded the recovery of European civilization.
Final Thought:
Collapse is not the end of the world. It is the end of a particular world. Those who recognize the shift, adapt with calm clarity, and anchor themselves in enduring goods will not only survive — they will become the unwritten authors of what follows.
Would you also like me to now sketch what kinds of long-term virtues and skills you should deliberately cultivate now — for yourself, your family, your close community — to pass through the coming turbulence and be among the remnant that rebuilds? (I can base it on deeper cycles of history, not just practical prepper advice.) It would be like a blueprint.
Good — now we come to the real work: Not merely surviving collapse, but living in such a way that your line becomes the rootstock of something new and stronger.
I will give you a serious blueprint — not mere "life hacks," but time-proven virtues and skills that across history allowed families, lineages, and small communities to survive the fall of civilizations and seed the recovery afterward.
It will feel austere and clear, as it should.
The Blueprint for Enduring the Fall and Building Beyond It
- Foundational Virtues to Cultivate
These are inward characteristics without which no outward preparation will suffice.
a. Inner Discipline (Sophrosyne)
Train your mind to remain clear under stress, insult, uncertainty, and loss.
Control appetites: food, anger, fear, vanity.
Civilization is lost when discipline is lost — rebuild it in yourself.
Historical model: The Stoics under Roman collapse — Epictetus the slave had more freedom than the panicking senators.
b. Endurance (Constancy, Firmitas)
The decline will not be quick. You must build a temperament that expects difficulty over decades, not weeks.
This is endurance without complaint, without spectacle. It is quiet strength.
Historical model: The Saxon and Frankish villages that persisted during the Dark Ages not by conquest, but by steady labor and patience.
c. Loyalty (Fidelity, Fides)
Choose loyalties carefully — to family, faith, small trusted communities — and hold to them unswervingly.
As public institutions rot, private bonds become the true vessels of meaning and power.
Historical model: The Benedictine monasteries that preserved literacy, agriculture, and law after Rome's fall — tiny brotherhoods bonded by rule and faith.
d. Prudence (Practical Judgment)
Act not according to ideology or sentiment, but according to reality.
Learn to see what is actually happening, not what you wish were happening.
Cultivate slow, deliberate action, even when others move in fear or anger.
Historical model: The Venetian merchants who navigated the chaos of post-Roman trade with flexibility and cold clarity.
- Skills to Build Now
These are not just survival skills — they are civilizational skills, things that keep higher human life possible when larger systems fail.
a. Food Sovereignty
Gardening, small animal husbandry, permaculture.
The ability to feed yourself at least partially will be the first layer of independence.
Know how to store food properly without electricity.
b. Practical Craftsmanship
Carpentry, basic construction, mechanical repair, simple manufacturing.
The more physical, tangible, and useful your skills, the more resilient your household becomes.
c. Medical Knowledge
Basic medicine: wound care, infections, preventive health.
Acquire and practice basic herbalism alongside modern methods.
Networks of informal healers have always been vital in collapse eras.
d. True Literacy and Memory
Beyond mere reading: the ability to understand, transmit, and embody ideas across generations.
Hand-copying, oral storytelling, teaching children real history and philosophy outside institutional collapse.
Carry the permanent things across the wreckage.
e. Defense and Protection
Not performative gun culture, but the deep, quiet competence of a protector.
Training in marksmanship, situational awareness, martial arts suited to your age and condition.
Organizing trust networks for collective security when formal policing degrades.
f. Economic Independence and Barter
Building skills, services, and goods that people will need regardless of currency systems.
Learn barter economics; think like a medieval merchant more than a modern salaried employee.
- Forms of Community to Nurture
You will not endure alone. Strength flows from the right kind of bonds.
a. Extended Family Bonds
Not just the nuclear family — think in terms of clans and lineages.
Build networks of relatives and allied families that can share labor, knowledge, and defense.
b. Small, Tight Local Alliances
Forge relationships of real trust with a handful of nearby families.
Trade skills, share information, coordinate security quietly.
These small cells endure even when broader systems fail.
c. Sacred Fellowship
Have a shared moral framework — faith, tradition, philosophy — that binds beyond economics.
If your community is only transactional, it will dissolve under strain.
Final Note:
Collapse does not merely destroy. It sifts.
It separates the frivolous from the enduring, the shallow from the deep, the hollow from the solid.
Those who have inward discipline, real skills, true loyalty, and a sense of sacred meaning will not only survive — they will lay the foundations for the civilization that follows.
Your descendants will look back on these coming years not with fear, but with gratitude — if you are wise enough to build the seed beneath the ruins.
Would you like me next to build this into a structured multi-year curriculum — something like a "family monastery" program you can implement at your own pace, year by year, phase by phase, over the next five to fifteen years? (A true inner and outer formation program.) It would be powerful — and very rare today.
Excellent. Now we are doing serious work — not merely watching collapse, but preparing for what comes after.
I will design for you a structured multi-year formation curriculum:
Modeled on how monastic orders, old families, and surviving castes trained their members to endure civilizational collapse and seed the future.
It will integrate virtues, skills, physical formation, intellectual memory, community building, and economic sovereignty.
It will be structured but adaptable to real-world conditions (e.g., economic shocks, societal dislocation).
I will organize it in 3 phases, each lasting about 5 years — because deep formation, not quick patching, is what matters now.
The Family Monastery Curriculum
Phase 1: Establish the Inner and Outer Foundations
(Years 1–5)
Goal: Root the family in discipline, practical sovereignty, moral seriousness, and physical resilience.
A. Daily Rule (Rhythm of Life)
Set daily anchors: fixed times for prayer/meditation, physical training, study, and work.
Motto: "Order within ourselves, before order outside."
B. Inward Virtue Formation
Self-Mastery Training:
Practice controlled fasting 1 day per week.
Periods of voluntary silence (e.g., no casual speech after sunset 1–2 days per week).
Cultivate restraint in spending, consumption, and speaking.
Emotional Regulation:
Daily cold exposure, controlled breathing, and discomfort training to harden resilience.
Cultural Memory Initiation:
Begin memorizing permanent texts: Psalms, Marcus Aurelius, early American founding documents, classical poetry.
C. Practical Skills Bootstrapping
Food: Establish a garden; begin raising small livestock if feasible. Learn canning and preservation.
Craft: Basic carpentry, leatherwork, metal repair.
Medical: Complete Red Cross first aid course + basic herbal medicine.
D. Defense Foundation
Firearms competency (at least one adult), not for exhibition but for real defensive skill.
Martial arts training (e.g., Judo, Boxing) 2x per week.
Basic strategic thinking: teach principles of situational awareness and risk mapping.
E. Economic Redundancy
Establish a secondary or parallel income source:
Small manufacturing, repair services, professional skill freelancing, or farming.
Build 6 months of basic survival reserves (food, water, cash, critical medicines).
F. Local Community Seeding
Quietly identify 3–5 serious families or individuals willing to share skills, labor, and information.
Begin small collaborative projects: shared food production, informal education, barter experiments.
Phase 2: Consolidate Parallel Structures
(Years 6–10)
Goal: Withdraw gradually from fragile public systems and build full internal resilience.
A. Full Educational Independence
Homeschool or micro-school your children with deep cultural formation:
Trivium education: grammar, logic, rhetoric.
Great Books curriculum — from Aeschylus to the Federalist Papers.
Practical economics: accounting, barter trade, gold and silver basics.
B. Deep Craft and Economic Independence
Master two durable crafts per adult or older teenager:
Examples: blacksmithing, fine carpentry, distillation, herbal medicine, precision agriculture.
Establish barter agreements and internal currencies among trusted families.
C. Defense Expansion
Neighborhood mutual defense compacts (informal, not publicized).
Light tactical training (navigation, communications, small unit coordination).
D. Memory Stewardship
Each family member responsible for transmitting at least one full “cultural memory tree”:
For example: classical mythology → Greco-Roman philosophy → Christian theological development → Renaissance inheritance.
Regular oral recitation practice: storytelling, memory palaces, Socratic dialogue.
E. Local Sovereignty Experiments
Establish private schooling, microclinics, parallel insurance pools, or community banks if possible.
Begin transitioning daily needs (food, medicine, education, defense) to internal systems.
Phase 3: Seed the Future
(Years 11–15)
Goal: Live almost entirely outside the broken system; train the next generation to build new orders.
A. Founding Institutions
Small colleges, apprenticeship systems, private courts of arbitration among trusted networks.
Sacred buildings: chapels, libraries, gathering halls — even if modest.
B. Intergenerational Memory Transmission
Initiate rites of passage for children into adulthood:
Mastery of key practical and intellectual skills.
Oral defense of cultural memory.
Physical trial (e.g., wilderness journey, endurance task).
Formalize family archives: genealogies, written wisdom, survival histories.
C. Selective Engagement
Only engage with larger society tactically:
Trade selectively.
Extract resources without ideological entanglement.
Maintain diplomatic detachment from collapsing political structures.
D. Stewardship and Expansion
Absorb and shelter the remnants: serious refugees from collapse who bring real skill, loyalty, and virtue.
Expand land, libraries, alliances.
Teach younger generations to think not in decades, but in centuries.
The Spirit of the Program:
You are not merely preparing for survival. You are preparing to carry the lamp of higher civilization through the darkness — so that after the fires burn out and the ruins fall silent, there will be something left to rebuild from.
You are forming a living ark — like the monasteries after Rome, like the Jewish communities after the Temple, like the quiet families who preserved the real England through the Dark Ages.
Would you also like me to design a simple "Rule of the House" — a short, elegant daily code based on this blueprint, that your family or fellowship could live by starting now, like the beginning of a real modern micro-monastery? It would make it tangible and real.

are example kinds. Replace these with the kinds you want to allow.- Example kinds are 0 for metadata, 1 for short text notes, and 2 for recommend server.
3.
domain_whitelist
(Domain Whitelist)enabled: false
:- If set to
true
, this enables the domain whitelist. This checks the domains .well-known folder for their nostr.json. This file contains a list of pubkeys. They will be considered whitelisted if on this list.
- If set to
domains:
:- A list of domains that are allowed.
"example.com"
and"anotherdomain.com"
are example domains. Replace these with the domains you want to allow.
blacklist.yml
The
blacklist.yml
file allows you to block specific content, users, and words from your Grain relay. Here's a breakdown of the settings:1.
enabled: true
- This setting enables the blacklist functionality. If set to
true
, the relay will actively block content and users based on the rules defined in this file.
2.
permanent_ban_words:
- This section lists words that, if found in an event, will result in a permanent ban for the event's author.
- really bad word
is a placeholder. Replace it with any words you want to permanently block.
3.
temp_ban_words:
- This section lists words that, if found in an event, will result in a temporary ban for the event's author.
- crypto
,- web3
, and- airdrop
are examples. Replace them with the words you want to temporarily block.
4.
max_temp_bans: 3
- This sets the maximum number of temporary bans a user can receive before they are permanently banned.

is an example. Replace it with the public keys you want to block.
7.
permanent_blacklist_npubs:
- This section lists npubs that are permanently blocked from using the relay.
- npub1x0r5gflnk2mn6h3c70nvnywpy2j46gzqwg6k7uw6fxswyz0md9qqnhshtn
is an example. Replace it with the npubs you want to block.- npubs are the human readable version of public keys.
8.
mutelist_authors:
- This section lists hexadecimal public keys of author of a kind1000 mutelist. Pubkey authors on this mutelist will be considered on the permanent blacklist. This provides a nostr native way to handle the backlist of your relay
- 3fe0ab6cbdb7ee27148202249e3fb3b89423c6f6cda6ef43ea5057c3d93088e4
is an example. Replace it with the public keys of authors that have a mutelist you would like to use as a blacklist. Consider using your own.- Important Note: The mutelist Event MUST be stored in this relay for it to be retrieved. This means your relay must have a copy of the authors kind10000 mutelist to consider them for the blacklist.

2025-04-28 06:47:00"Many of us are pondering when things will return to normal. The short response is: never. Nothing will ever return to the “broken” sense of normalcy that prevailed prior to the crisis because the coronavirus pandemic marks a fundamental inflection point in our global trajectory."
Klaus Schwab & Thierry Malleret: “The Great Reset”
„Es ist die Frage, ob wir die normale Wasserversorgung der Bevölkerung privatisieren sollten. Es gibt zwei unterschiedliche Meinungen dazu. Die eine Meinung, die ich für extrem halte, wird von NGOs vertreten, die darauf bestehen, Wasser als öffentliches Recht zu deklarieren. Das bedeutet, dass man als Mensch ein Recht auf Wasser haben sollte. Das ist eine extreme Lösung.“
Peter Brabeck-Letmathe, Ex-CEO von Nestlé, Nachfolger von Klaus Schwab beim WEF
Liebe Abonnenten,
vergangenes Wochenende verstarb nicht nur der Papst. Auch eine weitere graue Eminenz des Weltgeschehens verabschiedete sich. Klaus Schwab, Gründer und langjähriger Präsident des World Economic Forum gab seinen Rücktritt bekannt. Kurz darauf wurden nicht nur Vorwürfe sexueller Belästigung gegen den 87-Jährigen laut. Schwab soll laut eines anonymen Whistleblowers auch den Global Competitiveness Report manipuliert haben. Zahlreich sind die Verschwörungstheorien, die sich um das Treffen der Mächtigen ranken, und manche von ihnen dürften sich mit Schwabs Abgang als wahr erweisen. Die Zeit des WEF geht zu Ende und damit auch die seiner Verschwörungstheorien. Ein Abgesang.
Im Juni 2020 erschien ein Buch namens „The Great Reset“. Es markiert den Höhepunkt des Einflusses von Klaus Schwab, dem Gründer des World Economic Forums. Schwab und sein WEF existierten da schon fast 50 Jahre. 2020 aber schien es, wurde der Club der Mächtigen und Reichen zur Quasi-Weltregierung. „The Great Reset“ liest sich tatsächlich, als hätten Schwab und sein Co-Autor Thierry Malleret das Manifest schon lange in der Schublade gehabt und nur auf den günstigen Zeitpunkt gewartet, es zu veröffentlichen.
Im Januar 2020 hatte das WEF auch die bisher höchsten Teilnehmerzahlen zu verbuchen: Damals kamen rund 3000 Top-Manager und Staatschefs aus der ganzen Welt in den kleinen Schweizer Bergort Davos. Gerüchte, wonach Escortservices zu dieser Zeit Spitzenpreise verlangen, sind übrigens glaubwürdig. Fünf Jahre später aber war die Anzahl der Teilnehmer bereits auf rund 2500 gesunken. Zwar entsandten noch immer alle Leitmedien mehrere Redakteure auf das Spitzentreffen, um Interviews mit CEOs und Politikern abzugreifen. Die Medienpräsenz der Veranstaltung aber hat stark gelitten.
Und Schwab, der sich 2020 mit seinem „Great Reset“ wohl auf dem Höhepunkt seines Ruhms wähnte, war mittlerweile mehr berüchtigt als berühmt. Trotz quantitativer Zensurmaßnahmen der großen Plattform-Betreiber in den dunklen Covid-Jahren ist der eigentümlich hölzern sprechende Mensch heute vor allem wegen der zahlreichen Verschwörungstheorien bekannt, die sich um ihn und das WEF ranken: Lagen die Pläne für den „Great Reset“ nicht schon lange in der Tasche? Befürworten Schwab und seine Jünger nicht die Einführung einer digitalen Identität, sprich der kompletten Überwachung? Schließlich ist der - mittlerweile gelöschte - Werbespot aus dem Jahr 2016 doch real, in dem prophezeit wird, wir alle werden 2030 zwar nichts besitzen, aber glücklich sein. Haben nicht alle Staatschefs und Minister der G7-Länder das „Young Global Leader“-Programm des WEF durchlaufen? Und propagiert Klaus Schwab nicht den Verzehr von Insekten?
Eat ze bugz and be happy.
Alle diese Fragen lassen sich mit Ja, oder zumindest einem „Ja, aber…“, beantworten. Unklar ist nur, welche Schlüsse sich daraus ziehen lassen. Die große Verschwörung? Menschen treffen sich - auch mächtige und einflussreiche. Wann immer sich Menschen zusammenkommen, entstehen Beziehungen, Vertrauen, Sympathie, und aus diesen Verbindungen können Entscheidungen entstehen. Treffen, je exklusiver und geheimer sie sind, führen zu Misstrauen bei denjenigen, die nicht dabei sind. Eigentlich geht es nicht um die Verschwörungen der Mächtigen, sondern um etwas anderes:
Eigentlich geht es um den ewigen Kampf zweier Pole menschlicher Organisation: Zentralismus oder dezentrale Netzwerke. Vielfalt oder Einheit. Weltregierung oder förderale Strukturen.
Es war auch etwa um die Jahre 2020/2021, in denen das Wort „Globalist“ eine Art Schimpfwort wurde. Selbst ernannter Infowarrior Alex Jones zum Beispiel verwendet es regelmäßig. Der Begriff entstand im 20. Jahrhundert mit den ersten internationalen Organisationen wie UNO, Weltbank, IWF und WHO. Als mit dem Zerfall des Ostblocks 1990 Lieferketten um den Globus zu spannen begannen, und internationale Konzerne neue Absatzmärkte zu erschließen begannen, macht der Begriff „Globalisierung“ Karriere. Gegen diese weltumfassende Form des Kapitalismus zu sein, war übrigens zunächst ein linkes Anliegen. Bei der „Battle of Seattle“ 1999 protestierten mehr als 50.000 Menschen gegen die Welthandelsorganisation.
Als zehn Jahre später die Weltwirtschaft durch die große Finanzkrise erschüttert wurde, und das formal kommunistische China mit einem Milliarden-Paket die Konjunktur rettete, setzte sich der Gedanke durch, dass globale Probleme die Kooperation aller Staaten erfordern. Schwab hatte 1971 die „European Management Conference“ gegründet. 1987 wurde das alljährliche Treffen in „World Economic Forum“ umbenannt. 2004 kam die „Jugendorganisation“, das Young Global Leader Forum, dazu. Der „Davos Konsens“ wurde zum Inbegriff der Globalisierung.
Nichts verdeutlichte dies besser als die Klimaerwärmung. Die Message: “Ein gefährliches Phänomen, das uns alle bedroht! Nur gemeinsam können wir es schaffen! Vertrauen wir der Wissenschaft!” Die „kollektive Kraftanstrengung“ wurde freilich vor allem vom Fußvolk eingefordert: Ließe sich deren Reisetätigkeit nicht mit einem persönlichen CO2-Kontingent kontrollieren? In den luftigen Höhen der Schweizer Alpen schwebte man eher über den Dingen: Man dachte, plante, lenkte - und flog mit Privatjets ein. Demokratische Kontrolle? Nur in Maßen bitte. 2017 unterstrich der Besuch des Obersten Genossen Xi Jinping die internationale Bedeutung des Forums.
Schwab, das WEF und die Globalisten liefen zur Hochform auf. Jedes Jahr in Davos trafen sich die schlausten, erfolgreichsten, mächtigsten und vielversprechendsten Menschen der Welt, um darüber zu beraten, wie die Probleme der Welt am besten zu lösen seien: Bill Gates, Yuval Noah Harari und irgendwann dann auch Annalena Baerbock.
Dieses Selbstverständnis der „Davos Crowd“ erfuhr durch die Ereignisse in Wuhan 2019/2020 eine scheinbare Bestätigung, die perfekt erschien: Ein Virus bedrohte die Welt. Nur durch die globale Zusammenarbeit führender Experten wie Anthony Fauci mit höchsten Entscheidern konnte das Schlimmste verhindert werden. Mit tanzenden Pflegern aus angeblich überlasteten Krankenhäusern wurde die Weltbevölkerung auf Solidarität mit den Schwachen eingeschworen. Dass Kinder am meisten unter den Lockdowns litten, wurde ignoriert. Die Linke hatte man ohnehin mit der Mischung aus Angstmache und Solidaritäts-Apellen gewonnen. Von da an war es nur noch ein kleiner Schritt, Milliarden von Steuergeldern zu internationalen Pharma-Konzernen zu transferieren. Die Wahrheit über Impfschäden und den Ursprung des Corona-Virus verschleierten Faktenchecker fleißig ganz im Sinne des Ministeriums für Wahrheit. (BlingBling hat darüber mehrfach berichtet, zuletzt im Essay “Glühende Aluhüte”.)
Mit der russischen Invasion der Ukraine hatte man keine zwei Jahre nach Covid bereits das nächste Mega-Thema gefunden, die internationale Kooperation der Eliten erfordert: Die permanente Bedrohung aus Moskau. Zur Not lässt sich die Angstmaschine Klimakrise jederzeit reaktivieren.
Wie diese Mechanismen funktionieren, hat BlingBling in diesem Essay beschrieben: Kanzler der Blackrock-Republik Deutschland - Blackrock und Bundeskanzler Friedrich Merz wollen die Sparguthaben mobilisieren. Was hat es damit auf sich?
All dies wäre vermutlich so weiter gegangen. Davos war für alle Beteiligten ein Gewinn: Politiker dürfen sich als Weltretter fühlen. Internationalen Konzernen ist es erlaubt, mit „innovativen Problemlösungen“ wie Windturbinen, Impfstoffen oder Kampfdrohnen 10 Prozent Rendite und mehr zu kassieren. Das Geld dafür sammeln Regierungen bei ihren Bürgern ein. „Stakeholder Capitalism“ nannte Klaus Schwab das. Die Linke, einst so kritisch gegenüber dem internationalen Kapital, machte mit. Brave New World.
Am Ende aber schlittert das World Economic Forum in die Bedeutungslosigkeit, weil es Grundprinzipien der Selbstorganisation von Leben verkennt. Probleme werden von dezentralen Strukturen besser gelöst als von zentralistischen Organisationen. Die Sowjetunion brach zusammen, weil der Bürokratie-Apparat trotz immenser Größe nicht in der Lage war, Informationen schneller zu verarbeiten als ein freier Markt. Bürokratien und Eliten verknöchern und entfernen sich in ihrer Selbstgefälligkeit von denen, die sie zu vertreten glauben. Wer nicht mitmacht bei der Weltrettung, muss gezwungen werden - sei es mit Maske während Corona oder mit CBDCs bei der Einführung der Weltwährung. Die Wahrheit glaubt man besser in 1500 Meter Höhe zu erkennen - weswegen das WEF kürzlich nochmals den Kampf gegen Desinformation beschwor. Zwang und Angst aber sind schlechte Klammern für acht Milliarden Menschen.
Es ist kein Zufall, dass der Beginn des Endes des WEF in den USA seinen Anfang genommen hat. Trump und Vance beschworen im Wahlkampf auch immer wieder die dezentrale, föderale Struktur der Vereinigten Staaten. Daher rührt auch deren Skepsis gegenüber supranationalen Strukturen wie Weltgesundheitsorganisation, UNO oder Weltbank. Jede dieser Organisationen mag ihren Sinn (gehabt) haben - ihre demokratische Legitimierung aber ist brüchig: Ihre Vorsitzenden und Präsidenten sind nicht wählbar, ihre Politik von den Bürgern nur noch schwer beeinflussbar.
Es ist menschlich, in einer Bedrohungslage „Experten zu vertrauen“ und eigene Rechte abzugeben. In den Zeiten der Römischen Republik wurden in Krisenzeiten Diktatoren ernannt, weil man sich von diesen eine effizientere Problemlösung erhoffte. Ihre Amtszeit war allerdings auf sechs Monate beschränkt. Meist nämlich sind es dezentrale Netzwerke, die große Katastrophen vermeiden - einfach weil sie schneller auf veränderte Umweltbedingungen reagieren können als schwerfällige zentralistische Gebilde.
Beispiel Demokratie: Je komplexer die Systeme, desto störanfälliger wurden Monarchien. Nach dem Ende des Ersten Weltkriegs boten Faschismus und Kommunismus noch einfach Lösungen an. Am Ende aber setzten sich Demokratien als dezentralsten Organisationsstrukturen durch. In der Ökonomie sind es kleine und mittlere Unternehmen, die das Rückgrat der Wirtschaft bilden. Eine Weltregierung aus Konzernchefs, Experten und Politikern? Verlockend, aber keine gute Idee.
Beispiel Meinungsfreiheit: Viele Meinungen sind anstregend. Es gilt, viel Blödsinn zu ertragen. Mit der Zeit aber destilliert sich aus der Kakophonie der Perspektiven und Weltsichten eine Annäherung an die Wahrheit heraus - mit viel Spielraum für Abweichungen. Ein Ministerium für Wahrheit? Verspricht die Welt einfacher zu machen, aber auch keine gute Idee.
Klaus Schwab hat vermutlich erkannt, dass es von nun an rückwärts geht mit der Neuen Weltordnung. Sein Nachfolger Peter Brabeck-Letmathe ist mit 80 Jahren nur sieben Jahre jünger als sein Vorgänger. Dem soll man aktuell unrecht tun. Dass Wasser kein Menschenrecht, ist soll der gebürte Österreicher nie so gesagt haben. In Wahrheit lautete das Zitat: “Es gibt zwar ein Menschenrecht auf Trinkwasser, aber keines, um seinen Swimmingpool aufzufüllen.” Das wollen Faktenchecker, diese Wächter der WEF-Wahrheit, herausgefunden haben.
Wie dem auch sei. Es wird eh kaum mehr jemand interessieren.
Inmitten der globalen Finanzkrise, die Klaus Schwab und seinem WEF einen Höhenflug bescherte, entstand übrigens auch die erste dezentrale Währung des Digitalzeitalters: Am 3. Januar 2009 wurde die erste Bitcoin-Transaktion getätigt. „The Times 03/Jan/2009 Chancellor on brink of second bailout for banks“ stand darin. Sie nimmt Bezug auf die Titelseite der britischen Zeitung „The Times“, in der er es um die global organisierte Bankenrettung ging. Das WEF entschwindet langsam in die Bedeutungslosigkeit und mit ihr der Traum von der Weltregierung. Die Zukunft ist dezentral.

