2025-03-04 17:00:18This piece is the first in a series that will focus on things I think are a priority if your focus is similar to mine: building a strong family and safeguarding their future.
Choosing the ideal place to raise a family is one of the most significant decisions you will ever make. For simplicity sake I will break down my thought process into key factors: strong property rights, the ability to grow your own food, access to fresh water, the freedom to own and train with guns, and a dependable community.
A Jurisdiction with Strong Property Rights
Strong property rights are essential and allow you to build on a solid foundation that is less likely to break underneath you. Regions with a history of limited government and clear legal protections for landowners are ideal. Personally I think the US is the single best option globally, but within the US there is a wide difference between which state you choose. Choose carefully and thoughtfully, think long term. Obviously if you are not American this is not a realistic option for you, there are other solid options available especially if your family has mobility. I understand many do not have this capability to easily move, consider that your first priority, making movement and jurisdiction choice possible in the first place.
Abundant Access to Fresh Water
Water is life. I cannot overstate the importance of living somewhere with reliable, clean, and abundant freshwater. Some regions face water scarcity or heavy regulations on usage, so prioritizing a place where water is plentiful and your rights to it are protected is critical. Ideally you should have well access so you are not tied to municipal water supplies. In times of crisis or chaos well water cannot be easily shutoff or disrupted. If you live in an area that is drought prone, you are one drought away from societal chaos. Not enough people appreciate this simple fact.
Grow Your Own Food
A location with fertile soil, a favorable climate, and enough space for a small homestead or at the very least a garden is key. In stable times, a small homestead provides good food and important education for your family. In times of chaos your family being able to grow and raise healthy food provides a level of self sufficiency that many others will lack. Look for areas with minimal restrictions, good weather, and a culture that supports local farming.
Guns
The ability to defend your family is fundamental. A location where you can legally and easily own guns is a must. Look for places with a strong gun culture and a political history of protecting those rights. Owning one or two guns is not enough and without proper training they will be a liability rather than a benefit. Get comfortable and proficient. Never stop improving your skills. If the time comes that you must use a gun to defend your family, the skills must be instinct. Practice. Practice. Practice.
A Strong Community You Can Depend On
No one thrives alone. A ride or die community that rallies together in tough times is invaluable. Seek out a place where people know their neighbors, share similar values, and are quick to lend a hand. Lead by example and become a good neighbor, people will naturally respond in kind. Small towns are ideal, if possible, but living outside of a major city can be a solid balance in terms of work opportunities and family security.
Let me know if you found this helpful. My plan is to break down how I think about these five key subjects in future posts.

2025-02-25 03:55:08Here’s a revised timeline of macro-level events from The Mandibles: A Family, 2029–2047 by Lionel Shriver, reimagined in a world where Bitcoin is adopted as a widely accepted form of money, altering the original narrative’s assumptions about currency collapse and economic control. In Shriver’s original story, the failure of Bitcoin is assumed amid the dominance of the bancor and the dollar’s collapse. Here, Bitcoin’s success reshapes the economic and societal trajectory, decentralizing power and challenging state-driven outcomes.
Part One: 2029–2032
-
2029 (Early Year)\ The United States faces economic strain as the dollar weakens against global shifts. However, Bitcoin, having gained traction emerges as a viable alternative. Unlike the original timeline, the bancor—a supranational currency backed by a coalition of nations—struggles to gain footing as Bitcoin’s decentralized adoption grows among individuals and businesses worldwide, undermining both the dollar and the bancor.
-
2029 (Mid-Year: The Great Renunciation)\ Treasury bonds lose value, and the government bans Bitcoin, labeling it a threat to sovereignty (mirroring the original bancor ban). However, a Bitcoin ban proves unenforceable—its decentralized nature thwarts confiscation efforts, unlike gold in the original story. Hyperinflation hits the dollar as the U.S. prints money, but Bitcoin’s fixed supply shields adopters from currency devaluation, creating a dual-economy split: dollar users suffer, while Bitcoin users thrive.
-
2029 (Late Year)\ Dollar-based inflation soars, emptying stores of goods priced in fiat currency. Meanwhile, Bitcoin transactions flourish in underground and online markets, stabilizing trade for those plugged into the bitcoin ecosystem. Traditional supply chains falter, but peer-to-peer Bitcoin networks enable local and international exchange, reducing scarcity for early adopters. The government’s gold confiscation fails to bolster the dollar, as Bitcoin’s rise renders gold less relevant.
-
2030–2031\ Crime spikes in dollar-dependent urban areas, but Bitcoin-friendly regions see less chaos, as digital wallets and smart contracts facilitate secure trade. The U.S. government doubles down on surveillance to crack down on bitcoin use. A cultural divide deepens: centralized authority weakens in Bitcoin-adopting communities, while dollar zones descend into lawlessness.
-
2032\ By this point, Bitcoin is de facto legal tender in parts of the U.S. and globally, especially in tech-savvy or libertarian-leaning regions. The federal government’s grip slips as tax collection in dollars plummets—Bitcoin’s traceability is low, and citizens evade fiat-based levies. Rural and urban Bitcoin hubs emerge, while the dollar economy remains fractured.
Time Jump: 2032–2047
- Over 15 years, Bitcoin solidifies as a global reserve currency, eroding centralized control. The U.S. government adapts, grudgingly integrating bitcoin into policy, though regional autonomy grows as Bitcoin empowers local economies.
Part Two: 2047
-
2047 (Early Year)\ The U.S. is a hybrid state: Bitcoin is legal tender alongside a diminished dollar. Taxes are lower, collected in BTC, reducing federal overreach. Bitcoin’s adoption has decentralized power nationwide. The bancor has faded, unable to compete with Bitcoin’s grassroots momentum.
-
2047 (Mid-Year)\ Travel and trade flow freely in Bitcoin zones, with no restrictive checkpoints. The dollar economy lingers in poorer areas, marked by decay, but Bitcoin’s dominance lifts overall prosperity, as its deflationary nature incentivizes saving and investment over consumption. Global supply chains rebound, powered by bitcoin enabled efficiency.
-
2047 (Late Year)\ The U.S. is a patchwork of semi-autonomous zones, united by Bitcoin’s universal acceptance rather than federal control. Resource scarcity persists due to past disruptions, but economic stability is higher than in Shriver’s original dystopia—Bitcoin’s success prevents the authoritarian slide, fostering a freer, if imperfect, society.
Key Differences
- Currency Dynamics: Bitcoin’s triumph prevents the bancor’s dominance and mitigates hyperinflation’s worst effects, offering a lifeline outside state control.
- Government Power: Centralized authority weakens as Bitcoin evades bans and taxation, shifting power to individuals and communities.
- Societal Outcome: Instead of a surveillance state, 2047 sees a decentralized, bitcoin driven world—less oppressive, though still stratified between Bitcoin haves and have-nots.
This reimagining assumes Bitcoin overcomes Shriver’s implied skepticism to become a robust, adopted currency by 2029, fundamentally altering the novel’s bleak trajectory.

2025-02-21 18:15:52"Malcolm Forbes recounts that a lady, wearing a faded cotton dress, and her husband, dressed in an old handmade suit, stepped off a train in Boston, USA, and timidly made their way to the office of the president of Harvard University. They had come from Palo Alto, California, and had not scheduled an appointment. The secretary, at a glance, thought that those two, looking like country bumpkins, had no business at Harvard.
— We want to speak with the president — the man said in a low voice.
— He will be busy all day — the secretary replied curtly.
— We will wait.
The secretary ignored them for hours, hoping the couple would finally give up and leave. But they stayed there, and the secretary, somewhat frustrated, decided to bother the president, although she hated doing that.
— If you speak with them for just a few minutes, maybe they will decide to go away — she said.
The president sighed in irritation but agreed. Someone of his importance did not have time to meet people like that, but he hated faded dresses and tattered suits in his office. With a stern face, he went to the couple.
— We had a son who studied at Harvard for a year — the woman said. — He loved Harvard and was very happy here, but a year ago he died in an accident, and we would like to erect a monument in his honor somewhere on campus.— My lady — said the president rudely —, we cannot erect a statue for every person who studied at Harvard and died; if we did, this place would look like a cemetery.
— Oh, no — the lady quickly replied. — We do not want to erect a statue. We would like to donate a building to Harvard.
The president looked at the woman's faded dress and her husband's old suit and exclaimed:
— A building! Do you have even the faintest idea of how much a building costs? We have more than seven and a half million dollars' worth of buildings here at Harvard.
The lady was silent for a moment, then said to her husband:
— If that’s all it costs to found a university, why don’t we have our own?
The husband agreed.
The couple, Leland Stanford, stood up and left, leaving the president confused. Traveling back to Palo Alto, California, they established there Stanford University, the second-largest in the world, in honor of their son, a former Harvard student."

2025-03-05 21:18:52Carbon is a "Long-Tail" asset: the residual earnings that come from an asset after it has had its initial market impact.
The Carbon Cascade converts labile into recalcitrant carbon.
During transformation power is generated and lands restored.
Total production of biomass per annum is 100 billion tons of carbon and at $500 to $2,000 per ton of biochar that's $100 trillion of potential carbon trading on the open market. (fanciful to be sure)

2025-02-17 17:12:01President Trump has intensified immigration enforcement, likening it to a wartime effort. Despite pouring resources into the U.S. Immigration and Customs Enforcement (ICE), arrest numbers are declining and falling short of goals. ICE fell from about 800 daily arrests in late January to fewer than 600 in early February.
Critics argue the administration is merely showcasing efforts with ineffectiveness, while Trump seeks billions more in funding to support his deportation agenda. Increased involvement from various federal agencies is intended to assist ICE, but many lack specific immigration training.
Challenges persist, as fewer immigrants are available for quick deportation due to a decline in illegal crossings. Local sheriffs are also pressured by rising demands to accommodate immigrants, which may strain resources further.

2025-03-05 20:17:49A few months ago, an Uber driver alerted me to the presence of his rival. By that point, Waymo had been testing in Austin for over a year. I hid my excitement during the ride but I applied as a beta tester, noting my belonging to the demographics a PM might test for. My application went ignored until, huzzah, Waymo sent me an email yesterday announcing their self-driving cars are available directly through Uber in Austin.
I configured my allegiance to our new overlords swearing in on my screened sandwich of silicon.
Without willing it, and having forgot my new religion, I woke earlier than planned today and hailed a ride. The app spoke to me, "if you wait 3 minutes longer, we'll send you a car without a driver." For five minutes, I watched a car but not a driver move in the direction of me and my screen.
The ride was nice. I didn't have to theatrically rush to a waiting human. There was less social weirdness than I would normally sit with on a ride. I could inspect the car without risking the driver sense that I'm inspecting them. The car couldn't look at me buffering, deciphering if I am homeless or merely look it. I got to pick my own music. I got to watch people un-contacted by Waymo watch the car.
But ... it drove a lot more like a robot driving a car than a human driving a car. It pumped the brakes a few times as we passed weirdly parked cars uncertain (apparently) if the car might move into our lane. Once it signaled that we were headed into oncoming traffic as a street widened from one lane to two. Worst of all, it dropped me off near an anomalous stretch of sidewalk where my door opened to a wall, and if I were to climb and get out the other side, I'd arrive in the middle lane of a busy street. Trapped, I pinched myself through the door and, like Laura Croft, navigated the road's edge to a sidewalk.
tbh I'm still excited for my next Waymo ride. I'll just choose a different drop-off address.

2025-02-14 23:24:37intro
The Russian state made me a Bitcoiner. In 1991, it devalued my grandmother's hard-earned savings. She worked tirelessly in the kitchen of a dining car on the Moscow–Warsaw route. Everything she had saved for my sister and me to attend university vanished overnight. This story is similar to what many experienced, including Wences Casares. The pain and injustice of that time became my first lessons about the fragility of systems and the value of genuine, incorruptible assets, forever changing my perception of money and my trust in government promises.
In 2014, I was living in Moscow, running a trading business, and frequently traveling to China. One day, I learned about the Cypriot banking crisis and the possibility of moving money through some strange thing called Bitcoin. At the time, I didn’t give it much thought. Returning to the idea six months later, as a business-oriented geek, I eagerly began studying the topic and soon dove into it seriously.
I spent half a year reading articles on a local online journal, BitNovosti, actively participating in discussions, and eventually joined the editorial team as a translator. That’s how I learned about whitepapers, decentralization, mining, cryptographic keys, and colored coins. About Satoshi Nakamoto, Silk Road, Mt. Gox, and BitcoinTalk. Over time, I befriended the journal’s owner and, leveraging my management experience, later became an editor. I was drawn to the crypto-anarchist stance and commitment to decentralization principles. We wrote about the economic, historical, and social preconditions for Bitcoin’s emergence, and it was during this time that I fully embraced the idea.
It got to the point where I sold my apartment and, during the market's downturn, bought 50 bitcoins, just after the peak price of $1,200 per coin. That marked the beginning of my first crypto winter. As an editor, I organized workflows, managed translators, developed a YouTube channel, and attended conferences in Russia and Ukraine. That’s how I learned about Wences Casares and even wrote a piece about him. I also met Mikhail Chobanyan (Ukrainian exchange Kuna), Alexander Ivanov (Waves project), Konstantin Lomashuk (Lido project), and, of course, Vitalik Buterin. It was a time of complete immersion, 24/7, and boundless hope.
After moving to the United States, I expected the industry to grow rapidly, attended events, but the introduction of BitLicense froze the industry for eight years. By 2017, it became clear that the industry was shifting toward gambling and creating tokens for the sake of tokens. I dismissed this idea as unsustainable. Then came a new crypto spring with the hype around beautiful NFTs – CryptoPunks and apes.
I made another attempt – we worked on a series called Digital Nomad Country Club, aimed at creating a global project. The proceeds from selling images were intended to fund the development of business tools for people worldwide. However, internal disagreements within the team prevented us from completing the project.
With Trump’s arrival in 2025, hope was reignited. I decided that it was time to create a project that society desperately needed. As someone passionate about history, I understood that destroying what exists was not the solution, but leaving everything as it was also felt unacceptable. You can’t destroy the system, as the fiery crypto-anarchist voices claimed.
With an analytical mindset (IQ 130) and a deep understanding of the freest societies, I realized what was missing—not only in Russia or the United States but globally—a Bitcoin-native system for tracking debts and financial interactions. This could return control of money to ordinary people and create horizontal connections parallel to state systems. My goal was to create, if not a Bitcoin killer app, then at least to lay its foundation.
At the inauguration event in New York, I rediscovered the Nostr project. I realized it was not only technologically simple and already quite popular but also perfectly aligned with my vision. For the past month and a half, using insights and experience gained since 2014, I’ve been working full-time on this project.

2025-02-13 06:16:49My favorite line in any Marvel movie ever is in “Captain America.” After Captain America launches seemingly a hopeless assault on Red Skull’s base and is captured, we get this line:
“Arrogance may not be a uniquely American trait, but I must say, you do it better than anyone.”
Yesterday, I came across a comment on the song Devil Went Down to Georgia that had a very similar feel to it:
America has seemingly always been arrogant, in a uniquely American way. Manifest Destiny, for instance. The rest of the world is aware of this arrogance, and mocks Americans for it. A central point in modern US politics is the deriding of racist, nationalist, supremacist Americans.
That’s not what I see. I see American Arrogance as not only a beautiful statement about what it means to be American. I see it as an ode to the greatness of humanity in its purest form.
For most countries, saying “our nation is the greatest” is, in fact, twinged with some level of racism. I still don’t have a problem with it. Every group of people should be allowed to feel pride in their accomplishments. The destruction of the human spirit since the end of World War 2, where greatness has become a sin and weakness a virtue, has crushed the ability of people worldwide to strive for excellence.
But I digress. The fears of racism and nationalism at least have a grain of truth when applied to other nations on the planet. But not to America.
That’s because the definition of America, and the prototype of an American, has nothing to do with race. The definition of Americanism is freedom. The founding of America is based purely on liberty. On the God-given rights of every person to live life the way they see fit.
American Arrogance is not a statement of racial superiority. It’s barely a statement of national superiority (though it absolutely is). To me, when an American comments on the greatness of America, it’s a statement about freedom. Freedom will always unlock the greatness inherent in any group of people. Americans are definitionally better than everyone else, because Americans are freer than everyone else. (Or, at least, that’s how it should be.)
In Devil Went Down to Georgia, Johnny is approached by the devil himself. He is challenged to a ridiculously lopsided bet: a golden fiddle versus his immortal soul. He acknowledges the sin in accepting such a proposal. And yet he says, “God, I know you told me not to do this. But I can’t stand the affront to my honor. I am the greatest. The devil has nothing on me. So God, I’m gonna sin, but I’m also gonna win.”

2025-02-05 17:47:16I got into a friendly discussion on X regarding health insurance. The specific question was how to deal with health insurance companies (presumably unfairly) denying claims? My answer, as usual: get government out of it!
The US healthcare system is essentially the worst of both worlds:
- Unlike full single payer, individuals incur high costs
- Unlike a true free market, regulation causes increases in costs and decreases competition among insurers
I'm firmly on the side of moving towards the free market. (And I say that as someone living under a single payer system now.) Here's what I would do:
- Get rid of tax incentives that make health insurance tied to your employer, giving individuals back proper freedom of choice.
- Reduce regulations significantly.
-
In the short term, some people will still get rejected claims and other obnoxious behavior from insurance companies. We address that in two ways:
- Due to reduced regulations, new insurance companies will be able to enter the market offering more reliable coverage and better rates, and people will flock to them because they have the freedom to make their own choices.
- Sue the asses off of companies that reject claims unfairly. And ideally, as one of the few legitimate roles of government in all this, institute new laws that limit the ability of fine print to allow insurers to escape their responsibilities. (I'm hesitant that the latter will happen due to the incestuous relationship between Congress/regulators and insurers, but I can hope.)
Will this magically fix everything overnight like politicians normally promise? No. But it will allow the market to return to a healthy state. And I don't think it will take long (order of magnitude: 5-10 years) for it to come together, but that's just speculation.
And since there's a high correlation between those who believe government can fix problems by taking more control and demanding that only credentialed experts weigh in on a topic (both points I strongly disagree with BTW): I'm a trained actuary and worked in the insurance industry, and have directly seen how government regulation reduces competition, raises prices, and harms consumers.
And my final point: I don't think any prior art would be a good comparison for deregulation in the US, it's such a different market than any other country in the world for so many reasons that lessons wouldn't really translate. Nonetheless, I asked Grok for some empirical data on this, and at best the results of deregulation could be called "mixed," but likely more accurately "uncertain, confused, and subject to whatever interpretation anyone wants to apply."

1️⃣ Be where the bear roams. Stay in its territory, where it hunts for food. No point setting a trap in your backyard if the bear’s chilling in the forest.
2️⃣ Set a well-hidden trap. Bury it, disguise it, and place the bait right in the center. Bears are omnivores—just like secret police KGB agents. And what’s the tastiest bait for them? Money.
3️⃣ Wait for the bear to take the bait. When it reaches in, the trap will snap shut around its paw. It’ll be alive, but stuck. No escape.
Now, what you do with a trapped bear is another question... 😏

2025-01-25 22:16:54President Trump plans to withdraw 20,000 U.S. troops from Europe and expects European allies to contribute financially to the remaining military presence. Reported by ANSA, Trump aims to deliver this message to European leaders since taking office. A European diplomat noted, “the costs cannot be borne solely by American taxpayers.”
The Pentagon hasn't commented yet. Trump has previously sought lower troop levels in Europe and had ordered cuts during his first term. The U.S. currently maintains around 65,000 troops in Europe, with total forces reaching 100,000 since the Ukraine invasion. Trump's new approach may shift military focus to the Pacific amid growing concerns about China.

2025-03-04 19:27:34I was reminded of this comic this morning. Very relevant to this day.
The losers suddenly fear the government. Or rather the current administration. Those that used to fear the government falsely believe they can wield it to do "good". This is an illusion. Like the Ring of Power it has no master. The only winner is the state. It grows more powerful.

2025-03-06 19:55:59Die Kinder einer Grundschule sollten im Herbst 2024 einen Aufsatz über die amtierende deutsche Außenministerin schreiben. Hier das Ergebnis des 12-jährigen Michaels, wie ihn eine Grundschullehrerin eingesandt haben könnte:
„Die Tante in Berlin hat immer eine schöne Haarfrisur und trägt immer schicke Sachen. Wenn sie mit dem Regierungsflieger unterwegs ist (oft klappt das aber nicht richtig, weiß nicht warum), dann knittern ihre Kleider bestimmt überhaupt nicht. Da hat sie es gut, meine Mama bügelt gar nicht gerne.
Auch hat sie eine Hilfe, die ihr Gesicht immer anmalt und ihr die Haare schön macht. Die bekommt wohl einen Haufen Geld dafür, was aus den Steuern abgezweigt wird, die mein Papa, der sehr fleißig arbeitet, bezahlt.
Die Tante, die mir eher wie ein Mädchen in meinem Alter vorkommt, erinnert mich immer an die Lisa aus der Nachbarklasse, die so frech ist, dass ich und andere ihr manchmal an den Haaren ziehen müssen, damit sie wieder vernünftig wird.
Wenn man ihr sagt, sie ist doof, dann wirft sie den Kopf in den Nacken und zieht beleidigt ab.
Überhaupt benimmt sie sich oft, wie eine beleidigte Leberwurst. Und wenn andere was sagen, was ihr nicht passt, wird sie frech. Ich habe gelernt, dass man möglichst nicht frech sein soll.
Ich bin froh, dass sie keinen roten Knopf hat, auf den sie drücken könnte, nur, um mal zu sehen, was dann passiert.
Alle Elefanten auf der Welt sind böse auf sie, weil sie Porzellan viel besser zerdeppern kann, als sie selber.
Mein Papa sagt, dass zu ihrem Beruf zählt, dass man mit den Leuten redet, bevor man Geld gibt, um auf sie zu schießen, aber das kann sie wohl nicht. Was sie wohl tun müsste, wäre Diplomatie (ich bin ehrlich, dass hab ich von Andreas abgeschrieben, der kennt solche Fremdwörter).
Gut gefallen hat mir ihre Einladung zum Kindergeburtstag im Auswärtigen Amt, wo im vergangenen Sommer alle Türen offen waren. Da wurden auch so lustige Videos gedreht, wo so Leute aus dem Fahrstuhl kommen, die so glitzernde Decken umhatten und tanzten.
Mit ihren oft lustigen Sätzen kitzelt sie wichtige Erwachsene von großen Ländern, ohne sie dabei anfassen zu müssen, das würde ich auch gerne können. Ich wüsste schon, wen ich gerne mal so richtig Auskitzeln wollte.
Ganz oft benutzt sie das Wort „Brutaler Angriffskrieg“ und soweit ich das schon verstehe, sagt sie oft Sachen, die gar keinen Sinn ergeben. Meine Lehrerin sagt immer zu uns, wir sollen lieber den Mund halten, wenn wir nicht genau wissen, was wir sagen wollen. Besser sei es, vor dem Reden das Gehirn einzuschalten. Das sehe ich ein und ich bemühe mich wirklich darum. Ich glaube, sie vergisst das manchmal.
Wenn sie mal nicht weiterweiß, kann sie bestimmt noch den Onkel Klaus vom WEF fragen, bei dem sie Politikerin gelernt hat.
Wenn sie mal nicht mehr so feministisch arbeiten kann oder will, könnte sie vielleicht Kindergärtnerin werden, aber ich glaube, kein Kind könnte sie leiden, weil sie immer so altklug und bockig tut, und das können wir Kinder gar nicht leiden. Und eigentlich soll man ja nicht von einem Beruf, den man nicht kann, in einen anderen Beruf wechseln, den man auch nicht kann.
Schön finde ich, dass die ganze Welt über sie lacht, wo doch alles im Moment so traurig ist und alle von Krieg reden und Bedrohung und dass Deutschland wieder kriegstüchtig werden soll. Das macht mir Angst. Da habe ich oft das Gefühl, alle Erwachsenen sind verrückt geworden und benehmen sich nur noch so, wie ich, als ich 8 Jahre alt war. Ich weiß noch, da habe ich ziemlich viel Blödsinn gemacht, aber jetzt bin ich schon viel vernünftiger geworden.
Mein Pausenbrot würde ich nicht mit ihr tauschen, weil ich sie nicht leiden kann, denn sie benimmt sich oft wie die Lisa, und die ist echt eine richtig doofe Ziege.
Weil ich sie nicht mag, wünsche ich mir, dass sie bald nicht mehr im Fernsehen zu sehen ist. Dann kann sie auch ihre Anziehsachen wieder selber bügeln, wie meine Mama.“
(Manche Wünsche gehen in Erfüllung!)

2025-03-04 18:34:23Spoiler Alert
Please do not read this post if you have not read The Three Body Problem or The Dark Forest by Liu Cixin and ever intend to.
Now that you've been warned...
I just finally finished The Dark Forest, the middle book of the three body trilogy. Boy howdy!!! How cool were those last 50 pages!?
So, there's much to discuss for bitcoiners concerning the parallel between the dark forest and the byzantine generals' dilemma, but, for now, can we just talk about the ultra-brief mention of lasers in that chaotic part after the destruction of Starship Earth?
If I got it right, in that era, the general population possesses en masse handgun style lasers. These lasers are powerful enough for self defense, but individually, not powerful enough to take down a spaceship trying to launch. HOWEVER, and this is the cool part, all together they CAN take down a spaceship because...you know, how lasers work and stuff. They compound their energy together or something like that. Correct me here science nerds.
like this, but with lasers, right?
What an interesting, but basically-just-mentioned-in-passing idea! I feel like the implications of this could have been fleshed out a whole lot more, although I can see how it was just a creative idea he came up with to serve a totally different story.
Anyway, it reminded me of bitcoin...but violent. I've long had an idea in the back of my head for a fantasy story in which the magic system is decentralized, but Cixin Liu came up with a really great sci-fi equivalent here. I wonder if some creative storyteller might want to jump on a similar idea?
...and yeah, I know, a WAY bigger discussion could be had about how the dark forest and the byzantine generals' dilemma are similar and the implication that a bitcoiny response could shed light in the dark forest. I just think this whole laser thing is more of a cool parallel right now.

2025-03-04 09:40:50Die «Eliten» führen bereits groß angelegte Pilotprojekte für eine Zukunft durch, die sie wollen und wir nicht. Das schreibt der OffGuardian in einem Update zum Thema «EU-Brieftasche für die digitale Identität». Das Portal weist darauf hin, dass die Akteure dabei nicht gerade zimperlich vorgehen und auch keinen Hehl aus ihren Absichten machen. Transition News hat mehrfach darüber berichtet, zuletzt hier und hier.
Mit der EU Digital Identity Wallet (EUDI-Brieftasche) sei eine einzige von der Regierung herausgegebene App geplant, die Ihre medizinischen Daten, Beschäftigungsdaten, Reisedaten, Bildungsdaten, Impfdaten, Steuerdaten, Finanzdaten sowie (potenziell) Kopien Ihrer Unterschrift, Fingerabdrücke, Gesichtsscans, Stimmproben und DNA enthält. So fasst der OffGuardian die eindrucksvolle Liste möglicher Einsatzbereiche zusammen.
Auch Dokumente wie der Personalausweis oder der Führerschein können dort in elektronischer Form gespeichert werden. Bis 2026 sind alle EU-Mitgliedstaaten dazu verpflichtet, Ihren Bürgern funktionierende und frei verfügbare digitale «Brieftaschen» bereitzustellen.
Die Menschen würden diese App nutzen, so das Portal, um Zahlungen vorzunehmen, Kredite zu beantragen, ihre Steuern zu zahlen, ihre Rezepte abzuholen, internationale Grenzen zu überschreiten, Unternehmen zu gründen, Arzttermine zu buchen, sich um Stellen zu bewerben und sogar digitale Verträge online zu unterzeichnen.
All diese Daten würden auf ihrem Mobiltelefon gespeichert und mit den Regierungen von neunzehn Ländern (plus der Ukraine) sowie über 140 anderen öffentlichen und privaten Partnern ausgetauscht. Von der Deutschen Bank über das ukrainische Ministerium für digitalen Fortschritt bis hin zu Samsung Europe. Unternehmen und Behörden würden auf diese Daten im Backend zugreifen, um «automatisierte Hintergrundprüfungen» durchzuführen.
Der Bundesverband der Verbraucherzentralen und Verbraucherverbände (VZBV) habe Bedenken geäußert, dass eine solche App «Risiken für den Schutz der Privatsphäre und der Daten» berge, berichtet das Portal. Die einzige Antwort darauf laute: «Richtig, genau dafür ist sie ja da!»
Das alles sei keine Hypothese, betont der OffGuardian. Es sei vielmehr «Potential». Damit ist ein EU-Projekt gemeint, in dessen Rahmen Dutzende öffentliche und private Einrichtungen zusammenarbeiten, «um eine einheitliche Vision der digitalen Identität für die Bürger der europäischen Länder zu definieren». Dies ist nur eines der groß angelegten Pilotprojekte, mit denen Prototypen und Anwendungsfälle für die EUDI-Wallet getestet werden. Es gibt noch mindestens drei weitere.
Den Ball der digitalen ID-Systeme habe die Covid-«Pandemie» über die «Impfpässe» ins Rollen gebracht. Seitdem habe das Thema an Schwung verloren. Je näher wir aber der vollständigen Einführung der EUid kämen, desto mehr Propaganda der Art «Warum wir eine digitale Brieftasche brauchen» könnten wir in den Mainstream-Medien erwarten, prognostiziert der OffGuardian. Vielleicht müssten wir schon nach dem nächsten großen «Grund», dem nächsten «katastrophalen katalytischen Ereignis» Ausschau halten. Vermutlich gebe es bereits Pläne, warum die Menschen plötzlich eine digitale ID-Brieftasche brauchen würden.
Die Entwicklung geht jedenfalls stetig weiter in genau diese Richtung. Beispielsweise hat Jordanien angekündigt, die digitale biometrische ID bei den nächsten Wahlen zur Verifizierung der Wähler einzuführen. Man wolle «den Papierkrieg beenden und sicherstellen, dass die gesamte Kette bis zu den nächsten Parlamentswahlen digitalisiert wird», heißt es. Absehbar ist, dass dabei einige Wahlberechtigte «auf der Strecke bleiben» werden, wie im Fall von Albanien geschehen.
Derweil würden die Briten gerne ihre Privatsphäre gegen Effizienz eintauschen, behauptet Tony Blair. Der Ex-Premier drängte kürzlich erneut auf digitale Identitäten und Gesichtserkennung. Blair ist Gründer einer Denkfabrik für globalen Wandel, Anhänger globalistischer Technokratie und «moderner Infrastruktur».
Abschließend warnt der OffGuardian vor der Illusion, Trump und Musk würden den US-Bürgern «diesen Schlamassel ersparen». Das Department of Government Efficiency werde sich auf die digitale Identität stürzen. Was könne schließlich «effizienter» sein als eine einzige App, die für alles verwendet wird? Der Unterschied bestehe nur darin, dass die US-Version vielleicht eher privat als öffentlich sei – sofern es da überhaupt noch einen wirklichen Unterschied gebe.

2025-01-19 21:48:49The recent shutdown of TikTok in the United States due to a potential government ban serves as a stark reminder how fragile centralized platforms truly are under the surface. While these platforms offer convenience, a more polished user experience, and connectivity, they are ultimately beholden to governments, corporations, and other authorities. This makes them vulnerable to censorship, regulation, and outright bans. In contrast, Nostr represents a shift in how we approach online communication and content sharing. Built on the principles of decentralization and user choice, Nostr cannot be banned, because it is not a platform—it is a protocol.
PROTOCOLS, NOT PLATFORMS.
At the heart of Nostr's philosophy is user choice, a feature that fundamentally sets it apart from legacy platforms. In centralized systems, the user experience is dictated by a single person or governing entity. If the platform decides to filter, censor, or ban specific users or content, individuals are left with little action to rectify the situation. They must either accept the changes or abandon the platform entirely, often at the cost of losing their social connections, their data, and their identity.
What's happening with TikTok could never happen on Nostr. With Nostr, the dynamics are completely different. Because it is a protocol, not a platform, no single entity controls the ecosystem. Instead, the protocol enables a network of applications and relays that users can freely choose from. If a particular application or relay implements policies that a user disagrees with, such as censorship, filtering, or even government enforced banning, they are not trapped or abandoned. They have the freedom to move to another application or relay with minimal effort.
THIS IS POWERFUL.
Take, for example, the case of a relay that decides to censor specific content. On a legacy platform, this would result in frustration and a loss of access for users. On Nostr, however, users can simply connect to a different relay that does not impose such restrictions. Similarly, if an application introduces features or policies that users dislike, they can migrate to a different application that better suits their preferences, all while retaining their identity and social connections.
The same principles apply to government bans and censorship. A government can ban a specific application or even multiple applications, just as it can block one relay or several relays. China has implemented both tactics, yet Chinese users continue to exist and actively participate on Nostr, demonstrating Nostr's ability to resistant censorship.
How? Simply, it turns into a game of whack-a-mole. When one relay is censored, another quickly takes its place. When one application is banned, another emerges. Users can also bypass these obstacles by running their own relays and applications directly from their homes or personal devices, eliminating reliance on larger entities or organizations and ensuring continuous access.
AGAIN, THIS IS POWERUFL.
Nostr's open and decentralized design makes it resistant to the kinds of government intervention that led to TikTok's outages this weekend and potential future ban in the next 90 days. There is no central server to target, no company to regulate, and no single point of failure. (Insert your CEO jokes here). As long as there are individuals running relays and applications, users continue creating notes and sending zaps.
Platforms like TikTok can be silenced with the stroke of a pen, leaving millions of users disconnected and abandoned. Social communication should not be silenced so incredibly easily. No one should have that much power over social interactions.
Will we on-board a massive wave of TikTokers in the coming hours or days? I don't know.
TikTokers may not be ready for Nostr yet, and honestly, Nostr may not be ready for them either. The ecosystem still lacks the completely polished applications, tools, and services they’re accustomed to. This is where we say "we're still early". They may not be early adopters like the current Nostr user base. Until we bridge that gap, they’ll likely move to the next centralized platform, only to face another government ban or round of censorship in the future. But eventually, there will come a tipping point, a moment when they’ve had enough. When that time comes, I hope we’re prepared. If we’re not, we risk missing a tremendous opportunity to onboard people who genuinely need Nostr’s freedom.
Until then, to all of the Nostr developers out there, keep up the great work and keep building. Your hard work and determination is needed.

