2025-05-20 15:53:48This 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.

2025-05-20 15:47:16Here’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.

2025-05-20 13:49:50I’ve written about MSTR twice already, https://www.chrisliss.com/p/mstr and https://www.chrisliss.com/p/mstr-part-2, but I want to focus on legendary short seller James Chanos’ current trade wherein he buys bitcoin (via ETF) and shorts MSTR, in essence to “be like Mike” Saylor who sells MSTR shares at the market and uses them to add bitcoin to the company’s balance sheet. After all, if it’s good enough for Saylor, why shouldn’t everyone be doing it — shorting a company whose stock price is more than 2x its bitcoin holdings and using the proceeds to buy the bitcoin itself?
Saylor himself has said selling shares at 2x NAV (net asset value) to buy bitcoin is like selling dollars for two dollars each, and Chanos has apparently decided to get in while the getting (market cap more than 2x net asset value) is good. If the price of bitcoin moons, sending MSTR’s shares up, you are more than hedged in that event, too. At least that’s the theory.
The problem with this bet against MSTR’s mNAV, i.e., you are betting MSTR’s market cap will converge 1:1 toward its NAV in the short and medium term is this trade does not exist in a vacuum. Saylor has described how his ATM’s (at the market) sales of shares are accretive in BTC per share because of this very premium they carry. Yes, we’ll dilute your shares of the company, but because we’re getting you 2x the bitcoin per share, you are getting an ever smaller slice of an ever bigger overall pie, and the pie is growing 2x faster than your slice is reducing. (I https://www.chrisliss.com/p/mstr how this works in my first post.)
But for this accretion to continue, there must be a constant supply of “greater fools” to pony up for the infinitely printable shares which contain only half their value in underlying bitcoin. Yes, those shares will continue to accrete more BTC per share, but only if there are more fools willing to make this trade in the future. So will there be a constant supply of such “fools” to keep fueling MSTR’s mNAV multiple indefinitely?
Yes, there will be in my opinion because you have to look at the trade from the prospective fools’ perspective. Those “fools” are not trading bitcoin for MSTR, they are trading their dollars, selling other equities to raise them maybe, but in the end it’s a dollars for shares trade. They are not selling bitcoin for them.
You might object that those same dollars could buy bitcoin instead, so they are surely trading the opportunity cost of buying bitcoin for them, but if only 5-10 percent of the market (or less) is buying bitcoin itself, the bucket in which which those “fools” reside is the entire non-bitcoin-buying equity market. (And this is not considering the even larger debt market which Saylor has yet to tap in earnest.)
So for those 90-95 percent who do not and are not presently planning to own bitcoin itself, is buying MSTR a fool’s errand, so to speak? Not remotely. If MSTR shares are infinitely printable ATM, they are still less so than the dollar and other fiat currencies. And MSTR shares are backed 2:1 by bitcoin itself, while the fiat currencies are backed by absolutely nothing. So if you hold dollars or euros, trading them for MSTR shares is an errand more sage than foolish.
That’s why this trade (buying BTC and shorting MSTR) is so dangerous. Not only are there many people who won’t buy BTC buying MSTR, there are many funds and other investment entities who are only able to buy MSTR.
Do you want to get BTC at 1:1 with the 5-10 percent or MSTR backed 2:1 with the 90-95 percent. This is a bit like medical tests that have a 95 percent accuracy rate for an asymptomatic disease that only one percent of the population has. If someone tests positive, it’s more likely to be a false one than an indication he has the disease*. The accuracy rate, even at 19:1, is subservient to the size of the respective populations.
At some point this will no longer be the case, but so long as the understanding of bitcoin is not widespread, so long as the dollar is still the unit of account, the “greater fools” buying MSTR are still miles ahead of the greatest fools buying neither, and the stock price and mNAV should only increase.
. . .
One other thought: it’s more work to play defense than offense because the person on offense knows where he’s going, and the defender can only react to him once he moves. Similarly, Saylor by virtue of being the issuer of the shares knows when more will come online while Chanos and other short sellers are borrowing them to sell in reaction to Saylor’s strategy. At any given moment, Saylor can pause anytime, choosing to issue convertible debt or preferred shares with which to buy more bitcoin, and the shorts will not be given advance notice.
If the price runs, and there is no ATM that week because Saylor has stopped on a dime, so to speak, the shorts will be left having to scramble to change directions and buy the shares back to cover. Their momentum might be in the wrong direction, though, and like Allen Iverson breaking ankles with a crossover, Saylor might trigger a massive short squeeze, rocketing the share price ever higher. That’s why he actually welcomes Chanos et al trying this copycat strategy — it becomes the fuel for outsized gains.
For that reason, news that Chanos is shorting MSTR has not shaken my conviction, though there are other more pertinent https://www.chrisliss.com/p/mstr-part-2 with MSTR, of which one should be aware. And as always, do your own due diligence before investing in anything.
* To understand this, consider a population of 100,000, with one percent having a disease. That means 1,000 have it, 99,000 do not. If the test is 95 percent accurate, and everyone is tested, 950 of the 1,000 will test positive (true positives), 50 who have it will test negative (false negatives.) Of the positives, 95 percent of 99,000 (94,050) will test negative (true negatives) and five percent (4,950) will test positive (false positives). That means 4,950 out of 5,900 positives (84%) will be false.

Listen to the full episode here:
<<https://fountain.fm/episode/Ln9Ej0zCZ5dEwfo8w2Ho>>
Bitcoin has always been a narrative revolution disguised as code. White paper, cypherpunk lore, pizza‑day legends - every block is a paragraph in the world’s most relentless epic. But code alone rarely converts the skeptic; it’s the camp‑fire myth that slips past the prefrontal cortex and shakes hands with the limbic system. People don’t adopt protocols first - they fall in love with protagonists.
Early adopters heard the white‑paper hymn, but most folks need characters first: a pizza‑day dreamer; a mother in a small country, crushed by the cost of remittance; a Warsaw street vendor swapping złoty for sats. When their arcs land, the brain releases a neurochemical OP_RETURN which says, “I belong in this plot.” That’s the sly roundabout orange pill: conviction smuggled inside catharsis.
That’s why, from 22–25 May in Warsaw’s Kinoteka, the Bitcoin Film Fest is loading its reels with rebellion. Each documentary, drama, and animated rabbit‑hole is a stealth wallet, zipping conviction straight into the feels of anyone still clasped within the cold claw of fiat. You come for the plot, you leave checking block heights.
Here's the clip of the sermon from the episode:

2025-05-16 18:06:46Bitcoin has always been rooted in freedom and resistance to authority. I get that many of you are conflicted about the US Government stacking but by design we cannot stop anyone from using bitcoin. Many have asked me for my thoughts on the matter, so let’s rip it.
Concern
One of the most glaring issues with the strategic bitcoin reserve is its foundation, built on stolen bitcoin. For those of us who value private property this is an obvious betrayal of our core principles. Rather than proof of work, the bitcoin that seeds this reserve has been taken by force. The US Government should return the bitcoin stolen from Bitfinex and the Silk Road.
Using stolen bitcoin for the reserve creates a perverse incentive. If governments see bitcoin as a valuable asset, they will ramp up efforts to confiscate more bitcoin. The precedent is a major concern, and I stand strongly against it, but it should be also noted that governments were already seizing coin before the reserve so this is not really a change in policy.
Ideally all seized bitcoin should be burned, by law. This would align incentives properly and make it less likely for the government to actively increase coin seizures. Due to the truly scarce properties of bitcoin, all burned bitcoin helps existing holders through increased purchasing power regardless. This change would be unlikely but those of us in policy circles should push for it regardless. It would be best case scenario for American bitcoiners and would create a strong foundation for the next century of American leadership.
Optimism
The entire point of bitcoin is that we can spend or save it without permission. That said, it is a massive benefit to not have one of the strongest governments in human history actively trying to ruin our lives.
Since the beginning, bitcoiners have faced horrible regulatory trends. KYC, surveillance, and legal cases have made using bitcoin and building bitcoin businesses incredibly difficult. It is incredibly important to note that over the past year that trend has reversed for the first time in a decade. A strategic bitcoin reserve is a key driver of this shift. By holding bitcoin, the strongest government in the world has signaled that it is not just a fringe technology but rather truly valuable, legitimate, and worth stacking.
This alignment of incentives changes everything. The US Government stacking proves bitcoin’s worth. The resulting purchasing power appreciation helps all of us who are holding coin and as bitcoin succeeds our government receives direct benefit. A beautiful positive feedback loop.
Realism
We are trending in the right direction. A strategic bitcoin reserve is a sign that the state sees bitcoin as an asset worth embracing rather than destroying. That said, there is a lot of work left to be done. We cannot be lulled into complacency, the time to push forward is now, and we cannot take our foot off the gas. We have a seat at the table for the first time ever. Let's make it worth it.
We must protect the right to free usage of bitcoin and other digital technologies. Freedom in the digital age must be taken and defended, through both technical and political avenues. Multiple privacy focused developers are facing long jail sentences for building tools that protect our freedom. These cases are not just legal battles. They are attacks on the soul of bitcoin. We need to rally behind them, fight for their freedom, and ensure the ethos of bitcoin survives this new era of government interest. The strategic reserve is a step in the right direction, but it is up to us to hold the line and shape the future.

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

2025-05-16 17:51:54In much of the world, it is incredibly difficult to access U.S. dollars. Local currencies are often poorly managed and riddled with corruption. Billions of people demand a more reliable alternative. While the dollar has its own issues of corruption and mismanagement, it is widely regarded as superior to the fiat currencies it competes with globally. As a result, Tether has found massive success providing low cost, low friction access to dollars. Tether claims 400 million total users, is on track to add 200 million more this year, processes 8.1 million transactions daily, and facilitates $29 billion in daily transfers. Furthermore, their estimates suggest nearly 40% of users rely on it as a savings tool rather than just a transactional currency.
Tether’s rise has made the company a financial juggernaut. Last year alone, Tether raked in over $13 billion in profit, with a lean team of less than 100 employees. Their business model is elegantly simple: hold U.S. Treasuries and collect the interest. With over $113 billion in Treasuries, Tether has turned a straightforward concept into a profit machine.
Tether’s success has resulted in many competitors eager to claim a piece of the pie. This has triggered a massive venture capital grift cycle in USD tokens, with countless projects vying to dethrone Tether. Due to Tether’s entrenched network effect, these challengers face an uphill battle with little realistic chance of success. Most educated participants in the space likely recognize this reality but seem content to perpetuate the grift, hoping to cash out by dumping their equity positions on unsuspecting buyers before they realize the reality of the situation.
Historically, Tether’s greatest vulnerability has been U.S. government intervention. For over a decade, the company operated offshore with few allies in the U.S. establishment, making it a major target for regulatory action. That dynamic has shifted recently and Tether has seized the opportunity. By actively courting U.S. government support, Tether has fortified their position. This strategic move will likely cement their status as the dominant USD token for years to come.
While undeniably a great tool for the millions of users that rely on it, Tether is not without flaws. As a centralized, trusted third party, it holds the power to freeze or seize funds at its discretion. Corporate mismanagement or deliberate malpractice could also lead to massive losses at scale. In their goal of mitigating regulatory risk, Tether has deepened ties with law enforcement, mirroring some of the concerns of potential central bank digital currencies. In practice, Tether operates as a corporate CBDC alternative, collaborating with authorities to surveil and seize funds. The company proudly touts partnerships with leading surveillance firms and its own data reveals cooperation in over 1,000 law enforcement cases, with more than $2.5 billion in funds frozen.
The global demand for Tether is undeniable and the company’s profitability reflects its unrivaled success. Tether is owned and operated by bitcoiners and will likely continue to push forward strategic goals that help the movement as a whole. Recent efforts to mitigate the threat of U.S. government enforcement will likely solidify their network effect and stifle meaningful adoption of rival USD tokens or CBDCs. Yet, for all their achievements, Tether is simply a worse form of money than bitcoin. Tether requires trust in a centralized entity, while bitcoin can be saved or spent without permission. Furthermore, Tether is tied to the value of the US Dollar which is designed to lose purchasing power over time, while bitcoin, as a truly scarce asset, is designed to increase in purchasing power with adoption. As people awaken to the risks of Tether’s control, and the benefits bitcoin provides, bitcoin adoption will likely surpass it.

2025-05-16 19:23:58This article was originally part of the sermon of Plebchain Radio Episode 110 (May 2, 2025) that nostr:nprofile1qyxhwumn8ghj7mn0wvhxcmmvqyg8wumn8ghj7mn0wd68ytnvv9hxgqpqtvqc82mv8cezhax5r34n4muc2c4pgjz8kaye2smj032nngg52clq7fgefr and I did with nostr:nprofile1qythwumn8ghj7ct5d3shxtnwdaehgu3wd3skuep0qyt8wumn8ghj7ct4w35zumn0wd68yvfwvdhk6tcqyzx4h2fv3n9r6hrnjtcrjw43t0g0cmmrgvjmg525rc8hexkxc0kd2rhtk62 and nostr:nprofile1qyxhwumn8ghj7mn0wvhxcmmvqyg8wumn8ghj7mn0wd68ytnvv9hxgqpq4wxtsrj7g2jugh70pfkzjln43vgn4p7655pgky9j9w9d75u465pqahkzd0 of the nostr:nprofile1qythwumn8ghj7ct5d3shxtnwdaehgu3wd3skuep0qyt8wumn8ghj7etyv4hzumn0wd68ytnvv9hxgtcqyqwfvwrccp4j2xsuuvkwg0y6a20637t6f4cc5zzjkx030dkztt7t5hydajn
Listen to the full episode here:
<https://fountain.fm/episode/Ln9Ej0zCZ5dEwfo8w2Ho>
Bitcoin has always been a narrative revolution disguised as code. White paper, cypherpunk lore, pizza‑day legends - every block is a paragraph in the world’s most relentless epic. But code alone rarely converts the skeptic; it’s the camp‑fire myth that slips past the prefrontal cortex and shakes hands with the limbic system. People don’t adopt protocols first - they fall in love with protagonists.
Early adopters heard the white‑paper hymn, but most folks need characters first: a pizza‑day dreamer; a mother in a small country, crushed by the cost of remittance; a Warsaw street vendor swapping złoty for sats. When their arcs land, the brain releases a neurochemical OP_RETURN which says, “I belong in this plot.” That’s the sly roundabout orange pill: conviction smuggled inside catharsis.
That’s why, from 22–25 May in Warsaw’s Kinoteka, the Bitcoin Film Fest is loading its reels with rebellion. Each documentary, drama, and animated rabbit‑hole is a stealth wallet, zipping conviction straight into the feels of anyone still clasped within the cold claw of fiat. You come for the plot, you leave checking block heights.
Here's the clip of the sermon from the episode:

2025-05-16 17:12:05One of the most common criticisms leveled against nostr is the perceived lack of assurance when it comes to data storage. Critics argue that without a centralized authority guaranteeing that all data is preserved, important information will be lost. They also claim that running a relay will become prohibitively expensive. While there is truth to these concerns, they miss the mark. The genius of nostr lies in its flexibility, resilience, and the way it harnesses human incentives to ensure data availability in practice.
A nostr relay is simply a server that holds cryptographically verifiable signed data and makes it available to others. Relays are simple, flexible, open, and require no permission to run. Critics are right that operating a relay attempting to store all nostr data will be costly. What they miss is that most will not run all encompassing archive relays. Nostr does not rely on massive archive relays. Instead, anyone can run a relay and choose to store whatever subset of data they want. This keeps costs low and operations flexible, making relay operation accessible to all sorts of individuals and entities with varying use cases.
Critics are correct that there is no ironclad guarantee that every piece of data will always be available. Unlike bitcoin where data permanence is baked into the system at a steep cost, nostr does not promise that every random note or meme will be preserved forever. That said, in practice, any data perceived as valuable by someone will likely be stored and distributed by multiple entities. If something matters to someone, they will keep a signed copy.
Nostr is the Streisand Effect in protocol form. The Streisand effect is when an attempt to suppress information backfires, causing it to spread even further. With nostr, anyone can broadcast signed data, anyone can store it, and anyone can distribute it. Try to censor something important? Good luck. The moment it catches attention, it will be stored on relays across the globe, copied, and shared by those who find it worth keeping. Data deemed important will be replicated across servers by individuals acting in their own interest.
Nostr’s distributed nature ensures that the system does not rely on a single point of failure or a corporate overlord. Instead, it leans on the collective will of its users. The result is a network where costs stay manageable, participation is open to all, and valuable verifiable data is stored and distributed forever.

