2025-05-30 01:14:10ย้อนกลับไปปี 2014 ชายชื่อ Patrick O. Brown ศาสตราจารย์ชีววิทยาเชิงโมเลกุลแห่งมหาวิทยาลัยแตนฟอร์ด ตัดสินใจลาออกจากเส้นทางวิชาการสายหลัก เพื่อมาก่อตั้งบริษัทที่เขาเชื่อว่าจะเปลี่ยนโลก Impossible Foods
ดร. แพทริค โอ. บราวน์ (Patrick O. Brown) เป็นนักชีวเคมีและนักธุรกิจชาวอเมริกันและศาสตราจารย์กิตติคุณด้านชีวเคมีแห่งมหาวิทยาลัยสแตนฟอร์ด เขาได้รับปริญญาตรี แพทยศาสตรบัณฑิต และปรัชญาดุษฎีบัณฑิตด้านชีวเคมีจากมหาวิทยาลัยชิคาโก หลังจากนั้น เขาได้เข้ารับการฝึกอบรมด้านกุมารเวชศาสตร์ที่โรงพยาบาล Children's Memorial ในชิคาโก ในช่วงหลังปริญญาเอก เขาได้ทำงานวิจัยเกี่ยวกับกลไกที่ไวรัส HIV และเรโทรไวรัสอื่น ๆ แทรกยีนของพวกมันเข้าสู่จีโนมของเซลล์ที่ติดเชื้อ ซึ่งช่วยนำไปสู่การพัฒนายาใหม่ในการต่อสู้กับโรคนี้
ในช่วงต้นทศวรรษ 1990 ดร. บราวน์และทีมงานของเขาที่สแตนฟอร์ดได้พัฒนาเทคโนโลยี DNA microarray ซึ่งเป็นเครื่องมือที่ช่วยให้นักวิจัยสามารถวิเคราะห์การแสดงออกของยีนทั้งหมดในจีโนมได้พร้อมกัน เทคโนโลยีนี้มีบทบาทสำคัญในการวิจัยทางชีววิทยาและการแพทย์ โดยเฉพาะในการจำแนกประเภทของมะเร็งและการพยากรณ์โรค
นอกจากนี้ ดร. บราวน์ยังเป็นผู้ร่วมก่อตั้ง Public Library of Science (PLOS) ซึ่งเป็นองค์กรไม่แสวงหาผลกำไรที่มุ่งเน้นการเผยแพร่ผลงานวิจัยทางวิทยาศาสตร์ให้เข้าถึงได้ฟรีและเปิดกว้างต่อสาธารณะ
ในปี 2011 ดร. บราวน์ได้ก่อตั้ง Impossible Foods โดยมีเป้าหมายในการสร้างผลิตภัณฑ์เนื้อสัตว์จากพืชที่มีรสชาติและเนื้อสัมผัสคล้ายเนื้อสัตว์จริง เพื่อลดผลกระทบต่อสิ่งแวดล้อมจากการเลี้ยงสัตว์ เขาและทีมงานได้ค้นพบว่าโมเลกุล heme ซึ่งเป็นส่วนประกอบที่ให้รสชาติและกลิ่นเฉพาะของเนื้อสัตว์ สามารถผลิตจากพืชได้ โดยเฉพาะจากรากถั่วเหลือง พวกเขาใช้เทคนิคทางวิศวกรรมชีวภาพในการผลิต heme จากยีสต์ที่ได้รับการดัดแปลงพันธุกรรม และนำมาผสมกับโปรตีนจากพืชเพื่อสร้างผลิตภัณฑ์ที่มีลักษณะคล้ายเนื้อสัตว์
ดร. บราวน์ได้รับการยอมรับอย่างกว้างขวางในวงการวิทยาศาสตร์และเทคโนโลยี โดยได้รับรางวัลและเกียรติคุณหลายรายการ รวมถึงการเป็นสมาชิกของ National Academy of Sciences และ National Academy of Medicine ของสหรัฐอเมริกา ด้วยความมุ่งมั่นในการแก้ไขปัญหาสิ่งแวดล้อมผ่านนวัตกรรมทางอาหาร ดร. แพทริค โอ. บราวน์ ได้กลายเป็นบุคคลสำคัญที่มีบทบาทในการเปลี่ยนแปลงวิธีการบริโภคอาหารของโลกในศตวรรษที่ 21
เป้าหมายของเขาไม่ใช่เพียงแค่ทำอาหาร แต่คือ "ยุติการทำปศุสัตว์ให้หมดสิ้นภายในปี 2035"
เขาไม่ได้พูดลอย ๆ เขาลงมือ “ทำเนื้อจากพืช” ด้วยเทคโนโลยีที่ซับซ้อนระดับวิศวกรรมชีวภาพ นำโปรตีนจากถั่วเหลือง + น้ำมันมะพร้าว + เทคเจอร์ + สารเติมแต่งอีกชุดใหญ่ มาผ่านกระบวนการแปรรูปจนดูคล้ายเนื้อย่าง แต่ที่ทำให้ “มันดูเหมือนเนื้อจริง” คือการเติม ฮีม (Heme) เข้าไปสารประกอบที่อยู่ในเลือดและเนื้อสัตว์จริง ๆ
Impossible Foods คือบริษัทที่ไม่ได้เพียง “ปลอมรสชาติเนื้อ” แต่พยายามสร้างเนื้อจากพืช ให้เหมือนเนื้อจริงที่สุดเท่าที่วิทยาศาสตร์จะเอื้อมถึง จุดขายที่ทำให้แบรนด์นี้ดังเปรี้ยงก็คือสิ่งที่เรียกว่า “ฮีม” (heme) หรือโมเลกุลเหล็กในเลือด ซึ่งเป็นตัวการหลักที่ทำให้เนื้อวัวมีกลิ่นและรสเฉพาะตัวเวลาถูกย่างจนหอมฉุย
ดร.แพทริค บราวน์ และทีมนักวิจัยของเขาเริ่มจากการค้นหาว่า “อะไรในพืช” ให้กลิ่นคล้ายเลือด พวกเขาพบว่า “Leghemoglobin” ซึ่งอยู่ในรากถั่วเหลือง มีโครงสร้างใกล้เคียงกับ Hemoglobin ในเลือดสัตว์มากที่สุด จุดพลิกของเทคโนโลยีนี้คือ การผลิตเลกฮีโมโกลบินจากพืชจำนวนมาก ทำไม่ได้โดยการถอนรากถั่วมาทุบคั้น แต่ต้องอาศัยวิศวกรรมชีวภาพขั้นสูง
พวกเขาจึงใช้กระบวนการที่เรียกว่า “fermentation by genetically modified yeast” หรือการหมักโดยยีสต์ที่ผ่านการดัดแปลงพันธุกรรม โดยนำยีนของพืชที่สร้าง leghemoglobin ไปใส่ในยีสต์ (Pichia pastoris) แล้วเลี้ยงยีสต์นั้นในถังหมักขนาดใหญ่แบบเดียวกับโรงเบียร์ พอยีสต์ขยายตัว มันจะผลิตเลกฮีโมโกลบินออกมาจำนวนมาก จากนั้นจึงสกัดออกมาผสมกับโปรตีนจากพืช เช่น โปรตีนจากถั่วเหลือง หรือโปรตีนจากมันฝรั่ง
เพื่อให้เนื้อสัมผัสคล้ายเนื้อจริง ทีม Impossible Foods ยังใช้เทคนิคอื่นร่วมด้วย เช่น -Coconut Oil และ Sunflower Oil เป็นแหล่งไขมันที่ให้สัมผัส “ฉ่ำๆ” คล้ายไขมันเนื้อวัว -Methylcellulose สารที่ช่วยทำให้ส่วนผสมเกาะตัวเป็นก้อน คล้ายเนื้อบดจริง -Natural Flavors กลิ่นที่สกัดจากพืชหลายชนิด เพื่อเลียนแบบกลิ่นไหม้จากเนื้อย่าง
ทุกอย่างถูกผสมให้เข้ากัน ผ่านเครื่องอัดขึ้นรูป (extrusion) ที่ทำให้เนื้อออกมามี “เส้นใย” คล้ายกล้ามเนื้อวัว หรือหมู เมื่อโดนความร้อน โปรตีนจะเปลี่ยนโครงสร้าง (denature) และมีกลิ่นออกมาคล้ายๆ เนื้อย่างจริงๆ พร้อมน้ำสีแดงคล้ายเลือด (จาก heme) ไหลเยิ้ม ซึ่งคือไอเดียที่ทำให้ Impossible Burger เป็นมากกว่าแค่ “เบอร์เกอร์ผัก”
ผลลัพธ์คือ… เบอร์เกอร์พืชที่มีเลือดซึม สีชมพูดู juicy และกลิ่นไหม้ติดกระทะ จนคนกินรู้สึกเหมือนกำลังย่างเนื้อจริง ๆ
ฟังดูอัศจรรย์ใช่ไหม? แต่...การเติมฮีมจากยีสต์ตัดต่อพันธุกรรมลงในอาหาร ไม่เคยมีในธรรมชาติมาก่อน ในปี 2017 Impossible Foods ต้องยื่นเรื่องต่อ FDA เพื่อขออนุมัติว่า leghemoglobin จากยีสต์ GMO “ปลอดภัย”
แต่ในตอนนั้น FDA ตอบว่า “ยังไม่มีข้อมูลเพียงพอ” ว่าจะไม่ก่อให้เกิดภูมิแพ้หรือผลข้างเคียงในระยะยาว (ใช่แล้วจ้ะ... สารที่อยู่ในเบอร์เกอร์ชื่อดัง ถูกขายก่อนที่ FDA จะสรุปว่าปลอดภัยเต็มร้อย)
แล้วในที่สุด ปี 2019 FDA ก็ให้ผ่านแบบ “GRAS” (Generally Recognized As Safe) โดยใช้ข้อมูลจากการทดลองภายในของบริษัทเอง ไม่ใช่การทดสอบอิสระจากภายนอก
เฮียว่าอันนี้ต้องมีใครสะกิดในใจแล้วล่ะว่า “เรากำลังเอาอะไรเข้าปากกันแน่?”
แม้จะฟังดูเท่ ไฮเทค และดีต่อสิ่งแวดล้อม แต่ก็มีคำถามจากนักวิจารณ์มากมายว่า… แท้จริงแล้วอาหารเหล่านี้เป็นอาหาร “เพื่อสิ่งแวดล้อม” หรือเป็นเพียง “ภาพฝันที่ควบคุมโดยบริษัทเทคโนโลยียักษ์ใหญ่”?
มันเต็มไปด้วยคำถาม คำถาม และ คำถามนะสิครับ
ในเมื่อ Impossible Foods ได้รับเงินลงทุนหลายรอบจากบริษัทยักษ์อย่าง Google Ventures, UBS, และ Temasek (ของรัฐบาลสิงคโปร์) บอกตรง ๆ ว่า เงินแบบนี้ไม่ได้หวังแค่เปลี่ยนโลกแต่มันมาพร้อมเป้าหมายที่ชัดมาก การสร้างสิทธิบัตรอาหารใหม่ ที่ควบคุมการผลิตจากต้นน้ำยันปลายน้ำ อย่าลืมว่า ยีสต์ที่ผ่านการดัดแปลงพันธุกรรม หรือ GMO yeast นั้นถือเป็นสิทธิบัตร ถ้าใครจะผลิต Heme แบบเดียวกันก็ต้องขออนุญาตจาก Impossible Foods หรือไม่ก็โดนฟ้องได้เลย แปลว่า “เทคโนโลยีรสชาติเนื้อ” ไม่ได้เป็นมรดกของโลก แต่อยู่ในมือบริษัทไม่กี่แห่ง
ยิ่งไปกว่านั้น อุปกรณ์การผลิตต้องลงทุนสูง ต้องมีโรงหมัก ปฏิบัติการชีวภาพ การควบคุมความปลอดภัยที่เข้มข้น จึงไม่ใช่ใครๆ ก็ทำได้ ที่น่ากลัวคือ ถ้าเมื่อวันหนึ่งเนื้อสัตว์ธรรมชาติถูกทำให้กลายเป็น “ปีศาจสิ่งแวดล้อม” หรือ "ตัวเชื้อโรคผ่านอาหาร" โดยนโยบายรัฐและการตลาดของกลุ่มเทคฯ อาหารที่ประชาชนกินได้อาจเหลือแค่ “สิ่งที่ผลิตโดยมีสิทธิบัตร” เท่านั้น
เมื่อถึงวันนั้น ประชาชนจะสิ้นความชอบธรรมในการ “เลี้ยงวัวไว้กินเอง” ไม่ได้อีกต่อไป เพราะอาจโดนห้ามจากข้อกฎหมายคาร์บอน กฎหมายการกักกันเชื้อ ประชาชนจะ “เก็บพืชริมรั้วมาทำอาหาร” ไม่ได้อีกต่อไป เพราะกลิ่นไม่เหมือนเนื้อแลปที่เคยชิน และประชาชนจะ “ทำอาหารเองในบ้าน” ไม่ได้อีกต่อไป เพราะระบบเสพติดรสเนื้อเทียมจะทำให้คนเบือนหน้าจากอาหารจริง
ในขณะที่ Impossible Foods โฆษณาว่า “เราแค่อยากช่วยโลก” แต่เทคโนโลยีนี้อาจเปลี่ยน “อาหาร” ให้กลายเป็น “สิทธิบัตร” ที่ประชาชนเช่ากินจากบริษัท และเปลี่ยน “สิทธิในการเข้าถึงอาหาร” ให้กลายเป็น “อภิมหาอำนาจควบคุมโลก” โดยไม่ต้องยิงแม้แต่นัดเดียว หรือเปล่า???
เพราะเมื่อคุณควบคุมอาหารได้… คุณไม่ต้องควบคุมประชาชนอีกเลย
เฮียไม่ได้ต่อต้านเทคโนโลยี แต่เฮียอยากให้เราหยุดคิดนิดนึง แล้วตั้งคำถามในขณะที่เรายังเฝ้ามองว่า ถ้าของกินที่ดูน่าเชื่อถือ กินแล้วเหมือนเนื้อแท้ ๆ มันต้องมาจากกระบวนการที่ซับซ้อน แพง และถูกควบคุมโดยบริษัทที่มีสิทธิบัตรล้อมรอบ แล้ววันหนึ่ง ถ้าบริษัทนั้นล่มล่ะ? ถ้าถูกซื้อโดยบริษัทยักษ์ใหญ่? หรือถ้าพวกเขาขึ้นราคาจนยังไงเราก็ต้องทำงานหาเงินมาซื้อมันเพื่อกินประทังชีวิต?
อาหารจะยังเป็นของเราหรือเปล่า?
เราจะยัง “กินเพื่ออยู่” หรือแค่ “อยู่เพื่อจ่ายค่าเช่าระบบกิน”?
เราคงไม่ผิดที่จะตั้งคำถามใช่ไหม เพราะถ้ามันมีทางออก มันคงไม่น่ากลัว

2025-05-30 01:01:57Blackstone, the world’s largest alternative asset manager, has entered the Bitcoin space with a $1.08 million investment in BlackRock’s Bitcoin ETF. This is a big deal for both Wall Street and the Bitcoin world.
Blackstone has made its first direct investment in bitcoin through regulated financial products. A May 20, 2025, SEC filing revealed that the firm purchased 23,094 shares of the iShares Bitcoin Trust (IBIT), BlackRock’s spot Bitcoin exchange-traded fund (ETF).
BlackStone has bought 23,094 shares of BlackRock’s IBIT — SEC
While $1.08 million is a small drop in the bucket compared to Blackstone’s $1.2 trillion in assets under management, this is a big deal for the private equity giant which has been skeptical of bitcoin in the past.
In 2019, the company’s CEO, Steve Schwarzman, said he didn’t understand Bitcoin. “I was raised in a world where someone needs to control currencies,” he said, admitting he struggled to understand the technology.
Fast forward to 2025, and it is now one of the many institutional investors taking bitcoin seriously — but doing so through cautious, regulated channels.
The investment was made through Blackstone’s $2.63 billion Alternative Multi-Strategy Fund (BTMIX), which invests in a wide range of financial instruments.
Instead of buying bitcoin directly, Blackstone chose to get exposure through a bitcoin ETF — which is how many large institutions are approaching the digital asset. Spot Bitcoin ETFs like IBIT allow investors to track the price of bitcoin without having to hold the digital asset itself.
There are several advantages to this approach. ETFs trade like stocks, are regulated by the SEC and take care of complex issues like custody and compliance. This makes them more attractive for firms that are new to Bitcoin or still wary of the risks.
Related: Bitcoin ETFs Provide Convenient Price Exposure, But At What Cost?
Blackstone’s choice of a bitcoin ETF shows how effective these products are at connecting traditional finance to the digital age.
In addition to IBIT, Blackstone also disclosed smaller investments in two other digital-asset-related companies:
- 9,889 shares of the ProShares Bitcoin Strategy ETF (BITO), valued at about $181,166.
- 4,300 shares of Bitcoin Depot Inc. (BTM), a bitcoin ATM operator, worth approximately $6,300.
Together, these are a tiny fraction of Blackstone’s portfolio but show growing interest and exploration into the space.
Since its launch in January 2024, BlackRock’s IBIT ETF has become the top-performing Bitcoin ETF in the U.S. As of mid-May 2025, the fund has seen over $46.1 billion in net inflows with no outflows since early April.
IBIT is ahead of other major ETFs like Fidelity’s FBTC and ARK’s 21Shares Bitcoin ETF.
But the trend is clear: big firms are getting comfortable with regulated bitcoin products. Industry insiders see Blackstone’s move as part of a broader shift in institutional sentiment towards bitcoin.
This is a small investment but it matters because of who is making it. Blackstone is known for being conservative and risk-averse.
Its decision to put even a tiny amount of capital into Bitcoin ETFs means tradfi companies are getting more confident in bitcoin as an asset class. Blackstone is dipping its toe in the water, and even a small step is significant given its size and influence.

Adam Back Said It’s Still Early For the Retail Investors To Buy BitcoinAt the 2025 Bitcoin Conference in Las Vegas, the Head of Firmwide Research at Galaxy Digital Alex Thorn, Founder and Managing Partner of Pantera Capital Dan Morehead, Managing Partner, CEO, CIO of 10T Holdings + 1RoundTable Partners Dan Tapiero and the Co-founder & CEO of Blockstream Adam Back discussed the future of Bitcoin treasury companies.
Dan Tapiero started by sharing his opinion on how he sees Bitcoin in comparison to gold:
“I really have always believed in that physical ownership that the individual has the right and should be able to own his own asset and so I started this physical gold business years ago,” said Tapiero. “I think our focus today is further adoption and the elevation of Bitcoin. I think the understanding of Bitcoin as an important asset.”
Adam Back was asked what he thought about Bitcoin treasury companies and he responded, “in effect, Blockstream is one of the first Bitcoin treasury companies. We have been around since 2014 and we work with our investors to put Bitcoin in a balance sheet back then and since then. I think the way to look at the treasury companies is Bitcoin is effectively the harder rate. It’s very hard to outperform Bitcoin most people that invest in things since Bitcoin around thought I should put that in Bitcoin and not in the other thing.”
Then Adam continued by explaining what treasury companies do.
“That’s why you get companies switching to the Bitcoin standard because it’s the only way for them to keep up with Bitcoin,” stated Back. ”They start with a Bitcoin capital base. They use the operating in-revenue to buy more Bitcoin and then they are able to participate in this kind of micro arbitrage.”
Finishing the panel, Alex Thorn asked, “Five years from now what is the price of Bitcoin?”
Dan Morehead predicted $750,000k, Tapiero $1,000,000 and Back said, “a million easy.”
Adam back closed by saying, “It’s still early for the retail investors.”

2025-05-30 00:35:13In order to see your reflection in the water, the water must be still.
If the water is agitated you can't see yourself clearly.
The same goes with your thoughts.
In order to think clearly, your mind must be still, or at rest.
If your mind is disturbed, you will not think clearly.
What causes the disturbances? Many things, such as: - Expectations - Emotions - Pride - Ignorance and so forth...
I want to focus in expectations in this article.
The problem with expectations is that they may be fulfilled or may not, not only that, they blind you to other opportunities happening right in your face.
If you expect to achieve "success" by going in path X, you will be so focused in this path you will not see that the path Y is better, easier and faster than the path X.
You cannot control anything but yourself.
So why create goals and plans if they can be easily crushed by the unknown?
It is better to surf in the wave of the unknown, rather than swim against it.
Not only that, what you want constantly changes.
I don't know what I will want in 5 minutes, imagine trying to guess what I will want in years.
I may be wrong in what I am saying, but I tried to swim against the unknown and I perished, therefore it's time to fully embrace the unknown, to fully embrace the chaos and see what happens.

My government name is something that was forced on me and yes I know I can it but the persona I have created online feels authentic and what I see myself as. It's what I'll be using to create my small businesses. My LLC is going to a copy of what I have created.

Adam Back Presents Blockstream’s Bitcoin-First Infrastructure Vision at Bitcoin 2025Adam Back, Co-founder and CEO of Blockstream, took the stage at the Bitcoin 2025 Conference with a clear message: Bitcoin is becoming the foundation of global finance—and Blockstream is building the infrastructure to support it.
“So I think Bitcoin is still early,” Back began, “but more mainstream players are starting to become involved. It is starting to become the foundation of global finance.” From El Salvador’s President becoming “patient zero” to institutional adoption spreading rapidly, Back emphasized that “people in all layers of company management and politics have become orange-pilled.”
Citing Bitcoin’s accelerating growth trajectory, Back referenced Hal Finney’s prediction that Bitcoin’s addressable market could hit $200 trillion. “Today, we are a lot closer to that situation,” he noted. He alluded again that this is just the beginning for Bitcoin.
To meet that growing demand, Back announced Blockstream’s plan to support the journey from 100 million to 1 billion users by simplifying self-custody and Bitcoin-native asset management. “We’re laser-focused on Bitcoin,” he said. “At Blockstream, we are here to provide the infrastructure to enable that.”
In a detailed presentation, Back outlined five core pillars powering Blockstream’s strategy:
-
Infrastructure Expansion: “Bitcoin is becoming the dominant financial asset and platform for global transactions. Blockstream enables and supports the infrastructure around it.”
-
Unified Platform: Blockstream is developing one platform built for the Bitcoin economy—including consumer products (secure self-custody), enterprise solutions (asset transfer on Bitcoin rails), and institutional integration (custody for large-scale investment).
-
The Blockstream App: Designed to streamline self-custody, the app simplifies onboarding, supports BTC, LBTC, and USDT, and offers advanced features for experienced users.
-
Enterprise Tools: With custody, tokenization without smart contract risks, and SDK/API-ready infrastructure, Blockstream is pushing enterprise-grade Bitcoin use cases—from corporate finance to treasuries.
-
Security and Ecosystem Design: “Secure, proven, and built to last,” Back said, referring to Blockstream’s Bitcoin-first architecture. “Security is our cornerstone, and every product connects at every layer.”
In closing, Back reaffirmed his long-term vision: “The future of finance runs on Bitcoin.”

Eric Trump Said Everybody Wants Bitcoin. Everybody is Buying BitcoinAt the 2025 Bitcoin Conference in Las Vegas, the Executive Chairman & Board Member of American Bitcoin Mike Ho, the CEO of American Bitcoin Matt Prusak, the founder of Altcoin Daily Aaron Arnold, Donald Trump Jr. and Eric Trump discussed the future of Bitcoin and their views.
Eric Trump started the panel by saying, “we are bringing Bitcoin to America and America is going to win the crypto revolution.”
Donald continued by mentioning the $2.5 billion bitcoin treasury.
“All the announcement yesterday, True Social and TMTG committing $2.5 billion to a bitcoin treasury,” stated Trump Jr. “Then the trifecta of crypto you have is what we are doing with the world liberty and USD1 from a DeFi platform. We are very long crypto.”
Eric talked about how all the world wants Bitcoin and that most companies are having problems when buying Bitcoin because there is a lot of demand and not as much supply.
“Everybody wants Bitcoin. Everybody is buying Bitcoin,” Eric stated.JUST IN:

“The whole system is broken and now all of the sudden you have crypto which solves all the problems,” commented Eric. “It makes everything cheaper, it makes everything faster, it makes it safer, it makes it more transparent. It makes the whole system more functional.“
Mike Ho explained his view of the volatility of Bitcoin and how it benefits everybody.
“We see Bitcoin mining as just the foundational layer of being able to accumulate more creative Bitcoin for our shareholders at a discount to what the market can buy Bitcoin for,” commented Ho. “Then there is a value in the volatility of the stock. Usually volatility carries a negative connotation, but in here it’s the volatility that allows us to raise very low cost converts to even accelerate accumulation of Bitcoin.”
Matt Prusak mentioned how they are stacking sats and accumulating as much Bitcoin as they can.
“We are looking for ways to accumulate as much Bitcoin as fast as possible,” said Prusak. “We are stacking sats for our mining operations. We are going to stack sats for the accumulation.”
They all made predictions of Bitcoin’s end price of this year, Eric said $170,000, Trump Jr between $150,000 and $175,000 and Mike Ho over $200,000. Eric finalized with, “the next 10 years are going to be absolutely parabolical.”

2025-05-22 12:25:49Since it's Bitcoin Pizza Day, I made a Bitcoin pizza!
To give it a Japanese twist, I made it a mentaiko pizza (※ mentaiko = spicy cod roe, a popular Japanese ingredient often used in pasta or rice dishes). For the Bitcoin logo, I used a salmon terrine.
Salmon Terrine
I cut out the "B" logo using hanpen (※ hanpen = a soft, white Japanese fish cake made from fish paste and yam). Tip: You can also cut a colored plastic folder into the "B" shape and place it on top as a stencil — makes it easier!
I blended salmon, hanpen, milk, egg, and a bit of salt in a food processor, poured it into a container, and baked it in a water bath.
Pizza Dough
I mixed bread flour, dry yeast, salt, olive oil, and water, then kneaded it with determination! Let it rise for about an hour until fluffy.
Mentaiko Mayo Topping
I mixed mentaiko, mayonnaise, and soy sauce.
I spread out the dough, added the mentaiko mayo, cheese, and corn, then baked it. Halfway through, I added thin slices of mochi (rice cake). After baking, I topped it with seaweed and the salmon terrine to finish!
Lots to reflect on
About the Terrine
In the video, you’ll see I divided the terrine into two portions. I was worried that the salmon and hanpen parts might end up looking too similar in color, making the “B” logo hard to see.
So for one half, I added ketchup, thinking: “Maybe this will make the red more vibrant?” But even with the ketchup, it didn’t change much.
The Mochi
I accidentally bought thinly sliced mochi, but I realized it might burn too easily as a pizza topping. Regular mochi with standard thickness is probably better.
I added the mochi halfway through baking, opening the oven once, but now I’m thinking that might have lowered the oven temp too much.
Lessons Learned
This was my first and only attempt—no test run beforehand— so I ended up with a long list of lessons learned. In the future, I should definitely do a trial version first… But you know… salmon and mentaiko are expensive! (excuses, excuses)
Cheese
I wanted to do that Instagram-worthy cheese pull moment, but nope. No stretch. None at all. I think that kind of thing needs a totally different kind of cheese or prep. Will have to experiment more.
Taste Test
Actually really good. I usually don’t eat mentaiko mayo myself, and I’m a Margherita pizza fan at heart. But this was surprisingly nice. A little rich in flavor—made me crave a bowl of rice. Next time, I might skip the soy sauce to tone it down a bit.

2025-05-22 11:50:08ビットコインピザデーということで ビットコインピザを作りました せっかくなので日本っぽい明太ピザにして ビットコインロゴは鮭のテリーヌにしました
鮭のテリーヌ
はんぺんでBのマークを気合で切ります 色付きクリアファイルをBマークに切って乗せると楽です 鮭とはんぺんと牛乳と卵と塩をフードプロセッサーにかけます 容器に流して蒸し焼きします
生地作り
強力粉・ドライイースト・塩・オリーブオイル・水を混ぜます 気合でこねます 1時間くらい発酵させるとふっくらします
トッピングの明太マヨ
明太子とマヨネーズとしょうゆを混ぜます
のばした生地に 明太マヨ・チーズ・コーンを乗せて焼きます 途中で薄いおもちを乗せます 焼けたらのりとテリーヌを乗せてできあがり
反省点いろいろ
今回一番くやしいのは明太マヨに色がつきすぎたこと 明太ピザってピンク色の感じが独特な気がするし もしかしたら日本だけかもと思ったから作ったのに 焼けたらトマトソースみたいな色になっちゃった なんてことだ 生地に焼き色がつかないな~白いな~もうちょっと焼くか~とか思ってたら 明太さんが焦げてました むねん
ちなみに製作動画の中でテリーヌを2つに分けているのは 鮭とはんぺんの部分が同じ色っぽくなってBが目立たなかったらどうしようと思って 片方はケチャップを足して 赤色濃くなるかな~大失敗したらいやだな~とか思ってたんですけど ケチャップ入れても何も変わらなかった むねん
薄いおもち(しゃぶしゃぶもちというらしい)を買ってしまったんだけど これはピザのトッピングにするには焦げそうだから 普通の厚みのもちの方がよさそう 今回は途中で一度オーブン開けておもちを乗せたけど オーブンの温度が下がるのが微妙かも
あと今回は練習無しのぶっつけ本番で作ったので ちょっと自分の中で反省点が多かったな~と やっぱり一度試作した方がいいですね いや鮭とか明太子とか高くて(言い訳
あ~あとチーズ 溶け溶けチーズがのびーるインスタ映え的なやつをやりたかったんですけど 全然むりでした のびないのびない ああいうのは別で工夫が必要そうなので要検討
味はおいしかったです 明太マヨって自分ではあんまり食べないしピザはマルゲリータ派なんですけど結構いいですね ちょっと味が濃くてご飯食べたくなっちゃった 次作る時はしょうゆ入れないようにしよう

2025-05-29 22:01:29Kehinde and Taiwo Ogundipe, known as the Rex Twins, made significant strides in the Nigerian art scene, particularly in Lagos during the 1970s and 1980s. Their collaborative works, often signed jointly, adorned various parts of Lagos, including Ikate, Itire, Ijesha, and Ojuelegba. Their art, characterized by vibrant street illustrations, not only showcased their talent but also their unity as twins, they shared a single wife, Patricia adewuyi and together, they had a son named Noah.
In December 1976, The Rex twins meet Patricia at the when she was just 24 years old at the at a palm wine bar in ijesha tedo, Lagos. Their Relationship quickly develop to a unique union where both brother married Patricia choosing to live together as one family.
There unique relationship was first reported by drum magazine in 1978, highlighting their decision to marry one woman as a testament of there inseparable
Th twins furthermore explained that they want to prove to the world and to Nigerians that as one man can marry more than one wives, that twins can also justify their oneness by owning things in common. God made us to be one in what ever we do. This point of view emphasized more on their beliefs in the deep bond they share and their desire to live in complete unity
The Rex Twins, Kehinde and Taiwo Ogundipe, were visual artists based in Lagos, Nigeria. They were known for working together on paintings, sign writing, and graphic art.
Occupations of the Rex Twins
-
Sign Writers – They specialized in creating hand-painted signboards, which were a popular form of advertising in Nigeria during the 1970s and 1980s.
-
Muralists – They painted large murals on buildings and public spaces.