2025-03-01 10:39:35Ständige Lügen und Unterstellungen, permanent falsche Fürsorge \ können Bausteine von emotionaler Manipulation sein. Mit dem Zweck, \ Macht und Kontrolle über eine andere Person auszuüben. \ Apotheken Umschau
Irgendetwas muss passiert sein: «Gaslighting» ist gerade Thema in vielen Medien. Heute bin ich nach längerer Zeit mal wieder über dieses Stichwort gestolpert. Das war in einem Artikel von Norbert Häring über Manipulationen des Deutschen Wetterdienstes (DWD). In diesem Fall ging es um eine Pressemitteilung vom Donnerstag zum «viel zu warmen» Winter 2024/25.
Häring wirft der Behörde vor, dreist zu lügen und Dinge auszulassen, um die Klimaangst wach zu halten. Was der Leser beim DWD nicht erfahre, sei, dass dieser Winter kälter als die drei vorangegangenen und kälter als der Durchschnitt der letzten zehn Jahre gewesen sei. Stattdessen werde der falsche Eindruck vermittelt, es würde ungebremst immer wärmer.
Wem also der zu Ende gehende Winter eher kalt vorgekommen sein sollte, mit dessen Empfinden stimme wohl etwas nicht. Das jedenfalls wolle der DWD uns einreden, so der Wirtschaftsjournalist. Und damit sind wir beim Thema Gaslighting.
Als Gaslighting wird eine Form psychischer Manipulation bezeichnet, mit der die Opfer desorientiert und zutiefst verunsichert werden, indem ihre eigene Wahrnehmung als falsch bezeichnet wird. Der Prozess führt zu Angst und Realitätsverzerrung sowie zur Zerstörung des Selbstbewusstseins. Die Bezeichnung kommt von dem britischen Theaterstück «Gas Light» aus dem Jahr 1938, in dem ein Mann mit grausamen Psychotricks seine Frau in den Wahnsinn treibt.
Damit Gaslighting funktioniert, muss das Opfer dem Täter vertrauen. Oft wird solcher Psychoterror daher im privaten oder familiären Umfeld beschrieben, ebenso wie am Arbeitsplatz. Jedoch eignen sich die Prinzipien auch perfekt zur Manipulation der Massen. Vermeintliche Autoritäten wie Ärzte und Wissenschaftler, oder «der fürsorgliche Staat» und Institutionen wie die UNO oder die WHO wollen uns doch nichts Böses. Auch Staatsmedien, Faktenchecker und diverse NGOs wurden zu «vertrauenswürdigen Quellen» erklärt. Das hat seine Wirkung.
Warum das Thema Gaslighting derzeit scheinbar so populär ist, vermag ich nicht zu sagen. Es sind aber gerade in den letzten Tagen und Wochen auffällig viele Artikel dazu erschienen, und zwar nicht nur von Psychologen. Die Frankfurter Rundschau hat gleich mehrere publiziert, und Anwälte interessieren sich dafür offenbar genauso wie Apotheker.
Die Apotheken Umschau machte sogar auf «Medical Gaslighting» aufmerksam. Davon spreche man, wenn Mediziner Symptome nicht ernst nähmen oder wenn ein gesundheitliches Problem vom behandelnden Arzt «schnöde heruntergespielt» oder abgetan würde. Kommt Ihnen das auch irgendwie bekannt vor? Der Begriff sei allerdings irreführend, da er eine manipulierende Absicht unterstellt, die «nicht gewährleistet» sei.
Apropos Gaslighting: Die noch amtierende deutsche Bundesregierung meldete heute, es gelte, «weiter [sic!] gemeinsam daran zu arbeiten, einen gerechten und dauerhaften Frieden für die Ukraine zu erreichen». Die Ukraine, wo sich am Montag «der völkerrechtswidrige Angriffskrieg zum dritten Mal jährte», verteidige ihr Land und «unsere gemeinsamen Werte».
Merken Sie etwas? Das Demokratieverständnis mag ja tatsächlich inzwischen in beiden Ländern ähnlich traurig sein. Bezüglich Friedensbemühungen ist meine Wahrnehmung jedoch eine andere. Das muss an meinem Gedächtnis liegen.

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

2025-01-14 01:31:12Bitcoin is more than money, more than an asset, and more than a store of value. Bitcoin is a Prime Mover, an enabler and it ignites imaginations. It certainly fueled an idea in my mind. The idea integrates sensors, computational prowess, actuated machinery, power conversion, and electronic communications to form an autonomous, machined creature roaming forests and harvesting the most widespread and least energy-dense fuel source available. I call it the Forest Walker and it eats wood, and mines Bitcoin.
I know what you're thinking. Why not just put Bitcoin mining rigs where they belong: in a hosted facility sporting electricity from energy-dense fuels like natural gas, climate-controlled with excellent data piping in and out? Why go to all the trouble building a robot that digests wood creating flammable gasses fueling an engine to run a generator powering Bitcoin miners? It's all about synergy.
Bitcoin mining enables the realization of multiple, seemingly unrelated, yet useful activities. Activities considered un-profitable if not for Bitcoin as the Prime Mover. This is much more than simply mining the greatest asset ever conceived by humankind. It’s about the power of synergy, which Bitcoin plays only one of many roles. The synergy created by this system can stabilize forests' fire ecology while generating multiple income streams. That’s the realistic goal here and requires a brief history of American Forest management before continuing.
Smokey The Bear
In 1944, the Smokey Bear Wildfire Prevention Campaign began in the United States. “Only YOU can prevent forest fires” remains the refrain of the Ad Council’s longest running campaign. The Ad Council is a U.S. non-profit set up by the American Association of Advertising Agencies and the Association of National Advertisers in 1942. It would seem that the U.S. Department of the Interior was concerned about pesky forest fires and wanted them to stop. So, alongside a national policy of extreme fire suppression they enlisted the entire U.S. population to get onboard via the Ad Council and it worked. Forest fires were almost obliterated and everyone was happy, right? Wrong.
Smokey is a fantastically successful bear so forest fires became so few for so long that the fuel load - dead wood - in forests has become very heavy. So heavy that when a fire happens (and they always happen) it destroys everything in its path because the more fuel there is the hotter that fire becomes. Trees, bushes, shrubs, and all other plant life cannot escape destruction (not to mention homes and businesses). The soil microbiology doesn’t escape either as it is burned away even in deeper soils. To add insult to injury, hydrophobic waxy residues condense on the soil surface, forcing water to travel over the ground rather than through it eroding forest soils. Good job, Smokey. Well done, Sir!
Most terrestrial ecologies are “fire ecologies”. Fire is a part of these systems’ fuel load and pest management. Before we pretended to “manage” millions of acres of forest, fires raged over the world, rarely damaging forests. The fuel load was always too light to generate fires hot enough to moonscape mountainsides. Fires simply burned off the minor amounts of fuel accumulated since the fire before. The lighter heat, smoke, and other combustion gasses suppressed pests, keeping them in check and the smoke condensed into a plant growth accelerant called wood vinegar, not a waxy cap on the soil. These fires also cleared out weak undergrowth, cycled minerals, and thinned the forest canopy, allowing sunlight to penetrate to the forest floor. Without a fire’s heat, many pine tree species can’t sow their seed. The heat is required to open the cones (the seed bearing structure) of Spruce, Cypress, Sequoia, Jack Pine, Lodgepole Pine and many more. Without fire forests can’t have babies. The idea was to protect the forests, and it isn't working.
So, in a world of fire, what does an ally look like and what does it do?
Meet The Forest Walker
For the Forest Walker to work as a mobile, autonomous unit, a solid platform that can carry several hundred pounds is required. It so happens this chassis already exists but shelved.
Introducing the Legged Squad Support System (LS3). A joint project between Boston Dynamics, DARPA, and the United States Marine Corps, the quadrupedal robot is the size of a cow, can carry 400 pounds (180 kg) of equipment, negotiate challenging terrain, and operate for 24 hours before needing to refuel. Yes, it had an engine. Abandoned in 2015, the thing was too noisy for military deployment and maintenance "under fire" is never a high-quality idea. However, we can rebuild it to act as a platform for the Forest Walker; albeit with serious alterations. It would need to be bigger, probably. Carry more weight? Definitely. Maybe replace structural metal with carbon fiber and redesign much as 3D printable parts for more effective maintenance.
The original system has a top operational speed of 8 miles per hour. For our purposes, it only needs to move about as fast as a grazing ruminant. Without the hammering vibrations of galloping into battle, shocks of exploding mortars, and drunken soldiers playing "Wrangler of Steel Machines", time between failures should be much longer and the overall energy consumption much lower. The LS3 is a solid platform to build upon. Now it just needs to be pulled out of the mothballs, and completely refitted with outboard equipment.
The Small Branch Chipper
When I say “Forest fuel load” I mean the dead, carbon containing litter on the forest floor. Duff (leaves), fine-woody debris (small branches), and coarse woody debris (logs) are the fuel that feeds forest fires. Walk through any forest in the United States today and you will see quite a lot of these materials. Too much, as I have described. Some of these fuel loads can be 8 tons per acre in pine and hardwood forests and up to 16 tons per acre at active logging sites. That’s some big wood and the more that collects, the more combustible danger to the forest it represents. It also provides a technically unlimited fuel supply for the Forest Walker system.
The problem is that this detritus has to be chewed into pieces that are easily ingestible by the system for the gasification process (we’ll get to that step in a minute). What we need is a wood chipper attached to the chassis (the LS3); its “mouth”.
A small wood chipper handling material up to 2.5 - 3.0 inches (6.3 - 7.6 cm) in diameter would eliminate a substantial amount of fuel. There is no reason for Forest Walker to remove fallen trees. It wouldn’t have to in order to make a real difference. It need only identify appropriately sized branches and grab them. Once loaded into the chipper’s intake hopper for further processing, the beast can immediately look for more “food”. This is essentially kindling that would help ignite larger logs. If it’s all consumed by Forest Walker, then it’s not present to promote an aggravated conflagration.
I have glossed over an obvious question: How does Forest Walker see and identify branches and such? LiDaR (Light Detection and Ranging) attached to Forest Walker images the local area and feed those data to onboard computers for processing. Maybe AI plays a role. Maybe simple machine learning can do the trick. One thing is for certain: being able to identify a stick and cause robotic appendages to pick it up is not impossible.
Great! We now have a quadrupedal robot autonomously identifying and “eating” dead branches and other light, combustible materials. Whilst strolling through the forest, depleting future fires of combustibles, Forest Walker has already performed a major function of this system: making the forest safer. It's time to convert this low-density fuel into a high-density fuel Forest Walker can leverage. Enter the gasification process.
The Gassifier
The gasifier is the heart of the entire system; it’s where low-density fuel becomes the high-density fuel that powers the entire system. Biochar and wood vinegar are process wastes and I’ll discuss why both are powerful soil amendments in a moment, but first, what’s gasification?
Reacting shredded carbonaceous material at high temperatures in a low or no oxygen environment converts the biomass into biochar, wood vinegar, heat, and Synthesis Gas (Syngas). Syngas consists primarily of hydrogen, carbon monoxide, and methane. All of which are extremely useful fuels in a gaseous state. Part of this gas is used to heat the input biomass and keep the reaction temperature constant while the internal combustion engine that drives the generator to produce electrical power consumes the rest.
Critically, this gasification process is “continuous feed”. Forest Walker must intake biomass from the chipper, process it to fuel, and dump the waste (CO2, heat, biochar, and wood vinegar) continuously. It cannot stop. Everything about this system depends upon this continual grazing, digestion, and excretion of wastes just as a ruminal does. And, like a ruminant, all waste products enhance the local environment.
When I first heard of gasification, I didn’t believe that it was real. Running an electric generator from burning wood seemed more akin to “conspiracy fantasy” than science. Not only is gasification real, it’s ancient technology. A man named Dean Clayton first started experiments on gasification in 1699 and in 1901 gasification was used to power a vehicle. By the end of World War II, there were 500,000 Syngas powered vehicles in Germany alone because of fossil fuel rationing during the war. The global gasification market was $480 billion in 2022 and projected to be as much as $700 billion by 2030 (Vantage Market Research). Gasification technology is the best choice to power the Forest Walker because it’s self-contained and we want its waste products.
Biochar: The Waste
Biochar (AKA agricultural charcoal) is fairly simple: it’s almost pure, solid carbon that resembles charcoal. Its porous nature packs large surface areas into small, 3 dimensional nuggets. Devoid of most other chemistry, like hydrocarbons (methane) and ash (minerals), biochar is extremely lightweight. Do not confuse it with the charcoal you buy for your grill. Biochar doesn’t make good grilling charcoal because it would burn too rapidly as it does not contain the multitude of flammable components that charcoal does. Biochar has several other good use cases. Water filtration, water retention, nutrient retention, providing habitat for microscopic soil organisms, and carbon sequestration are the main ones that we are concerned with here.
Carbon has an amazing ability to adsorb (substances stick to and accumulate on the surface of an object) manifold chemistries. Water, nutrients, and pollutants tightly bind to carbon in this format. So, biochar makes a respectable filter and acts as a “battery” of water and nutrients in soils. Biochar adsorbs and holds on to seven times its weight in water. Soil containing biochar is more drought resilient than soil without it. Adsorbed nutrients, tightly sequestered alongside water, get released only as plants need them. Plants must excrete protons (H+) from their roots to disgorge water or positively charged nutrients from the biochar's surface; it's an active process.
Biochar’s surface area (where adsorption happens) can be 500 square meters per gram or more. That is 10% larger than an official NBA basketball court for every gram of biochar. Biochar’s abundant surface area builds protective habitats for soil microbes like fungi and bacteria and many are critical for the health and productivity of the soil itself.
The “carbon sequestration” component of biochar comes into play where “carbon credits” are concerned. There is a financial market for carbon. Not leveraging that market for revenue is foolish. I am climate agnostic. All I care about is that once solid carbon is inside the soil, it will stay there for thousands of years, imparting drought resiliency, fertility collection, nutrient buffering, and release for that time span. I simply want as much solid carbon in the soil because of the undeniably positive effects it has, regardless of any climactic considerations.
Wood Vinegar: More Waste
Another by-product of the gasification process is wood vinegar (Pyroligneous acid). If you have ever seen Liquid Smoke in the grocery store, then you have seen wood vinegar. Principally composed of acetic acid, acetone, and methanol wood vinegar also contains ~200 other organic compounds. It would seem intuitive that condensed, liquefied wood smoke would at least be bad for the health of all living things if not downright carcinogenic. The counter intuition wins the day, however. Wood vinegar has been used by humans for a very long time to promote digestion, bowel, and liver health; combat diarrhea and vomiting; calm peptic ulcers and regulate cholesterol levels; and a host of other benefits.
For centuries humans have annually burned off hundreds of thousands of square miles of pasture, grassland, forest, and every other conceivable terrestrial ecosystem. Why is this done? After every burn, one thing becomes obvious: the almost supernatural growth these ecosystems exhibit after the burn. How? Wood vinegar is a component of this growth. Even in open burns, smoke condenses and infiltrates the soil. That is when wood vinegar shows its quality.
This stuff beefs up not only general plant growth but seed germination as well and possesses many other qualities that are beneficial to plants. It’s a pesticide, fungicide, promotes beneficial soil microorganisms, enhances nutrient uptake, and imparts disease resistance. I am barely touching a long list of attributes here, but you want wood vinegar in your soil (alongside biochar because it adsorbs wood vinegar as well).
The Internal Combustion Engine
Conversion of grazed forage to chemical, then mechanical, and then electrical energy completes the cycle. The ICE (Internal Combustion Engine) converts the gaseous fuel output from the gasifier to mechanical energy, heat, water vapor, and CO2. It’s the mechanical energy of a rotating drive shaft that we want. That rotation drives the electric generator, which is the heartbeat we need to bring this monster to life. Luckily for us, combined internal combustion engine and generator packages are ubiquitous, delivering a defined energy output given a constant fuel input. It’s the simplest part of the system.
The obvious question here is whether the amount of syngas provided by the gasification process will provide enough energy to generate enough electrons to run the entire system or not. While I have no doubt the energy produced will run Forest Walker's main systems the question is really about the electrons left over. Will it be enough to run the Bitcoin mining aspect of the system? Everything is a budget.
CO2 Production For Growth
Plants are lollipops. No matter if it’s a tree or a bush or a shrubbery, the entire thing is mostly sugar in various formats but mostly long chain carbohydrates like lignin and cellulose. Plants need three things to make sugar: CO2, H2O and light. In a forest, where tree densities can be quite high, CO2 availability becomes a limiting growth factor. It’d be in the forest interests to have more available CO2 providing for various sugar formation providing the organism with food and structure.
An odd thing about tree leaves, the openings that allow gasses like the ever searched for CO2 are on the bottom of the leaf (these are called stomata). Not many stomata are topside. This suggests that trees and bushes have evolved to find gasses like CO2 from below, not above and this further suggests CO2 might be in higher concentrations nearer the soil.
The soil life (bacterial, fungi etc.) is constantly producing enormous amounts of CO2 and it would stay in the soil forever (eventually killing the very soil life that produces it) if not for tidal forces. Water is everywhere and whether in pools, lakes, oceans or distributed in “moist” soils water moves towards to the moon. The water in the soil and also in the water tables below the soil rise toward the surface every day. When the water rises, it expels the accumulated gasses in the soil into the atmosphere and it’s mostly CO2. It’s a good bet on how leaves developed high populations of stomata on the underside of leaves. As the water relaxes (the tide goes out) it sucks oxygenated air back into the soil to continue the functions of soil life respiration. The soil “breathes” albeit slowly.
The gasses produced by the Forest Walker’s internal combustion engine consist primarily of CO2 and H2O. Combusting sugars produce the same gasses that are needed to construct the sugars because the universe is funny like that. The Forest Walker is constantly laying down these critical construction elements right where the trees need them: close to the ground to be gobbled up by the trees.
The Branch Drones
During the last ice age, giant mammals populated North America - forests and otherwise. Mastodons, woolly mammoths, rhinos, short-faced bears, steppe bison, caribou, musk ox, giant beavers, camels, gigantic ground-dwelling sloths, glyptodons, and dire wolves were everywhere. Many were ten to fifteen feet tall. As they crashed through forests, they would effectively cleave off dead side-branches of trees, halting the spread of a ground-based fire migrating into the tree crown ("laddering") which is a death knell for a forest.
These animals are all extinct now and forests no longer have any manner of pruning services. But, if we build drones fitted with cutting implements like saws and loppers, optical cameras and AI trained to discern dead branches from living ones, these drones could effectively take over pruning services by identifying, cutting, and dropping to the forest floor, dead branches. The dropped branches simply get collected by the Forest Walker as part of its continual mission.
The drones dock on the back of the Forest Walker to recharge their batteries when low. The whole scene would look like a grazing cow with some flies bothering it. This activity breaks the link between a relatively cool ground based fire and the tree crowns and is a vital element in forest fire control.
The Bitcoin Miner
Mining is one of four monetary incentive models, making this system a possibility for development. The other three are US Dept. of the Interior, township, county, and electrical utility company easement contracts for fuel load management, global carbon credits trading, and data set sales. All the above depends on obvious questions getting answered. I will list some obvious ones, but this is not an engineering document and is not the place for spreadsheets. How much Bitcoin one Forest Walker can mine depends on everything else. What amount of biomass can we process? Will that biomass flow enough Syngas to keep the lights on? Can the chassis support enough mining ASICs and supporting infrastructure? What does that weigh and will it affect field performance? How much power can the AC generator produce?
Other questions that are more philosophical persist. Even if a single Forest Walker can only mine scant amounts of BTC per day, that pales to how much fuel material it can process into biochar. We are talking about millions upon millions of forested acres in need of fuel load management. What can a single Forest Walker do? I am not thinking in singular terms. The Forest Walker must operate as a fleet. What could 50 do? 500?
What is it worth providing a service to the world by managing forest fuel loads? Providing proof of work to the global monetary system? Seeding soil with drought and nutrient resilience by the excretion, over time, of carbon by the ton? What did the last forest fire cost?
The Mesh Network
What could be better than one bitcoin mining, carbon sequestering, forest fire squelching, soil amending behemoth? Thousands of them, but then they would need to be able to talk to each other to coordinate position, data handling, etc. Fitted with a mesh networking device, like goTenna or Meshtastic LoRa equipment enables each Forest Walker to communicate with each other.
Now we have an interconnected fleet of Forest Walkers relaying data to each other and more importantly, aggregating all of that to the last link in the chain for uplink. Well, at least Bitcoin mining data. Since block data is lightweight, transmission of these data via mesh networking in fairly close quartered environs is more than doable. So, how does data transmit to the Bitcoin Network? How do the Forest Walkers get the previous block data necessary to execute on mining?
Back To The Chain
Getting Bitcoin block data to and from the network is the last puzzle piece. The standing presumption here is that wherever a Forest Walker fleet is operating, it is NOT within cell tower range. We further presume that the nearest Walmart Wi-Fi is hours away. Enter the Blockstream Satellite or something like it.
A separate, ground-based drone will have two jobs: To stay as close to the nearest Forest Walker as it can and to provide an antennae for either terrestrial or orbital data uplink. Bitcoin-centric data is transmitted to the "uplink drone" via the mesh networked transmitters and then sent on to the uplink and the whole flow goes in the opposite direction as well; many to one and one to many.
We cannot transmit data to the Blockstream satellite, and it will be up to Blockstream and companies like it to provide uplink capabilities in the future and I don't doubt they will. Starlink you say? What’s stopping that company from filtering out block data? Nothing because it’s Starlink’s system and they could decide to censor these data. It seems we may have a problem sending and receiving Bitcoin data in back country environs.
But, then again, the utility of this system in staunching the fuel load that creates forest fires is extremely useful around forested communities and many have fiber, Wi-Fi and cell towers. These communities could be a welcoming ground zero for first deployments of the Forest Walker system by the home and business owners seeking fire repression. In the best way, Bitcoin subsidizes the safety of the communities.
Sensor Packages
LiDaR
The benefit of having a Forest Walker fleet strolling through the forest is the never ending opportunity for data gathering. A plethora of deployable sensors gathering hyper-accurate data on everything from temperature to topography is yet another revenue generator. Data is valuable and the Forest Walker could generate data sales to various government entities and private concerns.
LiDaR (Light Detection and Ranging) can map topography, perform biomass assessment, comparative soil erosion analysis, etc. It so happens that the Forest Walker’s ability to “see,” to navigate about its surroundings, is LiDaR driven and since it’s already being used, we can get double duty by harvesting that data for later use. By using a laser to send out light pulses and measuring the time it takes for the reflection of those pulses to return, very detailed data sets incrementally build up. Eventually, as enough data about a certain area becomes available, the data becomes useful and valuable.
Forestry concerns, both private and public, often use LiDaR to build 3D models of tree stands to assess the amount of harvest-able lumber in entire sections of forest. Consulting companies offering these services charge anywhere from several hundred to several thousand dollars per square kilometer for such services. A Forest Walker generating such assessments on the fly while performing its other functions is a multi-disciplinary approach to revenue generation.
pH, Soil Moisture, and Cation Exchange Sensing
The Forest Walker is quadrupedal, so there are four contact points to the soil. Why not get a pH data point for every step it takes? We can also gather soil moisture data and cation exchange capacities at unheard of densities because of sampling occurring on the fly during commission of the system’s other duties. No one is going to build a machine to do pH testing of vast tracts of forest soils, but that doesn’t make the data collected from such an endeavor valueless. Since the Forest Walker serves many functions at once, a multitude of data products can add to the return on investment component.
Weather Data
Temperature, humidity, pressure, and even data like evapotranspiration gathered at high densities on broad acre scales have untold value and because the sensors are lightweight and don’t require large power budgets, they come along for the ride at little cost. But, just like the old mantra, “gas, grass, or ass, nobody rides for free”, these sensors provide potential revenue benefits just by them being present.
I’ve touched on just a few data genres here. In fact, the question for universities, governmental bodies, and other institutions becomes, “How much will you pay us to attach your sensor payload to the Forest Walker?”
Noise Suppression
Only you can prevent Metallica filling the surrounds with 120 dB of sound. Easy enough, just turn the car stereo off. But what of a fleet of 50 Forest Walkers operating in the backcountry or near a township? 500? 5000? Each one has a wood chipper, an internal combustion engine, hydraulic pumps, actuators, and more cooling fans than you can shake a stick at. It’s a walking, screaming fire-breathing dragon operating continuously, day and night, twenty-four hours a day, three hundred sixty-five days a year. The sound will negatively affect all living things and that impacts behaviors. Serious engineering consideration and prowess must deliver a silencing blow to the major issue of noise.
It would be foolish to think that a fleet of Forest Walkers could be silent, but if not a major design consideration, then the entire idea is dead on arrival. Townships would not allow them to operate even if they solved the problem of widespread fuel load and neither would governmental entities, and rightly so. Nothing, not man nor beast, would want to be subjected to an eternal, infernal scream even if it were to end within days as the fleet moved further away after consuming what it could. Noise and heat are the only real pollutants of this system; taking noise seriously from the beginning is paramount.
Fire Safety
A “fire-breathing dragon” is not the worst description of the Forest Walker. It eats wood, combusts it at very high temperatures and excretes carbon; and it does so in an extremely flammable environment. Bad mix for one Forest Walker, worse for many. One must take extreme pains to ensure that during normal operation, a Forest Walker could fall over, walk through tinder dry brush, or get pounded into the ground by a meteorite from Krypton and it wouldn’t destroy epic swaths of trees and baby deer. I envision an ultimate test of a prototype to include dowsing it in grain alcohol while it’s wrapped up in toilet paper like a pledge at a fraternity party. If it runs for 72 hours and doesn’t set everything on fire, then maybe outside entities won’t be fearful of something that walks around forests with a constant fire in its belly.
The Wrap
How we think about what can be done with and adjacent to Bitcoin is at least as important as Bitcoin’s economic standing itself. For those who will tell me that this entire idea is without merit, I say, “OK, fine. You can come up with something, too.” What can we plug Bitcoin into that, like a battery, makes something that does not work, work? That’s the lesson I get from this entire exercise. No one was ever going to hire teams of humans to go out and "clean the forest". There's no money in that. The data collection and sales from such an endeavor might provide revenues over the break-even point but investment demands Alpha in this day and age. But, plug Bitcoin into an almost viable system and, voilà! We tip the scales to achieve lift-off.
Let’s face it, we haven’t scratched the surface of Bitcoin’s forcing function on our minds. Not because it’s Bitcoin, but because of what that invention means. The question that pushes me to approach things this way is, “what can we create that one system’s waste is another system’s feedstock?” The Forest Walker system’s only real waste is the conversion of low entropy energy (wood and syngas) into high entropy energy (heat and noise). All other output is beneficial to humanity.
Bitcoin, I believe, is the first product of a new mode of human imagination. An imagination newly forged over the past few millennia of being lied to, stolen from, distracted and otherwise mis-allocated to a black hole of the nonsensical. We are waking up.
What I have presented is not science fiction. Everything I have described here is well within the realm of possibility. The question is one of viability, at least in terms of the detritus of the old world we find ourselves departing from. This system would take a non-trivial amount of time and resources to develop. I think the system would garner extensive long-term contracts from those who have the most to lose from wildfires, the most to gain from hyperaccurate data sets, and, of course, securing the most precious asset in the world. Many may not see it that way, for they seek Alpha and are therefore blind to other possibilities. Others will see only the possibilities; of thinking in a new way, of looking at things differently, and dreaming of what comes next.

2025-02-21 19:32:23Europa – das Ganze ist eine wunderbare Idee, \ aber das war der Kommunismus auch. \ Loriot
«Europa hat fertig», könnte man unken, und das wäre nicht einmal sehr verwegen. Mit solch einer Einschätzung stünden wir nicht alleine, denn die Stimmen in diese Richtung mehren sich. Der französische Präsident Emmanuel Macron warnte schon letztes Jahr davor, dass «unser Europa sterben könnte». Vermutlich hatte er dabei andere Gefahren im Kopf als jetzt der ungarische Ministerpräsident Viktor Orbán, der ein «baldiges Ende der EU» prognostizierte. Das Ergebnis könnte allerdings das gleiche sein.
Neben vordergründigen Themenbereichen wie Wirtschaft, Energie und Sicherheit ist das eigentliche Problem jedoch die obskure Mischung aus aufgegebener Souveränität und geschwollener Arroganz, mit der europäische Politiker:innende unterschiedlicher Couleur aufzutreten pflegen. Und das Tüpfelchen auf dem i ist die bröckelnde Legitimation politischer Institutionen dadurch, dass die Stimmen großer Teile der Bevölkerung seit Jahren auf vielfältige Weise ausgegrenzt werden.
Um «UnsereDemokratie» steht es schlecht. Dass seine Mandate immer schwächer werden, merkt natürlich auch unser «Führungspersonal». Entsprechend werden die Maßnahmen zur Gängelung, Überwachung und Manipulation der Bürger ständig verzweifelter. Parallel dazu plustern sich in Paris Macron, Scholz und einige andere noch einmal mächtig in Sachen Verteidigung und «Kriegstüchtigkeit» auf.
Momentan gilt es auch, das Überschwappen covidiotischer und verschwörungsideologischer Auswüchse aus den USA nach Europa zu vermeiden. So ein «MEGA» (Make Europe Great Again) können wir hier nicht gebrauchen. Aus den Vereinigten Staaten kommen nämlich furchtbare Nachrichten. Beispielsweise wurde einer der schärfsten Kritiker der Corona-Maßnahmen kürzlich zum Gesundheitsminister ernannt. Dieser setzt sich jetzt für eine Neubewertung der mRNA-«Impfstoffe» ein, was durchaus zu einem Entzug der Zulassungen führen könnte.
Der europäischen Version von «Verteidigung der Demokratie» setzte der US-Vizepräsident J. D. Vance auf der Münchner Sicherheitskonferenz sein Verständnis entgegen: «Demokratie stärken, indem wir unseren Bürgern erlauben, ihre Meinung zu sagen». Das Abschalten von Medien, das Annullieren von Wahlen oder das Ausschließen von Menschen vom politischen Prozess schütze gar nichts. Vielmehr sei dies der todsichere Weg, die Demokratie zu zerstören.
In der Schweiz kamen seine Worte deutlich besser an als in den meisten europäischen NATO-Ländern. Bundespräsidentin Karin Keller-Sutter lobte die Rede und interpretierte sie als «Plädoyer für die direkte Demokratie». Möglicherweise zeichne sich hier eine außenpolitische Kehrtwende in Richtung integraler Neutralität ab, meint mein Kollege Daniel Funk. Das wären doch endlich mal ein paar gute Nachrichten.
Von der einstigen Idee einer europäischen Union mit engeren Beziehungen zwischen den Staaten, um Konflikte zu vermeiden und das Wohlergehen der Bürger zu verbessern, sind wir meilenweit abgekommen. Der heutige korrupte Verbund unter technokratischer Leitung ähnelt mehr einem Selbstbedienungsladen mit sehr begrenztem Zugang. Die EU-Wahlen im letzten Sommer haben daran ebenso wenig geändert, wie die Bundestagswahl am kommenden Sonntag darauf einen Einfluss haben wird.

2025-02-19 09:23:17Die «moralische Weltordnung» – eine Art Astrologie. Friedrich Nietzsche
Das Treffen der BRICS-Staaten beim Gipfel im russischen Kasan war sicher nicht irgendein politisches Event. Gastgeber Wladimir Putin habe «Hof gehalten», sagen die Einen, China und Russland hätten ihre Vorstellung einer multipolaren Weltordnung zelebriert, schreiben Andere.
In jedem Fall zeigt die Anwesenheit von über 30 Delegationen aus der ganzen Welt, dass von einer geostrategischen Isolation Russlands wohl keine Rede sein kann. Darüber hinaus haben sowohl die Anreise von UN-Generalsekretär António Guterres als auch die Meldungen und Dementis bezüglich der Beitrittsbemühungen des NATO-Staats Türkei für etwas Aufsehen gesorgt.
Im Spannungsfeld geopolitischer und wirtschaftlicher Umbrüche zeigt die neue Allianz zunehmendes Selbstbewusstsein. In Sachen gemeinsamer Finanzpolitik schmiedet man interessante Pläne. Größere Unabhängigkeit von der US-dominierten Finanzordnung ist dabei ein wichtiges Ziel.
Beim BRICS-Wirtschaftsforum in Moskau, wenige Tage vor dem Gipfel, zählte ein nachhaltiges System für Finanzabrechnungen und Zahlungsdienste zu den vorrangigen Themen. Während dieses Treffens ging der russische Staatsfonds eine Partnerschaft mit dem Rechenzentrumsbetreiber BitRiver ein, um Bitcoin-Mining-Anlagen für die BRICS-Länder zu errichten.
Die Initiative könnte ein Schritt sein, Bitcoin und andere Kryptowährungen als Alternativen zu traditionellen Finanzsystemen zu etablieren. Das Projekt könnte dazu führen, dass die BRICS-Staaten den globalen Handel in Bitcoin abwickeln. Vor dem Hintergrund der Diskussionen über eine «BRICS-Währung» wäre dies eine Alternative zu dem ursprünglich angedachten Korb lokaler Währungen und zu goldgedeckten Währungen sowie eine mögliche Ergänzung zum Zahlungssystem BRICS Pay.
Dient der Bitcoin also der Entdollarisierung? Oder droht er inzwischen, zum Gegenstand geopolitischer Machtspielchen zu werden? Angesichts der globalen Vernetzungen ist es oft schwer zu durchschauen, «was eine Show ist und was im Hintergrund von anderen Strippenziehern insgeheim gesteuert wird». Sicher können Strukturen wie Bitcoin auch so genutzt werden, dass sie den Herrschenden dienlich sind. Aber die Grundeigenschaft des dezentralisierten, unzensierbaren Peer-to-Peer Zahlungsnetzwerks ist ihm schließlich nicht zu nehmen.
Wenn es nach der EZB oder dem IWF geht, dann scheint statt Instrumentalisierung momentan eher der Kampf gegen Kryptowährungen angesagt. Jürgen Schaaf, Senior Manager bei der Europäischen Zentralbank, hat jedenfalls dazu aufgerufen, Bitcoin «zu eliminieren». Der Internationale Währungsfonds forderte El Salvador, das Bitcoin 2021 als gesetzliches Zahlungsmittel eingeführt hat, kürzlich zu begrenzenden Maßnahmen gegen das Kryptogeld auf.
Dass die BRICS-Staaten ein freiheitliches Ansinnen im Kopf haben, wenn sie Kryptowährungen ins Spiel bringen, darf indes auch bezweifelt werden. Im Abschlussdokument bekennen sich die Gipfel-Teilnehmer ausdrücklich zur UN, ihren Programmen und ihrer «Agenda 2030». Ernst Wolff nennt das «eine Bankrotterklärung korrupter Politiker, die sich dem digital-finanziellen Komplex zu 100 Prozent unterwerfen».