2025-05-15 15:31:45Capitalism is the most effective system for scaling innovation. The pursuit of profit is an incredibly powerful human incentive. Most major improvements to human society and quality of life have resulted from this base incentive. Market competition often results in the best outcomes for all.
That said, some projects can never be monetized. They are open in nature and a business model would centralize control. Open protocols like bitcoin and nostr are not owned by anyone and if they were it would destroy the key value propositions they provide. No single entity can or should control their use. Anyone can build on them without permission.
As a result, open protocols must depend on donation based grant funding from the people and organizations that rely on them. This model works but it is slow and uncertain, a grind where sustainability is never fully reached but rather constantly sought. As someone who has been incredibly active in the open source grant funding space, I do not think people truly appreciate how difficult it is to raise charitable money and deploy it efficiently.
Projects that can be monetized should be. Profitability is a super power. When a business can generate revenue, it taps into a self sustaining cycle. Profit fuels growth and development while providing projects independence and agency. This flywheel effect is why companies like Google, Amazon, and Apple have scaled to global dominance. The profit incentive aligns human effort with efficiency. Businesses must innovate, cut waste, and deliver value to survive.
Contrast this with non monetized projects. Without profit, they lean on external support, which can dry up or shift with donor priorities. A profit driven model, on the other hand, is inherently leaner and more adaptable. It is not charity but survival. When survival is tied to delivering what people want, scale follows naturally.
The real magic happens when profitable, sustainable businesses are built on top of open protocols and software. Consider the many startups building on open source software stacks, such as Start9, Mempool, and Primal, offering premium services on top of the open source software they build out and maintain. Think of companies like Block or Strike, which leverage bitcoin’s open protocol to offer their services on top. These businesses amplify the open software and protocols they build on, driving adoption and improvement at a pace donations alone could never match.
When you combine open software and protocols with profit driven business the result are lean, sustainable companies that grow faster and serve more people than either could alone. Bitcoin’s network, for instance, benefits from businesses that profit off its existence, while nostr will expand as developers monetize apps built on the protocol.
Capitalism scales best because competition results in efficiency. Donation funded protocols and software lay the groundwork, while market driven businesses build on top. The profit incentive acts as a filter, ensuring resources flow to what works, while open systems keep the playing field accessible, empowering users and builders. Together, they create a flywheel of innovation, growth, and global benefit.

2025-05-15 01:22:34เมื่อพูดถึง Bitcoin Standard หลายคนมักนึกถึงภาพโลกอนาคตที่ทุกคนใช้บิตคอยน์ซื้อกาแฟหรือของใช้ในชีวิตประจำวัน ภาพแบบนั้นดูเหมือนไกลตัวและเป็นไปไม่ได้ในความเป็นจริง หลายคนถึงกับพูดว่า “คงไม่ทันเห็นในช่วงชีวิตนี้หรอก” แต่ในมุมมองของผม Bitcoin Standard อาจไม่ได้เริ่มต้นจากการที่เราจ่ายบิตคอยน์โดยตรงในร้านค้า แต่อาจเริ่มจากบางสิ่งที่เงียบกว่า ลึกกว่า และเกิดขึ้นแล้วในขณะนี้ นั่นคือ การล่มสลายทีละน้อยของระบบเฟียตที่เราใช้กันอยู่
ระบบเงินที่อิงกับอำนาจรัฐกำลังเข้าสู่ช่วงขาลง รัฐบาลทั่วโลกกำลังจมอยู่ในภาระหนี้ระดับประวัติการณ์ แม้แต่ประเทศมหาอำนาจก็เริ่มแสดงสัญญาณของภาวะเสี่ยงผิดนัดชำระหนี้ อัตราเงินเฟ้อกลายเป็นปัญหาเรื้อรังที่ไม่มีท่าทีจะหายไป ธนาคารที่เคยโอนฟรีเริ่มกลับมาคิดค่าธรรมเนียม และประชาชนก็เริ่มรู้สึกถึงการเสื่อมศรัทธาในระบบการเงินดั้งเดิม แม้จะยังพูดกันไม่เต็มเสียงก็ตาม
ในขณะเดียวกัน บิตคอยน์เองก็กำลังพัฒนาแบบเงียบ ๆ เงียบ... แต่ไม่เคยหยุด โดยเฉพาะในระดับ Layer 2 ที่เริ่มแสดงศักยภาพอย่างจริงจัง Lightning Network เป็น Layer 2 ที่เปิดใช้งานมาได้ระยะเวลสหนึ่ง และยังคงมีบทบาทสำคัญที่สุดในระบบนิเวศของบิตคอยน์ มันทำให้การชำระเงินเร็วขึ้น มีต้นทุนต่ำ และไม่ต้องบันทึกทุกธุรกรรมลงบล็อกเชน เครือข่ายนี้กำลังขยายตัวทั้งในแง่ของโหนดและการใช้งานจริงทั่วโลก
ขณะเดียวกัน Layer 2 ทางเลือกอื่นอย่าง Ark Protocol ก็กำลังพัฒนาเพื่อตอบโจทย์ด้านความเป็นส่วนตัวและประสบการณ์ใช้งานที่ง่าย BitVM เปิดแนวทางใหม่ให้บิตคอยน์รองรับ smart contract ได้ในระดับ Turing-complete ซึ่งทำให้เกิดความเป็นไปได้ในกรณีใช้งานอีกมากมาย และเทคโนโลยีที่น่าสนใจอย่าง Taproot Assets, Cashu และ Fedimint ก็ทำให้การออกโทเคนหรือสกุลเงินที่อิงกับบิตคอยน์เป็นจริงได้บนโครงสร้างของบิตคอยน์เอง
เทคโนโลยีเหล่านี้ไม่ใช่การเติบโตแบบปาฏิหาริย์ แต่มันคืบหน้าอย่างต่อเนื่องและมั่นคง และนั่นคือเหตุผลที่มันจะ “อยู่รอด” ได้ในระยะยาว เมื่อฐานของความน่าเชื่อถือไม่ใช่บริษัท รัฐบาล หรือทุน แต่คือสิ่งที่ตรวจสอบได้และเปลี่ยนกฎไม่ได้
แน่นอนว่าบิตคอยน์ต้องแข่งขันกับ stable coin, เงินดิจิทัลของรัฐ และ cryptocurrency อื่น ๆ แต่สิ่งที่ทำให้มันเหนือกว่านั้นไม่ใช่ฟีเจอร์ หากแต่เป็นความทนทาน และความมั่นคงของกฎที่ไม่มีใครเปลี่ยนได้ ไม่มีทีมพัฒนา ไม่มีบริษัท ไม่มีประตูปิด หรือการยึดบัญชี มันยืนอยู่บนคณิตศาสตร์ พลังงาน และเวลา
หลายกรณีใช้งานที่เคยถูกทดลองในโลกคริปโตจะค่อย ๆ เคลื่อนเข้ามาสู่บิตคอยน์ เพราะโครงสร้างของมันแข็งแกร่งกว่า ไม่ต้องการทีมพัฒนาแกนกลาง ไม่ต้องพึ่งกลไกเสี่ยงต่อการผูกขาด และไม่ต้องการ “ความเชื่อใจ” จากใครเลย
Bitcoin Standard ที่ผมพูดถึงจึงไม่ใช่การเปลี่ยนแปลงแบบพลิกหน้ามือเป็นหลังมือ แต่คือการ “เปลี่ยนฐานของระบบ” ทีละชั้น ระบบการเงินใหม่ที่อิงอยู่กับบิตคอยน์กำลังเกิดขึ้นแล้ว มันไม่ใช่โลกที่ทุกคนถือเหรียญบิตคอยน์ แต่มันคือโลกที่คนใช้อาจไม่รู้ตัวด้วยซ้ำว่า “สิ่งที่เขาใช้นั้นอิงอยู่กับบิตคอยน์”
ผู้คนอาจใช้เงินดิจิทัลที่สร้างบน Layer 3 หรือ Layer 4 ผ่านแอป ผ่านแพลตฟอร์ม หรือผ่านสกุลเงินใหม่ที่ดูไม่ต่างจากเดิม แต่เบื้องหลังของระบบจะผูกไว้กับบิตคอยน์
และถ้ามองในเชิงพัฒนาการ บิตคอยน์ก็เหมือนกับอินเทอร์เน็ต ครั้งหนึ่งอินเทอร์เน็ตก็ถูกมองว่าเข้าใจยาก ต้องพิมพ์ http ต้องรู้จัก TCP/IP ต้องตั้ง proxy เอง แต่ปัจจุบันผู้คนใช้งานอินเทอร์เน็ตโดยไม่รู้ว่าเบื้องหลังมีอะไรเลย บิตคอยน์กำลังเดินตามเส้นทางเดียวกัน โปรโตคอลกำลังถอยออกจากสายตา และวันหนึ่งเราจะ “ใช้มัน” โดยไม่ต้องรู้ว่ามันคืออะไร
หากนับจากช่วงเริ่มต้นของอินเทอร์เน็ตในยุค 1990 จนกลายเป็นโครงสร้างหลักของโลกในสองทศวรรษ เส้นเวลาของบิตคอยน์ก็กำลังเดินตามรอยเท้าของอินเทอร์เน็ต และถ้าเราเชื่อว่าวัฏจักรของเทคโนโลยีมีจังหวะของมันเอง เราก็จะรู้ว่า Bitcoin Standard นั้นไม่ใช่เรื่องของอนาคตไกลโพ้น แต่มันเกิดขึ้นแล้ว

2025-05-20 15:50:48For years American bitcoin miners have argued for more efficient and free energy markets. It benefits everyone if our energy infrastructure is as efficient and robust as possible. Unfortunately, broken incentives have led to increased regulation throughout the sector, incentivizing less efficient energy sources such as solar and wind at the detriment of more efficient alternatives.
The result has been less reliable energy infrastructure for all Americans and increased energy costs across the board. This naturally has a direct impact on bitcoin miners: increased energy costs make them less competitive globally.
Bitcoin mining represents a global energy market that does not require permission to participate. Anyone can plug a mining computer into power and internet to get paid the current dynamic market price for their work in bitcoin. Using cellphone or satellite internet, these mines can be located anywhere in the world, sourcing the cheapest power available.
Absent of regulation, bitcoin mining naturally incentivizes the build out of highly efficient and robust energy infrastructure. Unfortunately that world does not exist and burdensome regulations remain the biggest threat for US based mining businesses. Jurisdictional arbitrage gives miners the option of moving to a friendlier country but that naturally comes with its own costs.
Enter AI. With the rapid development and release of AI tools comes the requirement of running massive datacenters for their models. Major tech companies are scrambling to secure machines, rack space, and cheap energy to run full suites of AI enabled tools and services. The most valuable and powerful tech companies in America have stumbled into an accidental alliance with bitcoin miners: THE NEED FOR CHEAP AND RELIABLE ENERGY.
Our government is corrupt. Money talks. These companies will push for energy freedom and it will greatly benefit us all.

2025-05-20 15:50:22There is something quietly rebellious about stacking sats. In a world obsessed with instant gratification, choosing to patiently accumulate Bitcoin, one sat at a time, feels like a middle finger to the hype machine. But to do it right, you have got to stay humble. Stack too hard with your head in the clouds, and you will trip over your own ego before the next halving even hits.
Small Wins
Stacking sats is not glamorous. Discipline. Stacking every day, week, or month, no matter the price, and letting time do the heavy lifting. Humility lives in that consistency. You are not trying to outsmart the market or prove you are the next "crypto" prophet. Just a regular person, betting on a system you believe in, one humble stack at a time. Folks get rekt chasing the highs. They ape into some shitcoin pump, shout about it online, then go silent when they inevitably get rekt. The ones who last? They stack. Just keep showing up. Consistency. Humility in action. Know the game is long, and you are not bigger than it.
Ego is Volatile
Bitcoin’s swings can mess with your head. One day you are up 20%, feeling like a genius and the next down 30%, questioning everything. Ego will have you panic selling at the bottom or over leveraging the top. Staying humble means patience, a true bitcoin zen. Do not try to "beat” Bitcoin. Ride it. Stack what you can afford, live your life, and let compounding work its magic.
Simplicity
There is a beauty in how stacking sats forces you to rethink value. A sat is worth less than a penny today, but every time you grab a few thousand, you plant a seed. It is not about flaunting wealth but rather building it, quietly, without fanfare. That mindset spills over. Cut out the noise: the overpriced coffee, fancy watches, the status games that drain your wallet. Humility is good for your soul and your stack. I have a buddy who has been stacking since 2015. Never talks about it unless you ask. Lives in a decent place, drives an old truck, and just keeps stacking. He is not chasing clout, he is chasing freedom. That is the vibe: less ego, more sats, all grounded in life.
The Big Picture
Stack those sats. Do it quietly, do it consistently, and do not let the green days puff you up or the red days break you down. Humility is the secret sauce, it keeps you grounded while the world spins wild. In a decade, when you look back and smile, it will not be because you shouted the loudest. It will be because you stayed the course, one sat at a time. \ \ Stay Humble and Stack Sats. 🫡

2025-05-18 04:14:48Abstract
This document proposes a novel architecture that decouples the peer-to-peer (P2P) communication layer from the Bitcoin protocol and replaces or augments it with the Nostr protocol. The goal is to improve censorship resistance, performance, modularity, and maintainability by migrating transaction propagation and block distribution to the Nostr relay network.
Introduction
Bitcoin’s current architecture relies heavily on its P2P network to propagate transactions and blocks. While robust, it has limitations in terms of flexibility, scalability, and censorship resistance in certain environments. Nostr, a decentralized event-publishing protocol, offers a multi-star topology and a censorship-resistant infrastructure for message relay.
This proposal outlines how Bitcoin communication could be ported to Nostr while maintaining consensus and verification through standard Bitcoin clients.
Motivation
- Enhanced Censorship Resistance: Nostr’s architecture enables better relay redundancy and obfuscation of transaction origin.
- Simplified Lightweight Nodes: Removing the full P2P stack allows for lightweight nodes that only verify blockchain data and communicate over Nostr.
- Architectural Modularity: Clean separation between validation and communication enables easier auditing, upgrades, and parallel innovation.
- Faster Propagation: Nostr’s multi-star network may provide faster propagation of transactions and blocks compared to the mesh-like Bitcoin P2P network.
Architecture Overview
Components
-
Bitcoin Minimal Node (BMN):
- Verifies blockchain and block validity.
- Maintains UTXO set and handles mempool logic.
- Connects to Nostr relays instead of P2P Bitcoin peers.
-
Bridge Node:
- Bridges Bitcoin P2P traffic to and from Nostr relays.
- Posts new transactions and blocks to Nostr.
- Downloads mempool content and block headers from Nostr.
-
Nostr Relays:
- Accept Bitcoin-specific event kinds (transactions and blocks).
- Store mempool entries and block messages.
- Optionally broadcast fee estimation summaries and tipsets.
Event Format
Proposed reserved Nostr
kind
numbers for Bitcoin content (NIP/BIP TBD):| Nostr Kind | Purpose | |------------|------------------------| | 210000 | Bitcoin Transaction | | 210001 | Bitcoin Block Header | | 210002 | Bitcoin Block | | 210003 | Mempool Fee Estimates | | 210004 | Filter/UTXO summary |
Transaction Lifecycle
- Wallet creates a Bitcoin transaction.
- Wallet sends it to a set of configured Nostr relays.
- Relays accept and cache the transaction (based on fee policies).
- Mining nodes or bridge nodes fetch mempool contents from Nostr.
- Once mined, a block is submitted over Nostr.
- Nodes confirm inclusion and update their UTXO set.
Security Considerations
- Sybil Resistance: Consensus remains based on proof-of-work. The communication path (Nostr) is not involved in consensus.
- Relay Discoverability: Optionally bootstrap via DNS, Bitcoin P2P, or signed relay lists.
- Spam Protection: Relay-side policy, rate limiting, proof-of-work challenges, or Lightning payments.
- Block Authenticity: Nodes must verify all received blocks and reject invalid chains.
Compatibility and Migration
- Fully compatible with current Bitcoin consensus rules.
- Bridge nodes preserve interoperability with legacy full nodes.
- Nodes can run in hybrid mode, fetching from both P2P and Nostr.
Future Work
- Integration with watch-only wallets and SPV clients using verified headers via Nostr.
- Use of Nostr’s social graph for partial trust assumptions and relay reputation.
- Dynamic relay discovery using Nostr itself (relay list events).
Conclusion
This proposal lays out a new architecture for Bitcoin communication using Nostr to replace or augment the P2P network. This improves decentralization, censorship resistance, modularity, and speed, while preserving consensus integrity. It encourages innovation by enabling smaller, purpose-built Bitcoin nodes and offloading networking complexity.
This document may become both a Bitcoin Improvement Proposal (BIP-XXX) and a Nostr Improvement Proposal (NIP-XXX). Event kind range reserved: 210000–219999.

2025-05-09 13:56:57Someone asked for my thoughts, so I’ll share them thoughtfully. I’m not here to dictate how to promote Nostr—I’m still learning about it myself. While I’m not new to Nostr, freedom tech is a newer space for me. I’m skilled at advocating for topics I deeply understand, but freedom tech isn’t my expertise, so take my words with a grain of salt. Nothing I say is set in stone.
Those who need Nostr the most are the ones most vulnerable to censorship on other platforms right now. Reaching them requires real-time awareness of global issues and the dynamic relationships between governments and tech providers, which can shift suddenly. Effective Nostr promoters must grasp this and adapt quickly.
The best messengers are people from or closely tied to these at-risk regions—those who truly understand the local political and cultural dynamics. They can connect with those in need when tensions rise. Ideal promoters are rational, trustworthy, passionate about Nostr, but above all, dedicated to amplifying people’s voices when it matters most.
Forget influencers, corporate-backed figures, or traditional online PR—it comes off as inauthentic, corny, desperate and forced. Nostr’s promotion should be grassroots and organic, driven by a few passionate individuals who believe in Nostr and the communities they serve.
The idea that “people won’t join Nostr due to lack of reach” is nonsense. Everyone knows X’s “reach” is mostly with bots. If humans want real conversations, Nostr is the place. X is great for propaganda, but Nostr is for the authentic voices of the people.
Those spreading Nostr must be so passionate they’re willing to onboard others, which is time-consuming but rewarding for the right person. They’ll need to make Nostr and onboarding a core part of who they are. I see no issue with that level of dedication. I’ve been known to get that way myself at times. It’s fun for some folks.
With love, I suggest not adding Bitcoin promotion with Nostr outreach. Zaps already integrate that element naturally. (Still promote within the Bitcoin ecosystem, but this is about reaching vulnerable voices who needed Nostr yesterday.)
To promote Nostr, forget conventional strategies. “Influencers” aren’t the answer. “Influencers” are not the future. A trusted local community member has real influence—reach them. Connect with people seeking Nostr’s benefits but lacking the technical language to express it. This means some in the Nostr community might need to step outside of the Bitcoin bubble, which is uncomfortable but necessary. Thank you in advance to those who are willing to do that.
I don’t know who is paid to promote Nostr, if anyone. This piece isn’t shade. But it’s exhausting to see innocent voices globally silenced on corporate platforms like X while Nostr exists. Last night, I wondered: how many more voices must be censored before the Nostr community gets uncomfortable and thinks creatively to reach the vulnerable?
A warning: the global need for censorship-resistant social media is undeniable. If Nostr doesn’t make itself known, something else will fill that void. Let’s start this conversation.