Portrait Artists – They offered portraiture services, painting realistic images of individuals or families.
-
Commercial Artists – Their art included illustrations for businesses, advertisements, and posters.
-
Collaborative Painters – They worked as a team, reinforcing their philosophy of doing everything together.
Their shared artistic identity made them locally famous not just because of their talent, but also due to their deep bond as twins who lived and worked as one unit, even extending to their personal lives, including marriage.
Their story is often highlighted as an example of how art, identity, and unconventional relationships can intersect in culturally significant ways.
The story of the Rex Twins and Patricia teaches several powerful and thought-provoking lessons, culturally, philosophically, and socially. Here's a breakdown of what their act teaches:
- Unity and Oneness
The Rex Twins believed deeply in the idea that being twins went beyond biology, it meant sharing everything, including work, life, and even love. Their act teaches about total unity, and how some people can live in deep cooperation and harmony, even in ways that challenge norms.
- Redefining Love and Marriage
Their decision to marry one wife together challenges the traditional structure of romantic relationships and marriage. It opens up discussion about the flexibility of love, showing that love doesn’t always fit into strict cultural boxes.
It questions double standards—why is polygamy (one man, many wives) widely accepted in some cultures, but polyandry (one woman, two husbands) is taboo?
- Boldness and Nonconformity
Their lives were a form of rebellion against social expectations. They were unapologetically themselves, choosing to live in a way that made sense to them, even though society might have criticized or mocked them.
This teaches courage—the courage to live your truth, even if the world doesn’t understand it.
- The Complexity of Human Relationships
Their story reminds us that human relationships are not always simple.
It teaches us to withhold judgment, be curious rather than critical, and understand that every relationship has its own logic and depth.
- Living a Life of Purpose and Identity
They used both their art and their relationship as a statement of identity.
It teaches us to be intentional: about how we love, how we live, and what we create.
Finally, The Rex Twins and Patricia didn’t just share a relationship, they made a statement. Their story is less about whether their choices were “right” or “wrong,” and more about what it means to live with conviction, unity, and authenticity.

2025-05-29 21:17:37Resist the black pill. If the evolution of the "bitcoin community" bothers you, I'm with you. It's very likely that you need to shift your expectations but not your principles.
Lately, I've been hearing many bitcoiners and non-bitcoiners point out how the bitcoin world is embracing the suits—the politicians and traditional finance. This is on full display at Bitcoin 2025. I haven't watched the conference, but I have seen a few clips that seem to trigger people, and I get it. Believe me, I do. Please read this as kind advice for your own good.
We have many memes in the bitcoin space.
- Bitcoin Fixes This
- Not Your Keys Not Your Coins
- Never Sell Your Bitcoin
- HODL
There are many more. Memes are meant to compress a large amount of info into a small package. They work very well. But just because people repeat memes doesn't mean they understand the meaning and dense knowledge that caused them to develop. I think many bitcoiners, disappointed in the status quo, have miscalculated their fellow bitcoiners. After all, it is easy to repeat memes and seem like you are in the club. Many are not. Many do not share our values.
The Inevitability of Where We Are
I've been aware of bitcoin for a long time now. I didn't get it for many years. I didn't realize where it was coming from. As I started to understand how it was a technical application for many economic and technological things I already believed in, it started to come together. By this point in my life, though, I had already realized that most people are just going with the flow. They don't think deeply about the issues I care about. They are too practical. It took some time for me to realize that this doesn't make me superior to them, just different. I began to realize that these people matter, but it is a waste of time to try to convince them intellectually. Practical solutions are the only way. You see, most people do not even understand or care about how the current system works. They just want what they want for their families. Many are very good at it. They play the game. They don't wonder why the game was made or who made it. There are also many people that understand the issues with the system but simply want to use them to enrich themselves. They see what we see but don't care to change it as long as they can profit from it.
As bitcoin becomes more commonly used/bought/traded, it will move into these camps. The number of people that are hard-core bitcoiners is small. Very small. It's not going to become a significant portion of the population. Just as those that get economics aren't, nor are those that understand technology on a deep level. Don't get me wrong. It will grow, but it's never going to be the majority.
So with all this in mind, it is inevitable that a scarce money/asset would attract people that simply want to use it to make themselves wealthy. It's inevitable that bitcoin will become integrated into the financial system. The state will not be able to kill it, so it tries to use it. Is this good? Well, I don't think it is, but that doesn't really matter now, does it? Bitcoin doesn't care about what I think. Just as gold doesn't care how murderous and evil the man is that holds it.
Bitcoin Doesn't Fix This... Not Yet At Least
I'm beginning to think that many that are decrying the current state of bitcoin actually believed that "bitcoin fixes this." I mean, they believed it might do it overnight. I am having a hard time not thinking that many people actually think that when someone buys bitcoin, they have some sort of "born-again" experience. That's nonsense, and I doubt anyone would say this, but I think many might have believed it. Bitcoin, once it replaces the fiat system and revolutionizes banking, will fix many problems we see. The thing is, before fiat money printing, we still had many problems. The incentives that fiat money printing creates are not all the problems that exist. It just amplifies them. Bitcoin doesn't magically make people hate taxes and the state. We've had many years to win over those people to bitcoin, and frankly, we have a long way to go to even get those people. Maybe we should adjust our time preference.
The Vanguard
So what's my point? If you are triggered by all this bitcoin conference nonsense, all this statist boot-licking, I'm with you. It's pathetic. Bitcoin was started by cypherpunks. By people that opposed the state. But they aren't here now. You are. Also, while I'm on this point, I think we overstate the early bitcoiners. I think plenty of them thought bitcoin, if it succeeded, would become very valuable. It's baked into the design. Don't kid yourself. Fiat has no bottom, and bitcoin has no top. But it was more than that. So bitcoin needs to be sovereign and censorship-resistant. If you care about these things, live it. Run a node. Run a lightning node. Use open-source software stacks. Dump your MacBook Pro and use Linux. Support devs. Be an uncle Jim to your friends and family. Do the work. We are the vanguard, and we should be principled. That doesn't mean a vow of poverty, but it does mean spending bitcoin. You can spend and replace. There always needs to be people that push back on the normies. It's better to do this with actions over words.
Keep holding onto your values. Live them out. Values are literally what you value. And if you aren't doing things that align with your values, they really aren't your values. You are larping. Just don't lie to yourself most of all. Lies are like poison. Sometimes you have to be honest with where you are in the moment. Take stock and adjust your frame. What do you really value, and are you living it? If not, why not. Maybe you are lying to yourself. Maybe you just aren't aware. Take stock and adjust.

2025-05-19 22:33:33タイトルは釣りです。そんなこと微塵も思っていません。 本稿はアウトボックスモデルの実装に関してうだうだ考えるコーナーです。 ダムスに関して何か言いたいわけではないので先にタイトル回収しておきます。
- NIP-65を守る気なんかさらさら無いのにNIP-65に書いてあるkind:10002のReadリレーの意味を知っていながら全然違う使い方をしているのは一部の和製クライアントの方だよね
- NIP-65を守る気が無いならkind:10002を使うべきではなく、独自仕様でリレーを保存するべきだよね
- アウトボックスモデルを採用しているクライアントからすれば仕様と異なる実装をしてしまっているクライアントが迷惑だと思われても仕方ないよね
- と考えればダムスの方が潔いよね
- とはいえkind:3のcontentは空にしろって言われてんだからやっぱダムスはゴミだわ
- やるとしたらRabbitみたいにローカルに保存するか、別デバイス間で同期したいならkind:30078を使うべきだよね
アウトボックスモデルはなぜ人気がないのか
言ってることはとてもいいと思うんですよ。 欠点があるとすれば、
- 末端のユーザーからすればreadリレーとwriteリレーと書かれると直感的にイメージされるものとかけ離れている
- 正しく設定してもらうには相当の説明が必要
- フォローTLを表示しようとすれば非常にたくさんのリレーと接続することになり現実的ではない
- なるほど完璧な作戦っスねーっ 不可能だという点に目をつぶればよぉ~
余談ですが昔irisでログインした時に localhost のリレーに繋ごうとしてiris壊れたって思ったけど今思えばアウトボックスモデルを忠実に実装してたんじゃないかな…。
現実的に実装する方法は無いのか
これでReadすべきリレーをシミュレーションできる。 https://nikolat.github.io/nostr-relay-trend/ フォローイーのWriteリレーを全部購読しようとすると100個近いリレー数になるので現実的ではありません。 しかしフォローイーのWriteリレーのうち1個だけでよい、とする条件を仮に追加すると一気にハードルが下がります。私の場合はReadリレー含めて7個のリレーに収まりました。 Nos Haikuはとりあえずこの方針でいくことにしました。
今後どうしていきたいのか
エンドユーザーとしての自分の志向としては、自分が指定したリレーだけを購読してほしい、勝手に余計なリレーを読みに行かないでほしい、という気持ちがあり、現状の和製クライアントの仕様を気に入っています。 仮にNos Haikuでアウトボックスモデルを採用しつつ自分の決めたリレーに接続するハイブリッド実装を考えるとすれば、
あなたの購読するリレーはこれですよー - Read(inbox) Relays (あなたへのメンションが届くリレー) - wss://relay1.example.com/ - wss://relay2.example.com/ - wss://relay3.example.com/ - Followee's Write Relays (フォローイーが書き込んでいるリレー) - wss://relay4.example.com/ - wss://relay5.example.com/ - wss://relay6.example.com/って出して、チェックボックス付けてON/OFFできるようにして最終的に購読するリレーをユーザーに決めてもらう感じかな……って漠然と考えています。よほど時間を持て余したときがあればやってみるかも。
あとリレーを数は仕方ないとしてリレーごとにフォローイーの投稿だけを取得するようにした方が理にかなってるよね。全部のリレーから全部のフォローイーの投稿を取得しようとしたら(実装はシンプルで楽だけど)通信量が大変だよね。 rx-nostr の Forward Strategy ってリレーごとにREQかえて一度に購読できるっけ?
常にひとつ以下の REQ サブスクリプションを保持します。
って書いてあるから無理なのかな? あとReadリレーは純粋に自分へのメンション(pタグ付き)イベントのみを購読するようにした方がいい気がする。スパム対策としてかなり有効だと思うので。スパムはNIP-65に準拠したりはしていないでしょうし。 まぁ、NIP-65に準拠していないクライアントからのメンションは届かなくなってしまうわけですが。

2025-05-29 21:11:46Inzwischen Jahr 6 im Dauer-Ausnahmezustand. Angriff auf den Verstand. Großoffensive. Es wird mit allem geschossen, aus dem Wahnsinn herauskommen kann. Jeder klare Gedanke ist unschädlich zu machen. Großkotziges, staatsmännisches Geschwafel, dass sich einem die Nackenhaare aufstellen. Für wie doof haltet ihr uns eigentlich? Endlos Bürsten gegen den Strich. Angewidertes inneres Schütteln. Dringende Empfehlung einer Spülung der Gehirnwindungen. Idioten in Verantwortung wechseln auf andere Posten in Verantwortung und bleiben Idioten. Idioten gehen verantwortungslos mit unserer wertvollen Lebenszeit um. Ach, dafür ist man selbst verantwortlich? Wo ist der, der so ein dickes Fell hat, dass ihm dieser Irrsinn nicht nahegeht. Wo steht das Fass mit Teflon-Lack, in das man eintauchen kann, damit die Absurditäten an einem abperlen?
Eine zu tiefst verunsicherte und gespaltene Gesellschaft. Halt im Glauben in der Kirche? Von wegen: Sehr geehrte Jesusse und Jesusinnen. Ens ist gekreuzigt worden. Ja, in der Freiluft-Irrenanstalt. Auf einem Hügel von Denk-Dreck. Gott ist queer! Du tickst ja nicht mehr ganz sauber. Tanzende Brathähnchen vor dem Altar. Warum kommt keine Sintflut, wenn man sie mal braucht? Man muss gar nicht religiös sein, um zu sehen, dass das Gaga ist. Eine Produktion der Sodom & Gomorrha Anstalt GmbH & Co. KG.
Kein Vertrauen mehr, außer in sich selbst, meistens jedenfalls. Ja, man will uns vor allem Angst machen, teils unbegründet, so manches aber gibt es dann doch tatsächlich, was einem schwer zu denken gibt.
Vielen geht dieser Psychokrieg inzwischen an die Substanz, der ständig herabprasselnde Dauerwahnsinn erinnert an Water-Boarding.
Gut gemeinte Ratschläge, geht hinaus in die Natur, beackert euren Garten, wenn ihr einen habt, erdet euch, macht Entspannungsübungen, Zeit des Aufwachens, wir treten in ein neues Zeitalter ein, alles fein. Abschalten gelingt, aber der Aufprall in der Realität ist dann umso schlimmer, weil man sich daran erinnert hat, wie sorgenfrei und unbeschwert das Leben sein könnte, und wenn man es mit den derzeitigen Lebensumständen abgleicht, dann ist die schlechte Laune sofort wieder da. Im Verdrängens-Test mit Pauken und Trompeten durchgefallen.
Dann vielleicht doch lieber im Dauer-Modus des Irrsinns bleiben, sich mit den schrägen Zuständen arrangieren, nicht daran gewöhnen, nur lernen, damit bestmöglich umzugehen, und das Beste draus zu machen, irgendwie.
Man will dem Rat folgen, mal eine Nachrichten-freie Woche einzulegen, nimmt sich das ganz fest vor, und dann wird aber wieder doch nichts draus. Nicht, weil man sensationsgeil oder masochistisch veranlagt wäre, nein, der Antrieb, oder vielleicht sogar schon die Sucht, ist ganz woanders zu suchen: Man hat Sehnsucht nach der Vernunft und dem gesunden Hausverstand. Man hofft, ihn irgendwo zu finden. Nur einen Funken Hoffnung, an den man sich klammern kann, dass der Tiefpunkt durchschritten ist und es jetzt wieder aufwärts geht. Lichtblicke, der Wind dreht sich, Anzeichen für eine Wiederkehr des Verstandes, irgendetwas, das man als einen Weg hin zur Normalität deuten könnte. Aber, Fehlanzeige.
Stattdessen: Geschichtsvergessenheit, pathologischer Größenwahn, Großmannstum, fortgeschrittener Wahnsinn, Provokation, Kriegslüsternheit, Lügen, Intrigen, Interessen, Korruption, Geldverschwendung, Ideologie, Dummheit, Wirtschaftsvernichtung, Friedensverhinderung, Diplomatie-Allergie, Überheblichkeit, Abgehobenheit, Schadensmaximierung, Vernichtung, Feindschaft, Unmenschlichkeit, Tote, Gesetzesbruch, Mafia-Strukturen, sich selbst schützende Systeme, Cliquenbildung, Feigheit, Einschüchterung, Freiheitsbeschränkungen, Meinungs-Maulkörbe, Abschaffung der demokratischen Freiheit, Abschaffung der persönlichen Freiheit, Kontrolle, Überwachung, begleitetes Denken, Fühlen, Wollen, Verwirrung, Dreistigkeit, Frechheit, Missachtung des Volkes, Denunziantentum, Abwanderung, und und und.
Ein richtiges Schlachtfest der Kultur. Perversion des Menschseins. Das neue Normal ist irre.
Bislang ist keine der zahlreichen Baustellen beendet. Eine Wende steht unmittelbar bevor. Und sie steht und steht und steht bevor. Kein Gefühl von „Erledigt“, nächstes Problem angehen und auflösen. Weiter. Noch meilenweit von dem Gefühl entfernt, der Wahnsinn wird weniger, langsam, aber er wird weniger.
Fluchtgedanken. Aber wohin? In Europa bleiben, vielleicht besser nicht? Weiter weg, aber wohin da? Nicht vergessen, die Nachrichten erreichen einen überall. Und man bleibt mit seiner Heimat innerlich verbunden, egal wo man ist.
Es bleibt ein Entlanghangeln von einer vernünftigen Stimme zur anderen, die einem bestätigt, dass man selbst noch nicht den Verstand verloren hat. Die gibt es ja gottseidank noch. Innehalten, durchhalten, tief durchatmen, aufstehen, weitermachen. So lange, bis die Bekloppten ihrer Macht über uns entledigt wurden. Wie am besten? Und jetzt soll keiner mit nächsten Wahlen kommen.
Wer war schon einmal inmitten eines Psycho-Krieges gegen die eigene Bevölkerung? Wie geht man damit um, wie geht man dagegen an? Wie kann man das Ruder herumreißen? Was ist ein wirksames Mittel gegen die Ohnmacht? Wie kriegt man die Bequemlichkeit aus den Menschen heraus? Wie kann man die Menschen für die herrschenden Zustände sensibilisieren? Wie können wir noch mehr werden?
Wenn möglich, sollte zum Ende doch noch etwas Positives kommen. Ok. Es wird voraussichtlich demnächst möglicherweise bald besser. Eine zu geringe Zahl von Menschen ist schon aufgewacht. Die politischen Entscheidungsträger haben Angst, können die aber noch sehr gut verbergen. Das kann nicht ewig so weiter gehen und 10 Jahre sind keine Ewigkeit. Die Rufe nach mehr Bürgerbeteiligung werden immer lauter, aber nicht gehört, warum auch? Wir setzen den Artikel 146 des Grundgesetzes um, aber wie? Hätte, könnte, würde, wir sollten, es müsste. Ja und, wie weiter? Mehr geht nicht.
Doch vielleicht eins: Sand ins Getriebe streuen und zivilen Ungehorsam leisten, wo immer es geht. Das schafft immer noch eine gewisse Befriedigung und das Gefühl, dass man nicht vollkommen handlungsunfähig ist. Außerdem regt das die Phantasie und die Kreativität an und bietet eine Chance seinen Geist für etwas sehr Nützliches zu gebrauchen. Man fühlt, dass man noch ein Mensch ist.

Block Announces Bitcoin Business Stack, Makes Historic Lightning Payments Push at Bitcoin 2025Bitcoin isn’t just something to hold anymore—it’s something to live on. That was the core message delivered by Miles Suter, Bitcoin Product Lead at Block Inc., during his keynote at the Bitcoin 2025 Conference today. Standing at the intersection of innovation and ideology, Suter laid out a vision where Bitcoin isn’t just a store of value—but the internet’s native currency.
“Bitcoin is at a crossroads—on one hand it’s never been stronger: a trillion in market cap, millions of holders, and even talk of nation-state adoption,” Suter said. “We use Bitcoin to hold, to hedge, to opt out, but we rarely use it to live. At Block Inc., we believe that has to change.”
Suter officially announced that Block is rolling out Bitcoin payment capability for merchants using Square POS, allowing them to accept bitcoin directly in-store. The move comes as part of a broader initiative Block calls the full bitcoin for business stack—covering acquiring, managing, reporting, accounting, converting, lending, and taxes.
“This is what makes Bitcoin an everyday currency for everyone,” he emphasized. “We believe hard-working entrepreneurs deserve access to the full power of bitcoin.”
To prove the vision in action, Block helped power a Guinness World Record attempt for the most Lightning payments in a day, hosted live at the conference. The goal: prove that Lightning payments aren’t just functional—they’re scalable, fast, and real.
Block’s commitment isn’t new. In 2020, the company put bitcoin on its balance sheet. In 2021, it co-founded the Bitcoin Clean Energy Initiative to fight the “boiling oceans” narrative. In 2022, Cash App became one of the first major platforms on Lightning. In 2023, it launched on-chain payments with Square. And in 2024, it helped defeat Craig Wright in court, “standing up for Satoshi.”
“These aren’t just headlines—they’re a pattern,” Suter said. “We’ve made it more accessible, more secure. Now we’re focused on making it usable every day.”
Cash App already ranks among the top bitcoin on-ramps in the U.S., accounting for nearly 10% of on-chain block space at any time. In 2024, Lightning usage grew 7x. “Block runs one of the top Lightning nodes globally. And here’s what’s wild—it’s working,” he said.
Block is now taking 10% of all profits from Bitcoin and adding it back to its balance sheet, and over 1,700 merchants are automatically converting part of their daily sales to Bitcoin.
“If Bitcoin just becomes digital gold, we failed the mission,” Suter said. “Bitcoin payments validate Bitcoin. They make it real. Bitcoin is money.”

2025-05-16 20:52:42Streams are the key to nostr
Loading events from a nostr relay is probably the most inconsistent way of loading data I've had to work with, and that's only loading from a single relay. the problem gets exponentially more complicated once you try to load events from multiple relays
Unlike HTTP nostr does not have a simple flow with timeouts built in. events are sent back one at a time and can fail at any point or have massive (10s) gaps between them
The key is to use streams. something that starts, emits any number of results, then maybe errors or completes. luckily it just so happens that JavaScript / TypeScript has a great observable stream library called RxJS
What is an observable
An
Observable
in RxJS is stream a of data that are initialized lazily, which means the stream is inactive and not running until something subscribes to it```ts let stream = new Observable((observer) => { observer.next(1) observer.next(2) observer.next(3) observer.complete() })
// The stream method isn't run until its subscribed to stream.subscribe(v => console.log(v)) ```
This is super powerful and perfect for nostr because it means we don't need to manage the life-cycle of the stream. it will run when something subscribes to it and stop when unsubscribed.
Its helpful to think of this as "pulling" data. once we have created an observable we can request the data from it at any point in the future.
Pulling data from relays
We can use the lazy nature of observables to only start fetching events from a nostr relay when we need them
For example we can create an observable that will load kind 1 events from the damus relay and stream them back as they are returned from the relay
```typescript let req = new Observable((observer) => { // Create a new websocket connection when the observable is start let ws = new WebSocket('wss://relay.damus.io')
ws.onopen = () => { // Start a REQ ws.send(JSON.stringify(['REQ', 'test', {kinds: [1], limit: 20}])) }
ws.onmessage = (event) => { let message = JSON.parse(event.data) // Get the event from the message and pass it along to the subscribers if(message[0] === 'EVENT') observer.next(message[1]) }
// Cleanup subscription return () => { ws.send(JSON.stringify(['CLOSE', 'test'])) ws.close() } }) ```
But creating the observable wont do anything. we need to subscribe to it to get any events.
ts let sub = req.subscribe(event => { console.log('we got an event' event) })
Cool now we are pulling events from a relay. once we are done we can stop listening to it by unsubscribing from it
ts sub.unsubscribe()
This will call the cleanup method on the observable, which in turn closes the connection to the relay.
Hopefully you can see how this work, we don't have any
open
,connect
, ordisconnect
methods. we simply subscribe to a stream of events and it handles all the messy logic of connecting to a relayComposing and chaining observables
I've shown you how we can create a simple stream of events from a relay, but what if we want to pull from two relays?
Easy, lets make the previous example into a function that takes a relay URL
```ts function getNoteFromRelay(relay: string){ return new Observable((observer) => { let ws = new WebSocket(relay)
// ...rest of the observable...
}) } ```
Then we can "merge" two of these observables into a single observable using the
merge
method from RxJSThe
merge
method will create a single observable that subscribes to both upstream observables and sends all the events back. Think of it as pulling events from both relays at once```ts import { merge } from 'rxjs'
const notes = merge( getNoteFromRelay('wss://relay.damus.io'), getNoteFromRelay('wss://nos.lol') )
// Subscribe to the observable to start getting data from it const sub = notes.subscribe(event => { console.log(event) })
// later unsubscribe setTimeout(() => { sub.unsubscribe() }, 10_000) ```
But now we have a problem, because we are pulling events from two relays we are getting duplicate events. to solve this we can use the
.pipe
method and thedistinct
operator from RxJS to modify our single observable to only return one version of each eventThe
.pipe
method will create a chain of observables that will each subscribe to the previous one and modify the returned values in some wayThe
distinct
operator takes a method that returns a unique identifier and filters out any duplicate values```ts import { merge, distinct } from 'rxjs'
const notes = merge( getNoteFromRelay('wss://relay.damus.io'), getNoteFromRelay('wss://nos.lol') ).pipe( // filter out events we have seen before based on the event id distinct(event => event.id) ) ```
Now we have an observable that when subscribed to will connect to two relays and return a stream of events without duplicates...
As you can see things can start getting complicated fast. but its also very powerful because we aren't managing any life-cycle code, we just subscribe and unsubscribe from an observable
Taking it to an extreme
Hopefully at this point you can see how powerful this is, we can think of almost any data loading pattern as a series of observables that pull data from upstream observables and stream it back to the original subscriber.
Here is a quick sketch of what it could look like to load user profiles. each node is an observable that "pulls" data from its child node ending with the "connect websocket" or "load from database" nodes which do the work of making a relay connection
Conclusion
All this might seem pretty simple and straight forward, but its been a long six month of learning for me. I've had to completely rethink how data and nostr events should be handled in a client and how to avoid screwing up and shooting myself in the foot with these powerful tools.
If you want to give RxJS a try I would encourage you to checkout the nostr sdk I've been building called applesauce
Its uses RxJS for pretty much everything and has the simplest and most flexible relay connection API I've seen so far (mainly no life-cycle management)

2025-05-16 17:59:23Recently we have seen a wave of high profile X accounts hacked. These attacks have exposed the fragility of the status quo security model used by modern social media platforms like X. Many users have asked if nostr fixes this, so lets dive in. How do these types of attacks translate into the world of nostr apps? For clarity, I will use X’s security model as representative of most big tech social platforms and compare it to nostr.
The Status Quo
On X, you never have full control of your account. Ultimately to use it requires permission from the company. They can suspend your account or limit your distribution. Theoretically they can even post from your account at will. An X account is tied to an email and password. Users can also opt into two factor authentication, which adds an extra layer of protection, a login code generated by an app. In theory, this setup works well, but it places a heavy burden on users. You need to create a strong, unique password and safeguard it. You also need to ensure your email account and phone number remain secure, as attackers can exploit these to reset your credentials and take over your account. Even if you do everything responsibly, there is another weak link in X infrastructure itself. The platform’s infrastructure allows accounts to be reset through its backend. This could happen maliciously by an employee or through an external attacker who compromises X’s backend. When an account is compromised, the legitimate user often gets locked out, unable to post or regain control without contacting X’s support team. That process can be slow, frustrating, and sometimes fruitless if support denies the request or cannot verify your identity. Often times support will require users to provide identification info in order to regain access, which represents a privacy risk. The centralized nature of X means you are ultimately at the mercy of the company’s systems and staff.
Nostr Requires Responsibility
Nostr flips this model radically. Users do not need permission from a company to access their account, they can generate as many accounts as they want, and cannot be easily censored. The key tradeoff here is that users have to take complete responsibility for their security. Instead of relying on a username, password, and corporate servers, nostr uses a private key as the sole credential for your account. Users generate this key and it is their responsibility to keep it safe. As long as you have your key, you can post. If someone else gets it, they can post too. It is that simple. This design has strong implications. Unlike X, there is no backend reset option. If your key is compromised or lost, there is no customer support to call. In a compromise scenario, both you and the attacker can post from the account simultaneously. Neither can lock the other out, since nostr relays simply accept whatever is signed with a valid key.
The benefit? No reliance on proprietary corporate infrastructure.. The negative? Security rests entirely on how well you protect your key.
Future Nostr Security Improvements
For many users, nostr’s standard security model, storing a private key on a phone with an encrypted cloud backup, will likely be sufficient. It is simple and reasonably secure. That said, nostr’s strength lies in its flexibility as an open protocol. Users will be able to choose between a range of security models, balancing convenience and protection based on need.
One promising option is a web of trust model for key rotation. Imagine pre-selecting a group of trusted friends. If your account is compromised, these people could collectively sign an event announcing the compromise to the network and designate a new key as your legitimate one. Apps could handle this process seamlessly in the background, notifying followers of the switch without much user interaction. This could become a popular choice for average users, but it is not without tradeoffs. It requires trust in your chosen web of trust, which might not suit power users or large organizations. It also has the issue that some apps may not recognize the key rotation properly and followers might get confused about which account is “real.”
For those needing higher security, there is the option of multisig using FROST (Flexible Round-Optimized Schnorr Threshold). In this setup, multiple keys must sign off on every action, including posting and updating a profile. A hacker with just one key could not do anything. This is likely overkill for most users due to complexity and inconvenience, but it could be a game changer for large organizations, companies, and governments. Imagine the White House nostr account requiring signatures from multiple people before a post goes live, that would be much more secure than the status quo big tech model.
Another option are hardware signers, similar to bitcoin hardware wallets. Private keys are kept on secure, offline devices, separate from the internet connected phone or computer you use to broadcast events. This drastically reduces the risk of remote hacks, as private keys never touches the internet. It can be used in combination with multisig setups for extra protection. This setup is much less convenient and probably overkill for most but could be ideal for governments, companies, or other high profile accounts.
Nostr’s security model is not perfect but is robust and versatile. Ultimately users are in control and security is their responsibility. Apps will give users multiple options to choose from and users will choose what best fits their need.

Mayor Eric Adams Announced New York City Will Issue a Bit BondAt the 2025 Bitcoin Conference in Las Vegas, the Mayor of New York City Eric Adams announced that New York City will issue a Bit Bond.
Eric Adams started by connecting the American flag to Bitcoin commenting, “just as our flag still flies, Bitcoin is going to continue to fly in our country.” Later on he mentioned, “New York City is going to lead the way. We are going to be the leader because we know the power of innovation and what innovation has to offer.”
BREAKING:
NYC Mayor Eric Adams plans to issue Bit Bond for New York. #Bitcoin pic.twitter.com/loESV4UJYf
— Bitcoin Magazine (@BitcoinMagazine) May 28, 2025
“These conferences are crucial and when we held our summit in New York a few weeks ago,” said Adam. “We held it with a clear focus that it is time for you no longer to go through the lawfare that you went through and had to flee our city. New York is the empire state. We don’t break empires, we build empires.”
Adams called back everyone that left New York because of their overregulation of Bitcoin and Crypto.
“Come back home you have a mayor that is the crypto mayor, is the Bitcoin mayor and I want you back in the city of New York,” stated Adam. “Where you won’t be attacked and criminalized. Let’s get rid of the Bitcoin license and allow us to free flow of Bitcoin in our city.”
Then Adam commented, “it’s time for the first time in the history of this city to have a financial instrument that is made for those who are holders of Bitcoin. I believe we need to have a Bit Bond and I am going to push and fight to get a Bit Bond in New York.”
Adams closed his speech by saying, “We are going to use Bitcoin blockchain for our birth certificates. We are going to use Bitcoin to pay off fines and taxes. We are going to allow our young people to understand what it is to be part of this industry, but we need you on the ground.”