2025-02-15 19:05:38Auf der diesjährigen Münchner Sicherheitskonferenz geht es vor allem um die Ukraine. Protagonisten sind dabei zunächst die US-Amerikaner. Präsident Trump schockierte die Europäer kurz vorher durch ein Telefonat mit seinem Amtskollegen Wladimir Putin, während Vizepräsident Vance mit seiner Rede über Demokratie und Meinungsfreiheit für versteinerte Mienen und Empörung sorgte.
Die Bemühungen der Europäer um einen Frieden in der Ukraine halten sich, gelinde gesagt, in Grenzen. Größeres Augenmerk wird auf militärische Unterstützung, die Pflege von Feindbildern sowie Eskalation gelegt. Der deutsche Bundeskanzler Scholz reagierte auf die angekündigten Verhandlungen über einen möglichen Frieden für die Ukraine mit der Forderung nach noch höheren «Verteidigungsausgaben». Auch die amtierende Außenministerin Baerbock hatte vor der Münchner Konferenz klargestellt:
«Frieden wird es nur durch Stärke geben. (...) Bei Corona haben wir gesehen, zu was Europa fähig ist. Es braucht erneut Investitionen, die der historischen Wegmarke, vor der wir stehen, angemessen sind.»
Die Rüstungsindustrie freut sich in jedem Fall über weltweit steigende Militärausgaben. Die Kriege in der Ukraine und in Gaza tragen zu Rekordeinnahmen bei. Jetzt «winkt die Aussicht auf eine jahrelange große Nachrüstung in Europa», auch wenn der Ukraine-Krieg enden sollte, so hört man aus Finanzkreisen. In der Konsequenz kennt «die Aktie des deutschen Vorzeige-Rüstungskonzerns Rheinmetall in ihrem Anstieg offenbar gar keine Grenzen mehr». «Solche Friedensversprechen» wie das jetzige hätten in der Vergangenheit zu starken Kursverlusten geführt.
Für manche Leute sind Kriegswaffen und sonstige Rüstungsgüter Waren wie alle anderen, jedenfalls aus der Perspektive von Investoren oder Managern. Auch in diesem Bereich gibt es Startups und man spricht von Dingen wie innovativen Herangehensweisen, hocheffizienten Produktionsanlagen, skalierbaren Produktionstechniken und geringeren Stückkosten.
Wir lesen aktuell von Massenproduktion und gesteigerten Fertigungskapazitäten für Kriegsgerät. Der Motor solcher Dynamik und solchen Wachstums ist die Aufrüstung, die inzwischen permanent gefordert wird. Parallel wird die Bevölkerung verbal eingestimmt und auf Kriegstüchtigkeit getrimmt.
Das Rüstungs- und KI-Startup Helsing verkündete kürzlich eine «dezentrale Massenproduktion für den Ukrainekrieg». Mit dieser Expansion positioniere sich das Münchner Unternehmen als einer der weltweit führenden Hersteller von Kampfdrohnen. Der nächste «Meilenstein» steht auch bereits an: Man will eine Satellitenflotte im Weltraum aufbauen, zur Überwachung von Gefechtsfeldern und Truppenbewegungen.
Ebenfalls aus München stammt das als DefenseTech-Startup bezeichnete Unternehmen ARX Robotics. Kürzlich habe man in der Region die größte europäische Produktionsstätte für autonome Verteidigungssysteme eröffnet. Damit fahre man die Produktion von Militär-Robotern hoch. Diese Expansion diene auch der Lieferung der «größten Flotte unbemannter Bodensysteme westlicher Bauart» in die Ukraine.
Rüstung boomt und scheint ein Zukunftsmarkt zu sein. Die Hersteller und Vermarkter betonen, mit ihren Aktivitäten und Produkten solle die europäische Verteidigungsfähigkeit erhöht werden. Ihre Strategien sollten sogar «zum Schutz demokratischer Strukturen beitragen».

2025-01-12 21:03:36I’ve been using Notedeck for several months, starting with its extremely early and experimental alpha versions, all the way to its current, more stable alpha releases. The journey has been fascinating, as I’ve had the privilege of watching it evolve from a concept into a functional and promising tool.
In its earliest stages, Notedeck was raw—offering glimpses of its potential but still far from practical for daily use. Even then, the vision behind it was clear: a platform designed to redefine how we interact with Nostr by offering flexibility and power for all users.
I'm very bullish on Notedeck. Why? Because Will Casarin is making it! Duh! 😂
Seriously though, if we’re reimagining the web and rebuilding portions of the Internet, it’s important to recognize the potential of Notedeck. If Nostr is reimagining the web, then Notedeck is reimagining the Nostr client.
Notedeck isn’t just another Nostr app—it’s more a Nostr browser that functions more like an operating system with micro-apps. How cool is that?
Much like how Google's Chrome evolved from being a web browser with a task manager into ChromeOS, a full blown operating system, Notedeck aims to transform how we interact with the Nostr. It goes beyond individual apps, offering a foundation for a fully integrated ecosystem built around Nostr.
As a Nostr evangelist, I love to scream INTEROPERABILITY and tout every application's integrations. Well, Notedeck has the potential to be one of the best platforms to showcase these integrations in entirely new and exciting ways.
Do you want an Olas feed of images? Add the media column.
Do you want a feed of live video events? Add the zap.stream column.
Do you want Nostr Nests or audio chats? Add that column to your Notedeck.
Git? Email? Books? Chat and DMs? It's all possible.
Not everyone wants a super app though, and that’s okay. As with most things in the Nostr ecosystem, flexibility is key. Notedeck gives users the freedom to choose how they engage with it—whether it’s simply following hashtags or managing straightforward feeds. You'll be able to tailor Notedeck to fit your needs, using it as extensively or minimally as you prefer.
Notedeck is designed with a local-first approach, utilizing Nostr content stored directly on your device via the local nostrdb. This will enable a plethora of advanced tools such as search and filtering, the creation of custom feeds, and the ability to develop personalized algorithms across multiple Notedeck micro-applications—all with unparalleled flexibility.
Notedeck also supports multicast. Let's geek out for a second. Multicast is a method of communication where data is sent from one source to multiple destinations simultaneously, but only to devices that wish to receive the data. Unlike broadcast, which sends data to all devices on a network, multicast targets specific receivers, reducing network traffic. This is commonly used for efficient data distribution in scenarios like streaming, conferencing, or large-scale data synchronization between devices.
In a local first world where each device holds local copies of your nostr nodes, and each device transparently syncs with each other on the local network, each node becomes a backup. Your data becomes antifragile automatically. When a node goes down it can resync and recover from other nodes. Even if not all nodes have a complete collection, negentropy can pull down only what is needed from each device. All this can be done without internet.
-Will Casarin
In the context of Notedeck, multicast would allow multiple devices to sync their Nostr nodes with each other over a local network without needing an internet connection. Wild.
Notedeck aims to offer full customization too, including the ability to design and share custom skins, much like Winamp. Users will also be able to create personalized columns and, in the future, share their setups with others. This opens the door for power users to craft tailored Nostr experiences, leveraging their expertise in the protocol and applications. By sharing these configurations as "Starter Decks," they can simplify onboarding and showcase the best of Nostr’s ecosystem.
Nostr’s “Other Stuff” can often be difficult to discover, use, or understand. Many users doesn't understand or know how to use web browser extensions to login to applications. Let's not even get started with nsecbunkers. Notedeck will address this challenge by providing a native experience that brings these lesser-known applications, tools, and content into a user-friendly and accessible interface, making exploration seamless. However, that doesn't mean Notedeck should disregard power users that want to use nsecbunkers though - hint hint.
For anyone interested in watching Nostr be developed live, right before your very eyes, Notedeck’s progress serves as a reminder of what’s possible when innovation meets dedication. The current alpha is already demonstrating its ability to handle complex use cases, and I’m excited to see how it continues to grow as it moves toward a full release later this year.

2025-03-03 20:06:21Just leaving this summary picture up top as that's all I really want to share with this post...
I'm on a long journey of trying to heat every aspect of my life with bitcoin mining. I started just running s9 antminers in the garage, moved to using a number of Nano 3[^1] as extremely ineffective space heaters, but finally was generously given some beefcake miners for free last month.
I'm going to shove those bad boys right into my HVAC's air return, so I experimented first with a single s9 while figuring out how to power the big ones.
However, I'm using an electrician who is a friend[^2] to put in the circuit and he's not as motivated as me. In the meantime, he had me drill these holes for the conduit, which was quite fun.
Now, I'm chomping at the bit to finish this and had a big passage to run some ethernet through in the meantime. ...so....I popped another s9 on the air return just to do SOMETHING.
Anywho, thought I'd share for other aspiring low-level heat punks like myself or anybody that wants to tell me I'm killing the resale value of my house by turning the HVAC into swiss cheese.
[^1]: check out @siggy47's great post today on the next variant of that model [^2]: who was successfully orange pilled in this process, woot!

2025-02-07 19:42:11Nur wenn wir aufeinander zugehen, haben wir die Chance \ auf Überwindung der gegenseitigen Ressentiments! \ Dr. med. dent. Jens Knipphals
In Wolfsburg sollte es kürzlich eine Gesprächsrunde von Kritikern der Corona-Politik mit Oberbürgermeister Dennis Weilmann und Vertretern der Stadtverwaltung geben. Der Zahnarzt und langjährige Maßnahmenkritiker Jens Knipphals hatte diese Einladung ins Rathaus erwirkt und publiziert. Seine Motivation:
«Ich möchte die Spaltung der Gesellschaft überwinden. Dazu ist eine umfassende Aufarbeitung der Corona-Krise in der Öffentlichkeit notwendig.»
Schon früher hatte Knipphals Antworten von den Kommunalpolitikern verlangt, zum Beispiel bei öffentlichen Bürgerfragestunden. Für das erwartete Treffen im Rathaus formulierte er Fragen wie: Warum wurden fachliche Argumente der Kritiker ignoriert? Weshalb wurde deren Ausgrenzung, Diskreditierung und Entmenschlichung nicht entgegengetreten? In welcher Form übernehmen Rat und Verwaltung in Wolfsburg persönlich Verantwortung für die erheblichen Folgen der politischen Corona-Krise?
Der Termin fand allerdings nicht statt – der Bürgermeister sagte ihn kurz vorher wieder ab. Knipphals bezeichnete Weilmann anschließend als Wiederholungstäter, da das Stadtoberhaupt bereits 2022 zu einem Runden Tisch in der Sache eingeladen hatte, den es dann nie gab. Gegenüber Multipolar erklärte der Arzt, Weilmann wolle scheinbar eine öffentliche Aufarbeitung mit allen Mitteln verhindern. Er selbst sei «inzwischen absolut desillusioniert» und die einzige Lösung sei, dass die Verantwortlichen gingen.
Die Aufarbeitung der Plandemie beginne bei jedem von uns selbst, sei aber letztlich eine gesamtgesellschaftliche Aufgabe, schreibt Peter Frey, der den «Fall Wolfsburg» auch in seinem Blog behandelt. Diese Aufgabe sei indes deutlich größer, als viele glaubten. Erfreulicherweise sei der öffentliche Informationsraum inzwischen größer, trotz der weiterhin unverfrorenen Desinformations-Kampagnen der etablierten Massenmedien.
Frey erinnert daran, dass Dennis Weilmann mitverantwortlich für gravierende Grundrechtseinschränkungen wie die 2021 eingeführten 2G-Regeln in der Wolfsburger Innenstadt zeichnet. Es sei naiv anzunehmen, dass ein Funktionär einzig im Interesse der Bürger handeln würde. Als früherer Dezernent des Amtes für Wirtschaft, Digitalisierung und Kultur der Autostadt kenne Weilmann zum Beispiel die Verknüpfung von Fördergeldern mit politischen Zielsetzungen gut.
Wolfsburg wurde damals zu einem Modellprojekt des Bundesministeriums des Innern (BMI) und war Finalist im Bitkom-Wettbewerb «Digitale Stadt». So habe rechtzeitig vor der Plandemie das Projekt «Smart City Wolfsburg» anlaufen können, das der Stadt «eine Vorreiterrolle für umfassende Vernetzung und Datenerfassung» aufgetragen habe, sagt Frey. Die Vereinten Nationen verkauften dann derartige «intelligente» Überwachungs- und Kontrollmaßnahmen ebenso als Rettung in der Not wie das Magazin Forbes im April 2020:
«Intelligente Städte können uns helfen, die Coronavirus-Pandemie zu bekämpfen. In einer wachsenden Zahl von Ländern tun die intelligenten Städte genau das. Regierungen und lokale Behörden nutzen Smart-City-Technologien, Sensoren und Daten, um die Kontakte von Menschen aufzuspüren, die mit dem Coronavirus infiziert sind. Gleichzeitig helfen die Smart Cities auch dabei, festzustellen, ob die Regeln der sozialen Distanzierung eingehalten werden.»
Offensichtlich gibt es viele Aspekte zu bedenken und zu durchleuten, wenn es um die Aufklärung und Aufarbeitung der sogenannten «Corona-Pandemie» und der verordneten Maßnahmen geht. Frustration und Desillusion sind angesichts der Realitäten absolut verständlich. Gerade deswegen sind Initiativen wie die von Jens Knipphals so bewundernswert und so wichtig – ebenso wie eine seiner Kernthesen: «Wir müssen aufeinander zugehen, da hilft alles nichts».

2025-03-03 17:23:07The Atlantas FED GDP indicator GDPNow was recently adjusted to -1.5% (https://stacker.news/items/899962). Now it got revised even further down to -2.8%.
Mind you, this is a change of almost 7% down from almost 4% growth to almost 3% reduction within a month!

2025-03-06 18:38:10When developing on nostr, normally it's enough to read the NIP related to a given feature you want to build to know what has to be done. But there are some aspects of nostr development that aren't so straightforward because they depend less on specific data formats than on how different concepts are combined.
An example of this is how for a while it was considered best practice to re-publish notes when replying to them. This practice emerged before the outbox model gained traction, and was a hacky way of attempting to ensure relays had the full context required for a given note. Over time though, pubkey hints emerged as a better way to ensure other clients could find required context.
Another one of these things is "relay-based groups", or as I prefer to call it "relays-as-groups" (RAG). Such a thing doesn't really exist - there's no spec for it (although some aspects of the concept are included in NIP 29), but at the same time there are two concrete implementations (Flotilla and Chachi) which leverage several different NIPs in order to create a cohesive system for groups on nostr.
This composability is one of the neat qualities of nostr. Not only would it be unhelpful to specify how different parts of the protocol should work together, it would be impossible because of the number of possible combinations possible just from applying a little bit of common sense to the NIPs repo. No one said it was ok to put
t
tags on akind 0
. But no one's stopping you! And the semantics are basically self-evident if you understand its component parts.So, instead of writing a NIP that sets relay-based groups in stone, I'm writing this guide in order to document how I've combined different parts of the nostr protocol to create a compelling architecture for groups.
Relays
Relays already have a canonical identity, which is the relay's url. Events posted to a relay can be thought of as "posted to that group". This means that every relay is already a group. All nostr notes have already been posted to one or more groups.
One common objection to this structure is that identifying a group with a relay means that groups are dependent on the relay to continue hosting the group. In normal broadcast nostr (which forms organic permissionless groups based on user-centric social clustering), this is a very bad thing, because hosts are orthogonal to group identity. Communities are completely different. Communities actually need someone to enforce community boundaries, implement moderation, etc. Reliance on a host is a feature, not a bug (in contrast to NIP 29 groups, which tend to co-locate many groups on a single host, relays-as-groups tends to encourage one group, one host).
This doesn't mean that federation, mirrors, and migration can't be accomplished. In a sense, leaving this on the social layer is a good thing, because it adds friction to the dissolution/forking of a group. But the door is wide open to protocol additions to support those use cases for relay-based groups. One possible approach would be to follow this draft PR which specified a "federation" event relays could publish on their own behalf.
Relay keys
This draft PR to NIP 11 specifies a
self
field which represents the relay's identity. Using this, relays can publish events on their own behalf. Currently, thepubkey
field sort of does the same thing, but is overloaded as a contact field for the owner of the relay.AUTH
Relays can control access using NIP 42 AUTH. There are any number of modes a relay can operate in:
-
No auth, fully public - anyone can read/write to the group.
-
Relays may enforce broad or granular access controls with AUTH.
Relays may deny EVENTs or REQs depending on user identity. Messages returned in AUTH, CLOSED, or OK messages should be human readable. It's crucial that clients show these error messages to users. Here's how Flotilla handles failed AUTH and denied event publishing:
LIMITS could also be used in theory to help clients adapt their interface depending on user abilities and relay policy.
- AUTH with implicit access controls.
In this mode, relays may exclude matching events from REQs if the user does not have permission to view them. This can be useful for multi-use relays that host hidden rooms. This mode should be used with caution, because it can result in confusion for the end user.
See Triflector for a relay implementation that supports some of these auth policies.
Invite codes
If a user doesn't have access to a relay, they can request access using this draft NIP. This is true whether access has been explicitly or implicitly denied (although users will have to know that they should use an invite code to request access).
The above referenced NIP also contains a mechanism for users to request an invite code that they can share with other users.
The policy for these invite codes is entirely up to the relay. They may be single-use, multi-use, or require additional verification. Additional requirements can be communicated to the user in the OK message, for example directions to visit an external URL to register.
See Triflector for a relay implementation that supports invite codes.
Content
Any kind of event can be published to a relay being treated as a group, unless rejected by the relay implementation. In particular, NIP 7D was added to support basic threads, and NIP C7 for chat messages.
Since which relay an event came from determines which group it was posted to, clients need to have a mechanism for keeping track of which relay they received an event from, and should not broadcast events to other relays (unless intending to cross-post the content).
Rooms
Rooms follow NIP 29. I wish NIP 29 wasn't called "relay based groups", which is very confusing when talking about "relays as groups". It's much better to think of them as sub-groups, or as Flotilla calls them, "rooms".
Rooms have two modes - managed and unmanaged. Managed rooms follow all the rules laid out in NIP 29 about metadata published by the relay and user membership. In either case, rooms are represented by a random room id, and are posted to by including the id in an event's
h
tag. This allows rooms to switch between managed and unmanaged modes without losing any content.Managed room names come from
kind 39000
room meta events, but unmanaged rooms don't have these. Instead, room names should come from members' NIP 51kind 10009
membership lists. Tags on these lists should look like this:["group", "groupid", "wss://group.example.com", "Cat lovers"]
. If no name can be found for the room (i.e., there aren't any members), the room should be ignored by clients.Rooms present a difficulty for publishing to the relay as a whole, since content with an
h
tag can't be excluded from requests. Currently, relay-wide posts are h-tagged with_
which works for "group" clients, but not more generally. I'm not sure how to solve this other than to ask relays to support negative filters.Cross-posting
The simplest way to cross-post content from one group (or room) to another, is to quote the original note in whatever event kind is appropriate. For example, a blog post might be quoted in a
kind 9
to be cross-posted to chat, or in akind 11
to be cross-posted to a thread.kind 16
reposts can be used the same way if the reader's client renders reposts.Posting the original event to multiple relays-as-groups is trivial, since all you have to do is send the event to the relay. Posting to multiple rooms simultaneously by appending multiple
h
tags is however not recommended, since group relays/clients are incentivised to protect themselves from spam by rejecting events with multipleh
tags (similar to how events with multiplet
tags are sometimes rejected).Privacy
Currently, it's recommended to include a NIP 70
-
tag on content posted to relays-as-groups to discourage replication of relay-specific content across the network.Another slightly stronger approach would be for group relays to strip signatures in order to make events invalid (or at least deniable). For this approach to work, users would have to be able to signal that they trust relays to be honest. We could also use ZkSNARKS to validate signatures in bulk.
In any case, group posts should not be considered "private" in the same way E2EE groups might be. Relays-as-groups should be considered a good fit for low-stakes groups with many members (since trust deteriorates quickly as more people get involved).
Membership
There is currently no canonical member list published by relays (except for NIP 29 managed rooms). Instead, users keep track of their own relay and room memberships using
kind 10009
lists. Relay-level memberships are represented by anr
tag containing the relay url, and room-level memberships are represented using agroup
tag.Users can choose to advertise their membership in a RAG by using unencrypted tags, or they may keep their membership private by using encrypted tags. Advertised memberships are useful for helping people find groups based on their social graph:
User memberships should not be trusted, since they can be published unilaterally by anyone, regardless of actual access. Possible improvements in this area would be the ability to provide proof of access:
- Relays could publish member lists (although this would sacrifice member privacy)
- Relays could support a new command that allows querying a particular member's access status
- Relays could provide a proof to the member that they could then choose to publish or not
Moderation
There are two parts to moderation: reporting and taking action based on these reports.
Reporting is already covered by NIP 56. Clients should be careful about encouraging users to post reports for illegal content under their own identity, since that can itself be illegal. Relays also should not serve reports to users, since that can be used to find rather than address objectionable content.
Reports are only one mechanism for flagging objectionable content. Relay operators and administrators can use whatever heuristics they like to identify and address objectionable content. This might be via automated policies that auto-ban based on reports from high-reputation people, a client that implements NIP 86 relay management API, or by some other admin interface.
There's currently no way for moderators of a given relay to be advertised, or for a moderator's client to know that the user is a moderator (so that they can enable UI elements for in-app moderation). This could be addressed via NIP 11, LIMITS, or some other mechanism in the future.
General best practices
In general, it's very important when developing a client to assume that the relay has no special support for any of the above features, instead treating all of this stuff as progressive enhancement.
For example, if a user enters an invite code, go ahead and send it to the relay using a
kind 28934
event. If it's rejected, you know that it didn't work. But if it's accepted, you don't know that it worked - you only know that the relay allowed the user to publish that event. This is helpful, becaues it may imply that the user does indeed have access to the relay. But additional probing may be needed, and reliance on error messages down the road when something else fails unexpectedly is indispensable.This paradigm may drive some engineers nuts, because it's basically equivalent to coding your clients to reverse-engineer relay support for every feature you want to use. But this is true of nostr as a whole - anyone can put whatever weird stuff in an event and sign it. Clients have to be extremely compliant with Postell's law - doing their absolute best to accept whatever weird data or behavior shows up and handle failure in any situation. Sure, it's annoying, but it's the cost of permissionless development. What it gets us is a completely open-ended protocol, in which anything can be built, and in which every solution is tested by the market.

2025-01-31 20:02:25Im Augenblick wird mit größter Intensität, großer Umsicht \ das deutsche Volk belogen. \ Olaf Scholz im FAZ-Interview
Online-Wahlen stärken die Demokratie, sind sicher, und 61 Prozent der Wahlberechtigten sprechen sich für deren Einführung in Deutschland aus. Das zumindest behauptet eine aktuelle Umfrage, die auch über die Agentur Reuters Verbreitung in den Medien gefunden hat. Demnach würden außerdem 45 Prozent der Nichtwähler bei der Bundestagswahl ihre Stimme abgeben, wenn sie dies zum Beispiel von Ihrem PC, Tablet oder Smartphone aus machen könnten.
Die telefonische Umfrage unter gut 1000 wahlberechtigten Personen sei repräsentativ, behauptet der Auftraggeber – der Digitalverband Bitkom. Dieser präsentiert sich als eingetragener Verein mit einer beeindruckenden Liste von Mitgliedern, die Software und IT-Dienstleistungen anbieten. Erklärtes Vereinsziel ist es, «Deutschland zu einem führenden Digitalstandort zu machen und die digitale Transformation der deutschen Wirtschaft und Verwaltung voranzutreiben».
Durchgeführt hat die Befragung die Bitkom Servicegesellschaft mbH, also alles in der Familie. Die gleiche Erhebung hatte der Verband übrigens 2021 schon einmal durchgeführt. Damals sprachen sich angeblich sogar 63 Prozent für ein derartiges «Demokratie-Update» aus – die Tendenz ist demgemäß fallend. Dennoch orakelt mancher, der Gang zur Wahlurne gelte bereits als veraltet.
Die spanische Privat-Uni mit Globalisten-Touch, IE University, berichtete Ende letzten Jahres in ihrer Studie «European Tech Insights», 67 Prozent der Europäer befürchteten, dass Hacker Wahlergebnisse verfälschen könnten. Mehr als 30 Prozent der Befragten glaubten, dass künstliche Intelligenz (KI) bereits Wahlentscheidungen beeinflusst habe. Trotzdem würden angeblich 34 Prozent der unter 35-Jährigen einer KI-gesteuerten App vertrauen, um in ihrem Namen für politische Kandidaten zu stimmen.
Wie dauerhaft wird wohl das Ergebnis der kommenden Bundestagswahl sein? Diese Frage stellt sich angesichts der aktuellen Entwicklung der Migrations-Debatte und der (vorübergehend) bröckelnden «Brandmauer» gegen die AfD. Das «Zustrombegrenzungsgesetz» der Union hat das Parlament heute Nachmittag überraschenderweise abgelehnt. Dennoch muss man wohl kein ausgesprochener Pessimist sein, um zu befürchten, dass die Entscheidungen der Bürger von den selbsternannten Verteidigern der Demokratie künftig vielleicht nicht respektiert werden, weil sie nicht gefallen.
Bundesweit wird jetzt zu «Brandmauer-Demos» aufgerufen, die CDU gerät unter Druck und es wird von Übergriffen auf Parteibüros und Drohungen gegen Mitarbeiter berichtet. Sicherheitsbehörden warnen vor Eskalationen, die Polizei sei «für ein mögliches erhöhtes Aufkommen von Straftaten gegenüber Politikern und gegen Parteigebäude sensibilisiert».
Der Vorwand «unzulässiger Einflussnahme» auf Politik und Wahlen wird als Argument schon seit einiger Zeit aufgebaut. Der Manipulation schuldig befunden wird neben Putin und Trump auch Elon Musk, was lustigerweise ausgerechnet Bill Gates gerade noch einmal bekräftigt und als «völlig irre» bezeichnet hat. Man stelle sich die Diskussionen um die Gültigkeit von Wahlergebnissen vor, wenn es Online-Verfahren zur Stimmabgabe gäbe. In der Schweiz wird «E-Voting» seit einigen Jahren getestet, aber wohl bisher mit wenig Erfolg.
Die politische Brandstiftung der letzten Jahre zahlt sich immer mehr aus. Anstatt dringende Probleme der Menschen zu lösen – zu denen auch in Deutschland die weit verbreitete Armut zählt –, hat die Politik konsequent polarisiert und sich auf Ausgrenzung und Verhöhnung großer Teile der Bevölkerung konzentriert. Basierend auf Ideologie und Lügen werden abweichende Stimmen unterdrückt und kriminalisiert, nicht nur und nicht erst in diesem Augenblick. Die nächsten Wochen dürften ausgesprochen spannend werden.

2025-01-24 20:59:01Menschen tun alles, egal wie absurd, \ um ihrer eigenen Seele nicht zu begegnen. \ Carl Gustav Jung
«Extremer Reichtum ist eine Gefahr für die Demokratie», sagen über die Hälfte der knapp 3000 befragten Millionäre aus G20-Staaten laut einer Umfrage der «Patriotic Millionaires». Ferner stellte dieser Zusammenschluss wohlhabender US-Amerikaner fest, dass 63 Prozent jener Millionäre den Einfluss von Superreichen auf US-Präsident Trump als Bedrohung für die globale Stabilität ansehen.
Diese Besorgnis haben 370 Millionäre und Milliardäre am Dienstag auch den in Davos beim WEF konzentrierten Privilegierten aus aller Welt übermittelt. In einem offenen Brief forderten sie die «gewählten Führer» auf, die Superreichen – also sie selbst – zu besteuern, um «die zersetzenden Auswirkungen des extremen Reichtums auf unsere Demokratien und die Gesellschaft zu bekämpfen». Zum Beispiel kontrolliere eine handvoll extrem reicher Menschen die Medien, beeinflusse die Rechtssysteme in unzulässiger Weise und verwandele Recht in Unrecht.
Schon 2019 beanstandete der bekannte Historiker und Schriftsteller Ruthger Bregman an einer WEF-Podiumsdiskussion die Steuervermeidung der Superreichen. Die elitäre Veranstaltung bezeichnete er als «Feuerwehr-Konferenz, bei der man nicht über Löschwasser sprechen darf.» Daraufhin erhielt Bregman keine Einladungen nach Davos mehr. Auf seine Aussagen machte der Schweizer Aktivist Alec Gagneux aufmerksam, der sich seit Jahrzehnten kritisch mit dem WEF befasst. Ihm wurde kürzlich der Zutritt zu einem dreiteiligen Kurs über das WEF an der Volkshochschule Region Brugg verwehrt.
Nun ist die Erkenntnis, dass mit Geld politischer Einfluss einhergeht, alles andere als neu. Und extremer Reichtum macht die Sache nicht wirklich besser. Trotzdem hat man über Initiativen wie Patriotic Millionaires oder Taxmenow bisher eher selten etwas gehört, obwohl es sie schon lange gibt. Auch scheint es kein Problem, wenn ein Herr Gates fast im Alleingang versucht, globale Gesundheits-, Klima-, Ernährungs- oder Bevölkerungspolitik zu betreiben – im Gegenteil. Im Jahr, als der Milliardär Donald Trump zum zweiten Mal ins Weiße Haus einzieht, ist das Echo in den Gesinnungsmedien dagegen enorm – und uniform, wer hätte das gedacht.
Der neue US-Präsident hat jedoch «Davos geerdet», wie Achgut es nannte. In seiner kurzen Rede beim Weltwirtschaftsforum verteidigte er seine Politik und stellte klar, er habe schlicht eine «Revolution des gesunden Menschenverstands» begonnen. Mit deutlichen Worten sprach er unter anderem von ersten Maßnahmen gegen den «Green New Scam», und von einem «Erlass, der jegliche staatliche Zensur beendet»:
«Unsere Regierung wird die Äußerungen unserer eigenen Bürger nicht mehr als Fehlinformation oder Desinformation bezeichnen, was die Lieblingswörter von Zensoren und derer sind, die den freien Austausch von Ideen und, offen gesagt, den Fortschritt verhindern wollen.»
Wie der «Trumpismus» letztlich einzuordnen ist, muss jeder für sich selbst entscheiden. Skepsis ist definitiv angebracht, denn «einer von uns» sind weder der Präsident noch seine auserwählten Teammitglieder. Ob sie irgendeinen Sumpf trockenlegen oder Staatsverbrechen aufdecken werden oder was aus WHO- und Klimaverträgen wird, bleibt abzuwarten.
Das WHO-Dekret fordert jedenfalls die Übertragung der Gelder auf «glaubwürdige Partner», die die Aktivitäten übernehmen könnten. Zufällig scheint mit «Impfguru» Bill Gates ein weiterer Harris-Unterstützer kürzlich das Lager gewechselt zu haben: Nach einem gemeinsamen Abendessen zeigte er sich «beeindruckt» von Trumps Interesse an der globalen Gesundheit.
Mit dem Projekt «Stargate» sind weitere dunkle Wolken am Erwartungshorizont der Fangemeinde aufgezogen. Trump hat dieses Joint Venture zwischen den Konzernen OpenAI, Oracle, und SoftBank als das «größte KI-Infrastrukturprojekt der Geschichte» angekündigt. Der Stein des Anstoßes: Oracle-CEO Larry Ellison, der auch Fan von KI-gestützter Echtzeit-Überwachung ist, sieht einen weiteren potenziellen Einsatz der künstlichen Intelligenz. Sie könne dazu dienen, Krebserkrankungen zu erkennen und individuelle mRNA-«Impfstoffe» zur Behandlung innerhalb von 48 Stunden zu entwickeln.
Warum bitte sollten sich diese superreichen «Eliten» ins eigene Fleisch schneiden und direkt entgegen ihren eigenen Interessen handeln? Weil sie Menschenfreunde, sogenannte Philanthropen sind? Oder vielleicht, weil sie ein schlechtes Gewissen haben und ihre Schuld kompensieren müssen? Deswegen jedenfalls brauchen «Linke» laut Robert Willacker, einem deutschen Politikberater mit brasilianischen Wurzeln, rechte Parteien – ein ebenso überraschender wie humorvoller Erklärungsansatz.
Wenn eine Krähe der anderen kein Auge aushackt, dann tut sie das sich selbst noch weniger an. Dass Millionäre ernsthaft ihre eigene Besteuerung fordern oder Machteliten ihren eigenen Einfluss zugunsten anderer einschränken würden, halte ich für sehr unwahrscheinlich. So etwas glaube ich erst, wenn zum Beispiel die Rüstungsindustrie sich um Friedensverhandlungen bemüht, die Pharmalobby sich gegen institutionalisierte Korruption einsetzt, Zentralbanken ihre CBDC-Pläne für Bitcoin opfern oder der ÖRR die Abschaffung der Rundfunkgebühren fordert.