2025-05-01 01:51:10Please respect Virginia Giuffre’s memory by refraining from asking about the circumstances or theories surrounding her passing.
Since Virginia Giuffre’s death, I’ve reflected on what she would want me to say or do. This piece is my attempt to honor her legacy.
When I first spoke with Virginia, I was struck by her unshakable hope. I had grown cynical after years in the anti-human trafficking movement, worn down by a broken system and a government that often seemed complicit. But Virginia’s passion, creativity, and belief that survivors could be heard reignited something in me. She reminded me of my younger, more hopeful self. Instead of warning her about the challenges ahead, I let her dream big, unburdened by my own disillusionment. That conversation changed me for the better, and following her lead led to meaningful progress.
Virginia was one of the bravest people I’ve ever known. As a survivor of Epstein, Maxwell, and their co-conspirators, she risked everything to speak out, taking on some of the world’s most powerful figures.
She loved when I said, “Epstein isn’t the only Epstein.” This wasn’t just about one man—it was a call to hold all abusers accountable and to ensure survivors find hope and healing.
The Epstein case often gets reduced to sensational details about the elite, but that misses the bigger picture. Yes, we should be holding all of the co-conspirators accountable, we must listen to the survivors’ stories. Their experiences reveal how predators exploit vulnerabilities, offering lessons to prevent future victims.
You’re not powerless in this fight. Educate yourself about trafficking and abuse—online and offline—and take steps to protect those around you. Supporting survivors starts with small, meaningful actions. Free online resources can guide you in being a safe, supportive presence.
When high-profile accusations arise, resist snap judgments. Instead of dismissing survivors as “crazy,” pause to consider the trauma they may be navigating. Speaking out or coping with abuse is never easy. You don’t have to believe every claim, but you can refrain from attacking accusers online.
Society also fails at providing aftercare for survivors. The government, often part of the problem, won’t solve this. It’s up to us. Prevention is critical, but when abuse occurs, step up for your loved ones and community. Protect the vulnerable. it’s a challenging but a rewarding journey.
If you’re contributing to Nostr, you’re helping build a censorship resistant platform where survivors can share their stories freely, no matter how powerful their abusers are. Their voices can endure here, offering strength and hope to others. This gives me great hope for the future.
Virginia Giuffre’s courage was a gift to the world. It was an honor to know and serve her. She will be deeply missed. My hope is that her story inspires others to take on the powerful.

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

2025-04-26 10:16:21O Contexto Legal Brasileiro e o Consentimento
No ordenamento jurídico brasileiro, o consentimento do ofendido pode, em certas circunstâncias, afastar a ilicitude de um ato que, sem ele, configuraria crime (como lesão corporal leve, prevista no Art. 129 do Código Penal). Contudo, o consentimento tem limites claros: não é válido para bens jurídicos indisponíveis, como a vida, e sua eficácia é questionável em casos de lesões corporais graves ou gravíssimas.
A prática de BDSM consensual situa-se em uma zona complexa. Em tese, se ambos os parceiros são adultos, capazes, e consentiram livre e informadamente nos atos praticados, sem que resultem em lesões graves permanentes ou risco de morte não consentido, não haveria crime. O desafio reside na comprovação desse consentimento, especialmente se uma das partes, posteriormente, o negar ou alegar coação.
A Lei Maria da Penha (Lei nº 11.340/2006)
A Lei Maria da Penha é um marco fundamental na proteção da mulher contra a violência doméstica e familiar. Ela estabelece mecanismos para coibir e prevenir tal violência, definindo suas formas (física, psicológica, sexual, patrimonial e moral) e prevendo medidas protetivas de urgência.
Embora essencial, a aplicação da lei em contextos de BDSM pode ser delicada. Uma alegação de violência por parte da mulher, mesmo que as lesões ou situações decorram de práticas consensuais, tende a receber atenção prioritária das autoridades, dada a presunção de vulnerabilidade estabelecida pela lei. Isso pode criar um cenário onde o parceiro masculino enfrenta dificuldades significativas em demonstrar a natureza consensual dos atos, especialmente se não houver provas robustas pré-constituídas.
Outros riscos:
Lesão corporal grave ou gravíssima (art. 129, §§ 1º e 2º, CP), não pode ser justificada pelo consentimento, podendo ensejar persecução penal.
Crimes contra a dignidade sexual (arts. 213 e seguintes do CP) são de ação pública incondicionada e independem de representação da vítima para a investigação e denúncia.
Riscos de Falsas Acusações e Alegação de Coação Futura
Os riscos para os praticantes de BDSM, especialmente para o parceiro que assume o papel dominante ou que inflige dor/restrição (frequentemente, mas não exclusivamente, o homem), podem surgir de diversas frentes:
- Acusações Externas: Vizinhos, familiares ou amigos que desconhecem a natureza consensual do relacionamento podem interpretar sons, marcas ou comportamentos como sinais de abuso e denunciar às autoridades.
- Alegações Futuras da Parceira: Em caso de término conturbado, vingança, arrependimento ou mudança de perspectiva, a parceira pode reinterpretar as práticas passadas como abuso e buscar reparação ou retaliação através de uma denúncia. A alegação pode ser de que o consentimento nunca existiu ou foi viciado.
- Alegação de Coação: Uma das formas mais complexas de refutar é a alegação de que o consentimento foi obtido mediante coação (física, moral, psicológica ou econômica). A parceira pode alegar, por exemplo, que se sentia pressionada, intimidada ou dependente, e que seu "sim" não era genuíno. Provar a ausência de coação a posteriori é extremamente difícil.
- Ingenuidade e Vulnerabilidade Masculina: Muitos homens, confiando na dinâmica consensual e na parceira, podem negligenciar a necessidade de precauções. A crença de que "isso nunca aconteceria comigo" ou a falta de conhecimento sobre as implicações legais e o peso processual de uma acusação no âmbito da Lei Maria da Penha podem deixá-los vulneráveis. A presença de marcas físicas, mesmo que consentidas, pode ser usada como evidência de agressão, invertendo o ônus da prova na prática, ainda que não na teoria jurídica.
Estratégias de Prevenção e Mitigação
Não existe um método infalível para evitar completamente o risco de uma falsa acusação, mas diversas medidas podem ser adotadas para construir um histórico de consentimento e reduzir vulnerabilidades:
- Comunicação Explícita e Contínua: A base de qualquer prática BDSM segura é a comunicação constante. Negociar limites, desejos, palavras de segurança ("safewords") e expectativas antes, durante e depois das cenas é crucial. Manter registros dessas negociações (e-mails, mensagens, diários compartilhados) pode ser útil.
-
Documentação do Consentimento:
-
Contratos de Relacionamento/Cena: Embora a validade jurídica de "contratos BDSM" seja discutível no Brasil (não podem afastar normas de ordem pública), eles servem como forte evidência da intenção das partes, da negociação detalhada de limites e do consentimento informado. Devem ser claros, datados, assinados e, idealmente, reconhecidos em cartório (para prova de data e autenticidade das assinaturas).
-
Registros Audiovisuais: Gravar (com consentimento explícito para a gravação) discussões sobre consentimento e limites antes das cenas pode ser uma prova poderosa. Gravar as próprias cenas é mais complexo devido a questões de privacidade e potencial uso indevido, mas pode ser considerado em casos específicos, sempre com consentimento mútuo documentado para a gravação.
Importante: a gravação deve ser com ciência da outra parte, para não configurar violação da intimidade (art. 5º, X, da Constituição Federal e art. 20 do Código Civil).
-
-
Testemunhas: Em alguns contextos de comunidade BDSM, a presença de terceiros de confiança durante negociações ou mesmo cenas pode servir como testemunho, embora isso possa alterar a dinâmica íntima do casal.
- Estabelecimento Claro de Limites e Palavras de Segurança: Definir e respeitar rigorosamente os limites (o que é permitido, o que é proibido) e as palavras de segurança é fundamental. O desrespeito a uma palavra de segurança encerra o consentimento para aquele ato.
- Avaliação Contínua do Consentimento: O consentimento não é um cheque em branco; ele deve ser entusiástico, contínuo e revogável a qualquer momento. Verificar o bem-estar do parceiro durante a cena ("check-ins") é essencial.
- Discrição e Cuidado com Evidências Físicas: Ser discreto sobre a natureza do relacionamento pode evitar mal-entendidos externos. Após cenas que deixem marcas, é prudente que ambos os parceiros estejam cientes e de acordo, talvez documentando por fotos (com data) e uma nota sobre a consensualidade da prática que as gerou.
- Aconselhamento Jurídico Preventivo: Consultar um advogado especializado em direito de família e criminal, com sensibilidade para dinâmicas de relacionamento alternativas, pode fornecer orientação personalizada sobre as melhores formas de documentar o consentimento e entender os riscos legais específicos.
Observações Importantes
- Nenhuma documentação substitui a necessidade de consentimento real, livre, informado e contínuo.
- A lei brasileira protege a "integridade física" e a "dignidade humana". Práticas que resultem em lesões graves ou que violem a dignidade de forma não consentida (ou com consentimento viciado) serão ilegais, independentemente de qualquer acordo prévio.
- Em caso de acusação, a existência de documentação robusta de consentimento não garante a absolvição, mas fortalece significativamente a defesa, ajudando a demonstrar a natureza consensual da relação e das práticas.
-
A alegação de coação futura é particularmente difícil de prevenir apenas com documentos. Um histórico consistente de comunicação aberta (whatsapp/telegram/e-mails), respeito mútuo e ausência de dependência ou controle excessivo na relação pode ajudar a contextualizar a dinâmica como não coercitiva.
-
Cuidado com Marcas Visíveis e Lesões Graves Práticas que resultam em hematomas severos ou lesões podem ser interpretadas como agressão, mesmo que consentidas. Evitar excessos protege não apenas a integridade física, mas também evita questionamentos legais futuros.
O que vem a ser consentimento viciado
No Direito, consentimento viciado é quando a pessoa concorda com algo, mas a vontade dela não é livre ou plena — ou seja, o consentimento existe formalmente, mas é defeituoso por alguma razão.
O Código Civil brasileiro (art. 138 a 165) define várias formas de vício de consentimento. As principais são:
Erro: A pessoa se engana sobre o que está consentindo. (Ex.: A pessoa acredita que vai participar de um jogo leve, mas na verdade é exposta a práticas pesadas.)
Dolo: A pessoa é enganada propositalmente para aceitar algo. (Ex.: Alguém mente sobre o que vai acontecer durante a prática.)
Coação: A pessoa é forçada ou ameaçada a consentir. (Ex.: "Se você não aceitar, eu termino com você" — pressão emocional forte pode ser vista como coação.)
Estado de perigo ou lesão: A pessoa aceita algo em situação de necessidade extrema ou abuso de sua vulnerabilidade. (Ex.: Alguém em situação emocional muito fragilizada é induzida a aceitar práticas que normalmente recusaria.)
No contexto de BDSM, isso é ainda mais delicado: Mesmo que a pessoa tenha "assinado" um contrato ou dito "sim", se depois ela alegar que seu consentimento foi dado sob medo, engano ou pressão psicológica, o consentimento pode ser considerado viciado — e, portanto, juridicamente inválido.
Isso tem duas implicações sérias:
-
O crime não se descaracteriza: Se houver vício, o consentimento é ignorado e a prática pode ser tratada como crime normal (lesão corporal, estupro, tortura, etc.).
-
A prova do consentimento precisa ser sólida: Mostrando que a pessoa estava informada, lúcida, livre e sem qualquer tipo de coação.
Consentimento viciado é quando a pessoa concorda formalmente, mas de maneira enganada, forçada ou pressionada, tornando o consentimento inútil para efeitos jurídicos.
Conclusão
Casais que praticam BDSM consensual no Brasil navegam em um terreno que exige não apenas confiança mútua e comunicação excepcional, mas também uma consciência aguçada das complexidades legais e dos riscos de interpretações equivocadas ou acusações mal-intencionadas. Embora o BDSM seja uma expressão legítima da sexualidade humana, sua prática no Brasil exige responsabilidade redobrada. Ter provas claras de consentimento, manter a comunicação aberta e agir com prudência são formas eficazes de se proteger de falsas alegações e preservar a liberdade e a segurança de todos os envolvidos. Embora leis controversas como a Maria da Penha sejam "vitais" para a proteção contra a violência real, os praticantes de BDSM, e em particular os homens nesse contexto, devem adotar uma postura proativa e prudente para mitigar os riscos inerentes à potencial má interpretação ou instrumentalização dessas práticas e leis, garantindo que a expressão de sua consensualidade esteja resguardada na medida do possível.
Importante: No Brasil, mesmo com tudo isso, o Ministério Público pode denunciar por crime como lesão corporal grave, estupro ou tortura, independente de consentimento. Então a prudência nas práticas é fundamental.

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."

2025-05-17 12:59:01The Myth and the Magic
Picture this: a group of investors, huddled around a glowing computer screen, nervously watching Bitcoin’s price. Suddenly, someone produces a stick-no ordinary stick, but a magical one. With a mischievous grin, they poke the Bitcoin. The price leaps upward. Cheers erupt. The legend of the Bitcoin stick is born.
But why does poking Bitcoin with a stick make the price go up? Why does it only work for a lucky few? And what does the data say about this mysterious phenomenon? Let’s dig in, laugh a little, and maybe learn the secret to market-moving magic.
The Statistical Side of Stick-Poking
Bitcoin’s Price: The Wild Ride
Bitcoin’s price is famous for its unpredictability. In the past year, it’s soared, dipped, and soared again, sometimes gaining more than 50% in just a few months. On a good day, billions of dollars flow through Bitcoin trades, and the price can jump thousands in a matter of hours. Clearly, something is making this happen-and it’s not just spreadsheets and financial news.
What Actually Moves the Price?
-
Scarcity: Only 21 million Bitcoins will ever exist. When more people want in, the price jumps.
-
Big News: Announcements, rumors, and meme-worthy moments can send the price flying.
-
FOMO: When people see Bitcoin rising, they rush to buy, pushing it even higher.
-
Liquidations: When traders betting against Bitcoin get squeezed, it triggers a chain reaction of buying.
But let’s be honest: none of this is as fun as poking Bitcoin with a stick.
The Magical Stick: Not Your Average Twig
Why Not Every Stick Works
You can’t just grab any old branch and expect Bitcoin to dance. The magical stick is a rare artifact, forged in the fires of internet memes and blessed by the spirit of Satoshi. Only a chosen few possess it-and when they poke, the market listens.
Signs You Have the Magical Stick
-
When you poke, Bitcoin’s price immediately jumps a few percent.
-
Your stick glows with meme energy and possibly sparkles with digital dust.
-
You have a knack for timing your poke right after a big event, like a halving or a celebrity tweet.
-
Your stick is rumored to have been whittled from the original blockchain itself.
Why Most Sticks Fail
-
No Meme Power: If your stick isn’t funny, Bitcoin ignores you.
-
Bad Timing: Poking during a bear market just annoys the blockchain.
-
Not Enough Hype: If the bitcoin community isn’t watching, your poke is just a poke.
-
Lack of Magic: Some sticks are just sticks. Sad, but true.
The Data: When the Stick Strikes
Let’s look at some numbers:
-
In the last month, Bitcoin’s price jumped over 20% right after a flurry of memes and stick-poking jokes.
-
Over the past year, every major price surge was accompanied by a wave of internet hype, stick memes, or wild speculation.
-
In the past five years, Bitcoin’s biggest leaps always seemed to follow some kind of magical event-whether a halving, a viral tweet, or a mysterious poke.
Coincidence? Maybe. But the pattern is clear: the stick works-at least when it’s magical.
The Role of Memes, Magic, and Mayhem
Bitcoin’s price is like a cat: unpredictable, easily startled, and sometimes it just wants to be left alone. But when the right meme pops up, or the right stick pokes at just the right time, the price can leap in ways that defy logic.
The bitcoin community knows this. That’s why, when Bitcoin’s stuck in a rut, you’ll see a flood of stick memes, GIFs, and magical thinking. Sometimes, it actually works.
The Secret’s in the Stick (and the Laughs)
So, does poking Bitcoin with a stick really make the price go up? If your stick is magical-blessed by memes, timed perfectly, and watched by millions-absolutely. The statistics show that hype, humor, and a little bit of luck can move markets as much as any financial report.
Next time you see Bitcoin stalling, don’t just sit there. Grab your stick, channel your inner meme wizard, and give it a poke. Who knows? You might just be the next legend in the world of bitcoin magic.
And if your stick doesn’t work, don’t worry. Sometimes, the real magic is in the laughter along the way.