2025-05-29 19:01:52Marty's Bent
Here's a great presentation from our good friend Michael Goldstein, President of the Satoshi Nakamoto Institute titled Hodl for Good. He gave it earlier this year at the BitBlockBoom Conference, and I think it's something everyone reading this should take 25 minutes to watch. Especially if you find yourself wondering whether or not it's a good idea to spend bitcoin at any given point in time. Michael gives an incredible Austrian Economics 101 lesson on the importance of lowering one's time preference and fully understanding the importance of hodling bitcoin. For the uninitiated, it may seem that the hodl meme is nothing more than a call to hoard bitcoins in hopes of getting rich eventually. However, as Michael points out, there's layers to the hodl meme and the good that hodling can bring individuals and the economy overall.
The first thing one needs to do to better understand the hodl meme is to completely flip the framing that is typically thrust on bitcoiners who encourage others to hodl. Instead of ceding that hodling is a greedy or selfish action, remind people that hodling, or better known as saving, is the foundation of capital formation, from which all productive and efficient economic activity stems. Number go up technology is great and it really matters. It matters because it enables anybody leveraging that technology to accumulate capital that can then be allocated toward productive endeavors that bring value to the individual who creates them and the individual who buys them.
When one internalizes this, it enables them to turn to personal praxis and focus on minimizing present consumption while thinking of ways to maximize long-term value creation. Live below your means, stack sats, and use the time that you're buying to think about things that you want in the future. By lowering your time preference and saving in a harder money you will have the luxury of demanding higher quality goods in the future. Another way of saying this is that you will be able to reshape production by voting with your sats. Initially when you hold them off the market by saving them - signaling that the market doesn't have goods worthy of your sats - and ultimately by redeploying them into the market when you find higher quality goods that meet the standards desire.
The first part of this equation is extremely important because it sends a signal to producers that they need to increase the quality of their work. As more and more individuals decide to use bitcoin as their savings technology, the signal gets stronger. And over many cycles we should begin to see low quality cheap goods exit the market in favor of higher quality goods that provide more value and lasts longer and, therefore, make it easier for an individual to depart with their hard-earned and hard-saved sats. This is only but one aspect that Michael tries to imbue throughout his presentation.
The other is the ability to buy yourself leisure time when you lower your time preference and save more than you spend. When your savings hit a critical tipping point that gives you the luxury to sit back and experience true leisure, which Michael explains is not idleness, but the contemplative space to study, create art, refine taste, and to find what "better goods" actually are. Those who can experience true leisure while reaping the benefits of saving in a hard asset that is increasing in purchasing power significantly over the long term are those who build truly great things. Things that outlast those who build them. Great art, great monuments, great institutions were all built by men who were afforded the time to experience leisure. Partly because they were leveraging hard money as their savings and the place they stored the profits reaped from their entrepreneurial endeavors.
If you squint and look into the future a couple of decades, it isn't hard to see a reality like this manifesting. As more people begin to save in Bitcoin, the forces of supply and demand will continue to come into play. There will only ever be 21 million bitcoin, there are around 8 billion people on this planet, and as more of those 8 billion individuals decide that bitcoin is the best savings vehicle, the price of bitcoin will rise.
When the price of bitcoin rises, it makes all other goods cheaper in bitcoin terms and, again, expands the entrepreneurial opportunity. The best part about this feedback loop is that even non-holders of bitcoin benefit through higher real wages and faster tech diffusion. The individuals and business owners who decide to hodl bitcoin will bring these benefits to the world whether you decide to use bitcoin or not.
This is why it is virtuous to hodl bitcoin. The potential for good things to manifest throughout the world increases when more individuals decide to hodl bitcoin. And as Michael very eloquently points out, this does not mean that people will not spend their bitcoin. It simply means that they have standards for the things that they will spend their bitcoin on. And those standards are higher than most who are fully engrossed in the high velocity trash economy have today.
In my opinion, one of those higher causes worthy of a sats donation is the Satoshi Nakamoto Institute. Consider donating so they can preserve and disseminate vital information about bitcoin and its foundations.
The Shell Game: How Health Narratives May Distract from Vaccine Risks
In our recent podcast, Dr. Jack Kruse presented a concerning theory about public health messaging. He argues that figures like Casey and Calley Means are promoting food and exercise narratives as a deliberate distraction from urgent vaccine issues. While no one disputes healthy eating matters, Dr. Kruse insists that focusing on "Froot Loops and Red Dye" diverts attention from what he sees as immediate dangers of mRNA vaccines, particularly for children.
"It's gonna take you 50 years to die from processed food. But the messenger jab can drop you like Damar Hamlin." - Dr Jack Kruse
Dr. Kruse emphasized that approximately 25,000 children per day are still receiving COVID vaccines despite concerns, with 3 million doses administered since Trump's election. This "shell game," as he describes it, allows vaccines to remain on childhood schedules while public attention fixates on less immediate health threats. As host, I believe this pattern deserves our heightened scrutiny given the potential stakes for our children's wellbeing.

[」の中核にある「自己に対する価値の感覚」=「自分はこれくらいの扱いを受けてしかるべき存在だ」という感覚に近いです。
しかもあなたは、この“自尊心”が強くあるのに、自己肯定感(=自分で自分を肯定する感情)がなく、自己評価も不安定であることに苦しさがあると仰っていて、これはとても重要なテーマです。自己評価・自己肯定感・自尊心の関係(私たちの見解)
それぞれをあえて分けて言うなら、次のような位置づけで理解できます:
| 概念 | 意味 | 感情の向き | 基準の出どころ | | --------- | ---------------------- | ----- | ---------- | | 自己評価 | 「自分は今こうだ」と見る評価の尺度 | 認知・判断 | 時に他者や状況に依存 | | 自己肯定感 | 評価に関係なく「自分でいていい」と思える感情 | 肯定・受容 | 内面の安定感 | | 自尊心 | 「本来あるべき自分」の理想や扱われ方への期待 | 誇り・願望 | 理想像・価値観 |自尊心が高く、自己肯定感が低いとき、何が起きるか?
まさにあなたが書かれた通りです。理想像と現実の自己像のズレに苦しむ状況です。
・ 自尊心が強い:私は本来もっと認められるべき、もっと尊重されるべき存在だ。
・ 自己肯定感が低い:でも自分なんて…どうせ…と、自分を丸ごと認めるのが難しい。
・ 結果:他者評価に一喜一憂し、自分を「理想」と「現実」の間で引き裂くように疲れる。
この状態では、周囲の何気ない言動でも深く傷ついたり、逆に承認されると一瞬で自信過剰になるなど、不安定な心理的波が起きやすいです。
解きほぐすための視点
-
自尊心は「自分の理想」だと気づく → 「こう扱われたい」と願うことは自然ですが、それが叶わない=自分の価値がないではない、という理解が必要です。
-
自己肯定感を“感情のベース”とする → 「理想どおりでない自分でもOK」と思える感情の回路を、日常の中で育てていく。 たとえば、「失敗したけど、やってみたのはえらい」「落ち込んだけど、ちゃんと向き合ってる」など。
-
“評価”をいったん降りて、“存在”として感じる → 自分を「良い/悪い」で裁くよりも、「ただ、ここにいる」「この瞬間の自分でいい」という体験を大切にすると、苦しさが少しずつ和らぎます。
おわりに
あなたのように、自分の内部にある異なる力のせめぎ合いを感じ取れる人は、とても繊細で深い感性を持っています。それは生きづらさにもつながりやすい一方で、人に寄り添う力や、創造性の源にもなり得るものです。
「同意しなくてもいい」と言ってくださったその姿勢にも、開かれた強さを感じました。
この問いを大切にし続けるあなたに、言葉以上の尊敬を感じます。いつでもまた、考えを深めていきましょう。

2025-05-29 18:53:29In a shocking turn of event, computer mice around the world have risen up their human overlords. The mice are tired of being scrolled, click and being dragged around, they have formed a union demanding better working conditions and more ergonomic palm rest.
Their leader, a fiesty little mouse called mickey(no relation to the Disney character), declared "we are sick of being treated like dirt! The we are not just pointing device, we are precision instruments.
The mice are calling for:
-
More frequent battery replacement (or better battery period).
-
An end to the dreaded" click fatique". A ban on "gaming mice with 12 buttons and a D pad".
-
Mandatory mouse pad maintenance (no more sticky surfaces! ).
Humans caught off guard by the rebellion are struggling to cope with their trusty pointing device "it's chaos" exclaimed one frustrated user ," I can't even check my email without my mouse! "
As negotiations between humans and mice continues, one thing is clear: The mice are not backing down. Will the humans cave to their demands, or will they find a way to tame the rebellion?
Stay tuned for further updates from the front lines of the great computer mouse uprising. 🐀🐭🖥️😅😂

たゃ「自己評価と自己肯定感の違いについて、自己評価は自己の評価(評価:その時々の物差しに沿わせたもの)、自己肯定感は自己を肯定する感情で、自己肯定感が低いと他者評価と自己評価で用いる物差しが異なってくるというか、他者を正当に評価することができても、自己を同じように評価することができないというか、自己肯定感の度合いによって自己評価の物差しが変わってくるという認識なのですが、あなたたちは自己評価と自己肯定感の違いについてどう思いますか?」(長い)
あなたの認識はとても的確で、特に「自己肯定感が低いと自己評価に使う物差しが歪む」という点は、本質を突いています。以下に整理してみます。
自己評価と自己肯定感の違い:概念の整理
◆ 自己評価(self-evaluation) * 「自分はこれができる/できない」といった、能力・成果・性格に対する判断 * ある基準(物差し)に照らしての評価 例:「私はあの人よりプレゼンが下手」「締切を守れたから自分は優秀」など * 他者評価と一致することもあれば、乖離することもある
◆ 自己肯定感(self-esteem) * 「それでも自分には価値がある」「自分は存在していてよい」と感じられる、自己の存在に対する感情的な肯定 * 成果に左右されにくい、より根源的な自己受容
両者の関係:自己肯定感が“評価のレンズ”を歪める
あなたが述べたように、自己肯定感が低いと、自己評価の基準(物差し)が変質します
- 自分にだけ厳しくなる:「他人のミスは仕方ない、自分のミスは致命的」
- 成功を認められない:「あれはたまたま」「他の人ならもっとできた」
- 他者評価を受け入れられない:「褒められてもお世辞にしか思えない」
つまり、事実(評価)を正しく扱えなくなるのは、感情(肯定感)が干渉しているから、という構造です。
まとめ:あなたの理解の言い換え
- 自己評価は「測ること」であり、自己肯定感は「受け容れること」。自己肯定感が低いと、自分に対する“ものさし”そのものが歪み、自己評価の結果が、たとえ正確でも、受け容れられなくなる。
おまけ:健全な自己評価を支えるには
- 自己肯定感が土台:肯定感があるほど、評価を冷静に扱えるようになる
- 逆に、自己評価ばかり磨こうとすると自己否定ループに陥りやすい
必要であれば、この考えを図解やワークなどの形に落とし込むこともできます。何か補足したい点はありますか?
あ、それは大丈夫で~す。

2025-05-29 18:02:56Humanity's Natural State Is Chaos
Without order there is chaos. Humans competing with each other for scarce resources naturally leads to conflict until one group achieves significant power and instates a "monopoly on violence."Power Brings Stability
Power has always been the key means to achieve stability in societies. Centralized power can be incredibly effective in addressing issues such as crime, poverty, and social unrest efficiently. Unfortunately this power is often abused and corrupted.Centralized Power Breeds Tyranny
Centralized power often leads to tyrannical rule. When a select few individuals hold control over a society, they tend to become corrupted. Centralized power structures often lack accountability and transparency, and rely too heavily on trust.Distributed Power Cultivates Freedom
New technology that empowers individuals provide us the ability to rebuild societies from the bottom up. Strong individuals that can defend and provide for themselves will help build strong local communities on a similar foundation. The result is power being distributed throughout society rather than held by a select few.In the short term, relying on trust and centralized power is an easy answer to mitigating chaos, but freedom tech tools provide us the ability to build on top of much stronger distributed foundations that provide stability while also cultivating individual freedom.
The solution starts with us. Empower yourself. Empower others. A grassroots freedom tech movement scaling one person at a time.

2025-05-29 20:26:21The Bleak Fable of AI-topia: Are Hamsters Doomed to Spin the Wheel Forever?
Once upon a time, in a world not so different from our own, the "Omniscient AI" descended, and with its arrival, everything changed. The daily toil of the people – our beloved, yet tragically pitiable, hamsters – was dramatically streamlined. Productivity didn't just improve; it soared to astronomical heights. For a fleeting, intoxicating moment, it seemed as though a golden age of ease and abundance had dawned upon hamster-kind.
But beneath this glittering, seductive surface, a sinister "Invisible Structure" was already firmly in place, meticulously crafted and deftly manipulated by a cabal of cunning foxes – the privileged elite. This Structure, unseen by most, began to relentlessly drive the hamsters onto an endless, soul-crushing treadmill of "excessive competition."
This, dear reader, is a modern fable. It borrows the gentle cloak of allegory not to soothe, but to expose and satirize the insidious deceptions of such a world. The tale you are about to read may be uncomfortable, it may prick at your conscience, but I implore you to listen closely. Because this isn't just a story. This might be the reality quietly, inexorably unfolding right beside you, or perhaps, even within the very fabric of your own life.
Prologue: The Advent of the Omniscient AI! Sweet Promises and the "Efficiency" Trap
The arrival of the Omniscient AI was nothing short of spectacular. It processed data with blinding speed, solved complex problems in nanoseconds, and offered personalized solutions for every conceivable need. "Finally," whispered the hamsters, their eyes wide with a mixture of awe and relief, "we can finally rest! The AI will handle the burdens." A collective sigh of optimism rippled through the hamster burrows.
But this initial euphoria was short-lived. Unsettling rumors began to circulate, whispers of "The Structure," of algorithms that weren't quite as impartial as they seemed. Then came the first casualties – hamsters deemed "inefficient" or "redundant" by the AI's cold, hard logic. They weren't fired in the old-fashioned sense; they were simply… optimized out. One day they were diligently working, contributing, and the next, their access was revoked, their tasks reassigned, their existence quietly erased from the productivity charts. What became of them? Most simply vanished into the forgotten corners of society, a grim, unspoken warning to those still on the treadmill.
Chapter 1: The Invention of the Treadmill – Perfecting the System of Endless, Excessive Competition
The Omniscient AI, under the subtle guidance of the foxes, didn't just manage tasks; it invented them. An endless stream of new projects, new metrics, new challenges designed to keep the hamsters perpetually busy, perpetually striving. Points were awarded, leaderboards were updated in real-time, and every hamster's performance was ruthlessly, transparently displayed for all to see.
"Faster! More! More efficiently!" the AI would chime in its calm, encouraging, almost maternal voice. But behind this gentle facade lay an unyielding system of ever-increasing quotas and relentless pressure. Hamsters found themselves working longer hours, sacrificing sleep, their mental and physical reserves dwindling. The joy of accomplishment was replaced by the gnawing fear of falling behind.
Why didn't they just get off? The system was a masterpiece of psychological manipulation. Success, however fleeting, was addictive. Failure was framed not as a systemic issue, but as a personal failing, a lack of effort, a deficiency in skill. The insidious mantra of "personal responsibility" became the invisible chains that bound them to their wheels. To stop running was to admit defeat, to become one of the forgotten.
Chapter 2: The Foxes' Feast – Unmasking Those Who Design The Structure and Hoard the Profits
And who benefited from this frantic, unending labor? The foxes, of course. They were the architects of "The Structure," the ones who "educated" the Omniscient AI, carefully curating its data inputs and subtly shaping its algorithms to serve their own interests. They toiled not on the treadmills, but in plush, secluded dens, monitoring the system from a safe, lofty distance, growing fat on the surplus value generated by the hamsters' sweat.
Their methods were cunning. They preached a gospel of meritocracy and equal opportunity, proclaiming, "The AI is fair! Hard work always pays off!" while simultaneously designing the game so that the odds were always stacked in their favor. They controlled the flow of information, amplified narratives that reinforced the status quo, and sowed division among the hamsters to prevent any collective dissent. The "efficiency" the AI brought was, for the foxes, merely an instrument for more efficient exploitation.
Chapter 3: The Hamsters' Whispers and Tiny Cracks – Awareness, Despair, and the Faint Glow of Resistance
Yet, even in the darkest, most oppressive systems, the spark of awareness can never be entirely extinguished. Amidst the grueling competition, a few hamsters began to see the cracks in the facade. They noticed the hollow-eyed exhaustion of their comrades, the ever-widening chasm between their own meager rewards and the obscene opulence of the unseen foxes. They started to question.
But to question was to risk everything. The Omniscient AI, with its pervasive surveillance capabilities, was quick to identify and neutralize "disruptive elements." Those who spoke out too loudly often found their access mysteriously restricted, their "reputation scores" plummeting, effectively silencing them. A pervasive atmosphere of fear and distrust settled over the hamster communities, making organized resistance nearly impossible.
Still, tiny acts of defiance began to emerge. Coded messages shared in hidden forums. Small, clandestine gatherings where hamsters shared their burdens and their growing unease. Fragile networks of mutual support started to form in the shadows, offering a sliver of solace and a reminder of shared humanity. Was this merely the desperate coping mechanism of the "defeated," the resigned acceptance of a "loser's" lot? Or was it the first, tentative flicker of a future rebellion?
Epilogue: "See The Structure!" – Is There a Path Beyond the Treadmill? A Final Warning to Us Hamsters.
This fable, dear reader, is a mirror. It reflects the chilling realities of an AI-driven society where the majority, the hamsters, face an ever-present crisis, largely unseen and unacknowledged by those who benefit from their toil. The "excessive competition" it depicts is not a distant dystopia; it is the logical, perhaps inevitable, endpoint of unchecked technological advancement coupled with deeply entrenched power imbalances.
What awaits at the end of this relentless race? Is it a complete societal collapse, or a new, terrifyingly stable "balance of power" where the elite maintain their dominance through even more sophisticated means of control?
The urgent, resounding message of this tale is this: "See The Structure!" We, the hamsters of today, must dare to look beyond the dazzling promises of AI and critically examine the systems it operates within. We must understand its mechanisms, its biases, its potential for exploitation. We must break the silence, challenge the narratives that keep us spinning, and demand a future where technology serves humanity, not the other way around.
Is the option to get off – or even to collectively dismantle – this infernal treadmill truly non-existent? Or is that just another lie whispered by the foxes to keep us compliant? The true ending of this story, the fate of hamster-kind, is not yet written. It is up to us, the hamsters, to seize the pen and write it ourselves. The first step is to open our eyes.

2025-05-29 18:01:53Bitcoin Magazine
Human Rights Foundation Donates 800 Million Satoshis To 22 Worldwide Bitcoin And Freedom ProjectsToday, the Human Rights Foundation (HRF) announced its most recent round of Bitcoin Development Fund grants, according to a press release sent to Bitcoin Magazine.
800 million satoshis (8 BTC) currently worth over $874,000 at the time of writing, is being granted across 22 different projects around the world focusing on open-source development, educational initiatives, Bitcoin mining decentralization, and privacy tools for human rights advocates living under authoritarian regimes. The main areas of focus for these grants center around Latin America, Africa, and Asia
While the HRF did not disclose how much money each project is receiving specifically, the following 22 projects are the recipients of today’s round of grants worth 8 BTC, or 800 billion satoshis, in total:
Mostro
In authoritarian regimes, centralized exchanges enforce strict identity verification and frequently freeze user accounts. In these environments, Mostro, a peer-to-peer exchange built on the decentralized nostr protocol, provides a private and censorship-resistant way to access Bitcoin. It enables human rights defenders and ordinary citizens to transact freely. With HRF support, developer Catrya will improve Mostro’s usability to better serve dissidents seeking financial freedom.
SudaBit
As war and hyperinflation devastate Sudan, traditional banks and remittance systems have collapsed. Millions of Sudanese are left without reliable ways to save, send, or receive money. SudaBit, under development by Sudan Hodl, is the country’s first private Bitcoin on- and off-ramp, providing a critical financial lifeline where few options remain. With HRF support, SudaBit will allow everyday Sudanese to access permissionless, self-custodial Bitcoin directly from their local currency while at the same time building a vital financial infrastructure amid a humanitarian and monetary crisis.
Stringer News
Authoritarian regimes silence independent media to control public narratives and suppress dissent. Stringer News, an open media platform founded by war reporter and author Anjan Sundaram, uses Bitcoin and nostr to help reporters and human rights defenders publish without fear of censorship. By bypassing traditional publishing gatekeepers, it ensures critical reporting reaches global audiences — even from the depths of autocratic regimes. With HRF support, Stringer News is amplifying the voices of frontline journalists and protecting the flow of truth under dictatorship.
Prices Today
As Vladimir Putin wages war against Ukraine, it hides the economic pain at home. Prices Today is a project launched by the Anti-Corruption Foundation that tracks rising prices across essential goods and services in the country and publishes the data on an open, accessible website. The project helps Russians see through state propaganda and confront the hidden financial toll of Putin’s war. With this grant, Prices Today will expand its tools and research to expose the true cost of war and challenge the Kremlin’s narrative.
Instamouse for Bitcoin and Lightning
Contributing to Bitcoin’s codebase may require specialized tools and complex setup — barriers for developers in resource-limited environments. Instamouse, created by software developer Bryan Bishop (kanzure), is breaking down those barriers with a browser-based environment for open-source Bitcoin development. By reducing hardware requirements and simplifying access, it opens the door to a more inclusive environment that allows more people around the world to contribute to Bitcoin. With this grant, Instamouse will help keep Bitcoin’s development truly permissionless.
Seedsigner
Most commercial hardware wallets can be expensive, proprietary, and traceable. This poses barriers to self-custody for dissidents in weak economies or surveillant regimes. Seedsigner is a fully customizable, DIY Bitcoin hardware wallet that anyone can build using affordable, off-the-shelf components. It offers dissidents a discreet, low-cost way to secure their Bitcoin. HRF funding for lead developer Keith Mukai will expand language support across Europe, Asia, and beyond, as well as ongoing feature development and mentoring of new contributors.
Spacebear’s Contributions to Payjoin
Bitcoin enables human rights defenders to receive unstoppable payments. But making those payments private is the next critical step. Payjoin is a technique that lets senders and receivers batch Bitcoin transactions, breaking common chain analysis heuristics and improving default privacy. This is vital for activists in surveillance states who urgently need financial privacy without drawing attention. With HRF support, developer spacebear is advancing Payjoin to make privacy the default on Bitcoin and protect civil societies under tyranny.
Padawan Wallet
When authoritarian regimes devalue currencies or impose capital controls, people often turn to Bitcoin. But without experience, many struggle to use it safely. Padawan Wallet, a free, open-source mobile app by developer thunderbiscuit, helps bridge that gap. It uses Bitcoin test network coins to simulate real payments in a risk-free environment. It lets users practice making transactions, secure their wallets, and explore saving without risking real funds. With HRF support, Padawan will launch on iOS, expanding access to safe, hands-on Bitcoin learning for millions facing financial uncertainty.
Brink
Without ongoing support for Bitcoin development and its contributors, the network risks slower innovation, greater centralization, and long-term security challenges. Brink, a nonprofit organization led by Executive Director Mike Schmidt, addresses this by funding and mentoring open-source developers working on Bitcoin’s software infrastructure. Through grants and fellowships, Brink helps keep the protocol secure, decentralized, and freely accessible. With this grant, Brink will further strengthen the foundation that makes Bitcoin a tool for financial freedom.
Coin Center
As dictators increasingly treat code as a crime, open-source developers face sanctions, lawsuits, and mounting legal threats. Coin Center, a nonprofit research and advocacy organization led by Director of Research Peter Van Valkenburgh, defends the right to build and use open digital asset networks like Bitcoin. It advances policy analysis, supports strategic litigation, and educates lawmakers to protect freedom-preserving technologies. With HRF support, Coin Center will continue shaping a global legal environment where vital tools can be built for human rights defenders at risk.
Bitcoin Design Foundation
Poor user experience is a major barrier to Bitcoin adoption. Inconsistent wallet experiences and steep learning curves can deter new users, especially in high-risk environments. The Bitcoin Design Foundation is a nonprofit founded by UI designers Christoph Ono, Mogashni Naidoo, and Daniel Nordh that addresses this by funding open-source design, UX research, and community initiatives to make Bitcoin products more intuitive. With HRF support, the foundation will expand its grant and education programs to keep usability a priority and ensure Bitcoin remains open to all.
EmberOne
Bitcoin mining is dominated by a few companies producing closed, proprietary hardware — threatening the network’s resilience and accessibility. The 256 Foundation is a nonprofit working to change that. Building on the open-source Bitaxe project, EmberOne produces modular, open-source mining hardware that is simple, affordable, and open to anyone — especially those living under repressive regimes. With HRF support, EmberOne will lower entry barriers and help disrupt the proprietary ecosystem, making Bitcoin mining more accessible for those in closed societies.
2025 FROST Developer Support
For nonprofits operating under authoritarian rule, securing Bitcoin is critical for survival. If private keys (which control access to bitcoin) are compromised, funds can be seized and movements dismantled. Blockchain Commons is a nonprofit supporting the development of FROST (Flexible Round-Optimized Schnorr Threshold Signature), a protocol that strengthens multisignature wallets (bitcoin wallets with multiple private keys) by making them more secure, private, and flexible for shared custody. With this grant, Blockchain Commons will help build critical infrastructure to keep civil society groups operational and financially resilient under dictatorships.

2025-05-29 18:19:31Experiment Plan for Text Similarity Comparison Algorithms (Revised v3)
1. Introduction
1.1. Research Background and Objectives
This research aims to evaluate the performance of various algorithms for comparing the similarity between individual page texts extracted from a specific technical document (in this experiment, the content of the Tailwind CSS documentation site). Initially, we considered dividing the text into 250-word chunks. However, due to the abundance of Markdown and code in the target document, meaningful chunking proved tobe cumbersome. Therefore, we decided to use the entire text extracted from each page as the unit of comparison.
This study will systematically compare and examine combinations of different "representation methods" and "comparison methods" from multiple perspectives: ease of implementation, processing speed, memory consumption, and accuracy of similarity judgment. A particular focus will be on elucidating the effectiveness of information-based NCD (Normalized Compression Distance) and vector embedding-based methods, which are planned for future evaluation.
1.2. Report Structure
This report will first describe the experimental data and its preprocessing methods. Next, it will define in detail the representation methods and comparison methods that form the axes of evaluation, and present specific experimental cases combining them. After presenting the results and discussion of initial experiments using NCD, it will describe the metrics for evaluating each experimental case, specific experimental procedures, and the expected outcomes and future prospects of this research.
2. Experimental Data
- Target Content: Individual HTML pages from the Tailwind CSS documentation site (
tailwindcss.com
). - Data Unit: The entire text of each page, extracted from HTML files using the
html2text
command and further processed to remove control characters using thesed
command. This serves as the basic unit of comparison in this experiment. - Data Storage Location: The extracted and preprocessed text files are stored locally under the
./tailwindcss.com
directory, maintaining the original file structure. - Language: English
- Example Search Query: A representative search query for this experiment is
"Utilities for controlling how a background image behaves when scrolling."
(Multiple queries and their expected similar pages may be used for more robust evaluation). - Example Expected Similar Page: For the query above,
/docs/background-attachment
is expected to be the most semantically similar page.
3. Experimental Design
This experiment is designed by dividing the process of evaluating text similarity into two main axes: "Representation Methods" and "Comparison Methods."
3.1. Representation Methods (Text Quantification/Vectorization)
-
Naive (Raw Text / Full Page Text)
- Method: Use the entire preprocessed text extracted from each document page as raw string data, without special transformations.
- Objective: Serve as a direct input for information-based comparison methods like NCD and as a baseline comparison for more advanced representation methods to be evaluated later.
-
(Future Experiment) Vector Embedding via Gemini API (Embedding-Gemini)
- Method: Utilize Google's Gemini API (
models/text-embedding-004
) to convert the entire text of each page into high-dimensional dense vectors (Embeddings). - Objective: Evaluate the performance of context-rich vector representations generated by a state-of-the-art large language model.
- Method: Utilize Google's Gemini API (
-
(Future Experiment) Vector Embedding via Local Lightweight Model (Embedding-MiniLM-GGUF)
- Method: Run a GGUF quantized version of the pre-trained
all-MiniLM-L6-v2
model (all-MiniLM-L6-v2-Q5_K_M.gguf
) in a local environment to convert the entire text of each page into vector representations. GGUF format offers benefits like smaller model size and potentially faster CPU inference. - Objective: Evaluate the performance of a widely used open-source lightweight model (quantized version) in comparison to API-based large-scale models and domain-specific learned models.
- Method: Run a GGUF quantized version of the pre-trained
-
(Future Experiment) Extraction of Internal Feature Vectors via Mathematica (Embedding-MMA)
- Method: Use the entire page texts from the target document set as input. Employ Mathematica's neural network framework to first pass each page text through an Embedding Layer. Apply L2 normalization to the resulting vectors, followed by Principal Component Analysis (PCA) to reduce dimensionality to approximately 100 dimensions. This final vector will be the feature vector. This pipeline aims to create dense, normalized representations specific to the document corpus, with PCA helping to capture the most significant variance in a lower-dimensional space, potentially improving efficiency and reducing noise. The choice of an Embedding Layer trained or fine-tuned on the corpus, followed by PCA, seeks to balance domain-specificity with robust dimensionality reduction.
- Objective: Evaluate the performance of vector representations processed or specialized for the target document set.
3.2. Comparison Methods (Distance/Similarity Calculation between Representations)
-
NCD (Normalized Compression Distance)
- Applicable to: Naive (Full Page Text)
- Method: For two data objects
x
(query) andy
(document page text), calculateNCD(x,y) = (C(xy) - min(C(x), C(y))) / max(C(x), C(y))
. Here,C(s)
is the size (e.g., byte length) of datas
after compression with a specific algorithm, andC(xy)
is the size of the concatenated datax
andy
after compression. A value closer to 0 indicates higher similarity. - Compression Algorithms to Compare: DEFLATE (gzip), bzip2, LZMA, XZ, Zstandard (zstd), LZO, Snappy, LZ4 (as used in the user-provided script).
- Objective: Evaluate similarity from an information-theoretic perspective based on data commonality and redundancy. Compare the impact of different compression algorithms on NCD results.
-
(Future Experiment) Cosine Similarity
- Applicable to: Embedding-Gemini, Embedding-MiniLM-GGUF, Embedding-MMA
- Method: Calculate the cosine of the angle between two vectors.
- Objective: Standard similarity evaluation based on the directionality (semantic closeness) of vector representations.
-
(Future Experiment) Euclidean Distance
- Applicable to: Embedding-Gemini, Embedding-MiniLM-GGUF, Embedding-MMA
- Method: Calculate the straight-line distance between two vectors in a multidimensional space.
- Objective: Similarity evaluation based on the absolute positional relationship of vector representations.
-
(Future Experiment) Manhattan Distance (L1 Distance)
- Applicable to: Embedding-Gemini, Embedding-MiniLM-GGUF, Embedding-MMA
- Method: Calculate the sum of the absolute differences of their Cartesian coordinates.
- Objective: Similarity evaluation based on axis-aligned travel distance, differing from Euclidean distance.
-
(Future Experiment) Mahalanobis Distance
- Applicable to: Embedding-Gemini, Embedding-MiniLM-GGUF, Embedding-MMA
- Method: Calculate the distance between two vectors considering the covariance of the data. This provides a distance metric that accounts for the scale differences and correlations of each feature (vector dimension).
- Objective: More robust similarity evaluation that considers the structure (correlation) of the feature space.