2025-01-08 18:17:52Necessário
- Um Android que você não use mais (a câmera deve estar funcionando).
- Um cartão microSD (opcional, usado apenas uma vez).
- Um dispositivo para acompanhar seus fundos (provavelmente você já tem um).
Algumas coisas que você precisa saber
- O dispositivo servirá como um assinador. Qualquer movimentação só será efetuada após ser assinada por ele.
- O cartão microSD será usado para transferir o APK do Electrum e garantir que o aparelho não terá contato com outras fontes de dados externas após sua formatação. Contudo, é possível usar um cabo USB para o mesmo propósito.
- A ideia é deixar sua chave privada em um dispositivo offline, que ficará desligado em 99% do tempo. Você poderá acompanhar seus fundos em outro dispositivo conectado à internet, como seu celular ou computador pessoal.
O tutorial será dividido em dois módulos:
- Módulo 1 - Criando uma carteira fria/assinador.
- Módulo 2 - Configurando um dispositivo para visualizar seus fundos e assinando transações com o assinador.
No final, teremos:
- Uma carteira fria que também servirá como assinador.
- Um dispositivo para acompanhar os fundos da carteira.
Módulo 1 - Criando uma carteira fria/assinador
-
Baixe o APK do Electrum na aba de downloads em https://electrum.org/. Fique à vontade para verificar as assinaturas do software, garantindo sua autenticidade.
-
Formate o cartão microSD e coloque o APK do Electrum nele. Caso não tenha um cartão microSD, pule este passo.
- Retire os chips e acessórios do aparelho que será usado como assinador, formate-o e aguarde a inicialização.
- Durante a inicialização, pule a etapa de conexão ao Wi-Fi e rejeite todas as solicitações de conexão. Após isso, você pode desinstalar aplicativos desnecessários, pois precisará apenas do Electrum. Certifique-se de que Wi-Fi, Bluetooth e dados móveis estejam desligados. Você também pode ativar o modo avião.\ (Curiosidade: algumas pessoas optam por abrir o aparelho e danificar a antena do Wi-Fi/Bluetooth, impossibilitando essas funcionalidades.)
- Insira o cartão microSD com o APK do Electrum no dispositivo e instale-o. Será necessário permitir instalações de fontes não oficiais.
- No Electrum, crie uma carteira padrão e gere suas palavras-chave (seed). Anote-as em um local seguro. Caso algo aconteça com seu assinador, essas palavras permitirão o acesso aos seus fundos novamente. (Aqui entra seu método pessoal de backup.)
Módulo 2 - Configurando um dispositivo para visualizar seus fundos e assinando transações com o assinador.
-
Criar uma carteira somente leitura em outro dispositivo, como seu celular ou computador pessoal, é uma etapa bastante simples. Para este tutorial, usaremos outro smartphone Android com Electrum. Instale o Electrum a partir da aba de downloads em https://electrum.org/ ou da própria Play Store. (ATENÇÃO: O Electrum não existe oficialmente para iPhone. Desconfie se encontrar algum.)
-
Após instalar o Electrum, crie uma carteira padrão, mas desta vez escolha a opção Usar uma chave mestra.
- Agora, no assinador que criamos no primeiro módulo, exporte sua chave pública: vá em Carteira > Detalhes da carteira > Compartilhar chave mestra pública.
-
Escaneie o QR gerado da chave pública com o dispositivo de consulta. Assim, ele poderá acompanhar seus fundos, mas sem permissão para movimentá-los.
-
Para receber fundos, envie Bitcoin para um dos endereços gerados pela sua carteira: Carteira > Addresses/Coins.
-
Para movimentar fundos, crie uma transação no dispositivo de consulta. Como ele não possui a chave privada, será necessário assiná-la com o dispositivo assinador.
- No assinador, escaneie a transação não assinada, confirme os detalhes, assine e compartilhe. Será gerado outro QR, desta vez com a transação já assinada.
- No dispositivo de consulta, escaneie o QR da transação assinada e transmita-a para a rede.
Conclusão
Pontos positivos do setup:
- Simplicidade: Basta um dispositivo Android antigo.
- Flexibilidade: Funciona como uma ótima carteira fria, ideal para holders.
Pontos negativos do setup:
- Padronização: Não utiliza seeds no padrão BIP-39, você sempre precisará usar o electrum.
- Interface: A aparência do Electrum pode parecer antiquada para alguns usuários.
Nesse ponto, temos uma carteira fria que também serve para assinar transações. O fluxo de assinar uma transação se torna: Gerar uma transação não assinada > Escanear o QR da transação não assinada > Conferir e assinar essa transação com o assinador > Gerar QR da transação assinada > Escanear a transação assinada com qualquer outro dispositivo que possa transmiti-la para a rede.
Como alguns devem saber, uma transação assinada de Bitcoin é praticamente impossível de ser fraudada. Em um cenário catastrófico, você pode mesmo que sem internet, repassar essa transação assinada para alguém que tenha acesso à rede por qualquer meio de comunicação. Mesmo que não queiramos que isso aconteça um dia, esse setup acaba por tornar essa prática possível.

2025-03-06 17:38:10What Is Dark Nostr?
Dark Nostr can be described as the unintended adverse effects that arise from creating systems designed to resist censorship and promote freedom. These systems often rely on algorithms and micropayments to function, but their very design can inadvertently spawn phenomena that are unpredictable, uncontrollable, and sometimes downright weird.
Think of it as the Yin to the Yang of decentralized freedom—a necessary shadow cast by the bright ideals of liberation. While freedom protocols aim to empower individuals, they also open the door to consequences that aren’t always sunshine and rainbows.
An Emergent Phenomenon
The fascinating thing about Dark Nostr is its emergent nature. This means it’s not something you can fully define or predict ahead of time; instead, it arises organically as decentralized systems are implemented and evolve. Like watching clouds form shapes in the sky, GM miners panhandle for sats or shower girls in the global feed, you can only observe it as it happens—and even then, its contours remain elusive.
Emergent phenomena are tricky beasts. While simplicity is at the core of the protocol layer darkness is born on the edge where complexity thrives—where individual components interact in ways that produce unpredictable outcomes. In this case, Dark Nostr encapsulates everything from algorithmic quirks and micropayment dynamics to unforeseen social consequences within decentralized ecosystems.
Studying Dark Nostr: Memes as Cultural Artifacts
Here’s where things get anthropologically juicy: much of what we know about Dark Nostr comes not from academic papers or technical manuals but from memes. Yes, memes—the internet’s favorite medium for cultural commentary—have become a lens through which this phenomenon is being observed and studied.
Memes act as modern-day hieroglyphs, distilling complex ideas into bite-sized cultural artifacts that reflect collective sentiment. When communities encounter something as nebulous as Dark Nostr, they turn to humor and symbolism to make sense of it. In doing so, they create a shared narrative—a way to grapple with the shadow side of decentralization without losing sight of its promise.
Why Does It Matter?
Dark Nostr isn’t just an abstract concept for philosophers or tech enthusiasts—it’s a reminder that every innovation comes with trade-offs. While decentralized systems aim to empower individuals by resisting censorship and central control, they also carry risks that must be acknowledged:
- Algorithmic Chaos: Algorithms designed for freedom might amplify harmful content or create echo chambers.
- Micropayment Pitfalls: Financial incentives could lead to exploitation or manipulation within these systems.
- Social Dynamics: The lack of centralized control might enable bad actors or foster unforeseen societal shifts.Understanding Dark Nostr is crucial for anyone involved in building or using decentralized technologies. It challenges us to balance freedom with responsibility and reminds us that even the most well-intentioned systems have their shadow side.
Conclusion: Embracing the Shadow
Dark Nostr is more than just a cautionary tale—it’s a fascinating glimpse into the complexities of human interaction with technology. As an emergent phenomenon, it invites us to remain vigilant and adaptive as we navigate the uncharted waters of decentralization.
By studying its manifestations through cultural artifacts like memes and engaging in thoughtful reflection, we can better prepare for both its opportunities and risks. After all, every great innovation needs its shadow—it’s what makes progress real, messy, and human.
So here we stand before Dark Nostr: may we study it wisely, meme it relentlessly, and learn from its lessons as we build the future together.
Stay Vigilent Nostr.....

Inter-op All The Things
Nostr is a new open social protocol for the internet. This open nature exciting because of the opportunities for interoperability with other technologies. In Using NFC Cards with Nostr I explored the
nostr:
URI to launch Nostr clients from a card tap.The interoperability of Nostr doesn't stop there. The internet has many super-powers, and Nostr is open to all of them. Simply, there's no one to stop it. There is no one in charge, there are no permissioned APIs, and there are no risks of being de-platformed. If you can imagine technologies that would work well with Nostr, then any and all of them can ride on or alongside Nostr rails.
My mental model for why this is special is Google Wave ~2010. Google Wave was to be the next big platform. Lars was running it and had a big track record from Maps. I was excited for it. Then, Google pulled the plug. And, immediately all the time and capital invested in understanding and building on the platform was wasted.
This cannot happen to Nostr, as there is no one to pull the plug, and maybe even no plug to pull.
So long as users demand Nostr, Nostr will exist, and that is a pretty strong guarantee. It makes it worthwhile to invest in bringing Nostr into our other applications.
All we need are simple ways to plug things together.
Nostr and Workflow Automation
Workflow automation is about helping people to streamline their work. As a user, the most common way I achieve this is by connecting disparate systems together. By setting up one system to trigger another or to move data between systems, I can solve for many different problems and become way more effective.
n8n for workflow automation
Many workflow automation tools exist. My favourite is n8n. n8n is a low/no-code workflow automation platform which allows you to build all kinds of workflows. You can use it for free, you can self-host it, it has a user-friendly UI and useful API. Vs Zapier it can be far more elaborate. Vs Make.com I find it to be more intuitive in how it abstracts away the right parts of the code, but still allows you to code when you need to.
Most importantly you can plug anything into n8n: You have built-in nodes for specific applications. HTTP nodes for any other API-based service. And community nodes built by individual community members for any other purpose you can imagine.
Eating my own dogfood
It's very clear to me that there is a big design space here just demanding to be explored. If you could integrate Nostr with anything, what would you do?
In my view the best way for anyone to start anything is by solving their own problem first (aka "scratching your own itch" and "eating your own dogfood"). As I get deeper into Nostr I find myself controlling multiple Npubs – to date I have a personal Npub, a brand Npub for a community I am helping, an AI assistant Npub, and various testing Npubs. I need ways to delegate access to those Npubs without handing over the keys, ways to know if they're mentioned, and ways to know if they're posting.
I can build workflows with n8n to solve these issues for myself to start with, and keep expanding from there as new needs come up.
Running n8n with Nostrobots
I am mostly non-technical with a very helpful AI. To set up n8n to work with Nostr and operate these workflows should be possible for anyone with basic technology skills.
- I have a cheap VPS which currently runs my HAVEN Nostr Relay and Albyhub Lightning Node in Docker containers,
- My objective was to set up n8n to run alongside these in a separate Docker container on the same server, install the required nodes, and then build and host my workflows.
Installing n8n
Self-hosting n8n could not be easier. I followed n8n's Docker-Compose installation docs–
- Install Docker and Docker-Compose if you haven't already,
- Create your
docker-compose.yml
and.env
files from the docs, - Create your data folder
sudo docker volume create n8n_data
, - Start your container with
sudo docker compose up -d
, - Your n8n instance should be online at port
5678
.
n8n is free to self-host but does require a license. Enter your credentials into n8n to get your free license key. You should now have access to the Workflow dashboard and can create and host any kind of workflows from there.
Installing Nostrobots
To integrate n8n nicely with Nostr, I used the Nostrobots community node by Ocknamo.
In n8n parlance a "node" enables certain functionality as a step in a workflow e.g. a "set" node sets a variable, a "send email" node sends an email. n8n comes with all kinds of "official" nodes installed by default, and Nostr is not amongst them. However, n8n also comes with a framework for community members to create their own "community" nodes, which is where Nostrobots comes in.
You can only use a community node in a self-hosted n8n instance (which is what you have if you are running in Docker on your own server, but this limitation does prevent you from using n8n's own hosted alternative).
To install a community node, see n8n community node docs. From your workflow dashboard–
- Click the "..." in the bottom left corner beside your username, and click "settings",
- Cilck "community nodes" left sidebar,
- Click "Install",
- Enter the "npm Package Name" which is
n8n-nodes-nostrobots
, - Accept the risks and click "Install",
- Nostrobots is now added to your n8n instance.
Using Nostrobots
Nostrobots gives you nodes to help you build Nostr-integrated workflows–
- Nostr Write – for posting Notes to the Nostr network,
- Nostr Read – for reading Notes from the Nostr network, and
- Nostr Utils – for performing certain conversions you may need (e.g. from bech32 to hex).
Nostrobots has good documentation on each node which focuses on simple use cases.
Each node has a "convenience mode" by default. For example, the "Read" Node by default will fetch Kind 1 notes by a simple filter, in Nostrobots parlance a "Strategy". For example, with Strategy set to "Mention" the node will accept a pubkey and fetch all Kind 1 notes that Mention the pubkey within a time period. This is very good for quick use.
What wasn't clear to me initially (until Ocknamo helped me out) is that advanced use cases are also possible.
Each node also has an advanced mode. For example, the "Read" Node can have "Strategy" set to "RawFilter(advanced)". Now the node will accept json (anything you like that complies with NIP-01). You can use this to query Notes (Kind 1) as above, and also Profiles (Kind 0), Follow Lists (Kind 3), Reactions (Kind 7), Zaps (Kind 9734/9735), and anything else you can think of.
Creating and adding workflows
With n8n and Nostrobots installed, you can now create or add any kind of Nostr Workflow Automation.
- Click "Add workflow" to go to the workflow builder screen,
- If you would like to build your own workflow, you can start with adding any node. Click "+" and see what is available. Type "Nostr" to explore the Nostrobots nodes you have added,
- If you would like to add workflows that someone else has built, click "..." in the top right. Then click "import from URL" and paste in the URL of any workflow you would like to use (including the ones I share later in this article).
Nostr Workflow Automations
It's time to build some things!
A simple form to post a note to Nostr
I started very simply. I needed to delegate the ability to post to Npubs that I own in order that a (future) team can test things for me. I don't want to worry about managing or training those people on how to use keys, and I want to revoke access easily.
I needed a basic form with credentials that posted a Note.
For this I can use a very simple workflow–
- A n8n Form node – Creates a form for users to enter the note they wish to post. Allows for the form to be protected by a username and password. This node is the workflow "trigger" so that the workflow runs each time the form is submitted.
- A Set node – Allows me to set some variables, in this case I set the relays that I intend to use. I typically add a Set node immediately following the trigger node, and put all the variables I need in this. It helps to make the workflows easier to update and maintain.
- A Nostr Write node (from Nostrobots) – Writes a Kind-1 note to the Nostr network. It accepts Nostr credentials, the output of the Form node, and the relays from the Set node, and posts the Note to those relays.
Once the workflow is built, you can test it with the testing form URL, and set it to "Active" to use the production form URL. That's it. You can now give posting access to anyone for any Npub. To revoke access, simply change the credentials or set to workflow to "Inactive".
It may also be the world's simplest Nostr client.
You can find the Nostr Form to Post a Note workflow here.
Push notifications on mentions and new notes
One of the things Nostr is not very good at is push notifications. Furthermore I have some unique itches to scratch. I want–
- To make sure I never miss a note addressed to any of my Npubs – For this I want a push notification any time any Nostr user mentions any of my Npubs,
- To make sure I always see all notes from key accounts – For this I need a push notification any time any of my Npubs post any Notes to the network,
- To get these notifications on all of my devices – Not just my phone where my Nostr regular client lives, but also on each of my laptops to suit wherever I am working that day.
I needed to build a Nostr push notifications solution.
To build this workflow I had to string a few ideas together–
- Triggering the node on a schedule – Nostrobots does not include a trigger node. As every workflow starts with a trigger we needed a different method. I elected to run the workflow on a schedule of every 10-minutes. Frequent enough to see Notes while they are hot, but infrequent enough to not burden public relays or get rate-limited,
- Storing a list of Npubs in a Nostr list – I needed a way to store the list of Npubs that trigger my notifications. I initially used an array defined in the workflow, this worked fine. Then I decided to try Nostr lists (NIP-51, kind 30000). By defining my list of Npubs as a list published to Nostr I can control my list from within a Nostr client (e.g. Listr.lol or Nostrudel.ninja). Not only does this "just work", but because it's based on Nostr lists automagically Amethyst client allows me to browse that list as a Feed, and everyone I add gets notified in their Mentions,
- Using specific relays – I needed to query the right relays, including my own HAVEN relay inbox for notes addressed to me, and wss://purplepag.es for Nostr profile metadata,
- Querying Nostr events (with Nostrobots) – I needed to make use of many different Nostr queries and use quite a wide range of what Nostrobots can do–
- I read the EventID of my Kind 30000 list, to return the desired pubkeys,
- For notifications on mentions, I read all Kind 1 notes that mention that pubkey,
- For notifications on new notes, I read all Kind 1 notes published by that pubkey,
- Where there are notes, I read the Kind 0 profile metadata event of that pubkey to get the displayName of the relevant Npub,
- I transform the EventID into a Nevent to help clients find it.
- Using the Nostr URI – As I did with my NFC card article, I created a link with the
nostr:
URI prefix so that my phone's native client opens the link by default, - Push notifications solution – I needed a push notifications solution. I found many with n8n integrations and chose to go with Pushover which supports all my devices, has a free trial, and is unfairly cheap with a $5-per-device perpetual license.
Once the workflow was built, lists published, and Pushover installed on my phone, I was fully set up with push notifications on Nostr. I have used these workflows for several weeks now and made various tweaks as I went. They are feeling robust and I'd welcome you to give them a go.
You can find the Nostr Push Notification If Mentioned here and If Posts a Note here.
In speaking with other Nostr users while I was building this, there are all kind of other needs for push notifications too – like on replies to a certain bookmarked note, or when a followed Npub starts streaming on zap.stream. These are all possible.
Use my workflows
I have open sourced all my workflows at my Github with MIT license and tried to write complete docs, so that you can import them into your n8n and configure them for your own use.
To import any of my workflows–
- Click on the workflow of your choice, e.g. "Nostr_Push_Notify_If_Mentioned.json",
- Click on the "raw" button to view the raw JSON, ex any Github page layout,
- Copy that URL,
- Enter that URL in the "import from URL" dialog mentioned above.
To configure them–
- Prerequisites, credentials, and variables are all stated,
- In general any variables required are entered into a Set Node that follows the trigger node,
- Pushover has some extra setup but is very straightforward and documented in the workflow.
What next?
Over my first four blogs I explored creating a good Nostr setup with Vanity Npub, Lightning Payments, Nostr Addresses at Your Domain, and Personal Nostr Relay.
Then in my latest two blogs I explored different types of interoperability with NFC cards and now n8n Workflow Automation.
Thinking ahead n8n can power any kind of interoperability between Nostr and any other legacy technology solution. On my mind as I write this:
- Further enhancements to posting and delegating solutions and forms (enhanced UI or different note kinds),
- Automated or scheduled posting (such as auto-liking everything Lyn Alden posts),
- Further enhancements to push notifications, on new and different types of events (such as notifying me when I get a new follower, on replies to certain posts, or when a user starts streaming),
- All kinds of bridges, such as bridging notes to and from Telegram, Slack, or Campfire. Or bridging RSS or other event feeds to Nostr,
- All kinds of other automation (such as BlackCoffee controlling a coffee machine),
- All kinds of AI Assistants and Agents,
In fact I have already released an open source workflow for an AI Assistant, and will share more about that in my next blog.
Please be sure to let me know if you think there's another Nostr topic you'd like to see me tackle.
GM Nostr.

2025-01-18 09:34:51Die grauenvollste Aussicht ist die der Technokratie – \ einer kontrollierenden Herrschaft, \ die durch verstümmelte und verstümmelnde Geister ausgeübt wird. \ Ernst Jünger
«Davos ist nicht mehr sexy», das Weltwirtschaftsforum (WEF) mache Davos kaputt, diese Aussagen eines Einheimischen las ich kürzlich in der Handelszeitung. Während sich einige vor Ort enorm an der «teuersten Gewerbeausstellung der Welt» bereicherten, würden die negativen Begleiterscheinungen wie Wohnungsnot und Niedergang der lokalen Wirtschaft immer deutlicher.
Nächsten Montag beginnt in dem Schweizer Bergdorf erneut ein Jahrestreffen dieses elitären Clubs der Konzerne, bei dem man mit hochrangigen Politikern aus aller Welt und ausgewählten Vertretern der Systemmedien zusammenhocken wird. Wie bereits in den vergangenen vier Jahren wird die Präsidentin der EU-Kommission, Ursula von der Leyen, in Begleitung von Klaus Schwab ihre Grundsatzansprache halten.
Der deutsche WEF-Gründer hatte bei dieser Gelegenheit immer höchst lobende Worte für seine Landsmännin: 2021 erklärte er sich «stolz, dass Europa wieder unter Ihrer Führung steht» und 2022 fand er es bemerkenswert, was sie erreicht habe angesichts des «erstaunlichen Wandels», den die Welt in den vorangegangenen zwei Jahren erlebt habe; es gebe nun einen «neuen europäischen Geist».
Von der Leyens Handeln während der sogenannten Corona-«Pandemie» lobte Schwab damals bereits ebenso, wie es diese Woche das Karlspreis-Direktorium tat, als man der Beschuldigten im Fall Pfizergate die diesjährige internationale Auszeichnung «für Verdienste um die europäische Einigung» verlieh. Außerdem habe sie die EU nicht nur gegen den «Aggressor Russland», sondern auch gegen die «innere Bedrohung durch Rassisten und Demagogen» sowie gegen den Klimawandel verteidigt.
Jene Herausforderungen durch «Krisen epochalen Ausmaßes» werden indes aus dem Umfeld des WEF nicht nur herbeigeredet – wie man alljährlich zur Zeit des Davoser Treffens im Global Risks Report nachlesen kann, der zusammen mit dem Versicherungskonzern Zurich erstellt wird. Seit die Globalisten 2020/21 in der Praxis gesehen haben, wie gut eine konzertierte und konsequente Angst-Kampagne funktionieren kann, geht es Schlag auf Schlag. Sie setzen alles daran, Schwabs goldenes Zeitfenster des «Great Reset» zu nutzen.
Ziel dieses «großen Umbruchs» ist die totale Kontrolle der Technokraten über die Menschen unter dem Deckmantel einer globalen Gesundheitsfürsorge. Wie aber könnte man so etwas erreichen? Ein Mittel dazu ist die «kreative Zerstörung». Weitere unabdingbare Werkzeug sind die Einbindung, ja Gleichschaltung der Medien und der Justiz.
Ein «Great Mental Reset» sei die Voraussetzung dafür, dass ein Großteil der Menschen Einschränkungen und Manipulationen wie durch die Corona-Maßnahmen praktisch kritik- und widerstandslos hinnehme, sagt der Mediziner und Molekulargenetiker Michael Nehls. Er meint damit eine regelrechte Umprogrammierung des Gehirns, wodurch nach und nach unsere Individualität und unser soziales Bewusstsein eliminiert und durch unreflektierten Konformismus ersetzt werden.
Der aktuelle Zustand unserer Gesellschaften ist auch für den Schweizer Rechtsanwalt Philipp Kruse alarmierend. Durch den Umgang mit der «Pandemie» sieht er die Grundlagen von Recht und Vernunft erschüttert, die Rechtsstaatlichkeit stehe auf dem Prüfstand. Seiner dringenden Mahnung an alle Bürger, die Prinzipien von Recht und Freiheit zu verteidigen, kann ich mich nur anschließen.

2024-12-31 17:03:46Here are my predictions for Nostr in 2025:
Decentralization: The outbox and inbox communication models, sometimes referred to as the Gossip model, will become the standard across the ecosystem. By the end of 2025, all major clients will support these models, providing seamless communication and enhanced decentralization. Clients that do not adopt outbox/inbox by then will be regarded as outdated or legacy systems.
Privacy Standards: Major clients such as Damus and Primal will move away from NIP-04 DMs, adopting more secure protocol possibilities like NIP-17 or NIP-104. These upgrades will ensure enhanced encryption and metadata protection. Additionally, NIP-104 MLS tools will drive the development of new clients and features, providing users with unprecedented control over the privacy of their communications.
Interoperability: Nostr's ecosystem will become even more interconnected. Platforms like the Olas image-sharing service will expand into prominent clients such as Primal, Damus, Coracle, and Snort, alongside existing integrations with Amethyst, Nostur, and Nostrudel. Similarly, audio and video tools like Nostr Nests and Zap.stream will gain seamless integration into major clients, enabling easy participation in live events across the ecosystem.
Adoption and Migration: Inspired by early pioneers like Fountain and Orange Pill App, more platforms will adopt Nostr for authentication, login, and social systems. In 2025, a significant migration from a high-profile application platform with hundreds of thousands of users will transpire, doubling Nostr’s daily activity and establishing it as a cornerstone of decentralized technologies.