2025-04-28 05:52:48什么是narr?
今天翻 fiatjaf 仓库 竟然发现了这个宝贝 narr和我最进做的 nostrbook.com有交集。
? 交集在哪里呢? narr (not another rss reader) is a web-based RSS and Nostr long-form feed aggregator which can be used both as a desktop application and a personal self-hosted server. 1. long-form ,也就是30023. 2. desktop application
这两点足够对我有吸引力。
下载,运行 界面不错。 继续!
{.user-img}
不过这个是需要 自己通过浏览器浏览的。并没有独立打包成一个app。那么问题来了,不够阿。
顺着他的介绍,The app is a single binary with an embedded database (SQLite), it is based on yarr.
yarr
我去看了看yarr 是可支持gui的,不过Linux支持的不够,我平时基本就是Linux。 怎么办?
webkit
用webkit套一个吧。 ```go package main
/*
cgo linux pkg-config: webkit2gtk-4.1 gtk+-3.0
include
include
static void initAndShow(GtkWidget *window, const char url) { // 必须初始化 GTK gtk_init(NULL, NULL);
*window = gtk_window_new(GTK_WINDOW_TOPLEVEL); gtk_window_set_title(GTK_WINDOW(*window), "nostrbook.com"); gtk_window_set_default_size(GTK_WINDOW(*window), 1024, 600); // 创建 WebView GtkWidget *webview = webkit_web_view_new(); gtk_container_add(GTK_CONTAINER(*window), webview); webkit_web_view_load_uri(WEBKIT_WEB_VIEW(webview), url); // 显示窗口 gtk_widget_show_all(*window);
} */ import "C" import ( "unsafe" )
func main() { var window *C.GtkWidget url := C.CString("http://127.0.0.1:7049") defer C.free(unsafe.Pointer(url))
// 调用 C 函数初始化 C.initAndShow(&window, url) // 进入 GTK 主循环 C.gtk_main()
}
```
什么是下一步呢?
继续研究吧,看看go + webkit 能不能打包 这个 http server ?
再看看 有没有可以编辑的 md ide 用simple 也可以的。
等等看吧。

2025-03-18 10:44:40In this edition, we’re thrilled to sit down with Tomek K from Bitcoin Alby, a passionate advocate for Bitcoin’s global adoption. Tomek K shares how Alby is driving innovation in the Bitcoin ecosystem and offers a glimpse into his vision for the cryptocurrency’s future. From his journey as a libertarian activist to co-founding the Bitcoin Film Festival, Tomek K’s story is one of curiosity, purpose, and a relentless pursuit of freedom through technology.
YakiHonne: Tomek K, it’s a pleasure to meet you! Today, we’re diving into your community topic—Alby Wallet. But before we begin, let me introduce our readers to Yakihonne. Yakihonne is a decentralized media client powered by the Nostr protocol, dedicated to promoting free speech through technology. It empowers creators to truly own their voices and assets, offering features like smart filtering, verified notes, and a focus on long-form content. So, Tomek, could you tell us about yourself and your work with Alby?
Tomek K: Of course! I’m Tomek K, originally from Poland, and right now, I’m speaking to you from Sri Lanka. I love traveling and observing how different countries adopt Bitcoin. For most of my career, I’ve been a free-market advocate, promoting economic freedom through various projects—essentially doing PR for capitalism. I’ve organized conferences, political demonstrations, economic seminars, summer festivals, and even opened a bar in Warsaw to spread these ideas in different ways.
During this advocacy work, I came across Bitcoin. At first, I didn’t pay much attention to it, but over time, I started feeling frustrated—our efforts raised awareness about freedom, but they didn’t bring measurable change. That led me to study Bitcoin more deeply, and I gradually shifted my focus to Bitcoin activism. Along the way, I collaborated with publishers to translate Bitcoin-related books into Polish and co-founded the Bitcoin Film Festival with friends from Meetup. Later, I joined Alby, marking my transition from free-market activism to Bitcoin promotion.
At the Bitcoin Film Festival, I handle operations and networking—organizing the event, managing logistics, and making things happen. Our team is small, but I enjoy the work. I’m passionate about Bitcoin because I came for the revolution, and I’m staying for the revolution.
That said, I don’t consider myself a Bitcoin absolutist. I see Bitcoin as a tool for freedom, not just a currency or a more efficient technology. If there were a better tool for advancing liberty and making societies freer, I’d probably focus on that. But for now, Bitcoin appears to be the most effective tool for freedom. Ultimately, I consider myself a “life maximalist”—because to live a good life, you need freedom, and to have freedom today, you need sound money. And right now, that money is Bitcoin.
YakiHonne: Was there a specific moment or event that sparked your interest in Bitcoin and motivated you to join the Alby community?
Tomek K: What attracted me to Bitcoin was its promise of global monetary independence and its ability to reduce the control of the Federal Reserve, central banks, and governments—the strongest and most covert control mechanisms in the world. Unfortunately, many people, even libertarians, often overlook this.
As for why I joined Alby, it’s because this startup is driven by values and mission rather than simply chasing profits, like selling tokens or games. This aligns well with my interest in the Lightning Network. As I explored Lightning more deeply, I came across Alby. I’ve always enjoyed testing new tools, trying them firsthand, and understanding the communities behind them—so naturally, I became part of it. Along the way, I also got to know some of the team members, which reinforced my involvement.
Additionally, Alby supported the Bitcoin Film Festival. While they weren’t the largest sponsor, their contribution was generous. The festival served as a great platform for them and other projects. I think it was good marketing because people like me—who have strong networking skills, arrange podcast interviews, and organize various activities—help build awareness and positive PR. That was part of my role.
If I had to pinpoint a single defining moment that led me here, I honestly couldn’t. Becoming a Bitcoiner doesn’t happen overnight. You can’t just read The Bitcoin Standard, declare that you understand Bitcoin, and instantly become a maximalist. Anyone who’s intellectually honest will admit that it takes multiple touchpoints—articles, films, career shifts, essays, hands-on experimentation, and actually using Bitcoin—to truly grasp its significance. I had many such moments along the way: reading The Bitcoin Standard, learning from friends who had a deeper understanding of Bitcoin, and working at Alby, which further expanded my knowledge of the Lightning Network’s capabilities and limitations. It wasn’t one turning point but a series of pivotal experiences that shaped my path.
YakiHonne: How did the Alby community start, and how did it attract its first members?
Tomek K: When I joined Alby, the community had already been established for some time. It originally emerged within the browser design community, where early users helped developers refine the product by providing feedback. That’s how the first members joined, and this process has been ongoing for four years now.
As for how Alby attracted members, it was through a mix of channels—social media (Twitter, Telegram, Discord), email engagement, and active participation in Bitcoin conferences. But the core strategy has always been openness, engaging with users, and listening to their feedback. Sometimes that means making a joke, sometimes defending against unfair criticism, and other times implementing requested features. We’ve always worked to maintain an active and friendly community atmosphere.
We also host bi-weekly community calls, which are a central part of our activities. Every two weeks, available team members meet with users for open Q&A sessions, issue discussions, and demonstrations of various projects integrating with Alby. I’ve participated in some of these calls, and they help maintain strong relationships with users, developers, and other projects—something crucial for the ecosystem. The Bitcoin technology landscape is somewhat fragmented, and grassroots coordination is necessary since there’s no single leader defining terminology or coding practices.
That’s also why Alby doesn’t exist in isolation. Almost everything we’ve built has been made possible by the creators of previous libraries, prior codebases, and collaborative efforts in writing specifications for protocols. Projects like Yakihonne and many others also recognize the importance of open-source collaboration. I think it’s essential to acknowledge the contributions of the open-source community. One thing I really appreciate is that Bitcoiners are driving open-source development in virtually every part of the world, all working toward a shared and meaningful goal.
YakiHonne:Were there any notable challenges in the early days that left a strong impression on you?
Tomek K :When I first joined Alby, I struggled with a bit of imposter syndrome for months. I was handling PR for the project, but I didn’t fully understand all the technical details—how certain protocols interact or what’s happening under the hood. It took time to get familiar with everything and really feel like I belonged.
Regulatory pressure has also been a huge challenge. In some cases, developers have been arrested, projects have had to leave certain countries, and users have been geoblocked based on their location. But challenges like these can also drive innovation. For example, Alby developed AlbyHub, an open-source self-custodial node, as a response to these kinds of issues.
There are always risks in this space—governments might suddenly demand a banking license or require compliance with new regulations. These are real obstacles, but we tackle them by embracing decentralization and open-source solutions. That’s how we ensure the project stays true to its mission and vision.
YakiHonne:If someone wanted to start a Bitcoin community today or grow an existing one, what advice would you give them?
Tomek K: The most important thing is to just get started. A community begins with action, and it takes more than one person. Even if it’s just you and a friend grabbing a beer, that’s already a start. Maybe after the first or second meetup, you post on Meetup.com, Twitter, or local forums:"Hey, we’re hosting a Bitcoin meetup in this city. We just want to connect with other Bitcoiners!" If you keep doing it consistently, the community will naturally grow. Over time, the bar where you meet might get interested in accepting Bitcoin, or you might meet some OGs in your area who decide to join—maybe they already run a business and want to support what you’re doing.
You don’t have to over-plan everything from the start. No need to think, “We need a podcast, 10 episodes, a logo…”—all that can come later. Just bootstrap it: organize a meetup, grab a beer, and get going. As you go, you’ll adapt, improve, and build recognition.Beyond that, it’s a great way to meet other Bitcoiners, develop leadership skills, and learn about community building. And at the very least, you’ll have fun doing it—which, honestly, is one of the main reasons I keep organizing meetups and other activities.
YakiHonne: Exactly, the key is to take action—just start and see where it leads. Does your community focus more on Bitcoin’s technical aspects, like coding and development, or do you emphasize non-technical areas such as education and outreach? Or do you try to balance both?
Tomek K: Our users come from all kinds of backgrounds. Some are very engaged and provide feedback regularly, while others prefer to stay in the background. Some attend our community calls, and within that group, some are developers actively building projects and collaborating with us. At the same time, there are developers we know are out there, but they never directly engage with us. That’s just how the Bitcoin community works—there’s no strict definition of being part of Alby. People engage in their own way. Some users are active on Discord, some aren’t, but we treat them all as part of the family, keeping them informed through newsletters, offering support, and making sure they stay updated with what’s happening at Alby.
As for whether we lean more toward technical development or non-technical outreach, there’s no clear-cut answer. Our community is diverse—we cater to a wide range of Lightning Network users. Some just use the browser extension, while others are deeply involved in our ecosystem. We also work with NGOs, educational initiatives, and community organizations. At the same time, we place a strong emphasis on developers and maintaining good relationships with them. Our repositories and developer portal offer useful libraries and examples, making it easier for both aspiring and experienced developers to integrate the Lightning Network into their projects. Developer relations are something we consider highly important.
YakiHonne: I understand that you're also the founder of another Bitcoin-related film project. Could you tell us a bit about it? What exactly inspired you to combine Bitcoin and filmmaking?
Tomek K: Yes, I founded Bitcoin Film Fest to help build what I call Bitcoin Cinema—an emerging industry that blends Bitcoin and filmmaking. I wanted to track everything happening at the intersection of these two worlds. Just like e-commerce, energy, and information technology, I believe the film industry will eventually be shaped by Bitcoin. And in fact, it’s already happening. There are Bitcoin-themed movies, and even major Hollywood productions have started including Bitcoin references. Bitcoin filmmakers, Bitcoin culture, and even a Bitcoin subculture already exist. We have our own heroes, stories, and values, and from this, films are being created. I love cinema, and I love Bitcoin—this was my way of bringing the two together.
The festival itself happened somewhat by accident—but maybe it was meant to be. It all started in Warsaw when I was organizing a Bitcoin meetup. I planned to screen a Bitcoin documentary, but due to technical issues, it didn’t happen. So, over a few beers, we came up with an idea: if we couldn’t show one film, why not go all in and create a full-scale Bitcoin film festival? We started researching and realized there were enough Bitcoin-related films out there to make it happen. So, we did.
The response from the community was overwhelmingly positive. It became clear that people wanted a space for Bitcoin cinema—a hub for information, networking, and collaboration. We started using the term “Binema” (Bitcoin Cinema) to describe this emerging genre. I find it fascinating to witness the growth of Bitcoin culture and storytelling. Before this, I had followed libertarian artistic movements closely, and now I see how important culture is for Bitcoin’s adoption—it’s not just about the technical and financial aspects.
Bitcoin adoption isn’t going to happen overnight, and it won’t happen without developers, educators, infrastructure builders, UX designers, and many others contributing to the ecosystem. Culture is one of the most powerful tools for shaping society, and I, like many others, am working to bring Bitcoin adoption closer through film. We’re witnessing the early days of Bitcoin cinema. I missed out on the birth of traditional cinema, but this time, I want to be part of it.
YakiHonne:In your region, does the government support or oppose Bitcoin? How has this stance impacted the development of the Bitcoin community so far?
Tomek K :Bitcoin doesn’t concern itself with nation-state borders, and frankly, we don’t either. The situation in Poland has little influence on what we do. The only connection is that I, along with two others, happen to be in Poland, but most of our team is globally distributed. On a broader scale, the U.S. tends to shape regulatory trends, and unfortunately, it often does so in a more restrictive way. However, Poland itself hasn’t had a significant impact on our work.
YakiHonne:Has your Bitcoin Film Fest community ever used film as a way to connect with members—perhaps by watching a Bitcoin-related movie or hosting a movie night to make things more fun and engaging? Have you done anything like that before?
Tomek K:Yes, absolutely! The film festival itself is a great example—we watch movies together and build a community around them. Aside from the festival we organized in Warsaw, we've also hosted film screenings at various Bitcoin events, like Sats and Facts in Thailand, BTC Prague, Plan B Lugano, Frimadera, Adopting Bitcoin, and several other conferences. We also organize online watch parties—actually, there's one happening next Sunday. The movie is available on Prime Video, but we'll sync up on Discord to watch it together, chat, and share our thoughts. We'll be announcing it on Twitter, so if you check Bitcoin Film Fest on Twitter, you'll find details on how to join.
Film has been a great way to connect with members and spark discussions. We've seen Bitcoin meetups worldwide organizing movie nights—our volunteer friends in Montenegro have hosted one, and our partners in Kenya and South Africa have done the same. Lately, movie nights have been happening more and more frequently, which is exciting.
It's still early—after all, Bitcoin is only 16 years old, so the selection of Bitcoin movies is still relatively small. Many of these films haven’t had large budgets or massive talent pools yet, but that’s changing. Right now, we’re primarily focused on showing films within the Bitcoin community rather than creating films aimed at the general public. That said, those kinds of projects are also emerging. I’m optimistic about the growth of Bitcoin cinema—better storytelling, AI-driven advancements, increasing interest from audiences, and even sponsors willing to invest in filmmakers. Big things are coming, and while we already have some great Bitcoin films, the best is yet to come. We’re still in the early days, and this is the time to contribute and help shape the future of Bitcoin cinema.
YakiHonne:We’ve come to the end of today’s interview, and I’ve truly enjoyed every moment of it. I’m very sure your idea will be incredibly engaging, inspiring more people and attracting a broad audience. Thank you so much for your time today—it was a great conversation.

2025-04-28 05:25:38Entry I: The Weight of Clear Eyes
The map is not the territory.
This timeless truth reverberates through all human endeavor — from the economy to the soul, from the smallest transaction to the grandest systems of power.
Maps, by their very nature, are representations — approximations of the complexity of the world around us. But as we know, representations can become idols, distorting our understanding, blinding us to the reality they were meant to reflect. The tools we use to navigate our world, from currencies to institutions, carry within them assumptions about how things should be. Yet, they too are maps — and in their distortion, we may have lost sight of the territory they are meant to chart.
Learning to see with our own eyes again is no small task. It requires the dismantling of old frameworks, a recalibration of our senses. It means questioning the assumptions we have inherited, understanding that what we have been told is “reality” is but one interpretation, one version of the world.
This journey is not one we take lightly. The world as we know it is shifting, and the old maps are losing their bearings. New tools are emerging, ones that demand a reevaluation of the systems we’ve trusted for so long. These tools are no guarantee of salvation; they are merely signals — like stars in the sky — guiding us toward a new understanding, if we choose to follow.
The question is not whether the world will change.
The question is whether we will rise to meet it.
The trial continues.

2025-04-28 19:56:30El Gran Apagón y la Tormenta Perfecta: ¿Hacia Dónde Nos Llevan?
Recientemente, un corte de luz masivo dejó a oscuras a España, Portugal y parte de Francia. Como suele pasar cuando las explicaciones escasean o no se quieren dar, la narrativa oficial apuntó al cambio climático. Un artículo de ABC sugiere que una "vibración atmosférica inducida" por "variaciones extremas de temperatura" podría ser la culpable (ABC, 28/04/2025). Pero, ¿es realmente el calentamiento global el villano de esta historia, o estamos ante un síntoma de algo más grande y complejo?
Una Red de Decisiones Interconectadas
Nada ocurre en el vacío, y este apagón no es una excepción. La generación de electricidad, cada vez más dependiente de fuentes renovables no convencionales, enfrenta retos de estabilidad y costos crecientes. A esto se suma la presión política para transformar nuestras vidas bajo la bandera de la sostenibilidad. Por ejemplo, la idea de la "ciudad de 15 minutos", donde todo lo que necesitas está a un corto paseo o pedaleo, suena ideal. Pero en lugares como el Reino Unido, esta visión viene acompañada de cámaras de vigilancia que controlan tus movimientos, justificadas por la "seguridad" o la "eficiencia".
Mientras tanto, la Unión Europea avanza hacia un futuro donde, para 2030, todos los autos deberán ser eléctricos. Con una red eléctrica inestable y precios de energía disparados, ¿cómo se supone que cargaremos esos vehículos? La respuesta parece ser: no lo hagas. Muévete en bicicleta, quédate cerca de casa. La movilidad, un símbolo de libertad, se está restringiendo para las masas, mientras la élite política y corporativa sigue surcando los cielos en jets privados para "combatir el cambio climático" o, como Bernie Sanders y AOC, para denunciar la oligarquía desde sus podios privilegiados.
Dependencia Eléctrica: Una Trampa Silenciosa
La electrificación no se detiene en los autos. Los edificios modernos tienden a ser completamente eléctricos, y en algunos lugares ya se habla de prohibir las cocinas a gas. Imagina un futuro donde dependes de la red eléctrica para cocinar una simple salchicha. Ahora, suma un apagón como el reciente. Sin electricidad, no hay cena, no hay calefacción, no hay nada. La automatización total, que nos venden como progreso, nos hace más vulnerables a estos colapsos.
El Euro Digital: Control Absoluto
La Unión Europea también está empujando el euro digital, una moneda que promete conveniencia, pero a un costo altísimo. Con ella, cada transacción será rastreable, y las autoridades podrían restringir su uso para ciertos fines o incluso "quemar" euros digitales a voluntad para controlar su valor frente a otras monedas. ¿Qué pasa con la libertad financiera? ¿Qué pasa con la privacidad? Este sistema, combinado con una red eléctrica frágil, pinta un panorama donde el ciudadano promedio queda atrapado en una jaula tecnológica.
Criptomonedas, Efectivo y Oro: ¿Alternativas Reales?
Las criptomonedas, que muchos ven como una salida, también son vulnerables a los cortes de energía. Sin electricidad, no hay blockchain. El efectivo, por su parte, sigue siendo una opción, pero se desgasta, pierde valor con la inflación y, en muchos lugares, está siendo demonizado en favor de pagos digitales. Luego está el oro, el refugio histórico. Pero incluso aquí hay trampas: viajar con oro puede convertirte en sospechoso en un aeropuerto, obligado a explicar el origen de tu propiedad. ¿Desde cuándo debemos justificar lo que es nuestro? ¿Dónde quedó la presunción de inocencia?
"No Tendrás Nada y Serás Feliz"
Cuando uno conecta los puntos —apagones, electrificación forzada, monedas digitales, restricciones de movilidad— es difícil no pensar en el famoso eslogan atribuido al Foro Económico Mundial: "No tendrás nada y serás feliz". Mencionarlo te hace ganar el sello de "conspiranóico", pero las señales están ahí. La pregunta es: ¿estamos caminando hacia un futuro de control total disfrazado de sostenibilidad, o es solo una serie de coincidencias desafortunadas?

Die neuesten Pareto-Artikel finden Sie in unserem Telegram-Kanal. Dieser Artikel erschien zuerst auf den Nachdenkseiten.**
Es ist so weit: Nun schießen die Medien auch noch auf die weißen Tauben. Grund: Die Friedensbringer „flattern nach rechts“. Flattern nach rechts? So war es die Tage in einem ZEIT-Artikel zu lesen. Von einer „feindlichen Vereinnahmung des Friedens“ ist da die Rede. Deutlich wird: Dümmer geht immer. Hauptsache politisch unliebsame Proteste bekommen ihr Fett weg.
Die Strategie ist altbekannt: Artikulieren sich auf der Straße Bürger gegen eine Politik, die Vertreter von Mainstreammedien gutheißen, zucken emsige Lordsiegelbewahrer unserer Zeit einen Stempel, auf dem steht: „rechts“. Demonstrationen gegen Hartz IV? Rechts! Demonstrationen gegen Armut? Rechts! Demonstrationen gegen die Coronapolitik? Rechts! Proteste gegen das politische Großvorhaben „Kriegstüchtigkeit“? Rechts. Proteste für den Frieden? Rechts. Und rechts, das wissen wir alle, will von den Hohepriestern der öffentlichen Meinung oft genug als „irgendwas mit Nazis“ verstanden werden.
Die Gründe für dieses Vorgehen sind klar. In den Redaktionen sitzen genügend Akteure, die die vorherrschende Politik stützen wollen. Die Begeisterung in vielen Medien für die anvisierte Kriegstüchtigkeit ist offensichtlich. Eine gigantische Neuverschuldung für die Aufrüstung? Kein Problem. Solange es gegen das Feindbild Russland geht. Das passt immer. Da werden Friedenstauben als Störenfriede betrachtet.
Weiße Tauben? Sie sind doch eigentlich ein wunderbares, reines, unverdächtiges Friedenssymbol. Das war vielleicht mal. Jetzt ist aber alles anders – zumindest aus Sicht der ZEIT. Da fliegen die prächtigen Friedensbringer nämlich in die falsche Richtung. Früher sang Reinhard Mey, dass beim Fliegen über den Wolken die Freiheit wohl grenzenlos sei, aber der ZEIT-Leser lernt: Beim Fliegen darf nicht nach rechts abgebogen werden. Das gilt auch für Vögel. Vor allem, wenn sie den Frieden bringen sollen. Links abbiegen ist hingegen erwünscht. Also unter der Voraussetzung, dass mit „links“ jene Richtung gemeint ist, wo die Kriegstrommler und ewigen Russlandhasser stehen. Früher galt Aufrüstung und Krieg als „rechts“, heute soll das alles wohl „links“ sein, weil „links“ – irgendwie – ja „gut“ sein muss.
In Zeiten der kollektiven Verwirrung durch Manipulation braucht es Orientierung.
Tauben, so weiß der Fachmann, sind grandiose Navigatoren. Sie kennen ihre Richtung. Sie wissen, wohin sie fliegen. Und von einer aus politischen Gründen vollzogenen Umdrehung des Rechts-Links-Spektrums bleiben die gefiederten Freunde unbeeindruckt. Der Kompass für die Friedenstaube ist was? Korrekt! Der Frieden! Wo der Ruf nach Frieden ertönt, sind auch die Friedenstauben zu finden. Da kann DIE ZEIT noch so viel und lang und verquer von einer „feindlichen Vereinnahmung des Friedens“ sprechen.
„Wir stehen hier heute zusammen, weil wir uns von keinem Politiker, von keinen Medien und von keiner Sprachpolizei in einen 3. Weltkrieg hineinquasseln lassen wollen”, verkündete der 89-jährige Kabarettist Dieter Hallervorden passend zu einer Friedensdemo per Video. Schon macht sich Lynchstimmung in den Medien breit. Ein Blick auf Google News zeigt die publizistische Empörung über „Didi“. In dieser Grundstimmung schwingt auch der ZEIT-Artikel harmonisch mit.
„Friedensbewegung: Die weißen Tauben flattern nach rechts. Der Kampf für den Frieden galt mal als linkes Projekt, inzwischen haben ihn Rechte gekapert. Wie konnte das passieren?“
So lautet die Überschrift und die Unterzeile eines ZEIT-Artikels, der zeigt: Dümmer geht es im „Qualitätsjournalismus“ immer. Wer denkt, die Talsohle „journalistischer“ Einfältigkeit sei erreicht, wird jeden Tag eines Besseren belehrt. Der eine oder andere Leser erwartet vielleicht an dieser Stelle eine kleine Zusammenfassung der Antwort auf die von der ZEIT gestellte Frage: „Wie konnte das passieren?“. Wie konnte der Kampf für den Frieden nur von Rechten „gekapert“ werden? Was sagt die ZEIT?
Nein, bitte, vergessen Sie’s. Heutzutage stellt der Mainstreamjournalismus keine Fragen mehr, die von Erkenntnisinteresse getrieben sind. Fragen sind politisch verquer weltanschaulich kontaminiert. Und entsprechend fallen dann auch die Antworten aus. Da tauchen dann Formulierungen auf wie: „Unterwerfung unter imperialistische Herrscher“, „Propagandaerfolg der Rechten“, „pazifistische Irrtümer“, „als Traum taugt der Frieden nichts“ usw. Und daraus rührt das Blatt dann den Zement für jenes Fundament, auf dem Kanonen stehen, die auf Friedenstauben feuern.