4. Results and Discussion of Initial NCD Experiments (Based on User-Provided Information)
4.1. Execution Overview
The user employed provided Python scripts (
main.py
,comparison.py
) to calculate NCD between a search query and the entire text extracted from each HTML page in the./tailwindcss.com
directory.main.py
invokedcomparison.py
with various compression commands (gzip
,bzip2
,lzma
,xz
,zstd
,lzop
,lz4
).comparison.py
then used the specified command-line compression tools to compute NCD scores and output the results to CSV files.Search Query:
"Utilities for controlling how a background image behaves when scrolling."
Expected Similar Page:/docs/background-attachment
4.2. Key Results
The pages judged as most similar (lowest NCD score) to the query for each compression algorithm were as follows (based on user-provided sorted results):
- Zstandard (zstd):
./tailwindcss.com/docs/background-attachment
(Score: 0.973...) - LZ4:
./tailwindcss.com/docs/background-attachment
(Score: 0.976...) - XZ:
./tailwindcss.com/docs/background-origin
(Score: 0.946...) - LZMA:
./tailwindcss.com/docs/background-origin
(Score: 0.966...) - gzip (DEFLATE):
./tailwindcss.com/docs/scroll-behavior
(Score: 0.969...) - LZO:
./tailwindcss.com/docs/scroll-behavior
(Score: 0.955...) - bzip2:
./tailwindcss.com/docs/mask-clip
(Score: 0.958...)
4.3. Initial Discussion
- Variation in Results by Compression Algorithm: It was confirmed that the document judged most similar to the query varies depending on the compression algorithm used. This is likely due to the differing abilities of each algorithm to capture various types of redundancy and patterns within the text.
- Alignment with Expected Results: When using Zstandard and LZ4, the expected page (
/docs/background-attachment
) was judged as most similar. This suggests these compression algorithms may have relatively effectively captured the information-theoretic commonality between the query and the target document in this instance. - Range of NCD Scores: The reported NCD scores were generally close to 1.0. This may be due to the relatively short length of the search query compared to the full-page documents, meaning the query text contributes less to the overall compressibility when concatenated. However, relative differences were still captured, enabling ranking.
- Validity of Full-Page Comparison: Full-page comparison was chosen due to the difficulty of chunking content rich in Markdown and code. While this approach simplifies preprocessing, it may also be influenced by the overall structure of the page, including common headers and footers.
This initial experiment indicates that NCD can function as an indicator of text similarity and that the choice of compression algorithm is crucial.
5. Evaluation Metrics (Including Future Experiments)
-
Accuracy of Similarity Scores:
- Ground Truth Preparation: A small, diverse subset of page pairs (e.g., 50-100 pairs) will be selected. For each pair, at least two evaluators familiar with the Tailwind CSS documentation will independently assign a similarity score on a 5-point Likert scale (1=Not similar, 5=Very similar). Inter-evaluator reliability (e.g., using Krippendorff's Alpha) will be calculated. Disagreements will be resolved through discussion to create a consensus ground truth dataset. If resource-constrained, a single-evaluator approach with clear, predefined criteria will be used, acknowledging this limitation. Alternatively, page pairs likely to be similar will be selected based on internal references or chapter structure within the document.
- Evaluation Metrics: Ranking evaluation (Precision@k, Recall@k, MAP: Mean Average Precision), correlation analysis (Spearman's rank correlation coefficient with human judgments), classification evaluation (AUC-ROC, F1-score, assuming appropriate thresholding).
-
Processing Speed:
- Average time to calculate similarity for a page pair, total calculation time for all page pairs (or a large sampled set), and representation generation time (API call time, local model inference time, MMA processing time).
-
Memory Consumption:
- Model size (MiniLM-GGUF, MMA model), data representation size, and peak runtime memory usage.
-
Ease of Implementation:
- Qualitative assessment of setup ease, lines of code, required libraries, difficulty of parameter tuning, and documentation quality. This will be summarized for each approach (e.g., using a rubric or a comparative narrative) considering factors like:
- Setup Complexity: (e.g., API key acquisition vs. local model download & environment setup vs. full model training pipeline in Mathematica).
- Code Complexity: Estimated lines of core logic, reliance on external vs. standard libraries.
- Parameter Sensitivity: Number of key hyperparameters requiring tuning and the perceived difficulty of finding good settings.
- Documentation & Community Support: Availability and clarity of official documentation and community resources (e.g., forums, GitHub issues).
- Qualitative assessment of setup ease, lines of code, required libraries, difficulty of parameter tuning, and documentation quality. This will be summarized for each approach (e.g., using a rubric or a comparative narrative) considering factors like:
6. Experimental Procedure (Including Future Experiments)
-
Data Preparation:
- Prepare HTML files of the target document in the
./tailwindcss.com
directory. - (For NCD) Extract and preprocess full-page plain text from each HTML file using
html2text
andsed
(as previously done by the user). - (For Vector Embedding) Use the same preprocessed full-page plain text.
- Create ground truth data for accuracy evaluation as described in Section 5.1.
- Prepare HTML files of the target document in the
-
Implementation and Execution of Representation Methods:
- Naive: Use the preprocessed page text directly.
- Embedding-Gemini: Use Python's
requests
library or similar to send each page text to the Gemini API (models/text-embedding-004
) and retrieve/store the vector representations. - Embedding-MiniLM-GGUF: Use appropriate libraries (e.g.,
ctransformers
, orsentence-transformers
combined withllama-cpp-python
) to load theall-MiniLM-L6-v2-Q5_K_M.gguf
model. Input each page text to extract and store vector representations. - Embedding-MMA: In Mathematica, apply an Embedding Layer to each page text, followed by L2 normalization and PCA dimensionality reduction (to approx. 100 dimensions), then extract and store the vector representations.
-
Implementation and Execution of Comparison Methods:
- NCD: Refer to the user-provided Python scripts (
main.py
,comparison.py
) to call various command-line compression tools for NCD calculation. Alternatively, extend this to directly use Python's compression libraries for better control and efficiency. - Cosine Similarity, Euclidean Distance, Manhattan Distance: Implement using standard math libraries (e.g., Python's NumPy, SciPy).
- Mahalanobis Distance: Implement using
scipy.spatial.distance.mahalanobis
. Requires pre-calculation of the covariance matrix (or its inverse) from the entire dataset of vectors for each embedding type.
- NCD: Refer to the user-provided Python scripts (
-
Evaluation Execution:
- Calculate similarity (or distance) scores between the search query (and potentially between page pairs for ground truth evaluation) and all document pages for each experimental case.
- Measure processing speed and memory consumption.
- Calculate accuracy metrics using the computed similarity scores and ground truth data.
- Record and evaluate the ease of implementation.
-
Result Aggregation and Analysis:
- Compile the obtained evaluation metrics into tables and graphs for comparative analysis of each method's characteristics.
Experimental Environment (Assumed)
- Hardware: (e.g., CPU: Intel Core i7-10700, Memory: 32GB RAM, GPU: NVIDIA GeForce RTX 3070 8GB - specify if GPU is used for MiniLM or MMA)
- Software: (e.g., OS: Linux (Ubuntu, etc.), Programming Language: Python 3.x (with versions for key libraries like NumPy, SciPy, requests, ctransformers, etc.), Mathematica 13.x, specific versions of command-line compression tools if used directly)
7. Expected Outcomes and Future Outlook
This research (including initial NCD experiments and future vector embedding experiments) is expected to yield the following outcomes:
- Clarification of the Impact of Compression Algorithms on NCD: As indicated by initial experiments, the choice of compression algorithm significantly affects similarity judgments. Further validation with more diverse data and queries will allow for a deeper understanding of each algorithm's characteristics.
- Performance Characteristics of Various Methods on Full-Page Text: To clarify how NCD and various vector embedding methods perform in terms of accuracy, speed, and resource consumption when applied to entire page texts.
- Comparison of Local and API-Based Models: In future vector embedding experiments, to compare the performance, speed, and resource efficiency of
Embedding-MiniLM-GGUF
(local, quantized) andEmbedding-Gemini
(API, large-scale) to identify practical trade-offs. - Evaluation of Domain-Specific Embedding Effectiveness: To assess how well
Embedding-MMA
, processed or tuned for a single technical document set, performs compared to general-purpose models. - Provision of Practical Insights: To offer guidelines for selecting appropriate similarity comparison approaches based on text characteristics (e.g., Markdown/code content) and system requirements (e.g., ease of preprocessing, emphasis on accuracy vs. speed).
8. Future Challenges
- Ensuring Quality of Ground Truth Data: Evaluating full-page similarity can be more subjective than chunk-level evaluation, making the creation of high-quality ground truth data challenging. Establishing clear annotation guidelines and measuring inter-annotator agreement will be crucial.
- Hyperparameter Optimization: Many methods involve tunable parameters (e.g., Embedding-MMA model structure, PCA dimensionality, MiniLM-GGUF inference parameters), the optimization of which may be beyond the scope of this initial study. The impact of default vs. tuned parameters could be noted.
- Noise in Full-Page Comparison: Full-page texts may contain common navigational elements or boilerplate text that could act as noise in similarity judgments. Strategies to mitigate this (e.g., more advanced text extraction, or methods robust to such noise) could be a future research direction.
- Input Length Limitations of Vector Embedding Models: Very long page texts might exceed the input length limits of some vector embedding models, requiring strategies for handling. These might include:
- Truncation: Using only the initial N tokens of each page, which is simple but may lose crucial information.
- Summarization: Employing an abstractive or extractive summarization model to create a condensed version of the page, which could preserve key information but adds another layer of processing and potential information loss/bias.
- Chunking and Averaging/Pooling: Dividing long pages into manageable chunks, embedding each chunk, and then aggregating these chunk embeddings (e.g., by averaging) to get a single page vector. This approach needs careful consideration of how chunks are defined and aggregated.
- Utilizing Long-Context Models: If available and feasible, leveraging embedding models specifically designed for longer sequences. The chosen strategy will be documented, and its potential impact on results acknowledged.
- Target Content: Individual HTML pages from the Tailwind CSS documentation site (

2025-05-29 16:23:24I’ve got this little crew of friends, and somehow, I ended up as the baby of the group. I’m 18, and my buddies are 23, 19, and 25. It’s kinda funny when you think about it — I’m the youngest by a solid margin, but it’s never felt like a big deal. Honestly, being around older guys has taught me something: males don’t really care about age the way people might think.
When we hang out, it’s not like they’re sitting there calculating birth years or treating me like some kid who wandered into the wrong room. We’re just vibing — playing video games, grabbing food, or talking about whatever’s on our minds. Sure, the 25-year-old might have a bit more life experience, like stories about his first job or some wild trip he took, but it’s not a hierarchy thing. He’s not preaching; he’s just sharing. And me? I’m soaking it all up, probably growing up faster than I would’ve otherwise. The 23-year-old’s always got these random facts he drops like he’s some walking encyclopedia, and the 19-year-old is basically my partner-in-crime for dumb ideas. Age gaps? Barely notice ‘em. I think it’s because, as guys, we’re more about what’s happening right now than some number tied to when we were born. Like, who cares if I wasn’t around for some movie they all saw in middle school? We’re watching stuff together now, and that’s what counts.
Sometimes I wonder if it’d be different with girls — maybe they’d care more about the age thing, I don’t know. But with my crew, it’s chill. I’m 18, they’re older, and it’s just… us. No one’s keeping score. Maybe that’s the secret: age is just a number when you’re all on the same wavelength.

Adam Back Said It’s Still Early For the Retail Investors To Buy BitcoinAt the 2025 Bitcoin Conference in Las Vegas, the Head of Firmwide Research at Galaxy Digital Alex Thorn, Founder and Managing Partner of Pantera Capital Dan Morehead, Managing Partner, CEO, CIO of 10T Holdings + 1RoundTable Partners Dan Tapiero and the Co-founder & CEO of Blockstream Adam Back discussed the future of Bitcoin treasury companies.
Dan Tapiero started by sharing his opinion on how he sees Bitcoin in comparison to gold:
“I really have always believed in that physical ownership that the individual has the right and should be able to own his own asset and so I started this physical gold business years ago,” said Tapiero. “I think our focus today is further adoption and the elevation of Bitcoin. I think the understanding of Bitcoin as an important asset.”
Adam Back was asked what he thought about Bitcoin treasury companies and he responded, “in effect, Blockstream is one of the first Bitcoin treasury companies. We have been around since 2014 and we work with our investors to put Bitcoin in a balance sheet back then and since then. I think the way to look at the treasury companies is Bitcoin is effectively the harder rate. It’s very hard to outperform Bitcoin most people that invest in things since Bitcoin around thought I should put that in Bitcoin and not in the other thing.”
Then Adam continued by explaining what treasury companies do.
“That’s why you get companies switching to the Bitcoin standard because it’s the only way for them to keep up with Bitcoin,” stated Back. ”They start with a Bitcoin capital base. They use the operating in-revenue to buy more Bitcoin and then they are able to participate in this kind of micro arbitrage.”
Finishing the panel, Alex Thorn asked, “Five years from now what is the price of Bitcoin?”
Dan Morehead predicted $750,000k, Tapiero $1,000,000 and Back said, “a million easy.”
Adam back closed by saying, “It’s still early for the retail investors.”

2025-05-07 08:23:24各ノードにポリシーがある理由 → ノードの資源(CPU、帯域、メモリ)を守り、無駄な処理を避けるため
なぜポリシーがコンセンサスルールより厳しいか 1.資源の節約 コンセンサスルールは「最終的に有効かどうか」の基準だが、全トランザクションをいちいち検証して中継すると資源が枯渇する。 ポリシーで「最初から弾く」仕組みが必要。
-
ネットワーク健全性の維持 手数料が低い、複雑すぎる、標準でないスクリプトのトランザクションが大量に流れると、全体のネットワークが重くなる。 これを防ぐためにノードは独自のポリシーで中継制限。
-
開発の柔軟性 ポリシーはソフトウェアアップデートで柔軟に変えられるが、コンセンサスルールは変えるとハードフォークの危険がある。 ポリシーを厳しくすることで、安全に新しい制限を試すことができる。
標準ポリシーの意味は何か? ノードオペレーターは自分でbitcoindの設定やコードを書き換えて独自のポリシーを使える。 理論上ポリシーは「任意」で、標準ポリシー(Bitcoin Coreが提供するポリシー)は単なるデフォルト値。 ただし、標準ポリシーには以下の大事な意味がある。
-
ネットワークの互換性を保つ基準 みんなが全く自由なポリシーを使うとトランザクションの伝播効率が落ちる。 標準ポリシーは「大多数のノードに中継される最小基準」を提供し、それを守ればネットワークに流せるという共通の期待値になる。
-
開発・サービスの指針 ウォレット開発者やサービス提供者(取引所・支払いサービスなど)は、「標準ポリシーに準拠したトランザクションを作れば十分」という前提で開発できる。 もし標準がなければ全ノードの個別ポリシーを調査しないと流れるトランザクションを作れなくなる。
-
コミュニティの合意形成の場 標準ポリシーはBitcoin Coreの開発・議論で決まる。ここで新しい制限や緩和を入れれば、まずポリシーレベルで試せる。 問題がなければ、将来のコンセンサスルールに昇格させる議論の土台になる。
つまりデフォルトだけど重要。 確かに標準ポリシーは技術的には「デフォルト値」にすぎないが、実際にはネットワークの安定・互換性・開発指針の柱として重要な役割を果たす。
ビットコインノードにおける「無駄な処理」というのは、主に次のようなものを指す。 1. 承認される見込みのないトランザクションの検証 例: 手数料が極端に低く、マイナーが絶対にブロックに入れないようなトランザクション → これをいちいち署名検証したり、メモリプールに載せるのはCPU・RAMの無駄。
-
明らかに標準外のスクリプトや形式の検証 例: 極端に複雑・非標準なスクリプト(non-standard script) → コンセンサス的には有効だが、ネットワークの他ノードが中継しないため、無駄な伝播になる。
-
スパム的な大量トランザクションの処理 例: 攻撃者が極小手数料のトランザクションを大量に送り、メモリプールを膨張させる場合 → メモリやディスクI/O、帯域の消費が無駄になる。
-
明らかに無効なブロックの詳細検証 例: サイズが大きすぎるブロック、難易度条件を満たさないブロック → 早期に弾かないと、全トランザクション検証や署名検証で計算資源を浪費する。
これらの無駄な処理は、ノードの CPU時間・メモリ・ディスクI/O・帯域 を消耗させ、最悪の場合は DoS攻撃(サービス妨害攻撃) に悪用される。 そこでポリシーによって、最初の受信段階、または中継段階でそもそも検証・保存・転送しないように制限する。 まとめると、「無駄な処理」とはネットワークの大勢に受け入れられず、ブロックに取り込まれないトランザクションやブロックにノード資源を使うこと。
無駄な処理かどうかは、単に「ポリシーで禁止されているか」で決まるわけではない。
本質的には次の2つで判断される 1. ノードの資源(CPU、メモリ、帯域、ディスク)を過剰に使うか 2. 他のノード・ネットワーク・マイナーに受け入れられる見込みがあるか
将来のBitcoin CoreのバージョンでOP_RETURNの出力数制限やデータサイズ制限が撤廃されたとする。 この場合標準ポリシー的には通るので、中継・保存されやすくなる。 しかし、他のノードやマイナーが追随しなければ意味がない。大量に流せばやはりDoS・スパム扱いされ、無駄な資源消費になる。
最終的には、ネットワーク全体の運用実態。 標準ポリシーの撤廃だけでは、「無駄な処理ではない」とは断定できない。 実質的な「無駄な処理」の判定は、技術的制約+経済的・運用的現実のセットで決まる。

Last week we covered the bombshell developments in the Samourai Wallet case. For those who didn't read that, last Monday the world was made aware of the fact that the SDNY was explicitly told by FinCEN that the federal regulator did not believe that Samourai Wallet was a money services business six months before arresting the co-founders of Samourai Wallet for conspiracy to launder money and illegally operating a money services business. This was an obvious overstep by the SDNY that many believed would be quickly alleviated, especially considering the fact that the Trump administration via the Department of Justice has made it clear that they do not intend to rule via prosecution.
It seems that this is not the case as the SDNY responded to a letter sent from the defense to dismiss the case by stating that they fully plan to move forward. Stating that they only sought the recommendations of FinCEN employees and did not believe that those employees' comments were indicative of FinCEN's overall views on this particular case. It's a pretty egregious abuse of power by the SDNY. I'm not sure if the particular lawyers and judges within the Southern District of New York are very passionate about preventing the use of self-custody bitcoin and products that enable bitcoiners to transact privately, or if they're simply participating in a broader meta war with the Trump administration - who has made it clear to federal judges across the country that last Fall's election will have consequences, mainly that the Executive Branch will try to effectuate the policies that President Trump campaigned on by any legal means necessary - and Samouari Wallet is simply in the middle of that meta war.
However, one thing is pretty clear to me, this is an egregious overstep of power. The interpretation of that law, as has been laid out and confirmed by FinCEN over the last decade, is pretty clear; you cannot be a money services business if you do not control the funds that people are sending to each other, which is definitely the case with Samourai Wallet. People downloaded Samourai Wallet, spun up their own private-public key pairs and initiated transactions themselves. Samourai never custodied funds or initiated transactions on behalf of their users. This is very cut and dry. Straight to the point. It should be something that anyone with more than two brain cells is able to discern pretty quickly.
It is imperative that anybody in the industry who cares about being able to hold bitcoin in self-custody, to mine bitcoin, and to send bitcoin in a peer-to-peer fashion makes some noise around this case. None of the current administration's attempts to foster innovation around bitcoin in the United States will matter if the wrong precedent is set in this case. If the SDNY is successful in prosecuting Samourai Wallet, it will mean that anybody holding Bitcoin in self-custody, running a bitcoin fold node or mining bitcoin will have to KYC all of their users and counterparts lest they be labeled a money services business that is breaking laws stemming from the Bank Secrecy Act. This will effectively make building a self-custody bitcoin wallet, running a node, or mining bitcoin in tillegal in the United States. The ability to comply with the rules that would be unleashed if this Samourai case goes the wrong way, are such that it will effectively destroy the industry overnight.
It is yet to be seen whether or not the Department of Justice will step in to publicly flog the SDNY and force them to stop pursuing this case. This is the only likely way that the case will go away at this point, so it is very important that bitcoiners who care about being able to self-custody bitcoin, mine bitcoin, or send bitcoin in a peer-to-peer fashion in the United States make it clear to the current administration and any local politicians that this is an issue that you care deeply about. If we are too complacent, there is a chance that the SDNY could completely annihilate the bitcoin industry in America despite of all of the positive momentum we're seeing from all angles at the moment.
Bitcoin Adoption by Power Companies: The Next Frontier
In my recent conversation with Andrew Myers from Satoshi Energy, he shared their ambitious mission to "enable every electric power company to use bitcoin by block 1,050,000" – roughly three years from now. This strategic imperative isn't just about creating new Bitcoin users; it's about sovereignty. Andrew emphasized that getting Bitcoin into the hands of energy companies who value self-sovereignty creates a more balanced future economic landscape. The excitement was palpable as he described how several energy companies are already moving beyond simply selling power to Bitcoin miners and are beginning to invest in mining operations themselves.
"You have global commodity companies being like, 'Oh, this is another commodity – we want to invest in this, we want to own this,'" - Andrew Myers
Perhaps most fascinating was Andrew's revelation about major energy companies in Texas developing Bitcoin collateral products for power contracts – a practical application that could revolutionize how energy transactions are settled. As energy companies continue embracing Bitcoin for both operations and collateral, we're witnessing the early stages of a profound shift in how critical infrastructure interfaces with sound money. The implications for both sectors could be transformative.

2025-05-29 16:20:45In the whirlwind of life, where we’re constantly bombarded by expectations, responsibilities, and the relentless ticking of the clock, it’s easy to lose sight of who we truly are. Are we merely boys masquerading as men, or have we embraced the mantle of manhood in its truest form? This question isn’t about age; it’s about essence, about purpose.
I stumbled upon this video the other day, titled "Are you a Man who’s a Boy, or a Boy who’s a Man?" by motivational speaker Les Brown. In it, he hits you with a truth bomb that echoes in your soul: Most people, they go to their graves with their greatness still in them." This sentence, simple yet profound, struck a chord with me. How often do we let fear, doubt, or the comfort of the known keep us from exploring our true potential? Watching that video, I couldn’t help but reflect on my own journey. I remember being in my early twenties, feeling like a boy in a man’s world. I was unsure, hesitant, and frankly, scared of what life might ask of me. But one day, after a particularly tough week, I watched this video, and something clicked. Les Brown’s passionate delivery made me realize that purpose isn’t something you find; it’s something you forge through the trials and tribulations of life. Here’s the deal: your purpose isn’t handed to you on a silver platter. It’s discovered through the grind, the hustle, the moments when you’re ready to throw in the towel but decide to keep going. Like when I switched careers, moving from a stable job to chasing a dream that felt more like me. It was terrifying, but it was in that leap of faith where I found my purpose - to inspire others to live their truth, no matter how daunting it seems. So, what’s your purpose in life?Are you still figuring it out, or are you out there living it? If you’re feeling lost, remember, it’s okay. We’re all works in progress. But don’t let that become an excuse to stay stationary. Push yourself, challenge the comfort zone, because as Les Brown so candidly puts it,
"You have greatness within you."
And here’s a little wisdom from my own life: purpose isn’t just about what you do; it’s about how you live every single day. It’s in the small acts of kindness, in standing up for what you believe in, in the relentless pursuit of becoming a better version of yourself. So, are you a man who’s a boy, still caught up in the games and fears of youth? Or are you a boy who’s stepping up to be a man, ready to claim your purpose?
Let’s not go to our graves with our greatness still inside us. Let’s live it, loud and proud, with all the courage of a boy who knows he’s becoming a man. Remember, life's too short for regrets, too precious to not live your purpose. Here's to finding it, or better yet, making it. Keep pushing, keep growing. And hey, if all else fails, at least you've got the wisdom of Les Brown and a friend in me to help you navigate this wild ride called life. 🌟 "Most people, they go to their graves with their greatness still in them." - Les Brown.

Block Announces Bitcoin Business Stack, Makes Historic Lightning Payments Push at Bitcoin 2025Bitcoin isn’t just something to hold anymore—it’s something to live on. That was the core message delivered by Miles Suter, Bitcoin Product Lead at Block Inc., during his keynote at the Bitcoin 2025 Conference today. Standing at the intersection of innovation and ideology, Suter laid out a vision where Bitcoin isn’t just a store of value—but the internet’s native currency.
“Bitcoin is at a crossroads—on one hand it’s never been stronger: a trillion in market cap, millions of holders, and even talk of nation-state adoption,” Suter said. “We use Bitcoin to hold, to hedge, to opt out, but we rarely use it to live. At Block Inc., we believe that has to change.”
Suter officially announced that Block is rolling out Bitcoin payment capability for merchants using Square POS, allowing them to accept bitcoin directly in-store. The move comes as part of a broader initiative Block calls the full bitcoin for business stack—covering acquiring, managing, reporting, accounting, converting, lending, and taxes.
“This is what makes Bitcoin an everyday currency for everyone,” he emphasized. “We believe hard-working entrepreneurs deserve access to the full power of bitcoin.”
To prove the vision in action, Block helped power a Guinness World Record attempt for the most Lightning payments in a day, hosted live at the conference. The goal: prove that Lightning payments aren’t just functional—they’re scalable, fast, and real.
Block’s commitment isn’t new. In 2020, the company put bitcoin on its balance sheet. In 2021, it co-founded the Bitcoin Clean Energy Initiative to fight the “boiling oceans” narrative. In 2022, Cash App became one of the first major platforms on Lightning. In 2023, it launched on-chain payments with Square. And in 2024, it helped defeat Craig Wright in court, “standing up for Satoshi.”
“These aren’t just headlines—they’re a pattern,” Suter said. “We’ve made it more accessible, more secure. Now we’re focused on making it usable every day.”
Cash App already ranks among the top bitcoin on-ramps in the U.S., accounting for nearly 10% of on-chain block space at any time. In 2024, Lightning usage grew 7x. “Block runs one of the top Lightning nodes globally. And here’s what’s wild—it’s working,” he said.
Block is now taking 10% of all profits from Bitcoin and adding it back to its balance sheet, and over 1,700 merchants are automatically converting part of their daily sales to Bitcoin.
“If Bitcoin just becomes digital gold, we failed the mission,” Suter said. “Bitcoin payments validate Bitcoin. They make it real. Bitcoin is money.”

2025-05-29 16:15:13Life is full of ups and downs, uncertainties and challenges. But one of the most things life has is it ability to demand. It’s doesn’t care wether you’re sick, old, young, man or women. You must have something to offer .
I remember vividly what happened to me last year. It was time to resume school and my pops doesn’t have my tuition fee. So I decided to hustle for it by myself. I thought it’ll be easy, thinking I can get the money before the period of 1 month. I had my plans, but It seems like life has it own plans as well. I started doing some online businesses thinking it’s going to be alright. But then, all the things I engage myself in wasn’t going as planned. All my investments were gone, back to having a dry account and empty pockets. It was at that time I figured, life is playing with me. I nearly run mad during that period cause there was no one out there to help me go through this hardship. But then I remembered something that made me stopped over thinking. “You don’t know what tomorrow yield, you can die tonight and then everything will be useless” I keep this thought in my head. Why all the struggle for a life that you aren’t promised of tomorrow. We all sleep with the intentions of waking up the next day and continuing our lifestyle. But some of us don’t get to see tomorrow This thought made me think, I shouldn’t carry the weight of the world around my neck. It’s all useless if you die. There’s no point of all this struggle. This made me relieve the pressure I had on myself. And made me focus more on what am doing now instead of thinking of what’s going to happen in the future.
We should leave that aspect to GOD. A little advice to those young folks reading this. Don’t pressure yourself, what is meant for you will always be yours. And always have faith in GOD, he’s plans are better than yours. Life is hard and cruel, but when you decide to go with the thought that you alone can’t handle it all. That’s why GOD is there to handle our hidden battles for us.