@ e97aaffa:2ebd765d
2024-12-31 16:47:12Último dia do ano, momento para tirar o pó da bola de cristal, para fazer reflexões, previsões e desejos para o próximo ano e seguintes.
Ano após ano, o Bitcoin evoluiu, foi ultrapassando etapas, tornou-se cada vez mais mainstream. Está cada vez mais difícil fazer previsões sobre o Bitcoin, já faltam poucas barreiras a serem ultrapassadas e as que faltam são altamente complexas ou tem um impacto profundo no sistema financeiro ou na sociedade. Estas alterações profundas tem que ser realizadas lentamente, porque uma alteração rápida poderia resultar em consequências terríveis, poderia provocar um retrocesso.
Código do Bitcoin
No final de 2025, possivelmente vamos ter um fork, as discussões sobre os covenants já estão avançadas, vão acelerar ainda mais. Já existe um consenso relativamente alto, a favor dos covenants, só falta decidir que modelo será escolhido. Penso que até ao final do ano será tudo decidido.
Depois dos covenants, o próximo foco será para a criptografia post-quantum, que será o maior desafio que o Bitcoin enfrenta. Criar uma criptografia segura e que não coloque a descentralização em causa.
Espero muito de Ark, possivelmente a inovação do ano, gostaria de ver o Nostr a furar a bolha bitcoinheira e que o Cashu tivesse mais reconhecimento pelos bitcoiners.
Espero que surjam avanços significativos no BitVM2 e BitVMX.
Não sei o que esperar das layer 2 de Bitcoin, foram a maior desilusão de 2024. Surgiram com muita força, mas pouca coisa saiu do papel, foi uma mão cheia de nada. Uma parte dos projetos caiu na tentação da shitcoinagem, na criação de tokens, que tem um único objetivo, enriquecer os devs e os VCs.
Se querem ser levados a sério, têm que ser sérios.
“À mulher de César não basta ser honesta, deve parecer honesta”
Se querem ter o apoio dos bitcoiners, sigam o ethos do Bitcoin.
Neste ponto a atitude do pessoal da Ark é exemplar, em vez de andar a chorar no Twitter para mudar o código do Bitcoin, eles colocaram as mãos na massa e criaram o protocolo. É claro que agora está meio “coxo”, funciona com uma multisig ou com os covenants na Liquid. Mas eles estão a criar um produto, vão demonstrar ao mercado que o produto é bom e útil. Com a adoção, a comunidade vai perceber que o Ark necessita dos covenants para melhorar a interoperabilidade e a soberania.
É este o pensamento certo, que deveria ser seguido pelos restantes e futuros projetos. É seguir aquele pensamento do J.F. Kennedy:
“Não perguntem o que é que o vosso país pode fazer por vocês, perguntem o que é que vocês podem fazer pelo vosso país”
Ou seja, não fiquem à espera que o bitcoin mude, criem primeiro as inovações/tecnologia, ganhem adoção e depois demonstrem que a alteração do código camada base pode melhorar ainda mais o vosso projeto. A necessidade é que vai levar a atualização do código.
Reservas Estratégicas de Bitcoin
Bancos centrais
Com a eleição de Trump, emergiu a ideia de uma Reserva Estratégia de Bitcoin, tornou este conceito mainstream. Foi um pivot, a partir desse momento, foram enumerados os políticos de todo o mundo a falar sobre o assunto.
A Senadora Cynthia Lummis foi mais além e propôs um programa para adicionar 200 mil bitcoins à reserva ao ano, até 1 milhão de Bitcoin. Só que isto está a criar uma enorme expectativa na comunidade, só que pode resultar numa enorme desilusão. Porque no primeiro ano, o Trump em vez de comprar os 200 mil, pode apenas adicionar na reserva, os 198 mil que o Estado já tem em sua posse. Se isto acontecer, possivelmente vai resultar numa forte queda a curto prazo. Na minha opinião os bancos centrais deveriam seguir o exemplo de El Salvador, fazer um DCA diário.
Mais que comprar bitcoin, para mim, o mais importante é a criação da Reserva, é colocar o Bitcoin ao mesmo nível do ouro, o impacto para o resto do mundo será tremendo, a teoria dos jogos na sua plenitude. Muitos outros bancos centrais vão ter que comprar, para não ficarem atrás, além disso, vai transmitir uma mensagem à generalidade da população, que o Bitcoin é “afinal é algo seguro, com valor”.
Mas não foi Trump que iniciou esta teoria dos jogos, mas sim foi a primeira vítima dela. É o próprio Trump que o admite, que os EUA necessitam da reserva para não ficar atrás da China. Além disso, desde que os EUA utilizaram o dólar como uma arma, com sanção contra a Rússia, surgiram boatos de que a Rússia estaria a utilizar o Bitcoin para transações internacionais. Que foram confirmados recentemente, pelo próprio governo russo. Também há poucos dias, ainda antes deste reconhecimento público, Putin elogiou o Bitcoin, ao reconhecer que “Ninguém pode proibir o bitcoin”, defendendo como uma alternativa ao dólar. A narrativa está a mudar.
Já existem alguns países com Bitcoin, mas apenas dois o fizeram conscientemente (El Salvador e Butão), os restantes têm devido a apreensões. Hoje são poucos, mas 2025 será o início de uma corrida pelos bancos centrais. Esta corrida era algo previsível, o que eu não esperava é que acontecesse tão rápido.
Empresas
A criação de reservas estratégicas não vai ficar apenas pelos bancos centrais, também vai acelerar fortemente nas empresas em 2025.
Mas as empresas não vão seguir a estratégia do Saylor, vão comprar bitcoin sem alavancagem, utilizando apenas os tesouros das empresas, como uma proteção contra a inflação. Eu não sou grande admirador do Saylor, prefiro muito mais, uma estratégia conservadora, sem qualquer alavancagem. Penso que as empresas vão seguir a sugestão da BlackRock, que aconselha um alocações de 1% a 3%.
Penso que 2025, ainda não será o ano da entrada das 6 magníficas (excepto Tesla), será sobretudo empresas de pequena e média dimensão. As magníficas ainda tem uma cota muito elevada de shareholders com alguma idade, bastante conservadores, que têm dificuldade em compreender o Bitcoin, foi o que aconteceu recentemente com a Microsoft.
Também ainda não será em 2025, talvez 2026, a inclusão nativamente de wallet Bitcoin nos sistema da Apple Pay e da Google Pay. Seria um passo gigante para a adoção a nível mundial.
ETFs
Os ETFs para mim são uma incógnita, tenho demasiadas dúvidas, como será 2025. Este ano os inflows foram superiores a 500 mil bitcoins, o IBIT foi o lançamento de ETF mais bem sucedido da história. O sucesso dos ETFs, deve-se a 2 situações que nunca mais se vão repetir. O mercado esteve 10 anos à espera pela aprovação dos ETFs, a procura estava reprimida, isso foi bem notório nos primeiros meses, os inflows foram brutais.
Também se beneficiou por ser um mercado novo, não existia orderbook de vendas, não existia um mercado interno, praticamente era só inflows. Agora o mercado já estabilizou, a maioria das transações já são entre clientes dos próprios ETFs. Agora só uma pequena percentagem do volume das transações diárias vai resultar em inflows ou outflows.
Estes dois fenómenos nunca mais se vão repetir, eu não acredito que o número de inflows em BTC supere os número de 2024, em dólares vai superar, mas em btc não acredito que vá superar.
Mas em 2025 vão surgir uma infindável quantidade de novos produtos, derivativos, novos ETFs de cestos com outras criptos ou cestos com ativos tradicionais. O bitcoin será adicionado em produtos financeiros já existentes no mercado, as pessoas vão passar a deter bitcoin, sem o saberem.
Com o fim da operação ChokePoint 2.0, vai surgir uma nova onda de adoção e de produtos financeiros. Possivelmente vamos ver bancos tradicionais a disponibilizar produtos ou serviços de custódia aos seus clientes.
Eu adoraria ver o crescimento da adoção do bitcoin como moeda, só que a regulamentação não vai ajudar nesse processo.
Preço
Eu acredito que o topo deste ciclo será alcançado no primeiro semestre, posteriormente haverá uma correção. Mas desta vez, eu acredito que a correção será muito menor que as anteriores, inferior a 50%, esta é a minha expectativa. Espero estar certo.
Stablecoins de dólar
Agora saindo um pouco do universo do Bitcoin, acho importante destacar as stablecoins.
No último ciclo, eu tenho dividido o tempo, entre continuar a estudar o Bitcoin e estudar o sistema financeiro, as suas dinâmicas e o comportamento humano. Isto tem sido o meu foco de reflexão, imaginar a transformação que o mundo vai sofrer devido ao padrão Bitcoin. É uma ilusão acreditar que a transição de um padrão FIAT para um padrão Bitcoin vai ser rápida, vai existir um processo transitório que pode demorar décadas.
Com a re-entrada de Trump na Casa Branca, prometendo uma política altamente protecionista, vai provocar uma forte valorização do dólar, consequentemente as restantes moedas do mundo vão derreter. Provocando uma inflação generalizada, gerando uma corrida às stablecoins de dólar nos países com moedas mais fracas. Trump vai ter uma política altamente expansionista, vai exportar dólares para todo o mundo, para financiar a sua própria dívida. A desigualdade entre os pobres e ricos irá crescer fortemente, aumentando a possibilidade de conflitos e revoltas.
“Casa onde não há pão, todos ralham e ninguém tem razão”
Será mais lenha, para alimentar a fogueira, vai gravar os conflitos geopolíticos já existentes, ficando as sociedade ainda mais polarizadas.
Eu acredito que 2025, vai haver um forte crescimento na adoção das stablecoins de dólares, esse forte crescimento vai agravar o problema sistémico que são as stablecoins. Vai ser o início do fim das stablecoins, pelo menos, como nós conhecemos hoje em dia.
Problema sistémico
O sistema FIAT não nasceu de um dia para outro, foi algo que foi construído organicamente, ou seja, foi evoluindo ao longo dos anos, sempre que havia um problema/crise, eram criadas novas regras ou novas instituições para minimizar os problemas. Nestes quase 100 anos, desde os acordos de Bretton Woods, a evolução foram tantas, tornaram o sistema financeiro altamente complexo, burocrático e nada eficiente.
Na prática é um castelo de cartas construído sobre outro castelo de cartas e que por sua vez, foi construído sobre outro castelo de cartas.
As stablecoins são um problema sistémico, devido às suas reservas em dólares e o sistema financeiro não está preparado para manter isso seguro. Com o crescimento das reservas ao longo dos anos, foi se agravando o problema.
No início a Tether colocava as reservas em bancos comerciais, mas com o crescimento dos dólares sob gestão, criou um problema nos bancos comerciais, devido à reserva fracionária. Essas enormes reservas da Tether estavam a colocar em risco a própria estabilidade dos bancos.
A Tether acabou por mudar de estratégia, optou por outros ativos, preferencialmente por títulos do tesouro/obrigações dos EUA. Só que a Tether continua a crescer e não dá sinais de abrandamento, pelo contrário.
Até o próprio mundo cripto, menosprezava a gravidade do problema da Tether/stablecoins para o resto do sistema financeiro, porque o marketcap do cripto ainda é muito pequeno. É verdade que ainda é pequeno, mas a Tether não o é, está no top 20 dos maiores detentores de títulos do tesouros dos EUA e está ao nível dos maiores bancos centrais do mundo. Devido ao seu tamanho, está a preocupar os responsáveis/autoridades/reguladores dos EUA, pode colocar em causa a estabilidade do sistema financeiro global, que está assente nessas obrigações.
Os títulos do tesouro dos EUA são o colateral mais utilizado no mundo, tanto por bancos centrais, como por empresas, é a charneira da estabilidade do sistema financeiro. Os títulos do tesouro são um assunto muito sensível. Na recente crise no Japão, do carry trade, o Banco Central do Japão tentou minimizar a desvalorização do iene através da venda de títulos dos EUA. Esta operação, obrigou a uma viagem de emergência, da Secretaria do Tesouro dos EUA, Janet Yellen ao Japão, onde disponibilizou liquidez para parar a venda de títulos por parte do Banco Central do Japão. Essa forte venda estava desestabilizando o mercado.
Os principais detentores de títulos do tesouros são institucionais, bancos centrais, bancos comerciais, fundo de investimento e gestoras, tudo administrado por gestores altamente qualificados, racionais e que conhecem a complexidade do mercado de obrigações.
O mundo cripto é seu oposto, é naife com muita irracionalidade e uma forte pitada de loucura, na sua maioria nem faz a mínima ideia como funciona o sistema financeiro. Essa irracionalidade pode levar a uma “corrida bancária”, como aconteceu com o UST da Luna, que em poucas horas colapsou o projeto. Em termos de escala, a Luna ainda era muito pequena, por isso, o problema ficou circunscrito ao mundo cripto e a empresas ligadas diretamente ao cripto.
Só que a Tether é muito diferente, caso exista algum FUD, que obrigue a Tether a desfazer-se de vários biliões ou dezenas de biliões de dólares em títulos num curto espaço de tempo, poderia provocar consequências terríveis em todo o sistema financeiro. A Tether é grande demais, é já um problema sistémico, que vai agravar-se com o crescimento em 2025.
Não tenham dúvidas, se existir algum problema, o Tesouro dos EUA vai impedir a venda dos títulos que a Tether tem em sua posse, para salvar o sistema financeiro. O problema é, o que vai fazer a Tether, se ficar sem acesso às venda das reservas, como fará o redeem dos dólares?
Como o crescimento do Tether é inevitável, o Tesouro e o FED estão com um grande problema em mãos, o que fazer com o Tether?
Mas o problema é que o atual sistema financeiro é como um curto cobertor: Quanto tapas a cabeça, destapas os pés; Ou quando tapas os pés, destapas a cabeça. Ou seja, para resolver o problema da guarda reservas da Tether, vai criar novos problemas, em outros locais do sistema financeiro e assim sucessivamente.
Conta mestre
Uma possível solução seria dar uma conta mestre à Tether, dando o acesso direto a uma conta no FED, semelhante à que todos os bancos comerciais têm. Com isto, a Tether deixaria de necessitar os títulos do tesouro, depositando o dinheiro diretamente no banco central. Só que isto iria criar dois novos problemas, com o Custodia Bank e com o restante sistema bancário.
O Custodia Bank luta há vários anos contra o FED, nos tribunais pelo direito a ter licença bancária para um banco com full-reserves. O FED recusou sempre esse direito, com a justificativa que esse banco, colocaria em risco toda a estabilidade do sistema bancário existente, ou seja, todos os outros bancos poderiam colapsar. Perante a existência em simultâneo de bancos com reserva fracionária e com full-reserves, as pessoas e empresas iriam optar pelo mais seguro. Isso iria provocar uma corrida bancária, levando ao colapso de todos os bancos com reserva fracionária, porque no Custodia Bank, os fundos dos clientes estão 100% garantidos, para qualquer valor. Deixaria de ser necessário limites de fundos de Garantia de Depósitos.
Eu concordo com o FED nesse ponto, que os bancos com full-reserves são uma ameaça a existência dos restantes bancos. O que eu discordo do FED, é a origem do problema, o problema não está nos bancos full-reserves, mas sim nos que têm reserva fracionária.
O FED ao conceder uma conta mestre ao Tether, abre um precedente, o Custodia Bank irá o aproveitar, reclamando pela igualdade de direitos nos tribunais e desta vez, possivelmente ganhará a sua licença.
Ainda há um segundo problema, com os restantes bancos comerciais. A Tether passaria a ter direitos similares aos bancos comerciais, mas os deveres seriam muito diferentes. Isto levaria os bancos comerciais aos tribunais para exigir igualdade de tratamento, é uma concorrência desleal. Isto é o bom dos tribunais dos EUA, são independentes e funcionam, mesmo contra o estado. Os bancos comerciais têm custos exorbitantes devido às políticas de compliance, como o KYC e AML. Como o governo não vai querer aliviar as regras, logo seria a Tether, a ser obrigada a fazer o compliance dos seus clientes.
A obrigação do KYC para ter stablecoins iriam provocar um terramoto no mundo cripto.
Assim, é pouco provável que seja a solução para a Tether.
FED
Só resta uma hipótese, ser o próprio FED a controlar e a gerir diretamente as stablecoins de dólar, nacionalizado ou absorvendo as existentes. Seria uma espécie de CBDC. Isto iria provocar um novo problema, um problema diplomático, porque as stablecoins estão a colocar em causa a soberania monetária dos outros países. Atualmente as stablecoins estão um pouco protegidas porque vivem num limbo jurídico, mas a partir do momento que estas são controladas pelo governo americano, tudo muda. Os países vão exigir às autoridades americanas medidas que limitem o uso nos seus respectivos países.
Não existe uma solução boa, o sistema FIAT é um castelo de cartas, qualquer carta que se mova, vai provocar um desmoronamento noutro local. As autoridades não poderão adiar mais o problema, terão que o resolver de vez, senão, qualquer dia será tarde demais. Se houver algum problema, vão colocar a responsabilidade no cripto e no Bitcoin. Mas a verdade, a culpa é inteiramente dos políticos, da sua incompetência em resolver os problemas a tempo.
Será algo para acompanhar futuramente, mas só para 2026, talvez…
É curioso, há uns anos pensava-se que o Bitcoin seria a maior ameaça ao sistema ao FIAT, mas afinal, a maior ameaça aos sistema FIAT é o próprio FIAT(stablecoins). A ironia do destino.
Isto é como uma corrida, o Bitcoin é aquele atleta que corre ao seu ritmo, umas vezes mais rápido, outras vezes mais lento, mas nunca pára. O FIAT é o atleta que dá tudo desde da partida, corre sempre em velocidade máxima. Só que a vida e o sistema financeiro não é uma prova de 100 metros, mas sim uma maratona.
Europa
2025 será um ano desafiante para todos europeus, sobretudo devido à entrada em vigor da regulamentação (MiCA). Vão começar a sentir na pele a regulamentação, vão agravar-se os problemas com os compliance, problemas para comprovar a origem de fundos e outras burocracias. Vai ser lindo.
O Travel Route passa a ser obrigatório, os europeus serão obrigados a fazer o KYC nas transações. A Travel Route é uma suposta lei para criar mais transparência, mas prática, é uma lei de controle, de monitorização e para limitar as liberdades individuais dos cidadãos.
O MiCA também está a colocar problemas nas stablecoins de Euro, a Tether para já preferiu ficar de fora da europa. O mais ridículo é que as novas regras obrigam os emissores a colocar 30% das reservas em bancos comerciais. Os burocratas europeus não compreendem que isto coloca em risco a estabilidade e a solvência dos próprios bancos, ficam propensos a corridas bancárias.
O MiCA vai obrigar a todas as exchanges a estar registadas em solo europeu, ficando vulnerável ao temperamento dos burocratas. Ainda não vai ser em 2025, mas a UE vai impor políticas de controle de capitais, é inevitável, as exchanges serão obrigadas a usar em exclusividade stablecoins de euro, as restantes stablecoins serão deslistadas.
Todas estas novas regras do MiCA, são extremamente restritas, não é para garantir mais segurança aos cidadãos europeus, mas sim para garantir mais controle sobre a população. A UE está cada vez mais perto da autocracia, do que da democracia. A minha única esperança no horizonte, é que o sucesso das políticas cripto nos EUA, vai obrigar a UE a recuar e a aligeirar as regras, a teoria dos jogos é implacável. Mas esse recuo, nunca acontecerá em 2025, vai ser um longo período conturbado.
Recessão
Os mercados estão todos em máximos históricos, isto não é sustentável por muito tempo, suspeito que no final de 2025 vai acontecer alguma correção nos mercados. A queda só não será maior, porque os bancos centrais vão imprimir dinheiro, muito dinheiro, como se não houvesse amanhã. Vão voltar a resolver os problemas com a injeção de liquidez na economia, é empurrar os problemas com a barriga, em de os resolver. Outra vez o efeito Cantillon.
Será um ano muito desafiante a nível político, onde o papel dos políticos será fundamental. A crise política na França e na Alemanha, coloca a UE órfã, sem um comandante ao leme do navio. 2025 estará condicionado pelas eleições na Alemanha, sobretudo no resultado do AfD, que podem colocar em causa a propriedade UE e o euro.
Possivelmente, só o fim da guerra poderia minimizar a crise, algo que é muito pouco provável acontecer.
Em Portugal, a economia parece que está mais ou menos equilibrada, mas começam a aparecer alguns sinais preocupantes. Os jogos de sorte e azar estão em máximos históricos, batendo o recorde de 2014, época da grande crise, não é um bom sinal, possivelmente já existe algum desespero no ar.
A Alemanha é o motor da Europa, quanto espirra, Portugal constipa-se. Além do problema da Alemanha, a Espanha também está à beira de uma crise, são os países que mais influenciam a economia portuguesa.
Se existir uma recessão mundial, terá um forte impacto no turismo, que é hoje em dia o principal motor de Portugal.
Brasil
Brasil é algo para acompanhar em 2025, sobretudo a nível macro e a nível político. Existe uma possibilidade de uma profunda crise no Brasil, sobretudo na sua moeda. O banco central já anda a queimar as reservas para minimizar a desvalorização do Real.
Sem mudanças profundas nas políticas fiscais, as reservas vão se esgotar. As políticas de controle de capitais são um cenário plausível, será interesse de acompanhar, como o governo irá proceder perante a existência do Bitcoin e stablecoins. No Brasil existe um forte adoção, será um bom case study, certamente irá repetir-se em outros países num futuro próximo.
Os próximos tempos não serão fáceis para os brasileiros, especialmente para os que não têm Bitcoin.
Blockchain
Em 2025, possivelmente vamos ver os primeiros passos da BlackRock para criar a primeira bolsa de valores, exclusivamente em blockchain. Eu acredito que a BlackRock vai criar uma própria blockchain, toda controlada por si, onde estarão os RWAs, para fazer concorrência às tradicionais bolsas de valores. Será algo interessante de acompanhar.
Estas são as minhas previsões, eu escrevi isto muito em cima do joelho, certamente esqueci-me de algumas coisas, se for importante acrescentarei nos comentários. A maioria das previsões só acontecerá após 2025, mas fica aqui a minha opinião.
Isto é apenas a minha opinião, Don’t Trust, Verify!

2025-03-01 23:24:35CSS Fundamentals: Styling Your First Webpage
Introduction
In our previous lesson, we created the structure of our webpage with HTML. Now, we'll learn how to style it using CSS (Cascading Style Sheets). While HTML provides the bones of our webpage, CSS adds the visual presentation - the colors, layouts, spacing, and overall aesthetics.
What is CSS?
Definition
CSS (Cascading Style Sheets) is a stylesheet language that controls the visual presentation of HTML documents. Think of it like the paint, decorations, and interior design of a house - it determines how everything looks and is arranged.
Key Concepts
- Styling Capabilities
- Fonts and typography
- Colors and backgrounds
- Margins and padding
- Element sizes
- Visual effects
-
Layout and positioning
-
Cascading Nature
- Styles can be inherited from parent elements
- Multiple styles can apply to the same element
- Specificity determines which styles take precedence
- Styles "cascade" down through your document
Basic CSS Syntax
css selector { property: value; }
Example:
css h1 { color: blue; font-size: 24px; margin-bottom: 20px; }
Connecting CSS to HTML
Method 1: External Stylesheet (Recommended)
html <link rel="stylesheet" href="style.css">
Method 2: Internal CSS
```html
```
Method 3: Inline CSS (Use Sparingly)
```html
Title
```
The Box Model
Every HTML element is treated as a box in CSS, with:
┌──────────────────────┐ │ Margin │ │ ┌──────────────┐ │ │ │ Border │ │ │ │ ┌──────────┐ │ │ │ │ │ Padding │ │ │ │ │ │ ┌──────┐ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │Content│ │ │ │ │ │ │ │ │ │ │ │ │ │ │ └──────┘ │ │ │ │ │ └──────────┘ │ │ │ └──────────────┘ │ └──────────────────────┘
- Content: The actual content of the element
- Padding: Space between content and border
- Border: The border around the padding
- Margin: Space outside the border
CSS Units
Absolute Units
px
- pixelspt
- pointscm
- centimetersmm
- millimetersin
- inches
Relative Units
%
- percentage relative to parentem
- relative to font-sizerem
- relative to root font-sizevh
- viewport heightvw
- viewport width
Practical Example: Styling Our Webpage
1. Basic Page Setup
css body { min-height: 100vh; margin: 0; font-family: Arial, sans-serif; background-color: #f0f0f0; display: flex; flex-direction: column; }
2. Header Styling
css header { background-color: #333; color: white; padding: 20px; text-align: center; }
3. Main Content Area
css main { max-width: 800px; margin: 0 auto; padding: 20px; flex: 1; }
4. Footer Styling
css footer { background-color: #333; color: white; padding: 10px; text-align: center; }
Layout with Flexbox
Basic Concept
Flexbox is a modern layout system that makes it easier to create flexible, responsive layouts.
Key Properties
css .container { display: flex; flex-direction: row | column; justify-content: center | space-between | space-around; align-items: center | flex-start | flex-end; }
Common Use Cases
- Centering content
- Creating navigation bars
- Building responsive layouts
- Equal-height columns
- Dynamic spacing
Best Practices
1. Organization
- Use consistent naming conventions
- Group related styles together
- Comment your code for clarity
- Keep selectors simple and specific
2. Performance
- Avoid unnecessary specificity
- Use shorthand properties when possible
- Minimize redundant code
- Consider load time impact
3. Maintainability
- Use external stylesheets
- Follow a consistent formatting style
- Break large stylesheets into logical files
- Document important design decisions
Debugging CSS
Common Tools
- Browser Developer Tools
- Element inspector
- Style inspector
- Box model viewer
Common Issues
- Specificity conflicts
- Inheritance problems
- Box model confusion
- Flexbox alignment issues
Exercises
1. Style Modifications
Try modifying these properties in your stylesheet: ```css / Change colors / header { background-color: #4a90e2; }
/ Adjust spacing / main { padding: 40px; }
/ Modify typography / h1 { font-size: 32px; font-weight: bold; } ```
2. Layout Challenge
Create a card layout using Flexbox: ```css .card-container { display: flex; justify-content: space-between; gap: 20px; }
.card { flex: 1; padding: 20px; background: white; border-radius: 8px; box-shadow: 0 2px 4px rgba(0,0,0,0.1); } ```
Additional Resources
Learning Tools
- Flexbox Froggy - Interactive Flexbox learning game
- CSS-Tricks - Excellent CSS reference and tutorials
- MDN CSS Documentation
Practice Projects
- Style your personal webpage
- Create a responsive navigation menu
- Build a flexible card layout
- Design a custom button style
Remember: CSS is both an art and a science. Don't be afraid to experiment and break things - that's how you'll learn the most. The key is to start simple and gradually add complexity as you become more comfortable with the basics.
Next up, we'll dive into JavaScript to add interactivity to our webpage! 🚀

2025-01-13 10:09:57Ich begann, Social Media aufzubauen, \ um den Menschen eine Stimme zu geben. \ Mark Zuckerberg
Sind euch auch die Tränen gekommen, als ihr Mark Zuckerbergs Wendehals-Deklaration bezüglich der Meinungsfreiheit auf seinen Portalen gehört habt? Rührend, oder? Während er früher die offensichtliche Zensur leugnete und später die Regierung Biden dafür verantwortlich machte, will er nun angeblich «die Zensur auf unseren Plattformen drastisch reduzieren».
«Purer Opportunismus» ob des anstehenden Regierungswechsels wäre als Klassifizierung viel zu kurz gegriffen. Der jetzige Schachzug des Meta-Chefs ist genauso Teil einer kühl kalkulierten Business-Strategie, wie es die 180 Grad umgekehrte Praxis vorher war. Social Media sind ein höchst lukratives Geschäft. Hinzu kommt vielleicht noch ein bisschen verkorkstes Ego, weil derartig viel Einfluss und Geld sicher auch auf die Psyche schlagen. Verständlich.
«Es ist an der Zeit, zu unseren Wurzeln der freien Meinungsäußerung auf Facebook und Instagram zurückzukehren. Ich begann, Social Media aufzubauen, um den Menschen eine Stimme zu geben», sagte Zuckerberg.
Welche Wurzeln? Hat der Mann vergessen, dass er von der Überwachung, dem Ausspionieren und dem Ausverkauf sämtlicher Daten und digitaler Spuren sowie der Manipulation seiner «Kunden» lebt? Das ist knallharter Kommerz, nichts anderes. Um freie Meinungsäußerung geht es bei diesem Geschäft ganz sicher nicht, und das war auch noch nie so. Die Wurzeln von Facebook liegen in einem Projekt des US-Militärs mit dem Namen «LifeLog». Dessen Ziel war es, «ein digitales Protokoll vom Leben eines Menschen zu erstellen».
Der Richtungswechsel kommt allerdings nicht überraschend. Schon Anfang Dezember hatte Meta-Präsident Nick Clegg von «zu hoher Fehlerquote bei der Moderation» von Inhalten gesprochen. Bei der Gelegenheit erwähnte er auch, dass Mark sehr daran interessiert sei, eine aktive Rolle in den Debatten über eine amerikanische Führungsrolle im technologischen Bereich zu spielen.
Während Milliardärskollege und Big Tech-Konkurrent Elon Musk bereits seinen Posten in der kommenden Trump-Regierung in Aussicht hat, möchte Zuckerberg also nicht nur seine Haut retten – Trump hatte ihn einmal einen «Feind des Volkes» genannt und ihm lebenslange Haft angedroht –, sondern am liebsten auch mitspielen. KI-Berater ist wohl die gewünschte Funktion, wie man nach einem Treffen Trump-Zuckerberg hörte. An seine Verhaftung dachte vermutlich auch ein weiterer Multimilliardär mit eigener Social Media-Plattform, Pavel Durov, als er Zuckerberg jetzt kritisierte und gleichzeitig warnte.
Politik und Systemmedien drehen jedenfalls durch – was zu viel ist, ist zu viel. Etwas weniger Zensur und mehr Meinungsfreiheit würden die Freiheit der Bürger schwächen und seien potenziell vernichtend für die Menschenrechte. Zuckerberg setze mit dem neuen Kurs die Demokratie aufs Spiel, das sei eine «Einladung zum nächsten Völkermord», ernsthaft. Die Frage sei, ob sich die EU gegen Musk und Zuckerberg behaupten könne, Brüssel müsse jedenfalls hart durchgreifen.
Auch um die Faktenchecker macht man sich Sorgen. Für die deutsche Nachrichtenagentur dpa und die «Experten» von Correctiv, die (noch) Partner für Fact-Checking-Aktivitäten von Facebook sind, sei das ein «lukratives Geschäftsmodell». Aber möglicherweise werden die Inhalte ohne diese vermeintlichen Korrektoren ja sogar besser. Anders als Meta wollen jedoch Scholz, Faeser und die Tagesschau keine Fehler zugeben und zum Beispiel Correctiv-Falschaussagen einräumen.
Bei derlei dramatischen Befürchtungen wundert es nicht, dass der öffentliche Plausch auf X zwischen Elon Musk und AfD-Chefin Alice Weidel von 150 EU-Beamten überwacht wurde, falls es irgendwelche Rechtsverstöße geben sollte, die man ihnen ankreiden könnte. Auch der Deutsche Bundestag war wachsam. Gefunden haben dürften sie nichts. Das Ganze war eher eine Show, viel Wind wurde gemacht, aber letztlich gab es nichts als heiße Luft.
Das Anbiedern bei Donald Trump ist indes gerade in Mode. Die Weltgesundheitsorganisation (WHO) tut das auch, denn sie fürchtet um Spenden von über einer Milliarde Dollar. Eventuell könnte ja Elon Musk auch hier künftig aushelfen und der Organisation sowie deren größtem privaten Förderer, Bill Gates, etwas unter die Arme greifen. Nachdem Musks KI-Projekt xAI kürzlich von BlackRock & Co. sechs Milliarden eingestrichen hat, geht da vielleicht etwas.

2025-01-03 20:26:47Was du bist hängt von drei Faktoren ab: \ Was du geerbt hast, \ was deine Umgebung aus dir machte \ und was du in freier Wahl \ aus deiner Umgebung und deinem Erbe gemacht hast. \ Aldous Huxley
Das brave Mitmachen und Mitlaufen in einem vorgegebenen, recht engen Rahmen ist gewiss nicht neu, hat aber gerade wieder mal Konjunktur. Dies kann man deutlich beobachten, eigentlich egal, in welchem gesellschaftlichen Bereich man sich umschaut. Individualität ist nur soweit angesagt, wie sie in ein bestimmtes Schema von «Diversität» passt, und Freiheit verkommt zur Worthülse – nicht erst durch ein gewisses Buch einer gewissen ehemaligen Regierungschefin.
Erklärungsansätze für solche Entwicklungen sind bekannt, und praktisch alle haben etwas mit Massenpsychologie zu tun. Der Herdentrieb, also der Trieb der Menschen, sich – zum Beispiel aus Unsicherheit oder Bequemlichkeit – lieber der Masse anzuschließen als selbstständig zu denken und zu handeln, ist einer der Erklärungsversuche. Andere drehen sich um Macht, Propaganda, Druck und Angst, also den gezielten Einsatz psychologischer Herrschaftsinstrumente.
Aber wollen die Menschen überhaupt Freiheit? Durch Gespräche im privaten Umfeld bin ich diesbezüglich in der letzten Zeit etwas skeptisch geworden. Um die Jahreswende philosophiert man ja gerne ein wenig über das Erlebte und über die Erwartungen für die Zukunft. Dabei hatte ich hin und wieder den Eindruck, die totalitären Anwandlungen unserer «Repräsentanten» kämen manchen Leuten gerade recht.
«Desinformation» ist so ein brisantes Thema. Davor müsse man die Menschen doch schützen, hörte ich. Jemand müsse doch zum Beispiel diese ganzen merkwürdigen Inhalte in den Social Media filtern – zur Ukraine, zum Klima, zu Gesundheitsthemen oder zur Migration. Viele wüssten ja gar nicht einzuschätzen, was richtig und was falsch ist, sie bräuchten eine Führung.
Freiheit bedingt Eigenverantwortung, ohne Zweifel. Eventuell ist es einigen tatsächlich zu anspruchsvoll, die Verantwortung für das eigene Tun und Lassen zu übernehmen. Oder die persönliche Freiheit wird nicht als ausreichend wertvolles Gut angesehen, um sich dafür anzustrengen. In dem Fall wäre die mangelnde Selbstbestimmung wohl das kleinere Übel. Allerdings fehlt dann gemäß Aldous Huxley ein Teil der Persönlichkeit. Letztlich ist natürlich alles eine Frage der Abwägung.
Sind viele Menschen möglicherweise schon so «eingenordet», dass freiheitliche Ambitionen gar nicht für eine ganze Gruppe, ein Kollektiv, verfolgt werden können? Solche Gedanken kamen mir auch, als ich mir kürzlich diverse Talks beim viertägigen Hacker-Kongress des Chaos Computer Clubs (38C3) anschaute. Ich war nicht nur überrascht, sondern reichlich erschreckt angesichts der in weiten Teilen mainstream-geformten Inhalte, mit denen ein dankbares Publikum beglückt wurde. Wo ich allgemein hellere Köpfe erwartet hatte, fand ich Konformismus und enthusiastisch untermauerte Narrative.
Gibt es vielleicht so etwas wie eine Herdenimmunität gegen Indoktrination? Ich denke, ja, zumindest eine gestärkte Widerstandsfähigkeit. Was wir brauchen, sind etwas gesunder Menschenverstand, offene Informationskanäle und der Mut, sich freier auch zwischen den Herden zu bewegen. Sie tun das bereits, aber sagen Sie es auch dieses Jahr ruhig weiter.

2024-12-30 19:02:32Na era das grandes navegações, piratas ingleses eram autorizados pelo governo para roubar navios.
A única coisa que diferenciava um pirata comum de um corsário é que o último possuía a “Carta do Corso”, que funcionava como um “Alvará para o roubo”, onde o governo Inglês legitimava o roubo de navios por parte dos corsários. É claro, que em troca ele exigia uma parte da espoliação.
Bastante similar com a maneira que a Receita Federal atua, não? Na verdade, o caso é ainda pior, pois o governo fica com toda a riqueza espoliada, e apenas repassa um mísero salário para os corsários modernos, os agentes da receita federal.
Porém eles “justificam” esse roubo ao chamá-lo de imposto, e isso parece acalmar os ânimos de grande parte da população, mas não de nós. Não é por acaso que 'imposto' é o particípio passado do verbo 'impor'. Ou seja, é aquilo que resulta do cumprimento obrigatório -- e não voluntário -- de todos os cidadãos. Se não for 'imposto' ninguém paga. Nem mesmo seus defensores. Isso mostra o quanto as pessoas realmente apreciam os serviços do estado.
Apenas volte um pouco na história: os primeiros pagadores de impostos eram fazendeiros cujos territórios foram invadidos por nômades que pastoreavam seu gado. Esses invasores nômades forçavam os fazendeiros a lhes pagar uma fatia de sua renda em troca de "proteção". O fazendeiro que não concordasse era assassinado.
Os nômades perceberam que era muito mais interessante e confortável apenas cobrar uma taxa de proteção em vez de matar o fazendeiro e assumir suas posses. Cobrando uma taxa, eles obtinham o que necessitavam. Já se matassem os fazendeiros, eles teriam de gerenciar por conta própria toda a produção da fazenda. Daí eles entenderam que, ao não assassinarem todos os fazendeiros que encontrassem pelo caminho, poderiam fazer desta prática um modo de vida.
Assim nasceu o governo.
Não assassinar pessoas foi o primeiro serviço que o governo forneceu. Como temos sorte em ter à nossa disposição esta instituição!
Assim, não deixa de ser curioso que algumas pessoas digam que os impostos são pagos basicamente para impedir que aconteça exatamente aquilo que originou a existência do governo. O governo nasceu da extorsão. Os fazendeiros tinham de pagar um "arrego" para seu governo. Caso contrário, eram assassinados. Quem era a real ameaça? O governo. A máfia faz a mesma coisa.
Mas existe uma forma de se proteger desses corsários modernos. Atualmente, existe uma propriedade privada que NINGUÉM pode tirar de você, ela é sua até mesmo depois da morte. É claro que estamos falando do Bitcoin. Fazendo as configurações certas, é impossível saber que você tem bitcoin. Nem mesmo o governo americano consegue saber.

2024-12-23 16:47:01At the intersection of philosophy, theology, physics, biology, and finance lies a terrifying truth: the fiat monetary system, in its current form, is not just an economic framework but a silent, relentless force actively working against humanity's survival. It isn't simply a failed financial model—it is a systemic engine of destruction, both externally and within the very core of our biological existence.
The Philosophical Void of Fiat
Philosophy has long questioned the nature of value and the meaning of human existence. From Socrates to Kant, thinkers have pondered the pursuit of truth, beauty, and virtue. But in the modern age, the fiat system has hijacked this discourse. The notion of "value" in a fiat world is no longer rooted in human potential or natural resources—it is abstracted, manipulated, and controlled by central authorities with the sole purpose of perpetuating their own power. The currency is not a reflection of society’s labor or resources; it is a representation of faith in an authority that, more often than not, breaks that faith with reckless monetary policies and hidden inflation.
The fiat system has created a kind of ontological nihilism, where the idea of true value, rooted in work, creativity, and family, is replaced with speculative gambling and short-term gains. This betrayal of human purpose at the systemic level feeds into a philosophical despair: the relentless devaluation of effort, the erosion of trust, and the abandonment of shared human values. In this nihilistic economy, purpose and meaning become increasingly difficult to find, leaving millions to question the very foundation of their existence.
Theological Implications: Fiat and the Collapse of the Sacred
Religious traditions have long linked moral integrity with the stewardship of resources and the preservation of life. Fiat currency, however, corrupts these foundational beliefs. In the theological narrative of creation, humans are given dominion over the Earth, tasked with nurturing and protecting it for future generations. But the fiat system promotes the exact opposite: it commodifies everything—land, labor, and life—treating them as mere transactions on a ledger.
This disrespect for creation is an affront to the divine. In many theologies, creation is meant to be sustained, a delicate balance that mirrors the harmony of the divine order. Fiat systems—by continuously printing money and driving inflation—treat nature and humanity as expendable resources to be exploited for short-term gains, leading to environmental degradation and societal collapse. The creation narrative, in which humans are called to be stewards, is inverted. The fiat system, through its unholy alliance with unrestrained growth and unsustainable debt, is destroying the very creation it should protect.
Furthermore, the fiat system drives idolatry of power and wealth. The central banks and corporations that control the money supply have become modern-day gods, their decrees shaping the lives of billions, while the masses are enslaved by debt and inflation. This form of worship isn't overt, but it is profound. It leads to a world where people place their faith not in God or their families, but in the abstract promises of institutions that serve their own interests.
Physics and the Infinite Growth Paradox
Physics teaches us that the universe is finite—resources, energy, and space are all limited. Yet, the fiat system operates under the delusion of infinite growth. Central banks print money without concern for natural limits, encouraging an economy that assumes unending expansion. This is not only an economic fallacy; it is a physical impossibility.
In thermodynamics, the Second Law states that entropy (disorder) increases over time in any closed system. The fiat system operates as if the Earth were an infinite resource pool, perpetually able to expand without consequence. The real world, however, does not bend to these abstract concepts of infinite growth. Resources are finite, ecosystems are fragile, and human capacity is limited. Fiat currency, by promoting unsustainable consumption and growth, accelerates the depletion of resources and the degradation of natural systems that support life itself.
Even the financial “growth” driven by fiat policies leads to unsustainable bubbles—inflated stock markets, real estate, and speculative assets that burst and leave ruin in their wake. These crashes aren’t just economic—they have profound biological consequences. The cycles of boom and bust undermine communities, erode social stability, and increase anxiety and depression, all of which affect human health at a biological level.
Biology: The Fiat System and the Destruction of Human Health
Biologically, the fiat system is a cancerous growth on human society. The constant chase for growth and the devaluation of work leads to chronic stress, which is one of the leading causes of disease in modern society. The strain of living in a system that values speculation over well-being results in a biological feedback loop: rising anxiety, poor mental health, physical diseases like cardiovascular disorders, and a shortening of lifespans.
Moreover, the focus on profit and short-term returns creates a biological disconnect between humans and the planet. The fiat system fuels industries that destroy ecosystems, increase pollution, and deplete resources at unsustainable rates. These actions are not just environmentally harmful; they directly harm human biology. The degradation of the environment—whether through toxic chemicals, pollution, or resource extraction—has profound biological effects on human health, causing respiratory diseases, cancers, and neurological disorders.
The biological cost of the fiat system is not a distant theory; it is being paid every day by millions in the form of increased health risks, diseases linked to stress, and the growing burden of mental health disorders. The constant uncertainty of an inflation-driven economy exacerbates these conditions, creating a society of individuals whose bodies and minds are under constant strain. We are witnessing a systemic biological unraveling, one in which the very act of living is increasingly fraught with pain, instability, and the looming threat of collapse.
Finance as the Final Illusion
At the core of the fiat system is a fundamental illusion—that financial growth can occur without any real connection to tangible value. The abstraction of currency, the manipulation of interest rates, and the constant creation of new money hide the underlying truth: the system is built on nothing but faith. When that faith falters, the entire system collapses.
This illusion has become so deeply embedded that it now defines the human experience. Work no longer connects to production or creation—it is reduced to a transaction on a spreadsheet, a means to acquire more fiat currency in a world where value is ephemeral and increasingly disconnected from human reality.
As we pursue ever-expanding wealth, the fundamental truths of biology—interdependence, sustainability, and balance—are ignored. The fiat system’s abstract financial models serve to disconnect us from the basic realities of life: that we are part of an interconnected world where every action has a reaction, where resources are finite, and where human health, both mental and physical, depends on the stability of our environment and our social systems.
The Ultimate Extermination
In the end, the fiat system is not just an economic issue; it is a biological, philosophical, theological, and existential threat to the very survival of humanity. It is a force that devalues human effort, encourages environmental destruction, fosters inequality, and creates pain at the core of the human biological condition. It is an economic framework that leads not to prosperity, but to extermination—not just of species, but of the very essence of human well-being.
To continue on this path is to accept the slow death of our species, one based not on natural forces, but on our own choice to worship the abstract over the real, the speculative over the tangible. The fiat system isn't just a threat; it is the ultimate self-inflicted wound, a cultural and financial cancer that, if left unchecked, will destroy humanity’s chance for survival and peace.