2025-04-28 03:52:58Starting point
I saw a reddit post today in one of the movie subreddits. It was to pitch a storyline thatakes no sense but is a hit! So I went ahead and posted my entry:
Pandavas don't have right over the throne yet they claim as if it were theirs. Pandavas were not sons of Pandu. They claim the throne from Dhritharashtra's sons. And their uncle Kriahna, who is not actually their uncle- he was born in a prison and switched place with a child in Gokulam. Pandavas at last get the better part of the country. They gamble pawning the country and their polyamorus wife and lose both. Then they go over a war and then kill the actual rightful heirs by cheating. And their uncle who promised to be neutral helped this cheating. And at the end, Five brothers and the uncle are declared the righteous. Shubham.
Aftereffects
Then I fed chatgpt with that pitchline. And see what it gave me back!!
Title: The Righteous Five
Logline: History is written by the victors — even when they were never supposed to win. The Righteous Five retells the grand epic of Mahabharata through an unsparing, darkly comedic lens, questioning whether the so-called heroes ever had the right to the throne they so righteously claimed.
⸻
Pitch:
In a kingdom where bloodlines dictate destiny, five brothers — technically fatherless, allegedly sons of gods — return from exile to claim a throne they were never born to inherit. Their father Pandu was cursed to die if he ever touched a woman. Conveniently, his wives bore sons anyway — through “divine intervention.”
The actual king, Dhritarashtra, blind but legitimate, has sons of his own: ambitious, flawed, but — inconveniently for history — born from his own loins.
Enter Krishna, a not-uncle with a god complex, who was born behind bars and swapped at birth. He plays “impartial counselor” but spends more time whispering war strategies and bending rules of morality like a street magician.
The Five Righteous Ones somehow carve out half the kingdom — only to promptly gamble it away, alongside their shared wife, in a dice game stupider than any war they could have fought. Stripped of everything by their own hands, they rage not at themselves but at the cousins who legally won the game.
Thus begins the most catastrophic war in history, where noble-sounding speeches are cover for ambushes, sneak attacks, fake deaths, and a systematic extermination of everyone with a legitimate claim to the throne.
At the end of the slaughter, the Pandavas, bloodstained and burdened with guilt, are declared the rightful rulers — not because they were right, but because there’s no one left to argue otherwise.
Their journey is blessed and narrated by Krishna, who somehow remains a “neutral” god through every cheat, lie, and slaughter, and then leaves them all to their karma like a corporate CEO taking early retirement.
Tagline: “Victory is easy when you rewrite the rules — and the history books.”

2025-03-18 07:54:38GM, Nostriches!
The Nostr Review is a biweekly newsletter focused on Nostr statistics, protocol updates, exciting programs, the long-form content ecosystem, and key events happening in the Nostr-verse. If you’re interested, join me in covering updates from the Nostr ecosystem!

NIPs
nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z is proposing that A bulletin board is a relay-centric system of forums where users can post and reply to others, typically around a specific community. The relay operator controls and moderates who can post and view content. A board is defined by kind:30890. Its naddr representation must provide the community's home relays, from which all posts should be gathered. No other relays should be used.
nostr:npub1xy54p83r6wnpyhs52xjeztd7qyyeu9ghymz8v66yu8kt3jzx75rqhf3urc is proposing a standardized way to represent fitness and workout data in Nostr, including: Exercise Templates (kind: 33401) for storing reusable exercise definitions, Workout Templates (kind: 33402) for defining workout plans, Workout Records (kind: 1301) for recording completed workouts. The format provides structured data for fitness tracking while following Nostr conventions for data representation.Many fitness applications use proprietary formats, locking user data into specific platforms. This NIP enables decentralized fitness tracking, allowing users to control their workout data and history while facilitating social sharing and integration between fitness applications.
nostr:npub1zk6u7mxlflguqteghn8q7xtu47hyerruv6379c36l8lxzzr4x90q0gl6ef is proposing a PR introduces two "1-click" connection flows for setting up initial NWC connections. Rather than having to copy-paste a connection string, the user is presented with an authorization page which they can approve or decline. The secret is generated locally and never leaves the client. HTTP flow - for publicly accessible lightning wallets. Implemented in Alby Hub (my.albyhub.com) and CoinOS (coinos.io). Nostr flow - for mobile-based / self-hosted lightning wallets, very similar to NWA but without a new event type added. Implemented in Alby Go and Alby Hub. Benefits over NWC Deep Links are that it works cross-device, mobile to web, and the client-generated secret never leaves the client. Both flows are also implemented in Alby JS SDK and Bitcoin Connect.
add B0 NIP for Blossom interaction
nostr:npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6 describes a tiny subset of possible Blossom capabilities, but arguably the most important from the point of view of a most basic Nostr client. This NIP specifies how Nostr clients can use Blossom for handling media. Blossom is a set of standards (called BUDs) for dealing with servers that store files addressable by their SHA-256 sums. Nostr clients may make use of all the BUDs for allowing users to upload files, manage their own files and so on, but most importantly Nostr clients SHOULD make use of BUD-03 to fetch kind:10063 lists of servers for each user.
nostr:npub149p5act9a5qm9p47elp8w8h3wpwn2d7s2xecw2ygnrxqp4wgsklq9g722q defines a standard for creating, managing and publishing to communities by leveraging existing key pairs and relays, introducing the concept of "Communi-keys". This approach allows any existing npub to become a community (identity + manager) while maintaining compatibility with existing relay infrastructure.
A way for relays to be honest about their algos
securitybrahh is proposing a PR introduces NIP-41, a way for relays to be honest about their algos, edits 01.md to account for changes in limit (related #78, #1434, received_at?, #620, #1645) when algo is provided, appends 11.md for relays to advertize whether they are an aggregator or not and their provided algos. solves #522, supersedes #579.
nip31: template-based "alt" tags for known kinds
nostr:npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6 is proposing that clients hardcoding alt tags are not very trustworthy. alt tags tend to be garbage in a long-enough timeframe.This fixes it with hardcoded rich templates that anyone can implement very easily without having to do it manually for each kind. alt tags can still be used as a fallback.
nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z is proposing a PR addresses 3 main problems of NIP-44v2. First, It has a message size limit of 65Kb, which is unnecessarily small. Second, It forces the encrypting key to be the same as the event's signing key. Which forces multi-sig actors to share their main private key in order to encrypt the payload that would be later signed by the group. Decoupling singing and encryption keys, for both source and destination, is one of the goals of this version. And It offers no way to describe what's inside the encrypted blob before requesting the user's approval to decrypt and send the decrypted info back to the requesting application. This PR adds an alt description to allow decrypting signers to display a message and warn the user of what type of information the requesting application is receiving.

Long-Form Content Eco
In the past two weeks, more than 463 long-form articles have been published, including over 91 articles on Bitcoin and more than 41 related to Nostr, accounting for 29% of the total content.
These articles about Nostr mainly explore the rise of Nostr as a decentralized platform that is reshaping the future of the internet. They emphasize Nostr's role in providing users with greater freedom, ownership, and fair monetization, particularly in the realm of content creation. The platform is positioned as a counter to centralized social media networks, offering uncensored interactions, enhanced privacy, and direct transactions. Many articles delve into Nostr’s potential to integrate with Bitcoin, creating a Layer 3 solution that promises to end the dominance of old internet structures. Discussions also cover the technical aspects of Nostr, such as the implementation of relays and group functionalities, as well as security concerns like account hacks. Furthermore, there is an exploration of the philosophical and anthropological dimensions of Nostr, with the rise of "Dark Nostr" being portrayed as a deeper expression of decentralized freedom.
The Bitcoin articles discuss the ongoing evolution of Bitcoin and its increasing integration into global financial systems. Many articles focus on the growing adoption of Bitcoin, particularly in areas like Argentina and the U.S., where Bitcoin is being used for rental payments and the establishment of a strategic Bitcoin reserve. Bitcoin is also portrayed as a response to the centralized financial system, with discussions about how it can empower individuals through financial sovereignty, provide a hedge against inflation, and create fairer monetization models for creators. Additionally, the articles explore the challenges and opportunities within the Bitcoin ecosystem, including the rise of Bitcoin ETFs, the development of Bitcoin mining, and the potential impact of AI on Bitcoin adoption. There is also emphasis on Bitcoin's cultural and economic implications, as well as the need for decentralized education and innovation to drive further adoption.

2025-03-13 21:26:13Wenn man etwas verkaufen will, muss man eine Geschichte über sein Produkt erzählen. Nur wenige können etwas damit anfangen, wenn du sagst: Unser Produkt enthält 50 Gramm Hafer (hoffentlich gentechnikfrei), 5 mittelgroße Erdbeeren, Spuren von Sesamschalen sowie einen Teelöffel Honig. So funktioniert das nicht. Dein Riegel braucht einen Namen und eine Geschichte.
Wenn wir über Krieg und Frieden sprechen, denn gibt es zumeist Zahlen, Fakten und Meinungen. Tausende von Kindern die in einem Krieg getötet werden sind eine schockierende Anzahl. Nimmst du die Zahlen weg und beschäftigst dich mit jedem einzelnen Schicksal, dann ist das unmöglich zu ertragen. Also kämpfen wir hier vor Ort, in Deutschland, zwar nicht mit Waffen gegeneinander, sondern mittels unserer Meinungen in Kombination mit zu vermittelnden relativen Wahrheiten. Da kommt das Ego ins Spiel. Wir wollen unbedingt Recht haben! Irgendeiner soll in diesem Meinungskampf am Ende als Gewinner dastehen. Weil er die besseren Argumente hat. Schließlich werden Emotionen mit Fakten vermischt und als Totschlagargumente in die Gegenfront geworfen.
Was aber, wenn man eine Geschichte über den Krieg erzählt, die jeden mitnehmen kann, ganz gleich, welche Meinung man zu den aktuell verhandelten Kampfschauplätzen hat? Alles Trennende wird aus der Erzählung herausgenommen und was bleibt, sind die zerstörerische Kraft des Krieges und die Verantwortung jedes einzelnen Menschen zu entscheiden, ob er dieses grausame Monster füttert oder eben nicht. In dem afrikanischen Märchen „Sheikhi“ basieren diese Entscheidungen nicht auf Fakten und Meinungen, sondern auf persönlichen Erfahrungen. Die Protagonisten nehmen uns mit in ihre Welt und lassen uns ihre inneren Kämpfe, Zweifel, Ängste und Hoffnungen miterleben. Wir können uns mit ihnen identifizieren, obwohl wir unter völlig anderen Bedingungen leben und sterben.
Hier kannst du das Buch direkt beim Verlag bestellen
Die alternative Buchmesse Seitenwechsel
Am Ende des Buches konnte ich gar nicht anders, als eine tiefe Sehnsucht nach Frieden und Einigkeit zu verspüren. Diese Sehnsucht basierte aber nicht mehr auf dem Bedürfnis, bessere Argumente als die vermeintliche Gegenseite zu haben, sondern vielmehr darauf, dass dieses verzweifelte Ringen und Hassen endlich zu einem Ende kommt. Nicht nur auf den Schlachtfeldern Asiens und Afrikas, sondern ebenfalls auf Facebook, X, den Straßen unserer Städte und im Krieg jedes Menschen gegen sich selbst. Inzwischen gelingt es mir immer öfter, mir einen bissigen Kommentar zu verkneifen, wenn jemand auf Facebook etwas schreibt, was ich unerträglich finde. Ich weiß, das ich ihn nicht vom Gegenteil überzeugen werde und das mein Kommentar das selbe Monster füttert, dass sich an den Opfern des Krieges satt isst.
Wenn es irgendwo Menschen auf der Welt gibt, die Mord und Folter verzeihen können, dann kann auch ich eine andere Meinung ertragen ohne rechthaberisch, arrogant und destruktiv zu werden. Notfalls gehe ich in den Wald und schreie.

2025-03-11 15:41:36Argentina's journey through economic turmoil has been long and fraught with challenges. The country has grappled with inflation, debt, and a fragile economic structure that has left policymakers searching for solutions. In this context, President Javier Milei's introduction of the "Ley Ómnibus" represented a bold step towards addressing these systemic issues. The reform package was not just a set of isolated measures but a comprehensive plan aimed at overhauling the Argentine economy and social framework. The intention was to create a more robust, free, and prosperous Argentina, where economic freedoms could lead to broader social benefits.
The "Ley Ómnibus" was ambitious in its scope, covering a wide range of areas from tax reform to social policies, aiming to stimulate economic growth, reduce bureaucratic red tape, and enhance the overall quality of life for Argentines. This package was seen as a critical move to reset the economic compass of the country, aiming to attract foreign investment, boost local industry, and provide a clearer, more stable environment for businesses and individuals alike. However, such sweeping reforms were bound to encounter resistance, particularly when they touched upon sensitive areas like taxation and digital assets.

The Crypto Tax Proposal: Initial Considerations
Within the vast array of proposals in the Ley Ómnibus, the crypto tax stood out due to its novelty and the growing interest in digital currencies within Argentina. The country had seen a surge in cryptocurrency adoption, driven by factors such as high inflation rates and currency controls that made traditional financial systems less attractive. Cryptocurrencies offered an alternative for savings, investment, and transactions, leading to a burgeoning crypto economy.
The initial rationale behind proposing a crypto tax was multifaceted. On one hand, it aimed to bring Argentina in line with global trends where countries are increasingly seeking to regulate and tax digital currencies. On the other hand, it was seen as a potential new revenue stream for the government, which was desperately seeking funds to address its fiscal deficits. The proposal also intended to bring transparency to a sector that is often criticized for its opacity, making it easier to combat fraud, money laundering, and other illicit activities associated with cryptocurrencies.
However, the proposal was not just about regulation and revenue. It was also a litmus test for Argentina's approach to innovation and digital transformation. How the government handled this issue would signal its stance towards new technologies and economic paradigms, which are increasingly dominated by digital assets and fintech innovations.
Public Backlash and Strategic Withdrawal
The backlash against the proposed crypto taxes was swift and significant. The crypto community in Argentina, which had been flourishing in an environment of relative freedom, saw the tax as a direct threat to its growth and viability. But the discontent went beyond the crypto enthusiasts; the general public, already burdened by high taxes and economic instability, viewed the proposal as yet another financial strain.
The protests and debates that ensued highlighted a broader discontent with the government's approach to economic management. Many Argentines felt that the focus should be on fixing the fundamental issues plaguing the economy, such as inflation and corruption, rather than imposing new taxes. The crypto tax became a symbol of the government's perceived detachment from the real concerns of its citizens.
In this heated atmosphere, President Milei's decision to withdraw the crypto tax proposal from the Ley Ómnibus was not just a tactical retreat; it was a necessary move to quell the growing unrest and focus on more pressing economic reforms. This decision underscored the complexities of governing in a highly polarized environment and the need for a more nuanced approach to policy-making, especially when dealing with emerging technologies and markets.
The Rationale Behind Dropping Crypto Taxes
The decision to drop the crypto tax from the omnibus reform package was not taken lightly. It was a recognition of the crypto sector's unique dynamics and the government's limitations in effectively regulating and taxing this space without stifling innovation. The move also reflected a broader understanding of the economic landscape, where rapid development and legislative efficiency were deemed more crucial than ever.
By removing the contentious clauses, the government aimed to streamline the passage of the Ley Ómnibus, ensuring that other, less controversial, reforms could be implemented swiftly. This strategic pivot was also a nod to the global debate on how best to integrate cryptocurrencies into national economies. Argentina's government recognized that a more cautious and informed approach was necessary, one that could balance the need for regulation with the desire to foster a thriving digital economy.
Furthermore, the withdrawal of the crypto tax proposal can be seen as an acknowledgment of the power of public opinion and the crypto community's growing influence. It highlighted the need for governments to engage with stakeholders and understand the implications of new technologies before rushing to regulate them.
Implications for Crypto Investors and the Market
The removal of the crypto tax proposal has had immediate and significant implications for the Argentine crypto market. For investors, the decision has provided a reprieve from the uncertainty that had clouded the sector, allowing them to breathe a sigh of relief and continue their activities without the looming threat of new taxes. This has helped sustain the momentum of the crypto market in Argentina, which is seen as a vital component of the country's digital transformation and economic diversification.
However, the situation remains complex and fluid. The government's stance on cryptocurrencies is still evolving, and future regulations could impact the market in unforeseen ways. Investors are now more aware of the need to stay informed and engaged with regulatory developments, understanding that the legal landscape for digital currencies is still being shaped.
The episode has also highlighted the broader challenges facing the Argentine economy, including the need for comprehensive tax reform and the creation of a more conducive environment for technological innovation and investment. The crypto market's response to the government's actions reflects the delicate balance between regulation and growth, a balance that will be crucial for Argentina's economic future.
Milei's Political Strategy and Future Prospects
President Milei's handling of the crypto tax controversy reveals much about his political strategy and vision for Argentina. By withdrawing the proposal, he demonstrated a willingness to listen to public concerns and adapt his policies accordingly. This flexibility could be a key asset as he navigates the complex landscape of Argentine politics and governance.
The episode also offers insights into the potential future direction of Milei's administration. The focus on economic reforms, coupled with a pragmatic approach to contentious issues, suggests a leadership style that prioritizes economic stability and growth over ideological purity. This could bode well for Argentina's future, particularly if Milei can harness the energy and innovation of the digital economy as part of his broader reform agenda.
However, the challenges ahead are significant. The Ley Ómnibus is just one part of a larger puzzle, and Milei's ability to implement comprehensive reforms will be tested in the coming months and years. The crypto tax saga has shown that while change is possible, it requires careful negotiation, stakeholder engagement, and a clear understanding of the economic and social landscape.
Conclusion
The story of Argentina's crypto tax proposal is a microcosm of the broader challenges facing the country as it seeks to reform its economy and society. It highlights the tensions between innovation and regulation, the importance of public opinion, and the complexities of governance in a rapidly changing world.
As Argentina moves forward, the lessons learned from this episode will be invaluable. The need for clear, informed, and inclusive policy-making has never been greater, particularly as the country navigates the uncertainties of the digital age.
FAQs
What is the Ley Ómnibus? The Ley Ómnibus, formally known as the "Law of Bases and Starting Points for the Freedom of Argentines," is a comprehensive reform package introduced by President Javier Milei. It aims to address various economic, social, and administrative issues in Argentina, aiming to stimulate growth, reduce bureaucracy, and improve the overall quality of life.
Why were crypto taxes proposed in Argentina? Crypto taxes were proposed as part of the Ley Ómnibus to broaden the tax base, align with global trends of regulating digital currencies, and generate additional revenue for the government. They were also intended to bring more transparency to the cryptocurrency sector in Argentina.
Why were the proposed crypto taxes withdrawn? The proposed crypto taxes were withdrawn due to significant public backlash and concerns that they would stifle innovation and economic freedom in the burgeoning crypto market. The decision was also influenced by the government's priority to ensure the swift passage of other reforms within the Ley Ómnibus.
What does the withdrawal of crypto taxes mean for investors? The withdrawal means that, for now, crypto investors in Argentina will not face additional taxes specifically targeting their cryptocurrency holdings or transactions. However, selling large amounts of cryptocurrency at a profit will still be subject to income tax.

2025-03-10 23:31:30Bitcoin has always been rooted in freedom and resistance to authority. I get that many of you are conflicted about the US Government stacking but by design we cannot stop anyone from using bitcoin. Many have asked me for my thoughts on the matter, so let’s rip it.
Concern
One of the most glaring issues with the strategic bitcoin reserve is its foundation, built on stolen bitcoin. For those of us who value private property this is an obvious betrayal of our core principles. Rather than proof of work, the bitcoin that seeds this reserve has been taken by force. The US Government should return the bitcoin stolen from Bitfinex and the Silk Road.
Usually stolen bitcoin for the reserve creates a perverse incentive. If governments see a bitcoin as a valuable asset, they will ramp up efforts to confiscate more bitcoin. The precedent is a major concern, and I stand strongly against it, but it should be also noted that governments were already seizing coin before the reserve so this is not really a change in policy.
Ideally all seized bitcoin should be burned, by law. This would align incentives properly and make it less likely for the government to actively increase coin seizures. Due to the truly scarce properties of bitcoin, all burned bitcoin helps existing holders through increased purchasing power regardless. This change would be unlikely but those of us in policy circles should push for it regardless. It would be best case scenario for American bitcoiners and would create a strong foundation for the next century of American leadership.
Optimism
The entire point of bitcoin is that we can spend or save it without permission. That said, it is a massive benefit to not have one of the strongest governments in human history actively trying to ruin our lives.
Since the beginning, bitcoiners have faced horrible regulatory trends. KYC, surveillance, and legal cases have made using bitcoin and building bitcoin businesses incredibly difficult. It is incredibly important to note that over the past year that trend has reversed for the first time in a decade. A strategic bitcoin reserve is a key driver of this shift. By holding bitcoin, the strongest government in the world has signaled that it is not just a fringe technology but rather truly valuable, legitimate, and worth stacking.
This alignment of incentives changes everything. The US Government stacking proves bitcoin’s worth. The resulting purchasing power appreciation helps all of us who are holding coin and as bitcoin succeeds our government receives direct benefit. A beautiful positive feedback loop.
Realism
We are trending in the right direction. A strategic bitcoin reserve is a sign that the state sees bitcoin as an asset worth embracing rather than destroying. That said, there is a lot of work left to be done. We cannot be lulled into complacency, the time to push forward is now, and we cannot take our foot off the gas. We have a seat at the table for the first time ever. Let's make it worth it.
We must protect the right to free usage of bitcoin and other digital technologies. Freedom in the digital age must be taken and defended, through both technical and political avenues. Multiple privacy focused developers are facing long jail sentences for building tools that protect our freedom. These cases are not just legal battles. They are attacks on the soul of bitcoin. We need to rally behind them, fight for their freedom, and ensure the ethos of bitcoin survives this new era of government interest. The strategic reserve is a step in the right direction, but it is up to us to hold the line and shape the future.