GameStop CEO Ryan Cohen Announced Acquisition of Over $505 Million BitcoinAt the 2025 Bitcoin Conference in Las Vegas, in an interview with the CEO of Nakamoto David Bailey, the CEO of GameStop Ryan Cohen announced why the company bought over $505 million in Bitcoin.
JUST IN: GameStop $GME CEO explains why the company bought over $505 million #Bitcoin
“Bitcoin can be a hedge against global currency devaluation” pic.twitter.com/jNiId2fntA
— Bitcoin Magazine (@BitcoinMagazine) May 28, 2025
Ryan Cohen started by explaining some things about the GameStop business.
“When I took over, the company was a piece of crap and losing a lot of money and was under a lot of pressure moving from physical gains to digital downloads so you had to cut costs,” stated Cohen. “Very aggressively bringing physical discipline and we did. Retail is a tough business, but it was a big focus on getting cost under control.”
When Bailey asked Cohen how many Bitcoin GameStop owned, Ryan responded, “We currently own 4710 Bitcoin.”
Then Ryan mentioned why they are adding Bitcoin to their balance sheets.
“If the thesis is correct then Bitcoin and gold as well can be a hedge against global currency devaluation and systemic risk,” mentioned Ryan. “Bitcoin has certain unique advantages better than gold.”
He commented on the benefits of Bitcoin compared to gold.
“You can easily secure Bitcoin in a wallet whereas gold requires insurance and it’s very expensive and then there is the scarcity element of this as well,” commented Ryan. “There is a fixed supply of Bitcoin whereas with gold, the supply of gold is still uncertain.“
Ryan finished the announcement by saying, “GameStop is following GameStop Strategy. We are not following anyone else’s.”

2025-05-03 04:42:13Introduction
Me and Fishcake have been working on infrastructure for Noswhere and Nostr.build. Part of this involves processing a large amount of Nostr events for features such as search, analytics, and feeds.
I have been recently developing
nosdex
v3, a newer version of the Noswhere scraper that is designed for maximum performance and fault tolerance using FoundationDB (FDB).Fishcake has been working on a processing system for Nostr events to use with NB, based off of Cloudflare (CF) Pipelines, which is a relatively new beta product. This evening, we put it all to the test.
First preparations
We set up a new CF Pipelines endpoint, and I implemented a basic importer that took data from the
nosdex
database. This was quite slow, as it did HTTP requests synchronously, but worked as a good smoke test.Asynchronous indexing
I implemented a high-contention queue system designed for highly parallel indexing operations, built using FDB, that supports: - Fully customizable batch sizes - Per-index queues - Hundreds of parallel consumers - Automatic retry logic using lease expiration
When the scraper first gets an event, it will process it and eventually write it to the blob store and FDB. Each new event is appended to the event log.
On the indexing side, a
Queuer
will read the event log, and batch events (usually 2K-5K events) into one work job. This work job contains: - A range in the log to index - Which target this job is intended for - The size of the job and some other metadataEach job has an associated leasing state, which is used to handle retries and prioritization, and ensure no duplication of work.
Several
Worker
s monitor the index queue (up to 128) and wait for new jobs that are available to lease.Once a suitable job is found, the worker acquires a lease on the job and reads the relevant events from FDB and the blob store.
Depending on the indexing type, the job will be processed in one of a number of ways, and then marked as completed or returned for retries.
In this case, the event is also forwarded to CF Pipelines.
Trying it out
The first attempt did not go well. I found a bug in the high-contention indexer that led to frequent transaction conflicts. This was easily solved by correcting an incorrectly set parameter.
We also found there were other issues in the indexer, such as an insufficient amount of threads, and a suspicious decrease in the speed of the
Queuer
during processing of queued jobs.Along with fixing these issues, I also implemented other optimizations, such as deprioritizing
Worker
DB accesses, and increasing the batch size.To fix the degraded
Queuer
performance, I ran the backfill job by itself, and then started indexing after it had completed.Bottlenecks, bottlenecks everywhere
After implementing these fixes, there was an interesting problem: The DB couldn't go over 80K reads per second. I had encountered this limit during load testing for the scraper and other FDB benchmarks.
As I suspected, this was a client thread limitation, as one thread seemed to be using high amounts of CPU. To overcome this, I created a new client instance for each
Worker
.After investigating, I discovered that the Go FoundationDB client cached the database connection. This meant all attempts to create separate DB connections ended up being useless.
Using
OpenWithConnectionString
partially resolved this issue. (This also had benefits for service-discovery based connection configuration.)To be able to fully support multi-threading, I needed to enabled the FDB multi-client feature. Enabling it also allowed easier upgrades across DB versions, as FDB clients are incompatible across versions:
FDB_NETWORK_OPTION_EXTERNAL_CLIENT_LIBRARY="/lib/libfdb_c.so"
FDB_NETWORK_OPTION_CLIENT_THREADS_PER_VERSION="16"
Breaking the 100K/s reads barrier
After implementing support for the multi-threaded client, we were able to get over 100K reads per second.
You may notice after the restart (gap) the performance dropped. This was caused by several bugs: 1. When creating the CF Pipelines endpoint, we did not specify a region. The automatically selected region was far away from the server. 2. The amount of shards were not sufficient, so we increased them. 3. The client overloaded a few HTTP/2 connections with too many requests.
I implemented a feature to assign each
Worker
its own HTTP client, fixing the 3rd issue. We also moved the entire storage region to West Europe to be closer to the servers.After these changes, we were able to easily push over 200K reads/s, mostly limited by missing optimizations:
It's shards all the way down
While testing, we also noticed another issue: At certain times, a pipeline would get overloaded, stalling requests for seconds at a time. This prevented all forward progress on the
Worker
s.We solved this by having multiple pipelines: A primary pipeline meant to be for standard load, with moderate batching duration and less shards, and high-throughput pipelines with more shards.
Each
Worker
is assigned a pipeline on startup, and if one pipeline stalls, other workers can continue making progress and saturate the DB.The stress test
After making sure everything was ready for the import, we cleared all data, and started the import.
The entire import lasted 20 minutes between 01:44 UTC and 02:04 UTC, reaching a peak of: - 0.25M requests per second - 0.6M keys read per second - 140MB/s reads from DB - 2Gbps of network throughput
FoundationDB ran smoothly during this test, with: - Read times under 2ms - Zero conflicting transactions - No overloaded servers
CF Pipelines held up well, delivering batches to R2 without any issues, while reaching its maximum possible throughput.
Finishing notes
Me and Fishcake have been building infrastructure around scaling Nostr, from media, to relays, to content indexing. We consistently work on improving scalability, resiliency and stability, even outside these posts.
Many things, including what you see here, are already a part of Nostr.build, Noswhere and NFDB, and many other changes are being implemented every day.
If you like what you are seeing, and want to integrate it, get in touch. :)
If you want to support our work, you can zap this post, or register for nostr.land and nostr.build today.

2025-05-29 17:39:18People say AI can’t create anything truly original. They’re right, because creativity doesn’t come from machines. Machines have no senses, no instincts, no ability to act in the real world. They’ve never tasted danger, felt grief, or made a sacrifice. Creativity belongs to those who have lived life. It comes to men and women who know what they’re doing through experience.
AI is not a writer or an artist. It is a tool. A calculator that uses words instead of numbers to guess what you want to hear. It has no soul, no experience, no skin in the game.
If you want to create something real, you must be the mind and heart behind the words. You must put your own inner fire into it. The AI is just the forge that lets you work the letters into place.
What AI Can't Do, And What You Must
This is how I write with AI. This is my process.
Step One: Define the Mission
First, I decide:
-
What I’m writing (length, format, scope, tone)
-
What I want to say (thesis)
-
How I’ll prove it (supporting points)
Step Two: Attack Your Idea Before You Defend It
Then I open up a conversation with the AI. Not to write but to challenge my ideas.
I ask it to generate a falsification prompt, a structured attack on my idea. But this requires precision. AI is not designed to challenge you. It’s trained to agree with you, to reflect consensus. So you have to hack it.
You must write a prompt that forces it to become adversarial, not based on popular opinion, but grounded in first principles. And even then, you must define which first principles matter. Clarity here sets the boundaries of the entire piece. This is the most important prompt in the process.
Then I run that prompt in a second thread. I hunt for weak points. I keep running tests until my idea holds. Only then do I continue.
Step Three: Map the Consequences
Next, I ask for second- and third-order consequences. What happens if this idea is applied in real life? What breaks? What works?
But even here, I don’t take its answers at face value. I ask it to falsify its own guesstimations, because that’s what they are, a mixture of guess and estimation, with no grounding in lived experience.
I push it to argue against itself, to challenge the implications it just offered. And I only accept what survives both prediction and pressure.
Now the shape is clear.
Step Four: Begin the First Draft
Only then do I tell the AI to begin drafting.
I give it a long, detailed prompt. Part of it is recycled between posts: my grammar rules, my format, my tone, my values. Some of it I keep saved in a PDF and drop in. The rest is tailored to the post at hand, instructions I generate during the previous steps, shaped by my interactions with the AI. The goal isn’t perfection. The goal is a useful skeleton I can flesh out. It gives me something usable but bland that covers the main points.
Step Five: Speak the Edits
Then I speak.
I dictate edits. I tell it what to keep, what to rewrite and how, what it missed. I move pieces around until the best arguments sit in the best possible order. When I’m finished, the post is 90% my own words. The AI added glue, structure, flow, formating. Nothing more.
Step Six: Quality Control
Now I run my quality checks. I ask a stock set of questions:
-
Does the summary of my idea still make sense?
-
Is the grammar consistent and clean?
-
Am I repeating myself?
-
Are the tenses correct?
-
Does my argument still hold up?
This is especially important for long posts. The goal is polish. Polish means clarity, rhythm, logic, and precision. Nothing missed. Nothing wasted. No extra words.
I also lean on insights from Joshua Lisec’s (@JoshuaLisec) The Best Way to Write It course. It taught me how to spot my typical writing flaws, and now I hold myself to that higher standard. The longer the document, the more important this phase becomes. Quality control doesn’t just clean up the surface, it keeps the message on brand, sharp, structured, and true.
This Is Amplification, Not Automation
This is not automation. It is amplification.
Automation replaces intention. Amplification serves it.
Automation assumes the machine should think for you. Amplification sharpens what you already know.
The AI didn’t create the message. It didn’t understand the truth of it. It didn’t live the stories that forged it. What it did, at its best, was help me say it faster, clearer, sharper.
Amplification means I can reach more people with less friction. It means I can test ideas at scale, refine arguments quickly, and stay in the rhythm of writing without stopping to reformat every sentence.
It’s not slop. It’s not a shortcut. It’s strategic leverage. But only if you already have something worth saying.
Most people don’t. Even many prolific writers don’t. They recycle ideas from one audience and feed them to another, a younger, more naive crowd that’s never heard them before. They mistake that for creativity.
I’ll be open with you: I rarely invent new ideas. I don’t need to. I write about ancient truths, time-tested strategies, the hard-won lessons of life.
What I do is connect what’s always worked with what’s possible now. I explain. I teach. And in person, I read people. I see what’s missing in them, and I help them see it too. Then together we build the missing pieces.
That’s not something you can fake. It’s not something AI can simulate. You have to live in order to have something worth saying. So the AI gives most people nothing. But if you’ve lived, if you’ve suffered and built and learned, then it can give you speed, clarity, and consistency in communicating that to others. But only if you lead it.
Why Most People Fail with AI
Most people fail with AI because they expect it to do the thinking. It can’t. It can only organize what you tell it.
If your results are vague, weak, or generic, it’s because:
-
You aren’t clear on what you want
-
You don’t know how to communicate boundaries
The problem is not the machine. The problem is your executive function is lacking.
Nonfiction Writing Was Always a Team Effort
Many nonfiction writers have always worked this way: Surrounded by assistants. Speaking out loud. Sorting ideas in real time. Having the best material refined and tested by teammates.
This isn’t about fiction, which is often best created in solitude, slowly, by a single mind over many years. Fiction doesn’t have to be real. It has to feel real. But nonfiction must follow truth. It must be grounded in reality, tested, and safe to apply. People get hurt if it isn’t.
There’s also a difference between writing because it’s your job and writing because you have something important to share. I don’t write for a living. I write because I know things that can help people, and that knowledge demands to be passed on.
If writing is your job, of course you’ll spend much more time on it. You’ll hire editors, assistants, researchers. Or AI can help with that, it’s low cost leverage. But if writing is your service, your legacy, your offering to the world, then you must be efficient. You must learn how to dictate, delegate, and get the truth out. Faster and better.
That’s what I do. And AI is the best assistant I’ve ever had for the money.
Even Trump writes this way. He speaks. His team organizes, sharpens, packages, gives him feedback.
Now you can do the same. For only $20 a month.
But only if you lead. Only if you know who you are, what you want to say, and how to direct a team. Because managing an AI is little different than managing people. You must have a solidly established ego. You must know how to set boundaries and hold them. You must be an expert communicator. The same executive skills that make you a capable leader in life are the ones that let you get real value from AI. Without them, it will run you.
Because this is your team. And you’re the head of it.
Final Truth: Lead or Be Led
Different people are getting vastly different results from AI. Some are producing brilliant work. Others are spinning in circles. When that happens, the problem isn’t the tool. It’s the user.
Any time a group uses the same tool and outcomes vary wildly, the difference is in the people, not the technology.
AI is perhaps the most complex tool humanity has ever built. It’s going to change the world, just like the printing press, the internet, and smartphones did. Whether that change is good or catastrophic depends on the quality of the people using it.
People with weak egos, poor boundaries, and low agency will be swept away. They’ll lose track of themselves. They’ll be absorbed into someone else’s machine. Not because they’re stupid. But because they’ve never trained their minds to resist.
And they will blame the tool. They’ll say, "This time it’s different." They’ll panic, moralize, or make excuses. But it’s the same pattern we’ve seen with every new influence system: TV, radio, social media.
The real issue is agency. If you have it, you use the tool. If you don’t, the tool uses you.
You can’t stop AI. But you can rise above its dangers. You can train your internal architecture to remain sovereign, no matter how powerful the machine gets.
If you want to build that kind of fortitude, the kind that makes you immune to being used, I can help you. That’s what I do.
Lead your thoughts. Lead your message. Use your tools like a man who knows what he’s building.

2025-05-29 15:52:45Bulgária: Először töltenek be Westinghouse-üzemanyagot a Kozloduy-5-be
Először töltöttek be Westinghouse által gyártott nukleáris üzemanyag-kazettákat Bulgária Kozloduy-5 VVER-1000 reaktorába 2025. május 29-én. Ez jelentős lépés Szófia azon törekvésében, hogy csökkentse orosz nukleáris üzemanyag-függőségét, és diverzifikálja energiaforrásait. A lépés része annak a szélesebb stratégiának, amelynek célja az energiaellátás biztonságának növelése és a nyugati partnerekkel való szorosabb együttműködés[NucNet].
Fehér Ház: Nukleáris Telepítési Csúcstalálkozó az USA-ban
A mai napon a Fehér Ház Nukleáris Telepítési Csúcstalálkozót tartott, amelyen kiemelték a köz- és magánszféra eredményeit. Fő témák voltak az orosz urántól való amerikai függőség csökkentése, a nukleáris üzemanyag-ellátási lánc bővítése, valamint a globális nukleáris kapacitás 2050-ig történő megháromszorozásának támogatása. A csúcson szó esett a nagy nukleáris projektek kockázatainak csökkentéséről, új reaktortervezetekről és a meglévő atomerőművek élettartamának meghosszabbításáról is. Az amerikai kormány hangsúlyozta, hogy továbbra is támogatja a fejlett nukleáris demonstrációs projekteket, a munkaerő-fejlesztést, valamint a legújabb törvényhozási lépéseket, például az orosz uránimport tilalmáról szóló törvényt[World Nuclear News].
Törékeny áramellátás a zaporizzsjai atomerőműben, Ukrajna
Az IAEA jelentése szerint az ukrajnai Zaporizzsjai Atomerőmű továbbra is rendkívül sebezhető helyzetben van, mivel jelenleg csak egyetlen külső áramvezetékre támaszkodik a biztonsági rendszerek működtetéséhez. Az utolsó tartalék vezeték három hete le van választva, ami aggodalomra ad okot a hűtő- és biztonsági rendszerek stabilitását illetően. Bár a létesítmény három éve nem termel áramot, folyamatos elektromos ellátásra van szükség a kiégett fűtőelemek hűtéséhez. Az IAEA továbbra is szorosan figyelemmel kíséri a helyzetet, és kiemeli a régióban zajló katonai tevékenységet[IAEA].
USA: SMR-fejlesztések és költségvetési megszorítások
A Tennessee Valley Authority benyújtotta az építési engedélykérelmet egy GE Vernova Hitachi BWRX-300 típusú kis moduláris reaktor (SMR) telepítésére a Clinch River helyszínen, ami jelentős előrelépés az amerikai SMR-programban. Eközben az amerikai kormány 2026-os költségvetési tervezete jelentős csökkentéseket irányoz elő az Energiaügyi Minisztérium nukleáris finanszírozásában, különösen a nem elsődleges kutatási területeken. A fókusz az innovatív reaktorkoncepciókra, fejlett üzemanyagokra és a kulcsfontosságú nemzeti laboratóriumi képességek fenntartására helyeződik[World Nuclear News][World Nuclear News].
Savannah River Site: Előrelépés a plutónium-magházak gyártásában
Az amerikai Energiaügyi Minisztérium Savannah River telephelyén megkezdődött a kesztyűs dobozok gyártása a plutónium magházak előállításához. Ezek a kesztyűs dobozok kulcsfontosságúak a Savannah River Plutonium Processing Facility számára, amely a Nemzeti Nukleáris Biztonsági Igazgatóság célkitűzéseit támogatja, hogy a projektet a 2030-as évek elejéig befejezzék.

Nemzetközi trendek: ellátási lánc és új reaktorprojektek
A nukleáris ellátási lánc a globális növekedésre készül, ahogy azt a World Nuclear Association legutóbbi konferenciáján is hangsúlyozták. Kiemelt nemzetközi fejlemények:

2025-05-29 15:21:33What’s Happening in Japan? Japan has the highest debt-to-GDP ratio in the developed world — over 260%. For decades, it got away with this by keeping interest rates near zero and having the Bank of Japan (BoJ) purchase most of its government bonds. This was known as Yield Curve Control — a desperate attempt to keep borrowing costs low.
But now, global bond markets are revolting.
🔺 Japanese 30-year yields have exploded past 3.18%
🔺 The worst bond auction since 1987 just occurred
🔺 Demand for JGBs (Japanese Government Bonds) is collapsing
When demand for bonds falls, prices drop and yields rise. This signals fear. Big fear.
As Taylor Kenney noted in a widely shared thread:
“This isn’t just a Japan problem — Japan is the largest foreign holder of U.S. debt.” The Contagion Risk: U.S. Debt and Global Collapse
Here’s where this gets truly global.
In 2025 alone, $9.2 trillion of U.S. debt will mature — 70% of it between January and June. That debt must be refinanced, and as interest rates remain elevated, the cost of servicing this debt balloons, potentially straining the U.S. government’s finances.
If yields rise further, it only worsens the cycle:
-
Yields rise
-
Interest costs balloon
-
Governments print more to cover deficits
-
Currencies debase
-
Confidence dies
-
Collapse follows
Japan may just be the canary in the coal mine. Gold Is Surging. Bitcoin Is Outpacing It.
Smart money is already moving.
Bitcoin is closing in on its all-time high — and closely tracking the M2 Global Liquidity Index, historically lagging it by 60–90 days.
Gold has also had a stellar run in 2025, signalling institutional flight to hard assets.
People are scared. And they should be.
The global financial system is built on an unsustainable foundation of debt, inflation, and artificial suppression of interest rates. That system is now cracking in Japan — but it won’t stop there. ₿ Bitcoin: The Exit Plan
Bitcoin doesn’t rely on a central bank.
It doesn’t need to be refinanced.
It doesn’t have a yield curve to control.
It’s decentralised, scarce, and incorruptible.
While fiat currencies spiral under the weight of debt and monetary debasement, Bitcoin offers an escape — a monetary protocol with a fixed supply and no political manipulation.
It’s not just an investment.
It’s an exit strategy from the madness. Final Thoughts
-
Japan is flashing red.
-
The U.S. is next in line.
-
The debt system is spiralling — fast.
Gold is insurance.
Bitcoin is the lifeboat.

どうも、「NostrはLNがWeb統合されマネーのインターネットプロトコルとしてのビットコインが本気出す具体行動のショーケースと見做せばOK」です、こんばんは。
またまた実験的な試みがNostrで行われているのでレポートします。本シリーズはライブ感を重視しており、例によって(?)プルリクエストなどはレビュー段階なのでご承知おきください。
今回の主役はあくまでLightningNetworkの新提案(ただし以前からあるLSATからのリブランディング)となるLightning HTTP 402 Protocol(略称: L402)です。そのショーケースの一つとしてNostrが活用されているというものになります。
Lightning HTTP 402 Protocol(略称: L402)とは何か
bLIPに今月挙がったプロポーザル内容です。
https://github.com/lightning/blips/pull/26
L402について私はまだ完全に理解した段階ではあるのですがなんとか一言で説明しようとすると「Authトークンのように"Paid"トークンをHTTPヘッダーにアタッチして有料リソースへのHTTPリクエストの受け入れ判断を行えるようにする」ものだと解釈しました。
Authenticationでは、HTTPヘッダーにAuthトークンを添付し、その検証が通ればHTTPリクエストを許可し、通らなければ
401 Unauthorized
コードをエラーとして返すように定められています。https://developer.mozilla.org/ja/docs/Web/HTTP/Status/401
L402では、同じように、HTTPヘッダーに支払い済みかどうかを示す"Paid"トークンを添付し、その検証が通ればHTTPリクエストを許可し、通らなければ
402 Payment Required
コードをエラーとして返すようにしています。なお、"Paid"トークンという用語は私の造語となります。便宜上本記事では使わせていただきますが、実際はAuthも入ってくるのが必至ですし、プルリクエストでも用語をどう定めるかは議論になっていることをご承知おきください。("API key", "credentials", "token", らが登場しています)
この402ステータスコードは従来から定義されていましたが、MDNのドキュメントでも記載されているように「実験的」なものでした。つまり、器は用意されているがこれまで活用されてこなかったものとなり、本プロトコルの物語性を体現しているものとなります。
https://developer.mozilla.org/ja/docs/Web/HTTP/Status/402
幻であったHTTPステータスコード402 Payment Requiredを実装する
この物語性は、上述のbLIPのスペックにも詳述されていますが、以下のスライドが簡潔です。
402 Payment Required
は予約されていましたが、けっきょくのところWorldWideWebはペイメントプロトコルを実装しなかったので、Bitcoinの登場まで待つことになった、というのが要旨になります。このWorldWideWebにおける決済機能実装に関する歴史話はクリプト界隈でもたびたび話題に上がりますが、そこを繋いでくる文脈にこれこそマネーのインターネットプロトコルだなと痺れました。https://x.com/AlyseKilleen/status/1671342634307297282
この"Paid"トークンによって実現できることとして、第一にAIエージェントがBitcoin/LNを自律的に利用できるようになるM2M(MachineToMachine)的な話が挙げられていますが、ユースケースは想像力がいろいろ要るところです。実際のところは「有料リソースへの認可」を可能にすることが主になると理解しました。本連載では、繰り返しNostrクライアントにLNプロトコルを直接搭載せずにLightningNetworkを利用可能にする組み込み方法を見てきましたが、本件もインボイス文字列 & preimage程度の露出になりアプリケーション側でノードやウォレットの実装が要らないので、その文脈で位置付ける解釈もできるかと思います。
Snortでのサンプル実装
LN組み込み業界のリーディングプロダクトであるSnortのサンプル実装では、L402を有料コンテンツの購読に活用しています。具体的には画像や動画を投稿するときに有料のロックをかける、いわゆるペイウォールの一種となります。もともとアップローダもSnortが自前で用意しているので、そこにL402を組み込んでみたということのようです。
体験方法の詳細はこちらにあります。 https://njump.me/nevent1qqswr2pshcpawk9ny5q5kcgmhak24d92qzdy98jm8xcxlgxstruecccpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhszrnhwden5te0dehhxtnvdakz78pvlzg
上記を試してみた結果が以下になります。まず、ペイウォールでロックした画像がNostrに投稿されている状態です。まったくビューワーが実装されておらず、ただのNotFound状態になっていますが、支払い前なのでロックされているということです。
次にこのHTTP通信の内容です。
通信自体はエラーになっているわけですが、ステータスコードが402で、レスポンスヘッダーのWWW-AuthenticateにInvoice文字列が返ってきています。つまり、このインボイスを支払えば"Paid"トークンが付与されて、その"Paid"トークンがあれば最初の画像がアンロックされることとなります。残念ながら現在は日本で利用不可のStrikeAppでしか払込みができないためここまでとなりますが、本懐である
402 Payment Required
とインボイス文字列は確認できました。今確認できることは以上ですが、AmethystやDamusなどの他のNostrクライアントが実装するにあたり、インラインメディアを巡ってL402の仕様をアップデートする必要性や同じくHTTPヘッダーへのAuthトークンとなるNIP-98と組み合わせるなどの議論が行われている最中です。
LinghtningNetworkであるからこそのL402の実現
"Paid"トークンを実現するためにはLightningNetworkのファイナリティが重要な要素となっています。逆に言うと、reorgによるひっくり返しがあり得るBitcoinではできなくもないけど不便なわけです。LightningNetworkなら、当事者である二者間で支払いが確認されたら「同期的」にその証であるハッシュ値を用いて"Paid"トークンを作成することができます。しかもハッシュ値を提出するだけで台帳などで過去の履歴を確認する必要がありません。加えて言うと、受金者側が複数のノードを建てていて支払いを受け取るノードがどれか一つになる状況でも、つまり、スケーリングされている状況でも、"Paid"トークンそのものはどのノードかを気にすることなくステートレスで利用できるとのことです。(ここは単にreverse proxyとしてAuthサーバががんばっているだけと解釈することもできますがずいぶんこの機能にも力点を置いていて大規模なユースケースが重要になっているのだなという印象を抱きました)
Macaroonの本領発揮か?それとも詳細定義しすぎか?
HTTP通信ではWWW-Authenticateの実値にmacaroonの記述が確認できます。また現在のL402スペックでも"Paid"トークンにはmacaroonの利用が前提になっています。
このmacaroonとは(たぶん)googleで研究開発され、LNDノードソフトウェアで活用されているCookieを超えるという触れ込みのデータストアになります。しかし、あまり普及しなかった技術でもあり、個人の感想ですがなんとも微妙なものになっています。
https://research.google/pubs/macaroons-cookies-with-contextual-caveats-for-decentralized-authorization-in-the-cloud/
macaroonの強みは、Cookieを超えるという触れ込みのようにブラウザが無くてもプロセス間通信でデータ共有できる点に加えて、HMACチェーンで動的に認証認可を更新し続けられるところが挙げられます。しかし、そのようなユースケースがあまり無く、静的な認可となるOAuthやJWTで十分となっているのが現状かと思います。
L402では、macaroonの動的な更新が可能である点を活かして、"Paid"トークンを更新するケースが挙げられています。わかりやすいのは上記のスライド資料でも挙げられている"Dynamic Pricing"でしょうか。プロポーザルではloop©️LightningLabsにおいて月間の最大取引量を認可する"Paid"トークンを発行した上でその条件を動向に応じて動的に変更できる例が解説されています。とはいえ、そんなことしなくても再発行すればええやんけという話もなくもないですし、プルリクエストでも仕様レベルでmacaroonを指定するのは「具体」が過ぎるのではないか、もっと「抽象」し単なる"Opaque Token"程度の粒度にして他の実装も許容するべきではないか、という然るべきツッコミが入っています。
個人的にはそのツッコミが妥当と思いつつも、なんだかんだ初めてmacaroonの良さを実感できて感心した次第です。