2025-03-01 23:23:54JavaScript: Building Your First Interactive Web App
Introduction
In this lesson, we'll bring our web pages to life by adding dynamic functionality with JavaScript. We'll build a real-world application that displays and updates Bitcoin prices in real-time, teaching core JavaScript concepts along the way.
Project Overview: Bitcoin Price Tracker
We'll build a web application that: - Displays current Bitcoin price - Updates automatically every 3 seconds - Allows currency switching - Includes interactive controls - Shows current date/time
Core JavaScript Concepts
1. Variables and Data Types
```javascript // Variables can be declared with let or const let currentCurrency = "USD"; // Can be changed const interval = 3000; // Cannot be changed
// Basic data types const price = 45000; // Number const isVisible = true; // Boolean const currency = "USD"; // String ```
2. DOM Manipulation
```javascript // Getting elements const priceElement = document.getElementById('price'); const button = document.getElementById('refresh-button');
// Modifying content priceElement.textContent =
${price} ${currency}
;// Changing styles priceElement.style.display = 'none'; ```
3. Event Listeners
```javascript // Basic click handler button.addEventListener('click', () => { fetchBitcoinPrice(); });
// Change event for select elements selector.addEventListener('change', (event) => { handleCurrencyChange(event.value); }); ```
4. Async Operations & Fetch API
javascript async function fetchBitcoinPrice() { try { const response = await fetch(apiUrl); const data = await response.json(); updatePrice(data.price); } catch (error) { console.error('Error:', error); } }
Project Structure
HTML Setup
```html
Bitcoin Price Tracker Current Bitcoin Price
The price is:
```
Core Functionality Implementation
- Setting Up the Timer ```javascript // Update price every 3 seconds setInterval(fetchBitcoinPrice, 3000);
// Update date/time every second setInterval(updateDateTime, 1000); ```
-
Currency Selection
javascript function handleCurrencyChange(newCurrency) { currentCurrency = newCurrency; fetchBitcoinPrice(); }
-
Toggle Visibility
javascript function togglePriceVisibility() { const price = document.getElementById('price'); price.style.display = price.style.display === 'none' ? 'inline' : 'none'; }
Best Practices

2025-03-06 15:37:04Os óleos essenciais são os principais ativos terapêuticos da Aromaterapia. No entanto, assim como qualquer substância que aplicamos na pele, inalamos ou ingerimos, eles podem causar reações alérgicas. Esse risco é ainda maior porque os óleos essenciais contêm compostos altamente concentrados, alguns dos quais possuem grande potencial alergênico. Por isso, é fundamental conhecer bem os óleos essenciais e entender seus riscos antes de utilizá-los.
Entendendo os riscos dos óleos essenciais
Embora sejam naturais, os óleos essenciais são altamente concentrados e podem provocar irritações ou alergias em algumas pessoas. Cada óleo contém diferentes componentes químicos, e é essencial compreender sua toxicidade para um uso seguro.
Podemos dividir os principais componentes químicos dos óleos essenciais em dois grandes grupos:
- Aromáticos ou fenóis
- Terpênicos
Além desses, existem outras substâncias que, apesar de terem propriedades terapêuticas, também podem apresentar riscos, como: lactonas, cumarinas (responsáveis pela fototoxicidade), ftalidas, compostos nitrogenados e compostos sulfurados.
A toxicidade de um óleo essencial depende da concentração dessas substâncias e do método de extração. Por exemplo, óleos obtidos pelo método de prensagem a frio preservam melhor seus componentes químicos, tornando-se mais potentes terapeuticamente, mas também mais propensos a causar reações adversas.
Os principais riscos dos óleos essenciais incluem:
✔️ Fotossensibilização (aumenta a sensibilidade da pele ao sol) ✔️ Efeito cáustico (pode causar queimaduras químicas) ✔️ Irritação na pele e nas mucosas ✔️ Reações alérgicas ✔️ Nefrotoxicidade (toxicidade para os rins) ✔️ Hepatotoxicidade (toxicidade para o fígado) ✔️ Neurotoxicidade (efeitos no sistema nervoso)
Diante desses riscos, é essencial contar com a orientação de um profissional e sempre realizar um teste de sensibilidade antes de usar qualquer óleo essencial.
Como fazer o teste de sensibilidade?
O teste de sensibilidade deve ser feito em áreas mais sensíveis da pele, como a dobra do cotovelo ou atrás da orelha – sendo a dobra do cotovelo a opção mais segura.
Passo a passo: Diluir o óleo essencial: misture 1 ou 2 gotas do óleo essencial em 5 mL de óleo carreador (ou siga a proporção de 1 gota de óleo essencial para 5 gotas de carreador). Aplicar na pele: passe a mistura na região escolhida. Observar por 24 horas: caso surjam vermelhidão, coceira ou irritação, é importante avaliar a gravidade da reação com um profissional antes de prosseguir com o uso. Mesmo em casos de reações leves, pode ser possível utilizar o óleo essencial com uma diluição maior. Nesses casos, o aromaterapeuta pode ajustar a formulação conforme tabelas específicas para pessoas sensíveis.
Dicas para um uso seguro dos óleos essenciais
✅ Nunca use óleos essenciais puros na pele. Sempre dilua em um óleo carreador adequado, pois ele transporta os ativos sem alterar suas propriedades e pode até potencializar os efeitos terapêuticos. ✅ Atenção à inalação! Ajuste o número de gotas no difusor e o tempo de exposição. No início do tratamento, prefira difusões curtas (até 30 minutos). ✅ Atenção às diluições! As proporções variam conforme o público:
Crianças e pessoas sensíveis: diluição máxima de 1% de óleo essencial na fórmula. Adultos saudáveis: diluição entre 2% e 3%.
Se você tem dúvidas ou quer saber como a Aromaterapia pode ajudar no seu dia a dia, me mande uma mensagem! Será um prazer te ajudar a usar os óleos essenciais com segurança. 😊✨

2025-03-06 15:33:35In today's world, most running apps function just like Facebook—they track your runs, collect your personal data, and monetize your activity by selling insights to third parties. You are the product. But what if there was a way to track your running stats without sacrificing your privacy? Enter Runstr, the first running app built on the Nostr protocol.
A Running App That Respects Your Privacy
Unlike traditional fitness apps that harvest your data, Runstr leverages Nostr, a decentralized protocol that ensures your running stats remain under your control. This means you can log your runs, measure your performance, and improve your fitness without exposing your data to corporations, advertisers, or big tech.
From PWA to Android: Improving the Experience
We started with a Progressive Web App (PWA) as a proof of concept. However, we quickly ran into challenges with tracking run stats when the screen was turned off. To overcome these limitations, we pivoted to building a dedicated Android app that allows for better functionality and seamless background tracking. The response has been great so far, with early adopters loving the enhanced features and user experience.
Features & Integrations
Runstr is designed to be a powerful, yet lightweight running companion. Some of the key features include:
- Accurate run tracking: Distance, time, pace, and more
- Wavlake integration: Listen to your favorite tracks while running without switching apps
- Zero data harvesting: No third-party tracking, no selling your information
Recognition & Roadmap
We recently presented Runstr to PlebLab, and they loved the concept! They’ve offered mentorship and promotion support to help us scale. Looking ahead, here’s what’s coming in the next quarter:
- Running events & team events
- Personal goals & performance tracking
- Advanced statistics dashboard
- Local running clubs
- Runstr branding strategy for the app & running merchandise
Additionally, Runstr LLC is now an official business entity, marking a major milestone in our journey.
Nosfabrica - SALUD Decentralized Health App Development Challenge
We’ve entered the Nosfabrica - SALUD Decentralized Health App Development Challenge, whose mission is to develop an ecosystem of open-source tools built on Nostr and Bitcoin to decentralize healthcare, improve health, and address challenges in healthcare access, data portability, and overall health outcomes. Currently, the total prize pool is 0.12 BTC, and all participating projects can be found on the Kanbanstr board.
Fundraising & How You Can Support
To accelerate our development and bring Runstr to the next level, we are raising 0.1 BTC to fund design, branding, and development. Our goal is to launch the official Runstr app on zap.store by the end of May.
If you’d like to support this vision, you can:
- Download the app, take it for a run, and share your feedback on Nostr using the hashtag #runstr.
- Contribute to our fundraising via Geyser Fund.
Together, we can build the ultimate privacy-first running app. Join us and let’s run free! 🏃♂️⚡

2024-12-22 21:35:22I’ll admit that I was wrong about Bitcoin. Perhaps in 2013. Definitely 2017. Probably in 2018-2019. And maybe even today.
Being wrong about Bitcoin is part of finally understanding it. It will test you, make you question everything, and in the words of BTC educator and privacy advocate Matt Odell, “Bitcoin will humble you”.
I’ve had my own stumbles on the way.
In a very public fashion in 2017, after years of using Bitcoin, trying to start a company with it, using it as my primary exchange vehicle between currencies, and generally being annoying about it at parties, I let out the bear.
In an article published in my own literary magazine Devolution Review in September 2017, I had a breaking point. The article was titled “Going Bearish on Bitcoin: Cryptocurrencies are the tulip mania of the 21st century”.
It was later republished in Huffington Post and across dozens of financial and crypto blogs at the time with another, more appropriate title: “Bitcoin Has Become About The Payday, Not Its Potential”.
As I laid out, my newfound bearishness had little to do with the technology itself or the promise of Bitcoin, and more to do with the cynical industry forming around it:
In the beginning, Bitcoin was something of a revolution to me. The digital currency represented everything from my rebellious youth.
It was a decentralized, denationalized, and digital currency operating outside the traditional banking and governmental system. It used tools of cryptography and connected buyers and sellers across national borders at minimal transaction costs.
…
The 21st-century version (of Tulip mania) has welcomed a plethora of slick consultants, hazy schemes dressed up as investor possibilities, and too much wishy-washy language for anything to really make sense to anyone who wants to use a digital currency to make purchases.
While I called out Bitcoin by name at the time, on reflection, I was really talking about the ICO craze, the wishy-washy consultants, and the altcoin ponzis.
What I was articulating — without knowing it — was the frame of NgU, or “numbers go up”. Rather than advocating for Bitcoin because of its uncensorability, proof-of-work, or immutability, the common mentality among newbies and the dollar-obsessed was that Bitcoin mattered because its price was a rocket ship.
And because Bitcoin was gaining in price, affinity tokens and projects that were imperfect forks of Bitcoin took off as well.
The price alone — rather than its qualities — were the reasons why you’d hear Uber drivers, finance bros, or your gym buddy mention Bitcoin. As someone who came to Bitcoin for philosophical reasons, that just sat wrong with me.
Maybe I had too many projects thrown in my face, or maybe I was too frustrated with the UX of Bitcoin apps and sites at the time. No matter what, I’ve since learned something.
I was at least somewhat wrong.
My own journey began in early 2011. One of my favorite radio programs, Free Talk Live, began interviewing guests and having discussions on the potential of Bitcoin. They tied it directly to a libertarian vision of the world: free markets, free people, and free banking. That was me, and I was in. Bitcoin was at about $5 back then (NgU).
I followed every article I could, talked about it with guests on my college radio show, and became a devoted redditor on r/Bitcoin. At that time, at least to my knowledge, there was no possible way to buy Bitcoin where I was living. Very weak.
I was probably wrong. And very wrong for not trying to acquire by mining or otherwise.
The next year, after moving to Florida, Bitcoin was a heavy topic with a friend of mine who shared the same vision (and still does, according to the Celsius bankruptcy documents). We talked about it with passionate leftists at Occupy Tampa in 2012, all the while trying to explain the ills of Keynesian central banking, and figuring out how to use Coinbase.
I began writing more about Bitcoin in 2013, writing a guide on “How to Avoid Bank Fees Using Bitcoin,” discussing its potential legalization in Germany, and interviewing Jeremy Hansen, one of the first political candidates in the U.S. to accept Bitcoin donations.
Even up until that point, I thought Bitcoin was an interesting protocol for sending and receiving money quickly, and converting it into fiat. The global connectedness of it, plus this cypherpunk mentality divorced from government control was both useful and attractive. I thought it was the perfect go-between.
But I was wrong.
When I gave my first public speech on Bitcoin in Vienna, Austria in December 2013, I had grown obsessed with Bitcoin’s adoption on dark net markets like Silk Road.
My theory, at the time, was the number and price were irrelevant. The tech was interesting, and a novel attempt. It was unlike anything before. But what was happening on the dark net markets, which I viewed as the true free market powered by Bitcoin, was even more interesting. I thought these markets would grow exponentially and anonymous commerce via BTC would become the norm.
While the price was irrelevant, it was all about buying and selling goods without permission or license.
Now I understand I was wrong.
Just because Bitcoin was this revolutionary technology that embraced pseudonymity did not mean that all commerce would decentralize as well. It did not mean that anonymous markets were intended to be the most powerful layer in the Bitcoin stack.
What I did not even anticipate is something articulated very well by noted Bitcoin OG Pierre Rochard: Bitcoin as a savings technology.
The ability to maintain long-term savings, practice self-discipline while stacking stats, and embrace a low-time preference was just not something on the mind of the Bitcoiners I knew at the time.
Perhaps I was reading into the hype while outwardly opposing it. Or perhaps I wasn’t humble enough to understand the true value proposition that many of us have learned years later.
In the years that followed, I bought and sold more times than I can count, and I did everything to integrate it into passion projects. I tried to set up a company using Bitcoin while at my university in Prague.
My business model depended on university students being technologically advanced enough to have a mobile wallet, own their keys, and be able to make transactions on a consistent basis. Even though I was surrounded by philosophically aligned people, those who would advance that to actually put Bitcoin into practice were sparse.
This is what led me to proclaim that “Technological Literacy is Doomed” in 2016.
And I was wrong again.
Indeed, since that time, the UX of Bitcoin-only applications, wallets, and supporting tech has vastly improved and onboarded millions more people than anyone thought possible. The entrepreneurship, coding excellence, and vision offered by Bitcoiners of all stripes have renewed a sense in me that this project is something built for us all — friends and enemies alike.
While many of us were likely distracted by flashy and pumpy altcoins over the years (me too, champs), most of us have returned to the Bitcoin stable.
Fast forward to today, there are entire ecosystems of creators, activists, and developers who are wholly reliant on the magic of Bitcoin’s protocol for their life and livelihood. The options are endless. The FUD is still present, but real proof of work stands powerfully against those forces.
In addition, there are now dozens of ways to use Bitcoin privately — still without custodians or intermediaries — that make it one of the most important assets for global humanity, especially in dictatorships.
This is all toward a positive arc of innovation, freedom, and pure independence. Did I see that coming? Absolutely not.
Of course, there are probably other shots you’ve missed on Bitcoin. Price predictions (ouch), the short-term inflation hedge, or the amount of institutional investment. While all of these may be erroneous predictions in the short term, we have to realize that Bitcoin is a long arc. It will outlive all of us on the planet, and it will continue in its present form for the next generation.
Being wrong about the evolution of Bitcoin is no fault, and is indeed part of the learning curve to finally understanding it all.
When your family or friends ask you about Bitcoin after your endless sessions explaining market dynamics, nodes, how mining works, and the genius of cryptographic signatures, try to accept that there is still so much we have to learn about this decentralized digital cash.
There are still some things you’ve gotten wrong about Bitcoin, and plenty more you’ll underestimate or get wrong in the future. That’s what makes it a beautiful journey. It’s a long road, but one that remains worth it.

2025-03-01 23:23:04What is HTML?
HTML (HyperText Markup Language) is the foundation of all webpages. Think of it as the framing of a house - it provides the basic structure that everything else builds upon.
Key Concepts
- HTML is a markup language, not a programming language
- It tells browsers how to structure web content
- Every HTML element is like a building block
- Browsers interpret HTML to display content
The Building Analogy
When building a webpage, think of it like constructing a house: - HTML: The framing and structure (walls, rooms, layout) - CSS: The design elements (paint, decorations, styling) - JavaScript: The functionality (plumbing, electrical, moving parts)
Basic HTML Structure
1. HTML Boilerplate
Every webpage starts with a basic template:
```html
Your Page Title ```
2. Understanding the Parts
<!DOCTYPE html>
: Tells browsers this is an HTML5 document<html>
: The root element of the page<head>
: Contains metadata about the document<body>
: Contains the visible content
Essential HTML Elements
1. Headings
HTML has six levels of headings: ```html
Main Title
Subtitle
Section Header
Smallest Heading
```
2. Paragraphs
```html
This is a paragraph of text. It can contain as much text as you need.
```
3. Images
html <img src="path-to-image.jpg" alt="Description of image" width="300">
4. Links
html <a href="https://example.com">Click here</a>
HTML Attributes
Attributes provide additional information or modify HTML elements:
html <tag attribute="value">Content</tag>
Common attributes: -
src
: Source path for images -href
: Destination for links -alt
: Alternative text for images -class
: CSS class names -id
: Unique identifier -style
: Inline CSS stylesSemantic HTML
What is Semantic HTML?
Semantic HTML uses meaningful tags that describe their content's purpose. This improves: - Accessibility - SEO (Search Engine Optimization) - Code readability - Maintainability
Common Semantic Elements
```html
```
Non-Semantic vs Semantic Example
Instead of: ```html
```
Use: ```html
```
Building Your First Webpage
1. Basic Structure
```html
My First Webpage Welcome to My First Webpage!
About Me
Hi, I'm learning web development with PlebDevs!
My Interests
I'm interested in Bitcoin, programming, and building cool stuff!
```
Best Practices
1. Structure
- Use proper indentation
- Keep code organized and readable
- Use semantic elements when possible
- Include all required elements (
DOCTYPE
,html
,head
,body
)
2. Content
- Use appropriate heading levels (start with
h1
) - Write descriptive
alt
text for images - Keep content meaningful and organized
- Use comments to explain complex sections
3. Accessibility
- Use semantic HTML elements
- Provide alternative text for images
- Maintain a logical heading structure
- Ensure content makes sense when read linearly
Common Issues and Solutions
Problem: Images Not Loading
```html
```
Problem: Links Not Working
```html
Click here ```
Next Steps
- Practice Building
- Create a personal webpage about yourself
- Include different types of content (text, images, links)
-
Use semantic HTML elements
-
Experiment with Structure
- Try different layouts
- Use various HTML elements
-
Pay attention to semantic meaning
-
Prepare for CSS
- Think about how you want your page to look
- Consider what styles you'll want to add
- Plan your layout structure
Exercise: Create Your Profile Page
Try creating a simple profile page using what you've learned:
- Use the HTML boilerplate
- Add a header with your name
- Include an "About Me" section
- Add a photo (if you want)
- List your interests or goals
- Add a footer with contact information
Remember to: - Use semantic HTML - Include appropriate headings - Add descriptive alt text for images - Keep your code clean and well-organized
Additional Resources
Remember: HTML is the foundation of web development. Take time to understand these basics well, as they'll serve as the building blocks for everything else you'll learn. Happy coding! 🚀

2025-01-01 17:39:51Heute möchte ich ein Gedicht mit euch teilen. Es handelt sich um eine Ballade des österreichischen Lyrikers Johann Gabriel Seidl aus dem 19. Jahrhundert. Mir sind diese Worte fest in Erinnerung, da meine Mutter sie perfekt rezitieren konnte, auch als die Kräfte schon langsam schwanden.
Dem originalen Titel «Die Uhr» habe ich für mich immer das Wort «innere» hinzugefügt. Denn der Zeitmesser – hier vermutliche eine Taschenuhr – symbolisiert zwar in dem Kontext das damalige Zeitempfinden und die Umbrüche durch die industrielle Revolution, sozusagen den Zeitgeist und das moderne Leben. Aber der Autor setzt sich philosophisch mit der Zeit auseinander und gibt seinem Werk auch eine klar spirituelle Dimension.
Das Ticken der Uhr und die Momente des Glücks und der Trauer stehen sinnbildlich für das unaufhaltsame Fortschreiten und die Vergänglichkeit des Lebens. Insofern könnte man bei der Uhr auch an eine Sonnenuhr denken. Der Rhythmus der Ereignisse passt uns vielleicht nicht immer in den Kram.
Was den Takt pocht, ist durchaus auch das Herz, unser «inneres Uhrwerk». Wenn dieses Meisterwerk einmal stillsteht, ist es unweigerlich um uns geschehen. Hoffentlich können wir dann dankbar sagen: «Ich habe mein Bestes gegeben.»
Ich trage, wo ich gehe, stets eine Uhr bei mir; \ Wieviel es geschlagen habe, genau seh ich an ihr. \ Es ist ein großer Meister, der künstlich ihr Werk gefügt, \ Wenngleich ihr Gang nicht immer dem törichten Wunsche genügt.
Ich wollte, sie wäre rascher gegangen an manchem Tag; \ Ich wollte, sie hätte manchmal verzögert den raschen Schlag. \ In meinen Leiden und Freuden, in Sturm und in der Ruh, \ Was immer geschah im Leben, sie pochte den Takt dazu.
Sie schlug am Sarge des Vaters, sie schlug an des Freundes Bahr, \ Sie schlug am Morgen der Liebe, sie schlug am Traualtar. \ Sie schlug an der Wiege des Kindes, sie schlägt, will's Gott, noch oft, \ Wenn bessere Tage kommen, wie meine Seele es hofft.
Und ward sie auch einmal träger, und drohte zu stocken ihr Lauf, \ So zog der Meister immer großmütig sie wieder auf. \ Doch stände sie einmal stille, dann wär's um sie geschehn, \ Kein andrer, als der sie fügte, bringt die Zerstörte zum Gehn.
Dann müßt ich zum Meister wandern, der wohnt am Ende wohl weit, \ Wohl draußen, jenseits der Erde, wohl dort in der Ewigkeit! \ Dann gäb ich sie ihm zurücke mit dankbar kindlichem Flehn: \ Sieh, Herr, ich hab nichts verdorben, sie blieb von selber stehn.
Johann Gabriel Seidl (1804-1875)

2024-12-31 20:18:59Scuttlebutt foi iniciado em maio de 2014 por Dominic Tarr ( dominictarr ) como uma rede social alternativa off-line, primeiro para convidados, que permite aos usuários obter controle total de seus dados e privacidade. Secure Scuttlebutt (ssb) foi lançado pouco depois, o que coloca a privacidade em primeiro plano com mais recursos de criptografia.
Se você está se perguntando de onde diabos veio o nome Scuttlebutt:
Este termo do século 19 para uma fofoca vem do Scuttlebutt náutico: “um barril de água mantido no convés, com um buraco para uma xícara”. A gíria náutica vai desde o hábito dos marinheiros de se reunir pelo boato até a fofoca, semelhante à fofoca do bebedouro.
Marinheiros se reunindo em torno da rixa. ( fonte )
Dominic descobriu o termo boato em um artigo de pesquisa que leu.
Em sistemas distribuídos, fofocar é um processo de retransmissão de mensagens ponto a ponto; as mensagens são disseminadas de forma análoga ao “boca a boca”.
Secure Scuttlebutt é um banco de dados de feeds imutáveis apenas para acréscimos, otimizado para replicação eficiente para protocolos ponto a ponto. Cada usuário tem um log imutável somente para acréscimos no qual eles podem gravar. Eles gravam no log assinando mensagens com sua chave privada. Pense em um feed de usuário como seu próprio diário de bordo, como um diário de bordo (ou diário do capitão para os fãs de Star Trek), onde eles são os únicos autorizados a escrever nele, mas têm a capacidade de permitir que outros amigos ou colegas leiam ao seu diário de bordo, se assim o desejarem.
Cada mensagem possui um número de sequência e a mensagem também deve fazer referência à mensagem anterior por seu ID. O ID é um hash da mensagem e da assinatura. A estrutura de dados é semelhante à de uma lista vinculada. É essencialmente um log somente de acréscimo de JSON assinado. Cada item adicionado a um log do usuário é chamado de mensagem.
Os logs do usuário são conhecidos como feed e um usuário pode seguir os feeds de outros usuários para receber suas atualizações. Cada usuário é responsável por armazenar seu próprio feed. Quando Alice assina o feed de Bob, Bob baixa o log de feed de Alice. Bob pode verificar se o registro do feed realmente pertence a Alice verificando as assinaturas. Bob pode verificar as assinaturas usando a chave pública de Alice.
Estrutura de alto nível de um feed
Pubs são servidores de retransmissão conhecidos como “super peers”. Pubs conectam usuários usuários e atualizações de fofocas a outros usuários conectados ao Pub. Um Pub é análogo a um pub da vida real, onde as pessoas vão para se encontrar e se socializar. Para ingressar em um Pub, o usuário deve ser convidado primeiro. Um usuário pode solicitar um código de convite de um Pub; o Pub simplesmente gerará um novo código de convite, mas alguns Pubs podem exigir verificação adicional na forma de verificação de e-mail ou, com alguns Pubs, você deve pedir um código em um fórum público ou chat. Pubs também podem mapear aliases de usuário, como e-mails ou nome de usuário, para IDs de chave pública para facilitar os pares de referência.
Depois que o Pub enviar o código de convite ao usuário, o usuário resgatará o código, o que significa que o Pub seguirá o usuário, o que permite que o usuário veja as mensagens postadas por outros membros do Pub, bem como as mensagens de retransmissão do Pub pelo usuário a outros membros do Pub.
Além de retransmitir mensagens entre pares, os Pubs também podem armazenar as mensagens. Se Alice estiver offline e Bob transmitir atualizações de feed, Alice perderá a atualização. Se Alice ficar online, mas Bob estiver offline, não haverá como ela buscar o feed de Bob. Mas com um Pub, Alice pode buscar o feed no Pub mesmo se Bob estiver off-line porque o Pub está armazenando as mensagens. Pubs são úteis porque assim que um colega fica online, ele pode sincronizar com o Pub para receber os feeds de seus amigos potencialmente offline.
Um usuário pode, opcionalmente, executar seu próprio servidor Pub e abri-lo ao público ou permitir que apenas seus amigos participem, se assim o desejarem. Eles também podem ingressar em um Pub público. Aqui está uma lista de Pubs públicos em que todos podem participar . Explicaremos como ingressar em um posteriormente neste guia. Uma coisa importante a observar é que o Secure Scuttlebutt em uma rede social somente para convidados significa que você deve ser “puxado” para entrar nos círculos sociais. Se você responder às mensagens, os destinatários não serão notificados, a menos que estejam seguindo você de volta. O objetivo do SSB é criar “ilhas” isoladas de redes pares, ao contrário de uma rede pública onde qualquer pessoa pode enviar mensagens a qualquer pessoa.

Patchwork - Uma GUI SSB (Descontinuado)
Patchwork é o aplicativo de mensagens e compartilhamento descentralizado construído em cima do SSB . O protocolo scuttlebutt em si não mantém um conjunto de feeds nos quais um usuário está interessado, então um cliente é necessário para manter uma lista de feeds de pares em que seu respectivo usuário está interessado e seguindo.
Fonte: scuttlebutt.nz
Quando você instala e executa o Patchwork, você só pode ver e se comunicar com seus pares em sua rede local. Para acessar fora de sua LAN, você precisa se conectar a um Pub. Um pub é apenas para convidados e eles retransmitem mensagens entre você e seus pares fora de sua LAN e entre outros Pubs.
Lembre-se de que você precisa seguir alguém para receber mensagens dessa pessoa. Isso reduz o envio de mensagens de spam para os usuários. Os usuários só veem as respostas das pessoas que seguem. Os dados são sincronizados no disco para funcionar offline, mas podem ser sincronizados diretamente com os pares na sua LAN por wi-fi ou bluetooth.
Patchbay - Uma GUI Alternativa
Patchbay é um cliente de fofoca projetado para ser fácil de modificar e estender. Ele usa o mesmo banco de dados que Patchwork e Patchfoo , então você pode facilmente dar uma volta com sua identidade existente.
Planetary - GUI para IOS
Planetary é um app com pubs pré-carregados para facilitar integração.
Manyverse - GUI para Android
Manyverse é um aplicativo de rede social com recursos que você esperaria: posts, curtidas, perfis, mensagens privadas, etc. Mas não está sendo executado na nuvem de propriedade de uma empresa, em vez disso, as postagens de seus amigos e todos os seus dados sociais vivem inteiramente em seu telefone .

2025-03-06 15:32:33Ascolta bene!
Absorb from suffering the lessons that joy would never dare to offer you.
Davvero, all strong men are truly tested only when everything falls apart. It is easy to feel good and motivated on happy days. But in life's great adversities, we discover whether we can truly withstand what our optimism conveniently sweeps under the rug.
When you are dragged by powerful currents, regretting diving into deep waters is useless. The only path is to fight with strong strokes to avoid drowning and cling to the first rock or log that appears on the riverbank to survive. Likewise, my friend, your regrets and remorse are like concrete weights tied to your feet, dragging you deeper into despair.
Which man has never tormented himself thinking, "What if I had done things differently?" The failure of your decisions must be confronted with all your strength. Do not lament what you could have done or failed to do—focus your mind on fixing what is still within your control. This is not about motivation; it is about survival. A wound, once healed, becomes a scar. A mistake, once learned from, becomes a valuable lesson.
Anguish, sadness, and frustration are anchors that paralyze and offer no benefit. You must not stop your journey just because your shoes have worn out. You cannot bury your will to win simply because of the defeats along the way. Nothing will ever be easy—it never was. Anyone who says otherwise is a cunning liar!
Infatti, if there is one piece of advice I can give to each of you, it is this: never allow yourself to succumb when everything collapses, and your plans slip through your fingers.
Thank you for reading, my friend!
If this message resonated with you, consider leaving your "🥃" as a token of appreciation.
A toast to our family!

2025-03-06 14:49:57Good morning, readers!
In Nicaragua, the regime is increasingly cracking down on civil society, imposing new financial regulations on non-governmental organizations (NGOs) that require them to disclose donors and report all financial transactions — further restricting their ability to operate independently. Meanwhile, in Iraq, the central bank governor announced plans to introduce a central bank digital currency (CBDC) to replace cash in circulation. CBDCs are a mechanism for using digital currencies to centralize financial control.
In freedom tech news, Alby Go, a mobile Bitcoin Lightning wallet, added support for Pick n Pay QR codes, making it easier for South Africans to pay with Bitcoin at one of the country’s largest retailers. Additionally, Bitcoin Safe, an open-source Bitcoin wallet designed to simplify self-custody, introduced support for Burmese and Korean Languages, making the wallet more accessible to activists, dissidents, and individuals in these regions.
We end with a new discussion from 21st Capital, where Alex Gladstein, Chief Strategy Officer at HRF, joins Ziya Sadr, an Iranian activist and Bitcoin educator, to explore Bitcoin’s role in fighting financial repression and advancing global freedom. Sadr, who was detained by the Iranian regime during the Mahsa Amini protests, shares a sobering account of authoritarian control and the ways Bitcoin can help alleviate these struggles.
Now, let’s get right to it!

GLOBAL NEWS
Nicaragua | Increases Financial Surveillance of NGOs
Nicaragua’s dictator, Daniel Ortega, intensified his crackdown on civil society with two new regulations that significantly increase the Ministry of the Interior’s (MINT) authority over national and foreign NGOs. The new regulations require NGOs to submit financial documentation, disclose their donors, and report all financial transactions. Using this information, authorities can now classify organizations as “threats,” conduct surprise inspections, impose sanctions, seize assets, and force closure. These regulations, framed as efforts to combat “digital terrorism,” intensify state surveillance and control and are a continuation of the regime’s systematic use of financial repression to silence dissent. This year alone, Ortega shut down 15 NGOs, and since 2021, he has closed over 5,600.
El Salvador | IMF Approves 1.4 Billion Loan With Further Restrictions
The International Monetary Fund (IMF) has officially approved its $1.4 billion loan to El Salvador while reinforcing even stricter limits on Bitcoin. This comes after last month’s legal reforms that made Bitcoin acceptance voluntary and prohibited its use for tax payments. The finalized deal, which grants an immediate $113 million disbursement, confines “government engagement in Bitcoin-related economic activities, as well as government transactions in and purchases of Bitcoin.” Despite these constraints, President Bukele has continued to flaunt Bitcoin purchases on social media, leaving many questions unanswered. Where does this bitcoin come from? Who controls the wallets? The lack of transparency remains.
Iraq | Issuing CBDC to Replace Cash
Iraq’s central bank governor, Ali Al-Allaq, announced that “the Iraqi central bank is now moving to create its own digital currency which will gradually replace paper notes.” Al-Allaq highlighted that this move aligns with broader “radical” changes in the global financial system. This news comes after Iraq banned all digital assets in 2017, citing concerns over financial crime and terrorism. Yet, its embrace of a CBDC over decentralized currencies like Bitcoin highlights a familiar pattern. China, Nigeria, and Russia have also pushed for CBDCs while restricting Bitcoin. Evidently, authoritarian regimes prefer financial control to remain in their own hands rather than risk empowering the public.
Nigeria | Frees Tigran Gambaryan in Exchange for Greater Financial Surveillance
In October 2024, Nigeria released Tigran Gambaryan, a former Binance executive accused of money laundering and contributing to the naira’s devaluation — though, in reality, he was a scapegoat for the regime’s economic mismanagement. According to The Rage, his release was secured through a deal with the US to help Nigeria prosecute “cryptocurrency and financial crimes.” Soon after, the two countries announced the creation of a “Bilateral Liaison Group on Illicit Finance and Cryptocurrencies” to expand Nigeria’s surveillance capabilities and “pursue cybercrime investigations and prosecutions.” Gambaryan, who described his prison conditions as “torture,” now faces an unsettling reality: his freedom may have come at the cost of strengthening an authoritarian regime notorious for its financial repression.
Turkey | X Blocks Accounts of Three Journalists at Regimes Request
X recently blocked the accounts of three Kurdish journalists in Turkey — Abdurrahman Gök, Oktay Candemir, and Ruşen Takva — following a Turkish government request citing concerns over “national security.” The journalists, known for exposing government corruption and reporting on Kurdish issues, now join a growing list of silenced Turkish reporters. This comes as Turkey intensifies its crackdown on independent media through arrests, legal pressure, and censorship. With 95% of media outlets in Turkey complying with the regime, social platforms remain one of the last places for free expression. Yet, as X and other platforms increasingly comply with authoritarian demands, access to independent information shrinks. This escalating repression underscores the need for censorship-resistant alternatives like nostr, where government pressure or corporate compliance cannot easily suppress speech.