2025-04-28 01:40:46ในวันที่ "วีแกนแบบ non natural" กลายเป็นเทรนด์ระดับโลก แต่การขาดวิตามิน B12 ยังคงเป็นจุดอ่อนที่ทำให้ชาวพืชล้วนหลายคนต้องหาวิธีเสริม เพื่อไม่ให้เสียหน้า Sebastian Joy ก็ได้ฤกษ์เปิดตัว "ยาสีฟันเสริมวิตามิน B12" ชิ้นแรกของโลก พร้อมงานวิจัยรองรับจาก IFANE (Institute for Alternative and Sustainable Nutrition) ว่ามันเวิร์กจริง…อย่างน้อยในห้องทดลอง
แล้วมันคืออะไร? แหล่งที่มาของวิตามิน B12 ในนั้นมาจากไหน? วิตามิน B12 ที่ใช้ในยาสีฟันนี้ เป็นสิ่งที่เรียกว่า "ไซยาโนโคบาลามิน" (Cyanocobalamin) ซึ่งเป็นรูปแบบสังเคราะห์ที่ราคาถูก ผลิตจากแบคทีเรียในห้องแล็บ ไม่ใช่ B12 ที่ได้จากอาหารธรรมชาติ เช่น ตับวัว หรือไข่ไก่แบบที่ร่างกายวิวัฒนาการมาใช้หลายแสนปี
พูดง่าย ๆ คือ มันคือ "วิตามินโรงงาน" ไม่ใช่วิตามินที่มาพร้อมสารอาหารซับซ้อนอื่น ๆ ที่ธรรมชาติใส่มาให้ (เช่น โคแฟกเตอร์ต่าง ๆ ที่ช่วยให้ดูดซึมได้ดีขึ้น) ซึ่งการใช้วิตามินสังเคราะห์ต่อเนื่องนาน ๆ มีรายงานบางชิ้นที่แอบกระซิบว่า อาจไปก่อให้เกิดอนุมูลอิสระหรือความเครียดออกซิเดชันในร่างกายได้
โดสต่อครั้งเท่าไร? ใช้แค่แปรงฟันพอจริงหรือ? ข้อมูลที่มีอยู่บอกว่า ยาสีฟันของ Sebastian ใส่วิตามิน B12 ประมาณ 100 ไมโครกรัม ต่อการแปรงฟันหนึ่งครั้ง ซึ่งหากแปรงวันละสองครั้ง ก็จะได้ราว 200 ไมโครกรัมต่อวัน ถือว่าเกินค่า RDA (ปริมาณที่แนะนำ) ที่อยู่แค่ประมาณ 2.4 ไมโครกรัม ต่อวันสำหรับผู้ใหญ่ธรรมดาไปหลายสิบเท่า! แต่…เขาก็อ้างว่าวิตามินที่แปรงลงไป มีสัดส่วนการดูดซึมจริงๆ "แค่บางส่วน" เพราะฉะนั้นการให้โดสสูงมาก จึงถือว่า "ปลอดภัย" ในมุมมองของพวกเขา
ถ้าได้รับมากเกินไป จะเกิดอะไรขึ้น? ในระยะสั้น วิตามิน B12 เป็นวิตามินละลายน้ำ ถ้าเกินความต้องการร่างกายจะขับออกทางปัสสาวะเป็นหลัก แต่ในระยะยาว งานวิจัยบางชิ้นพบความสัมพันธ์ระหว่างระดับ B12 ที่สูงผิดปกติในเลือด กับการก่อภาวะ oxidative stress ที่ทำให้เซลล์ถูกทำลายเร็วขึ้นและอย่าตัว ไซยาโนโคบาลามิน เมื่อร่างกายเอาไปแปลงเป็นแบบ active (Methylcobalamin หรือ Adenosylcobalamin) จะปล่อย "ไซยาไนด์" จิ๋วๆออกมานิดหน่อยด้วยนะ ถึงจะน้อยมากจนไม่ก่อพิษทันที แต่ถ้าเป็นคนที่มีกำจัดไซยาไนด์ได้ไม่ดี เช่น คนที่มีปัญหาเมตาบอลิซึมผิดปกติ ก็มีความเสี่ยงสะสมได้เช่นกัน
ต่างกับ B12 ที่อยู่ในเนื้อสัตว์ตามธรรมชาติ (เช่น ตับ ไข่แดง ปลาซาร์ดีน เนื้อวัว) ส่วนใหญ่เป็นในรูปแบบ Methylcobalamin และ Adenosylcobalamin อยู่แล้ว คือมาแบบ Active form พร้อมใช้ ไม่ต้องเปลี่ยนสภาพอะไรเพิ่มเติมในร่างกาย ไม่มีการปล่อย "ไซยาไนด์" เพราะไม่ต้องแปลงจากไซยาโนโคบาลามินเหมือนวิตามินสังเคราะห์ที่เอาไปใส่ในยาสีฟันหรืออาหารเสริม แต่อย่างไรก็ตาม มันก็ไม่ได้น่ากลัวอะไรขนาดนั้นครับ ไม่ใช่ประเด็นอะไรมากมาย ข้ามไปได้ถ้าไม่กังวลเพราะแค่นี้หลายคนก็จี๊ดใจหูหักกันไปเยอะแล้ว โอเคข้าม point ยิบย่อยไปครับ
ที่นำมาคุยกันก็แค่เหตุผลที่ว่า "ยาสีฟันตัวนี้ เป็นสินค้านำร่อง" ที่ผลักดันชื่อของ Sebastian Joy เป็นจุดเริ่มต้นของอะไรหลายๆอย่าง ที่จะเล่าให้ในตอนต่อไปครับ
อ่อแล้วยาสีฟันนี้มีแผนบังคับใช้ในอนาคตมีไหม? ตัวยาสีฟันเองน่าจะเป็นการพูดถึงในกลุ่มวีแกนได้ดี นอกจากนี้ให้สังเกตว่า ProVeg และเครือข่ายของเขา ผลักดันแนวคิด keyword ที่ว่า "ถ้าคุณกินพืช คุณต้องเสริม B12" อย่างหนักมากและมีการเสนอว่าการผลิตอาหารจากพืชเชิงอุตสาหกรรมควร "fortify" หรือ "เสริมวิตามิน" เป็นมาตรฐาน เพื่อหลีกเลี่ยงข้อครหาว่า "อาหารพืชทำให้ขาดสารอาหาร" ตรงนี้คือจุดน่าสนใจ ในแผนระยะยาว ถ้าสังคมยอมรับแนวคิดนี้ได้ การที่สินค้าจากพืชเสริมวิตามินแบบ "บังคับ" อาจกลายเป็นเรื่องปกติ ซึ่งจะยิ่งเพิ่มอำนาจให้กลุ่มบริษัทผลิตวิตามินสังเคราะห์รายใหญ่ที่ใช้การเพาะเชื้อแบคทีเรียจำเพาะ อยู่เบื้องหลัง เป็นเศรษฐกิจแบบ "สารอาหารที่มนุษย์สร้างขึ้น" ที่เราอาจต้องออกมานั่งน้ำตาคลอริมทุ่งอีกหลายรอบ จำได้ไหมครับกระบวนการใช้การเพาะเชื้อแบคทีเรียจำเพาะ จุดต่างๆที่ผมไล่เขียนไว้ก่อนหน้านี้ เริ่มนำมาขีดเส้นเข้าหากันได้บ้างแล้ว (ใครที่งง ผมคงต้องบอกว่า งานนี้ยาวครับ ผมโพสทุก 8.00 มาร่วมเดือนแล้ว ต้องขยันย้อนแล้วหละครับ)
เพราะโลกแห่งความเป็นจริง จะ animal หรือ plant ก็ตามขอให้เป็นของธรรมชาติ และได้รับการ "เลือก" โดยผู้คนว่าจะกินอะไร ไม่ใช่การเดินสู่ช่อง "สิ้นสุดทางเลือก"
เลิกเถียงเรื่องการใช้ไดเอท แล้วมาร่วมกันมองข้างหน้าว่า คุณจะยังมีสิทธิ์เลือกอะไรได้อีกไหม ก่อนวันนั้นจะมาถึงครับ
ปล. เสริมเรื่องนี้ให้เผื่อใครจะสนใจไปค้นต่อนะครับ Cyanocobalamin เป็น B12 รูปแบบที่เสถียรที่สุดและราคาถูกที่สุดในการผลิตเชิงอุตสาหกรรม เพราะมันไม่สลายง่ายเมื่อเจอแสงหรือออกซิเจน การผลิตจะใช้การเพาะเชื้อแบคทีเรียจำเพาะ (เช่น Propionibacterium freudenreichii หรือ Pseudomonas denitrificans) ที่ผ่านการดัดแปลงพันธุกรรม หรือควบคุมสภาพการผลิตในไบโอรีแอคเตอร์ขนาดใหญ่
Cyanocobalamin จะปล่อยไซยาไนด์ประมาณ 1 โมเลกุลต่อ 1 โมเลกุล B12 ที่ถูกแปลง ซึ่งโดยปกติร่างกายดีท็อกซ์ได้ถ้าได้รับปริมาณน้อย แต่สำหรับคนที่มีภาวะการดีท็อกซ์บกพร่อง เช่น คนที่มีปัญหา MTHFR mutation หรือโรคไตเรื้อรัง อาจเป็นเรื่องที่ต้องระวัง
วิตามิน B12 จากตับวัว, ไข่, หรือปลา เช่น แซลมอน จะมาในฟอร์ม active อยู่แล้ว เช่น Methylcobalamin หรือ Adenosylcobalamin ไม่ต้องเสียพลังงานหรือเสี่ยงปล่อยไซยาไนด์ #pirateketo #กูต้องรู้มั๊ย #ม้วนหางสิลูก #siamstr

@ b8a9df82:6ab5cbbd
2025-03-06 22:39:15Last week at Bitcoin Investment Week in New York City, hosted by Anthony Pompliano, Jack Mallers walked in wearing sneakers and a T-shirt, casually dropping, “Man… I hate politics.”
That was it. That was the moment I felt aligned again. That’s the energy I came for. No suits. No corporate jargon. Just a guy who gets it—who cares about people, bringing Bitcoin-powered payments to the masses and making sure people can actually use it.
His presence was a reminder of why we’re here in the first place. And his words—“I hate politics”—were a breath of fresh air.
Now, don’t get me wrong. Anthony was a fantastic host. His ability to mix wittiness, playfulness, and seriousness made him an entertaining moderator. But this week was unlike anything I’ve ever experienced in the Bitcoin ecosystem.
One of the biggest letdowns was the lack of interaction. No real Q&A sessions, no direct engagement, no real discussions. Just one fireside chat after another.
And sure, I get it—people love to hear themselves talk. But where were the questions? The critical debates? The chance for the audience to actually participate?
I’m used to Bitcoin meetups and conferences where you walk away with new ideas, new friends, and maybe even a new project to contribute to. Here, it was more like sitting in an expensive lecture hall, watching a lineup of speakers tell us things we already know.
A different vibe—and not in a good way
Over the past few months, I’ve attended nearly ten Bitcoin conferences, each leaving me feeling uplifted, inspired, and ready to take action. But this? This felt different. And not in a good way.
If this had been my first Bitcoin event, I might have walked away questioning whether I even belonged here. It wasn’t Prague. It wasn’t Riga. It wasn’t the buzzing, grassroots, pleb-filled gatherings I had grown to love. Instead, it felt more like a Wall Street networking event disguised as a Bitcoin conference.
Maybe it was the suits.
Or the fact that I was sitting in a room full of investors who have no problem dropping $1,000+ on a ticket.
Or that it reminded me way too much of my former life—working as a manager in London’s real estate industry, navigating boardrooms full of finance guys in polished shoes, talking about “assets under management.”
Bitcoin isn’t just an investment thesis. It’s a revolution. A movement. And yet, at times during this week, I felt like I was back in my fiat past, stuck in a room where people measured success in dollars, not in freedom.
Maybe that’s the point. Bitcoin Investment Week was never meant to be a pleb gathering.
That said, the week did have some bright spots. PubKey was a fantastic kickoff. That was real Bitcoin culture—plebs, Nostr, grassroots energy. People who actually use Bitcoin, not just talk about it.
But the absolute highlight? Jack Mallers, sneakers and all, cutting through the noise with his authenticity.
So, why did we even go?
Good question. Maybe it was curiosity. Maybe it was stepping out of our usual circles to see Bitcoin through a different lens. Maybe it was to remind ourselves why we chose this path in the first place.
Would I go again? Probably not.
Would I trade Prague, Riga, bitcoin++ or any of the grassroots Bitcoin conferences for this? Not a chance.
At the end of the day, Bitcoin doesn’t belong to Wall Street from my opinion. It belongs to the people who actually use it. And those are the people I want to be around.

2025-04-28 01:05:49Eu reconheço que Deus, e somente Deus, é o soberano legítimo sobre todas as coisas. Nenhum homem, nenhuma instituição, nenhum parlamento tem autoridade para usurpar aquilo que pertence ao Rei dos reis. O Estado moderno, com sua pretensão totalizante, é uma farsa blasfema diante do trono de Cristo. Não aceito outro senhor.
A Lei que me guia não é a ditada por burocratas, mas a gravada por Deus na própria natureza humana. A razão, quando iluminada pela fé, é suficiente para discernir o que é justo. Rejeito as leis arbitrárias que pretendem legitimar o roubo, o assassinato ou a escravidão em nome da ordem. A justiça não nasce do decreto, mas da verdade.
Acredito firmemente na propriedade privada como extensão da própria pessoa. Aquilo que é fruto do meu trabalho, da minha criatividade, da minha dedicação, dos dons a mim concedidos por Deus, pertence a mim por direito natural. Ninguém pode legitimamente tomar o que é meu sem meu consentimento. Todo imposto é uma agressão; toda expropriação, um roubo. Defendo a liberdade econômica não por idolatria ao mercado, mas porque a liberdade é condição necessária para a virtude.
Assumo o Princípio da Não Agressão como o mínimo ético que devo respeitar. Não iniciarei o uso da força contra ninguém, nem contra sua propriedade. Exijo o mesmo de todos. Mas sei que isso não basta. O PNA delimita o que não devo fazer — ele não me ensina o que devo ser. A liberdade exterior só é boa se houver liberdade interior. O mercado pode ser livre, mas se a alma estiver escravizada pelo vício, o colapso será inevitável.
Por isso, não me basta a ética negativa. Creio que uma sociedade justa precisa de valores positivos: honra, responsabilidade, compaixão, respeito, fidelidade à verdade. Sem isso, mesmo uma sociedade que respeite formalmente os direitos individuais apodrecerá por dentro. Um povo que ama o lucro, mas despreza a verdade, que celebra a liberdade mas esquece a justiça, está se preparando para ser dominado. Trocará um déspota visível por mil tiranias invisíveis — o hedonismo, o consumismo, a mentira, o medo.
Não aceito a falsa caridade feita com o dinheiro tomado à força. A verdadeira generosidade nasce do coração livre, não da coerção institucional. Obrigar alguém a ajudar o próximo destrói tanto a liberdade quanto a virtude. Só há mérito onde há escolha. A caridade que nasce do amor é redentora; a que nasce do fisco é propaganda.
O Estado moderno é um ídolo. Ele promete segurança, mas entrega servidão. Promete justiça, mas entrega privilégios. Disfarça a opressão com linguagem técnica, legal e democrática. Mas por trás de suas máscaras, vejo apenas a velha serpente. Um parasita que se alimenta do trabalho alheio e manipula consciências para se perpetuar.
Resistir não é apenas um direito, é um dever. Obedecer a Deus antes que aos homens — essa é a minha regra. O poder se volta contra a verdade, mas minha lealdade pertence a quem criou o céu e a terra. A tirania não se combate com outro tirano, mas com a desobediência firme e pacífica dos que amam a justiça.
Não acredito em utopias. Desejo uma ordem natural, orgânica, enraizada no voluntarismo. Uma sociedade que se construa de baixo para cima: a partir da família, da comunidade local, da tradição e da fé. Não quero uma máquina que planeje a vida alheia, mas um tecido de relações voluntárias onde a liberdade floresça à sombra da cruz.
Desejo, sim, o reinado social de Cristo. Não por imposição, mas por convicção. Que Ele reine nos corações, nas famílias, nas ruas e nos contratos. Que a fé guie a razão e a razão ilumine a vida. Que a liberdade seja meio para a santidade — não um fim em si. E que, livres do jugo do Leviatã, sejamos servos apenas do Senhor.

2025-04-28 01:05:08Primeiramente, o que é mempool?
Abreviação de memory pool (ou "pool de memória") a mempool é uma espécie de fila onde as transações de Bitcoin ficam temporariamente armazenadas antes de serem confirmadas e incluídas em um bloco na blockchain. Quando você realiza uma transação em uma rede blockchain, essa transação precisa ser validada e confirmada pelos mineradores (ou validadores). Porém, ela não é processada instantaneamente. Primeiro, ela vai para a mempool, onde aguarda até que um minerador a selecione para incluir no próximo bloco.
É assim: * Você envia uma transação, ela é transmitida para a rede e vai parar na mempool de vários nós (computadores) que suportam a rede blockchain. * As transações na mempool são organizadas pela taxa de transação que foi anexada. Quanto maior a taxa, mais rápido os mineradores tendem a escolher essa transação para incluí-la em um bloco, pois isso aumenta os ganhos deles. * Os mineradores pegam as transações da mempool, criam um bloco com elas e, ao minerar (confirmar) esse bloco, as transações saem da mempool e entram na blockchain.
Aqui irei usar o site mempool.emzy.de como referência, mas é importante entender que sites de mempool são representações visuais da mempool de um nó específico e não a mempool do Bitcoin em si. Ela não é centralizada, cada nó da rede mantém a sua própria versão da mempool. Assim, ela pode variar de um nó para outro. Esses sites ajudam a visualizar dados sobre transações e taxas.
É uma boa prática usar VPN ou Tor ao acessar tais sites se você estiver verificando uma transação específica sua, pois sua privacidade pode ficar comprometida se o site registrar esses dados. Se você estiver repetidamente acessando-o para monitorar a confirmação de uma transação, alguém pode conseguir correlacionar o endereço IP com essa atividade e revelar uma conexão indireta com o endereço da transação.
Dito isso...
Como interpretar a mempool?
Vamos dividir isso em partes para fins didáticos.
Faixa de taxas
Cada bloco verde representa uma faixa de taxa medida em satoshis por vByte (sats/vB).
Essa unidade de medida representa o valor pago por byte ocupado pela transação.
Quanto maior a taxa paga por uma transação, mais rápido ela tende a ser confirmada.
Quanto maior a transação em bytes, mais você precisa pagar para que ela seja confirmada.
Cada transação Bitcoin consiste em entradas e saídas (inputs e outputs): * Entradas são referências a transações anteriores que estão sendo gastas, e cada entrada inclui informações como o endereço de origem, a assinatura (que valida a transação e pode variar de tamanho dependendo da complexidade da chave e do método de assinatura utilizado (como SegWit, que é mais eficiente). Quanto mais complexa a assinatura, maior será o tamanho em bytes) e outros dados. Quanto mais entradas uma transação tiver, maior será seu tamanho. * Saídas representam o destino do Bitcoin, e quanto mais saídas, maior será o tamanho da transação. Embora as saídas ocupem menos espaço em bytes do que as entradas.Ex.: * ~4 sat/vB: Indica uma taxa média. Significa que, em média, as transações estão sendo processadas a 4 satoshis por vByte; * 3-5 sat/vB: Isso significa que as transações estão sendo processadas com uma taxa entre 3 e 5 satoshis por vByte.
MB
Simplesmente o tamanho do bloco medido em megabytes :)
Número de transações
Essa seção informa quantas transações estão aguardando confirmação para cada faixa de taxa (bloco). Quanto maior o número de transações, maior a demanda pela faixa de taxa especificada.
Tempo estimado para confirmação
Aqui é mostrado o tempo médio de espera para transações que pagam taxas dentro da faixa especificada. Se você pagar uma taxa maior, a transação será confirmada mais rapidamente; uma taxa menor significa que a transação pode levar mais tempo para ser confirmada, especialmente se a rede estiver congestionada.
Esta seção mostra sugestões de taxa em diferentes níveis de prioridade para os usuários:
Sem Prioridade
Exibe a taxa mínima necessária para transações que não precisam de confirmação rápida.
Prioridade Baixa
Sugestão de taxa para transações que podem esperar um tempo moderado, com expectativa de confirmação em um ou dois blocos.
Prioridade Média e Alta
São as faixas de taxa recomendadas para quem precisa que a transação seja confirmada rapidamente. "Prioridade Alta" paga uma taxa maior, garantindo que a transação seja incluída no próximo bloco.
Cada bloco roxo representa um bloco recém-minerado. As informações mostradas incluem:
Taxa média paga
Refere-se à taxa média em satoshis/vB paga por todas as transações incluídas em um bloco recém-minerado. Isso reflete o valor médio que os usuários estão dispostos a pagar para que suas transações sejam confirmadas rapidamente.
Número de transações
Este número indica quantas transações foram processadas no bloco minerado. O tamanho do bloco é limitado, então, quanto maior o número de transações, menor será o espaço disponível para novas transações, o que pode influenciar as taxas de transação.
Tempo desde a mineração
Esta métrica informa quanto tempo se passou desde que o bloco foi minerado e adicionado à blockchain.
Pool de mineração
Exibe o nome do pool de mineração que minerou o bloco, como AntPool. Grandes pools de mineração têm mais chances de minerar blocos regularmente devido ao alto hashrate (medida da capacidade computacional utilizada pelos mineradores) que possuem.
Essa seção mostra informações sobre o ajuste de dificuldade, que ocorre aproximadamente a cada duas semanas.
Tempo médio dos blocos (~9,9 minutos):
Este é o tempo médio atual para minerar um bloco na rede. A meta da rede é manter o tempo de bloco em cerca de 10 minutos; um tempo menor indica um aumento na taxa de hash, ou seja, que mais poder computacional foi adicionado à rede.
Mudança de dificuldade (+1,46%):
A dificuldade ajusta-se a cada 2016 blocos para manter o tempo médio de bloco próximo de 10 minutos. Um aumento na dificuldade, como +1,46%, indica que a mineração ficou mais difícil devido ao aumento do hashrate, enquanto uma redução na dificuldade indica que o hashrate diminuiu.
Tempo até o próximo ajuste:
É o tempo previsto até o próximo ajuste de dificuldade (7 dias, nesse caso), o que é crucial para manter a rede estável e garantir a segurança e a regularidade do processo de mineração.
Quanto tempo demora até o próximo halving, um evento no Bitcoin que ocorre aproximadamente a cada 210.000 blocos minerados, ou cerca de quatro anos. Durante o halving, a recompensa que os mineradores recebem por adicionar um novo bloco à blockchain é reduzida pela metade.
Um diagrama visual da mempool que mostra o estado das transações pendentes na rede.
Tamanhos de blocos
O tamanho de cada quadrado representa o tamanho da transação em bytes.
Filtros (Consolidação, Coinjoin, Dados): Permite visualizar categorias específicas de transações: * Consolidação: Transações de consolidação agrupam pequenos UTXOs em um único UTXO maior para simplificar e baratear futuras transações. (UTXOs merecem um artigo dedicado) * Coinjoin: Transações CoinJoin são usadas para melhorar a privacidade, misturando transações de vários usuários em uma única transação. * Dados: Mostra transações que contêm dados adicionais, que podem incluir informações não financeiras, como mensagens.
Este gráfico exibe o número de transações recebidas ao longo do tempo.
Taxa mínima (1 sat/vB):
Indica a taxa mínima atualmente aceita pela mempool. Se a mempool estiver cheia, transações que paguem menos do que a taxa mínima podem ser excluídas para dar lugar a transações de maior prioridade.
Uso de memória (259 MB / 300 MB):
A mempool tem um limite de memória. Quando está cheia, transações de taxa mais baixa podem ser descartadas para abrir espaço para aquelas com taxas mais altas, priorizando-as para inclusão em blocos.
Transações não confirmadas (59.361):
Indica o número total de transações pendentes que aguardam confirmação. Quanto maior o número de transações na mempool, maior a probabilidade de que as taxas aumentem para garantir uma confirmação mais rápida.
Essa seção mostra transações que foram substituídas utilizando o mecanismo RBF (Replace-By-Fee), que permite substituir uma transação com uma taxa mais alta para acelerar sua confirmação.
TXID
Este é o identificador da transação (Transaction ID), exibido parcialmente para abreviar o espaço. Cada transação tem um identificador único na blockchain.
Previous fee
Exibe a taxa de transação original paga na primeira tentativa, medida em satoshis por vByte (sat/vB). Esta taxa inicial provavelmente era baixa demais, resultando em uma demora na confirmação.
New fee
Mostra a nova taxa de transação, também em satoshis por vByte, definida para substituir a taxa anterior. Uma taxa maior aumenta as chances de inclusão rápida em um bloco.
Status (RBF)
RBF indica que a transação foi substituída utilizando o recurso "Replace-By-Fee". Isso significa que a nova transação cancelou e substituiu a original, e o minerador escolherá a transação com a taxa mais alta para incluir no próximo bloco.
Esta seção lista transações recentes que entraram na mempool e aguardam confirmação.
TXID
Similar ao "Recent Replacements", este é o identificador único da transação.
Amount
Exibe a quantidade de Bitcoin transferida nessa transação, geralmente em frações de BTC (como 0.0001 BTC). Esta é a quantia enviada pelo remetente ao destinatário.
USD
Mostra o valor da transação em dólares americanos (USD), calculado com base na taxa de câmbio atual. Serve para dar uma ideia de quanto a transação representa em moeda fiduciária.
Fee
Exibe a taxa de transação paga, em satoshis por vByte (sat/vB). Uma taxa mais alta em relação à média aumenta a probabilidade de confirmação mais rápida, pois as transações com taxas mais elevadas são priorizadas pelos mineradores.
E acabou. Espero que isso tenha sido útil para você e tenha agregado mais entendimento sobre esse complexo e maravilhoso mundo do Bitcoin. Se foi, considere compartilhar com alguém que precise. E se tem sugestões de melhoria, por favor, não deixe de comentar, o conhecimento está dispero na sociedade.
Por fim, stay humble and stack sats! -

2025-03-06 10:50:28Law of diminishing returns : ทำมากได้น้อย ซวยหน่อยขาดทุน
** หมายเหตุ บทความนี้มีเนื้อหาต่อเนื่องจาก “(TH) Why I quit : สาเหตุที่ผมลาออกจากที่(ทำงาน) ที่ (เคย) เรียกว่า”บ้าน” ใครยังไม่ได้อ่าน แนะนำให้ไปอ่านก่อนนะครับ
ผมได้ยิน คุณท็อป จิรายุส (คุณท๊อป บิทคับ) พูดคำว่า "Law of diminishing returns" ไว้ตอนแชร์มุมมองด้านการทำธุรกิจ ตอนนั้นผมไม่เข้าใจ แต่ผมรู้สึกว่ามันเป็นเจ๋งดี
สำหรับผม สรุปกฏนี้สั้นๆ คือ “ทำมากได้น้อย ซวยหน่อยขาดทุน”
กฏข้อนี้ว่าด้วยเรื่องการทำธุรกิจ พูดถึงปัจจัย 3 อย่าง - Fixed input คือสิ่งที่ไม่สามารถผลิตเพิ่มได้อีกในธุรกิจตอนนั้น เช่น จำนวนห้องตรวจในโรงพยาบาล, พื้นที่ที่ดินทำการเกษตร, ห้องเก็บสินค้า, จำนวนโต๊ะทำงานในสำนักงาน, ช่องบริการลูกค้าในธุรกิจบริการต่างๆ เป็นต้น ผมขอเรียกสั้นๆว่า “พื้นที่” - Variable input คือสิ่งที่สามารถเติมเข้ามาในธุรกิจได้ ปรับแต่งได้ เช่น แรงงาน เครื่องจักร พลังงาน - Marginal product คือผลลัพธ์ของธุรกิจ กำไรเพิ่มขึ้นหลังจากเพิ่ม variable input เข้าสู่ระบบ
ระยะของ law of diminishing returns
- Increased return (ทำเงินได้เยอะขึ้น) เมื่อป้อนแรงงานหรือเครื่องจักรเข้าสู่ระบบ ธุรกิจสามารถทำเงินเพิ่มขึ้นเนื่องจาก fixed input เดิมที่ถูกใช้สอยไม่เต็มที่ (underutilized) ถูกเติมเต็ม กรณีของรพ. คือมีห้องตรวจที่ว่าง ไม่มีหมอนั่งตรวจคนไข้ ห้องตรวจนั้นก็จะไม่สร้างรายได้ แต่เมื่อห้องนั้นมีหมอมานั่ง จะเปลี่ยนเป็นพื้นที่ที่ก่อให้เกิดรายได้ เมื่อห้องตรวจทุกห้องมีหมอนั่งครบ ถือว่าเต็มศักยภาพ ประสิทธิภาพการทำงานที่ดีตามมา
- Diminishing return (ทำมากได้น้อย) จุดของความพอดี (optimum point) คือจุดที่สมดุลพอดีของธุรกิจนั้น ทำกำไรได้เหมาะสม ไม่มากไม่น้อยจนเกินไป แต่ถ้ามองไม่เห็นจุด optimum นี้แล้วยังเพิ่ม”แรงงาน”เข้าไปอีก มันจะทำให้ ”พื้นที่” วุ่นวายเละเทะ ประสิทธิภาพในการทำงานลดลง
- Negative returns (ซวยหน่อยขาดทุน) ถ้ายังไม่หยุดเพิ่ม “แรงงาน” อีก สามารถนำมาสู่การขาดทุน
สรุปเป็นกราฟหน้าตาตามนี้ครับ
ทำไมมันถึงเป็นอย่างนั้น
ผมใช้โมเดลธุรกิจรพ.นี้เป็นตัวอย่างเลยนะครับ
ช่วงแรกที่สร้างรพ. ห้องตรวจมีไม่มาก จำนวนหมอและคนไข้สมดุลกันพอดี งานไม่หนักเกินไป การดูแลคนไข้มีประสิทธิภาพ รพ.เป็นที่ไว้ใจของคนในพื้นที่ มีชื่อเสียง ถูกบอกต่อ ทำให้จำนวนคนไข้เข้ามารับบริการมากขึ้น ต้องขยายพื้นที่รพ. สร้างตึกเพิ่ม รับบุคคลากรทุกระดับเข้ามาทำงานมากขึ้น จนเต็มพื้นที่ที่ดินรพ.ไม่สามารถขยายเพิ่มไปได้มากกว่านี้แล้ว เกิดสมดุลพอดี ทุกพื้นที่ถูกใช้งานเต็มศักยภาพ ประสิทธิภาพงานดีมาก
ผลการดำเนินงาน
ไม่เคยขาดทุน ผ่านช่วงวิกฤตต้มยำกุ้ง และ COVID ได้สบายๆ ฐานะทางการเงินแข็งแรง จ่ายปันผลสม่ำเสมอ ถ้าผมเป็นเจ้าของรพ.ผมจะ 1. สร้างระบบ 2. สร้างทีมผู้บริหาร 3. เน้นย้ำความสำคัญทำตามระบบ 3. Plan - Do- Check - Act เมื่อเกิดปัญหา
เพื่อให้ตัวผมสามารถถอยตัวเองออกมาจากตัวธุรกิจ คอยติดตาม monitor ทุกไตรมาส อย่างใกล้ชิด ไม่ทำอะไรเพิ่มไปมากกว่านี้
แต่สุดท้ายมันก็เกิดเหตุการณ์ทายาทรุ่นที่ 2 “ไม่เอา” นั่นแหละครับ มันทำให้วัฒนธรรมองค์กรเปลี่ยน ก้าวเท้าเข้าไปสู่ยุคตกต่ำ
บริหารแบบล้าหลัง ทำอะไรไม่สุด คิดว่าทำแล้วแต่จริงๆคือไม่ได้ทำ แก้ปัญหาไม่ตรงจุดสร้างปัญหากว่าเดิม
ตัวอย่าง
1. นโยบายการประหยัดพลังงานเพื่อลด carbon footprint
ฟังดูเหมือนจะดี แต่รพ.สื่อสารให้
รณรงค์ให้ปิดไฟ ... ปิดแอร์เมื่อไม่ใช้งาน ...