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.

2025-02-15 07:02:08E-cash are coupons or tokens for Bitcoin, or Bitcoin debt notes that the mint issues. The e-cash states, essentially, "IoU 2900 sats".
They're redeemable for Bitcoin on Lightning (hard money), and therefore can be used as cash (softer money), so long as the mint has a good reputation. That means that they're less fungible than Lightning because the e-cash from one mint can be more or less valuable than the e-cash from another. If a mint is buggy, offline, or disappears, then the e-cash is unreedemable.
It also means that e-cash is more anonymous than Lightning, and that the sender and receiver's wallets don't need to be online, to transact. Nutzaps now add the possibility of parking transactions one level farther out, on a relay. The same relays that cannot keep npub profiles and follow lists consistent will now do monetary transactions.
What we then have is * a transaction on a relay that triggers * a transaction on a mint that triggers * a transaction on Lightning that triggers * a transaction on Bitcoin.
Which means that every relay that stores the nuts is part of a wildcat banking system. Which is fine, but relay operators should consider whether they wish to carry the associated risks and liabilities. They should also be aware that they should implement the appropriate features in their relay, such as expiration tags (nuts rot after 2 weeks), and to make sure that only expired nuts are deleted.
There will be plenty of specialized relays for this, so don't feel pressured to join in, and research the topic carefully, for yourself.

2025-05-20 14:55:07Chain Duel, a fast paced PvP game that takes inspiration from the classic snake game and supercharges it with Bitcoin’s Lightning Network. Imagine battling another player for dominance in a race to collect blocks, where the length of your chain isn’t just a visual cue. It represents real, staked satoshis. The player with the most Proof of Work wins, but it’s not just about gameplay; it’s about the seamless integration of the Lightning Network and real-time payments.
But how does Chain Duel manage these instant transactions with such efficiency? That’s where LNbits comes in. LNbits, an open-source wallet and payment infrastructure, handles all in-game payments making it easy for developers to focus on gameplay while LNbits takes care of everything from microtransactions to automated splits for developers and designers. In this article, we’ll dive deep into how Chain Duel leverages LNbits to streamline in-game payments and how other developers can take advantage of this powerful toolset to build the future of Lightning-powered gaming.
Let’s explore how LNbits transforms payment processing and why it’s quickly becoming a must-have for game developers working in the Bitcoin space.
Overview of Chain Duel
Chain Duel is a unique Lightning Network-inspired game that reimagines the classic snake game with a competitive twist, integrating real-time payments. Two players face off in real-time, racing to "catch" blocks and extend their chains. Each block added to the chain represents Proof of Work, and the player with the most Proof of Work wins the duel. The stakes are high, as the game represents satoshis (small units of Bitcoin) as points, with the winner taking home the prize.
The game is designed to be Lightning-native, meaning all payments within Chain Duel are processed through the Lightning Network. This ensures fast payments, reducing latency and making gameplay smooth. With additional features like practice mode, tournaments and highscores, Chain Duel creates an engaging and competitive environment for Bitcoin enthusiasts and gamers alike.
One of the standout aspects of Chain Duel is its deeper integration with the Lightning Network even at a design level. For example, actual Bitcoin blocks can appear on screen during matches, offering bonus points when mined in sync with the game. The game’s current version, still in beta, has already drawn attention within the Bitcoin community, gaining momentum at conferences and with a growing user base through its social networks. With its innovative combination of gaming, the Lightning Network, and competitive play, Chain Duel offers a glimpse into the future of Lightning-based gaming.
How LNbits is Used in Chain Duel
Seamless Integration with LNbits
At the core of Chain Duel’s efficient payment processing is LNbits, which handles in-game transactions smoothly and reliably. Chain Duel uses the LNbits LNURL-pay and LNURL-withdraw extensions to manage payments and rewards between players. Before each match, players send satoshis using LNURL-pay, which generates a static QR code or link for making the payment. LNURL-pay allows users to attach a note to the payment, which Chain Duel creatively uses as a way to insert the player name in-game. The simplicity of LNURL-pay ensures that users can quickly and easily initiate games, with fresh invoices being issued for every game. When players win, LNURL-withdraw enables them to seamlessly pull their earnings from the game, providing a quick payout system.
These extensions make it easy for players to send and receive Bitcoin with minimal latency, fully leveraging the power of the Lightning Network for fast and low-cost payments. The flexibility of LNbits’ tools means that game developers don’t need to worry about building custom payment systems from scratch—they can rely on LNbits to handle all financial transactions with precision.
Lightning Tournaments
Chain Duel tournaments leverage LNbits and its LNURL extensions to create a seamless and efficient experience for players. In Chain Duel tournaments, LNbits plays a crucial role in managing the overall economics. LNbits facilitates the generation of LNURL QR codes that participants can scan to register quickly or withdraw their winnings. LNbits allows Chain Duel to automatically handle multiple registrations through LNURL-pay, enabling players to participate in the tournament without additional steps. The Lightning Network's speed ensures that these payments occur in real-time, reducing wait times and allowing for a smoother flow in-game.
Splitting Payments
LNbits further simplifies revenue-sharing within Chain Duel. This feature allows the game to automatically split the satoshis sent by players into different shares for the game’s developer, designer, and host. Each time a payment is made to join a match, LNbits is used to automattically pay each of the contributors, according to pre-defined rules. This automated process ensures that everyone involved in the development and running of the game gets their fair share without manual intervention or complex bookkeeping.
Nostr Integration
Chain Duel also integrates with Nostr, a decentralized protocol for social interactions. Players can join games using "Zaps", small tips or micropayments sent over the Lightning Network within the Nostr ecosystem. Through NIP-57, which enables Nostr clients to request Zap invoices, players can use LNURL-pay enabled Zaps to register in P2P matches, further enhancing the Chain Duel experience. By using Zaps as a way to register in-game, Chain Duel automates the process of fetching players' identity, creating a more competitive and social experience. Zaps are public on the Nostr network, further expanding Chain Duel's games social reach and community engagement.
Game and Payment Synchronization
One of the key reasons Chain Duel developers chose LNbits is its powerful API that connects directly with the game’s logic. LNbits allows the game to synchronize payments with gameplay in real-time, providing a seamless experience where payments are an integrated part of the gaming mechanics.
With LNbits managing both the payment process and the Lightning Network’s complex infrastructure, Chain Duel developers are free to concentrate on enhancing the competitive and Lightning Network-related aspects of the game. This division of tasks is essential for streamlining development while still providing an innovative in-game payment experience that is deeply integrated with the Bitcoin network.
LNbits proves to be an indispensable tool for Chain Duel, enabling smooth in-game transactions, real-time revenue sharing, and seamless integration with Nostr. For developers looking to build Lightning-powered games, LNbits offers a powerful suite of tools that handle everything from micropayments to payment distribution—ensuring that the game's focus remains on fun and competition rather than complex payment systems.
LNBits facilitating Education and Adoption
This system contributes to educating users on the power of the Lightning Network. Since Chain Duel directly involve real satoshis and LNURL for registration and rewards, players actively experience how Lightning can facilitate fast, cheap, and permissionless payments. By incorporating LNbits into Chain Duel, the game serves as an educational tool that introduces users to the benefits of the Lightning Network. Players gain direct experience using Lightning wallets and LNURL, helping them understand how these tools work in real-world scenarios. The near-instant nature of these payments showcases the power of Lightning in a practical context, highlighting its potential beyond just gaming. Players are encouraged to set up wallets, explore the Lightning ecosystem, and eventually become familiar with Bitcoin and Lightning technology. By integrating LNbits, Chain Duel transforms in-game payments into a learning opportunity, making Bitcoin and Lightning more approachable for users worldwide.

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.

2025-05-09 23:10:14I. Historical Foundations of U.S. Monetary Architecture
The early monetary system of the United States was built atop inherited commodity money conventions from Europe’s maritime economies. Silver and gold coins—primarily Spanish pieces of eight, Dutch guilders, and other foreign specie—formed the basis of colonial commerce. These units were already integrated into international trade and piracy networks and functioned with natural compatibility across England, France, Spain, and Denmark. Lacking a centralized mint or formal currency, the U.S. adopted these forms de facto.
As security risks and the practical constraints of physical coinage mounted, banks emerged to warehouse specie and issue redeemable certificates. These certificates evolved into fiduciary media—claims on specie not actually in hand. Banks observed over time that substantial portions of reserves remained unclaimed for years. This enabled fractional reserve banking: issuing more claims than reserves held, so long as redemption demand stayed low. The practice was inherently unstable, prone to panics and bank runs, prompting eventual centralization through the formation of the Federal Reserve in 1913.
Following the Civil War and unstable reinstatements of gold convertibility, the U.S. sought global monetary stability. After World War II, the Bretton Woods system formalized the U.S. dollar as the global reserve currency. The dollar was nominally backed by gold, but most international dollars were held offshore and recycled into U.S. Treasuries. The Nixon Shock of 1971 eliminated the gold peg, converting the dollar into pure fiat. Yet offshore dollar demand remained, sustained by oil trade mandates and the unique role of Treasuries as global reserve assets.
II. The Structure of Fiduciary Media and Treasury Demand
Under this system, foreign trade surpluses with the U.S. generate excess dollars. These surplus dollars are parked in U.S. Treasuries, thereby recycling trade imbalances into U.S. fiscal liquidity. While technically loans to the U.S. government, these purchases act like interest-only transfers—governments receive yield, and the U.S. receives spendable liquidity without principal repayment due in the short term. Debt is perpetually rolled over, rarely extinguished.
This creates an illusion of global subsidy: U.S. deficits are financed via foreign capital inflows that, in practice, function more like financial tribute systems than conventional debt markets. The underlying asset—U.S. Treasury debt—functions as the base reserve asset of the dollar system, replacing gold in post-Bretton Woods monetary logic.
III. Emergence of Tether and the Parastatal Dollar
Tether (USDT), as a private issuer of dollar-denominated tokens, mimics key central bank behaviors while operating outside the regulatory perimeter. It mints tokens allegedly backed 1:1 by U.S. dollars or dollar-denominated securities (mostly Treasuries). These tokens circulate globally, often in jurisdictions with limited banking access, and increasingly serve as synthetic dollar substitutes.
If USDT gains dominance as the preferred medium of exchange—due to technological advantages, speed, programmability, or access—it displaces Federal Reserve Notes (FRNs) not through devaluation, but through functional obsolescence. Gresham’s Law inverts: good money (more liquid, programmable, globally transferable USDT) displaces bad (FRNs) even if both maintain a nominal 1:1 parity.
Over time, this preference translates to a systemic demand shift. Actors increasingly use Tether instead of FRNs, especially in global commerce, digital marketplaces, or decentralized finance. Tether tokens effectively become shadow base money.
IV. Interaction with Commercial Banking and Redemption Mechanics
Under traditional fractional reserve systems, commercial banks issue loans denominated in U.S. dollars, expanding the money supply. When borrowers repay loans, this destroys the created dollars and contracts monetary elasticity. If borrowers repay in USDT instead of FRNs:
- Banks receive a non-Fed liability (USDT).
- USDT is not recognized as reserve-eligible within the Federal Reserve System.
- Banks must either redeem USDT for FRNs, or demand par-value conversion from Tether to settle reserve requirements and balance their books.
This places redemption pressure on Tether and threatens its 1:1 peg under stress. If redemption latency, friction, or cost arises, USDT’s equivalence to FRNs is compromised. Conversely, if banks are permitted or compelled to hold USDT as reserve or regulatory capital, Tether becomes a de facto reserve issuer.
In this scenario, banks may begin demanding loans in USDT, mirroring borrower behavior. For this to occur sustainably, banks must secure Tether liquidity. This creates two options: - Purchase USDT from Tether or on the secondary market, collateralized by existing fiat. - Borrow USDT directly from Tether, using bank-issued debt as collateral.
The latter mirrors Federal Reserve discount window operations. Tether becomes a lender of first resort, providing monetary elasticity to the banking system by creating new tokens against promissory assets—exactly how central banks function.
V. Structural Consequences: Parallel Central Banking
If Tether begins lending to commercial banks, issuing tokens backed by bank notes or collateralized debt obligations: - Tether controls the expansion of broad money through credit issuance. - Its balance sheet mimics a central bank, with Treasuries and bank debt as assets and tokens as liabilities. - It intermediates between sovereign debt and global liquidity demand, replacing the Federal Reserve’s open market operations with its own issuance-redemption cycles.
Simultaneously, if Tether purchases U.S. Treasuries with FRNs received through token issuance, it: - Supplies the Treasury with new liquidity (via bond purchases). - Collects yield on government debt. - Issues a parallel form of U.S. dollars that never require redemption—an interest-only loan to the U.S. government from a non-sovereign entity.
In this context, Tether performs monetary functions of both a central bank and a sovereign wealth fund, without political accountability or regulatory transparency.
VI. Endgame: Institutional Inversion and Fed Redundancy
This paradigm represents an institutional inversion:
- The Federal Reserve becomes a legacy issuer.
- Tether becomes the operational base money provider in both retail and interbank contexts.
- Treasuries remain the foundational reserve asset, but access to them is mediated by a private intermediary.
- The dollar persists, but its issuer changes. The State becomes a fiscal agent of a decentralized financial ecosystem, not its monetary sovereign.
Unless the Federal Reserve reasserts control—either by absorbing Tether, outlawing its instruments, or integrating its tokens into the reserve framework—it risks becoming irrelevant in the daily function of money.
Tether, in this configuration, is no longer a derivative of the dollar—it is the dollar, just one level removed from sovereign control. The future of monetary sovereignty under such a regime is post-national and platform-mediated.

Standard Chartered Backs $500K Bitcoin Target, Citing Growing Government Exposure Through MSTRSovereign investment in Bitcoin is accelerating—just not always in the most direct way. In a new report, Standard Chartered Bank says indirect exposure via Strategy (formerly MicroStrategy) is quietly increasing among government entities, reinforcing the bank’s long-standing price prediction that Bitcoin will reach $500,000 before President Donald Trump leaves office in 2029.

Standard Chartered says SEC 13F fillings support #Bitcoin reaching $500,000 by 2028
pic.twitter.com/MURg9bxLka
— Bitcoin Magazine (@BitcoinMagazine) May 20, 2025
“The latest 13F data from the U.S. Securities and Exchange Commission (SEC) supports our core thesis that Bitcoin (BTC) will reach the $500,000 level before Trump leaves office as it attracts a wider range of institutional buyers,” wrote Geoffrey Kendrick, Standard Chartered’s global head of digital assets research. “As more investors gain access to the asset and as volatility falls, we believe portfolios will migrate towards their optimal level from an underweight starting position in BTC.”
Q1 13F filings revealed a slowdown in direct bitcoin ETF buying—Wisconsin’s state fund exited its entire 3,400 BTC-equivalent IBIT position—while government-linked purchases of MSTR shares were on the rise. Abu Dhabi’s Mubadala, for instance, upped its IBIT exposure to 5,000 BTC equivalent, but Kendrick says the bigger story is elsewhere.
“We believe that in some cases, MSTR holdings by government entities reflect a desire to gain Bitcoin exposure where local regulations do not allow direct BTC holdings,” he said.
France and Saudi Arabia took first-time MSTR positions in Q1. Meanwhile, Norway’s Government Pension Fund, the Swiss National Bank, and South Korea’s public funds each added exposure equivalent to 700 BTC. U.S. retirement funds in states like California and New York added a combined 1,000 BTC equivalent via MSTR. Kendrick called the trend “very encouraging.”
“The quarterly 13F data is the best test of our thesis that BTC will attract new institutional buyer types as the market matures, helping the price reach our USD 500,000 level,” Kendrick said. “When institutions buy Bitcoin, prices tend to rise.”
SEC DATA BACKS BITCOIN $500K TARGET BY 2028: STANDARD CHARTERED
Standard Chartered's Geoff Kendrick says recent SEC 13F filings support a possible rise in Bitcoin to $500,000 by end-2028. While direct ETF holdings dipped in Q1, government entities boosted stakes in Strategy…
— *Walter Bloomberg (@DeItaone) May 20, 2025
This isn’t Kendrick’s first bullish call. Last month, he admitted his prior $120K forecast for Q2 2025 was “too low,” citing surging inflows into U.S. spot BTC ETFs—totaling $5.3 billion over just three weeks. At the time, Kendrick revised his 2025 year-end target to $200,000.
Standard Chartered’s latest analysis shows that Bitcoin’s role in institutional portfolios is maturing beyond tech volatility correlation—now increasingly seen as a macro hedge. “It is now all about flows,” Kendrick said. “And flows are coming in many forms.”

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.”