BITCOIN AND FREEDOM TECH NEWS
Nostr Wallet Connect | Introduces Pull Request for On-Chain Send and Receive
Nostr Wallet Connect (NWC), a protocol that connects Bitcoin Lightning wallets and applications, is developing a potential upgrade: support for on-chain Bitcoin transactions. Currently, NWC is designed for Lightning transactions. This new update would allow users to also send and receive on-chain Bitcoin transactions, which are slower and less private, but more secure with higher send and receive limits. This means users and apps can more easily move funds between Lightning and regular Bitcoin wallets, making NWC more practical and flexible. This upgrade enhances financial resilience for dissidents and activists by providing a more secure and flexible way to store and move Bitcoin.
Bitcoin Safe | Adds Support for Burmese and Korean Languages
Bitcoin Safe, an open-source Bitcoin wallet designed to make self-custody simple — even for non-technical users — introduced support for Burmese and Korean Languages. This support makes the wallet more accessible to activists, dissidents, and individuals in these regions, empowering them with uncensorable and unseizable money. Bitcoin Safe guides users through the entire setup process, offering step-by-step instructions for single-signature wallets (where one private key controls your Bitcoin) and multisignature wallets (which require multiple private keys for added security). By breaking down barriers to Bitcoin self-custody, Bitcoin Safe is making financial freedom accessible to those who need it most.
Frostr | Turn Your Nostr Private Key into a Rotatable Multisig
Frostr is an experimental new tool that adds a layer of security to a user’s nostr private key by splitting it into multiple parts. Instead of using a single key, Frostr divides the key into shares, requiring a subset of these shares to sign messages on nostr. This offers two key benefits. First, greater security; even if one share is lost or stolen, a user’s full key remains secret and in their control. Second, flexible key rotation; users can replace or update shares of the key without changing their digital identity. This is an important advancement for activists, journalists, and human rights defenders. Many authoritarian regimes track, censor, and punish those who speak freely. If an activist’s private key is compromised, their digital identity and safety could be at risk. Frostr removes this single point of failure and empowers users to communicate freely, securely, and flexibly, even in hostile environments.
Alby Go | Integrates Pick n Pay QRs for Bitcoin Payments in South Africa
Alby Go, a mobile Bitcoin Lightning wallet, added support for Pick n Pay QR codes, making it easier for South Africans to pay with Bitcoin at one of the country’s largest retailers. The update also integrates BTC map, offering users a detailed directory of merchants that accept Bitcoin. These changes make everyday Bitcoin payments more practical, expand access to businesses that accept Bitcoin, and give South Africans an alternative to the country’s unstable financial system and currency.
bitcoin++ | Announces Freedom and Privacy Edition
bitcoin++, a bitcoin-only developer conference series, is set to return on August 7-8, 2025, with a dedicated focus on freedom and privacy. Taking place in Riga, Latvia the event will bring together privacy advocates, developers, and freedom tech enthusiasts to explore the latest developments in privacy tech, censorship resistance, and open-source development on Bitcoin.

Welcome to the PlebDevs starter course! I'm Austin, the founder of PlebDevs, and I'll be walking you through this short intro starter course that will get you up and running and interacting with the rest of the content on the platform. If you're here, I'm assuming you're new to coding or just starting out. If you already have experience and have your bearings down, there's lots more intermediate and advanced content on the platform. This course is designed for absolute beginners.
Course Goals
Overall PlebDevs Goals
- Learn how to code
- Build Bitcoin/Lightning/Nostr apps
- Become a developer
This is a big journey with a lot of pieces and things to learn. The starter course is going to get you on that path as quickly as possible and make it a smooth journey.
Starter Course Objectives
- Give you an easy, high-level overview of the dev journey
- Get you set up and comfortable in a development environment where you'll write and ship code
- Give you basic experience in the languages covered in our courses and workshops
There's lots of material out there that will just tell you exactly what to do and not explain why but I want you to actually understand for yourself. I want you to have a good mental model of what this journey is going to be like, what it's going to be like actually writing and pushing code. And then we're going to start getting our hands dirty and gain real experience.

2024-12-21 09:54:49Falls du beim Lesen des Titels dieses Newsletters unwillkürlich an positive Neuigkeiten aus dem globalen polit-medialen Irrenhaus oder gar aus dem wirtschaftlichen Umfeld gedacht hast, darf ich dich beglückwünschen. Diese Assoziation ist sehr löblich, denn sie weist dich als unverbesserlichen Optimisten aus. Leider muss ich dich diesbezüglich aber enttäuschen. Es geht hier um ein anderes Thema, allerdings sehr wohl ein positives, wie ich finde.
Heute ist ein ganz besonderer Tag: die Wintersonnenwende. Genau gesagt hat heute morgen um 10:20 Uhr Mitteleuropäischer Zeit (MEZ) auf der Nordhalbkugel unseres Planeten der astronomische Winter begonnen. Was daran so außergewöhnlich ist? Der kürzeste Tag des Jahres war gestern, seit heute werden die Tage bereits wieder länger! Wir werden also jetzt jeden Tag ein wenig mehr Licht haben.
Für mich ist dieses Ereignis immer wieder etwas kurios: Es beginnt der Winter, aber die Tage werden länger. Das erscheint mir zunächst wie ein Widerspruch, denn meine spontanen Assoziationen zum Winter sind doch eher Kälte und Dunkelheit, relativ zumindest. Umso erfreulicher ist der emotionale Effekt, wenn dann langsam die Erkenntnis durchsickert: Ab jetzt wird es schon wieder heller!
Natürlich ist es kalt im Winter, mancherorts mehr als anderswo. Vielleicht jedoch nicht mehr lange, wenn man den Klimahysterikern glauben wollte. Mindestens letztes Jahr hat Väterchen Frost allerdings gleich zu Beginn seiner Saison – und passenderweise während des globalen Überhitzungsgipfels in Dubai – nochmal richtig mit der Faust auf den Tisch gehauen. Schnee- und Eischaos sind ja eigentlich in der Agenda bereits nicht mehr vorgesehen. Deswegen war man in Deutschland vermutlich in vorauseilendem Gehorsam schon nicht mehr darauf vorbereitet und wurde glatt lahmgelegt.
Aber ich schweife ab. Die Aussicht auf nach und nach mehr Licht und damit auch Wärme stimmt mich froh. Den Zusammenhang zwischen beidem merkt man in Andalusien sehr deutlich. Hier, wo die Häuser im Winter arg auskühlen, geht man zum Aufwärmen raus auf die Straße oder auf den Balkon. Die Sonne hat auch im Winter eine erfreuliche Kraft. Und da ist jede Minute Gold wert.
Außerdem ist mir vor Jahren so richtig klar geworden, warum mir das südliche Klima so sehr gefällt. Das liegt nämlich nicht nur an der Sonne als solcher, oder der Wärme – das liegt vor allem am Licht. Ohne Licht keine Farben, das ist der ebenso simple wie gewaltige Unterschied zwischen einem deprimierenden matschgraubraunen Winter und einem fröhlichen bunten. Ein großes Stück Lebensqualität.
Mir gefällt aber auch die Symbolik dieses Tages: Licht aus der Dunkelheit, ein Wendepunkt, ein Neuanfang, neue Möglichkeiten, Übergang zu neuer Aktivität. In der winterlichen Stille keimt bereits neue Lebendigkeit. Und zwar in einem Zyklus, das wird immer wieder so geschehen. Ich nehme das gern als ein Stück Motivation, es macht mir Hoffnung und gibt mir Energie.
Übrigens ist parallel am heutigen Tag auf der südlichen Halbkugel Sommeranfang. Genau im entgegengesetzten Rhythmus, sich ergänzend, wie Yin und Yang. Das alles liegt an der Schrägstellung der Erdachse, die ist nämlich um 23,4º zur Umlaufbahn um die Sonne geneigt. Wir erinnern uns, gell?
Insofern bleibt eindeutig festzuhalten, dass “schräg sein” ein willkommener, wichtiger und positiver Wert ist. Mit anderen Worten: auch ungewöhnlich, eigenartig, untypisch, wunderlich, kauzig, … ja sogar irre, spinnert oder gar “quer” ist in Ordnung. Das schließt das Denken mit ein.
In diesem Sinne wünsche ich euch allen urige Weihnachtstage!
Dieser Beitrag ist letztes Jahr in meiner Denkbar erschienen.

Fiduciary duty is the obligation to act in the client’s best interests at all times, prioritizing their needs above the advisor’s own, ensuring honesty, transparency, and avoiding conflicts of interest in all recommendations and actions.
This is something all advisors in the BFAN take very seriously; after all, we are legally required to do so. For the average advisor this is a fairly easy box to check. All you essentially have to do is have someone take a 5-minute risk assessment, fill out an investment policy statement, and then throw them in the proverbial 60/40 portfolio. You have thousands of investment options to choose from and you can reasonably explain how your client is theoretically insulated from any move in the \~markets\~. From the traditional financial advisor perspective, you could justify nearly anything by putting a client into this type of portfolio. All your bases were pretty much covered from return profile, regulatory, compliance, investment options, etc. It was just too easy. It became the household standard and now a meme.
As almost every real bitcoiner knows, the 60/40 portfolio is moving into psyop territory, and many financial advisors get clowned on for defending this relic on bitcoin twitter. I’m going to specifically poke fun at the ‘40’ part of this portfolio.
The ‘40’ represents fixed income, defined as…
An investment type that provides regular, set interest payments, such as bonds or treasury securities, and returns the principal at maturity. It’s generally considered a lower-risk asset class, used to generate stable income and preserve capital.
Historically, this part of the portfolio was meant to weather the volatility in the equity markets and represent the “safe” investments. Typically, some sort of bond.
First and foremost, the fixed income section is most commonly constructed with U.S. Debt. There are a couple main reasons for this. Most financial professionals believe the same fairy tale that U.S. Debt is “risk free” (lol). U.S. debt is also one of the largest and most liquid assets in the market which comes with a lot of benefits.
There are many brilliant bitcoiners in finance and economics that have sounded the alarm on the U.S. debt ticking time bomb. I highly recommend readers explore the work of Greg Foss, Lawrence Lepard, Lyn Alden, and Saifedean Ammous. My very high-level recap of their analysis:
-
A bond is a contract in which Party A (the borrower) agrees to repay Party B (the lender) their principal plus interest over time.
-
The U.S. government issues bonds (Treasury securities) to finance its operations after tax revenues have been exhausted.
-
These are traditionally viewed as “risk-free” due to the government’s historical reliability in repaying its debts and the strength of the U.S. economy
-
U.S. bonds are seen as safe because the government has control over the dollar (world reserve asset) and, until recently (20 some odd years), enjoyed broad confidence that it would always honor its debts.
-
This perception has contributed to high global demand for U.S. debt but, that is quickly deteriorating.
-
The current debt situation raises concerns about sustainability.
-
The U.S. has substantial obligations, and without sufficient productivity growth, increasing debt may lead to a cycle where borrowing to cover interest leads to more debt.
-
This could result in more reliance on money creation (printing), which can drive inflation and further debt burdens.
In the words of Lyn Alden “Nothing stops this train”
Those obligations are what makes up the 40% of most the fixed income in your portfolio. So essentially you are giving money to one of the worst capital allocators in the world (U.S. Gov’t) and getting paid back with printed money.
As someone who takes their fiduciary responsibility seriously and understands the debt situation we just reviewed, I think it’s borderline negligent to put someone into a classic 60% (equities) / 40% (fixed income) portfolio without serious scrutiny of the client’s financial situation and options available to them. I certainly have my qualms with equities at times, but overall, they are more palatable than the fixed income portion of the portfolio. I don’t like it either, but the money is broken and the unit of account for nearly every equity or fixed income instrument (USD) is fraudulent. It’s a paper mache fade that is quite literally propped up by the money printer.
To briefly be as most charitable as I can – It wasn’t always this way. The U.S. Dollar used to be sound money, we used to have government surplus instead of mathematically certain deficits, The U.S. Federal Government didn’t used to have a money printing addiction, and pre-bitcoin the 60/40 portfolio used to be a quality portfolio management strategy. Those times are gone.
Now the fun part. How does bitcoin fix this?
Bitcoin fixes this indirectly. Understanding investment criteria changes via risk tolerance, age, goals, etc. A client may still have a need for “fixed income” in the most literal definition – Low risk yield. Now you may be thinking that yield is a bad word in bitcoin land, you’re not wrong, so stay with me. Perpetual motion machine crypto yield is fake and largely where many crypto scams originate. However, that doesn’t mean yield in the classic finance sense does not exist in bitcoin, it very literally does. Fortunately for us bitcoiners there are many other smart, driven, and enterprising bitcoiners that understand this problem and are doing something to address it. These individuals are pioneering new possibilities in bitcoin and finance, specifically when it comes to fixed income.
Here are some new developments –
Private Credit Funds – The Build Asset Management Secured Income Fund I is a private credit fund created by Build Asset Management. This fund primarily invests in bitcoin-backed, collateralized business loans originated by Unchained, with a secured structure involving a multi-signature, over-collateralized setup for risk management. Unchained originates loans and sells them to Build, which pools them into the fund, enabling investors to share in the interest income.
Dynamics
- Loan Terms: Unchained issues loans at interest rates around 14%, secured with a 2/3 multi-signature vault backed by a 40% loan-to-value (LTV) ratio.
- Fund Mechanics: Build buys these loans from Unchained, thus providing liquidity to Unchained for further loan originations, while Build manages interest payments to investors in the fund.
Pros
- The fund offers a unique way to earn income via bitcoin-collateralized debt, with protection against rehypothecation and strong security measures, making it attractive for investors seeking exposure to fixed income with bitcoin.
Cons
- The fund is only available to accredited investors, which is a regulatory standard for private credit funds like this.
Corporate Bonds – MicroStrategy Inc. (MSTR), a business intelligence company, has leveraged its corporate structure to issue bonds specifically to acquire bitcoin as a reserve asset. This approach allows investors to indirectly gain exposure to bitcoin’s potential upside while receiving interest payments on their bond investments. Some other publicly traded companies have also adopted this strategy, but for the sake of this article we will focus on MSTR as they are the biggest and most vocal issuer.
Dynamics
-
Issuance: MicroStrategy has issued senior secured notes in multiple offerings, with terms allowing the company to use the proceeds to purchase bitcoin.
-
Interest Rates: The bonds typically carry high-yield interest rates, averaging around 6-8% APR, depending on the specific issuance and market conditions at the time of issuance.
-
Maturity: The bonds have varying maturities, with most structured for multi-year terms, offering investors medium-term exposure to bitcoin’s value trajectory through MicroStrategy’s holdings.
Pros
-
Indirect Bitcoin exposure with income provides a unique opportunity for investors seeking income from bitcoin-backed debt.
-
Bonds issued by MicroStrategy offer relatively high interest rates, appealing for fixed-income investors attracted to the higher risk/reward scenarios.
Cons
-
There are credit risks tied to MicroStrategy’s financial health and bitcoin’s performance. A significant drop in bitcoin prices could strain the company’s ability to service debt, increasing credit risk.
-
Availability: These bonds are primarily accessible to institutional investors and accredited investors, limiting availability for retail investors.
Interest Payable in Bitcoin – River has introduced an innovative product, bitcoin Interest on Cash, allowing clients to earn interest on their U.S. dollar deposits, with the interest paid in bitcoin.
Dynamics
-
Interest Payment: Clients earn an annual interest rate of 3.8% on their cash deposits. The accrued interest is converted to Bitcoin daily and paid out monthly, enabling clients to accumulate Bitcoin over time.
-
Security and Accessibility: Cash deposits are insured up to $250,000 through River’s banking partner, Lead Bank, a member of the FDIC. All Bitcoin holdings are maintained in full reserve custody, ensuring that client assets are not lent or leveraged.
Pros
-
There are no hidden fees or minimum balance requirements, and clients can withdraw their cash at any time.
-
The 3.8% interest rate provides a predictable income stream, akin to traditional fixed-income investments.
Cons
-
While the interest rate is fixed, the value of the Bitcoin received as interest can fluctuate, introducing potential variability in the investment’s overall return.
-
Interest rate payments are on the lower side
Admittedly, this is a very small list, however, these types of investments are growing more numerous and meaningful. The reality is the existing options aren’t numerous enough to service every client that has a need for fixed income exposure. I challenge advisors to explore innovative options for fixed income exposure outside of sovereign debt, as that is most certainly a road to nowhere. It is my wholehearted belief and call to action that we need more options to help clients across the risk and capital allocation spectrum access a sound money standard.
Additional Resources
-
River: The future of saving is here: Earn 3.8% on cash. Paid in Bitcoin.

2024-12-13 19:30:32Das Betriebsklima ist das einzige Klima, \ das du selbst bestimmen kannst. \ Anonym
Eine Strategie zur Anpassung an den Klimawandel hat das deutsche Bundeskabinett diese Woche beschlossen. Da «Wetterextreme wie die immer häufiger auftretenden Hitzewellen und Starkregenereignisse» oft desaströse Auswirkungen auf Mensch und Umwelt hätten, werde eine Anpassung an die Folgen des Klimawandels immer wichtiger. «Klimaanpassungsstrategie» nennt die Regierung das.
Für die «Vorsorge vor Klimafolgen» habe man nun erstmals klare Ziele und messbare Kennzahlen festgelegt. So sei der Erfolg überprüfbar, und das solle zu einer schnelleren Bewältigung der Folgen führen. Dass sich hinter dem Begriff Klimafolgen nicht Folgen des Klimas, sondern wohl «Folgen der globalen Erwärmung» verbergen, erklärt den Interessierten die Wikipedia. Dabei ist das mit der Erwärmung ja bekanntermaßen so eine Sache.
Die Zunahme schwerer Unwetterereignisse habe gezeigt, so das Ministerium, wie wichtig eine frühzeitige und effektive Warnung der Bevölkerung sei. Daher solle es eine deutliche Anhebung der Nutzerzahlen der sogenannten Nina-Warn-App geben.
Die ARD spurt wie gewohnt und setzt die Botschaft zielsicher um. Der Artikel beginnt folgendermaßen:
«Die Flut im Ahrtal war ein Schock für das ganze Land. Um künftig besser gegen Extremwetter gewappnet zu sein, hat die Bundesregierung eine neue Strategie zur Klimaanpassung beschlossen. Die Warn-App Nina spielt eine zentrale Rolle. Der Bund will die Menschen in Deutschland besser vor Extremwetter-Ereignissen warnen und dafür die Reichweite der Warn-App Nina deutlich erhöhen.»
Die Kommunen würden bei ihren «Klimaanpassungsmaßnahmen» vom Zentrum KlimaAnpassung unterstützt, schreibt das Umweltministerium. Mit dessen Aufbau wurden das Deutsche Institut für Urbanistik gGmbH, welches sich stark für Smart City-Projekte engagiert, und die Adelphi Consult GmbH beauftragt.
Adelphi beschreibt sich selbst als «Europas führender Think-and-Do-Tank und eine unabhängige Beratung für Klima, Umwelt und Entwicklung». Sie seien «global vernetzte Strateg*innen und weltverbessernde Berater*innen» und als «Vorreiter der sozial-ökologischen Transformation» sei man mit dem Deutschen Nachhaltigkeitspreis ausgezeichnet worden, welcher sich an den Zielen der Agenda 2030 orientiere.
Über die Warn-App mit dem niedlichen Namen Nina, die möglichst jeder auf seinem Smartphone installieren soll, informiert das Bundesamt für Bevölkerungsschutz und Katastrophenhilfe (BBK). Gewarnt wird nicht nur vor Extrem-Wetterereignissen, sondern zum Beispiel auch vor Waffengewalt und Angriffen, Strom- und anderen Versorgungsausfällen oder Krankheitserregern. Wenn man die Kategorie Gefahreninformation wählt, erhält man eine Dosis von ungefähr zwei Benachrichtigungen pro Woche.
Beim BBK erfahren wir auch einiges über die empfohlenen Systemeinstellungen für Nina. Der Benutzer möge zum Beispiel den Zugriff auf die Standortdaten «immer zulassen», und zwar mit aktivierter Funktion «genauen Standort verwenden». Die Datennutzung solle unbeschränkt sein, auch im Hintergrund. Außerdem sei die uneingeschränkte Akkunutzung zu aktivieren, der Energiesparmodus auszuschalten und das Stoppen der App-Aktivität bei Nichtnutzung zu unterbinden.
Dass man so dramatische Ereignisse wie damals im Ahrtal auch anders bewerten kann als Regierungen und Systemmedien, hat meine Kollegin Wiltrud Schwetje anhand der Tragödie im spanischen Valencia gezeigt. Das Stichwort «Agenda 2030» taucht dabei in einem Kontext auf, der wenig mit Nachhaltigkeitspreisen zu tun hat.

Ah, February! The month of love! Well, it is if Valentine's Day and a few slices of bread have anything to say about it! All of this month's Sunday Singles all revolved around this theme. How can we portray to folks our love for, well, Love! We even changed our logo on Valentine's Day this year and released the art for it as a note using the NOSTR protocol.
The adventure known as Questline released two more pages of its story ending the month with readers wondering how will the gang deal with their first adversary.
As usual a piece of Concept Art and Bitcoin Art were released. However, some will notice that the art work was released with a new framing standard which we plan to continue.
Last of all, we started releasing merchandise with an exclusive bundle inspired by this month's Toast's Comic Collection. You'll see more information about this near the end of this issue of The Whole Grain.

2024-12-06 18:21:15Die Ungerechtigkeit ist uns nur in dem Falle angenehm,\ dass wir Vorteile aus ihr ziehen;\ in jedem andern hegt man den Wunsch,\ dass der Unschuldige in Schutz genommen werde.\ Jean-Jacques Rousseau
Politiker beteuern jederzeit, nur das Beste für die Bevölkerung zu wollen – nicht von ihr. Auch die zahlreichen unsäglichen «Corona-Maßnahmen» waren angeblich zu unserem Schutz notwendig, vor allem wegen der «besonders vulnerablen Personen». Daher mussten alle möglichen Restriktionen zwangsweise und unter Umgehung der Parlamente verordnet werden.
Inzwischen hat sich immer deutlicher herausgestellt, dass viele jener «Schutzmaßnahmen» den gegenteiligen Effekt hatten, sie haben den Menschen und den Gesellschaften enorm geschadet. Nicht nur haben die experimentellen Geninjektionen – wie erwartet – massive Nebenwirkungen, sondern Maskentragen schadet der Psyche und der Entwicklung (nicht nur unserer Kinder) und «Lockdowns und Zensur haben Menschen getötet».
Eine der wichtigsten Waffen unserer «Beschützer» ist die Spaltung der Gesellschaft. Die tiefen Gräben, die Politiker, Lobbyisten und Leitmedien praktisch weltweit ausgehoben haben, funktionieren leider nahezu in Perfektion. Von ihren persönlichen Erfahrungen als Kritikerin der Maßnahmen berichtete kürzlich eine Schweizerin im Interview mit Transition News. Sie sei schwer enttäuscht und verspüre bis heute eine Hemmschwelle und ein seltsames Unwohlsein im Umgang mit «Geimpften».
Menschen, die aufrichtig andere schützen wollten, werden von einer eindeutig politischen Justiz verfolgt, verhaftet und angeklagt. Dazu zählen viele Ärzte, darunter Heinrich Habig, Bianca Witzschel und Walter Weber. Über den aktuell laufenden Prozess gegen Dr. Weber hat Transition News mehrfach berichtet (z.B. hier und hier). Auch der Selbstschutz durch Verweigerung der Zwangs-Covid-«Impfung» bewahrt nicht vor dem Knast, wie Bundeswehrsoldaten wie Alexander Bittner erfahren mussten.
Die eigentlich Kriminellen schützen sich derweil erfolgreich selber, nämlich vor der Verantwortung. Die «Impf»-Kampagne war «das größte Verbrechen gegen die Menschheit». Trotzdem stellt man sich in den USA gerade die Frage, ob der scheidende Präsident Joe Biden nach seinem Sohn Hunter möglicherweise auch Anthony Fauci begnadigen wird – in diesem Fall sogar präventiv. Gibt es überhaupt noch einen Rest Glaubwürdigkeit, den Biden verspielen könnte?
Der Gedanke, den ehemaligen wissenschaftlichen Chefberater des US-Präsidenten und Direktor des National Institute of Allergy and Infectious Diseases (NIAID) vorsorglich mit einem Schutzschild zu versehen, dürfte mit der vergangenen Präsidentschaftswahl zu tun haben. Gleich mehrere Personalentscheidungen des designierten Präsidenten Donald Trump lassen Leute wie Fauci erneut in den Fokus rücken.
Das Buch «The Real Anthony Fauci» des nominierten US-Gesundheitsministers Robert F. Kennedy Jr. erschien 2021 und dreht sich um die Machenschaften der Pharma-Lobby in der öffentlichen Gesundheit. Das Vorwort zur rumänischen Ausgabe des Buches schrieb übrigens Călin Georgescu, der Überraschungssieger der ersten Wahlrunde der aktuellen Präsidentschaftswahlen in Rumänien. Vielleicht erklärt diese Verbindung einen Teil der Panik im Wertewesten.
In Rumänien selber gab es gerade einen Paukenschlag: Das bisherige Ergebnis wurde heute durch das Verfassungsgericht annuliert und die für Sonntag angesetzte Stichwahl kurzfristig abgesagt – wegen angeblicher «aggressiver russischer Einmischung». Thomas Oysmüller merkt dazu an, damit sei jetzt in der EU das Tabu gebrochen, Wahlen zu verbieten, bevor sie etwas ändern können.
Unsere Empörung angesichts der Historie von Maßnahmen, die die Falschen beschützen und für die meisten von Nachteil sind, müsste enorm sein. Die Frage ist, was wir damit machen. Wir sollten nach vorne schauen und unsere Energie clever einsetzen. Abgesehen von der Umgehung von jeglichem «Schutz vor Desinformation und Hassrede» (sprich: Zensur) wird es unsere wichtigste Aufgabe sein, Gräben zu überwinden.

2024-11-18 20:26:07Chef's notes
This simple, easy, no bake desert will surely be the it at you next family gathering. You can keep it a secret or share it with the crowd that this is a healthy alternative to normal pie. I think everyone will be amazed at how good it really is.
Details
- ⏲️ Prep time: 30
- 🍳 Cook time: 0
- 🍽️ Servings: 8
Ingredients
- 1/3 cup of Heavy Cream- 0g sugar, 5.5g carbohydrates
- 3/4 cup of Half and Half- 6g sugar, 3g carbohydrates
- 4oz Sugar Free Cool Whip (1/2 small container) - 0g sugar, 37.5g carbohydrates
- 1.5oz box (small box) of Sugar Free Instant Chocolate Pudding- 0g sugar, 32g carbohydrates
- 1 Pecan Pie Crust- 24g sugar, 72g carbohydrates
Directions
- The total pie has 30g of sugar and 149.50g of carboydrates. So if you cut the pie into 8 equal slices, that would come to 3.75g of sugar and 18.69g carbohydrates per slice. If you decided to not eat the crust, your sugar intake would be .75 gram per slice and the carborytrates would be 9.69g per slice. Based on your objective, you could use only heavy whipping cream and no half and half to further reduce your sugar intake.
- Mix all wet ingredients and the instant pudding until thoroughly mixed and a consistent color has been achieved. The heavy whipping cream causes the mixture to thicken the more you mix it. So, I’d recommend using an electric mixer. Once you are satisfied with the color, start mixing in the whipping cream until it has a consistent “chocolate” color thorough. Once your satisfied with the color, spoon the mixture into the pie crust, smooth the top to your liking, and then refrigerate for one hour before serving.

2024-11-29 19:45:43Konsum ist Therapie.
Wolfgang JoopUmweltbewusstes Verhalten und verantwortungsvoller Konsum zeugen durchaus von einer wünschenswerten Einstellung. Ob man deswegen allerdings einen grünen statt eines schwarzen Freitags braucht, darf getrost bezweifelt werden – zumal es sich um manipulatorische Konzepte handelt. Wie in der politischen Landschaft sind auch hier die Etiketten irgendwas zwischen nichtssagend und trügerisch.
Heute ist also wieder mal «Black Friday», falls Sie es noch nicht mitbekommen haben sollten. Eigentlich haben wir ja eher schon eine ganze «Black Week», der dann oft auch noch ein «Cyber Monday» folgt. Die Werbebranche wird nicht müde, immer neue Anlässe zu erfinden oder zu importieren, um uns zum Konsumieren zu bewegen. Und sie ist damit sehr erfolgreich.
Warum fallen wir auf derartige Werbetricks herein und kaufen im Zweifelsfall Dinge oder Mengen, die wir sicher nicht brauchen? Pure Psychologie, würde ich sagen. Rabattschilder triggern etwas in uns, was den Verstand in Stand-by versetzt. Zusätzlich beeinflussen uns alle möglichen emotionalen Reize und animieren uns zum Schnäppchenkauf.
Gedankenlosigkeit und Maßlosigkeit können besonders bei der Ernährung zu ernsten Problemen führen. Erst kürzlich hat mir ein Bekannter nach einer USA-Reise erzählt, dass es dort offenbar nicht unüblich ist, schon zum ausgiebigen Frühstück in einem Restaurant wenigstens einen Liter Cola zu trinken. Gerne auch mehr, um das Gratis-Nachfüllen des Bechers auszunutzen.
Kritik am schwarzen Freitag und dem unnötigen Konsum kommt oft von Umweltschützern. Neben Ressourcenverschwendung, hohem Energieverbrauch und wachsenden Müllbergen durch eine zunehmende Wegwerfmentalität kommt dabei in der Regel auch die «Klimakrise» auf den Tisch.
Die EU-Kommission lancierte 2015 den Begriff «Green Friday» im Kontext der überarbeiteten Rechtsvorschriften zur Kennzeichnung der Energieeffizienz von Elektrogeräten. Sie nutzte die Gelegenheit kurz vor dem damaligen schwarzen Freitag und vor der UN-Klimakonferenz COP21, bei der das Pariser Abkommen unterzeichnet werden sollte.
Heute wird ein grüner Freitag oft im Zusammenhang mit der Forderung nach «nachhaltigem Konsum» benutzt. Derweil ist die Europäische Union schon weit in ihr Geschäftsmodell des «Green New Deal» verstrickt. In ihrer Propaganda zum Klimawandel verspricht sie tatsächlich «Unterstützung der Menschen und Regionen, die von immer häufigeren Extremwetter-Ereignissen betroffen sind». Was wohl die Menschen in der Region um Valencia dazu sagen?
Ganz im Sinne des Great Reset propagierten die Vereinten Nationen seit Ende 2020 eine «grüne Erholung von Covid-19, um den Klimawandel zu verlangsamen». Der UN-Umweltbericht sah in dem Jahr einen Schwerpunkt auf dem Verbraucherverhalten. Änderungen des Konsumverhaltens des Einzelnen könnten dazu beitragen, den Klimaschutz zu stärken, hieß es dort.
Der Begriff «Schwarzer Freitag» wurde in den USA nicht erstmals für Einkäufe nach Thanksgiving verwendet – wie oft angenommen –, sondern für eine Finanzkrise. Jedoch nicht für den Börsencrash von 1929, sondern bereits für den Zusammenbruch des US-Goldmarktes im September 1869. Seitdem mussten die Menschen weltweit so einige schwarze Tage erleben.
Kürzlich sind die britischen Aufsichtsbehörden weiter von ihrer Zurückhaltung nach dem letzten großen Finanzcrash von 2008 abgerückt. Sie haben Regeln für den Bankensektor gelockert, womit sie «verantwortungsvolle Risikobereitschaft» unterstützen wollen. Man würde sicher zu schwarz sehen, wenn man hier ein grünes Wunder befürchten würde.

2024-11-17 17:33:55Let me tell you a beautiful story. Last night, during the speakers' dinner at Monerotopia, the waitress was collecting tiny tips in Mexican pesos. I asked her, "Do you really want to earn tips seriously?" I then showed her how to set up a Cake Wallet, and she started collecting tips in Monero, reaching 0.9 XMR. Of course, she wanted to cash out to fiat immediately, but it solved a real problem for her: making more money. That amount was something she would never have earned in a single workday. We kept talking, and I promised to give her Zoom workshops. What can I say? I love people, and that's why I'm a natural orange-piller.

2024-11-08 20:02:32Und plötzlich weißt du:
Es ist Zeit, etwas Neues zu beginnen
und dem Zauber des Anfangs zu vertrauen.
Meister EckhartSchwarz, rot, gold leuchtet es im Kopf des Newsletters der deutschen Bundesregierung, der mir freitags ins Postfach flattert. Rot, gelb und grün werden daneben sicher noch lange vielzitierte Farben sein, auch wenn diese nie geleuchtet haben. Die Ampel hat sich gerade selber den Stecker gezogen – und hinterlässt einen wirtschaftlichen und gesellschaftlichen Trümmerhaufen.
Mit einem bemerkenswerten Timing hat die deutsche Regierungskoalition am Tag des «Comebacks» von Donald Trump in den USA endlich ihr Scheitern besiegelt. Während der eine seinen Sieg bei den Präsidentschaftswahlen feierte, erwachten die anderen jäh aus ihrer Selbsthypnose rund um Harris-Hype und Trump-Panik – mit teils erschreckenden Auswüchsen. Seit Mittwoch werden die Geschicke Deutschlands nun von einer rot-grünen Minderheitsregierung «geleitet» und man steuert auf Neuwahlen zu.
Das Kindergarten-Gehabe um zwei konkurrierende Wirtschaftsgipfel letzte Woche war bereits bezeichnend. In einem Strategiepapier gestand Finanzminister Lindner außerdem den «Absturz Deutschlands» ein und offenbarte, dass die wirtschaftlichen Probleme teilweise von der Ampel-Politik «vorsätzlich herbeigeführt» worden seien.
Lindner und weitere FDP-Minister wurden also vom Bundeskanzler entlassen. Verkehrs- und Digitalminister Wissing trat flugs aus der FDP aus; deshalb darf er nicht nur im Amt bleiben, sondern hat zusätzlich noch das Justizministerium übernommen. Und mit Jörg Kukies habe Scholz «seinen Lieblingsbock zum Obergärtner», sprich: Finanzminister befördert, meint Norbert Häring.
Es gebe keine Vertrauensbasis für die weitere Zusammenarbeit mit der FDP, hatte der Kanzler erklärt, Lindner habe zu oft sein Vertrauen gebrochen. Am 15. Januar 2025 werde er daher im Bundestag die Vertrauensfrage stellen, was ggf. den Weg für vorgezogene Neuwahlen freimachen würde.
Apropos Vertrauen: Über die Hälfte der Bundesbürger glauben, dass sie ihre Meinung nicht frei sagen können. Das ging erst kürzlich aus dem diesjährigen «Freiheitsindex» hervor, einer Studie, die die Wechselwirkung zwischen Berichterstattung der Medien und subjektivem Freiheitsempfinden der Bürger misst. «Beim Vertrauen in Staat und Medien zerreißt es uns gerade», kommentierte dies der Leiter des Schweizer Unternehmens Media Tenor, das die Untersuchung zusammen mit dem Institut für Demoskopie Allensbach durchführt.
«Die absolute Mehrheit hat absolut die Nase voll», titelte die Bild angesichts des «Ampel-Showdowns». Die Mehrheit wolle Neuwahlen und die Grünen sollten zuerst gehen, lasen wir dort.
Dass «Insolvenzminister» Robert Habeck heute seine Kandidatur für das Kanzleramt verkündet hat, kann nur als Teil der politmedialen Realitätsverweigerung verstanden werden. Wer allerdings denke, schlimmer als in Zeiten der Ampel könne es nicht mehr werden, sei reichlich optimistisch, schrieb Uwe Froschauer bei Manova. Und er kenne Friedrich Merz schlecht, der sich schon jetzt rhetorisch auf seine Rolle als oberster Feldherr Deutschlands vorbereite.
Was also tun? Der Schweizer Verein «Losdemokratie» will eine Volksinitiative lancieren, um die Bestimmung von Parlamentsmitgliedern per Los einzuführen. Das Losverfahren sorge für mehr Demokratie, denn als Alternative zum Wahlverfahren garantiere es eine breitere Beteiligung und repräsentativere Parlamente. Ob das ein Weg ist, sei dahingestellt.
In jedem Fall wird es notwendig sein, unsere Bemühungen um Freiheit und Selbstbestimmung zu verstärken. Mehr Unabhängigkeit von staatlichen und zentralen Institutionen – also die Suche nach dezentralen Lösungsansätzen – gehört dabei sicher zu den Möglichkeiten. Das gilt sowohl für jede/n Einzelne/n als auch für Entitäten wie die alternativen Medien.