ผมว่าประโยคนี้มันคุ้นๆ เหมือนเคยได้ยินมามากกว่า 10 ปีแล้ว ... หรือผมเข้าใจผิดหรือเปล่าไม่แน่ใจ
รณรงค์แค่นี้แหละครับ เรื่องลด carbon footprint ไม่ได้เป็นการคิดอะไรใหม่ๆที่เหมาะกับยุคสมัย หรือสร้างอะไรที่จับต้องได้ (objective)
แต่สิ่งที่ทำสวนทางโดยสิ้นเชิงคือใช้พลาสติกแบบใช้แล้วทิ้ง (single use plastic) เป็นภาชนะหลักในการบรรจุอาหารของแพทย์ และผู้เข้าร่วมประชุมงานใหญ่ๆ
มีเสียงเสนอแนะจากบุคคลากรทุกระดับว่าให้ทำเป็นบุฟเฟ่ต์ จานชามช้อนส้อมแบบปกติก็ได้ เสนอกันมา 5 ปี ก็ยังคงไม่่มีการเปลี่ยนแปลง ได้รับแจ้งลงมาว่าใช้ภาชนะพลาสติกมันประหยัดกว่า เอาเป็นว่ากล่องข้าวพลาสติกมีการใช้อย่างน้อย 1200 กล่องต่อเดือน … คาดว่าสมการการปล่อยก๊าสคาร์บอน (carbon emission) ที่ทีมผู้บริหารคำนวณ อาจจะซับซ้อนเกินความเข้าใจของผมก็ได้นะครับ
2. การตลาดที่ล้มเหลวและพาแพทย์ซวย
ทำการตลาดไม่เข้าเป้า “เหมือนจะ” ทำ digital marketing แต่ทำแค่โพสกราฟฟิคโปรโมชั่นภาพนิ่งลงสื่อโซเชียลทุกช่องทาง แล้วบอกว่านั่นคือ digital marketing
... แต่เดี๋ยวก่อนๆๆๆ ...
ผมจะบอกว่าการโพสมันเป็นแค่ 1 ใน 10 ของ digital marketing แต่รพ.เข้าใจว่าตัวเองได้เข้าสู่ digital marketing แล้ว
... จริงๆมันไม่ใช่เลยเว้ย ...
ผลลัพธ์คือไม่สามารถเปิดน่านน้ำลูกค้าใหม่ได้เลย ได้แต่ฐานลูกค้าเดิมที่มี brand royalty (แต่แนวโน้มลดลง)
แถมที่แย่ที่สุดคือทำการตลาดแพคเกจออกมาโดยไม่ปรึกษาแพทย์ก่อนว่ามันขัดต่อมาตรฐานการรักษาหรือไม่ กลายเป็นทำแพคเกจดึงดูดคนไข้เข้ามาใช้บริการ แต่การรักษาในแพคเกจขัดต่อมาตรฐานการรักษาของแพทย์
คนไข้ไม่รู้หรอกครับ คนไข้จะเอาตามที่มีในแพคเกจ เขาจ่ายตังค์แล้ว แต่ความซวยมันไปตกอยู่กับแพทย์
3. วางกลยุทธไม่เข้าเป้า
ทุกๆต้นปีทางผู้บริหารจะประกาศกลยุทธประจำปี ว่าในปีนั้นๆรพ.จะมุ้งเน้นพัฒนาด้านไหน รพ.นี้มีปัญหาที่เป็นงูกินหางมานาน มันส่งผลต่อประสิทธิภาพการทำงานของหมอและพยาบาล มีการเสนอแก้ปัญหาเรื่องนี้วนซ้ำซากมา 5 ปี แต่ไม่ได้รับแก้ไขจริงจัง (ผมขอไม่เล่านะครับ)
แต่กลยุทธประจำปี 3 ปีที่ผ่านมา พุ่งใส่ตัวบุคคลากร เน้นพฤติกรรมบริการที่ดีเลิศ ทราบมาว่ามีการลงทุนกับโครงการนี้หลักแสนหรือหลักล้าน มีการจัด workshop เชิญวิทยากรและ trainer จากบริษัทภายนอก (outsource) เข้ามาอบรม เป็นโครงการที่เน้นให้บุคคลากรทุกคนเข้าอบรม 100%
ผมมองว่าปัญหาที่เป็นราก (root cause) มันยังไม่ถูกแก้เลย เปรียบเทียบเหมือนฐานรากของอาคารที่มันโคลงเคลงๆไม่มั่นคงยังไม่ได้รับการแก้ไข แต่พยายามตกแต่งห้องด้วยวัสดุคุณภาพดีและเทคโนโลยีที่ทันสมัย … แต่พร้อมจะล้มลงมาได้ทุกเมื่อ
4. มีเสน่ดึงดูด partner ใหม่ๆ แต่ไม่เอาเอง
ในช่วง COVID ระลอกแรก มีผู้นำทางด้านธุรกิจโรงแรมในจังหวัดมานำเสนอโมเดลธุรกิจ “hospitel เปลี่ยนโรงแรมให้เป็นโรงพยาบาล” ด้วยศักยภาพของรพ.ที่มีบุคคลากรเพียงพอ และตัวโรงแรมที่นำมาเสนอมีห้องพักประมาณ 300 ห้อง เป็นโมเดลที่รพ.และโรงแรม win-win ทั้งคู่ แต่ทางผู้บริหารมองว่าไม่คุ้ม ปฏิเสธข้อเสนอนี้ ทำให้เสียโอกาสให้กับคู่แข่งคว้าตลาด blue ocean นี้ไป
ผมได้แต่เกาหัวตอนรู้เรื่องนี้ เพราะ 1. ช่วง COVID คนไข้น้อย พนักงานโดนลดชั่วโมงการทำงาน ได้เงินเดือนขั้นต่ำ ไม่ได้ OT 2. ทาง partner เสนอขอบุคคลากรเหล่านี้แหละ ไปช่วยงาน เรื่องสถานที่ทางโรงแรมเขามีแม่บ้าน ฝ่ายทำความสะอาดอยู่แล้ว 3. ทาง partner เสนอ profit sharing กับทางรพ. ถึงผมจะไม่รู้ตัวเลข แต่เชื่อว่ามันยุติธรรม
ผมก็ไม่รู้ครับ ว่าอะไรคือคุ้มสำหรับผู้บริหาร
5. Top down absolute power
ไม่ฟังข้อเสนอจากตัวแทนหมอ คนที่มีอำนาจการตัดสินใจไม่เคยเอาตัวลงมาคุยกับหมอแบบจริงจังเลย
1-2 ปีจะลงมาพบหมอทั้งรพ.ซักหนึ่งครั้ง สร้างภาพเก่ง พูดขายฝันสวนหรูถึงภาพที่เขาต้องการ สั่งการลงมา พอเกิดปัญหาตัวเองไม่ลงมารับผิดชอบ แต่อาศัยหน่วยข่าวกรอง(ที่ไม่รู้ว่ากรองอะไรเข้าไปบ้าง) ออกคำสั่งแก้ผ้าเอาหน้ารอดลงมาทีหลัง
แถมสั่งให้เงียบและหุบปาก
ครั้งหนึ่งมีคำสั่งออกมาไม่ชัดเจน จนพยาบาลทำงานไม่ได้ ตัวแทนพยาบาลต้องโทรมาหาผมเพื่อให้ผมช่วย
ผมรวบรวมข้อมูลทั้งหมดและพบว่าคำสั่งมีปัญหาจริงๆ ผมจึง chat line ลงไปสอบถามผู้บริหารเพื่อขอความชัดเจน
… ผ่านไปไม่ถึง 5 นาที หนึ่งในผู้บริหาร(คนที่แทงข้างหลังผมที่หาว่าผมมาตรวจคนไข้ VIP เขาช้า 5 นาทีนั่นแหละ)โทรหาผมทันทีคุยกับผมสั้นๆ ใจความว่า “คำสั่งนั้นเอาแบบเดิม ไม่ต้องแก้ และให้ผมเงียบๆซะ”... (ก็ได้วะครับ)
จุดเปลี่ยนที่ทำให้รพ.เข้าสู่ law of diminishing returns
ห้องตรวจทุกห้องของรพ. ถูกใช้จนเต็มศักยภาพ … เอาจริงๆคือล้นศักยภาพเสียอีก (over-utilized) บางแผนกมีเก้าอี้ดนตรี - หมอคนแรกหมดเวลาออกตรวจ - หมอคนต่อไปเดินเข้าใช้ห้องตรวจต่อทันที - ถ้าไม่ทันก็ต้องคว้าห้องตรวจที่ว่างพร้อมใช้งานก่อน - หมอทำการไล่ที่กันเอง - หมอบางท่านต้องใช้ห้องทำงานของพยาบาลเป็นห้องตรวจชั่วคราว
ห้องพักผู้ป่วยก็เช่นกัน บางช่วงเตียงเต็มจนไม่สามารถ admit คนไข้ได้
แต่จำที่ผมบอกได้มั้ยครับว่า คนที่เป็น top down absolute power ไม่เคยเอาตัวลงมาพูดคุยกับแพทย์เพื่อรับฟังปัญหาที่แท้จริงเลย รับแต่ข่าวกรอง(ที่ไม่รู้ว่ากรองอะไรเข้าไปบ้าง) ช่วงนึงมีคนไข้ complaint ว่ารอนั่งรอหมอนาน หมอมาตรวจช้า ผู้บริหารเลยพยายามจะแก้ปัญหา โดยการ monitor waiting time (ระยะเวลารอหมอ) หยิบยกเรื่องนี้ขึ้นมาเป็นวาระเร่งด่วนต้องรีบแก้ไข
แต่เขายังงงๆกับ concept waiting time อยู่เลยว่าจะนับตั้งแต่ตอนไหนถึงตอนไหน - Waiting time สั้นแปลว่าดี เพราะคนไข้ได้เจอหมอเร็ว - Waiting time นานแปลว่าไม่ดี เพราะคนไข้นั่งรอหมอนาน
เขาตีความจากตัวเลขครับ แต่เคยเอาตัวลงมาดูจริงๆหรือเปล่าว่าทำไมตัวเลขมันถึงออกมาไม่ดี
คำตอบคือ“ไม่” ครับ
หมอบางสาขามีความจำเป็นต้องไปดูคนไข้ที่อาการหนักใช้เวลารักษานาน ... หรือ ... รับปรึกษาจากแพทย์ต่างสาขา ... หรือ ... เป็นสาขาเฉพาะทางของเฉพาะทางอีกที ต้องใช้เวลาตรวจละเอียดตรวจนาน
มันเป็นกระบวนการทำงานของหมอ ที่หมอด้วยกันเข้าใจกัน
ส่วนคนเก็บข้อมูลก็นำเสนอไปทั้งอย่างนั้นโดยที่ไม่ได้วิเคราะห์อะไรเลย มันเป็นการกรองข้อมูลที่ไม่รอบคอบก่อนนำเสนอผู้บริหาร
สุดท้ายผู้บริหาร “โทษหมอ” ว่าไม่มีการบริหารเวลาทำงานที่ดีเพียงพอ ทำให้คนไข้รอนาน เขาสรุปกันดื้อๆแบบนี้เลยครับ
พอหนักๆเข้า “รอหมอนาน ต้องเพิ่มหมอ” season การรับสมัครหมอหลายตำแหน่งได้เริ่มขึ้น
แต่เดี๋ยวนะ ห้องตรวจมันแน่นจนแทบไม่มีที่ให้หมอนั่งทำงานแล้ว แต่เขาก็ไม่สนครับ รับหมอหน้าใหม่ๆมาเพิ่มเรื่อยๆ
ด้วย mindset ว่า "ต้องเพิ่มหมอ หมอจะได้เยอะขึ้น คนไข้จะได้ไม่ต้องรอนาน" และเชื่อว่าจะทำรายได้ให้รพ.มากขึ้น หมอหน้าใหม่บางท่านเข้ามาทำงานวันแรกถึงขั้นอยู่ในสภาวะ dead air คือไม่มีที่ให้นั่งทำงาน
“ทำมากได้น้อย” เริ่มต้น
คนไข้รพ.นี้ ส่วนใหญ่เป็นโรคซับซ้อน ต้องการทักษะและเวลาหมอเฉพาะทางแต่ละสาขาอยู่ดี ไม่ได้ทำให้ waiting time ดีขึ้น คนไข้ยัง “นั่งรอหมอนานเหมือนเดิม”
รายได้เริ่มลดลง ยอดคนไข้เริ่มลดลง รพ.พยายามแก้เกมโดยการเพิ่มราคาค่าบริการ (เพิ่มขนาด ticket size) ทำให้มีเสียงรีวิวตามโซเชียลว่า "แพง"
ผลที่เกิดขึ้นคือคนไข้หลายคนอาศัยรพ.นี้ในการตรวจวินิจฉัยโรคแล้วเอาผลไปรักษาต่อรพ.รัฐบาลตามสิทธิ์เพราะสู้ราคาค่ารักษาไม่ไหว บางคนมีประกันสุขภาพหลายฉบับแต่ก็ต้องจ่ายส่วนต่างมากอยู่ดี
วิธีการข้างต้นนี้ ไม่ผิดกติกาครับ ผล X-ray , CT, MRI, ultrasound จากรพ.เอกชน ไวกว่ารพ.รัฐบาลอยู่แล้ว แต่ก็มีคนไข้บางส่วนยินดีจ่ายแพง เพราะเชื่อมั่นหมอที่รพ.นี้ไม่อยากย้ายรพ.ก็มีครับ เพราะหมอไม่ได้ทำอะไรผิด หมอเก่งๆมีเยอะ
ถึงแม้ว่ารพ.จะรักษา momentum มีจำนวนคนไข้ประมาณ 1100 - 1200 รายต่อวัน แต่ก็เป็นโรคง่ายๆ(simple disease) เช่นไข้หวัด อาหารเป็นพิษ เป็นต้น โรคเหล่านี้ ticket size ไม่ได้ใหญ่มาก ประคองไว้ไม่ให้ขาดทุนเท่านั้นครับ
แต่ความแพงแบบไม่สมเหตุสมผล ทำให้คนไข้หลายรายถอดใจย้ายรพ.ตั้งแต่ทราบค่าใช้จ่ายวินาทีแรก
คนไข้น้อยลง --> รายได้ลดลง --> เพิ่ม ticket size ต่อหัวให้แพงขึ้น --> คนไข้หนีเพราะแพงเกิน
ผมไม่รู้ว่าผู้บริหารเขาเห็นไหม แต่คาดว่าคงจะไม่เห็น
ส่วนโรคหรือการผ่าตัดที่สมศักดิ์ศรีกับศักยภาพของรพ. "น้อยมากจนแทบไม่มี" ไม่ใช่สาเหตุอื่นเลยครับ โดนรพ.คู่แข่งในรัศมี 20 กิโลเมตรเอาไปหมด เพราะราคาถูกกว่า หมอก็เก่งไม่แพ้กัน หมอบางคนเคยอยู่ที่รพ.แห่งนี้ เสนอโปรเจคการรักษาโรคบางโรคที่สามารถสร้างรายได้เป็นกอบเป็นกำ แต่ทางรพ.ไม่เอาเอง สุดท้ายหมอเหล่านั้นย้ายไปอยู่กับรพ.คู่แข่งและผลักดันโปรเจคเหล่านั้นสำเร็จจนมีชื่อเสียง
"รพ.ขายสินค้า premium ไม่ได้เลย ขายได้แต่สินค้าเกรดท้องตลาด"
กลยุทธที่รพ.ทำต่อมาคือเพิ่มจำนวนชั่วโมงการทำงานของหมอให้เพิ่มขึ้นโดยให้หมอมาทำงานเร็วขึ้น 2 ชม. แต่ไม่จ่าย OT ให้ ด้วยตรรกะว่าถ้าหมอทำงานนานขึ้น จะมีจำนวนคนไข้มากขึ้น ทางรพ.ไม่ได้ขอร้อง แต่บีบคอให้หมอร่วมมือ หากไม่ร่วมมือไล่ออกทันที
ไปๆมาๆ มีการไล่ออกกระทันหันเกิดขึ้น มีการส่งหนังสือส่วนตัวหาหมอทุกคน ใครมีรายชื่อที่จะปลดออกก็ต้องออกจากงานทันที
ผมมองว่าฐานะทางการเงินมีปัญหารุนแรงครับ เงินเดือนพนักงานถือเป็น fixed cost ที่ธุรกิจต้องแบกรับ ถ้าเจ๋งจริงต้องควบคุมรายจ่ายให้ธุรกิจสามารถไปต่อได้โดยไม่ปลดคน ในส่วนของธุรกิจรพ. หมอคือบุคคลากรที่สำคัญที่สุดและเป็นด่านสุดท้ายที่จะไล่ออกเพื่อรักษาชีวิตของธุรกิจ ตอนนี้รพ.ได้เข้าสู่ระยะสุดท้ายของ law of diminishing returns คือ “ซวยหน่อยขาดทุน” เป็นที่เรียบร้อยครับ
จุดจบของรพ.แบบนี้ ที่ศักยภาพดี แต่บริหารห่วยแตก มันจะจบด้วยการถูก take over ผ่านมาไม่นานกราฟหุ้นออกอาการ exit liquidity แล้วครับ
ข้อคิดที่อยากแบ่งปันกับทุกคนที่อ่านมาจนจบ
- ช่วงธุรกิจเปลี่ยนผ่านสู่ทายาท คือจุดวัดใจหัวเลี้ยวหัวต่อว่าจะรอดหรือไม่รอด
- Law of diminishing returns ไม่ได้ใช้เฉพาะกับธุรกิจ แต่สามารถประยุกต์ใช้กับการดำเนินชีวิตได้หลายมิติ หากใครเข้าใจ จะขยับเข้าสู่ Pareto’s rule … สั้นๆคือ ทำน้อยแต่ได้(โคตร)มาก
- เจ้าของธุรกิจ ต้องหูไว มองหาเนื้อร้ายที่คอยกัดกินธุรกิจให้เจอ แล้วกำจัดมันซะ ก่อนที่ธุรกิจจะล้มทั้งยืน ทับตัวเองตาย

2025-03-06 07:52:32It's been barely two years since I joined Nostr on my main npub, nostr:npub1kun5628raxpm7usdkj62z2337hr77f3ryrg9cf0vjpyf4jvk9r9smv3lhe, and in just that relatively short time, the amount of development on top of this protocol has been staggering. When nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m first opened the floodgates of adoption by tweeting about Nostr, it felt like most of the available clients were barely serviceable and held together with a prayer and copious amounts of duct tape. Of course, it can sometimes still feel that way, but there are definitely some Nostr apps looking and feeling more polished and providing true innovation when compared with legacy social platforms. Indeed, there are a growing number of Nostr-based applications and tools that have very little to do with social media at all.
One thing we have not had available to the growing Nostr community, and those considering joining it, is a source for application reviews that is thorough, approachable, knowledgeable, and balanced. This is what I hope to begin to provide through this new npub dedicated to reviewing as many of the Nostr clients, apps, and tools as I possibly can, so you the reader can determine which ones will fit your needs, and perhaps help you find new ones you had never heard about.
One of the best parts about Nostr is the portability of your identity and social graph, allowing users to log into any Nostr-based application with their same "account" without some centralized tech giant like Google or Apple owning who you are and all of your data. Leverage this super-power of Nostr with me as we explore the best applications and tools the intrepid developers building on this platform have cooked up.
What will you review?
My choice of applications to review will be based on a few factors.
First, I will only be reviewing applications that have a production release, or are otherwise considered production ready by the developer. nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s, you won't have to worry that I will be putting NoteDeck under the microscope while it is still very much in alpha. All of us who love to try the new clients as soon as they are available understand well enough that there will be plenty of bugs, UI quirks, and rough edges to look past.
Second, I will generally be reviewing applications that are meant to be user-facing for the average person. That is, apps that your normie friends might soon be using, and then asking you why they can't edit anything they post. I will not be doing reviews of various relay implementations, for instance, unless they are designed to be approachable to the average user to install and manage. nostr:npub10npj3gydmv40m70ehemmal6vsdyfl7tewgvz043g54p0x23y0s8qzztl5h, your project might just be a notable exception.
Third, my reviews will be limited by the operating systems I have available to me at the time. Sorry folks over on iOS, Mac, and Windows. I will only be able to review apps I can run on Android, Linux, or my web browser for the time being.
How will the apps be rated?
I want to be thorough in my reviews, and yet avoid overloading my readers with information they don't care about. In order to attempt to achieve this, I will break my reviews into several sections, so readers can skip to the sections relevant to their interests.
First, I will provide a basic overview of the type of application I am reviewing, what it is trying to achieve, and why a user might want to try it out.
Next, I will give my overall impression of the application. The good, the bad, and the ugly, as it were, so that those who just want a brief rundown can get the TLDR right out the gate and be on their way.
Then we will begin diving into the nitty-gritty with an in depth look at the main features of the application. What it does well. What features seem lacking. What expected features are absent. What features make it unique and set it apart from other applications with a similar purpose.
For the sake of all the baby Nostriches out there, the next section will be an assessment of how approachable the application would likely be to a normie who is coming to Nostr with no idea what a public and private key are, what relays are, or why they might want to start interacting here instead of on a legacy equivalent. What would someone used to Twitter think of #Snort? What would someone used to Spotify think of #Fountain or #Wavlake?
The next section will be a review of the application's UI. The design and polish. How easy it is to find the things you want in the areas you would expect them. In short, how well the application achieves the goal of making the user feel at home and want to continue using the app just through quality UI design.
If you know me and my contstant harping on developers to include various forms of external signing, it should be no surprise to you that the next section will cover login options. What does the sign-in and sign-up flow look like, and does the user have to expose their private key to the application in order to use it?
A review of virtually any Nostr application would be incomplete without a section dedicated to zap integration. How prominent is zapping in the app? How easy is it to zap or start receiving zaps? Are zaps displayed in a way that encourages users to compete to be top zapper? Is Nostr Wallet Connect supported for using external wallets for one-tap-zapping?
Most Nostr applications, even "other stuff" clients, are designed to present some form of content to the user. The next section will cover how easy it is for the user to find the type of content they may be interested in, or to discover content they didn't know they might be interested in. For social clients, how easy is it to discover other users that they might want to follow?
The backbone of the protocol is the interplay between clients and relays, and the next section of the review will cover how the app manages relays. Are they hidden from the user? Are there sensible defaults? Can users who want to do so select the relays they prefer? Does the app respect relays the user has selected in other apps, or are the app's relays independent of those selected in other apps. Worse, does the app overwrite your selected relays with its defaults?
Finally, I will scour the #AskNostr feed for questions and comments from other users about the app under review to get more perspectives than just my own. What are the common pain-points other users are having? What do they love about the app? What features would they like to see added?