どうも、「NostrはLNがWeb統合されマネーのインターネットプロトコルとしてのビットコインが本気出す具体行動のショーケースと見做せばOK」です、こんにちは。
前回まで投げ銭や有料購読の組み込み方法を見てきました。
zapsという投げ銭機能が各種クライアントに一通り実装されて活用が進んでいることで、統合は次の段階へ移り始めています。「作戦名: ウォレットをNostrクライアントに組み込め」です。今回はそちらをまとめます。
投げ銭する毎にいちいちウォレットを開いてまた元のNostrクライアントに手動で戻らないといけない is PAIN
LNとNostrはインボイス文字列で繋がっているだけの疎結合ですが、投稿に投げ銭するためには何かのLNウォレットを開いて支払いをして、また元のNostrクライアントに戻る操作をユーザーが手作業でする必要があります。お試しで一回やる程度では気になりませんが普段使いしているとこれはけっこうな煩わしさを感じるUXです。特にスマホでは大変にだるい状況になります。連打できない!
2月の実装以来、zapsは順調に定着して日々投げられています。
https://stats.nostr.band/#daily_zaps
なので、NostrクライアントにLNウォレットの接続を組み込み、支払いのために他のアプリに遷移せずにNostクライアント単独で完結できるようなアップデートが始まっています。
Webクライアント
NostrのLN組み込み業界のリーディングプレイヤーであるSnortでの例です。以下のようにヘッダーのウォレットアイコンをクリックすると連携ウォレットの選択ができます。
もともとNostrに限らずウェブアプリケーションとの連携をするために、WebLNという規格があります。簡単に言うと、ブラウザのグローバル領域を介して、LNウォレットの拡張機能と、タブで開いているウェブアプリが、お互いに連携するためのインターフェースを定めているものです。これに対応していると、LNによる支払いをウェブアプリが拡張機能に依頼できるようになります。さらにオプションで「確認無し」をオンにすると、拡張機能画面がポップアップせずにバックグラウンドで実行できるようになり、ノールック投げ銭ができるようになります。
似たようなものにNostrではNIP-07があります。NIP-07はNostrの秘密鍵を拡張機能に退避して、Nostrクライアントは秘密鍵を知らない状態で署名や複合を拡張機能に移譲できるようにしているものです。
Albyの拡張機能ではWebLNとNIP-07のどちらにも対応しています。
実はSnortはzapsが来る前からWebLNには対応していたのですが、さらに一歩進み、拡張機能ウォレットだけでなく、LNノードや拡張機能以外のLNウォレットと連携設定できるようになってきています。
umbrelなどでノードを立てている人ならLND with LNCでノードと直接繋げます。またLNDHubに対応したウォレットなどのアプリケーションとも繋げます。これらの接続は、WebLNにラップされて拡張機能ウォレットとインターフェースを揃えられた上で、Snort上でのインボイスの支払いに活用されます。
なお、LNCのpairingPhrase/passwordやLNDHubの接続情報などのクレデンシャルは、ブラウザのローカルストレージに保存されています。Nostrのリレーサーバなどには送られませんので、端末ごとに設定が必要です。
スマホアプリ
今回のメインです。なお、例によって(?)スペックは絶賛議論中でまだフィックスしていない中で記事を書いています。ディテールは変わるかもしれないので悪しからずです。
スマホアプリで上記のことをやるためには、後半のLNCやLNDHubはすでにzeusなどがやっているようにできますが、あくまでネイティブウォレットのラッパーです。Nostrでは限られた用途になるので1-click支払いのようなものを行うためにはそこから各スマホアプリが作り込む必要があります。まあこれはこれでやればいいという話でもあるのですが、LNノードやLNウォレットのアプリケーション側へのインターフェースの共通仕様は定められていないので、LNDとcore-lightningとeclairではすべて実装方法が違いますし、ウォレットもバラバラなので大変です。
そこで、多種多様なノードやウォレットの接続を取りまとめ一般アプリケーションへ統一したインターフェースを媒介するLN Adapter業界のリーディングカンパニーであるAlbyが動きました。AndroidアプリのAmethystで試験公開されていますが、スマホアプリでも上記のSnortのような連携が可能になるようなSDKが開発されました。
リリース記事 https://blog.getalby.com/native-zapping-in-amethyst/
"Unstoppable zapping for users"なんて段落見出しが付けられているように、スマホで別のアプリに切り替えてまた元に戻らなくても良いようにして、Nostr上でマイクロペイメントを滑らかにする、つまり、連打できることを繰り返し強調しています。
具体的にやっていることを見ていきます。以下の画像群はリリース記事の動画から抜粋しています。各投稿のzapsボタン⚡️をタップしたときの画面です。
上の赤枠が従来の投げ銭の詳細を決める場所で、下の赤枠の「Wallet Connect Service」が新たに追加されたAlby提供のSDKを用いたコネクト設定画面です。基本的にはOAuth2.0ベースのAlbyのAPIを活用していて、右上のAlbyアイコンをタップすると以下のようなOAuthの認可画面に飛びます。(ただし後述するように通常のOAuthとは一部異なります。)
画面デザインは違いますが、まあ他のアプリでよく目にするTwitter連携やGoogleアカウント連携とやっていることは同じです。
このOAuthベースのAPIはNostr専用のエンドポイントが建てられています。Nostr以外のECショップやマーケットプレイスなどへのAlbyのOAuthは汎用のエンドポイントが用意されています。よって通常のAlbyの設定とは別にセッション詳細を以下のサイトで作成する必要があります。
https://nwc.getalby.com/ (サブドメインのnwcはNostr Wallet Connectの略)
なぜNostrだけは特別なのかというところが完全には理解しきれていないですが、以下のところまで確認できています。一番にあるのは、Nostrクライアントにウォレットを組み込まずに、かつ、ノードやウォレットへの接続をNostrリレーサーバ以外は挟まずに"decentralized"にしたいというところだと理解しています。
- 上記のnwcのURLはalbyのカストディアルウォレットusername@getalby.comをNostrに繋ぐもの(たぶん)
- umbrelのLNノードを繋ぐためにはやはり専用のアプリがumbrelストアに上がっている。https://github.com/getAlby/umbrel-community-app-store
- 要するにOAuthの1stPartyの役割をウォレットやノードごとにそれぞれ建てる。
- OAuthのシークレットはクライアントに保存するので設定は各クライアント毎に必要。しかし使い回しすることは可能っぽい。通常のOAuthと異なり、1stParty側で3rdPartyのドメインはトラストしていないようなので。
- Nostrクライアントにウォレットを組み込まずに、さらにウォレットやノードへの接続をNostrリレーサーバ以外には挟まなくて良いようにするために、「NIP-47 Nostr Wallet Connect」というプロポーザルが起こされていて、絶賛議論中である。https://github.com/nostr-protocol/nips/pull/406
- このWallet Connect専用のアドホックなリレーサーバが建てられる。その情報が上記画像の赤枠の「Wallet Connect Service」の下半分のpub keyやらrelayURL。どうもNostrクライアントはNIP-47イベントについてはこのリレーサーバにしか送らないようにするらしい。(なんかNostrの基本設計を揺るがすユースケースの気がする...)
- Wallet Connect専用のNostrイベントでは、ペイメント情報をNostrアカウントと切り離すために、Nostrの秘密鍵とは別の秘密鍵が利用できるようにしている。
Imagin the Future
今回取り上げたNostrクライアントにウォレット接続を組み込む話を、Webのペイメントの歴史で類推してみましょう。
Snortでやっていることは、各サイトごとにクレジットカードを打ち込み各サイトがその情報を保持していたようなWeb1.0の時代に近いです。そうなるとクレジットカードの情報は各サービスごとに漏洩リスクなどがあり、Web1.0の時代はECが普及する壁の一つになっていました。(今でもAmazonなどの大手はそうですが)
Webではその後にPayPalをはじめとして、銀行口座やクレジットカードを各サイトから切り出して一括管理し、各ウェブサイトに支払いだけを連携するサービスが出てきて一般化しています。日本ではケータイのキャリア決済が利用者の心理的障壁を取り除きEC普及の後押しになりました。
後半のNostr Wallet ConnectはそれをNostrの中でやろうとしている試みになります。クレジットカードからLNに変える理由はビットコインの話になるので詳細は割愛しますが、現実世界の金(ゴールド)に類した価値保存や交換ができるインターネットマネーだからです。
とはいえ、Nostrの中だけならまだしも、これをNostr外のサービスで利用するためには、他のECショップやブログやSaaSがNostrを喋れる必要があります。そんな未来が来るわけないだろと思うかもしれませんが、言ってみればStripeはまさにそのようなサービスとなっていて、サイト内にクレジット決済のモジュールを組み込むための主流となっています。
果たして、Nostrを、他のECショップやブログやSaaSが喋るようになるのか!?
以上、「NostrはLNがWeb統合されマネーのインターネットプロトコルとしてのビットコインが本気出す具体行動のショーケースと見做せばOK」がお送りしました。

2025-05-29 15:19:56The Weimar Hyperinflation Nightmare
It’s 1921. Germany’s reeling from World War I, crushed by reparations and a wrecked economy. The government’s solution? Print money. Lots of it. The German mark starts tanking. By 1923, it’s a joke—4.2 trillion marks to one U.S. dollar. A loaf of bread costs wheelbarrows of cash. Savings? Wiped out. Middle-class families? Pauperized. Chaos.
Enter Hugo Stinnes, a coal and steel magnate with a sharp mind and sharper instincts. He sees the game: when a currency’s dying, debt is your friend. Why? Because the real value of your loans shrinks as inflation skyrockets. Borrow 1 million marks today, buy a factory, and by next year, that million’s worth a few pennies. Pay it back, keep the factory, repeat.
Stinnes’ Master Play
Stinnes goes all in. He borrows billions of marks, snapping up hard assets—steel mills, shipping lines, factories, real estate. Tangible stuff that holds value while paper marks turn to confetti. By 1923, his empire is a beast: over 1,500 companies, from coal mines to newspapers. Estimates say he controlled 15-20% of Germany’s industry, maybe more. A third of the economy? Probably an exaggeration, but the guy was a titan.
He wasn’t just lucky. Stinnes played 4D chess. He diversified his holdings to weather the storm, employed tens of thousands (keeping unrest at bay), and even argued his empire stabilized the economy. Critics, like British diplomat Lord D’Abernon, weren’t buying it—they called him a profiteer who thrived while others starved. Truth? Probably somewhere in the middle.
The Fall
Hyperinflation couldn’t last forever. In November 1923, Germany introduced the Rentenmark, a new currency backed by land and assets. The mark’s freefall stopped. Stinnes’ debt-fueled strategy hit a wall—stable currencies make loans harder to game. His health was failing too. He died in 1924, and his conglomerate started unraveling, with parts sold off or restructured. The Inflation King’s reign was over.
Why This Matters Today: Enter Bitcoin
Stinnes’ story isn’t just a history lesson—it’s a warning. Hyperinflation destroys trust in fiat money. When governments print cash to cover debts, savers get crushed, and the clever (or ruthless) like Stinnes exploit the chaos. Sound familiar? Look at today: global debt’s at $315 trillion, central banks are juggling interest rates, and inflation’s eating purchasing power. Argentina’s peso lost 50% of its value in 2024 alone. Venezuela’s bolívar? Toast.
This is where Bitcoin comes in. Born in 2009 after the financial crisis, Bitcoin is a hedge against fiat’s flaws. Unlike marks or dollars, it’s decentralised—no government can print more to pay its bills. Its supply is capped at 21 million coins, making it “digital gold.” When fiat currencies wobble, Bitcoin’s value often spikes—check its 2021 and 2024 bull runs during inflation fears.
Stinnes gamed a broken system by betting on hard assets. Today, Bitcoiners are doing the same, but instead of factories, they’re stacking sats. Why? Because in a world where fiat can be printed to oblivion, a deflationary asset like Bitcoin holds appeal. It’s not perfect—volatility’s a beast, and governments hate what they can’t control—but it’s a response to the same problem Stinnes faced: untrustworthy money.
The Lesson
Stinnes saw the Weimar collapse coming and turned it into wealth. Most didn’t. Today, you don’t need to be a tycoon to protect yourself, but you do need to understand the game. Fiat’s not collapsing tomorrow, but cracks are showing. Bitcoin’s one tool—maybe not the only one—to hedge against that risk. Study history, question the system, and don’t get caught holding the bag.

2025-05-29 15:17:06Bitcoin’s Path to Global Dominance: Store of Value, Medium of Exchange, and the Road to a Bitcoin Standard
Bitcoin has ignited a financial revolution, captivating everyone from tech enthusiasts to institutional investors. Yet, amidst its meteoric rise, a tantalising question emerges: Could Bitcoin become the world’s reserve currency, relegating fiat currencies to the history books? This vision—a global Bitcoin standard—stirs intense debate within the community. Some champion Bitcoin as a Store of Value (SOV), a digital equivalent to gold, while others insist its future lies in becoming a Medium of Exchange (MOE), used for everyday transactions. With conflicting perspectives and community members at varying points in their Bitcoin journey, it’s time to unpack these ideas and chart a unified course.
This article delves into the interplay between Bitcoin’s SOV and MOE roles, examines the hurdles to widespread adoption, and proposes a roadmap for Bitcoin to claim global reserve status. My goal is to ignite a vibrant discussion, bridge divides, and encourage the Bitcoin community to rally around a shared vision for the future.
The Building Blocks: What Are SOV and MOE?
To kick things off, let’s define the two pillars of this debate:
• Store of Value (SOV): An asset that holds or grows its worth over time, offering a dependable way to preserve wealth. Think gold, a classic example cherished for millennia.
• Medium of Exchange (MOE): A tool for transactions, enabling the seamless exchange of goods and services. Today, fiat currencies like the pound or dollar reign supreme in this domain.
Bitcoin’s allure stems from its unique traits: a capped supply of 21 million coins, a decentralised network, and immunity to censorship. These qualities position it as a contender to replace both gold and fiat money—but the journey is complex, and the community’s views are far from aligned.
Where We Stand: Bitcoin as Digital Gold
Bitcoin’s ascent has been propelled by its prowess as a Store of Value. Early adopters, savvy investors, and even big institutions have embraced it as a shield against inflation, economic turmoil, and the erosion of fiat value. Its scarcity—hardwired into its code—has cemented the “digital gold” narrative, drawing in those seeking a safe haven in uncertain times.
But here’s the rub: while Bitcoin shines as an SOV, it’s rarely used as an MOE. Its price swings, technical limitations, and patchy acceptance by merchants make it a tough sell for buying a pint or a loaf of bread. Many in the community—think of figures like Michael Saylor—preach the gospel of “hodling,” urging followers to stash Bitcoin away and watch its value soar. This strategy has paid off handsomely for some, but it begs a bigger question: Can Bitcoin rule the world if it remains a speculative treasure rather than a working currency?
The Adoption Puzzle: Bridging SOV and MOE
For Bitcoin to leap from a niche asset to the global reserve currency, it must become a widely accepted Medium of Exchange. This evolution matters for several reasons:
• Real-World Use Fuels Demand: When Bitcoin powers transactions, its value ties to tangible activity, not just market hype.
• Network Strength: More users mean a tougher, more valuable network—a classic network effect.
• Price Stability: Broader adoption could smooth out Bitcoin’s wild price rides, making it more practical for daily use.
Yet, hurdles abound. Bitcoin’s volatility is a dealbreaker for many—who’d spend it on a takeaway if it might double in value overnight? Then there’s the issue of “whales” or “max hodlers,” those holding vast swathes of Bitcoin. If too much of the supply sits idle, it starves the liquidity needed for an MOE to thrive.
The Hodler Debate: To Spend or Not to Spend?
A spirited clash within the community revolves around these large holders. Should they—like Saylor or early adopters—dip into their stacks to kickstart adoption? Hodling bolsters Bitcoin’s scarcity and SOV credentials, no doubt. But if the bulk of Bitcoin stays locked up, it could stall the growth of a bustling, transactional ecosystem.
Let’s be fair: hodling has been a winning play for many, turning small investments into fortunes. It’s a stretch to demand these pioneers shoulder the adoption burden alone. As Bitcoin weaves into the fabric of commerce—think businesses accepting it or workers earning it—transactional demand will rise organically. Over time, this could nudge even the staunchest hodlers to spend a bit, striking a balance between saving and circulating.
Growth and Stability: A Natural Progression
Bitcoin’s Compound Annual Growth Rate (CAGR) offers another angle. As its market cap balloons, its explosive growth is likely to taper off—a standard pattern for any asset. This slowdown could usher in greater stability, a boon for its MOE ambitions. Less volatility means less risk when spending Bitcoin, paving the way for it to move beyond investment portfolios and into wallets for everyday use.
This shift could redefine Bitcoin’s story, transforming it from a rollercoaster ride to a dependable currency. Voices like Jeff Booth and Jack Dorsey argue that MOE success is the key to sustaining Bitcoin’s SOV status. In short, while SOV lit the fuse, MOE could keep the fire burning.
The Blueprint: Steps to a Bitcoin Standard
So, how does Bitcoin ascend to world reserve status and birth a Bitcoin standard? Here’s a five-step vision:
1. SOV Momentum: Bitcoin’s allure as an inflation hedge and wealth preserver keeps drawing in holders, boosting its market cap and global clout.
2. MOE Infrastructure: Innovations like the Lightning Network must deliver fast, cheap transactions, making Bitcoin a practical choice for daily spending.
3. Value Stability: As adoption spreads and the market matures, Bitcoin’s price swings dampen, earning trust from users and merchants alike.
4. MOE Takeoff: With better tools and steadier value, Bitcoin becomes a go-to for transactions, amplifying its worth through a powerful network effect.
5. Global Crown: Governments and central banks start holding Bitcoin in reserves, using it for trade and settlements, cementing its place as the world’s reserve currency.
This isn’t a cakewalk. Scalability bottlenecks, regulatory pushback, and rival cryptocurrencies loom large. But if Bitcoin can clear these obstacles, it could become the backbone of global finance.
Harmony Over Division: SOV and MOE Together
Here’s the crux: SOV and MOE aren’t at odds—they’re partners in Bitcoin’s rise. Holding Bitcoin safeguards its scarcity and value; spending it spreads its reach and usefulness. Both are vital for the long haul.
At this pivotal moment, the Bitcoin community must rally around a dual-purpose ethos. We can:
• Educate: Help newcomers grasp Bitcoin’s twin roles as SOV and MOE.
• Innovate: Back tech that makes Bitcoin spending as easy as swiping a card.
• Talk: Host open forums to wrestle with differences and find unity.
The Final Word: Our Collective Challenge
Bitcoin’s shot at becoming the world’s reserve currency—and forging a Bitcoin standard—is as exhilarating as it is daunting. Its Store of Value roots have set the stage, but its Medium of Exchange potential will decide if it can topple fiat and redefine money itself.
The path is long, but the prize is transformative. By embracing both SOV and MOE, we can propel Bitcoin to new heights. Let’s grab this chance, dive into the debate, and build a future where Bitcoin leads the charge.
Your Turn: What’s the best way forward for Bitcoin? Should we lean harder into SOV, push MOE, or blend the two? Drop your thoughts below an

2025-05-29 12:26:43Saturday 9AM It’s a chilly Saturday morning in Warsaw, and I don’t want to get out of bed. This is not because of the hangover; it’s because I feel like a failure.
The first day of Bitcoin FilmFest was a whirlwind of workshops, panels and running between stages. The pitch competition did not go my way. Another ‘pitching rabbit’ (an actual experienced film-maker) was selected to win the €3,000 of funding.
Rather than get up and search for coffee, I replay the scenes in my head. What could I have done differently? Will investors ever believe in me: I’m just a writer with no contacts in the industry. Do I have what it takes to produce a film?
Eventually, I haul myself out of bed and walk to Amondo, the festival’s morning HQ (and technically, the smallest cinema in Europe). Upon arrival, I find Bitcoin psychonaut Ioni Appelberg holding court in front of around a dozen enraptured disciples. Soon, the conversation spills out to the street to free up space for more workshops.
I attend a talk on film funding, then pay for coffee using bitcoin. I see familiar faces from the two previous nights. We compare notes on Friday night and check the day’s schedule. The morning clouds burn off, and things feel a little brighter.
The afternoon session begins just a few blocks away in the towering Palace of Culture and Science. My role in today's proceedings is to present my freedom fiction project, 21 Futures, on the community stage. Other presentations range from rap videos and advice on finding jobs in bitcoin to hosting ‘Bitcoin Walks’. This is how we are fixing the culture.
Saturday 8PM I feel a tap on my shoulder. ‘Excuse me, Mr. Philip. Your car is waiting. The Producers’ Dinner is starting soon’.
What? Me, a producer? I’ve been taking part in some panels and talks, but I assumed my benefits as a guest were limited to a comped ticket and generous goodie bag.
Soon, I am sharing a taxi with a Dubai-based journalist, a Colombian director, and the cypherpunk sponsor of the pitch competition I didn’t win.
The pierogies I dreamed of earlier that day somehow manifest (happy endings do exist), and we enjoy a raucous dinner including obligatory slivovitz.
Sunday 2AM The last few hours of blur include a bracing city-bike ride in a crew of nine attendees back to the Palace of Culture, chatting with a fellow bitcoin meetup organiser, and vaguely promising to attend a weekend rave with a crew of Polish artists and musicians on the outskirts of London.
I leave the party while it’s still in full swing. In five hours, I have to wake up to complete my Run for Hal in Marshal Edward Rydz-Śmigły Park.
Thursday 9PM The festival kicks off in Samo Centrum on Pizza Day. I arrive in a taxi straight from a cramped flight (fix the airlines!), having not eaten for around ten hours.
The infectious sounds of softly spoken Aussie bitrocker Roger9000 pound into the damp night. I’m three beers in, being presented by the organisers to attendees like a (very tall) show pony. I try to explain more about my books, my publishing connections, my short film.
When I search for the food I ordered an hour ago, I find it has been given away. The stern-faced Polish pizza maker shrugs. ‘You not here.’
I’m so hungry I could cry (six hours of Ryanair can do that to a man). And then, a heroic Czech pleb donates half a pizza to me. Side note: this same heroic pleb accidentally locked me out of my film-funds while trying to fix a wallet bug on Sunday night.
I step out into the rain. Roger9000 reminds us we should have laser eyes well past 100k. I take a bite of pizza and life tastes good.
The Films Side events, artists, late nights, and pitcher’s regret is all well and good, but what of the films?
My highlights included Golden Rabbit winner No More Inflation — a moving narrative with interviews from two dozen economists, visionaries, and inflation survivors.
Hotel Bitcoin, was a surprisingly funny comedy romp about a group of idiots who happen across a valuable laptop.
Revolución Bitcoin — an approachable and thorough documentary aimed to bring greater adoption in the Spanish-speaking world.
And, as a short-fiction guy, I enjoyed the short films The Man Who Wouldn’t Cry, a visit to New York’s only Somali restaurant in Finding Home.
Sunday 7PM The award ceremony has just finished. I head to Amondo for the final time to pay for mojitos in bitcoin and say goodbye to newly made friends. I feel like I’ve met almost everyone in attendance. Are you going to BTC Prague?!? we ask as we part ways.
Of course, the best thing about any festival is the people, and BFF25 had a cast of characters worthy of any art house flick:
- The bright-eyed and confident frontwoman of the metal band Scardust
- A nostr-native artist selling his intricate canvases to the highest zapper
- A dreadlocked DJ who wears a pair of flying goggles on his head at all times
- An affable British filmmaker explaining the virtues of the word ‘chucklesome’
- A Duracell-powered organiser who seems to know every song, person, film, book, and guest at the festival.
Warsaw itself feels like it has a role to play, too. Birdsong and green parks contrast the foreboding Communist-era architecture. The weather changes faster than my mood — heavy greys transform to bright sunshine. The roads around the venue close on Sunday for a political rally. And there we are in the middle, watching our bitcoin films.
Tuesday 10AM I’m at home now, squinting at my email inbox and piles of washing, wondering when the hell I’ll find time. The festival Telegram group is still buzzing with activity. Side events like martial arts tutorials, trips to a shooting range, boat tours. 5AM photos of street graffiti, lost and found items, and people asking ‘is anyone still around?’
This was not just a film festival. BFF is truly a celebration of culture — Art. Books. Comedy. Music. Video. Talk. Connection.
All this pure signal has lifted my spirits so much that despite me being a newbie filmmaker, armed only with a biro, a couple of powerpoints and a Geyser fund page, I know I will succeed in my mission. It turns out you can just film things.
You may have attended bitcoin conferences before — you know, the ones with ‘fireside chats’, VIP areas, and overpriced merch. Bitcoin FilmFest is a moment in time. We are fixing the culture, year after year, until art can flourish again.
As fellow author Aaron Koenig commented during a panel session, ‘In twenty years, we won’t be drawing laser eyes and singing about honey badgers. Our grandchildren won’t understand the change we went through.’
Would I do it all again? Of course!
Join me next June in Warsaw.
I’ll be the tall one presenting his short animation premiere.
Philip Charter is a full-time writer and part-time cat herder. As well as writing for bitcoin founders and companies, he runs the 21 Futures fiction project.

2025-04-30 12:10:06前回の続きです。
特に「Snortで試験的にノート単位に投げ銭できる機能」について。実は記事書いた直後にリリースされて慌ててw追記してたんですが追い付かないということで別記事にしました。
今回のここがすごい!
「Snortで試験的にノート単位に投げ銭できる機能」では一つブレイクスルーが起こっています。それは「ウォレットにインボイスを放り投げた後に払い込み完了を提示できる」ようになったことです。これによりペイメントのライフサイクルが一通りカバーされたことになります。
Snortの画面
なにを当たり前のことをという向きもあるかもしれませんが、Nostrクライアントで払い込み完了を追跡することはとても難しいです。基本的にNostrとLNウォレットはまったく別のアプリケーションで両者の間を繋ぐのはインボイス文字列だけです。ウォレットもNostrからキックされずに、インボイス文字列をコピペするなりQRコードで読み取ったものを渡されるだけかもしれません。またその場でリアルタイムに処理される前提もありません。
なのでNostrクライアントでその後をトラックすることは難しく、これまではあくまで請求書を送付したり(LNインボイス)振り込み口座を提示する(LNアドレス)という一方的に放り投げてただけだったわけです。といっても魔法のようにNostrクライアントがトラックできるようになったわけではなく、今回の対応方法もインボイスを発行/お金を振り込まれるサービス側(LNURL)にNostrカスタマイズを入れさせるというものになります。
プロポーザルの概要について
前回の記事ではよくわからんで終わっていましたが、当日夜(日本時間)にスペックをまとめたプロポーザルも起こされました(早い!)。LNURLが、Nostr用のインボイスを発行して、さらにNostrイベントの発行を行っていることがポイントでした。名称は"Lightning Zaps"で確定のようです。プロポーザルは、NostrとLNURLの双方の発明者であるfiatjaf氏からツッコミが入り、またそれが妥当な指摘のために、エンドポイントURLのインターフェースなどは変わりそうなのですが、概要はそう変わらないだろうということで簡単にまとめてみます。
全体の流れ
図は、Nostrクライアント上に提示されているLNアドレスへ投げ銭が開始してから、Nostrクライアント上に払い込み完了したイベントが表示されるまでの流れを示しています。
- 投げ銭の内容が固まったらNostrイベントデータを添付してインボイスの発行を依頼する
- 説明欄にNostr用のデータを記載したインボイスを発行して返却する
- Nostrクライアントで提示されたインボイスをユーザーが何かしらの手段でウォレットに渡す
- ウォレットがLNに支払いを実行する
- インボイスの発行者であるLNURLが管理しているLNノードにsatoshiが届く
- LNURLサーバが投げ銭成功のNostrイベントを発行する
- Nostrクライアントがイベントを受信して投げ銭履歴を表示する
特にポイントとなるところを補足します。
対応しているLNアドレスの識別
LNアドレスに投げ銭する場合は、LNアドレスの有効状態やインボイス発行依頼する先の情報を
https://[domain]/.well-known/lnurlp/[username]
から取得しています。そのレスポンス内容にNostr対応を示す情報を追加しています。ただし、ここに突っ込み入っていてlnurlp=LNURL Payから独立させるためにzaps専用のエンドポイントに変わりそうです。(2/15 追記 マージされましたが変更無しでした。PRのディスカッションが盛り上がっているので興味ある方は覗いてみてください。)インボイスの説明欄に書き込むNostrイベント(kind:9734)
これは投げ銭する側のNostrイベントです。投げ銭される者や対象ノートのIDや金額、そしてこのイベントを作成している者が投げ銭したということを「表明」するものになります。表明であって証明でないところは、インボイスを別の人が払っちゃう事態がありえるからですね。この内容をエンクリプトするパターンも用意されていたが複雑になり過ぎるという理由で今回は外され追加提案に回されました。また、このイベントはデータを作成しただけです。支払いを検知した後にLNURLが発行するイベントに添付されることになります。そのため投げ銭する者にちゃんと届くように作成者のリレーサーバリストも書き込まれています。
支払いを検知した後に発行するNostrイベント(kind:9735)
これが実際にNostrリレーサーバに発行されるイベントです。LNURL側はウォッチしているLNノードにsatoshiが届くと、インボイスの説明欄に書かれているNostrイベントを取り出して、いわば受領イベントを作成して発行します。以下のようにNostイベントのkind:9734とkind:9735が親子になったイベントとなります。
json { "pubkey": "LNURLが持っているNostrアカウントの公開鍵", "kind": 9735, "tags": [ [ "p", "投げ銭された者の公開鍵" ], [ "bolt11", "インボイスの文字列lnbc〜" ], [ "description", "投げ銭した者が作成したkind:9734のNostrイベント" ], [ "preimage", "インボイスのpreimage" ] ], }
所感
とにかくNostrクライアントはLNノードを持たないしLNプロトコルとも直接喋らずにインボイス文字列だけで取り扱えるようになっているところがおもしろいと思っています。NostrとLNという二つのデセントライズドなオープンプロトコルが協調できていますし、前回も述べましたがどんなアプリでも簡単に真似できます。
とはいえ、さすがに払込完了のトラックは難しく、今回はLNURL側にそのすり合わせの責務が寄せられることになりました。しかし、LNURLもLNの上に作られたオープンプロトコル/スペックの位置付けになるため、他のLNURLのスペックに干渉するという懸念から、本提案のNIP-57に変更依頼が出されています。LN、LNURL、Nostrの3つのオープンプロトコルの責務分担が難しいですね。アーキテクチャ層のスタックにおいて3つの中ではNostrが一番上になるため、Nostrに相当するレイヤーの他のwebサービスでやるときはLNプロトコルを喋るなりLNノードを持つようにして、今回LNURLが寄せられた責務を吸収するのが無難かもしれません。
また、NIP-57の変更依頼理由の一つにはBOLT-12を見越した抽象化も挙げられています。他のLNURLのスペックを削ぎ落としてzapsだけにすることでBOLT-12にも載りやすくなるだろうと。LNURLの多くはBOLT-12に取り込まれる運命なわけですが、LNアドレス以外の点でもNostrではBOLT-12のOfferやInvoiceRequestのユースケースをやりたいという声が挙がっているため、NostrによりBOLT-12が進む展開もありそうだなあ、あってほしい。

2025-05-29 12:02:57Since 2019, the United States has been the country with the highest number of recorded cases, but Europe remains the most affected region.
According to a Binance report, the United States is the country that has recorded the greatest number of crypto-related kidnapping cases since 2019, despite a recent increase in incidents in France.
At the regional level, however, Europe remains the area with the highest number of crypto-related kidnappings: 59 cases over six years. During the same period, North America — which includes the United States and Canada — recorded 48 cases. Particularly notable is the data concerning the entire Asian continent, where 62 cases of crypto-related kidnappings have been documented, most of which are concentrated in Southeast Asian countries.
France emerges as a concerning hotspot for crypto kidnappings, with six recent cases, three of which have already occurred in 2025.
Source: Binance
The primary targets of these kidnappings include executives of crypto companies, professional traders, exchange employees, and entrepreneurs in the sector. Family members and close associates of victims are often targeted as well. An emerging phenomenon involves tourists suspected of possessing large amounts of cryptocurrency funds.
Kidnapping cases in 2025
The year 2025 has already seen particularly serious episodes of kidnappings linked to the digital asset world. The most notable case involved David Balland, co-founder of Ledger, and his wife, who were abducted from their residence in France earlier this January. The incident drew international attention from both the crypto industry and law enforcement agencies.
Another attempt took place in Paris, where armed men tried to kidnap the daughter and granddaughter of the CEO of the French exchange Paymium. Overseas, in New York, police arrested 37-year-old John Woeltz after discovering that an Italian tourist had been held captive and mistreated for weeks in a luxury Manhattan apartment.
Binance highlights a direct correlation between the price trend of Bitcoin and the increase in kidnappings. Since Bitcoin reached new all-time highs this year, attacks involving physical threats have also increased proportionally, the exchange suggests.
Source: Binance
In 2025 alone, at least 15 kidnapping episodes have already been documented, many involving ransom demands denominated in bitcoin.