2025-02-09 16:50:04There has been a good bit of discussion on Nostr over the past few days about the merits of zaps as a method of engaging with notes, so after writing a rather lengthy article on the pros of a strategic Bitcoin reserve, I wanted to take some time to chime in on the much more fun topic of digital engagement.
Let's begin by defining a couple of things:
Nostr is a decentralized, censorship-resistance protocol whose current biggest use case is social media (think Twitter/X). Instead of relying on company servers, it relies on relays that anyone can spin up and own their own content. Its use cases are much bigger, though, and this article is hosted on my own relay, using my own Nostr relay as an example.
Zap is a tip or donation denominated in sats (small units of Bitcoin) sent from one user to another. This is generally done directly over the Lightning Network but is increasingly using Cashu tokens. For the sake of this discussion, how you transmit/receive zaps will be irrelevant, so don't worry if you don't know what Lightning or Cashu are.
If we look at how users engage with posts and follows/followers on platforms like Twitter, Facebook, etc., it becomes evident that traditional social media thrives on engagement farming. The more outrageous a post, the more likely it will get a reaction. We see a version of this on more visual social platforms like YouTube and TikTok that use carefully crafted thumbnail images to grab the user's attention to click the video. If you'd like to dive deep into the psychology and science behind social media engagement, let me know, and I'd be happy to follow up with another article.
In this user engagement model, a user is given the option to comment or like the original post, or share it among their followers to increase its signal. They receive no value from engaging with the content aside from the dopamine hit of the original experience or having their comment liked back by whatever influencer they provide value to. Ad revenue flows to the content creator. Clout flows to the content creator. Sales revenue from merch and content placement flows to the content creator. We call this a linear economy -- the idea that resources get created, used up, then thrown away. Users create content and farm as much engagement as possible, then the content is forgotten within a few hours as they move on to the next piece of content to be farmed.
What if there were a simple way to give value back to those who engage with your content? By implementing some value-for-value model -- a circular economy. Enter zaps.
Unlike traditional social media platforms, Nostr does not actively use algorithms to determine what content is popular, nor does it push content created for active user engagement to the top of a user's timeline. Yes, there are "trending" and "most zapped" timelines that users can choose to use as their default, but these use relatively straightforward engagement metrics to rank posts for these timelines.
That is not to say that we may not see clients actively seeking to refine timeline algorithms for specific metrics. Still, the beauty of having an open protocol with media that is controlled solely by its users is that users who begin to see their timeline gamed towards specific algorithms can choose to move to another client, and for those who are more tech-savvy, they can opt to run their own relays or create their own clients with personalized algorithms and web of trust scoring systems.
Zaps enable the means to create a new type of social media economy in which creators can earn for creating content and users can earn by actively engaging with it. Like and reposting content is relatively frictionless and costs nothing but a simple button tap. Zaps provide active engagement because they signal to your followers and those of the content creator that this post has genuine value, quite literally in the form of money—sats.
I have seen some comments on Nostr claiming that removing likes and reactions is for wealthy people who can afford to send zaps and that the majority of people in the US and around the world do not have the time or money to zap because they have better things to spend their money like feeding their families and paying their bills. While at face value, these may seem like valid arguments, they, unfortunately, represent the brainwashed, defeatist attitude that our current economic (and, by extension, social media) systems aim to instill in all of us to continue extracting value from our lives.
Imagine now, if those people dedicating their own time (time = money) to mine pity points on social media would instead spend that time with genuine value creation by posting content that is meaningful to cultural discussions. Imagine if, instead of complaining that their posts get no zaps and going on a tirade about how much of a victim they are, they would empower themselves to take control of their content and give value back to the world; where would that leave us? How much value could be created on a nascent platform such as Nostr, and how quickly could it overtake other platforms?
Other users argue about user experience and that additional friction (i.e., zaps) leads to lower engagement, as proven by decades of studies on user interaction. While the added friction may turn some users away, does that necessarily provide less value? I argue quite the opposite. You haven't made a few sats from zaps with your content? Can't afford to send some sats to a wallet for zapping? How about using the most excellent available resource and spending 10 seconds of your time to leave a comment? Likes and reactions are valueless transactions. Social media's real value derives from providing monetary compensation and actively engaging in a conversation with posts you find interesting or thought-provoking. Remember when humans thrived on conversation and discussion for entertainment instead of simply being an onlooker of someone else's life?
If you've made it this far, my only request is this: try only zapping and commenting as a method of engagement for two weeks. Sure, you may end up liking a post here and there, but be more mindful of how you interact with the world and break yourself from blind instinct. You'll thank me later.

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."

2025-05-06 14:05:40If you're an engineer stepping into the Bitcoin space from the broader crypto ecosystem, you're probably carrying a mental model shaped by speed, flexibility, and rapid innovation. That makes sense—most blockchain platforms pride themselves on throughput, programmability, and dev agility.
But Bitcoin operates from a different set of first principles. It’s not competing to be the fastest network or the most expressive smart contract platform. It’s aiming to be the most credible, neutral, and globally accessible value layer in human history.
Here’s why that matters—and why Bitcoin is not just an alternative crypto asset, but a structural necessity in the global financial system.
1. Bitcoin Fixes the Triffin Dilemma—Not With Policy, But Protocol
The Triffin Dilemma shows us that any country issuing the global reserve currency must run persistent deficits to supply that currency to the world. That’s not a flaw of bad leadership—it’s an inherent contradiction. The U.S. must debase its own monetary integrity to meet global dollar demand. That’s a self-terminating system.
Bitcoin sidesteps this entirely by being:
- Non-sovereign – no single nation owns it
- Hard-capped – no central authority can inflate it
- Verifiable and neutral – anyone with a full node can enforce the rules
In other words, Bitcoin turns global liquidity into an engineering problem, not a political one. No other system, fiat or crypto, has achieved that.
2. Bitcoin’s “Ossification” Is Intentional—and It's a Feature
From the outside, Bitcoin development may look sluggish. Features are slow to roll out. Code changes are conservative. Consensus rules are treated as sacred.
That’s the point.
When you’re building the global monetary base layer, stability is not a weakness. It’s a prerequisite. Every other financial instrument, app, or protocol that builds on Bitcoin depends on one thing: assurance that the base layer won’t change underneath them without extreme scrutiny.
So-called “ossification” is just another term for predictability and integrity. And when the market does demand change (SegWit, Taproot), Bitcoin’s soft-fork governance process has proven capable of deploying it safely—without coercive central control.
3. Layered Architecture: Throughput Is Not a Base Layer Concern
You don’t scale settlement at the base layer. You build layered systems. Just as TCP/IP doesn't need to carry YouTube traffic directly, Bitcoin doesn’t need to process every microtransaction.
Instead, it anchors:
- Lightning (fast payments)
- Fedimint (community custody)
- Ark (privacy + UTXO compression)
- Statechains, sidechains, and covenants (coming evolution)
All of these inherit Bitcoin’s security and scarcity, while handling volume off-chain, in ways that maintain auditability and self-custody.
4. Universal Assayability Requires Minimalism at the Base Layer
A core design constraint of Bitcoin is that any participant, anywhere in the world, must be able to independently verify the validity of every transaction and block—past and present—without needing permission or relying on third parties.
This property is called assayability—the ability to “test” or verify the authenticity and integrity of received bitcoin, much like verifying the weight and purity of a gold coin.
To preserve this:
- The base layer must remain resource-light, so running a full node stays accessible on commodity hardware.
- Block sizes must remain small enough to prevent centralization of verification.
- Historical data must remain consistent and tamper-evident, enabling proof chains across time and jurisdiction.
Any base layer that scales by increasing throughput or complexity undermines this fundamental guarantee, making the network more dependent on trust and surveillance infrastructure.
Bitcoin prioritizes global verifiability over throughput—because trustless money requires that every user can check the money they receive.
5. Governance: Not Captured, Just Resistant to Coercion
The current controversy around
OP_RETURN
and proposals to limit inscriptions is instructive. Some prominent devs have advocated for changes to block content filtering. Others see it as overreach.Here's what matters:
- No single dev, or team, can force changes into the network. Period.
- Bitcoin Core is not “the source of truth.” It’s one implementation. If it deviates from market consensus, it gets forked, sidelined, or replaced.
- The economic majority—miners, users, businesses—enforce Bitcoin’s rules, not GitHub maintainers.
In fact, recent community resistance to perceived Core overreach only reinforces Bitcoin’s resilience. Engineers who posture with narcissistic certainty, dismiss dissent, or attempt to capture influence are routinely neutralized by the market’s refusal to upgrade or adopt forks that undermine neutrality or openness.
This is governance via credible neutrality and negative feedback loops. Power doesn’t accumulate in one place. It’s constantly checked by the network’s distributed incentives.
6. Bitcoin Is Still in Its Infancy—And That’s a Good Thing
You’re not too late. The ecosystem around Bitcoin—especially L2 protocols, privacy tools, custody innovation, and zero-knowledge integrations—is just beginning.
If you're an engineer looking for:
- Systems with global scale constraints
- Architectures that optimize for integrity, not speed
- Consensus mechanisms that resist coercion
- A base layer with predictable monetary policy
Then Bitcoin is where serious systems engineers go when they’ve outgrown crypto theater.
Take-away
Under realistic, market-aware assumptions—where:
- Bitcoin’s ossification is seen as a stability feature, not inertia,
- Market forces can and do demand and implement change via tested, non-coercive mechanisms,
- Proof-of-work is recognized as the only consensus mechanism resistant to fiat capture,
- Wealth concentration is understood as a temporary distribution effect during early monetization,
- Low base layer throughput is a deliberate design constraint to preserve verifiability and neutrality,
- And innovation is layered by design, with the base chain providing integrity, not complexity...
Then Bitcoin is not a fragile or inflexible system—it is a deliberately minimal, modular, and resilient protocol.
Its governance is not leaderless chaos; it's a negative-feedback structure that minimizes the power of individuals or institutions to coerce change. The very fact that proposals—like controversial OP_RETURN restrictions—can be resisted, forked around, or ignored by the market without breaking the system is proof of decentralized control, not dysfunction.
Bitcoin is an adversarially robust monetary foundation. Its value lies not in how fast it changes, but in how reliably it doesn't—unless change is forced by real, bottom-up demand and implemented through consensus-tested soft forks.
In this framing, Bitcoin isn't a slower crypto. It's the engineering benchmark for systems that must endure, not entertain.
Final Word
Bitcoin isn’t moving slowly because it’s dying. It’s moving carefully because it’s winning. It’s not an app platform or a sandbox. It’s a protocol layer for the future of money.
If you're here because you want to help build that future, you’re in the right place.

2025-02-04 08:29:00President Trump has started rolling out his tariffs, something I blogged about in November. People are talking about these tariffs a lot right now, with many people (correctly) commenting on how consumers will end up with higher prices as a result of these tariffs. While that part is true, I’ve seen a lot of people taking it to the next, incorrect step: that consumers will pay the entirety of the tax. I put up a poll on X to see what people thought, and while the right answer got a lot of votes, it wasn't the winner.
For purposes of this blog post, our ultimate question will be the following:
- Suppose apples currently sell for $1 each in the entire United States.
- There are domestic sellers and foreign sellers of apples, all receiving the same price.
- There are no taxes or tariffs on the purchase of apples.
- The question is: if the US federal government puts a $0.50 import tariff per apple, what will be the change in the following:
- Number of apples bought in the US
- Price paid by buyers for apples in the US
- Post-tax price received by domestic apple producers
- Post-tax price received by foreign apple producers
Before we can answer that question, we need to ask an easier, first question: before instituting the tariff, why do apples cost $1?
And finally, before we dive into the details, let me provide you with the answers to the ultimate question. I recommend you try to guess these answers before reading this, and if you get it wrong, try to understand why:
- The number of apples bought will go down
- The buyers will pay more for each apple they buy, but not the full amount of the tariff
- Domestic apple sellers will receive a higher price per apple
- Foreign apple sellers will receive a lower price per apple, but not lowered by the full amount of the tariff
In other words, regardless of who sends the payment to the government, both taxed parties (domestic buyers and foreign sellers) will absorb some of the costs of the tariff, while domestic sellers will benefit from the protectionism provided by tariffs and be able to sell at a higher price per unit.
Marginal benefit
All of the numbers discussed below are part of a helper Google Sheet I put together for this analysis. Also, apologies about the jagged lines in the charts below, I hadn’t realized before starting on this that there are some difficulties with creating supply and demand charts in Google Sheets.
Let’s say I absolutely love apples, they’re my favorite food. How much would I be willing to pay for a single apple? You might say “$1, that’s the price in the supermarket,” and in many ways you’d be right. If I walk into supermarket A, see apples on sale for $50, and know that I can buy them at supermarket B for $1, I’ll almost certainly leave A and go buy at B.
But that’s not what I mean. What I mean is: how high would the price of apples have to go everywhere so that I’d no longer be willing to buy a single apple? This is a purely personal, subjective opinion. It’s impacted by how much money I have available, other expenses I need to cover, and how much I like apples. But let’s say the number is $5.
How much would I be willing to pay for another apple? Maybe another $5. But how much am I willing to pay for the 1,000th apple? 10,000th? At some point, I’ll get sick of apples, or run out of space to keep the apples, or not be able to eat, cook, and otherwise preserve all those apples before they rot.
The point being: I’ll be progressively willing to spend less and less money for each apple. This form of analysis is called marginal benefit: how much benefit (expressed as dollars I’m willing to spend) will I receive from each apple? This is a downward sloping function: for each additional apple I buy (quantity demanded), the price I’m willing to pay goes down. This is what gives my personal demand curve. And if we aggregate demand curves across all market participants (meaning: everyone interested in buying apples), we end up with something like this:
Assuming no changes in people’s behavior and other conditions in the market, this chart tells us how many apples will be purchased by our buyers at each price point between $0.50 and $5. And ceteris paribus (all else being equal), this will continue to be the demand curve for apples.
Marginal cost
Demand is half the story of economics. The other half is supply, or: how many apples will I sell at each price point? Supply curves are upward sloping: the higher the price, the more a person or company is willing and able to sell a product.
Let’s understand why. Suppose I have an apple orchard. It’s a large property right next to my house. With about 2 minutes of effort, I can walk out of my house, find the nearest tree, pick 5 apples off the tree, and call it a day. 5 apples for 2 minutes of effort is pretty good, right?
Yes, there was all the effort necessary to buy the land, and plant the trees, and water them… and a bunch more than I likely can’t even guess at. We’re going to ignore all of that for our analysis, because for short-term supply-and-demand movement, we can ignore these kinds of sunk costs. One other simplification: in reality, supply curves often start descending before ascending. This accounts for achieving efficiencies of scale after the first number of units purchased. But since both these topics are unneeded for understanding taxes, I won’t go any further.
Anyway, back to my apple orchard. If someone offers me $0.50 per apple, I can do 2 minutes of effort and get $2.50 in revenue, which equates to a $75/hour wage for me. I’m more than happy to pick apples at that price!
However, let’s say someone comes to buy 10,000 apples from me instead. I no longer just walk out to my nearest tree. I’m going to need to get in my truck, drive around, spend the day in the sun, pay for gas, take a day off of my day job (let’s say it pays me $70/hour). The costs go up significantly. Let’s say it takes 5 days to harvest all those apples myself, it costs me $100 in fuel and other expenses, and I lose out on my $70/hour job for 5 days. We end up with:
- Total expenditure: $100 + $70 * 8 hours a day * 5 days \== $2900
- Total revenue: $5000 (10,000 apples at $0.50 each)
- Total profit: $2100
So I’m still willing to sell the apples at this price, but it’s not as attractive as before. And as the number of apples purchased goes up, my costs keep increasing. I’ll need to spend more money on fuel to travel more of my property. At some point I won’t be able to do the work myself anymore, so I’ll need to pay others to work on the farm, and they’ll be slower at picking apples than me (less familiar with the property, less direct motivation, etc.). The point being: at some point, the number of apples can go high enough that the $0.50 price point no longer makes me any money.
This kind of analysis is called marginal cost. It refers to the additional amount of expenditure a seller has to spend in order to produce each additional unit of the good. Marginal costs go up as quantity sold goes up. And like demand curves, if you aggregate this data across all sellers, you get a supply curve like this:
Equilibrium price
We now know, for every price point, how many apples buyers will purchase, and how many apples sellers will sell. Now we find the equilibrium: where the supply and demand curves meet. This point represents where the marginal benefit a buyer would receive from the next buyer would be less than the cost it would take the next seller to make it. Let’s see it in a chart:
You’ll notice that these two graphs cross at the $1 price point, where 63 apples are both demanded (bought by consumers) and supplied (sold by producers). This is our equilibrium price. We also have a visualization of the surplus created by these trades. Everything to the left of the equilibrium point and between the supply and demand curves represents surplus: an area where someone is receiving something of more value than they give. For example:
- When I bought my first apple for $1, but I was willing to spend $5, I made $4 of consumer surplus. The consumer portion of the surplus is everything to the left of the equilibrium point, between the supply and demand curves, and above the equilibrium price point.
- When a seller sells his first apple for $1, but it only cost $0.50 to produce it, the seller made $0.50 of producer surplus. The producer portion of the surplus is everything to the left of the equilibrium point, between the supply and demand curves, and below the equilibrium price point.
Another way of thinking of surplus is “every time someone got a better price than they would have been willing to take.”
OK, with this in place, we now have enough information to figure out how to price in the tariff, which we’ll treat as a negative externality.
Modeling taxes
Alright, the government has now instituted a $0.50 tariff on every apple sold within the US by a foreign producer. We can generally model taxes by either increasing the marginal cost of each unit sold (shifting the supply curve up), or by decreasing the marginal benefit of each unit bought (shifting the demand curve down). In this case, since only some of the producers will pay the tax, it makes more sense to modify the supply curve.
First, let’s see what happens to the foreign seller-only supply curve when you add in the tariff:
With the tariff in place, for each quantity level, the price at which the seller will sell is $0.50 higher than before the tariff. That makes sense: if I was previously willing to sell my 82nd apple for $3, I would now need to charge $3.50 for that apple to cover the cost of the tariff. We see this as the tariff “pushing up” or “pushing left” the original supply curve.
We can add this new supply curve to our existing (unchanged) supply curve for domestic-only sellers, and we end up with a result like this:
The total supply curve adds up the individual foreign and domestic supply curves. At each price point, we add up the total quantity each group would be willing to sell to determine the total quantity supplied for each price point. Once we have that cumulative supply curve defined, we can produce an updated supply-and-demand chart including the tariff:
As we can see, the equilibrium has shifted:
- The equilibrium price paid by consumers has risen from $1 to $1.20.
- The total number of apples purchased has dropped from 63 apples to 60 apples.
- Consumers therefore received 3 less apples. They spent $72 for these 60 apples, whereas previously they spent $63 for 3 more apples, a definite decrease in consumer surplus.
- Foreign producers sold 36 of those apples (see the raw data in the linked Google Sheet), for a gross revenue of $43.20. However, they also need to pay the tariff to the US government, which accounts for $18, meaning they only receive $25.20 post-tariff. Previously, they sold 42 apples at $1 each with no tariff to be paid, meaning they took home $42.
- Domestic producers sold the remaining 24 apples at $1.20, giving them a revenue of $28.80. Since they don’t pay the tariff, they take home all of that money. By contrast, previously, they sold 21 apples at $1, for a take-home of $21.
- The government receives $0.50 for each of the 60 apples sold, or in other words receives $30 in revenue it wouldn’t have received otherwise.
We could be more specific about the surpluses, and calculate the actual areas for consumer surplus, producer surplus, inefficiency from the tariff, and government revenue from the tariff. But I won’t bother, as those calculations get slightly more involved. Instead, let’s just look at the aggregate outcomes:
- Consumers were unquestionably hurt. Their price paid went up by $0.20 per apple, and received less apples.
- Foreign producers were also hurt. Their price received went down from the original $1 to the new post-tariff price of $1.20, minus the $0.50 tariff. In other words: foreign producers only receive $0.70 per apple now. This hurt can be mitigated by shifting sales to other countries without a tariff, but the pain will exist regardless.
- Domestic producers scored. They can sell less apples and make more revenue doing it.
- And the government walked away with an extra $30.
Hopefully you now see the answer to the original questions. Importantly, while the government imposed a $0.50 tariff, neither side fully absorbed that cost. Consumers paid a bit more, foreign producers received a bit less. The exact details of how that tariff was split across the groups is mediated by the relevant supply and demand curves of each group. If you want to learn more about this, the relevant search term is “price elasticity,” or how much a group’s quantity supplied or demanded will change based on changes in the price.
Other taxes
Most taxes are some kind of a tax on trade. Tariffs on apples is an obvious one. But the same applies to income tax (taxing the worker for the trade of labor for money) or payroll tax (same thing, just taxing the employer instead). Interestingly, you can use the same model for analyzing things like tax incentives. For example, if the government decided to subsidize domestic apple production by giving the domestic producers a $0.50 bonus for each apple they sell, we would end up with a similar kind of analysis, except instead of the foreign supply curve shifting up, we’d see the domestic supply curve shifting down.
And generally speaking, this is what you’ll always see with government involvement in the economy. It will result in disrupting an existing equilibrium, letting the market readjust to a new equilibrium, and incentivization of some behavior, causing some people to benefit and others to lose out. We saw with the apple tariff, domestic producers and the government benefited while others lost.
You can see the reverse though with tax incentives. If I give a tax incentive of providing a deduction (not paying income tax) for preschool, we would end up with:
- Government needs to make up the difference in tax revenue, either by raising taxes on others or printing more money (leading to inflation). Either way, those paying the tax or those holding government debased currency will pay a price.
- Those people who don’t use the preschool deduction will receive no benefit, so they simply pay a cost.
- Those who do use the preschool deduction will end up paying less on tax+preschool than they would have otherwise.
This analysis is fully amoral. It’s not saying whether providing subsidized preschool is a good thing or not, it simply tells you where the costs will be felt, and points out that such government interference in free economic choice does result in inefficiencies in the system. Once you have that knowledge, you’re more well educated on making a decision about whether the costs of government intervention are worth the benefits.