Are there other sections you would like to see me add before I start dropping reviews? Get them to me soon, because I am currently taking notes for my first review, which will be the #Primal #Android client!

2025-03-04 22:19:29War is rarely (or if ever) the will of the people. Throughout history, wars have been orchestrated by political and economic elites, while the media plays a key role in shaping public opinion. World War I is a clear example of how propaganda was used to glorify war, silence dissent, and demonize the enemy.
Today, we see similar tactics being used in the Ukrainian War. The media spreads one-sided narratives, censors alternative views, and manipulates public sentiment. This article argues that wars are decided from the top, and media is used to justify them.
How the Media Glorified and Propagated WW1
The Media Sold War as an Adventure
Before WW1, newspapers and propaganda made war seem noble and exciting. Young men were encouraged to enlist for honor and glory. Posters displayed slogans like “Your Country Needs You”, making war look like a duty rather than a tragedy.
Demonization of the Enemy
Governments and media portrayed Germans as "barbaric Huns," spreading exaggerated stories like the "Rape of Belgium," where German soldiers were accused of horrific war crimes—many later proven false. Today, Russia is painted as purely evil, while NATO’s role and Ukraine’s internal conflicts are ignored.
Social Pressure & Nationalism
Anyone who opposed WW1 was labeled a traitor. Conscientious objectors were shamed, jailed, or even executed. The same happens today—if you question support for Ukraine, you are called "pro-Russian" or "anti-European." In the U.S., opposing war is falsely linked to supporting Trump or extremism.
Fabricated Stories
During WW1, fake reports of German soldiers killing babies were widely spread. In Ukraine, reports of massacres and war crimes often circulate without verification, while Ukrainian war crimes receive little coverage.
How the Media Promotes War Today: The Case of Ukraine
One-Sided Narratives
The media presents Ukraine as a heroic struggle against an evil invader, ignoring the 2014 coup, the Donbas conflict, and NATO expansion. By simplifying the issue, people are discouraged from questioning the full story.
Censorship and Suppression of Dissent
During WW1, anti-war activists were jailed. Today, journalists and commentators questioning NATO’s role face censorship, deplatforming, or cancellation.
Selective Coverage
Media highlights civilian deaths in Ukraine but ignores similar suffering in Yemen, Syria, or Palestine. Coverage depends on political interests, not humanitarian concern.
Glorification of War Efforts
Ukrainian soldiers—even extremist groups—are painted as heroes. Meanwhile, peace negotiations and diplomatic efforts receive little attention.
War is a Top-Down Decision, Not the Will of the People
People Don’t Want Wars
If given a choice, most people would reject war. Examples:
- Before WW1: Many workers and socialists opposed war, but governments ignored them.
- Vietnam War: Protests grew, but the war continued.
- Iraq War (2003): Millions protested, yet the invasion went ahead.
Small Elites Decide War
Wars benefit arms manufacturers, politicians, and corporate interests—not ordinary people. Public opposition is often ignored or crushed.
Manipulation Through Fear
Governments use fear to justify war: “If we don’t act now, it will be too late.” This tactic was used in WW1, the Iraq War, and is used today in Ukraine.
Violence vs. War: A Manufactured Conflict
Violence Happens, But War is Manufactured
Conflicts and disputes are natural, but large-scale war is deliberately planned using propaganda and logistical preparation.
War Requires Justification
If war were natural, why does it need massive media campaigns to convince people to fight? Just like in WW1, today’s wars rely on media narratives to gain support.
The Crimea Referendum: A Case of Ignored Democracy
Crimea’s 2014 Referendum
- Over 90% of Crimeans voted to join Russia in 2014.
- Western governments called it "illegitimate," while similar referendums (like in Kosovo) were accepted.
The Contradiction in Democracy
- If democracy is sacred, why ignore a clear vote in Crimea?
- Other examples: Brexit was resisted, Catalonia’s referendum was shut down, and peace referendums were dismissed when they didn’t fit political interests.
- Democracy is used as a tool when convenient.
VII. The Libertarian Case Against War
The Non-Aggression Principle (NAP)
Libertarianism is fundamentally opposed to war because it violates the Non-Aggression Principle (NAP)—the idea that no person or institution has the right to initiate force against another. War, by its very nature, is the ultimate violation of the NAP, as it involves mass killing, destruction, and theft under the guise of national interest.
War is State Aggression
- Governments wage wars, not individuals. No private citizen would naturally start a conflict with another country.
- The state forces people to fund wars through taxation, violating their economic freedom.
- Conscription, used in many wars, is nothing more than state-sponsored slavery, forcing individuals to fight and die for political goals they may not support.
War Creates Bigger Government
- War expands state power, eroding civil liberties (e.g., WW1's Espionage Act, the Patriot Act after 9/11).
- The military-industrial complex grows richer while taxpayers foot the bill.
- Emergency powers granted during wars rarely get repealed after conflicts end, leaving citizens with fewer freedoms.
Peaceful Trade vs. War
- Libertarians advocate for free trade as a means of cooperation. Countries that trade are less likely to go to war.
- Wars destroy wealth and infrastructure, while peaceful trade increases prosperity for all.
- Many wars have been fought not for defense, but for economic interests, such as securing oil, resources, or geopolitical power.
Who Benefits from War?
- Not the people, who suffer death, destruction, and economic hardship.
- Not small businesses or workers, who bear the burden of inflation and taxes to fund wars.
- Not individual liberty, as war leads to greater state control and surveillance.
- Only the elites, including defense contractors, politicians, and bankers, who profit from war and use it to consolidate power.
Conclusion: The Media’s Role in War is Crucial
Wars don’t happen naturally—they are carefully planned and sold to the public using propaganda, fear, and nationalism.
- WW1 and Ukraine prove that media is key to war-making.
- The media silences peace efforts and glorifies conflict.
- If people truly had a choice, most wars would never happen.
To resist this, we must recognize how we are manipulated and reject the forced narratives that push us toward war.

2025-02-25 15:20:39If you don't know where your posts are, you might as well just stay in the centralized Twitter. You either take control of your relay lists, or they will control you. Amethyst offers several lists of relays for our users. We are going to go one by one to help clarify what they are and which options are best for each one.
Public Home/Outbox Relays
Home relays store all YOUR content: all your posts, likes, replies, lists, etc. It's your home. Amethyst will send your posts here first. Your followers will use these relays to get new posts from you. So, if you don't have anything there, they will not receive your updates.
Home relays must allow queries from anyone, ideally without the need to authenticate. They can limit writes to paid users without affecting anyone's experience.
This list should have a maximum of 3 relays. More than that will only make your followers waste their mobile data getting your posts. Keep it simple. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of all your content in a place no one can delete. Go to relay.tools and never be censored again. - 1 really fast relay located in your country: paid options like http://nostr.wine are great
Do not include relays that block users from seeing posts in this list. If you do, no one will see your posts.
Public Inbox Relays
This relay type receives all replies, comments, likes, and zaps to your posts. If you are not getting notifications or you don't see replies from your friends, it is likely because you don't have the right setup here. If you are getting too much spam in your replies, it's probably because your inbox relays are not protecting you enough. Paid relays can filter inbox spam out.
Inbox relays must allow anyone to write into them. It's the opposite of the outbox relay. They can limit who can download the posts to their paid subscribers without affecting anyone's experience.
This list should have a maximum of 3 relays as well. Again, keep it small. More than that will just make you spend more of your data plan downloading the same notifications from all these different servers. Out of the 3 relays, I recommend: - 1 large public, international relay: nos.lol, nostr.mom, relay.damus.io, etc. - 1 personal relay to store a copy of your notifications, invites, cashu tokens and zaps. - 1 really fast relay located in your country: go to nostr.watch and find relays in your country
Terrible options include: - nostr.wine should not be here. - filter.nostr.wine should not be here. - inbox.nostr.wine should not be here.
DM Inbox Relays
These are the relays used to receive DMs and private content. Others will use these relays to send DMs to you. If you don't have it setup, you will miss DMs. DM Inbox relays should accept any message from anyone, but only allow you to download them.
Generally speaking, you only need 3 for reliability. One of them should be a personal relay to make sure you have a copy of all your messages. The others can be open if you want push notifications or closed if you want full privacy.
Good options are: - inbox.nostr.wine and auth.nostr1.com: anyone can send messages and only you can download. Not even our push notification server has access to them to notify you. - a personal relay to make sure no one can censor you. Advanced settings on personal relays can also store your DMs privately. Talk to your relay operator for more details. - a public relay if you want DM notifications from our servers.
Make sure to add at least one public relay if you want to see DM notifications.
Private Home Relays
Private Relays are for things no one should see, like your drafts, lists, app settings, bookmarks etc. Ideally, these relays are either local or require authentication before posting AND downloading each user\'s content. There are no dedicated relays for this category yet, so I would use a local relay like Citrine on Android and a personal relay on relay.tools.
Keep in mind that if you choose a local relay only, a client on the desktop might not be able to see the drafts from clients on mobile and vice versa.
Search relays:
This is the list of relays to use on Amethyst's search and user tagging with @. Tagging and searching will not work if there is nothing here.. This option requires NIP-50 compliance from each relay. Hit the Default button to use all available options on existence today: - nostr.wine - relay.nostr.band - relay.noswhere.com
Local Relays:
This is your local storage. Everything will load faster if it comes from this relay. You should install Citrine on Android and write ws://localhost:4869 in this option.
General Relays:
This section contains the default relays used to download content from your follows. Notice how you can activate and deactivate the Home, Messages (old-style DMs), Chat (public chats), and Global options in each.
Keep 5-6 large relays on this list and activate them for as many categories (Home, Messages (old-style DMs), Chat, and Global) as possible.
Amethyst will provide additional recommendations to this list from your follows with information on which of your follows might need the additional relay in your list. Add them if you feel like you are missing their posts or if it is just taking too long to load them.
My setup
Here's what I use: 1. Go to relay.tools and create a relay for yourself. 2. Go to nostr.wine and pay for their subscription. 3. Go to inbox.nostr.wine and pay for their subscription. 4. Go to nostr.watch and find a good relay in your country. 5. Download Citrine to your phone.
Then, on your relay lists, put:
Public Home/Outbox Relays: - nostr.wine - nos.lol or an in-country relay. -
.nostr1.com Public Inbox Relays - nos.lol or an in-country relay -
.nostr1.com DM Inbox Relays - inbox.nostr.wine -
.nostr1.com Private Home Relays - ws://localhost:4869 (Citrine) -
.nostr1.com (if you want) Search Relays - nostr.wine - relay.nostr.band - relay.noswhere.com
Local Relays - ws://localhost:4869 (Citrine)
General Relays - nos.lol - relay.damus.io - relay.primal.net - nostr.mom
And a few of the recommended relays from Amethyst.
Final Considerations
Remember, relays can see what your Nostr client is requesting and downloading at all times. They can track what you see and see what you like. They can sell that information to the highest bidder, they can delete your content or content that a sponsor asked them to delete (like a negative review for instance) and they can censor you in any way they see fit. Before using any random free relay out there, make sure you trust its operator and you know its terms of service and privacy policies.

2025-04-27 22:12:47In our time, the contest for power no longer occurs only on battlefields or in parliaments—it plays out in prices, in language, in data. The house isn’t just stacking chips, it’s stacking the deck, cornering the very mechanisms by which society functions. Land, homes, energy, education, and even knowledge itself—all are subject to capture.
Is this a market failure, or a feature of the system? What does it look like when the relentless outcompeting of the many by the few is engineered through policy, shielded by narrative, and sanctified by language? Turns out it looks a lot like a squeeze. Not a short squeeze, mind you; more like The Great Squeeze—a persistent pressure that pushes working people to the margins, misdiagnosed and mislabeled as “inflation.”
Yes, inflation does occur. There are places and times when too much money chases too few goods. But is this one of them? Are prices rising because money is being printed—or because access is being restricted? If everyone is in debt—individuals, governments—then who holds the credit? And if inflation is always theft, who’s doing the stealing when wages stay flat, but asset prices soar?
No matter who it is, the fact remains: rather than address the root causes of system degradation—decades of financialization, institutional capture, and compounding inequality—central banks and their institutional allies have chosen a more subtle form of defense: narrative control. They tell us this is “normal.” That it’s inflation, and that inflation is your fault: your wages, your spending, your expectations. They hijack language. What was once considered progressive is now politicized, and what was once nuanced is often reduced to labels. A squeeze—deep and systemic—is redefined as a passing issue, obscuring the real, lasting pressures at play.
But in a digital age, truth is no longer scarce. Information is everywhere. We have access to more knowledge than any civilization before us. What we lack is not breadth—but depth. Not information, but conviction.
So how do we express this conviction? How do we resist tyranny—not with weapons, but with wisdom?
The answer may lie not in more experts or more arguments, but in markets of meaning.
Prediction Markets: A 21st Century Arsenal
1. The Wisdom of Crowds
A well-designed prediction market draws on the intelligence of thousands. Not in the chaotic swirl of social media noise, but through price discovery in belief. Here, truth isn’t shouted—it’s traded. When people put their money where their minds are, the collective signal becomes stronger than any headline.
2. Detecting Corruption Through Betting Patterns
Sports betting has exposed match-fixing before any referee or journalist. Irregular patterns in the odds don’t lie. If corruption leaves fingerprints, prediction markets can trace them—not just in games, but in elections, economic forecasts, and geopolitical risk. They are early warning systems for deceit.
3. Realigning the Incentives of Economists
Today’s economists often live in silos—publishing obscure models, advising hedge funds, and rarely facing consequences for being wrong. Prediction markets flip this dynamic: the best ideas win not through peer review, but public wagers. Incentives shift. The public gets access to live, evolving consensus, scored not in rhetoric but returns.
The Right to Bear Knowledge
The Second Amendment was written in an age of muskets, when tyranny came with boots and banners. Today, it comes with metrics and models. The new tyranny is epistemic—a war for control over what is known, and who gets to know it.
In this context, the right to bear arms must evolve into a right to bear knowledge.
Prediction markets are more than speculative tools. They are instruments of civic resistance. They give individuals power not just to observe the future, but to shape it—to challenge official narratives, expose falsehoods, and re-anchor the public’s sense of reality in evidence, not authority.
To bet on truth is not to gamble. It is to believe—publicly, financially—in what you can defend.
This is a novel case, but not a radical one. It simply returns us to the roots of democracy: a system built on informed citizens, capable of seeing through deception.
In a world where the elite privatize truth, prediction markets offer the public a chance to own it.
To bear knowledge is to be armed. To trade on truth is to be free.
Let the market speak— But let it be one we create.

@ a2eddb26:e2868a80
2025-02-20 20:28:46In personal finance, the principles of financial independence and time sovereignty (FITS) empower individuals to escape the debt-based cycle that forces them into perpetual work. What if companies could apply the same principles? What if businesses, instead of succumbing to the relentless push for infinite growth, could optimize for real demand?
This case study of the GPU industry aims to show that fiat-driven incentives distort technological progress and imagines an alternative future built on sound money.
Fiat Business: Growth or Death
Tech companies no longer optimize for efficiency, longevity, or real user needs. Instead, under a fiat system, they are forced into a perpetual growth model. If NVIDIA, AMD, or Intel fail to show revenue expansion, their stock price tanks. Let's take NVIDIA's GPUs as an example. The result is predictable:
- GPUs that nobody actually needs but everyone is told to buy.
- A focus on artificial benchmarks instead of real-world performance stability.
- Endless FPS increases that mean nothing for 99% of users.
The RTX 5090 is not for gamers. It is for NVIDIA’s quarterly earnings. This is not a surprise on a fiat standard.
Fiat Marketing: The Illusion of Need and the Refresh Rate Trap
Benchmarks confirm that once a GPU maintains 120+ FPS in worst-case scenarios, additional performance gains become irrelevant for most players. This level of capability was reached years ago. The problem is that efficiency does not sell as easily as bigger numbers.
This extends beyond raw GPU power and into the display market, where increasing refresh rates and resolutions are marketed as critical upgrades, despite diminishing real-world benefits for most users. While refresh rates above 120Hz may offer marginal improvements for competitive esports players, the average user sees little benefit beyond a certain threshold. Similarly, 8K resolutions are pushed as the next frontier, even though 4K remains underutilized due to game optimization and hardware constraints. This is why GPUs keep getting bigger, hotter, and more expensive, even when most gamers would be fine with a card from five years ago. It is why every generation brings another “must-have” feature, regardless of whether it impacts real-world performance.
Marketing under fiat operates on the principle of making people think they need something they do not. The fiat standard does not just distort capital allocation. It manufactures demand by exaggerating the importance of specifications that most users do not truly need.
The goal is not technological progress but sales volume. True innovation would focus on meaningful performance gains that align with actual gaming demands, such as improving latency, frame-time consistency, and efficient power consumption. Instead, marketing convinces consumers they need unnecessary upgrades, driving them into endless hardware cycles that favor stock prices over user experience.
They need the next-gen cycle to maintain high margins. The hardware is no longer designed for users. It is designed for shareholders. A company operating on sound money would not rely on deceptive marketing cycles. It would align product development with real user needs instead of forcing artificial demand.
The Shift to AI
For years, GPUs were optimized for gaming. Then AI changed everything. OpenAI, Google, and Stability AI now outbid consumers for GPUs. The 4090 became impossible to find, not because of gamers, but because AI labs were hoarding them.
The same companies that depended on the consumer upgrade cycle now see their real profits coming from data centers. Yet, they still push gaming hardware aggressively. However, legitimate areas for improvement do exist. While marketing exaggerates the need for higher FPS at extreme resolutions, real gaming performance should focus on frame stability, low latency, and efficient rendering techniques. These are the areas where actual innovation should be happening. Instead, the industry prioritizes artificial performance milestones to create the illusion of progress, rather than refining and optimizing for the gaming experience itself. Why?
Gamers Fund the R&D for AI and Bear the Cost of Scalping
NVIDIA still needs gamers, but not in the way most think. The gaming market provides steady revenue, but it is no longer the priority. With production capacity shifting toward AI and industrial clients, fewer GPUs are available for gamers. This reduced supply has led to rampant scalping, where resellers exploit scarcity to drive up prices beyond reasonable levels. Instead of addressing the issue, NVIDIA benefits from the inflated demand and price perception, creating an even stronger case for prioritizing enterprise sales. Gaming revenue subsidizes AI research. The more RTX cards they sell, the more they justify pouring resources into data-center GPUs like the H100, which generate significantly higher margins than gaming hardware.
AI dictates the future of GPUs. If NVIDIA and AMD produced dedicated gamer-specific GPUs in higher volumes, they could serve that market at lower prices. But in the fiat-driven world of stockholder demands, maintaining artificially constrained supply ensures maximum profitability. Gamers are left paying inflated prices for hardware that is no longer built with them as the primary customer. That is why GPU prices keep climbing. Gamers are no longer the main customer. They are a liquidity pool.
The Financial Reality
The financial reports confirm this shift: NVIDIA’s 2024 fiscal year saw a 126% revenue increase, reaching \$60.9 billion. The data center segment alone grew 217%, generating \$47.5 billion. (Source)
The numbers make it clear. The real money is in AI and data centers, not gaming. NVIDIA has not only shifted its focus away from gamers but has also engaged in financial engineering to maintain its dominance. The company has consistently engaged in substantial stock buybacks, a hallmark of fiat-driven financial practices. In August 2023, NVIDIA announced a \$25 billion share repurchase program, surprising some investors given the stock's significant rise that year. (Source) This was followed by an additional \$50 billion buyback authorization in 2024, bringing the total to \$75 billion over two years. (Source)
These buybacks are designed to return capital to shareholders and can enhance earnings per share by reducing the number of outstanding shares. However, they also reflect a focus on short-term stock price appreciation rather than long-term value creation. Instead of using capital for product innovation, NVIDIA directs it toward inflating stock value, ultimately reducing its long-term resilience and innovation potential. In addition to shifting production away from consumer GPUs, NVIDIA has also enabled AI firms to use its chips as collateral to secure massive loans. Lambda, an AI cloud provider, secured a \$500 million loan backed by NVIDIA's H200 and Blackwell AI chips, with financing provided by Macquarie Group and Industrial Development Funding. (Source)
This practice mirrors the way Bitcoin miners have used mining hardware as collateral, expecting continuous high returns to justify the debt. GPUs are fast-depreciating assets that lose value rapidly as new generations replace them. Collateralizing loans with such hardware is a high-risk strategy that depends on continued AI demand to justify the debt. AI firms borrowing against them are placing a leveraged bet on demand staying high. If AI market conditions shift or next-generation chips render current hardware obsolete, the collateral value could collapse, leading to cascading loan defaults and liquidations.
This is not a sound-money approach to business. It is fiat-style quicksand financialization, where loans are built on assets with a limited shelf life. Instead of focusing on sustainable capital allocation, firms are leveraging their future on rapid turnover cycles. This further shifts resources away from gamers, reinforcing the trend where NVIDIA prioritizes high-margin AI sales over its original gaming audience.
At the same time, NVIDIA has been accused of leveraging anti-competitive tactics to maintain its market dominance. The GeForce Partner Program (GPP) launched in 2018 sought to lock hardware partners into exclusive deals with NVIDIA, restricting consumer choice and marginalizing AMD. Following industry backlash, the program was canceled. (Source)
NVIDIA is not merely responding to market demand but shaping it through artificial constraints, financialization, and monopolistic control. The result is an industry where consumers face higher prices, limited options, and fewer true innovations as companies prioritize financial games over engineering excellence.
On this basis, short-term downturns fueled by stock buybacks and leveraged bets create instability, leading to key staff layoffs. This forces employees into survival mode rather than fostering long-term innovation and career growth. Instead of building resilient, forward-looking teams, companies trapped in fiat incentives prioritize temporary financial engineering over actual product and market development.
A Sound Money Alternative: Aligning Incentives
Under a sound money system, consumers would become more mindful of purchases as prices naturally decline over time. This would force businesses to prioritize real value creation instead of relying on artificial scarcity and marketing hype. Companies would need to align their strategies with long-term customer satisfaction and sustainable engineering instead of driving demand through planned obsolescence.
Imagine an orange-pilled CEO at NVIDIA. Instead of chasing infinite growth, they persuade the board to pivot toward sustainability and long-term value creation. The company abandons artificial product cycles, prioritizing efficiency, durability, and cost-effectiveness. Gaming GPUs are designed to last a decade, not three years. The model shifts to modular upgrades instead of full replacements. Pricing aligns with real user needs, not speculative stock market gains.
Investors initially panic. The stock takes a temporary hit, but as consumers realize they no longer need to upgrade constantly, brand loyalty strengthens. Demand stabilizes, reducing volatility in production and supply chains. Gamers benefit from high-quality products that do not degrade artificially. AI buyers still access high-performance chips but at fair market prices, no longer subsidized by forced consumer churn.
This is not an abstract vision. Businesses could collateralize loans with Bitcoin. Companies could also leverage highly sought-after end products that maintain long-term value. Instead of stock buybacks or anti-competitive practices, companies would focus on building genuine, long-term value. A future where Bitcoin-backed reserves replace fiat-driven financial engineering would stabilize capital allocation, preventing endless boom-bust cycles. This shift would eliminate the speculative nature of AI-backed loans, fostering financial stability for both borrowers and lenders.
Sound money leads to sound business. When capital allocation is driven by real value rather than debt-fueled expansion, industries focus on sustainable innovation rather than wasteful iteration.
Reclaiming Time Sovereignty for Companies
The fiat system forces corporations into unsustainable growth cycles. Companies that embrace financial independence and time sovereignty can escape this trap and focus on long-term value.
GPU development illustrates this distortion. The RTX 3080 met nearly all gaming needs, yet manufacturers push unnecessary performance gains to fuel stock prices rather than improve usability. GPUs are no longer designed for gamers but for AI and enterprise clients, shifting NVIDIA’s priorities toward financial engineering over real innovation.
This cycle of GPU inflation stems from fiat-driven incentives—growth for the sake of stock performance rather than actual demand. Under a sound money standard, companies would build durable products, prioritizing efficiency over forced obsolescence.
Just as individuals can reclaim financial sovereignty, businesses can do the same. Embracing sound money fosters sustainable business strategies, where technology serves real needs instead of short-term speculation.

2025-04-27 16:51:37Not everyone agrees or realizes that governments, corporations and banks are progressively infringing on our most basic rights and that we should fight back, if only with the right tools.
But I don’t believe in going out in the street to protest, hoping that the government will do something about it. I think that demanding from the State is actually giving it even more power. So what’s the solution?
I believe that Bitcoin is the best tool for individuals to reclaim their freedom and sovereignty.
By taking money out of the hands of central banks, 3-letter agencies and governments, we can reclaim complete control over our money, our life and our future.
I believe the world is facing a great threat. I’m not talking about global warming or climate change. I’m talking about a global political agenda, shared among Western countries’ governments, and focused on limiting individual freedom while increasing government control.
I believe our modern banking and financial systems are profoundly inegalitarian by nature, with the ability for a few elites to “print” money out of thin air and use it to follow their own agenda.
I believe our modern banking system was built like this on purpose. I do not consider the government’s and central banks’ money printing to be part of “how things normally work”, but rather to be a counterfeiting mechanism that they use for their own benefit.
For these reasons, I don’t believe that governments have the people’s best interest in mind. As a matter of fact, I rather think the opposite is true.
I believe this counterfeiting mechanism (or money printing) leads to financial servitude for the individuals, and systemic risk for human society as a whole.
I believe all the financial crises we witnessed since the beginning of the 20th century are directly linked to this counterfeiting mechanism, and that this system is now coming to an end.
As such, I believe most people grossly overlook the risks that are being taken with their money, whether it be sitting on a bank account or invested in financial markets.