Quando o assunto é privacidade em celulares, uma das medidas comumente mencionadas é a remoção de bloatwares do dispositivo, também chamado de debloat. O meio mais eficiente para isso sem dúvidas é a troca de sistema operacional. Custom Rom’s como LineageOS, GrapheneOS, Iodé, CalyxOS, etc, já são bastante enxutos nesse quesito, principalmente quanto não é instalado os G-Apps com o sistema. No entanto, essa prática pode acabar resultando em problemas indesejados como a perca de funções do dispositivo, e até mesmo incompatibilidade com apps bancários, tornando este método mais atrativo para quem possui mais de um dispositivo e separando um apenas para privacidade. Pensando nisso, pessoas que possuem apenas um único dispositivo móvel, que são necessitadas desses apps ou funções, mas, ao mesmo tempo, tem essa visão em prol da privacidade, buscam por um meio-termo entre manter a Stock rom, e não ter seus dados coletados por esses bloatwares. Felizmente, a remoção de bloatwares é possível e pode ser realizada via root, ou mais da maneira que este artigo irá tratar, via adb.
O que são bloatwares?
Bloatware é a junção das palavras bloat (inchar) + software (programa), ou seja, um bloatware é basicamente um programa inútil ou facilmente substituível — colocado em seu dispositivo previamente pela fabricante e operadora — que está no seu dispositivo apenas ocupando espaço de armazenamento, consumindo memória RAM e pior, coletando seus dados e enviando para servidores externos, além de serem mais pontos de vulnerabilidades.
O que é o adb?
O Android Debug Brigde, ou apenas adb, é uma ferramenta que se utiliza das permissões de usuário shell e permite o envio de comandos vindo de um computador para um dispositivo Android exigindo apenas que a depuração USB esteja ativa, mas também pode ser usada diretamente no celular a partir do Android 11, com o uso do Termux e a depuração sem fio (ou depuração wifi). A ferramenta funciona normalmente em dispositivos sem root, e também funciona caso o celular esteja em Recovery Mode.
Requisitos:
Para computadores:
• Depuração USB ativa no celular; • Computador com adb; • Cabo USB;
Para celulares:
• Depuração sem fio (ou depuração wifi) ativa no celular; • Termux; • Android 11 ou superior;
Para ambos:
• Firewall NetGuard instalado e configurado no celular; • Lista de bloatwares para seu dispositivo;
Ativação de depuração:
Para ativar a Depuração USB em seu dispositivo, pesquise como ativar as opções de desenvolvedor de seu dispositivo, e lá ative a depuração. No caso da depuração sem fio, sua ativação irá ser necessária apenas no momento que for conectar o dispositivo ao Termux.
Instalação e configuração do NetGuard
O NetGuard pode ser instalado através da própria Google Play Store, mas de preferência instale pela F-Droid ou Github para evitar telemetria.
F-Droid: https://f-droid.org/packages/eu.faircode.netguard/
Github: https://github.com/M66B/NetGuard/releases
Após instalado, configure da seguinte maneira:
Configurações → padrões (lista branca/negra) → ative as 3 primeiras opções (bloquear wifi, bloquear dados móveis e aplicar regras ‘quando tela estiver ligada’);
Configurações → opções avançadas → ative as duas primeiras (administrar aplicativos do sistema e registrar acesso a internet);
Com isso, todos os apps estarão sendo bloqueados de acessar a internet, seja por wifi ou dados móveis, e na página principal do app basta permitir o acesso a rede para os apps que você vai usar (se necessário). Permita que o app rode em segundo plano sem restrição da otimização de bateria, assim quando o celular ligar, ele já estará ativo.
Lista de bloatwares
Nem todos os bloatwares são genéricos, haverá bloatwares diferentes conforme a marca, modelo, versão do Android, e até mesmo região.
Para obter uma lista de bloatwares de seu dispositivo, caso seu aparelho já possua um tempo de existência, você encontrará listas prontas facilmente apenas pesquisando por elas. Supondo que temos um Samsung Galaxy Note 10 Plus em mãos, basta pesquisar em seu motor de busca por:
Samsung Galaxy Note 10 Plus bloatware list
Provavelmente essas listas já terão inclusas todos os bloatwares das mais diversas regiões, lhe poupando o trabalho de buscar por alguma lista mais específica.
Caso seu aparelho seja muito recente, e/ou não encontre uma lista pronta de bloatwares, devo dizer que você acaba de pegar em merda, pois é chato para um caralho pesquisar por cada aplicação para saber sua função, se é essencial para o sistema ou se é facilmente substituível.
De antemão já aviso, que mais para frente, caso vossa gostosura remova um desses aplicativos que era essencial para o sistema sem saber, vai acabar resultando na perda de alguma função importante, ou pior, ao reiniciar o aparelho o sistema pode estar quebrado, lhe obrigando a seguir com uma formatação, e repetir todo o processo novamente.
Download do adb em computadores
Para usar a ferramenta do adb em computadores, basta baixar o pacote chamado SDK platform-tools, disponível através deste link: https://developer.android.com/tools/releases/platform-tools. Por ele, você consegue o download para Windows, Mac e Linux.
Uma vez baixado, basta extrair o arquivo zipado, contendo dentro dele uma pasta chamada platform-tools que basta ser aberta no terminal para se usar o adb.
Download do adb em celulares com Termux.
Para usar a ferramenta do adb diretamente no celular, antes temos que baixar o app Termux, que é um emulador de terminal linux, e já possui o adb em seu repositório. Você encontra o app na Google Play Store, mas novamente recomendo baixar pela F-Droid ou diretamente no Github do projeto.
F-Droid: https://f-droid.org/en/packages/com.termux/
Github: https://github.com/termux/termux-app/releases
Processo de debloat
Antes de iniciarmos, é importante deixar claro que não é para você sair removendo todos os bloatwares de cara sem mais nem menos, afinal alguns deles precisam antes ser substituídos, podem ser essenciais para você para alguma atividade ou função, ou até mesmo são insubstituíveis.
Alguns exemplos de bloatwares que a substituição é necessária antes da remoção, é o Launcher, afinal, é a interface gráfica do sistema, e o teclado, que sem ele só é possível digitar com teclado externo. O Launcher e teclado podem ser substituídos por quaisquer outros, minha recomendação pessoal é por aqueles que respeitam sua privacidade, como Pie Launcher e Simple Laucher, enquanto o teclado pelo OpenBoard e FlorisBoard, todos open-source e disponíveis da F-Droid.
Identifique entre a lista de bloatwares, quais você gosta, precisa ou prefere não substituir, de maneira alguma você é obrigado a remover todos os bloatwares possíveis, modifique seu sistema a seu bel-prazer. O NetGuard lista todos os apps do celular com o nome do pacote, com isso você pode filtrar bem qual deles não remover.
Um exemplo claro de bloatware insubstituível e, portanto, não pode ser removido, é o com.android.mtp, um protocolo onde sua função é auxiliar a comunicação do dispositivo com um computador via USB, mas por algum motivo, tem acesso a rede e se comunica frequentemente com servidores externos. Para esses casos, e melhor solução mesmo é bloquear o acesso a rede desses bloatwares com o NetGuard.
MTP tentando comunicação com servidores externos:
Executando o adb shell
No computador
Faça backup de todos os seus arquivos importantes para algum armazenamento externo, e formate seu celular com o hard reset. Após a formatação, e a ativação da depuração USB, conecte seu aparelho e o pc com o auxílio de um cabo USB. Muito provavelmente seu dispositivo irá apenas começar a carregar, por isso permita a transferência de dados, para que o computador consiga se comunicar normalmente com o celular.
Já no pc, abra a pasta platform-tools dentro do terminal, e execute o seguinte comando:
./adb start-server
O resultado deve ser:
daemon not running; starting now at tcp:5037 daemon started successfully
E caso não apareça nada, execute:
./adb kill-server
E inicie novamente.
Com o adb conectado ao celular, execute:
./adb shell
Para poder executar comandos diretamente para o dispositivo. No meu caso, meu celular é um Redmi Note 8 Pro, codinome Begonia.
Logo o resultado deve ser:
begonia:/ $
Caso ocorra algum erro do tipo:
adb: device unauthorized. This adb server’s $ADB_VENDOR_KEYS is not set Try ‘adb kill-server’ if that seems wrong. Otherwise check for a confirmation dialog on your device.
Verifique no celular se apareceu alguma confirmação para autorizar a depuração USB, caso sim, autorize e tente novamente. Caso não apareça nada, execute o kill-server e repita o processo.
No celular
Após realizar o mesmo processo de backup e hard reset citado anteriormente, instale o Termux e, com ele iniciado, execute o comando:
pkg install android-tools
Quando surgir a mensagem “Do you want to continue? [Y/n]”, basta dar enter novamente que já aceita e finaliza a instalação
Agora, vá até as opções de desenvolvedor, e ative a depuração sem fio. Dentro das opções da depuração sem fio, terá uma opção de emparelhamento do dispositivo com um código, que irá informar para você um código em emparelhamento, com um endereço IP e porta, que será usado para a conexão com o Termux.
Para facilitar o processo, recomendo que abra tanto as configurações quanto o Termux ao mesmo tempo, e divida a tela com os dois app’s, como da maneira a seguir:
Para parear o Termux com o dispositivo, não é necessário digitar o ip informado, basta trocar por “localhost”, já a porta e o código de emparelhamento, deve ser digitado exatamente como informado. Execute:
adb pair localhost:porta CódigoDeEmparelhamento
De acordo com a imagem mostrada anteriormente, o comando ficaria “adb pair localhost:41255 757495”.
Com o dispositivo emparelhado com o Termux, agora basta conectar para conseguir executar os comandos, para isso execute:
adb connect localhost:porta
Obs: a porta que você deve informar neste comando não é a mesma informada com o código de emparelhamento, e sim a informada na tela principal da depuração sem fio.
Pronto! Termux e adb conectado com sucesso ao dispositivo, agora basta executar normalmente o adb shell:
adb shell
Remoção na prática Com o adb shell executado, você está pronto para remover os bloatwares. No meu caso, irei mostrar apenas a remoção de um app (Google Maps), já que o comando é o mesmo para qualquer outro, mudando apenas o nome do pacote.
Dentro do NetGuard, verificando as informações do Google Maps:
Podemos ver que mesmo fora de uso, e com a localização do dispositivo desativado, o app está tentando loucamente se comunicar com servidores externos, e informar sabe-se lá que peste. Mas sem novidades até aqui, o mais importante é que podemos ver que o nome do pacote do Google Maps é com.google.android.apps.maps, e para o remover do celular, basta executar:
pm uninstall –user 0 com.google.android.apps.maps
E pronto, bloatware removido! Agora basta repetir o processo para o resto dos bloatwares, trocando apenas o nome do pacote.
Para acelerar o processo, você pode já criar uma lista do bloco de notas com os comandos, e quando colar no terminal, irá executar um atrás do outro.
Exemplo de lista:
Caso a donzela tenha removido alguma coisa sem querer, também é possível recuperar o pacote com o comando:
cmd package install-existing nome.do.pacote
Pós-debloat
Após limpar o máximo possível o seu sistema, reinicie o aparelho, caso entre no como recovery e não seja possível dar reboot, significa que você removeu algum app “essencial” para o sistema, e terá que formatar o aparelho e repetir toda a remoção novamente, desta vez removendo poucos bloatwares de uma vez, e reiniciando o aparelho até descobrir qual deles não pode ser removido. Sim, dá trabalho… quem mandou querer privacidade?
Caso o aparelho reinicie normalmente após a remoção, parabéns, agora basta usar seu celular como bem entender! Mantenha o NetGuard sempre executando e os bloatwares que não foram possíveis remover não irão se comunicar com servidores externos, passe a usar apps open source da F-Droid e instale outros apps através da Aurora Store ao invés da Google Play Store.

2024-11-08 08:08:30You have no idea
I regularly read comments from people, on here, wondering how it's possible to marry -- or even simply be friends! -- with someone who doesn't agree with you on politics. I see this sentiment expressed quite often, usually in the context of Bitcoin, or whatever pig is currently being chased through the village, as they say around here.
It seems rather sensible, but I don't think it's as hard, as people make it out to be. Further, I think it's a dangerous precondition to set, for your interpersonal relationships, because the political field is constantly in flux. If you determine who you will love, by their opinions, do you stop loving them if their opinions change, or if the opinions they have become irrelevant and a new set of opinions are needed -- and their new ones don't match your new ones? We could see this happen to relationships en masse, during the Covid Era, and I think it happens every day, in a slow grind toward the disintegration of interpersonal discourse.
I suspect many people do stop loving, at that point, as they never really loved the other person for their own sake, they loved the other person because they thought the other person was exactly like they are. But no two people are alike, and the longer you are in a relationship with someone else, the more the initial giddiness wears off and the trials and tribulations add up, the more you notice how very different you actually are. This is the point, where best friends and romantic couples say, We just grew apart.
But you were always apart. You were always two different people. You just didn't notice, until now.
I've also always been surprised at how many same-party relationships disintegrate because of some disagreement over some particular detail of some particular topic, that they generally agree on. To me, it seems like an irrelevant side-topic, but they can't stand to be with this person... and they stomp off. So, I tend to think that it's less that opinions need to align to each other, but rather than opinions need to align in accordance with the level of interpersonal tolerance they can bring into the relationship.
I was raised by relaxed revolutionaries
Maybe I see things this way because my parents come from two diverging political, cultural, national, and ethnic backgrounds, and are prone to disagreeing about a lot of "important" (to people outside their marriage) things, but still have one of the healthiest, most-fruitful, and most long-running marriages of anyone I know, from that generation. My parents, you see, aren't united by their opinions. They're united by their relationship, which is something outside of opinions. Beyond opinions. Relationships are what turn two different people into one, cohesive unit, so that they slowly grow together. Eventually, even their faces merge, and their biological clocks tick to the same rhythm. They eventually become one entity that contains differing opinions about the same topics.
It's like magic, but it's the result of a mindset, not a worldview. Or, as I like to quip:
The best way to stay married, is to not get divorced.
My parents simply determined early on, that they would stay together, and whenever they would find that they disagreed on something that didn't directly pertain to their day-to-day existence with each other they would just agree-to-disagree about that, or roll their eyes, and move on. You do you. Live and let live.
My parents have some of the most strongly held personal opinions of any people I've ever met, but they're also incredibly tolerant and can get along with nearly anyone, so their friends are a confusing hodgepodge of people we liked and found interesting enough to keep around. Which makes their house parties really fun, and highly unusual, in this day and age of mutual-damnation across the aisle.
The things that did affect them, directly, like which school the children should attend or which country they should live in, etc. were things they'd sit down and discuss, and somehow one opinion would emerge, and they'd again... move on.
And that's how my husband and I also live our lives, and it's been working surprisingly well. No topics are off-limits to discussion (so long as you don't drone on for too long), nobody has to give up deeply held beliefs, or stop agitating for the political decisions they prefer.
You see, we didn't like that the other always had the same opinion. We liked that the other always held their opinions strongly. That they were passionate about their opinions. That they were willing to voice their opinions; sacrifice to promote their opinions. And that they didn't let anyone browbeat or cow them, for their opinions, not even their best friends or their spouse. But that they were open to listening to the other side, and trying to wrap their mind around the possibility that they might just be wrong about something.
We married each other because we knew: this person really cares, this person has thought this through, and they're in it, to win it. What "it" is, is mostly irrelevant, so long as it doesn't entail torturing small animals in the basement, or raising the children on a diet of Mountain Dew and porn, or something.
Live and let live. At least, it's never boring. At least, there's always something to ~~argue~~ talk about. At least, we never think... we've just grown apart.

2024-10-26 12:21:50Es ist besser, ein Licht zu entzünden, als auf die Dunkelheit zu schimpfen. Konfuzius
Die Bemühungen um Aufarbeitung der sogenannten Corona-Pandemie, um Aufklärung der Hintergründe, Benennung von Verantwortlichkeiten und das Ziehen von Konsequenzen sind durchaus nicht eingeschlafen. Das Interesse daran ist unter den gegebenen Umständen vielleicht nicht sonderlich groß, aber es ist vorhanden.
Der sächsische Landtag hat gestern die Einsetzung eines Untersuchungsausschusses zur Corona-Politik beschlossen. In einer Sondersitzung erhielt ein entsprechender Antrag der AfD-Fraktion die ausreichende Zustimmung, auch von einigen Abgeordneten des BSW.
In den Niederlanden wird Bill Gates vor Gericht erscheinen müssen. Sieben durch die Covid-«Impfstoffe» geschädigte Personen hatten Klage eingereicht. Sie werfen unter anderem Gates, Pfizer-Chef Bourla und dem niederländischen Staat vor, sie hätten gewusst, dass diese Präparate weder sicher noch wirksam sind.
Mit den mRNA-«Impfstoffen» von Pfizer/BioNTech befasst sich auch ein neues Buch. Darin werden die Erkenntnisse von Ärzten und Wissenschaftlern aus der Analyse interner Dokumente über die klinischen Studien der Covid-Injektion präsentiert. Es handelt sich um jene in den USA freigeklagten Papiere, die die Arzneimittelbehörde (Food and Drug Administration, FDA) 75 Jahre unter Verschluss halten wollte.
Ebenfalls Wissenschaftler und Ärzte, aber auch andere Experten organisieren als Verbundnetzwerk Corona-Solution kostenfreie Online-Konferenzen. Ihr Ziel ist es, «wissenschaftlich, demokratisch und friedlich» über Impfstoffe und Behandlungsprotokolle gegen SARS-CoV-2 aufzuklären und die Diskriminierung von Ungeimpften zu stoppen. Gestern fand eine weitere Konferenz statt. Ihr Thema: «Corona und modRNA: Von Toten, Lebenden und Physik lernen».
Aufgrund des Digital Services Acts (DSA) der Europäischen Union sei das Risiko groß, dass ihre Arbeit als «Fake-News» bezeichnet würde, so das Netzwerk. Staatlich unerwünschte wissenschaftliche Aufklärung müsse sich passende Kanäle zur Veröffentlichung suchen. Ihre Live-Streams seien deshalb zum Beispiel nicht auf YouTube zu finden.
Der vielfältige Einsatz für Aufklärung und Aufarbeitung wird sich nicht stummschalten lassen. Nicht einmal der Zensurmeister der EU, Deutschland, wird so etwas erreichen. Die frisch aktivierten «Trusted Flagger» dürften allerdings künftige Siege beim «Denunzianten-Wettbewerb» im Kontext des DSA zusätzlich absichern.
Wo sind die Grenzen der Meinungsfreiheit? Sicher gibt es sie. Aber die ideologische Gleichstellung von illegalen mit unerwünschten Äußerungen verfolgt offensichtlich eher das Ziel, ein derart elementares demokratisches Grundrecht möglichst weitgehend auszuhebeln. Vorwürfe wie «Hassrede», «Delegitimierung des Staates» oder «Volksverhetzung» werden heute inflationär verwendet, um Systemkritik zu unterbinden. Gegen solche Bestrebungen gilt es, sich zu wehren.

2025-03-01 20:37:31Alright, Fast February has come to an end. It was more impactful than I anticipated, considering daily intermittent dry fasting had been part of my routine for a long time.
I had definitely let the practice slip to the point where I probably wasn't regularly entering ketosis. Now, my food cravings are substantially reduced and it's quite easy for me to confine my eating to a smaller window.
Even with the fiscal fast being over, I just bought some vitamins and coconut milk (no cravings for junk food or snacks). I would have gotten some fruit, too, but it didn't look great. I did notice craving more juicy foods this month, as my dry fasts got longer. Eating more fruit will probably be an adjustment I make going forward.
If you have any practices that have been on autopilot, I recommend occasionally putting some focus on them to make sure they're still doing what you thought they were.

2024-10-23 20:26:10Herzlichen Glückwunsch zum dritten Geburtstag, liebe Denk Bar! Wieso zum dritten? Das war doch 2022 und jetzt sind wir im Jahr 2024, oder? Ja, das ist schon richtig, aber bei Geburtstagen erinnere ich mich immer auch an meinen Vater, und der behauptete oft, der erste sei ja schließlich der Tag der Geburt selber und den müsse man natürlich mitzählen. Wo er recht hat, hat er nunmal recht. Konsequenterweise wird also heute dieser Blog an seinem dritten Geburtstag zwei Jahre alt.
Das ist ein Grund zum Feiern, wie ich finde. Einerseits ganz einfach, weil es dafür gar nicht genug Gründe geben kann. «Das Leben sind zwei Tage», lautet ein gängiger Ausdruck hier in Andalusien. In der Tat könnte es so sein, auch wenn wir uns im Alltag oft genug von der Routine vereinnahmen lassen.
Seit dem Start der Denk Bar vor zwei Jahren ist unglaublich viel passiert. Ebenso wie die zweieinhalb Jahre davor, und all jenes war letztlich auch der Auslöser dafür, dass ich begann, öffentlich zu schreiben. Damals notierte ich:
«Seit einigen Jahren erscheint unser öffentliches Umfeld immer fragwürdiger, widersprüchlicher und manchmal schier unglaublich - jede Menge Anlass für eigene Recherchen und Gedanken, ganz einfach mit einer Portion gesundem Menschenverstand.»
Wir erleben den sogenannten «großen Umbruch», einen globalen Coup, den skrupellose Egoisten clever eingefädelt haben und seit ein paar Jahren knallhart – aber nett verpackt – durchziehen, um buchstäblich alles nach ihrem Gusto umzukrempeln. Die Gelegenheit ist ja angeblich günstig und muss genutzt werden.
Nie hätte ich mir träumen lassen, dass ich so etwas jemals miterleben müsste. Die Bosheit, mit der ganz offensichtlich gegen die eigene Bevölkerung gearbeitet wird, war früher für mich unvorstellbar. Mein (Rest-) Vertrauen in alle möglichen Bereiche wie Politik, Wissenschaft, Justiz, Medien oder Kirche ist praktisch komplett zerstört. Einen «inneren Totalschaden» hatte ich mal für unsere Gesellschaften diagnostiziert.
Was mich vielleicht am meisten erschreckt, ist zum einen das Niveau der Gleichschaltung, das weltweit erreicht werden konnte, und zum anderen die praktisch totale Spaltung der Gesellschaft. Haben wir das tatsächlich mit uns machen lassen?? Unfassbar! Aber das Werkzeug «Angst» ist sehr mächtig und funktioniert bis heute.
Zum Glück passieren auch positive Dinge und neue Perspektiven öffnen sich. Für viele Menschen waren und sind die Entwicklungen der letzten Jahre ein Augenöffner. Sie sehen «Querdenken» als das, was es ist: eine Tugend.
Auch die immer ernsteren Zensurbemühungen sind letztlich nur ein Zeichen der Schwäche, wo Argumente fehlen. Sie werden nicht verhindern, dass wir unsere Meinung äußern, unbequeme Fragen stellen und dass die Wahrheit peu à peu ans Licht kommt. Es gibt immer Mittel und Wege, auch für uns.
Danke, dass du diesen Weg mit mir weitergehst!

2024-10-19 08:58:08Ein Lämmchen löschte an einem Bache seinen Durst. Fern von ihm, aber näher der Quelle, tat ein Wolf das gleiche. Kaum erblickte er das Lämmchen, so schrie er:
"Warum trübst du mir das Wasser, das ich trinken will?"
"Wie wäre das möglich", erwiderte schüchtern das Lämmchen, "ich stehe hier unten und du so weit oben; das Wasser fließt ja von dir zu mir; glaube mir, es kam mir nie in den Sinn, dir etwas Böses zu tun!"
"Ei, sieh doch! Du machst es gerade, wie dein Vater vor sechs Monaten; ich erinnere mich noch sehr wohl, daß auch du dabei warst, aber glücklich entkamst, als ich ihm für sein Schmähen das Fell abzog!"
"Ach, Herr!" flehte das zitternde Lämmchen, "ich bin ja erst vier Wochen alt und kannte meinen Vater gar nicht, so lange ist er schon tot; wie soll ich denn für ihn büßen."
"Du Unverschämter!" so endigt der Wolf mit erheuchelter Wut, indem er die Zähne fletschte. "Tot oder nicht tot, weiß ich doch, daß euer ganzes Geschlecht mich hasset, und dafür muß ich mich rächen."
Ohne weitere Umstände zu machen, zerriß er das Lämmchen und verschlang es.
Das Gewissen regt sich selbst bei dem größten Bösewichte; er sucht doch nach Vorwand, um dasselbe damit bei Begehung seiner Schlechtigkeiten zu beschwichtigen.

Bom dia/tarde/noite a todos os camaradas. Seguindo a nossa série de tutoriais referentes a tecnologias essenciais para a segurança e o anonimato dos usuários, sendo as primeiras a openPGP e a I2P, lhes apresento mais uma opção para expandir os seus conhecimentos da DW. Muitos devem conhecer os serviços de mail na onion como DNMX e mail2tor, mas e que tal um serviço de email pela I2P. Nesse tutorial eu vou mostrar a vocês como criar a sua primeira conta no hq.postman.i2p e a acessar essa conta.
É importante que vocês tenham lido a minha primeira série de tutoriais a respeito de como instalar, configurar e navegar pela I2P nostr:nevent1qqsyjcz2w0e6d6dcdeprhuuarw4aqkw730y542dzlwxwssneq3mwpaspz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsygzt4r5x6tvh39kujvmu8egqdyvf84e3w4e0mq0ckswamfwcn5eduspsgqqqqqqsyp5vcq Esse tutorial é um pré-requisito para o seguinte e portanto recomendo que leia-os antes de prosseguir com o seguinte tutorial. O tutorial de Kleopatra nostr:nevent1qqs8h7vsn5j6qh35949sa60dms4fneussmv9jd76n24lsmtz24k0xlqzyp9636rd9ktcjmwfxd7ru5qxjxyn6uch2uhas8utg8wa5hvf6vk7gqcyqqqqqqgecq8f7 é complementar dado que é extremamente recomendado assinar e criptografar as mensagens que seguem por emails pela DW. Sem mais delongas, vamos ao tutorial de fato.
1. Criando uma conta de email no hq.postman
Relembrando: Esse tutorial considera que você já tenha acesso à I2P. Entre no seu navegador e acesse o endereço hq.postman.i2p. O roteador provavelmente já contém esse endereço no seu addressbook e não haverá a necessidade de inserir o endereço b32 completo. Após entrar no site vá para a página '1 - Creating a mailbox' https://image.nostr.build/d850379fe315d2abab71430949b06d3fa49366d91df4c9b00a4a8367d53fcca3.jpg
Nessa página, insira as credenciais de sua preferências nos campos do formulário abaixo. Lembre-se que o seu endereço de email aceita apenas letras e números. Clique em 'Proceed' depois que preencher todos os campos. https://image.nostr.build/670dfda7264db393e48391f217e60a2eb87d85c2729360c8ef6fe0cf52508ab4.jpg
Uma página vai aparecer pedindo para confirmar as credenciais da sua nova conta. Se tudo estiver certo apenas clique em 'Confirm and Create Mailbox'. Se tudo ocorrer como conforme haverá uma confirmação de que a sua nova conta foi criada com sucesso. Após isso aguarde por volta de 5 minutos antes de tentar acessá-la, para que haja tempo suficiente para o servidor atualizar o banco de dados. https://image.nostr.build/ec58fb826bffa60791fedfd9c89a25d592ac3d11645b270c936c60a7c59c067f.jpg https://image.nostr.build/a2b7710d1e3cbb36431acb9055fd62937986b4da4b1a1bbb06d3f3cb1f544fd3.jpg
Pronto! Sua nova conta de email na I2P foi criada. Agora vamos para a próxima etapa: como acessar a sua conta via um cliente de email.
2. Configurando os túneis cliente de SMTP e POP3
O hq.postman não possui um cliente web que nos permite acessar a nossa conta pelo navegador. Para isso precisamos usar um cliente como Thunderbird e configurar os túneis cliente no I2Pd que serão necessários para o Thunderbird se comunicar com o servidor pela I2P.
Caso não tenha instalado o Thunderbird ainda, faça-o agora antes de prosseguir.
Vamos configurar os túneis cliente do servidor de email no nosso roteador. Para isso abra um terminal ou o seu gestor de arquivos e vá para a pasta de configuração de túneis do I2P. Em Linux esse diretório se localiza em /etc/i2pd/tunnels.d. Em Windows, essa pasta se localiza em C:\users\user\APPDATA\i2pd. Na pasta tunnels.d crie dois arquivos: smtp.postman.conf e pop-postman.conf. Lembre-se que em Linux você precisa de permissões de root para escrever na pasta de configuração. Use o comando sudoedit
para isso. Edite-os conforme as imagens a seguir:
Arquivo pop-postman.conf https://image.nostr.build/7e03505c8bc3b632ca5db1f8eaefc6cecb4743cd2096d211dd90bbdc16fe2593.jpg
Arquivo smtp-postman.conf https://image.nostr.build/2d06c021841dedd6000c9fc2a641ed519b3be3c6125000b188842cd0a5af3d16.jpg
Salve os arquivos e reinicie o serviço do I2Pd. Em Linux isso é feito pelo comando:
sudo systemctl restart i2pd
Entre no Webconsole do I2Pd pelo navegador (localhost:7070) e na seção I2P Tunnels, verifique se os túneis pop-postman e smtp-postman foram criados, caso contrário verifique se há algum erro nos arquivos e reinicie o serviço.Com os túneis cliente criados, vamos agora configurar o Thunderbird
3. Configurando o Thunderbird para acessar a nossa conta
Abra o Thunderbird e clique em criar uma nova conta de email. Se você não tiver nenhum conta previamente presente nele você vai ser diretamente recebido pela janela de criação de conta a seguir. https://image.nostr.build/e9509d7bd30623716ef9adcad76c1d465f5bc3d5840e0c35fe4faa85740f41b4.jpg https://image.nostr.build/688b59b8352a17389902ec1e99d7484e310d7d287491b34f562b8cdd9dbe8a99.jpg
Coloque as suas credenciais, mas não clique ainda em Continuar. Clique antes em Configure Manually, já que precisamos configurar manualmente os servidores de SMTP e POP3 para, respectivamente, enviar e receber mensagens.
Preencha os campos como na imagem a seguir. Detalhe: Não coloque o seu endereço completo com o @mail.i2p, apenas o nome da sua conta. https://image.nostr.build/4610b0315c0a3b741965d3d7c1e4aff6425a167297e323ba8490f4325f40cdcc.jpg
Clique em Re-test para verificar a integridade da conexão. Se tudo estiver certo uma mensagem irá aparecer avisando que as configurações do servidores estão corretas. Clique em Done assim que estiver pronto para prosseguir. https://image.nostr.build/8a47bb292f94b0d9d474d4d4a134f8d73afb84ecf1d4c0a7eb6366d46bf3973a.jpg
A seguinte mensagem vai aparecer alertando que não estamos usando criptografia no envio das credenciais. Não há problema nenhum aqui, pois a I2P está garantindo toda a proteção e anonimato dos nossos dados, o que dispensa a necessidade de uso de TLS ou qualquer tecnologia similar nas camadas acima. Marque a opção 'I Understand the risks' e clique em 'Continue' https://image.nostr.build/9c1bf585248773297d2cb1d9705c1be3bd815e2be85d4342227f1db2f13a9cc6.jpg
E por fim, se tudo ocorreu como devido sua conta será criada com sucesso e você agora será capaz de enviar e receber emails pela I2P usando essa conta. https://image.nostr.build/8ba7f2c160453c9bfa172fa9a30b642a7ee9ae3eeb9b78b4dc24ce25aa2c7ecc.jpg
4. Observações e considerações finais
Como informado pelo próprio site do hq.postman, o domínio @mail.i2p serve apenas para emails enviados dentro da I2P. Emails enviados pela surface devem usar o domínio @i2pmai.org. É imprescindível que você saiba usar o PGP para assinar e criptografar as suas mensagens, dado que provavelmente as mensagens não são armazenadas de forma criptografada enquanto elas estão armazenadas no servidor. Como o protocolo POP3 delete as mensagens no imediato momento em que você as recebe, não há necessidade de fazer qualquer limpeza na sua conta de forma manual.
Por fim, espero que esse tutorial tenha sido útil para vocês. Que seu conhecimento tenha expandido ainda mais com as informações trazidas aqui. Até a próxima.