@ 97c70a44:ad98e322
2025-01-30 17:15:37There was a slight dust up recently over a website someone runs removing a listing for an app someone built based on entirely arbitrary criteria. I'm not to going to attempt to speak for either wounded party, but I would like to share my own personal definition for what constitutes a "nostr app" in an effort to help clarify what might be an otherwise confusing and opaque purity test.
In this post, I will be committing the "no true Scotsman" fallacy, in which I start with the most liberal definition I can come up with, and gradually refine it until all that is left is the purest, gleamingest, most imaginary and unattainable nostr app imaginable. As I write this, I wonder if anything built yet will actually qualify. In any case, here we go.
It uses nostr
The lowest bar for what a "nostr app" might be is an app ("application" - i.e. software, not necessarily a native app of any kind) that has some nostr-specific code in it, but which doesn't take any advantage of what makes nostr distinctive as a protocol.
Examples might include a scraper of some kind which fulfills its charter by fetching data from relays (regardless of whether it validates or retains signatures). Another might be a regular web 2.0 app which provides an option to "log in with nostr" by requesting and storing the user's public key.
In either case, the fact that nostr is involved is entirely neutral. A scraper can scrape html, pdfs, jsonl, whatever data source - nostr relays are just another target. Likewise, a user's key in this scenario is treated merely as an opaque identifier, with no appreciation for the super powers it brings along.
In most cases, this kind of app only exists as a marketing ploy, or less cynically, because it wants to get in on the hype of being a "nostr app", without the developer quite understanding what that means, or having the budget to execute properly on the claim.
It leverages nostr
Some of you might be wondering, "isn't 'leverage' a synonym for 'use'?" And you would be right, but for one connotative difference. It's possible to "use" something improperly, but by definition leverage gives you a mechanical advantage that you wouldn't otherwise have. This is the second category of "nostr app".
This kind of app gets some benefit out of the nostr protocol and network, but in an entirely selfish fashion. The intention of this kind of app is not to augment the nostr network, but to augment its own UX by borrowing some nifty thing from the protocol without really contributing anything back.
Some examples might include:
- Using nostr signers to encrypt or sign data, and then store that data on a proprietary server.
- Using nostr relays as a kind of low-code backend, but using proprietary event payloads.
- Using nostr event kinds to represent data (why), but not leveraging the trustlessness that buys you.
An application in this category might even communicate to its users via nostr DMs - but this doesn't make it a "nostr app" any more than a website that emails you hot deals on herbal supplements is an "email app". These apps are purely parasitic on the nostr ecosystem.
In the long-term, that's not necessarily a bad thing. Email's ubiquity is self-reinforcing. But in the short term, this kind of "nostr app" can actually do damage to nostr's reputation by over-promising and under-delivering.
It complements nostr
Next up, we have apps that get some benefit out of nostr as above, but give back by providing a unique value proposition to nostr users as nostr users. This is a bit of a fine distinction, but for me this category is for apps which focus on solving problems that nostr isn't good at solving, leaving the nostr integration in a secondary or supporting role.
One example of this kind of app was Mutiny (RIP), which not only allowed users to sign in with nostr, but also pulled those users' social graphs so that users could send money to people they knew and trusted. Mutiny was doing a great job of leveraging nostr, as well as providing value to users with nostr identities - but it was still primarily a bitcoin wallet, not a "nostr app" in the purest sense.
Other examples are things like Nostr Nests and Zap.stream, whose core value proposition is streaming video or audio content. Both make great use of nostr identities, data formats, and relays, but they're primarily streaming apps. A good litmus test for things like this is: if you got rid of nostr, would it be the same product (even if inferior in certain ways)?
A similar category is infrastructure providers that benefit nostr by their existence (and may in fact be targeted explicitly at nostr users), but do things in a centralized, old-web way; for example: media hosts, DNS registrars, hosting providers, and CDNs.
To be clear here, I'm not casting aspersions (I don't even know what those are, or where to buy them). All the apps mentioned above use nostr to great effect, and are a real benefit to nostr users. But they are not True Scotsmen.
It embodies nostr
Ok, here we go. This is the crème de la crème, the top du top, the meilleur du meilleur, the bee's knees. The purest, holiest, most chaste category of nostr app out there. The apps which are, indeed, nostr indigitate.
This category of nostr app (see, no quotes this time) can be defined by the converse of the previous category. If nostr was removed from this type of application, would it be impossible to create the same product?
To tease this apart a bit, apps that leverage the technical aspects of nostr are dependent on nostr the protocol, while apps that benefit nostr exclusively via network effect are integrated into nostr the network. An app that does both things is working in symbiosis with nostr as a whole.
An app that embraces both nostr's protocol and its network becomes an organic extension of every other nostr app out there, multiplying both its competitive moat and its contribution to the ecosystem:
- In contrast to apps that only borrow from nostr on the technical level but continue to operate in their own silos, an application integrated into the nostr network comes pre-packaged with existing users, and is able to provide more value to those users because of other nostr products. On nostr, it's a good thing to advertise your competitors.
- In contrast to apps that only market themselves to nostr users without building out a deep integration on the protocol level, a deeply integrated app becomes an asset to every other nostr app by becoming an organic extension of them through interoperability. This results in increased traffic to the app as other developers and users refer people to it instead of solving their problem on their own. This is the "micro-apps" utopia we've all been waiting for.
Credible exit doesn't matter if there aren't alternative services. Interoperability is pointless if other applications don't offer something your app doesn't. Marketing to nostr users doesn't matter if you don't augment their agency as nostr users.
If I had to choose a single NIP that represents the mindset behind this kind of app, it would be NIP 89 A.K.A. "Recommended Application Handlers", which states:
Nostr's discoverability and transparent event interaction is one of its most interesting/novel mechanics. This NIP provides a simple way for clients to discover applications that handle events of a specific kind to ensure smooth cross-client and cross-kind interactions.
These handlers are the glue that holds nostr apps together. A single event, signed by the developer of an application (or by the application's own account) tells anyone who wants to know 1. what event kinds the app supports, 2. how to link to the app (if it's a client), and (if the pubkey also publishes a kind 10002), 3. which relays the app prefers.
As a sidenote, NIP 89 is currently focused more on clients, leaving DVMs, relays, signers, etc somewhat out in the cold. Updating 89 to include tailored listings for each kind of supporting app would be a huge improvement to the protocol. This, plus a good front end for navigating these listings (sorry nostrapp.link, close but no cigar) would obviate the evil centralized websites that curate apps based on arbitrary criteria.
Examples of this kind of app obviously include many kind 1 clients, as well as clients that attempt to bring the benefits of the nostr protocol and network to new use cases - whether long form content, video, image posts, music, emojis, recipes, project management, or any other "content type".
To drill down into one example, let's think for a moment about forms. What's so great about a forms app that is built on nostr? Well,
- There is a spec for forms and responses, which means that...
- Multiple clients can implement the same data format, allowing for credible exit and user choice, even of...
- Other products not focused on forms, which can still view, respond to, or embed forms, and which can send their users via NIP 89 to a client that does...
- Cryptographically sign forms and responses, which means they are self-authenticating and can be sent to...
- Multiple relays, which reduces the amount of trust necessary to be confident results haven't been deliberately "lost".
Show me a forms product that does all of those things, and isn't built on nostr. You can't, because it doesn't exist. Meanwhile, there are plenty of image hosts with APIs, streaming services, and bitcoin wallets which have basically the same levels of censorship resistance, interoperability, and network effect as if they weren't built on nostr.
It supports nostr
Notice I haven't said anything about whether relays, signers, blossom servers, software libraries, DVMs, and the accumulated addenda of the nostr ecosystem are nostr apps. Well, they are (usually).
This is the category of nostr app that gets none of the credit for doing all of the work. There's no question that they qualify as beautiful nostrcorns, because their value propositions are entirely meaningless outside of the context of nostr. Who needs a signer if you don't have a cryptographic identity you need to protect? DVMs are literally impossible to use without relays. How are you going to find the blossom server that will serve a given hash if you don't know which servers the publishing user has selected to store their content?
In addition to being entirely contextualized by nostr architecture, this type of nostr app is valuable because it does things "the nostr way". By that I mean that they don't simply try to replicate existing internet functionality into a nostr context; instead, they create entirely new ways of putting the basic building blocks of the internet back together.
A great example of this is how Nostr Connect, Nostr Wallet Connect, and DVMs all use relays as brokers, which allows service providers to avoid having to accept incoming network connections. This opens up really interesting possibilities all on its own.
So while I might hesitate to call many of these things "apps", they are certainly "nostr".
Appendix: it smells like a NINO
So, let's say you've created an app, but when you show it to people they politely smile, nod, and call it a NINO (Nostr In Name Only). What's a hacker to do? Well, here's your handy-dandy guide on how to wash that NINO stench off and Become a Nostr.
You app might be a NINO if:
- There's no NIP for your data format (or you're abusing NIP 78, 32, etc by inventing a sub-protocol inside an existing event kind)
- There's a NIP, but no one knows about it because it's in a text file on your hard drive (or buried in your project's repository)
- Your NIP imposes an incompatible/centralized/legacy web paradigm onto nostr
- Your NIP relies on trusted third (or first) parties
- There's only one implementation of your NIP (yours)
- Your core value proposition doesn't depend on relays, events, or nostr identities
- One or more relay urls are hard-coded into the source code
- Your app depends on a specific relay implementation to work (ahem, relay29)
- You don't validate event signatures
- You don't publish events to relays you don't control
- You don't read events from relays you don't control
- You use legacy web services to solve problems, rather than nostr-native solutions
- You use nostr-native solutions, but you've hardcoded their pubkeys or URLs into your app
- You don't use NIP 89 to discover clients and services
- You haven't published a NIP 89 listing for your app
- You don't leverage your users' web of trust for filtering out spam
- You don't respect your users' mute lists
- You try to "own" your users' data
Now let me just re-iterate - it's ok to be a NINO. We need NINOs, because nostr can't (and shouldn't) tackle every problem. You just need to decide whether your app, as a NINO, is actually contributing to the nostr ecosystem, or whether you're just using buzzwords to whitewash a legacy web software product.
If you're in the former camp, great! If you're in the latter, what are you waiting for? Only you can fix your NINO problem. And there are lots of ways to do this, depending on your own unique situation:
- Drop nostr support if it's not doing anyone any good. If you want to build a normal company and make some money, that's perfectly fine.
- Build out your nostr integration - start taking advantage of webs of trust, self-authenticating data, event handlers, etc.
- Work around the problem. Think you need a special relay feature for your app to work? Guess again. Consider encryption, AUTH, DVMs, or better data formats.
- Think your idea is a good one? Talk to other devs or open a PR to the nips repo. No one can adopt your NIP if they don't know about it.
- Keep going. It can sometimes be hard to distinguish a research project from a NINO. New ideas have to be built out before they can be fully appreciated.
- Listen to advice. Nostr developers are friendly and happy to help. If you're not sure why you're getting traction, ask!
I sincerely hope this article is useful for all of you out there in NINO land. Maybe this made you feel better about not passing the totally optional nostr app purity test. Or maybe it gave you some actionable next steps towards making a great NINON (Nostr In Not Only Name) app. In either case, GM and PV.

A once-functional object, now eroded by time and human intervention, stripped of its original purpose. Layers of presence accumulate—marks, alterations, traces of intent—until the very essence is obscured. Restoration is paradoxical: to reclaim, one must erase. Yet erasure is an impossibility, for to remove these imprints is to deny the existence of those who shaped them.
The work stands as a meditation on entropy, memory, and the irreversible dialogue between creation and decay.