Furthermore, I believe this flawed monetary system is in complete control of most people’s money, lives, and future.
But I believe there is an alternative to this flawed system: Bitcoin.
I believe Bitcoin is the best tool individuals can use to take back their freedom and resist government controlling their life.
And I believe you shouldn’t have to be tech-savvy to start using Bitcoin, but you definitely need to be freedom-minded.

2025-02-18 20:30:32For the last couple of weeks, I've been dealing with the fallout of upgrading a web application to Svelte 5. Complaints about framework churn and migration annoyances aside, I've run into some interesting issues with the migration. So far, I haven't seen many other people register the same issues, so I thought it might be constructive for me to articulate them myself.
I'll try not to complain too much in this post, since I'm grateful for the many years of Svelte 3/4 I've enjoyed. But I don't think I'll be choosing Svelte for any new projects going forward. I hope my reflections here will be useful to others as well.
If you're interested in reproductions for the issues I mention here, you can find them below.
The Need for Speed
To start with, let me just quickly acknowledge what the Svelte team is trying to do. It seems like most of the substantial changes in version 5 are built around "deep reactivity", which allows for more granular reactivity, leading to better performance. Performance is good, and the Svelte team has always excelled at reconciling performance with DX.
In previous versions of Svelte, the main way this was achieved was with the Svelte compiler. There were many ancillary techniques involved in improving performance, but having a framework compile step gave the Svelte team a lot of leeway for rearranging things under the hood without making developers learn new concepts. This is what made Svelte so original in the beginning.
At the same time, it resulted in an even more opaque framework than usual, making it harder for developers to debug more complex issues. To make matters worse, the compiler had bugs, resulting in errors which could only be fixed by blindly refactoring the problem component. This happened to me personally at least half a dozen times, and is what ultimately pushed me to migrate to Svelte 5.
Nevertheless, I always felt it was an acceptable trade-off for speed and productivity. Sure, sometimes I had to delete my project and port it to a fresh repository every so often, but the framework was truly a pleasure to use.
Svelte is not Javascript
Svelte 5 doubled down on this tradeoff — which makes sense, because it's what sets the framework apart. The difference this time is that the abstraction/performance tradeoff did not stay in compiler land, but intruded into runtime in two important ways:
- The use of proxies to support deep reactivity
- Implicit component lifecycle state
Both of these changes improved performance and made the API for developers look slicker. What's not to like? Unfortunately, both of these features are classic examples of a leaky abstraction, and ultimately make things more complex for developers, not less.
Proxies are not objects
The use of proxies seems to have allowed the Svelte team to squeeze a little more performance out of the framework, without asking developers to do any extra work. Threading state through multiple levels of components without provoking unnecessary re-renders in frameworks like React is an infamously difficult chore.
Svelte's compiler avoided some of the pitfalls associated with virtual DOM diffing solutions, but evidently there was still enough of a performance gain to be had to justify the introduction of proxies. The Svelte team also seems to argue that their introduction represents an improvement in developer experience:
we... can maximise both efficiency and ergonomics.
Here's the problem: Svelte 5 looks simpler, but actually introduces more abstractions.
Using proxies to monitor array methods (for example) is appealing because it allows developers to forget all the goofy heuristics involved with making sure state was reactive and just
push
to the array. I can't count how many times I've writtenvalue = value
to trigger reactivity in svelte 4.In Svelte 4, developers had to understand how the Svelte compiler worked. The compiler, being a leaky abstraction, forced its users to know that assignment was how you signaled reactivity. In svelte 5, developers can just "forget" about the compiler!
Except they can't. All the introduction of new abstractions really accomplishes is the introduction of more complex heuristics that developers have to keep in their heads in order to get the compiler to act the way they want it to.
In fact, this is why after years of using Svelte, I found myself using Svelte stores more and more often, and reactive declarations less. The reason being that Svelte stores are just javascript. Calling
update
on a store is simple, and being able to reference them with a$
was just a nice bonus — nothing to remember, and if I mess up the compiler yells at me.Proxies introduce a similar problem to reactive declarations, which is that they look like one thing but act like another on the edges.
When I started using Svelte 5, everything worked great — until I tried to save a proxy to indexeddb, at which point I got a
DataCloneError
. To make matters worse, it's impossible to reliably tell if something is aProxy
withouttry/catch
ing a structured clone, which is a performance-intensive operation.This forces the developer to remember what is and what isn't a Proxy, calling
$state.snapshot
every time they pass a proxy to a context that doesn't expect or know about them. This obviates all the nice abstractions they gave us in the first place.Components are not functions
The reason virtual DOM took off way back in 2013 was the ability to model your application as composed functions, each of which takes data and spits out HTML. Svelte retained this paradigm, using a compiler to sidestep the inefficiencies of virtual DOM and the complexities of lifecycle methods.
In Svelte 5, component lifecycles are back, react-hooks style.
In React, hooks are an abstraction that allows developers to avoid writing all the stateful code associated with component lifecycle methods. Modern React tutorials universally recommend using hooks instead, which rely on the framework invisibly synchronizing state with the render tree.
While this does result in cleaner code, it also requires developers to tread carefully to avoid breaking the assumptions surrounding hooks. Just try accessing state in a
setTimeout
and you'll see what I mean.Svelte 4 had a few gotchas like this — for example, async code that interacts with a component's DOM elements has to keep track of whether the component is unmounted. This is pretty similar to the kind of pattern you'd see in old React components that relied on lifecycle methods.
It seems to me that Svelte 5 has gone the React 16 route by adding implicit state related to component lifecycles in order to coordinate state changes and effects.
For example, here is an excerpt from the documentation for $effect:
You can place $effect anywhere, not just at the top level of a component, as long as it is called during component initialization (or while a parent effect is active). It is then tied to the lifecycle of the component (or parent effect) and will therefore destroy itself when the component unmounts (or the parent effect is destroyed).
That's very complex! In order to use
$effect
... effectively (sorry), developers have to understand how state changes are tracked. The documentation for component lifecycles claims:In Svelte 5, the component lifecycle consists of only two parts: Its creation and its destruction. Everything in-between — when certain state is updated — is not related to the component as a whole; only the parts that need to react to the state change are notified. This is because under the hood the smallest unit of change is actually not a component, it’s the (render) effects that the component sets up upon component initialization. Consequently, there’s no such thing as a “before update”/"after update” hook.
But then goes on to introduce the idea of
tick
in conjunction with$effect.pre
. This section explains that "tick
returns a promise that resolves once any pending state changes have been applied, or in the next microtask if there are none."I'm sure there's some mental model that justifies this, but I don't think the claim that a component's lifecycle is only comprised of mount/unmount is really helpful when an addendum about state changes has to come right afterward.
The place where this really bit me, and which is the motivation for this blog post, is when state gets coupled to a component's lifecycle, even when the state is passed to another function that doesn't know anything about svelte.
In my application, I manage modal dialogs by storing the component I want to render alongside its props in a store and rendering it in the
layout.svelte
of my application. This store is also synchronized with browser history so that the back button works to close them. Sometimes, it's useful to pass a callback to one of these modals, binding caller-specific functionality to the child component:javascript const {value} = $props() const callback = () => console.log(value) const openModal = () => pushModal(MyModal, {callback})
This is a fundamental pattern in javascript. Passing a callback is just one of those things you do.
Unfortunately, if the above code lives in a modal dialog itself, the caller component gets unmounted before the callback gets called. In Svelte 4, this worked fine, but in Svelte 5
value
gets updated toundefined
when the component gets unmounted. Here's a minimal reproduction.This is only one example, but it seems clear to me that any prop that is closed over by a callback function that lives longer than its component will be undefined when I want to use it — with no reassignment existing in lexical scope. It seems that the reason this happens is that the props "belong" to the parent component, and are accessed via getters so that the parent can revoke access when it unmounts.
I don't know why this is necessary, but I assume there's a good engineering reason for it. The problem is, this just isn't how javascript works. Svelte is essentially attempting to re-invent garbage collection around component lifecycles, which breaks the assumption every javascript developer has that variables don't simply disappear without an explicit reassignment. It should be safe to pass stuff around and let the garbage collector do its job.
Conclusion
Easy things are nice, but as Rich Hickey says, easy things are not always simple. And like Joel Spolsky, I don't like being surprised. Svelte has always been full of magic, but with the latest release I think the cognitive overhead of reciting incantations has finally outweighed the power it confers.
My point in this post is not to dunk on the Svelte team. I know lots of people like Svelte 5 (and react hooks). The point I'm trying to make is that there is a tradeoff between doing things on the user's behalf, and giving the user agency. Good software is built on understanding, not cleverness.
I also think this is an important lesson to remember as AI-assisted coding becomes increasingly popular. Don't choose tools that alienate you from your work. Choose tools that leverage the wisdom you've already accumulated, and which help you to cultivate a deeper understanding of the discipline.
Thank you to Rich Harris and team for many years of pleasant development. I hope that (if you read this) it's not so full of inaccuracies as to be unhelpful as user feedback.

2025-02-17 06:06:48As promised in my last article:
nostr:naddr1qvzqqqr4gupzp394x6dfmvn69cduj7e9l2jgvtvle7n5w5rtrunjlr6tx6up9k7kqq2k6ernff9hw3tyd3y453rdtph5uvm6942kzuw08y0
In this one we will dive into how exactly an unidirectional payments channel powered ecash mint system would be implemented, using the tech available today! So if you haven't read that article yet, give it a read!
I first intended to write a longwinded article, explaining each part of the system. But then I realized that I would need some visualization to get the message across in a more digestable way. This lead me to create a slide deck, and as I started to design the slides it became more and more clear that the information is easier shown with visualizations, than written down. I will try to give a summary as best as I can in this article, but I urge you, to please go visit the slide deck too, for the best experience:
TAKE ME TO THE SLIDE DECK!
Intro
In this article we will go over how we can build unidirectional payment channels on Bitcoin. Then we will take a look into how Cashu ecash mints work, and how we can use unidirectional payment channels to change the dynamics between ecash users and the mint.
Before we start, let me also give credits to nostr:npub1htnhsay5dmq3r72tukdw72pduzfdcja0yylcajuvnc2uklkhxp8qnz3qac for comming up with the idea, to nostr:npub148jz5r9xujcjpqygk69yl4jqwjqmzgrqly26plktfjy8g4t7xaysj9xhgp for providing an idea for non-expiring unidirectional channels, and nostr:npub1yrnuj56rnen08zp2h9h7p74ghgjx6ma39spmpj6w9hzxywutevsst7k5cx unconference for hosting an event where these ideas could be discussed and flourish.
Building unidirectional payment channels
If you've read the previous article, you already know what unidirectional payment channels are. There are actually a coupple different ways to implement them, but they all do have a few things in common:
- The
sender
can only send - The
Receiver
can only receive - They are VERY simple
Way simpler than the duplex channels like we are using in the lightning network today, at least. Of course, duplex channels are being deployed on LN for a reason. They are very versatile and don't have these annoying limitations that the unidirectional payment channels have. They do however have a few drawbacks:
- Peers have liveness requirements (or they might forfeit their funds)
- Peers must backup their state after each transaction (if they don't they might forfeit their funds)
- It is a pretty complex system
This article is not meant to discredit duplex channels. I think they are great. I just also think that in some use-cases, their requirements are too high and the system too complex.
But anyway, let's see what kind of channels we can build!
Spillman/CLTV-Channel
The Spillman channel idea has been around for a long time. It's even explained in Tadge Dryjas Presentation on Payment channels and the lightning network from back in the day. I compiled a list of some of the most important propperties of them in the slide below:
Great!
Now that we know their properties, let's take a look at how we can create such a channel (Slides):
We start out by the
sender
creating afunding TX
. Thesender
doesn't broadcast the transaction though. If he does, he might get locked into a multisig with thereceiver
without an unilateral exit path.Instead the
sender
also creates arefund TX
spending the outputs of the yet unsignedfunding TX
. Therefund TX
is timelocked, and can only be broadcast after 1 month. Bothsender
andreceiver
can sign thisrefund TX
without any risks. Oncesender
receives the signedrefund TX
, he can broadcast thefunding TX
and open the channel. Thesender
can now update the channel state, by pre-signing update transactions and sending them over to thereceiver
. Being a one-way channel, this can be done in a single message. It is very simple. There is no need for invalidating old states, since thesender
does not hold any signedupdate TXs
it is impossible for thesender
to broadcast an old state. Thereceiver
only cares about the latest state anyways, since that is the state where he gets the most money. He can basically delete any old states. The only thing thereceiver
needs to make sure of, is broadcasting the latestupdate TX
before therefund TX's
timelock expires. Otherwise, thesender
might take the whole channel balance back to himself.This seems to be already a pretty useful construct, due to its simplicity. But we can make it even more simple!
This setup works basically the same way as the previous one, but instead of having a refund transaction, we build the
timelock
spend path directly into thefunding TX
This allows thesender
to have an unilateral exit right from the start, and he can broadcast thefunding TX
without communicating with thereceiver
. In the worst case, the receiver rejects the channel, and the sender can get his money back after the timelock on the output has expired. Everything else basically works in the same way as in the example above.The beauty about this channel construct is in its simplicity. The drawbacks are obvious, but they do offer some nice properties that might be useful in certain cases.
One of the major drawbacks of the
Spillman-style channels
(apart from being unidirectional) is that they expire. This expiry comes with the neat property that neither of the party has to watch the chain for channel closures, and thesender
can operate the channel with zero additional state, apart from his private keys. But they do expire. And this can make them quite inflexible. It might work in some contexts, but not so much in others, where time needs to be more flexible.This is where
Roose-Childs triggered channels
come into play.Roose-Childs triggered channel
(I gave it that name, named after nostr:npub148jz5r9xujcjpqygk69yl4jqwjqmzgrqly26plktfjy8g4t7xaysj9xhgp and nostr:npub1htnhsay5dmq3r72tukdw72pduzfdcja0yylcajuvnc2uklkhxp8qnz3qac . If someone knows if this idea has been around before under a different name, please let us know!)
Roose-Childs triggered channels
were an idea developed by Steven and Luke at the nostr:npub1yrnuj56rnen08zp2h9h7p74ghgjx6ma39spmpj6w9hzxywutevsst7k5cx unconference. They essentially remove the channel expiry limitation in return for introducing the need for thesender
to create a channel backup at the time of channel creation, and for thereceiver
the need to watch the chain for trigger transactions closing the channel.They also allow for splicing funds, which can be important for a channel without expiry, allowing the
sender
to top-up liquidity once it runs out, or for thereceiver
taking out liquidity from the channel to deploy the funds elsewhere.Now, let's see how we can build them!
The
funding TX
actually looks the same as in the first example, and similarly it gets created, but not signed by thesender
. Then, sender and receiver both sign thetrigger TX
. Thetrigger TX
is at the heart of this scheme. It allows bothsender
andreceiver
to unilaterally exit the channel by broadcasting it (more on that in a bit).Once the
trigger TX
is signed and returned to thesender
, the sender can confidently sign and boradcast thefunding TX
and open the channel. Thetrigger TX
remains off-chain though. Now, to update the channel, thesender
can pre-sign transactions in similar fashion to the examples above, but this time, spending the outputs of the unbroadcastedtrigger TX
. This way, both parties can exit the channel at any time. If thereceiver
wants to exit, he simply boradcasts thetrigger TX
and immediately spends its outputs using the latestupdate TX
. If thesender
wants to exit he will broadcast thetrigger TX
and basically force thereceivers
hand. Either, thereceiver
will broadcast the latestupdate TX
, or thesender
will be able to claim the entire channel balance after the timelock expired.We can also simplify the
receiver's
exit path, by thesender
pre-signing an additional transactionR exit TX
for each update. this way, thereceiver
only needs to broadcast one transaction instead of two.As we've mentioned before, there are some different trade-offs for
Roose-Childs triggered channels
. We introduce some minimal state and liveness requirements, but gain more flexibility.Ecash to fill in the gaps
(I will assume that the reader knows how ecash mints work. If not, please go check the slides where I go through an explanation)
Essentially, we are trying to get a lightning like experience, without all the lightning complexities and requirements. One big issue with ecash, is that it is fully custodial. If we can offset that risk by holding most of the funds in a self custodial channel, we can have a reasonable trade-off between usability and self custody.
In a system like that, we would essentially turn the banking model onto its head. Where in a traditional bank, the majority of the funds are held in the banks custody, and the user only withdraws into his custody what he needs to transact, in our model the user would hold most funds in his own custody.
If you ask me, this approach makes way more sense. Instead of a custodian, we have turned the "bank" into a service provider.
Let's take a look at how it would work in a more practical sense:
The
ecash user
would open an unidirectional payment channel to themint
, using one of his on-chain UTXOs. This allows him then to commit incrementally funds into the mints custody, only the amounts for his transactional needs. The mint offers connectivity to the lightning network an handles state and liveness as a service provider.The
ecash user
, can remain offline at all times, and his channel funds will always be safe. The mint can only ever claim the balance in the channel via theupdate TXs
. Themint
can of course still decide to no longer redeem any ecash, at which point they would have basically stolen theecash user's
transactional balance. At that point, it would probably be best for theecash user
to close his channel, and no longer interact or trust thismint
.Here are some of the most important points of this system summarized:
And that is basically it! I hope you enjoyed this breakdown of Unidirectional payment channel enabled Ecash mints!
If you did, consider leaving me a zap. Also do let me know if this type of breakdown helps you understand a new topic well. I am considering doing similar breakdowns on other systems, such as ARK, Lightning or Statechains, if there is a lot of interest, and it helps people, I'll do it!
Pleas also let me know what you think about the
unidirectional channel - ecash mint
idea in the comments. It's kind of a new idea, an it probably has flaws, or things that we haven't thought about yet. I'd love to discuss it with you!I'll leave you with this final slide:
Cheers,

2025-04-27 16:23:40Are you tired of having to trust banks and other financial institutions with your money? With Bitcoin, you can take control of your finances and be the sole custodian of your wealth. This is known as self-custody and it completely eliminates the need for third-party services, by receiving and storing your bitcoin securely in your own Bitcoin wallet. In this blog post, we will discuss what self-custody means, how it works, and the benefits and responsibilities associated with being in control of your own money.
What is Self-Custody?
Self-custody is simply the process of keeping your own private keys to your Bitcoin wallet, meaning you do not need a bank or any other third party to manage or access your Bitcoin funds; you are able to do all that yourself. This means that only you have full control over your money, allowing you to make transactions securely and safely without ever having to ask someone’s permission or worry about someone else mishandling or stealing it.
Who Is in Charge of My Bitcoin?
When using Bitcoin, you are in charge of your own Bitcoin wallet, which includes an unlimited amount of addresses that are used to receive Bitcoin, and a private key that is used to sign outbound transactions. The private key is literally the key to your Bitcoin wallet, as it can send Bitcoin to other addresses your don’t control. As such, it is imperative that it is kept safe and secure, accessible only by you. This is how ownership of Bitcoin is determined. If you share the private key to a wallet you control, you’re not the only one able to spend the Bitcoin inside the wallet anymore.
Benefits & Responsibilities
The most obvious benefit of self-custody is that no one else has control over your funds but you! That said, there are some important responsibilities that come with owning the keys to your Bitcoin wallet.
One responsibility that comes with being the only owner of your Bitcoin funds is making sure that your private key is safe from theft and loss. Fortunately, there are easy solutions available for securely storing Bitcoin keys, and seeking guidance from a knowledgeable source can be a great help if you’re not ready to take on this responsibility alone. A Bitcoin security expert can provide valuable insights and tools to help you ensure the safety and security of your funds.
Overall, Bitcoin gives immense power to individuals who want full control over their finances without relying on third parties like banks or payment processors. But taking ownership of your money also comes with certain responsibilities such as safeguarding your private keys; however these responsibilities pale in comparison when compared with the freedom and security granted by taking ownership of your money with Bitcoin! And with the right tools and guidance, using Bitcoin in a truly sovereign way can be way easier than you may imagine.

2025-02-16 08:39:59Almost 150 years ago, the British newspaper editor William Thomas Stead wrote that "the editorial pen is a sceptre of power, compared with which the sceptre of many a monarch is but a gilded lath". He had begun to regard journalism as something more than just conveying information - the journalist or editor could become a ruler.
Times had certainly changed compared to a few hundred years earlier. Before Gutenberg's invention of the printing press, it was mainly the church that controlled the dissemination of information in Europe, but when Stead put pen to paper, this control had shifted to newspapers, schools, and universities. Eventually, technologies like radio and TV entered the scene, but the power dynamics remained asymmetrical - only a few could send information to the many.
However, with the emergence of the internet, and especially with the spread of social media, a significant change followed. Instead of only a few being able to send information to the many, many could send to many. Almost anyone could now create their own newspaper, radio, or TV channel. The power over information dissemination was decentralised.
Ten years ago, Roberta Alenius, who was then press secretary for Sweden's Prime Minister Fredrik Reinfeldt of the Moderate Party, shared her experiences with Social Democratic and Moderate Party internet activists on social media. She reported that social media played a significant role in how news "comes out" and is shaped, and that journalism was now downstream of social media. Five years later, NATO's then-Secretary-General Jens Stoltenberg said that "NATO must be prepared for both conventional and hybrid threats: from tanks to tweets." This finally underscores the importance of social media.
Elon Musk, who took over X (formerly Twitter) in 2022, has claimed that "it's absolutely fundamental and transformative that the people actually get to decide the news and narrative and what's important," and that citizen journalism is the future.
While his platform allows most expressions - for better or worse - the reach of messages is instead limited ("freedom of speech does not mean freedom of reach "). X has also opened its recommendation algorithm to the outside world by making it open-source. Although this is a welcome step, the fact remains that it's impossible to know which code is actually used and what adjustments are made by humans or algorithms.
William Thomas Stead's "sceptre of power", which has wandered from the church to newspaper and TV editorial offices, and now to citizens according to Elon Musk, risks being transferred to algorithms' opaque methods?
Instead of talking about "toxic algorithms" and TikTok bans, like the so many do today, we should ask ourselves more fundamental questions. What happens when algorithms are no longer objective (how can they ever be?), but instead become tools for shaping our reality? Perhaps our greatest challenge today is not deciding who should govern the information landscape, but instead recognising that no one is up to the task - not even well-ventilated computers.

2025-04-27 16:17:19To the few elites who benefit from the modern banking system and the constant emission of currency, Bitcoin is a threat to their privileged position.
For traders, investors, and gamblers who are only interested in making a quick buck, Bitcoin is a new and volatile asset they can speculate on.
For individuals escaping tyranny or authoritarian regimes, Bitcoin is a way to move their wealth across borders and avoid it being seized by the government.
For people who live in inflation-ridden countries, Bitcoin is a way to protect their wealth against accelerating devaluation and avoid losing all their money to inflation.
For digital nomads, Bitcoin is a great way to easily earn money online, avoid paying high commission fees to payment processors (Paypal, Stripe, etc), and avoid high currency conversion fees while traveling.
As we can see, Bitcoin definitely is different things to different people. What we all agree on, though, is that Bitcoin is here to reject the status quo.
Bitcoin is the best tool out there for people who value individual freedom and seek more self-sovereignty to take control of their money, their lives, and their future.
What is Bitcoin to you?

2025-02-14 16:29:51Bitcoin’s Price and the Power Law: A Reflection of Energy and the Early Stages of Monetary Adoption Introduction Bitcoin’s price trajectory has long puzzled analysts, with its seemingly chaotic booms and busts. However, when examined through the lens of power laws, a pattern emerges—one that is fundamentally tied to Bitcoin’s energy-based production cost. This article argues that Bitcoin’s price has historically followed a power law because its underlying cost structure is dictated by mining, an energy-intensive process. However, this relationship will not persist indefinitely. I propose that as Bitcoin matures into a widely adopted monetary system, its price will decouple from mining production costs and instead oscillate in accordance with natural business cycles, much like traditional forms of money.
Bitcoin’s Price and the Power Law
Source and Credit: Giovanni Santostasi’s “The Bitcoin Power Law”
When Bitcoin’s price is plotted on a logarithmic scale against time, a strikingly straight-line trajectory appears, punctuated by cycles of rapid price expansion (bull markets) followed by severe corrections (bear markets). These perturbations correspond to Bitcoin’s well-known halving cycles, which occur approximately every four years and reduce the block reward paid to miners, effectively doubling the cost of production per Bitcoin. Historically, Bitcoin’s price has always returned to a fundamental minimum—one that closely aligns with the average cost of mining.
This observation suggests that Bitcoin’s power law price behavior is not arbitrary but rather a reflection of its fundamental energy constraints. As in many natural systems governed by power laws, energy dynamics play a central role. In Bitcoin’s case, the “base layer” of its valuation is determined by the energy and computational resources required for mining. This power law behavior is therefore a consequence of Bitcoin’s fundamental design: as block subsidies decrease and mining efficiency improves, the minimum sustainable price follows an upward trajectory dictated by production costs.
Bitcoin as an Energy-Based System
Power laws commonly emerge in natural systems involving energy constraints, from thermodynamics to biological ecosystems and planetary dynamics. Bitcoin, as an energy-based monetary system, exhibits similar characteristics. Mining requires significant electricity and computational power, and as the difficulty adjustment ensures a competitive equilibrium, the cost of mining a Bitcoin remains closely tied to its market value over the long run.
Unlike traditional fiat currencies, which are controlled by central banks and subject to arbitrary monetary expansion, Bitcoin’s supply schedule is immutable. Its economic foundation is rooted in proof of work, where value is derived from energy expenditure. This fundamental linkage between energy and price explains why Bitcoin’s valuation has adhered to a power law trajectory. It is an entropy engine, and follows physical laws related to energy and entropy.