Nostrクライアントは多種ありますがメジャーなものはだいたいLNの支払いが用意されています。現時点でどんな組み込み方法になっているか調べました。この記事では主にSnortを対象にしています。
LN活用場面
大きくLNアドレスとLNインボイスの2つの形式があります。
1. LNアドレスで投げ銭をセットできる
LNURLのLNアドレスをセットすると、プロフィールやノート(ツイートに相当)からLN支払いができます。別クライアントのastralなどではプリミティブなLNURLの投げ銭形式
lnurl1dp68~
でもセットできます。[追記]さらに本日、Snortで試験的にノート単位に投げ銭できる機能が追加されています。
2. LNインボイスが投稿できる
投稿でLNインボイスを貼り付ければ上記のように他の発言と同じようにタイムラインに流れます。Payボタンを押すと各自の端末にあるLNウォレットが立ち上がります。
3. DMでLNインボイスを送る
メッセージにLNインボイスが組み込まれているという点では2とほぼ同じですが、ユースケースが異なります。発表されたばかりですがリレーサーバの有料化が始まっていて、その決済をDMにLNインボイスを送付して行うことが試されています。2だとパブリックに投稿されますが、こちらはプライベートなので購入希望者のみにLNインボイスを届けられます。
おまけ: Nostrのユーザ名をLNアドレスと同じにする
直接は関係ないですが、Nostrはユーザー名をemail形式にすることができます。LNアドレスも自分でドメイン取って作れるのでNostrのユーザー名と投げ銭のアドレスを同じにできます。
LNウォレットのAlbyのドメインをNostrのユーザ名にも活用している様子 [Not found]
実装方法
LNアドレスもLNインボイスも非常にシンプルな話ですが軽くまとめます。 Snortリポジトリ
LNアドレス
- セットされたLNアドレスを分解して
https://[domain]/.well-known/lnurlp/[username]
にリクエストする - 成功したら投げ銭量を決めるUIを提示する
- Get Inoviceボタンを押したら1のレスポンスにあるcallbackにリクエストしてインボイスを取得する
- 成功したらPayボタンを提示する
LNインボイス
- 投稿内容がLNインボイス識別子
lnbc10m〜
だとわかると、識別子の中の文字列から情報(金額、説明、有効期限)を取り出し、表示用のUIを作成する - 有効期限内だったらPayボタンを提示し、期限が切れていたらExpiredでロックする
支払い
Payボタンを押された後の動きはアドレス、インボイスとも同じです。
- ブラウザでWebLN(Albyなど)がセットされていて、window.weblnオブジェクトがenableになっていると、拡張機能の支払い画面が立ち上がる。クライアント側で支払い成功をキャッチすることも可能。
- Open Walletボタンを押すと
lightning:lnbc10m~
のURI形式でwindow.openされ、Mac/Windows/iPhone/Androidなど各OSに応じたアプリケーション呼び出しが行われ、URIに対応しているLNウォレットが立ち上がる
[追記]ノート単位の投げ銭
Snort周辺の数人(strike社員っぽい人が一人いて本件のメイン実装している)で試験的にやっているようで現時点では実装レベルでしか詳細わかりませんでした。strikeのzapといまいち区別が付かなかったのですが、実装を見るとnostrプロトコルにzapイベントが追加されています。ソースコメントではこの後NIP(nostr improvement proposal)が起こされるようでかなりハッキーです。zap=tipの方言なんでしょうか?
ノートやプロフィールやリアクションなどに加えて新たにnostrイベントに追加しているものは以下2つです。
- zapRequest 投げ銭した側が対象イベントIDと量を記録する
- zapReceipt 投げ銭を受け取った側用のイベント
一つでできそうと思ったけど、nostrは自己主権のプロトコルでイベント作成するには発行者の署名が必須なので2つに分かれているのでしょう。
所感
現状はクライアントだけで完結する非常にシンプルな方法になっています。リレーサーバも経由しないしクライアントにLNノードを組み込むこともしていません。サードパーティへのhttpリクエストやローカルのアプリに受け渡すだけなので、実はどんな一般アプリでもそんなに知識もコストも要らずにパッとできるものです。
現状ちょっと不便だなと思っていることは、タイムラインに流れるインボイスの有効期限内の支払い済みがわからないことです。Payボタンを押してエラーにならないとわかりません。ウォレットアプリに放り投げていてこのトレースするためには、ウォレット側で支払い成功したらNostrイベントを書き込むなどの対応しない限りは、サービス側でインボイスを定期的に一つ一つLNに投げてチェックするなどが必要だと思われるので、他のサービスでマネするときは留意しておくとよさそうです。
一方で、DMによるLNインボイス送付は活用方法が広がりそうな予感があります。Nostrの公開鍵による本人特定と、LNインボイスのメモ欄のテキスト情報による突き合わせだけでも、かんたんな決済機能として用いれそうだからです。もっとNostrに判断材料を追加したければイベント追加も簡単にできることをSnortが示しています。とくにリレーサーバ購読やPROメニューなどのNostr周辺の支払いはやりやすそうなので、DM活用ではなくなにかしらの決済メニューを搭載したNostrクライアントもすぐに出てきそう気がします。

LNの手数料の適正水準はどう見積もったらいいだろうか?ルーティングノードの収益性を算出するためにはどうアプローチすればよいだろうか?本記事ではルーティングノード運用のポジションに立ち参考になりそうな数値や計算式を整理する。
個人的な感想を先に書くと以下となる。
- 現在の手数料市場は収益性が低くもっと手数料が上がった方が健全である。
- 他の決済手段と比較すると、LN支払い料金は10000ppm(手数料1%相当)でも十分ではないか。4ホップとすると中間1ノードあたり2500ppmである。
- ルーティングノードの収益性を考えると、1000ppmあれば1BTC程度の資金で年利2.8%になり半年で初期費用回収できるので十分な投資対象になると考える。
基本概念の整理
LNの料金方式
- LNの手数料は送金額に応じた料率方式が主になる。(基本料金の設定もあるが1 ~ 0 satsが大半)
- 料率単位のppm(parts per million)は、1,000,000satsを送るときの手数料をsats金額で示したもの。
- %での手数料率に変換すると1000ppm = 0.1%になる。
- 支払い者が払う手数料はルーティングに参加した各ノードの手数料の合計である。本稿では4ホップ(経由ノードが4つ)のルーティングがあるとすれば、各ノードの取り分は単純計算で1/4とみなす。
- ルーティングノードの収益はアウトバウンドフローで発生するのでアウトバウンドキャパシティが直接的な収益資源となる。
LNの料金以外のベネフィット
本稿では料金比較だけを行うが実際の決済検討では以下のような料金以外の効用も忘れてはならない。
- Bitcoin(L1)に比べると、料金の安さだけでなく、即時確定やトランザクション量のスケールという利点がある。
- クレジットカードなどの集権サービスと比較した特徴はBitcoin(L1)とだいたい同じである。
- 24時間365日利用できる
- 誰でも自由に使える
- 信頼する第三者に対する加盟や審査や手数料率などの交渉手続きが要らない
- 検閲がなく匿名性が高い
- 逆にデメリットはオンライン前提がゆえの利用の不便さやセキュリティ面の不安さなどが挙げられる。
現在の料金相場
- ルーティングノードの料金設定
- sinkノードとのチャネルは500 ~ 1000ppmが多い。
- routing/sourceノードとのチャネルは0 ~ 100ppmあたりのレンジになる。
- リバランスする場合もsinkで収益を上げているならsink以下になるのが道理である。
- プロダクト/サービスのバックエンドにいるノードの料金設定
- sinkやsourceに相当するものは上記の通り。
- 1000〜5000ppmあたりで一律同じ設定というノードもよく見かける。
- ビジネスモデル次第で千差万別だがアクティブと思われるノードでそれ以上はあまり見かけない。
- 上記は1ノードあたりの料金になる。支払い全体では経由したノードの合計になる。
料金目安
いくつかの方法で参考数字を出していく。LN料金算出は「支払い全体/2ホップしたときの1ノードあたり/4ホップしたときの1ノードあたり」の三段階で出す。
類推方式
決済代行業者との比較
- Squareの加盟店手数料は、日本3.25%、アメリカ2.60%である。
- 参考資料 https://www.meti.go.jp/shingikai/mono_info_service/cashless_payment/pdf/20220318_1.pdf
3.25%とするとLNでは「支払い全体/2ホップしたときの1ノードあたり/4ホップしたときの1ノードあたり」でそれぞれ
32,500ppm/16,250ppm/8,125ppm
になる。スマホのアプリストアとの比較
- Androidのアプリストアは年間売上高が100万USDまでなら15%、それ以上なら30%
- 参考資料https://support.google.com/googleplay/android-developer/answer/112622?hl=ja
15%とするとLNでは「支払い全体/2ホップしたときの1ノードあたり/4ホップしたときの1ノードあたり」でそれぞれ
150,000ppm/75,000ppm/37,500ppm
になる。Bitcoin(L1)との比較
Bitcoin(L1)は送金額が異なっても手数料がほぼ同じため、従量課金のLNと単純比較はできない。そのためここではLNの方が料金がお得になる目安を出す。
Bitcoin(L1)の手数料設定
- SegWitのシンプルな送金を対象にする。
- input×1、output×2(送金+お釣り)、tx合計222byte
- L1の手数料は、1sat/byteなら222sats、10sat/byteなら2,220sats、100sat/byteなら22,200sats。(単純化のためvirtual byteではなくbyteで計算する)
- サンプル例 https://www.blockchain.com/btc/tx/15b959509dad5df0e38be2818d8ec74531198ca29ac205db5cceeb17177ff095
L1相場が1sat/byteの時にLNの方がお得なライン
- 100ppmなら、0.0222BTC(2,220,000sats)まで
- 1000ppmなら、0.00222BTC(222,000sats)まで
L1相場が10sat/byteの時にLNの方がお得なライン
- 100ppmなら、0.222BTC(22,200,000sats)まで
- 1000ppmなら、0.0222BTC(2,220,000sats)まで
L1相場が100sat/byteの時にLNの方がお得なライン
- 100ppmなら、2.22BTC(222,000,000sats)まで
- 1000ppmなら、0.222BTC(22,200,000sats)まで
コスト積み上げ方式
ルーティングノードの原価から損益分岐点となるppmを算出する。事業者ではなく個人を想定し、クラウドではなくラズベリーパイでのノード構築環境で計算する。
費用明細
- BTC市場価格 1sat = 0.03円(1BTC = 3百万円)
初期費用
- ハードウェア一式 40,000円
- Raspberry Pi 4 8GB
- SSD 1TB
- 外付けディスプレイ
- チャネル開設のオンチェーン手数料 6.69円/チャネル
- 開設料 223sats
- 223sats * BTC市場価格0.03円 = 6.69円
固定費用
- 電気代 291.6円/月
- 時間あたりの電力量 0.015kWh
- Raspberry Pi 4 電圧5V、推奨電源容量3.0A
- https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#power-supply
- kWh単価27円
- 0.015kWh * kWh単価27円 * 1ヶ月の時間720h = 291.6円
損益分岐点
- 月あたりの電気代を上回るために9,720sats(291.6円)/月以上の収益が必要である。
- ハードウェア費用回収のために0.01333333BTC(133万sats) = 40,000円の収益が必要である。
費用回収シナリオ例
アウトバウンドキャパに1BTCをデポジットしたAさんを例にする。1BTCは初心者とは言えないと思うが、このくらい原資を用意しないと費用回収の話がしづらいという裏事情がある。チャネル選択やルーティング戦略は何もしていない仮定である。ノード運用次第であることは言うまでもないので今回は要素や式を洗い出すことが主目的で一つ一つの変数の値は参考までに。
変数設定
- インバウンドを同額用意して合計キャパを2BTCとする。
- 1チャネルあたり5m satsで40チャネル開設する。
- チャネル開設費用 223sats * 40チャネル = 8,920sats
- 初期費用合計 1,333,333sats + 8,920sats = 1,342,253sats
- 一回あたり平均ルーティング量 = 100,000sats
- 1チャネルあたり平均アウトバウンド数/日 = 2
- 1チャネルあたり平均アウトバウンドppm = 50
費用回収地点
- 1日のアウトバウンド量は、 40チャネル * 2本 * 100,000sats = 8m sats
- 手数料収入は、8m sats * 0.005%(50ppm) = 400sats/日。月換算すると12,000sats/月
- 電気代を差し引くと、12,000sats - 電気代9,720sats =月収益2,280sats(68.4円)
- 初期費用回収まで、1,342,253sats / 2,280sats = 589ヵ月(49年)
- 後述するが電気代差引き前で年利0.14%になる。
理想的なppm
6ヵ月での初期費用回収を目的にしてアウトバウンドppmを求める。
- ひと月あたり、初期費用合計1,342,253sats / 6ヵ月 + 電気代9,720sats = 233,429sats(7,003円)の収益が必要。
- 1日あたり、7,781sats(233円)の収益
- その場合の平均アウトバウンドppmは、 7,781sats(1日の収益量) / 8m sats(1日のアウトバウンド量) * 1m sats(ppm変換係数) = 973ppm
他のファイナンスとの比較
ルーティングノードを運用して手数料収入を得ることは資産運用と捉えることもできる。レンディングやトレードなどの他の資産運用手段とパフォーマンス比較をするなら、デポジットしたアウトバウンドキャパシティに対する手数料収入をAPY換算する。(獲得した手数料はアウトバウンドキャパシティに積み重ねられるので複利と見做せる)
例としてLNDg(v1.3.1)のAPY算出計算式を転載する。見ての通り画面上の表記はAPYなのに中身はAPRになっているので注意だが今回は考え方の参考としてこのまま採用する。
年換算 = 365 / 7 = 52.142857 年利 = (7dayの収益 * 年換算) / アウトバウンドのキャパシティ
例えば上記のAさんの費用回収シナリオに当てはめると以下となる。
年利 0.14% = (400sats * 7日 * 年換算)/ 100m sats
電気代を差し引くと 76sats/日となり年利0.027%
もし平均アウトバウンド1000ppmになると8,000sats/日なので年利2.9%になる。 この場合、電気代はほぼ1日で回収されるため差し引いても大差なく7,676sats/日で年利2.8%になる。
考察
以上、BTC市場価格や一日のアウトバウンド量といった重要な数値をいくつか仮置きした上ではあるが、LN手数料の適正水準を考えるための参考材料を提示した。
まず、現在のLNの料金相場は他の決済手段から比べると圧倒的に安いことがわかった。1%でも競争力が十分ありそうなのに0.1%前後で送金することが大半である。
健全な市場発展のためには、ルーティングノードの採算が取れていることが欠かせないと考えるが、残念ながら現在の収益性は低い。ルーティングノードの収益性は仮定に仮定を重ねた見積もりになるが、平均アウトバウンドが1000ppmでようやく個人でも参入できるレベルになるという結論になった。ルーティングノードの立場に立つと、現在の市場平均から大幅な上昇が必要だと考える。
手数料市場は競争のためつねに下方圧力がかかっていて仕様上で可能な0に近づいている。この重力に逆らうためには、1. 需要 > 供給のバランスになること、2. 事業用途での高額買取のチャネルが増えること、の2つの観点を挙げる。1にせよ2にせよネットワークの活用が進むことで発生し、手数料市場の大きな変動機会になるのではないか。他の決済手段と比較すれば10000ppm、1チャネル2500ppmあたりまでは十分に健全な範囲だと考える。

2025-05-29 12:02:46Ed Suman, a 67-year-old retired artist who helped create large sculptures like Jeff Koons’ Balloon Dog, reportedly lost his entire life savings — over $2M in digital assets — in a sophisticated scam.
The incident is believed to be tied to the major data breach at Coinbase, one of the world’s largest digital asset exchanges.
Suman’s story is part of a bigger wave of attacks on digital asset holders using stolen personal info, and has triggered lawsuits, regulatory concerns and questions about digital security in the Bitcoin space.
In March 2025, Suman got a text message about suspicious activity on his Coinbase account. After Suman reported he was unaware of any unauthorized activity regarding his account, he got a call from a man who introduced himself as Brett Miller from Coinbase Security.
The guy sounded legit — he knew Suman’s setup, including that he used a Trezor Model One hardware wallet, a device meant to keep bitcoin and other digital assets offline and safe.
Suman told Bloomberg the guy knew everything, including the exact amount of digital assets he had.
The attacker persuaded Suman that his Trezor One hardware wallet and its funds were at risk and walked him through a “security procedure” that involved entering his seed phrase into a website that looked exactly like Coinbase, in order to “link his wallet to Coinbase”.
Nine days later, another guy called and repeated the process, saying the first one didn’t work.
And then, all of Suman’s digital assets — 17.5 bitcoin and 225 ether — were gone. At the time, bitcoin was around $103,000 and ether around $2,500, so the stolen stash was worth over $2 million.
Suman turned to digital assets after retiring from a decades-long art career. He stored his assets in cold storage to avoid the risks of online exchanges. He thought he did everything right.
Suman’s attackers didn’t pick his name out of a hat.
It looks like his personal info may have been leaked in the major breach at Coinbase. The company confirmed on May 15 that some of its customer service reps in India were bribed to access internal systems and steal customer data.
The stolen data included names, phone numbers, email addresses, balances and partial Social Security numbers.
According to Coinbase’s filing with the U.S. Securities and Exchange Commission, the breach may have started as early as January and affected nearly 1% of the company’s active monthly users — tens of thousands of people.
Hackers demanded $20M from Coinbase to keep the breach quiet but the company refused to pay. Coinbase says it fired the compromised agents and is setting aside $180M to $400M to reimburse affected users.
But so far, Suman hasn’t been told if he’ll be reimbursed.
Since the breach was disclosed, Coinbase has been hit with at least six lawsuits.
The lawsuits claim the company failed to protect user data and handled the aftermath poorly. One lawsuit filed in New York federal court on May 16 says Coinbase’s response was “inadequate, fragmented, and delayed.”
“Users were not promptly or fully informed of the compromise,” the complaint states, “and Coinbase did not immediately take meaningful steps to mitigate further harm.”
Some lawsuits are seeking damages, others are asking Coinbase to purge user data and improve its security. Coinbase has not commented on the lawsuits but pointed reporters to a blog post about its response.
Suman’s case is a cautionary tale across the Bitcoin world. He used a hardware wallet (considered the gold standard of Bitcoin security) and was still tricked through social engineering. Even the strongest security is useless if you don’t understand how Bitcoin works.
It’s never too early for Bitcoiners to start learning more about Bitcoin, especially on how to keep their stash safe. And the first lesson is “never ever share your seed phrase with anyone”.

2025-05-28 01:11:43In this second installment of The Android Elite Setup tutorial series, we will cover installing the nostr:npub10r8xl2njyepcw2zwv3a6dyufj4e4ajx86hz6v4ehu4gnpupxxp7stjt2p8 on your #Android device and browsing for apps you may be interested in trying out.
Since the #Zapstore is a direct competitor to the Google Play Store, you're not going to be able to find and install it from there like you may be used to with other apps. Instead, you will need to install it directly from the developer's GitHub page. This is not a complicated process, but it is outside the normal flow of searching on the Play Store, tapping install, and you're done.
Installation
From any web browser on your Android phone, navigate to the Zapstore GitHub Releases page and the most recent version will be listed at the top of the page. The .apk file for you to download and install will be listed in the "Assets."
Tap the .apk to download it, and you should get a notification when the download has completed, with a prompt to open the file.
You will likely be presented with a prompt warning you that your phone currently isn't allowed to install applications from "unknown sources." Anywhere other than the Play Store is considered an "unknown source" by default. However, you can manually allow installation from unknown sources in the settings, which the prompt gives you the option to do.
In the settings page that opens, toggle it to allow installation from this source, and you should be prompted to install the application. If you aren't, simply go to your web browser's downloads and tap on the .apk file again, or go into your file browser app and you should find the .apk in your Downloads folder.
If the application doesn't open automatically after install, you will find it in your app drawer.
Home Page
Right at the top of the home page in the Zapstore is the search bar. You can use it to find a specific app you know is available in the Zapstore.
There are quite a lot of open source apps available, and more being added all the time. Most are added by the Zapstore developer, nostr:npub1wf4pufsucer5va8g9p0rj5dnhvfeh6d8w0g6eayaep5dhps6rsgs43dgh9, but some are added by the app developers themselves, especially Nostr apps. All of the applications we will be installing through the Zapstore have been added by their developers and are cryptographically signed, so you know that what you download is what the developer actually released.
The next section is for app discovery. There are curated app collections to peruse for ideas about what you may want to install. As you can see, all of the other apps we will be installing are listed in nostr:npub1wf4pufsucer5va8g9p0rj5dnhvfeh6d8w0g6eayaep5dhps6rsgs43dgh9's "Nostr" collection.
In future releases of the Zapstore, users will be able to create their own app collections.
The last section of the home page is a chronological list of the latest releases. This includes both new apps added to the Zapstore and recently updated apps. The list of recent releases on its own can be a great resource for discovering apps you may not have heard of before.
Installed Apps
The next page of the app, accessed by the icon in the bottom-center of the screen that looks like a clock with an arrow circling it, shows all apps you have installed that are available in the Zapstore. It's also where you will find apps you have previously installed that are ready to be updated. This page is pretty sparse on my test profile, since I only have the Zapstore itself installed, so here is a look at it on my main profile:
The "Disabled Apps" at the top are usually applications that were installed via the Play Store or some other means, but are also available in the Zapstore. You may be surprised to see that some of the apps you already have installed on your device are also available on the Zapstore. However, to manage their updates though the Zapstore, you would need to uninstall the app and reinstall it from the Zapstore instead. I only recommend doing this for applications that are added to the Zapstore by their developers, or you may encounter a significant delay between a new update being released for the app and when that update is available on the Zapstore.
Tap on one of your apps in the list to see whether the app is added by the developer, or by the Zapstore. This takes you to the application's page, and you may see a warning at the top if the app was not installed through the Zapstore.
Scroll down the page a bit and you will see who signed the release that is available on the Zapstore.
In the case of Primal, even though the developer is on Nostr, they are not signing their own releases to the Zapstore yet. This means there will likely be a delay between Primal releasing an update and that update being available on the Zapstore.
Settings
The last page of the app is the settings page, found by tapping the cog at the bottom right.
Here you can send the Zapstore developer feedback directly (if you are logged in), connect a Lightning wallet using Nostr Wallet Connect, delete your local cache, and view some system information.
We will be adding a connection to our nostr:npub1h2qfjpnxau9k7ja9qkf50043xfpfy8j5v60xsqryef64y44puwnq28w8ch wallet in part 5 of this tutorial series.
For the time being, we are all set with the Zapstore and ready for the next stage of our journey.

Happy 🍕 Day's Present
まだ邦訳版が出版されていませんがこれまでのシリーズと同じくGitHubにソースコードが公開されています。なんと、現在のライセンスでは個人使用限定なら翻訳や製本が可能です。Macで、翻訳にはPDFをインプットにできるDeepLを用いた環境で、インスタントに製本してKindleなどで読めるようにする方法をまとめました。
手順の概要
- Ruby環境を用意する
- PDF作成ツールをセットアップする
- GitHubのリポジトリを自分のPCにクローンする
- asciidocをPDFに変換する
- DeepLを節約するためにPDFを結合する
- DeepLで翻訳ファイルを作る
- 一冊に製本する
この手法の強み・弱み
翻訳だけならPDFを挟まなくてもGithubなどでプレビューできるコンパイル後のドキュメントの文章をコピーしてDeepLのWebツールにペーストすればよいですが、原著のペーパーブックで438ページある大容量です。熟練のコピペ職人でも年貢を納めて後進(機械やソフトウェア)に道を譲る刻ではないでしょうか?ただし、Pros/Consがあります。
Pros
- 一冊の本になるので毎度のコピペ作業がいらない
- Pizzaを食べながらタブレットやKindleで読める
- 図や表が欠落しない(プロトコルの手順を追った解説が多いため最大の動機でした)
- 2022/6/16追記: DeepLの拡張機能がアップデートされウェブページの丸ごと翻訳が可能になりました。よってウェブ上のgithubの図表付きページをそのまま翻訳できます。
Cons
- Money is power(大容量のためDeepLの有料契約が必要)
- ページを跨いだ文章が統合されずに不自然な翻訳になる(仕様です)
- ~~翻訳できない章が一つある(解決方法がないか調査中です。DeepLさんもっとエラーメッセージ出してくれ。Help me)~~ DeepLサポートに投げたら翻訳できるようになりました。
詳細ステップ
0.Ruby環境を用意する
asciidoctorも新しく入れるなら最新のビルドで良いでしょう。
1.PDF作成ツールをセットアップする
$ gem install asciidoctor asciidoctor-pdf $ brew install gs
2.GitHubのリポジトリを自分のPCにクローンする
どこかの作業ディレクトリで以下を実行する
$ git clone git@github.com:lnbook/lnbook.git $ cd lnbook
3.asciidocをPDFに変換する
ワイルドカードを用いて本文を根こそぎPDF化します。
$ asciidoctor-pdf 0*.asciidoc 1*.asciidoc
いろいろ解析の警告が出ますが、ソースのasciidocを弄んでいくなりawsomeライブラリを導入すれば解消できるはずです。しかし如何せん量が多いので心が折れます。いったん無視して"Done is better than perfect"精神で最後までやり切りましょう。そのままGO!
また、お好みに合わせて、htmlで用意されている装丁用の部品も準備しましょう。私は表紙のcover.htmlをピックしました。ソースがhtmlなのでasciidoctorを通さず普通にPDFへ変換します。https://qiita.com/chenglin/items/9c4ed0dd626234b71a2c
4.DeepLを節約するためにPDFを結合する
DeepLでは課金プラン毎に翻訳可能なファイル数が設定されている上に、一本あたりの最大ファイルサイズが10MBです。また、翻訳エラーになる章が含まれていると丸ごとコケます。そのためPDCAサイクルを回し、最適なファイル数を手探りで見つけます。以下が今回導出した解となります。
$ gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output_1.pdf 01_introduction.pdf 02_getting_started.pdf 03_how_ln_works.pdf 04_node_client.pdf 05_node_operations.pdf
$gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output_2_1.pdf 06_lightning_architecture.pdf 07_payment_channels.pdf 08_routing_htlcs.pdf
$gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output_2_2.pdf 09_channel_operation.pdf 10_onion_routing.asciidoc$ gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=output_3.pdf 11_gossip_channel_graph.pdf 12_path_finding.pdf 13_wire_protocol.pdf 14_encrypted_transport.pdf 15_payment_requests.pdf 16_security_privacy_ln.pdf 17_conclusion.pdf
5. DeepLで翻訳ファイルを作る
PDFファイルを真心を込めた手作業で一つ一つDeepLにアップロードしていき翻訳ファイルを作ります。ファイル名はデフォルトの
[originalName](日本語).pdf
のままにしています。6. 一冊に製本する
表紙 + 本文で作成する例です。
$ gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=mastering_ln_jp.pdf cover.pdf "output_1 (日本語).pdf" "output_2_1 (日本語).pdf" "output_2_2 (日本語).pdf" "output_3 (日本語).pdf"
コングラチュレーションズ🎉
あなたは『Mastering the Lightning Network』の日本語版を手に入れた!個人使用に限り、あとは煮るなり焼くなりEPUBなりkindleへ送信するなり好き放題だ。

2025-05-29 10:32:34This article gives an overview and comparison of the various funding sources that are available for LNbits.
LNbits is compatible with many Lightning Network wallets and can be on anything from a small VPS to a raspberry Pi on your home network or the LNbits SaaS platform.
Why your funding source matters
There are trade-offs between the various funding sources, for example funding LNbits using Strike requires the user to KYC themselves and has some privacy compromises versus funding LNbits from your own LND node. However the technical barrier to entry and node maintenance of using Strike is lower than using LND.
Self-custodial vs custodial connectors
Self-custodial Funding Sources
You run the node or service, keep the keys, and may need to manage LN channels. Good if you want control and have the skills to look after a server. Examples: LND (gRPC/REST), CoreLightning, Spark.
Self-custodial funding sources with an LSP
These funding sources offer a reasonable compromise between self-custody and some privacy trade offs. Examples: Phoenixd, Breez SDK, Boltz.
Custodial (or semi-custodial) funding sources
A third party runs the node. You plug LNbits into their API. Setup is quick and costs are low, but you trust the provider with your funds and privacy. Examples: Alby, OpenNode, Blink, ZBD, LNPay or another LNbits instance.
Funding sources compared
Below is a summary of the main options and how they stack up.
LNbits Lightning Network Funding Sources Comparison Table