2025-05-20 14:07:47Recentemente tive conhecimento do mais recente flagelo cuja popularidade espelha bem o estado avançado de degeneração da nossa sociedade, o bebé reborn. Há uns anos certamente não passaria de uma piada de mau gosto quando alguém nos dissesse que decidiu adquirir um boneco para criar como se se tratasse de um filho, infelizmente em 2025 deixou de ser uma piada para se tornar algo assombroso.
Depois de fazer alguma pesquisa sobre o tema percebi que há pessoas que têm em curso processos litigantes judiciais relativos à, note-se com pasmo, guarda da boneca. A insanidade não fica por aqui uma vez que, algumas "mães" procuram atendimento médico para os seus bonecos. No Brasil, a câmara dos deputados recebeu três projetos destinados à criação de políticas públicas relacionadas com estes bonecos. As notícias sobre este fenómeno surreal multiplicam-se à medida que a insanidade se alastra como vírus pelas redes sociais.
Vivemos numa sociedade que há muito se divorciou da realidade, uma sociedade de pós-verdade, por isso de alguma forma não choca que este tipo de coisa possa acontecer. Podemos dizer que de alguma forma existe um primado do sentimento face à razão, preferimos, por vezes com consequências catastróficas, uma mentira "empática" do que uma verdade salvífica. Esta nossa tibieza em afirmar a verdade leva-nos consequentemente a uma crendice insustentável que é esta de, cada um tem a sua verdade. Graças a essa filosofia permitimos que um certo discurso lunático tenha mais alcance no espaço público. Por vezes ingenuamente podemos pensar que se trata de algo inofensivo, sem consequências de maior, contudo a experiência mostra-nos precisamente o contrário. Há por detrás destes fenómenos uma índole corrosiva que funciona como aguilhão para a disseminação das agendas políticas e ideológicas que visam a destruição da família. Considerando a excecional vulnerabilidade psíquica que observamos em cada vez mais pessoas neste tempo e a ampla disseminação destes fenómenos temos razão mais que suficientes para estarmos preocupados.
Uma outra elação que podemos retirar é que a nossa sociedade com as alegadas gerações "mais bem preparadas de sempre" está claramente a produzir um excesso de adultos que se comporta e, a todos os títulos são, crianças funcionais.
Com tudo isto fica cada vez mais difícil viver uma vida harmoniosa com a lei natural, pois vivemos em harmonia com algo considerado opressor pelos apologetas destes produtos do marxismo cultural. Com a pretensa igualdade que se pretende alcançar, equiparando inclusive um boneco a uma bebé, as famílias no sentido próprio do termo ficam em segundo plano relativamente a estes "novos" e esotéricos conceitos de família.
Importa perguntar, no meio de todas essas novas formas de se pensar uma família, qual é o ideal ?
Provavelmente os apologetas destas bizarrices ficarão em silêncio uma vez que coerentemente consideram que todas as formas são iguais e válidas.
Isto é apenas mais um sinal que nos é dado do declínio palpável dos valores que construíram a nossa sociedade e civilização. Façamos algo para que estas nocivas ideologias não entrem no nosso coração e em nossas casas, sob pena da corrupção dos nossos princípios e dos daqueles que nos são queridos. Estes fenómenos são de tal forma doentios que nos levam a crer que vivemos numa época tragicómica, o que me fez lembrar de uma história contada por Kierkgaard e que partilho de seguida.
“Certa vez, houve um incêndio num circo ambulante na Dinamarca. O director mandou imediatamente o palhaço, que já se encontrava vestido e maquilhado a preceito, para a vila mais próxima, à procura de ajuda, advertindo-o de que existia o perigo de o fogo se espalhar pelos campos ceifados e ressequidos, com risco iminente para as casas do próprio povoado. O palhaço correu até à vila e pediu aos moradores que viessem ajudar a apagar o incêndio que estava a destruir o circo. Mas os habitantes viram nos gritos do palhaço apenas um belo truque de publicidade que visaria levá-los a acorrer em grande número às sessões do circo; aplaudiam e desatavam a rir. Diante dessa reacção, o palhaço sentiu mais vontade de chorar do que de rir. Fez de tudo para convencer as pessoas de que não estava a representar, de que não se tratava de um truque e sim de um apelo da maior seriedade: estava realmente em causa um incêndio. Mas a sua insistência só fazia aumentar os risos; eles achavam que a performance estava excelente – até que o fogo alcançou de facto aquela vila. Aí já foi tarde, e o fogo acabou por destruir não só o circo, mas também a povoação”.

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... 😏

2025-05-20 14:22:05Ikigai means "the meaning of life" or "the reason for being." Why were we born? What are we living for? When work is not seen as something separate from life.
The Japanese believe that everyone has their own ikigai. Those who discover it find meaning and value in life, leading to greater happiness, better moods, and a more fulfilling world.
Today, there are many books about ikigai, but the first one written by a Japanese author is:
“The Little Book of Ikigai: The Secret Japanese Way to Live a Happy and Long Life” by Ken Mogi (Thai translation by Wuttichai Krisanaprakankit)
Come explore the true world of ikigai through this Japanese neuroscientist’s insights, conveyed through conversations that challenge the idea of ikigai as something grand—showing instead that it starts with small personal joys.
Ken Mogi says that Jiro Ono, a 94-year-old sushi chef who still makes sushi today, was his inspiration for writing the book.
This sushi chef did not start the job out of passion or talent—but he dedicated every piece of sushi to bring happiness to his customers. That, Ken says, is the essence of ikigai.
Strangely, the word “ikigai” is not often used in daily conversations in Japan.
Because it’s something so natural that it doesn’t need to be said. In today’s world, we often talk about how to succeed, how to get promoted, how to become a CEO. But for the Japanese, success isn’t everything.
For example, many Japanese people are deeply passionate about hobbies or have kodawari. Others might not care what those hobbies are—as long as the person seems happy, that’s enough. Some are obsessed with trains, manga, or anime. These people don’t need fame or recognition from society. If they’re happy in their own way, that’s perfectly okay.
Kodawari means a deep dedication or meticulous attention to something. For example, someone obsessed with stationery might spend a lot of time selecting the perfect pens, notebooks, or pencils. They’ll research, analyze, and experiment to find the tools they love most.
Everyone’s ikigai can be different, because people value different things and live differently.
Ikigai is about diversity. Japanese society encourages children to discover their own ikigai. They don’t tell kids to pursue jobs only because they pay well. If you ask students what jobs they want, they rarely say it’s about money first.
Ikigai is not the same as "success." The Japanese know that life isn’t just about being successful. Ikigai matters more. You could be successful but lack ikigai. Conversely, you might not be “successful” but still have ikigai—and you might be happier.
Ken Mogi defines success as something society acknowledges and rewards. But ikigai comes from your own heart and personal happiness. Others may not recognize it as success, but that doesn’t matter.
Ikigai is personal. We can be happy in our own way. We don’t judge others’ happiness—let them find joy in their own path.
The key to ikigai is finding small moments of happiness, even from little things. For example, when Ken was a child, he loved studying butterflies. Now, when he’s out jogging and sees a beautiful butterfly, he feels ikigai. Or sometimes, it comes from small amusing moments—like hearing a child tell his dad, “Dad, you have to do it this way!”
So, if we want to find our own ikigai, where do we start? Start with noticing small pleasures in daily life. That’s the easiest place to begin.
In the brain, there's a chemical called dopamine. When we achieve even small things, dopamine is released, creating happiness. That’s why enjoying small things is so important.
For some, ikigai might seem hard to grasp—especially if life is difficult, if they feel hopeless or lack self-worth. So begin with tiny moments of joy.
Is it the same as positive thinking? Ikigai is a part of that. But when we talk about “positive thinking,” it can feel like pressure to some people. So instead, just notice small joys: making your morning coffee, running in the rain.
Lessons from Ken Mogi:
-
Ikigai is not about chasing success or wealth, but about feeling happiness in your own life, which gives your life personal meaning.
-
Ikigai is not defined by society. Everyone’s ikigai is different. Each person can be happy in their own way.
-
**Don’t judge or force others—**children, partners—to live how you think is right. Respect diversity.
-
Smile at people who are enjoying their ikigai, and support them if they struggle.
-
Ikigai exists on two levels:
-
Big ikigai: life purpose or work values.
-
Small ikigai: tiny joys in everyday life.
-
Ikigai starts with noticing small pleasures today.

2025-05-05 14:25:28Introduction: The Power of Fiction and the Shaping of Collective Morality
Stories define the moral landscape of a civilization. From the earliest mythologies to the modern spectacle of global cinema, the tales a society tells its youth shape the parameters of acceptable behavior, the cost of transgression, and the meaning of justice, power, and redemption. Among the most globally influential narratives of the past half-century is the Star Wars saga, a sprawling science fiction mythology that has transcended genre to become a cultural religion for many. Central to this mythos is the arc of Anakin Skywalker, the fallen Jedi Knight who becomes Darth Vader. In Star Wars: Episode III – Revenge of the Sith, Anakin commits what is arguably the most morally abhorrent act depicted in mainstream popular cinema: the mass murder of children. And yet, by the end of the saga, he is redeemed.
This chapter introduces the uninitiated to the events surrounding this narrative turn and explores the deep structural and ethical concerns it raises. We argue that the cultural treatment of Darth Vader as an anti-hero, even a role model, reveals a deep perversion in the collective moral grammar of the modern West. In doing so, we consider the implications this mythology may have on young adults navigating identity, masculinity, and agency in a world increasingly shaped by spectacle and symbolic narrative.
Part I: The Scene and Its Context
In Revenge of the Sith (2005), the third episode of the Star Wars prequel trilogy, the protagonist Anakin Skywalker succumbs to fear, ambition, and manipulation. Convinced that the Jedi Council is plotting against the Republic and desperate to save his pregnant wife from a vision of death, Anakin pledges allegiance to Chancellor Palpatine, secretly the Sith Lord Darth Sidious. Upon doing so, he is given a new name—Darth Vader—and tasked with a critical mission: to eliminate all Jedi in the temple, including its youngest members.
In one of the most harrowing scenes in the film, Anakin enters the Jedi Temple. A group of young children, known as "younglings," emerge from hiding and plead for help. One steps forward, calling him "Master Skywalker," and asks what they are to do. Anakin responds by igniting his lightsaber. The screen cuts away, but the implication is unambiguous. Later, it is confirmed through dialogue and visual allusion that he slaughtered them all.
There is no ambiguity in the storytelling. The man who will become the galaxy’s most feared enforcer begins his descent by murdering defenseless children.
Part II: A New Kind of Evil in Youth-Oriented Media
For decades, cinema avoided certain taboos. Even films depicting war, genocide, or psychological horror rarely crossed the line into showing children as victims of deliberate violence by the protagonist. When children were harmed, it was by monstrous antagonists, supernatural forces, or offscreen implications. The killing of children was culturally reserved for historical atrocities and horror tales.
In Revenge of the Sith, this boundary was broken. While the film does not show the violence explicitly, the implication is so clear and so central to the character arc that its omission from visual depiction does not blunt the narrative weight. What makes this scene especially jarring is the tonal dissonance between the gravity of the act and the broader cultural treatment of Star Wars as a family-friendly saga. The juxtaposition of child-targeted marketing with a central plot involving child murder is not accidental—it reflects a deeper narrative and commercial structure.
This scene was not a deviation from the arc. It was the intended turning point.
Part III: Masculinity, Militarism, and the Appeal of the Anti-Hero
Darth Vader has long been idolized as a masculine icon. His towering presence, emotionless control, and mechanical voice exude power and discipline. Military institutions have quoted him. He is celebrated in memes, posters, and merchandise. Within the cultural imagination, he embodies dominance, command, and strategic ruthlessness.
For many young men, particularly those struggling with identity, agency, and perceived weakness, Vader becomes more than a character. He becomes an archetype: the man who reclaims power by embracing discipline, forsaking emotion, and exacting vengeance against those who betrayed him. The emotional pain that leads to his fall mirrors the experiences of isolation and perceived emasculation that many young men internalize in a fractured society.
The symbolism becomes dangerous. Anakin's descent into mass murder is portrayed not as the outcome of unchecked cruelty, but as a tragic mistake rooted in love and desperation. The implication is that under enough pressure, even the most horrific act can be framed as a step toward a noble end.
Part IV: Redemption as Narrative Alchemy
By the end of the original trilogy (Return of the Jedi, 1983), Darth Vader kills the Emperor to save his son Luke and dies shortly thereafter. Luke mourns him, honors him, and burns his body in reverence. In the final scene, Vader's ghost appears alongside Obi-Wan Kenobi and Yoda—the very men who once considered him the greatest betrayal of their order. He is welcomed back.
There is no reckoning. No mention of the younglings. No memorial to the dead. No consequence beyond his own internal torment.
This model of redemption is not uncommon in Western storytelling. In Christian doctrine, the concept of grace allows for any sin to be forgiven if the sinner repents sincerely. But in the context of secular mass culture, such redemption without justice becomes deeply troubling. The cultural message is clear: even the worst crimes can be erased if one makes a grand enough gesture at the end. It is the erasure of moral debt by narrative fiat.
The implication is not only that evil can be undone by good, but that power and legacy matter more than the victims. Vader is not just forgiven—he is exalted.
Part V: Real-World Reflections and Dangerous Scripts
In recent decades, the rise of mass violence in schools and public places has revealed a disturbing pattern: young men who feel alienated, betrayed, or powerless adopt mythic narratives of vengeance and transformation. They often see themselves as tragic figures forced into violence by a cruel world. Some explicitly reference pop culture, quoting films, invoking fictional characters, or modeling their identities after cinematic anti-heroes.
It would be reductive to claim Star Wars causes such events. But it is equally naive to believe that such narratives play no role in shaping the symbolic frameworks through which vulnerable individuals understand their lives. The story of Anakin Skywalker offers a dangerous script:
- You are betrayed.
- You suffer.
- You kill.
- You become powerful.
- You are redeemed.
When combined with militarized masculinity, institutional failure, and cultural nihilism, this script can validate the darkest impulses. It becomes a myth of sacrificial violence, with the perpetrator as misunderstood hero.
Part VI: Cultural Responsibility and Narrative Ethics
The problem is not that Star Wars tells a tragic story. Tragedy is essential to moral understanding. The problem is how the culture treats that story. Darth Vader is not treated as a warning, a cautionary tale, or a fallen angel. He is merchandised, celebrated, and decontextualized.
By separating his image from his actions, society rebrands him as a figure of cool dominance rather than ethical failure. The younglings are forgotten. The victims vanish. Only the redemption remains. The merchandise continues to sell.
Cultural institutions bear responsibility for how such narratives are presented and consumed. Filmmakers may intend nuance, but marketing departments, military institutions, and fan cultures often reduce that nuance to symbol and slogan.
Conclusion: Reckoning with the Stories We Tell
The story of Anakin Skywalker is not morally neutral. It is a tale of systemic failure, emotional collapse, and unchecked violence. When presented in full, it can serve as a powerful warning. But when reduced to aesthetic dominance and easy redemption, it becomes a tool of moral decay.
The glorification of Darth Vader as a cultural icon—divorced from the horrific acts that define his transformation—is not just misguided. It is dangerous. It trains a generation to believe that power erases guilt, that violence is a path to recognition, and that final acts of loyalty can overwrite the deliberate murder of the innocent.
To the uninitiated, Star Wars may seem like harmless fantasy. But its deepest myth—the redemption of the child-killer through familial love and posthumous honor—deserves scrutiny. Not because fiction causes violence, but because fiction defines the possibilities of how we understand evil, forgiveness, and what it means to be a hero.
We must ask: What kind of redemption erases the cries of murdered children? And what kind of culture finds peace in that forgetting?

2025-05-20 13:45:12LNbits now has full NWC support thanks to the work of contributor @riccardobl, who has claimed two LNbits bounties for implementing Nostr Wallet Connect (NWC) support in LNbits.
LNbits can now act both as a wallet service and as a funding source using the Nostr NWC protocol (NIP-47). This opens the door to new integrations with a growing ecosystem of Nostr clients and Lightning wallets.
Two Sides of NWC Integration
The work delivered by Riccardo B comprises two separate peices of work that together implement full support for NWC:
1. LNbits as a Wallet Service
This extension allows LNbits to operate as an always-on wallet service compatible with Nostr Wallet Connect clients such as Damus, Amethyst, or any app supporting NIP-47. Users can connect these Nostr clients to their LNbits instance and create and pay Lightning invoices through it.
This turns your LNbits wallet into a backend Lightning provider for your favourite Nostr app all self-hosted.
2. NWC as a Funding Source
The second piece of work flips the relationship. With this in place, LNbits can now act as an NWC client, meaning it can be funded from any NWC wallet service. This could be another LNbits, Alby, Minibits and more.
Why This Is a Big Deal for LNbits Users
These two bounties make LNbits one of the first applications in the Lightning ecosystem to offer bidirectional NWC support — as both a service and a client. This brings benefits such as:
-
Fund any NWC-compatible app using your LNbits wallet.
-
Fund LNbits using any wallet that supports Nostr Wallet Connect.
-
Build NWC-native apps with LNbits as a backend, or power your own LNbits server using existing wallet infrastructure.
For developers, it’s a chance to build in flexible, interoperable ways. For users, it means more choice, more control, and less friction when managing Lightning payments across apps and devices.
Both of these features were developed and delivered by Riccardo B (@riccardobl), an contributor who took on and completed both LNbits bounties and was extremely helpful during the PR review process. We owe a huge thanks to Riccardo for his work here.
To try them out, read the full article detailing how NWC works with LNbits.