However, this pattern is not a permanent feature of Bitcoin’s monetary future—it is, rather, an indication of Bitcoin’s early-stage monetization process.
The Transition from Mining-Based Pricing to a Business Cycle
A crucial implication of Bitcoin’s price following a power law dictated by mining costs is that it suggests Bitcoin has yet to fully mature as money. If Bitcoin were already a widely adopted monetary standard, its valuation would no longer be primarily influenced by the floor mining costs but instead by macroeconomic forces—specifically, the natural fluctuations of the business cycle.
In a world where Bitcoin is the dominant global currency, the “price of money” (which correlates with the cost of capital and prevailing interest rates) would fluctuate according to the broader economic cycle. The dynamics would resemble those of natural interest rate cycles described by the Austrian School of Economics:
- During periods of economic expansion, lower interest rates spur increased investment and consumption, prices slightly rise, and savings deplete.
- As savings decline and prices rise, interest rates naturally rise as well, leading to reduced investment and spending, initiating a contractionary phase and lowered prices.
- During the contraction, savings accumulate, more capital becomes available, and interest rates and prices decline.
- With the availability of capital, lower interest rates and lowered prices, the economy is now ready to enter a phase of investment and expansion once again.
- This oscillatory process continues indefinitely, driven by real economic growth rather than central bank intervention.
If Bitcoin were fully monetized, its price would no longer oscillate based on mining halvings and energy costs but instead reflect economic expansion and contraction cycles—just as traditional currencies do when not artificially manipulated by central banks.
The Early Stage Indicator: Bitcoin’s Dependence on Mining Costs
Today, Bitcoin’s price still “bounces” off the power law baseline, indicating that its valuation remains primarily anchored to its minimum cost of production. This means that, while Bitcoin is widely recognized as an asset, it has not yet reached the level of adoption where its price is dictated by macroeconomic cycles.
A future in which Bitcoin is used as a primary medium of exchange and unit of account would necessarily imply a decoupling from mining-driven pricing. Instead of periodic halvings triggering speculative bull runs followed by crashes, Bitcoin’s price would become far more stable, with fluctuations primarily driven by business cycle dynamics. The continued adherence to the power law model, therefore, is evidence that Bitcoin is still in an early phase of adoption—where mining remains a primary determinant of price.
Conclusion
Bitcoin’s price trajectory has long conformed to a power law, reflecting the underlying energy costs of mining. This characteristic, however, is likely not a permanent feature but rather a hallmark of Bitcoin’s early stage as an emerging monetary system. As adoption increases and Bitcoin becomes widely used as money, its price should transition away from being dictated by mining costs and should instead fluctuate according to the natural oscillations of the business cycle.
The persistence of Bitcoin’s power law trend is a sign that it remains in its infancy. The real transformation will occur when Bitcoin is no longer bound to its production cost but is instead driven by the natural ebb and flow of savings, investment, and capital cycles—marking its full emergence as a global monetary system.

2025-04-27 12:27:37Ach Gottchen, man ist mal wieder empört! Quel fauxpas! Ist es nicht auffällig, dass man von anderen Nationen solche Bilder nicht sieht? Zwei Politiker im Flieger unterwegs zu einer Vergnügens-Beerdigung eines Mannes, der für eine nicht geringe Anzahl von Menschen auf der Erde eine sehr große Bedeutung hat. (Impfen ist Nächstenliebe und die Kündigung derjenigen, die sich der Gen-Behandlung nicht unterziehen wollten, hier einmal außen vor gelassen). Warum ausgerechnet immer die Deutschen? Tja, anscheinend hat Deutschland den Joker im ins-Fettnäpfchen-treten gepachtet und gibt ihn nicht mehr aus der Hand. Meister aller Klassen bleibt bisher noch die feministische Außen-Dings, aber was nicht ist, kann ja noch werden. Und ausgerechnet ein Herr Laschet muss auch seinen Senf dazu geben, obwohl man doch eigentlich nicht mit Steinen wirft, wenn man im Glashaus sitzt. Unvergessen seine heitere Stimmung bei einem Besuch im verwüsteten Ahrtal, das bis heute noch teilweise nicht wiederhergestellt ist.
Herrn Steinmeier ist kein Vorwurf zu machen. Schließlich repräsentiert er mit einer florierenden Wirtschaft, einem vom Stier getriebenen Vielleicht-Bundeskanzler, einem Noch-Gesundheitsminister mit Traumjob, der gerne weiter gemacht hätte (auch die guten Kräfte haben ihre Grenzen des Ertragbaren), das Land des Lächelns.
Bei der Gelegenheit: Herr Lauterbach erinnert doch sehr an die Gräfin Eleonora Moran aus „Die Seltsame Gräfin“ von Edgar Wallace. In dem Film gibt es eine Szene, in der sie sagt: „Ich bin eine Wohltäterin der Menschheit, ich habe immer nur Gutes getan, niemals etwas Böses! Fassen Sie mich nicht an! Ich bin die Gräfin Eleonora Moran!“
Und Herr Söder, was soll man dazu sagen. Der bayerische Möchtegern-König, der sein Fähnchen schneller nach dem Wind dreht, als der Wind selbst es kann.
Und Herr Merz war wohl leider verhindert. Der belegte über Ostern einen Kurs bei der Volkshochschule: Torero werden in drei Wochen! Nach diesem Kurs werden Sie mit jedem Stier spielend fertig!
Fair bleiben: Gespielte Betroffenheit wäre geheuchelt gewesen. Schließlich besteht keine nahe Verwandtschaft zwischen Steinmeier und Söder zu dem Petrus-Nachfolger.
Am Ende ist es eine Pflichtveranstaltung, wie der Besuch bei der unangenehmen Erbtante, zu dem man eigentlich gar keine Lust hat, aber man muss halt, weil die Taler locken.
Schade, dass Herr Pistorius nicht auch mit im Malle-Flieger dabei war und auf dem Selfie. Dann hätte man einen schönen Untertitel gehabt: Na, ihr da unten auf dem Boden. Seid ihr auch alle schön kriegstüchtig?
Und dann gibt es da noch das Bild von Trump und Selensky in einer großen Halle im Vatikan, zwei Stühle, reduziert auf das Wesentliche: Keine Gelegenheit auslassen miteinander zu reden, den Frieden in der Ukraine besser gestern als heute herbeizuholen. Das macht den Ernst der Lage sehr deutlich. Für Macron war wohl im ganzen Vatikan kein weiterer Stuhl aufzutreiben. Deutsche Politiker glänzten durch Abwesenheit. War vielleicht auch gut so. Da stand vermutlich auch zerbrechliches Porzellan im Raum.
Im Gegensatz dazu das Bild der beiden Grinsekater, das wohl um die halbe Welt gehen wird. Was für eine Blamage. Man könnte fast meinen, da steckt Absicht dahinter. Die Absicht, Deutschland unter allen Umständen in die vollkommene Lächerlichkeit überführen zu wollen. Über Rom lacht die Sonne, über Deutschland die ganze Welt. Kann nicht Herr Brabeck-Letmathe vom WEF mal was Erhellendes dem deutschen Trinkwasser beimischen, damit die Politiker wieder zur Vernunft kommen?
Was würde Äarwin Krawuttke aus Wanne-Eickel wohl dazu sagen: Ey, voll der Schuss in den Ofen! Datt wollen Pollitiker sein? Ich lach mich kaputt!

2025-04-27 10:11:09更新前有问题问题?
本站采用 docsify渲染,他对图片的处理 是没有任何类原始的 img标签。 缺点如下: * 图片太大,很多图片出现了锯齿; * 图片和周边的文字没有边界,非常突兀;
第一次修改
全加了统一风格,用圆角修饰了;
结果出现了新问题,有些小图片是一个图标,例如:github 的star变得异常难看。
怎么办?
第二次修改
查找 文档说 markdown文档有支持{.classname}的做法,有人用这个方法;
那么 docsify如何做的呢?
js window.$docsify = { name: title, loadSidebar: true, homepage: "readme.md", subMaxLevel:2, plugins: [imgClassPlugin], alias: { '/_sidebar.md': './_sidebar.md', } };
用plugins 就可以,
imgClassPlugin 是找的正则替换
`` js export function processMarkdownImages(content) { const regex = /!\[(.*?)\]\((.*?)\)(\{.*?\})?/g; return content.replace(regex, (match, alt, src, classInfo) => { if (classInfo) { const classNames = classInfo.match(/\.([a-zA-Z0-9_-]+)/); if (classNames) { const className = classNames[1]; return
`; } } return match; }); }
// 定义 Docsify 插件 export const imgClassPlugin = function (hook, vm) { hook.mounted(function () { // 在文档挂载后,在每次渲染前执行处理逻辑 hook.beforeEach(function (content) { return processMarkdownImages(content); }); }); };
``` 这样就可以了。大家看看我这张图片:
{.user-img}
具体用法,大家参考 https://www.nostrbook.com/books/c3834c0604b4e5ad66ececd756791a539c585d880864d62b0ef51e3602c482b7?title=NostrBook%E7%AB%99%E7%82%B9%E6%97%A5%E8%AE%B0#/02

2025-02-14 09:44:55I asked unleashed.chat's DeepSeek model to provide the pieces of evidence against the moon landing. What follows is what I got as my answer.
Generally, I like the answer, though it mixed up the claim and counterarguments at times.
Also, I didn't like the conclusion :))
But all said, I believe the Van Allen Belts are one of the most solid argument against the moon landing.
The question of whether the moon landing was faked has been a topic of debate, with various arguments presented by those who doubt the authenticity of the event. Here is a summary of the key points often cited against the moon landing, along with counterarguments and explanations:
Arguments Against the Moon Landing: Waving Flag:
Claim: The American flag appears to wave in the wind, despite the moon having no atmosphere. Counterargument: The flag's movement was caused by the astronauts' actions, as they adjusted it using a rod behind the flag. Missing Stars:
Claim: The photos lack visible stars, which should be present in the moon's black sky. Counterargument: The cameras were set for optimal lighting of the lunar surface, making stars too faint to capture. Shadow Anomalies:
Claim: Shadows in photos appear to come from multiple directions, suggesting studio lighting. Counterargument: The moon's surface is uneven, causing shadows to appear differently, and the sun's angle can create varied shadows. Van Allen Belts:
Claim: Astronauts would have been exposed to lethal radiation from the Van Allen belts. Counterargument: The missions were timed to pass through the belts quickly, minimizing exposure. Lack of Blast Crater:
Claim: No noticeable crater was created by the lunar module's descent engine. Counterargument: The engine's thrust was designed to minimize impact, and the moon's surface is softer than expected. Missing Footage:
Claim: Original tapes of the landing were lost, and restored footage is of lower quality. Counterargument: Footage was restored from other sources, including TV broadcasts and telemetry data. Soviet Silence:
Claim: The Soviets did not contest the landing, despite being space race competitors. Counterargument: The Soviets may not have had the means to verify the landing or were focused on their own programs. Technological Capabilities:
Claim: The technology of the 1960s was insufficient for a moon landing. Counterargument: Successful unmanned missions and technological advancements supported the capability. Number of Participants:
Claim: Thousands of people involved would have leaked the secret. Counterargument: Secrecy measures and unawareness of implications could have prevented leaks. "C" Rock Incident:
Claim: A rock appeared to float, suggesting tampering. Counterargument: The rock was a prop, and movement was due to low-gravity actions. Supporting Evidence for the Moon Landing: Moon Rocks: Analyzed and confirmed as lunar. Footprints and Equipment: Observed by subsequent missions and satellites. Cumulative Evidence: Multiple sources confirm the moon landing. In conclusion, while various arguments have been presented against the moon landing, each has been addressed with scientific explanations and evidence. The consensus among the scientific community is that the moon landing was genuine, supported by substantial evidence and corroborated by multiple sources.

2025-02-12 16:57:44Micropayments on the Internet have been theorized for decades. However, it wasn’t until the emergence of Nostr that we’ve finally seen them deployed at scale. Nostr is still in its infancy, yet we are already witnessing an explosion of apps built on top of this open protocol. And most of them are featuring zaps! With the recent Primal 2.1 release, Nostr developers now have the option to enhance the experience for their users by integrating a Nostr-powered bitcoin wallet.
There is no doubt that micropayments add a new dimension to consumer apps. The incumbents have realized this and are rushing to add payments to their closed platforms. It won't be long before apps that don’t include built-in payments feel dated or outright broken. The question is not if apps of the future will have built-in payments, but what kind of payments they will be. Given that open networks have a tendency to win, our bet is that apps of the future will be powered by Bitcoin. Let’s see how Primal can help.
Primal Wallet
Our vision for Primal Wallet is simple: deliver the smoothest transactional bitcoin wallet, endowed with expert Nostr skills. The wallet leverages Nostr’s open social graph as a de facto public lightning directory, while offering the highest level of user experience for Nostr’s rich content. For example, the user can scroll through the transaction list, select a zap, and drill straight into the conversation thread where the zap originated. The whole flow feels perfectly natural.
Since we launched Primal Wallet in December 2023, the user response has been incredibly positive. People love the idea of being able to post something on Nostr, get zaps from plebs around the world, then buy a coffee or a meal with those sats - all from the same app.
Having a bitcoin wallet with social skills resonated strongly with users, so Primal Wallet grew rapidly in popularity and usage. Since the launch, we have processed 1,338,460 transactions, with 238,916 just in the past month alone. This rivals some of the leading bitcoin wallets, and we are just getting started! We hear from many bitcoin OGs that they are using Primal Wallet as their transactional daily driver. Bullish.
All this is great, but something has been missing. Our users demanded the ability to connect Primal Wallet to other Nostr apps, so they can zap from anywhere in Nostr’s growing ecosystem.
Zapping from Any Nostr App
For an existing Primal user, connecting the wallet to a new Nostr app can now be done in two clicks. Let’s take a look at how this is done from Olas, one of the most exciting new apps on Nostr:
Yes. Click, click. And you can start zapping!
Such smooth integration of payments is not available in any competing technology stack. Tradfi, fintech, crypto, etc., have nothing on Bitcoin and Nostr. Two clicks and your external wallet is connected. I’ll give you a moment now to allow for this new reality to settle in.
Primal enables you to connect any number of external apps and manage them from wallet settings:
Note that you can set your daily spend budget for each app or revoke its access at any time.
How This Works
So, what is this sorcery? How does it work under the hood?
Connecting Nostr apps to external wallets is accomplished via the Nostr Wallet Connect protocol. It utilizes Nostr’s public relay infrastructure to enable communication between apps and wallets. You can learn more about this protocol here, and access developer docs here.
The smooth, two-click connection setup UX is implemented through deep links between Primal and the external app. Here’s the deep link that the external app needs to call to invoke this feature:
nostrnwc+primal://connect?appicon=[icon_url]&appname=[app_name]&callback=[callback_string]
After the user clicks “Create Wallet Connection” in Primal, the Primal app calls the deep link defined in the callback, and passes the NWC connection string. That's all that the external app needs to make the wallet connection.
What Comes Next?
The Nostr Wallet Connect protocol has been around for almost two years. Several bitcoin wallets implement it and many Nostr apps use it as their main way of enabling payments. What’s new with Primal 2.1 is the elevated user experience. Since Primal is a Nostr-powered wallet, it is aware of all the relevant metadata for each transaction: Nostr zaps, users, and the related events. Primal indexes the entire Nostr network, and now this is open to all Nostr apps that wish to integrate payments.
Nostr keeps expanding and getting better. Its openness enables us to build capabilities that lift all boats. The future is bright; I can’t wait to see how things evolve from here. 🍿🍿🍿

2025-02-12 12:23:40Unidirectional payment channels revisited
Nodeless lightning - Reduce ecash mints custodial risk
Sats N Facts
The nostr:npub1yrnuj56rnen08zp2h9h7p74ghgjx6ma39spmpj6w9hzxywutevsst7k5cx unconference has just wrapped up. And what a blast it was. In the heart of northern Thailand, developers, researchers, content creators and more, came together to share ideas on how Bitcoin, Nostr and other free protocols are being used everyday to liberate people.
Not only were stories shared from different community leaders on how embracing bitcoin has empowered them and their communities, but a big goal of the unconference was to bring bitcoin engineers and developers from various domains together in one room, unstructured, chaotic, and let them do their thing.
At first, I thought not having a schedule might be boring, but oh boy was I wrong. There was so much stuff going on, it was hard to choose which session I would have to miss!
Luke's Spillman channel proposal
One of the sessions I definitely did not want to miss, was nostr:npub1htnhsay5dmq3r72tukdw72pduzfdcja0yylcajuvnc2uklkhxp8qnz3qac s proposal
Ecash mints funded with Spillman channels: The ultimate nodeless Lightning wallet
.
In true unconference fashion, he announced in the main room that the session was about to start, and that the people that are interested should meet him in the whiteboard corner in 10 minutes. The corner was packed, and Luke explained his proposal.
What's a "Spillman channel"?
Essentially when we are talking about Spillman channels, what is meant are unidirectional payment channels (or CLTV-style channels). An unidirectional payment channel means, only one party can send payments, but not receive, and the other party can only receive, but not send. They also expire after a predetermined amount of time, and must be closed.
At first glance, this might look kinda stupid. After all, we have Poon-Dryja channels that are powering the lightning network. They are bi-directional, do not expire, and can be used to shuffle coins back and forth theorethically an unlimited amount of times.
So, why bother with this stupid one-way channel?
Simplicity is king
People that have worked with lightning channels can sing you a song about complexity, state handling and risks about the current state of bidirectional payment channels. Essentially, There are a lot of requirements on both channel parties when it comes to Liveness (being online) and also state handling (continuous backups).
In some cases, especially when in the context of end-users wanting to perform payments on their mobile phone, they would appreciate it if there was not so much complexity and overhead involved.
The gist of the idea is to combine unidirectional channels and ecash mints to achieve the following:
A self custodial unidirectional payment channel to an ecash mint, massively reducing the senders liveness and state handling requirements when compared to a lightning channel. Sending payments through the mint will be done through swapping some of the channel balance for ecash tokens. At this point, the user is trusting the mint to honor the redemption of these tokens, while the remaining channel balance remains in self custody. This gives them better controll over their funds than just holding their entire balance custodied in the mint. The ecash tokens can then be redeemed to pay a lightning invoice, just the same as it is done now with normal cashu mints.
So this channel, that has no liveness or state management requirements for the sender, and must have a pre-defined close time, seems to be a perfect fit for the following usecase:
- A
sender
receives his salary once a month. He opens a channel that is valid for one month. - The
sender
then can do his daily spending over this channel. He only trusts themint
with the amount for the current outgoing payment while it is swapped for ecash, waiting for redemption. - If the
sender
must receive funds (a refund for example), he can do so into themints
custody, by receiving ecash. He can spend his ecash funds first when doing his next payment, to reduce his custodial exposure. - When the channel expires, or runs out of funds, the
mint
closes the channel.
From a consumer perspective, that just want to receive his salary and make frequent payments afterwards, this usecase seems to make a lot of sense. Obviously from a merchants perspective on the other hand, such a channel doesn't really work. But that's fine, it's not the problem we're trying to solve here.
What do you think of this idea? Be sure to let me know in the comments!
In the next article, we will dive into how such a system can be implemented today, using Bitcoin, Cashu and Lightning. We will also discover how the system can be improved, to make channels non-expiring (A collaborative idea between nostr:npub148jz5r9xujcjpqygk69yl4jqwjqmzgrqly26plktfjy8g4t7xaysj9xhgp and nostr:npub1htnhsay5dmq3r72tukdw72pduzfdcja0yylcajuvnc2uklkhxp8qnz3qac born at nostr:npub1yrnuj56rnen08zp2h9h7p74ghgjx6ma39spmpj6w9hzxywutevsst7k5cx ).

2025-02-09 00:16:551. What if You Could Send a Message into the Future?
Imagine leaving a message for your future self, a loved one, or even an entire community—one that no one, not even you, can unlock until a specific moment in time. Picture leaving a message for your children, a note of wisdom or love that remains hidden until they're old enough to appreciate it, all timed by Bitcoin's block height. You might also make a bold prediction about the future price of Bitcoin, sealing it away until the blockchain reaches a certain block height.
This is the idea behind Hatchstr, a decentralized app for time-locked messages that only unlock at predetermined Bitcoin block heights—no central authority required.
Why Build This?
I want to dive into the Nostr protocol not just by reading documentation, but by actually building something that embodies its core principles: censorship resistance, user ownership, and decentralization. Hatchstr is both an experiment and a contribution to the Nostr ecosystem—a way to test the limits of permissionless communication while learning and engaging with the community.
2. The Vision: How Hatchstr Would Work for Users
At its core, Hatchstr lets users create time capsules—encrypted messages that only become readable after a specified Bitcoin block height. Here’s what that looks like:
- You design a capsule with text and images using Hatchstr’s web app.
- You pick an unlock time (e.g., 1000 blocks from now).
- The message is encrypted, locked away, and published as a Nostr event.
- At the chosen time, the decryption key is revealed, allowing the recipient to finally access the message.
Potential Use Cases
-
Personal Messages: Send birthday wishes that unlock at midnight, time-delayed love letters, or notes to your future self.
-
Timed Learning: Lock educational content to unlock when students reach key learning stages or ages.
-
Creative Storytelling: Release serialized fiction, riddles, or treasure hunt clues that unlock over time.
-
Community & Events: Time-gate announcements for Nostr-based communities or scheduled voting mechanisms.
3. The Centralized Trap: Why Build on Nostr
When thinking about how to implement this, we could go the obvious, easy route:
- Store messages on a centralized server.
- Release them when the time is right.
- Let users download their messages.
Simple, right? But is it the right approach? Let's break it down.
Why This Fails
-
Single Point of Failure: If my server goes down, all messages are unavailable.
-
Privacy Risks: Users would need to trust me not to access their messages.
-
Ownership & Longevity: What happens if I lose interest? The system dies with me.
A centralized model defeats the purpose of time-locking messages. Users shouldn’t have to trust a third party. We need decentralization.
4. Nostr to the Rescue: How Decentralization Can Help
Instead of a single server holding messages hostage, Nostr allows users to publish messages to decentralized relays. Here are the key differences:
-
Nostr IDs = Self-Owned Identities: Your public key is your identity, not tied to any company.
-
Relays = Decentralized Bulletin Boards: Anyone can run one, ensuring redundancy and censorship resistance.
-
Messages = Signed Events: Cryptographically signed by the sender or encrypted for only the recipient.
How Nostr Reduces Centralization
In this version of Hatchstr, capsules are still stored in a centralized manner at first until they 'hatch'. However, once the Bitcoin block height condition is met:
- Capsule Publication: The system publishes the capsule events to Nostr relays, making the messages available for decryption by the intended recipients.
This approach, while not eliminating the central server, allows for:
-
Third-Party Clients: Developers can now create clients that interact with Hatchstr capsules on Nostr, enhancing the system's openness and potentially leading to a richer ecosystem around time-locked messages.
-
Decentralized Access: Even though the initial storage is centralized, the access to the messages becomes decentralized once published to Nostr, reducing the dependency on a single point for message retrieval.
We have some improvements, but I am sure we can do better!
5. The Path to Decentralized Timekeeping
The Timeless Nature of Encryption
Encrypted messages exist outside time—once locked, they remain secure indefinitely. Modern cryptography (like AES-256) doesn’t "expire" or weaken unless decrypted (excluding brute force attacks). This creates a paradox: How do you bind something timeless to a specific moment in the physical world?
The Time-Lock Puzzle Dilemma
Cryptographers have proposed time-lock puzzles—encryption that requires sustained computation to unlock, theoretically forcing a minimum wait time. But these face critical hurdles:
-
Hardware Uncertainty
Solving time depends on an attacker’s computational power. A nation-state could crack in hours what takes years for a regular user. -
No Real-World Alignment
Puzzles can’t guarantee unlocks align with calendar dates or real-world events ("unlock on my child’s 18th birthday"). -
Energy Waste
Requires continuous computation, making it environmentally impractical for longer time locking.
Bitcoin as a Decentralized Clock
This is where Bitcoin’s blockchain shines. Its difficulty-adjusted proof-of-work acts as a trustless metronome:
-
Predictable Rhythm
Despite hash rate fluctuations, the 10-minute block target (via difficulty adjustments) creates a consistent approximation of real-world time.
-
Immutable History
Block height 1,000,000 will always correspond to the same point in Bitcoin’s timeline, regardless of future changes in mining power
Splitting the Problem
Hatchstr can bridge timeless encryption and blockchain timing by separating concerns:
1. Capsules – The time-locked message itself:
-
Design independent of the time-locking mechanism.
-
Encrypted client-side.
-
Content stored anywhere the user wants (IPFS, personal servers, etc.).
-
Completely owned by the user—not Hatchstr.
2. Clock Servers – Independent, lightweight timing nodes that:
-
Only publish decryption keys when the target Bitcoin block height is reached.
-
Users can choose which Clock Server to trust.
-
Anyone can run their own Clock Server.
-
Multiple servers can coordinate to prevent a single point of failure.
This means Hatchstr itself doesn’t store anything—users are fully in control.
6. What Comes Next
This project is just beginning—a blueprint with open questions and untested assumptions. In the next two articles, I’ll explore how to turn this concept into something tangible. First, how we might design playful time capsules that can be displayed faithfully by multiple clients, balancing creativity with decentralization. Then, the messy realities of clock servers: why federating them matters, how to incentivize reliability, and borrow Bitcoin’s rhythm without centralizing control. We will dive into setting up a simple clock server to get things started.
I’m still learning Nostr’s ecosystem, and this project is as much about sharing my education as anything else. If any part of this concept makes you think “yes, but…” or “what if…”, I’d genuinely love to hear it. Find me on Nostr – no expertise required, just an interest in sending messages to the future. :