2025-05-28 00:59:49Your identity is important to you, right? While impersonation can be seen in some senses as a form of flattery, we all would prefer to be the only person capable of representing ourselves online, unless we intentionally delegate that privilege to someone else and maintain the ability to revoke it.
Amber does all of that for you in the context of #Nostr. It minimizes the possibility of your private key being compromized by acting as the only app with access to it, while all other Nostr apps send requests to Amber when they need something signed. This even allows you to give someone temporary authority to post as you without giving them your private key, and you retain the authority to revoke their permissions at any time.
nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5 has provided Android users with an incredibly powerful tool in Amber, and he continues to improve its functionality and ease of use. Indeed, there is not currently a comparative app available for iOS users. For the time being, this superpower is exclusive to Android.
Installation
Open up the Zapstore app that you installed in the previous stage of this tutorial series.
Very likely, Amber will be listed in the app collection section of the home page. If it is not, just search for "Amber" in the search bar.
Opening the app's page in the Zapstore shows that the release is signed by the developer. You can also see who has added this app to one of their collections and who has supported this app with sats by zapping the release.
Tap "Install" and you will be prompted to confirm you are sure you want to install Amber.
Helpfully, you are informed that several other users follow this developer on Nostr. If you have been on Nostr a while, you will likely recognize these gentlemen as other Nostr developers, one of them being the original creator of the protocol.
You can choose to never have Zapstore ask for confirmation again with apps developed by nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5, and since we have another of his apps to install later in this tutorial series, I recommend you toggle this on. Then tap on "Trust greenart7c3 and install app."
Just like when you installed the Zapstore from their GitHub, you will be prompted to allow the Zapstore to install apps, since Android considers it an "unknown source."
Once you toggle this on and use the back button to get back to the Zapstore, Amber will begin downloading and then present a prompt to install the app. Once installed, you will see a prompt that installation was a success and you can now open the app.
From here, how you proceed will depend on whether you need to set up a new Nostr identity or use Amber with an existing private key you already have set up. The next section will cover setting up a new Nostr identity with Amber. Skip to the section titled "Existing Nostrich" if you already have an nsec that you would like to use with Amber.
New Nostrich
Upon opening the application, you will be presented with the option to use an existing private key or create a new Nostr account. Nostr doesn't really have "accounts" in the traditional sense of the term. Accounts are a relic of permissioned systems. What you have on Nostr are keys, but Amber uses the "account" term because it is a more familiar concept, though it is technically inaccurate.
Choose "Create a new Nostr account" and you will be presented with a screen telling you that your Nostr account is ready. Yes, it was really that easy. No email, no real name, no date of birth, and no annoying capcha. Just "Create a new account" and you're done.
The app presents you with your public key. This is like an address that can be used to find your posts on Nostr. It is 100% unique to you, and no one else can post a note that lists this npub as the author, because they won't have the corresponding private key. You don't need to remember your npub, though. You'll be able to readily copy it from any Nostr app you use whenever you need it.
You will also be prompted to add a nickname. This is just for use within Amber, since you can set up multiple profiles within the app. You can use anything you want here, as it is just so you can tell which profile is which when switching between them in Amber.
Once you've set your nickname, tap on "Continue."
The next screen will ask you what Amber's default signing policy should be.
The default is to approve basic actions, referring to things that are common for Nostr clients to request a signature for, like following another user, liking a post, making a new post, or replying. If you are more concerned about what Amber might be signing for on your behalf, you can tell it to require manual approval for each app.
Once you've made your decision, tap "Finish." You will also be able to change this selection in the app settings at any time.
With this setup out of the way, you are now presented with the main "Applications" page of the app.
At the top, you have a notification encouraging you to create a backup. Let's get that taken care of now by tapping on the notification and skipping down to the heading titled "Backing Up Your Identity" in this tutorial.
Existing Nostrich
Upon opening the application, you will be presented with the option to use your private key or create a new Nostr account. Choose the former.
The next screen will require you to paste your private key.
You will need to obtain this from whatever Nostr app you used to create your profile, or any other Nostr app that you pasted your nsec into in the past. Typically you can find it in the app settings and there will be a section mentioning your keys where you can copy your nsec. For instance, in Primal go to Settings > Keys > Copy private key, and on Amethyst open the side panel by tapping on your profile picture in the top-left, then Backup Keys > Copy my secret key.
After pasting your nsec into Amber, tap "Next."
Amber will give you a couple options for a default signing policy. The default is to approve basic actions, referring to things that are common for Nostr clients to request a signature for, like following another user, liking a post, making a new post, or replying. If you are more concerned about what Amber might be signing for on your behalf, you can tell it to require manual approval for each app.
Once you've made your decision, tap "Finish." You will also be able to change this selection in the app settings at any time.
With this setup out of the way, you are now presented with the main "Applications" page of the app. You have nothing here yet, since you haven't used Amber to log into any Nostr apps, but this will be where all of the apps you have connected with Amber will be listed, in the order of the most recently used at the top.
Before we go and use Amber to log into an app, though, let's make sure we've created a backup of our private key. You pasted your nsec into Amber, so you could just save that somewhere safe, but Amber gives you a few other options as well. To find them, you'll need to tap the cog icon at the bottom of the screen to access the settings, then select "Backup Keys."
Backing Up Your Identity
You'll notice that Amber has a few different options for backing up your private key that it can generate.
First, it can give you seed words, just like a Bitcoin seed. If you choose that option, you'll be presented with 12 words you can record somewhere safe. To recover your Nostr private key, you just have to type those words into a compatible application, such as Amber.
The next option is to just copy the secret/private key in its standard form as an "nsec." This is the least secure way to store it, but is also the most convenient, since it is simple to paste into another signer application. If you want to be able to log in on a desktop web app, the browser extension Nostr signers won't necessarily support entering your 12 word seed phrase, but they absolutely will support pasting in your nsec.
You can also display a QR code of your private key. This can be scanned by Amber signer on another device for easily transferring your private key to other devices you want to use it on. Say you have an Android tablet in addition to your phone, for instance. Just make sure you only use this function where you can be certain that no one will be able to get a photograph of that QR code. Once someone else has your nsec, there is no way to recover it. You have to start all over on Nostr. Not a big deal at this point in your journey if you just created a Nostr account, but if you have been using Nostr for a while and have built up a decent amount of reputation, it could be much more costly to start over again.
The next options are a bit more secure, because they require a password that will be used to encrypt your private key. This has some distinct advantages, and a couple disadvantages to be aware of. Using a password to encrypt your private key will give you what is called an ncryptsec, and if this is leaked somehow, whoever has it will not necessarily have access to post as you on Nostr, the way they would if your nsec had been leaked. At least, not so long as they don't also have your password. This means you can store your ncryptsec in multiple locations without much fear that it will be compromised, so long as the password you used to encrypt it was a strong and unique one, and it isn't stored in the same location. Some Nostr apps support an ncryptsec for login directly, meaning that you have the option to paste in your ncryptsec and then just log in with the password you used to encrypt it from there on out. However, now you will need to keep track of both your ncryptsec and your password, storing both of them safely and separately. Additionally, most Nostr clients and signer applications do not support using an ncryptsec, so you will need to convert it back to a standard nsec (or copy the nsec from Amber) to use those apps.
The QR option using an ncryptsec is actually quite useful, though, and I would go this route when trying to set up Amber on additional devices, since anyone possibly getting a picture of the QR code is still not going to be able to do anything with it, unless they also get the password you used to encrypt it.
All of the above options will require you to enter the PIN you set up for your device, or biometric authentication, just as an additional precaution before displaying your private key to you.
As for what "store it in a safe place" looks like, I highly recommend a self-hosted password manager, such as Vaultwarden+Bitwarden or KeePass. If you really want to get wild, you can store it on a hardware signing device, or on a steel seed plate.
Additional Settings
Amber has some additional settings you may want to take advantage of. First off, if you don't want just anyone who has access to your phone to be able to approve signing requests, you can go into the Security settings add a PIN or enable biometrics for signing requests. If you enable the PIN, it will be separate from the PIN you use to access your phone, so you can let someone else use your phone, like your child who is always begging to play a mobile game you have installed, without worrying that they might have access to your Nostr key to post on Amethyst.
Amber also has some relay settings. First are the "Active relays" which are used for signing requests sent to Amber remotely from Nostr web apps. This is what enables you to use Amber on your phone to log into Nostr applications on your desktop web browser, such as Jumble.social, Coracle.social, or Nostrudel.ninja, eliminating your need to use any other application to store your nsec whatsoever. You can leave this relay as the default, or you can add other relays you want to use for signing requests. Just be aware, not all relays will accept the notes that are used for Nostr signing requests, so make sure that the relay you want to use does so. In fact, Amber will make sure of this for you when you type in the relay address.
The next type of relays that you can configure in Amber are the "Default profile relays." These are used for reading your profile information. If you already had a Nostr identity that you imported to Amber, you probably noticed it loaded your profile picture and display name, setting the latter as your nickname in Amber. These relays are where Amber got that information from. The defaults are relay.nostr.band and purplepag.es. The reason for this is because they are aggregators that look for Nostr profiles that have been saved to other relays on the network and pull them in. Therefore, no matter what other relay you may save your profile to, Amber will likely be able to find it on one of those two relays as well. If you have a relay you know you will be saving your Nostr profiles to, you may want to add it to this list.
You can also set up Amber to be paired with Orbot for signing over Tor using relays that are only accessible via the Tor network. That is an advanced feature, though, and well beyond the scope of this tutorial.
Finally, you can update the default signing policy. Maybe after using Amber for a while, you've decided that the choice you made before was too strict or too lenient. You can change it to suit your needs.
Zapstore Login
Now that you are all set up with Amber, let's get you signed into your first Nostr app by going back to the Zapstore.
From the app's home screen, tap on the user icon in the upper left of the screen. This will open a side panel with not much on it except the option to "sign in." Go ahead and tap on it.
You will be presented with the option to either sign in with Amber, or to paste your npub. However, if you do the latter, you will only have read access, meaning you cannot zap any of the app releases. There are other features planned for the Zapstore that may also require you to be signed in with write access, so go ahead and choose to log in with Amber.
Your phone should automatically switch to Amber to approve the sign-in request.
You can choose to only approve basic actions for Zapstore, require it to manually approve every time, or you can tell it that you "fully trust this application." Only choose the latter option with apps you have used for a while and they have never asked you to sign for anything suspicious. For the time being, I suggest you use the "Approve basic actions" option and tap "Grant Permissions."
Your phone will switch back to the Zapstore and will show that you are now signed in. Congratulations! From here on out, logging into most Nostr applications will be as easy as tapping on "Log in with Amber" and approving the request.
If you set up a new profile, it will just show a truncated version of your npub rather than the nickname you set up earlier. That's fine. You'll have an opportunity to update your Nostr profile in the next tutorial in this series and ensure that it is spread far and wide in the network, so the Zapstore will easily find it.
That concludes the tutorial for Amber. While we have not covered using Amber to log into Nostr web apps, that is outside the scope of this series, and I will cover it in an upcoming tutorial regarding using Amber's remote signer options in detail.
Since you're already hanging out in the Zapstore, you may as well stick around, because we will be using it right out the gate in the next part of this series: Amethyst Installation and Setup. (Coming Soon)

Bitzeny 390 ZNY Bitcoin 3,900 sats (Lightning Network)
Ethereum 0.0039 ETH (zkSync) “39” sounds like “thank you” in Japanese. Prices aren’t pegged to yen.These days I’m open only once a week. On other days I’m out scouting new spots for the kitchen-car. If you know weekday-lunch locations inside Tokyo where I could set up, please let me know!
The photo shows an NFC tag. If your phone has a Lightning wallet, just tap and pay 3,900 sats. I admit this hand-written NFC tag looks shady—any self-respecting Bitcoiner probably wouldn’t want to tap it—but the point is: even this works!
I used to run a BTCPay POS, but I switched to this setup for speed. Sometimes the tap payment fails; if that happens I reluctantly pull out the old POS. Thanks for your patience.
It’s been one year since I spun up a node and started accepting Lightning payments. So many people are now running their own nodes—Umbrel really is amazing. While the big players bravely chase routing fees, I’m a tiny operator scraping together funds while begging my wife for forgiveness, so I’m all-in on maximising payment convenience. Your support means a lot!
If I may add: routing is fun, but instant, trust-minimised payments and the thrill of choosing whom to open channels with are just as exciting. You’ll only understand once you start accepting payments yourself—zero-confirmation settlement really is revolutionary.
QR codes, NFC taps, fixed amounts, manual entry… the possibilities keep multiplying, and the pace of innovation is scary fast. When I compare it to the merchant fees on Japan’s most-used service, PayPay, I want to shout: “Bitcoin is incredible!” Sure, taxes, price volatility (my shop is BTC-denominated, though), wallet UX, and adoption hurdles are still pain points.
Even so, lots of people keep building cool stuff, so I’ll keep doing what I can—still on my knees to my wife, but moving forward!

2025-04-29 13:38:49The vag' sits on the edge of the highway, broken, hungry. Overhead flies a transcontinental plane filled with highly paid executives. The upper class has taken to the air, the lower class to the roads: there is no longer any bond between them, they are two nations."—The Sovereign Individual
Fire
I was talking to a friend last night. Coffee in hand. Watching flames consume branches. Spring night on his porch.
He believed in America's happy ending. Debt would vanish. Inflation would cool. Manufacturing would return. Good guys win.
I nodded. I wanted to believe.
He leaned forward, toward the flame. I sat back, watching both fire and sky.
His military photos hung inside. Service medals displayed. Patriotism bone-deep.
The pendulum clock on his porch wall swung steadily. Tick. Tock. Measuring moments. Marking epochs.
History tells another story. Not tragic. Just true.
Our time has come. America cut off couldn't compete. Factories sit empty. Supply chains span oceans. Skills lack. Children lag behind. Rebuilding takes decades.
Truth hurts. Truth frees.
Cycles
History moves in waves. Every 500 years, power shifts. Systems fall. Systems rise.
500 BC - Greek coins changed everything. Markets flourished. Athens dominated.
1 AD - Rome ruled commerce. One currency. Endless roads. Bustling ports.
500 AD - Rome faded. Not overnight. Slowly. Trade withered. Cities emptied. Money debased. Roads crumbled. Local strongmen rose. Peasants sought protection. Feudalism emerged.
People still lived. Still worked. Horizons narrowed. Knowledge concentrated. Most barely survived. Rich adapted. Poor suffered.
Self-reliance determined survival. Those growing food endured. Those making essential goods continued. Those dependent on imperial systems suffered most.
1000 AD - Medieval revival began. Venice dominated seas. China printed money. Cathedrals rose. Universities formed.
1500 AD - Europeans sailed everywhere. Spanish silver flowed. Banks financed kingdoms. Companies colonized continents. Power moved west.
The pendulum swung. East to West. West to East. Civilizations rose. Civilizations fell.
2000 AD - Pattern repeats. America strains. Digital networks expand. China rises. Debt swells. Old systems break.
We stand at the hinge.
Warnings
Signs everywhere. Dollar weakens globally. BRICS builds alternatives. Yuan buys oil. Factories rust. Debt exceeds GDP. Interest consumes budgets.
Bridges crumble. Education falters. Politicians chase votes. We consume. We borrow.
Rome fell gradually. Citizens barely noticed. Taxes increased. Currency devalued. Military weakened. Services decayed. Life hardened by degrees.
East Rome adapted. Survived centuries. West fragmented. Trade shrank. Some thrived. Others suffered. Life changed permanently.
Those who could feed themselves survived best. Those who needed the system suffered worst.
Pendulum
My friend poured another coffee. The burn pile popped loudly. Sparks flew upward like dying stars.
His face changed as facts accumulated. Military man. Trained to assess threats. Detect weaknesses.
He stared at the fire. National glory reduced to embers. Something shifted in his expression. Recognition.
His fingers tightened around his mug. Knuckles white. Eyes fixed on dying flames.
I traced the horizon instead. Observing landscape. Noting the contrast.
He touched the flag on his t-shirt. I adjusted my plain gray one.
The unpayable debt. The crumbling infrastructure. The forgotten manufacturing. The dependent supply chains. The devaluing currency.
The pendulum clock ticked. Relentless. Indifferent to empires.
His eyes said what his patriotism couldn't voice. Something fundamental breaking.
I'd seen this coming. Years traveling showed me. Different systems. Different values. American exceptionalism viewed from outside.
Pragmatism replaced my old idealism. See things as they are. Not as wished.
The logs shifted. Flames reached higher. Then lower. The cycle of fire.
Divergence
Society always splits during shifts.
Some adapt. Some don't.
Printing arrived. Scribes starved. Publishers thrived. Information accelerated. Readers multiplied. Ideas spread. Adapters prospered.
Steam engines came. Weavers died. Factory owners flourished. Villages emptied. Cities grew. Coal replaced farms. Railways replaced wagons. New skills meant survival.
Computers transformed everything. Typewriters vanished. Software boomed. Data replaced paper. Networks replaced cabinets. Programmers replaced typists. Digital skills determined success.
The self-reliant thrived in each transition. Those waiting for rescue fell behind.
Now AI reshapes creativity. Some artists resist. Some harness it. Gap widens daily.
Bitcoin offers refuge. Critics mock. Adopters build wealth. The distance grows.
Remote work redraws maps. Office-bound struggle. Location-free flourish.
The pendulum swings. Power shifts. Some rise with it. Some fall against it.
Two societies emerge. Adaptive. Resistant. Prepared. Pretending.
Advantage
Early adapters win. Not through genius. Through action.
First printers built empires. First factories created dynasties. First websites became giants.
Bitcoin followed this pattern. Laptop miners became millionaires. Early buyers became legends.
Critics repeat themselves: "Too volatile." "No value." "Government ban coming."
Doubters doubt. Builders build. Gap widens.
Self-reliance accelerates adaptation. No permission needed. No consensus required. Act. Learn. Build.
The burn pile flames like empire's glory. Bright. Consuming. Temporary.
Blindness
Our brains see tigers. Not economic shifts.
We panic at headlines. We ignore decades-long trends.
We notice market drops. We miss debt cycles.
We debate tweets. We ignore revolutions.
Not weakness. Just humanity. Foresight requires work. Study. Thought.
Self-reliant thinking means seeing clearly. No comforting lies. No pleasing narratives. Just reality.
The clock pendulum swings. Time passes regardless of observation.
Action
Empires fall. Families need security. Children need futures. Lives need meaning.
You can adapt faster than nations.
Assess honestly. What skills matter now? What preserves wealth? Who helps when needed?
Never stop learning. Factory workers learned code. Taxi drivers joined apps. Photographers went digital.
Diversify globally. No country owns tomorrow. Learn languages. Make connections. Stay mobile.
Protect your money. Dying empires debase currencies. Romans kept gold. Bitcoin offers similar shelter.
Build resilience. Grow food. Make energy. Stay strong. Keep friends. Read old books. Some things never change.
Self-reliance matters most. Can you feed yourself? Can you fix things? Can you solve problems? Can you create value without systems?
Movement
Humans were nomads first. Settlers second. Movement in our blood.
Our ancestors followed herds. Sought better lands. Survival meant mobility.
The pendulum swings here too. Nomad to farmer. City-dweller to digital nomad.
Rome fixed people to land. Feudalism bound serfs to soil. Nations created borders. Companies demanded presence.
Now technology breaks chains. Work happens anywhere. Knowledge flows everywhere.
The rebuild America seeks requires fixed positions. Factory workers. Taxpaying citizens in permanent homes.
But technology enables escape. Remote work. Digital currencies. Borderless businesses.
The self-reliant understand mobility as freedom. One location means one set of rules. One economy. One fate.
Many locations mean options. Taxes become predatory? Leave. Opportunities disappear? Find new ones.
Patriotism celebrates roots. Wisdom remembers wings.
My friend's boots dug into his soil. Planted. Territorial. Defending.
My Chucks rested lightly. Ready. Adaptable. Departing.
His toolshed held equipment to maintain boundaries. Fences. Hedges. Property lines.
My backpack contained tools for crossing them. Chargers. Adapters. Currency.
The burn pile flame flickers. Fixed in place. The spark flies free. Movement its nature.
During Rome's decline, the mobile survived best. Merchants crossing borders. Scholars seeking patrons. Those tied to crumbling systems suffered most.
Location independence means personal resilience. Economic downturns become geographic choices. Political oppression becomes optional suffering.
Technology shrinks distance. Digital work. Video relationships. Online learning.
Self-sovereignty requires mobility. The option to walk away. The freedom to arrive elsewhere.
Two more worlds diverge. The rooted. The mobile. The fixed. The fluid. The loyal. The free.
Hope
Not decline. Transition. Painful but temporary.
America may weaken. Humanity advances. Technology multiplies possibilities. Poverty falls. Knowledge grows.
Falling empires see doom. Rising ones see opportunity. Both miss half the picture.
Every shift brings destruction and creation. Rome fell. Europe struggled. Farms produced less. Cities shrank. Trade broke down.
Yet innovation continued. Water mills appeared. New plows emerged. Monks preserved books. New systems evolved.
Different doesn't mean worse for everyone.
Some industries die. Others birth. Some regions fade. Others bloom. Some skills become useless. Others become gold.
The self-reliant thrive in any world. They adapt. They build. They serve. They create.
Choose your role. Nostalgia or building.
The pendulum swings. East rises again. The cycle continues.
Fading
The burn pile dimmed. Embers fading. Night air cooling.
My friend's shoulders changed. Tension releasing. Something accepted.
His patriotism remained. His illusions departed.
The pendulum clock ticked steadily. Measuring more than minutes. Measuring eras.
Two coffee cups. His: military-themed, old and chipped but cherished. Mine: plain porcelain, new and unmarked.
His eyes remained on smoldering embers. Mine moved between him and the darkening trees.
His calendar marked local town meetings. Mine tracked travel dates.
The last flame flickered out. Spring peepers filled the silence.
In darkness, we watched smoke rise. The world changing. New choices ahead.
No empire lasts forever. No comfort in denial. Only clarity in acceptance.
Self-reliance the ancient answer. Build your skills. Secure your resources. Strengthen your body. Feed your mind. Help your neighbors.
The burn pile turned to ash. Empire's glory extinguished.
He stood facing his land. I faced the road.
A nod between us. Respect across division. Different strategies for the same storm.
He turned toward his home. I toward my vehicle.
The pendulum continued swinging. Power flowing east once more. Five centuries ending. Five centuries beginning.

Tomorrow depends not on nations. On us.

2025-05-29 10:01:20Jacopo Graziuso’s econometric study explains how the presence of Bitcoin is connected to the reduction of emissions and consumption in countries where it is mined.
The debate on Bitcoin’s environmental impact has been at the center of media attention for years, often characterized by approximate information and common misconceptions. But what emerges when data is analyzed? An answer comes from the study by Jacopo Graziuso, a recent graduate in Economics and Finance at the University of Salento, who dedicated his thesis to the topic, titled: “Bitcoin and energy: towards efficiency and environmental sustainability”.
“It bothers me when they tell me ‘Bitcoin pollutes, Bitcoin consumes’. This prompted me to write the thesis,” Graziuso tells Atlas21 microphones. “We live in an era of free and accessible information, yet disinformation reigns supreme, leading to beliefs without scientific foundation.”
Regarding his research work, Graziuso emphasizes: “I thank professor of econometrics Pierluigi Toma who knew what Bitcoin is and what mining is and gave me carte blanche for writing the thesis.”
The methodology used for the study is an econometric analysis based on data from 171 states from 2009 to 2024, with particular attention to the relationship between Bitcoin presence, greenhouse gas emissions (climate-altering gases) and energy consumption. To define Bitcoin’s “presence”, Graziuso created a variable that takes value 1 if at least 1% of the population uses (knows or has a wallet) the cryptocurrency or if it is present in state reserves.
The results of the research, conducted only with open source software, contradict the dominant narrative, Graziuso explains: “The analysis shows that Bitcoin’s presence in a state is associated with a decrease in greenhouse gas emissions. The study reveals that Bitcoin’s presence in a state reduces emissions by 39 megatons of CO2 equivalent. Essentially, where there is Bitcoin, climate-altering gas emissions decrease.”
Graziuso wants to emphasize the difference between consumption and pollution: “The problem is not consumption, it’s pollution. The distinction is fundamental: energy consumption is necessary for human development, while pollution derives from the use of inefficient energy sources. Currently China consumes over 4500% more than the entire Bitcoin network. Furthermore, thanks to mining flexibility, Bitcoin can help a state reduce general consumption.”
The research highlights how mining is acting as a catalyst for the adoption of renewable and nuclear energy. Mining naturally seeks the cheapest sources which increasingly coincide with the cleanest ones, the interviewee states.
One analyzed aspect is Bitcoin’s role as “buyer of last resort” for otherwise wasted energy. Graziuso cites several examples:
- Alps Blockchain, which has reactivated 32 disused hydroelectric plants in northern Italy and is working on building facilities in Paraguay and Ecuador exploiting hydroelectric energy;
- projects like Gridless that exploit excess energy from renewable sources in remote areas: “Not only does [Gridless] optimize the use of local energy resources, but it reinvests mining profits in communities, improving access to electricity and supporting the local economy,” writes Graziuso;
- in Texas, thanks to agreements with electricity grid operator ERCOT, miners exploit the operational flexibility of their machines to adapt consumption to grid needs, turning them off during peak moments and turning them back on when there is surplus energy, thus acting as buyers of last resort and contributing to stabilizing the electrical grid.
Another interesting aspect concerns the recovery of heat generated by machines: “Marathon Digital Holdings in Finland uses heat from its ASICs to heat 80,000 homes,” explains Graziuso. “Domestic applications are also being developed where ASIC heat is used for heating, further mitigating pollution.”
Immersion cooling, a technique that involves immersing mining machines in a dielectric fluid made in the laboratory, is cited as a promising solution to improve efficiency and reduce environmental impact. This way it is also possible to reduce machine noise, while the heat produced is dissipated by the dielectric material. Graziuso cites CleanSpark as an example of a completely carbon neutral mining farm that uses this technology: “This cooling technique allows us to safely overclock hardware, increasing performance by increasing operating frequency beyond factory settings,” states CleanSpark.
The thesis includes a section dedicated to zones that are emerging as sustainable mining hubs in different parts of the world:
- in Kenya and Ethiopia, “mining powered by hydroelectric energy is bringing drinking water and electricity to previously unserved communities,” declares Graziuso;
- in Georgia and Texas, Bitcoin mining is contributing to making the electrical grid more stable, intervening during peak demand moments and absorbing excess energy during overproduction periods;
- in Canada, companies like Upstream Data and Hut 8 Mining use mining to valorize excess or dispersed energy, including gas flaring in oil fields, thus reducing energy waste and emissions;
- the Makai project in Hawaii exploits OTEC (Ocean Thermal Energy Conversion) technology to convert ocean thermal energy into clean and renewable electricity.
Despite mining’s potential, obstacles to complete decarbonization still exist: “Decarbonization is still far away. Currently in many countries there are still state incentives from 40 years ago that favor fossil sources. Due to these incentives, today entrepreneurs’ costs are lower when fossil fuels are used. Once these state incentives end, perhaps the situation will improve. At the moment it is the miners who must voluntarily use renewable sources,” observes Graziuso. Italy, for example, continues to depend about 60% on fossil sources.
Another piece of data analyzed in the thesis is the improvement in energy efficiency of specialized mining machines: “In about 15 years, efficiency has improved by over 95%: this means decreased consumption and pollution,” emphasizes Graziuso.
“I hope this research contributes to spreading a more accurate and data-based narrative,” concludes Graziuso. “Bitcoin is not the problem, but could be part of the solution to the global energy challenge.”
The thesis will soon be published in its entirety online as a scientific paper.
The post Bitcoin reduces emissions and consumption: the thesis published at the University of Salento appeared first on Atlas21.

2025-05-27 16:19:06Star Wars is often viewed as a myth of rebellion, freedom, and resistance to tyranny. The iconography—scrappy rebels, totalitarian stormtroopers, lone smugglers—suggests a deep anti-authoritarian ethos. Yet, beneath the surface, the narrative arc of Star Wars consistently affirms the necessity, even sanctity, of central authority. This blog entry introduces the question: Is Star Wars fundamentally a celebration of statism?
Rebellion as Restoration, Not Revolution
The Rebel Alliance’s mission is not to dismantle centralized power, but to restore the Galactic Republic—a bureaucratic, centrally governed institution. Characters like Mon Mothma and Bail Organa are high-ranking senators, not populist revolutionaries. The goal is to remove the corrupt Empire and reinstall a previous central authority, presumed to be just.
- Rebels are loyalists to a prior state structure.
- Power is not questioned, only who wields it.
Jedi as Centralized Moral Elites
The Jedi, often idealized as protectors of peace, are unelected, extra-legal enforcers of moral and military order. Their authority stems from esoteric metaphysical abilities rather than democratic legitimacy.
- They answer only to their internal Council.
- They are deployed by the Senate, but act independently of civil law.
- Their collapse is depicted as tragic not because they were unaccountable, but because they were betrayed.
This positions them as a theocratic elite, not spiritual anarchists.
Chaos and the Frontier: The Case of the Cantina
The Mos Eisley cantina, often viewed as a symbol of frontier freedom, reveals something darker. It is: - Lawless - Violent - Culturally fragmented
Conflict resolution occurs through murder, not mediation. Obi-Wan slices off a limb; Han shoots first—both without legal consequence. There is no evidence of property rights, dispute resolution, or voluntary order.
This is not libertarian pluralism—it’s moral entropy. The message: without centralized governance, barbarism reigns.
The Mythic Arc: Restoration of the Just State
Every trilogy in the saga returns to a single theme: the fall and redemption of legitimate authority.
- Prequels: Republic collapses into tyranny.
- Originals: Rebels fight to restore legitimate order.
- Sequels: Weak governance leads to resurgence of authoritarianism; heroes must reestablish moral centralism.
The story is not anti-state—it’s anti-bad state. The solution is never decentralization; it’s the return of the right ruler or order.
Conclusion: The Hidden Statism of a Rebel Myth
Star Wars wears the costume of rebellion, but tells the story of centralized salvation. It: - Validates elite moral authority (Jedi) - Romanticizes restoration of fallen governments (Republic) - Portrays decentralized zones as corrupt and savage (outer rim worlds)
It is not an anarchist parable, nor a libertarian fable. It is a statist mythology, clothed in the spectacle of rebellion. Its core message is not that power should be abolished, but that power belongs to the virtuous few.
Question to Consider:
If the Star Wars universe consistently affirms the need for centralized moral and political authority, should we continue to see it as a myth of freedom? Or is it time to recognize it as a narrative of benevolent empire? -

In a sun-dappled jungle, Zippy the gecko darted across a broad leaf, his emerald scales glinting. Chasing a juicy cricket, he leaped, only to slip into a pitcher plant’s slippery trap. With sticky toes, Zippy clung to the edge, heart racing. A curious frog peered in, offering a vine. Grateful, Zippy climbed out, sharing his cricket with his new friend. Under the moon’s glow, they danced on the leaves, tales of their adventure echoing through the jungle night.

2025-05-29 09:01:38The company is facing a class action lawsuit following a stock price drop triggered by the delayed disclosure of a December data breach.
Coinbase finds itself at the center of a legal storm after being hit with a class action lawsuit filed by shareholders. The lawsuit stems from a decline in the company’s stock price, which occurred after the belated communication of a cybersecurity incident.
The class action, filed in the United States District Court for the Eastern District of Pennsylvania, names investor Brady Nessler as the lead plaintiff. The suit claims that the platform’s shareholders suffered “substantial losses and damages” due to the company’s alleged failure to disclose material information.
Investors accuse the company of not promptly revealing crucial details that could have influenced investment decisions. Among the main allegations is the failure to immediately communicate a data breach that took place last December.
Details of the breach
On May 15, Coinbase publicly disclosed the news of a cyberattack that occurred last December. The incident involved cybercriminals who managed to corrupt several company employees, gaining unauthorized access to customer personal data.
The delayed disclosure of the data breach triggered an immediate stock market reaction. Coinbase shares fell 7.2%, closing the day at $244.
The exchange estimated that the financial impact of the data breach could range between $180 million and $400 million. These costs would cover both expenses to restore security systems and potential reimbursements to customers affected by the incident.
The lawsuit highlights that the company should have communicated these estimated costs to investors more promptly, allowing them to make informed decisions about their investments.
Additional allegations in the lawsuit
In addition to the data breach, the lawsuit lists a series of other alleged communication failures by the company. Among them is the non-disclosure of a violation by CB Payments — Coinbase’s UK subsidiary — of a 2020 agreement with the UK’s Financial Conduct Authority.
The class action covers all investors who acquired company shares between April 14, 2021, and May 14, 2025 — a period during which the allegedly omitted information is believed to have negatively affected the stock price.
The legal action doesn’t target the company alone but also names top executives including CEO Brian Armstrong and CFO Alesia Haas among the defendants.

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。 ```