2025-01-29 05:55:02The land that belongs to the indigenous peoples of Russia has been seized by a gang of killers who have unleashed a war of extermination. They wipe out anyone who refuses to conform to their rules. Those who disagree and stay behind are tortured and killed in prisons and labor camps. Those who flee lose their homeland, dissolve into foreign cultures, and fade away. And those who stand up to protect their people are attacked by the misled and deceived. The deceived die for the unchecked greed of a single dictator—thousands from both sides, people who just wanted to live, raise their kids, and build a future.
Now, they are forced to make an impossible choice: abandon their homeland or die. Some perish on the battlefield, others lose themselves in exile, stripped of their identity, scattered in a world that isn’t theirs.
There’s been endless debate about how to fix this, how to clear the field of the weeds that choke out every new sprout, every attempt at change. But the real problem? We can’t play by their rules. We can’t speak their language or use their weapons. We stand for humanity, and no matter how righteous our cause, we will not multiply suffering. Victory doesn’t come from matching the enemy—it comes from staying ahead, from using tools they haven’t mastered yet. That’s how wars are won.
Our only resource is the will of the people to rewrite the order of things. Historian Timothy Snyder once said that a nation cannot exist without a city. A city is where the most active part of a nation thrives. But the cities are occupied. The streets are watched. Gatherings are impossible. They control the money. They control the mail. They control the media. And any dissent is crushed before it can take root.
So I started asking myself: How do we stop this fragmentation? How do we create a space where people can rebuild their connections when they’re ready? How do we build a self-sustaining network, where everyone contributes and benefits proportionally, while keeping their freedom to leave intact? And more importantly—how do we make it spread, even in occupied territory?
In 2009, something historic happened: the internet got its own money. Thanks to Satoshi Nakamoto, the world took a massive leap forward. Bitcoin and decentralized ledgers shattered the idea that money must be controlled by the state. Now, to move or store value, all you need is an address and a key. A tiny string of text, easy to carry, impossible to seize.
That was the year money broke free. The state lost its grip. Its biggest weapon—physical currency—became irrelevant. Money became purely digital.
The internet was already a sanctuary for information, a place where people could connect and organize. But with Bitcoin, it evolved. Now, value itself could flow freely, beyond the reach of authorities.
Think about it: when seedlings are grown in controlled environments before being planted outside, they get stronger, survive longer, and bear fruit faster. That’s how we handle crops in harsh climates—nurture them until they’re ready for the wild.
Now, picture the internet as that controlled environment for ideas. Bitcoin? It’s the fertile soil that lets them grow. A testing ground for new models of interaction, where concepts can take root before they move into the real world. If nation-states are a battlefield, locked in a brutal war for territory, the internet is boundless. It can absorb any number of ideas, any number of people, and it doesn’t run out of space.
But for this ecosystem to thrive, people need safe ways to communicate, to share ideas, to build something real—without surveillance, without censorship, without the constant fear of being erased.
This is where Nostr comes in.
Nostr—"Notes and Other Stuff Transmitted by Relays"—is more than just a messaging protocol. It’s a new kind of city. One that no dictator can seize, no corporation can own, no government can shut down.
It’s built on decentralization, encryption, and individual control. Messages don’t pass through central servers—they are relayed through independent nodes, and users choose which ones to trust. There’s no master switch to shut it all down. Every person owns their identity, their data, their connections. And no one—no state, no tech giant, no algorithm—can silence them.
In a world where cities fall and governments fail, Nostr is a city that cannot be occupied. A place for ideas, for networks, for freedom. A city that grows stronger the more people build within it.

2025-05-20 15:51:33Introduction
It is becoming increasingly evident that sunlight is an essential nutrient for the body. To be more precise, the various wavelengths coming from the sun provide different benefits to the body, and each play a vital role in human health. Even more so, they work in concert with one another, as one wavelength may help reduce the potentially harmful effects of another. Benefits are maximized and harm reduced when we are exposed to the full breadth of this rainbow. This article will attempt to shed light on these various benefits and synergies.
To put this discussion into context, it is important to consider the overall health benefits of sunlight exposure. In a Swedish study that followed 29,000 women over 20 years, it was found that the mortality rate was doubled in those who avoided sun exposure when compared to those that didn’t (Lindqvist et al. 2016). Women who avoided the sun were twice as likely to die, primarily from cardiovascular disease, and there was no difference between death from malignant melanoma between the two groups (Lindqvist et al. 2016).
To understand why sunlight is so beneficial to health, it is important to make clear the diverse range of wavelengths that come from the sun. We typically think of the sun as a provider of both visible light and warmth. However, the spectrum of light visible to the human eye is a narrow band of the wavelengths actually emitted by the sun.
As wavelengths become shorter, visible light becomes more blue. Beyond the visible spectrum on the blue end, we arrive at ultraviolet (UV) light. On the other end of the spectrum are the longer red wavelengths. Outside of the visible window on the red side is infrared (IR) light, which provides heat. For helpful context, consider how shorter wavelengths have a harder time penetrating our atmosphere. So, the skies of dawn and dusk are predominately filled with red and near-infrared (NIR) light, while the middle of the day contains more blue and UV light. The bulk of wavelengths from the sun throughout the day are on the NIR end. The entire spectrum of visible and non-visible light between UV and IR plays critical roles in human health, especially towards mitochondrial health and metabolism. To summarize these benefits and provide a general overview for the following article, the benefits are as follows:
- UV – aids in the production of vitamin D and melanin, but also causes DNA damage
- Vitamin D improves immune system function and can repair DNA damage
- Melanin stores electrons for use within mitochondria
- Blue – involved in our circadian rhythm as the absence of blue light triggers the production of melatonin, an important antioxidant.
- Near-infrared (NIR) – improves mitochondria function and energy production while also protecting us from the harms of blue and UV light.
Ultraviolet Light
Let’s begin with a discussion around the widely misunderstood light of UV. UV is often viewed as a dangerous form of light, given that it can cause DNA damage and lead to cancer. While true, this myopic point of view ignores the crucial benefits of UV light. UV light produces vitamin D, which counteracts the DNA damage caused by UV while providing many other benefits. Additionally, UV light triggers the production of melanin, which aids in mitochondrial function. Like all physiological processes in the body that are vital to survival, there is a release of POMC-derived endorphins when skin comes into contact with UV light (Fell et al. 2014). Any person likely reading this article can agree that sitting under the sun simply feels amazing. We are drawn to it in a deeply meaningful sense.
Vitamin D is one of the most important chemicals regarding health, and it is poorly named. The term ‘vitamin’ refers to a compound that is important for health but cannot be adequately made within the body and must be retrieved externally. Peoples of the Northern and Southern hemisphere who are exposed to less UV light during winter would, for example, historically retrieve their vitamin D from foods such as oily fish, seal blubber, whale blubber, and polar bear liver (Wacker and Holick 2013). In a similar way, vitamin D was given its name 100 years ago when it was found that cod-liver oil was capable of curing rickets, when it was found that the so-called vitamin could promote calcium deposition in bones (McCollum et al. 1922). It was only until much later, in 1981, when scientists discovered that human skin could also synthesize vitamin D (M. F. Holick 1981). A majority of human vitamin D is produced by the skin when exposed to UVB (280 – 315 nm), while a minor amount is gained through food (Prietl et al. 2013; Wacker and Holick 2013). Most cells and organs in the human body have vitamin D receptors and many organs also have the ability to produce it, this speaks to the incredibly important nature of this compound towards our health (Prietl et al. 2013; Wacker and Holick 2013). Vitamin D deficiency has been associated with various types of cancer, autoimmune disorders, type 1 diabetes mellitus, multiple sclerosis (MS), cardiovascular disease, and even schizophrenia (Michael F. Holick 2007; Wacker and Holick 2013). Multiple studies have also found that vitamin D deficiency increases all-cause mortality (Garland et al. 2014; Yang et al. 2011; Chowdhury et al. 2014).
Though the historical benefits to vitamin D were attributed mainly to bone health, it is far more important. Vitamin D plays a critical role in protecting against invasive pathogens, reducing autoimmunity, and maintaining overall health (Wimalawansa 2023). Regarding immunity, one way it does this is by causing a shift away from proinflammatory responses to one more centered around T cell activation (Prietl et al. 2013). Vitamin D has therefore been shown to benefit other disorders that are related to immunity, such as a study that found vitamin D supplementation during pregnancy reduced asthmatic symptoms in children (Litonjua et al. 2016). That being said, it is important to highlight how there is no substitution for natural sunlight as a means of getting vitamin D. Naturally produced vitamin D from the skin lasts 2-3 times longer in the body (Wacker and Holick 2013). This is one of many likely reasons why the natural avenue should always be preferred over the supplemental. A similar line of reasoning follows in methods of getting UV light, as natural sun exposure leads to a decrease of all-cause mortality while the use of artificial tanning beds has been shown to increase all-cause and cancer mortality (Yang et al. 2011). More on why this likely occurs later.
Beyond vitamin D’s benefits to the immune system, it is important to focus on the compound’s role in mitochondrial health. In a previous article I wrote titled “Sunlight and Health”, I delve deeper into the importance of mitochondria and the science of how they work. In simplicity, imagine how all life on earth centers around energy. The sun provides energy to the earth, and the plethora of life on earth harness and facilitate the flow of that energy. Plants and animals share a symbiotic relationship within this system. Plants, through photosynthesis, take in sunlight, CO2, and water and create a glucose precursor and oxygen. This occurs within the chloroplast of plant cells. Within human cells, we have mitochondria. Our mitochondria, in turn, take in oxygen and glucose and produce CO2, water, and energy for our bodies in the form of ATP. What the plant breathes out, we breathe in, and vice versa. Mitochondria are central to all animal life on earth, and the ATP produced is central to all physiologic function. If your mitochondria are unhealthy, you are unhealthy and will experience disease.
Vitamin D plays a role in mitochondrial health at a DNA level. Our cells have DNA, which we inherited from our mother and father. On top of that, the mitochondria within our cells have their own set of DNA (mtDNA). Our mitochondria come from our mother’s egg, and therefore our mtDNA always is inherited from our mother. UV light can cause damage to both our DNA and mtDNA (Birch-Machin, Russell, and Latimer 2013). This is what gives UV light the ability to cause cancer. Additionally, damage to the mtDNA within our mitochondria can lead to mitochondrial dysfunction. The more poorly our mitochondria function, the less energy we produce for our cells, and the less healthy our cells become. There is research being developed that suggests the role of vitamin D is to counterbalance this danger by regulating gene transcription and reducing mtDNA damage. A mouse study conducted in 2011, for example, found that different shapes of vitamin D reduce the development of tumors in mice following UV exposure (Dixon et al. 2011). It is not unlike nature to create a system of checks and balances, to ensure that the damaging effects of UV light are counterbalanced by a compound produced by the body when exposure to that same light.
While vitamin D may be important for mitochondrial health by protecting against mtDNA damage, melanin potentially plays a much larger role. Melanin is the pigment in our skin that make us darker. Not only is the diversity in skin tones across humans due to variations in melanin content, but a tan is also the creation of more melanin. To be more specific, the skin’s exposure to UVA (315-400nm) leads to the creation of melanin (Wicks et al. 2011). The most obvious benefit to the production of melanin, which most people could appreciate, is that the darker or tanner our skin is, the less damage we will receive from UV light. In this way, melanin shares a similar responsibility to vitamin D, where both are protecting the body against the very thing that forms them. Even more crucially however, melanin acts as a battery for the mitochondria.
During cellular respiration, where mitochondria turn oxygen and glucose into energy, electrons are stripped from the glucose for use. In other words, what our mitochondria really need are oxygen and electrons, and the glucose is simply a means to an end. If the mitochondria are the engine, then the electrons are the fuel (assuming you are still breathing). Due to its chemical structure, melanin is a natural reversible oxidation-reduction system (Figge 1939). In other words, it can both store and release electrons. Melanin is therefore a kind of battery, retrieving electrons from various sources, and storing them for future use in our mitochondria as a substitute for food. When stated this way, and considering how food is important because both fats and carbohydrates fuel the body by providing electrons to our mitochondria, one can imagine how vitally important melanin is. Melanin is central towards the availability of electrons for use in our body to produce the energy to live. Without adequate melanin, your mitochondria will starve for fuel and not provide your body with the energy it needs to thrive.
Blue Light
To contextualize the role blue light plays in human health, it is important to revisit an important byproduct of cellular respiration within mitochondria. When mitochondria turn electrons and oxygen into energy, there is a byproduct formed known as reactive oxygen species (ROS). ROS play important roles in the body, but in excess they can cause DNA damage and disrupt various cellular processes. For example, UV light causes cancer due to the ROS generated, and studies have found that blue light does the same in both the skin and eyes (Nakashima, Ohta, and Wolf 2017; Abdouh et al. 2024). This research suggests that excess blue light or blue light in isolation can damage the eyes and cause harm like UV light.
Blue and UV light are predominant during the middle of the day. Though both may cause oxidative stress on the body, the body simultaneously counteracts this damage through melatonin. Think of melatonin as the junk remover for mitochondria. Throughout the day mitochondria produce energy, and ROS is formed. During our nighttime sleep, melatonin plays an important role as an antioxidant and removes the excess ROS (Leon et al. 2004).
The relationship between blue light and melatonin is important. During the day, when blue light is present, our body suppresses the production of melatonin (West et al. 2011). When the sun sets and there is no longer a heavy presence of blue light, our body begins to produce melatonin for sleep. This is a central function for how our body gets tired at night and gets ready for sleep. This is also why artificial light at night, from our modern technology, is harmful to human health because it tricks the body into the continual suppression of melatonin production. Without proper melatonin production, our cells buildup too much ROS and this can cause mitochondrial dysfunction and other sleep related issues.
Beyond the importance of getting good sleep and producing melatonin to remove excess ROS from our cells, the existence of artificial light and excess blue light is problematic during the day as well. As stated previously, blue light causes ROS buildup in both the skin and eyes (Nakashima, Ohta, and Wolf 2017; Abdouh et al. 2024). As with most harms from sunlight, our body has adapted with a backup plan. During the day, when blue and UV light is present, there is simultaneous exposure to NIR light (650-1200nm). Recent research suggests that NIR also counterbalances the harm of blue light by increasing melatonin synthesis in the mitochondria (Tan et al. 2023). This highlights the importance of receiving the full spectrum of light from the sun, as one wavelength counterbalances the damages of the other.
Near-Infrared Light
While indoor living has been commonplace for humans across generations, and modern technology has over saturated our bodies with blue light, some recent changes to our technology have made things worse. Incandescent light bulbs emit NIR light, this is why they got warm. However, LED lights do not emit NIR light. Therefore, where people of past generations were potentially exposed to a lot of artificial light at night, this was counterbalanced by the NIR emitted by those same lightbulbs. Now, modern humans use LEDs and spend 93% of our time indoors with zero exposure to NIR, which is 90% of the light emitted by the sun (Tan et al. 2023).
Not only does NIR light protect our bodies from the damaging consequences of blue light, but it similarly protects us against UV light. As stated previously, NIR may result in the production of melatonin within mitochondria during the day, helping protect against the ROS buildup and mtDNA damage. Additionally, research has also found that NIR light protects from UV light in other ways. For example, a study in 2008 found that pretreating skin with NIR light (660nm) prevented sunburns (Barolet and Boucher 2008). Another study found that red and NIR light (620-690nm) altered gene expression and upregulated DNA repair (Kim et al. 2019). Again, this highlights the theme that the body has produced the means to protect itself from the harms of the sun via other rays emitted. However, the protection from harmful rays is best achieved when exposed to the full spectrum of light wavelengths as they change throughout the day. The light of dawn and dusk is predominately red and NIR. Therefore, this research suggests that being exposed to morning light will protect the body from the potentially cancer-causing effects of the UV light later in the day. A human being who lived outside would naturally be exposed to this spectrum of light every day. However, modern humans may be inside in the morning, go to the beach during the middle of the day, and get sunburned because they do not properly receive the full spectrum of light as nature intended every day.
Lastly, it is important to explore the ways NIR improves mitochondrial function. If electrons are the fuel source for this engine, and melatonin is the junk removal, then NIR is the lubricant. NIR improves the energy output of mitochondria, and there are various hypotheses for how this occurs. One hypothesis is that NIR boosts the functionality of cytochrome c oxidase, one of the chromophores used in the electron transport chain (ETC) of cellular respiration within mitochondria (De Freitas and Hamblin 2016). Another involves NIR light’s ability to modify the viscosity of water which increases the efficiency of the final step in the ETC, the ATP synthase (Sommer, Haddad, and Fecht 2015). ATP synthase can be thought of as a kind of pump that produces ATP, in this way NIR can be thought of almost literally as a lubricant for this pump.
Summary
In summary, the research involving how sunlight affects mitochondrial health highlights the importance of the full spectrum of wavelengths, each of which plays a vital role in human health throughout the day. Having exposure to one, without the other, can lead to imbalances and mitochondrial disease. The red and NIR light in the morning helps our mitochondria produce more energy throughout the day, while also preparing our bodies for the beneficial yet dangerous wavelengths to come. In the middle of the day, we receive much more UV and blue light, which help us produce vitamin D and melanin, both central to health and wellness. Once the sun sets, and blue light is absent, we produce melatonin for sleep. During our sleep, the melatonin removes the dangerous byproducts of our energy-producing day, protecting us from disease and preparing us for the following day. Mitochondria are central to human health and life on earth, and the rays from the sun are central to mitochondrial health.
Respecting nature and its cycles is vital for us humans who are increasingly immersing ourselves in a world dominated by technology. Our ancestors did not have to reconcile with these ideas, because life forced these exposures upon them. If we wish to maintain health in our modern world, we must be able to find balance. Even though some might think they can escape into the virtual world, our bodies will always and forever be connected and reliant upon the natural one.

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

2025-01-26 15:26:44Secretary of State Marco Rubio issued new guidance halting spending on most foreign aid grants for 90 days, including military assistance to Ukraine. This immediate order shocked State Department officials and mandates “stop-work orders” on nearly all existing foreign assistance awards.
While it allows exceptions for military financing to Egypt and Israel, as well as emergency food assistance, it restricts aid to key allies like Ukraine, Jordan, and Taiwan. The guidance raises potential liability risks for the government due to unfulfilled contracts.
A report will be prepared within 85 days to recommend which programs to continue or discontinue.

2025-05-20 13:44:39Currently, and for the last three weeks, I am in Belfast. With the situation in HK becoming ever more crazy by the day we took the opportunity to escape from Hong Kong for a bit - I escaped with V and 3 suitcases. I also have some family matters that I am giving priority to at this time. We plan to stay a few more weeks in Northern Ireland and then after some time in Belgium we will be visiting some other European locations. I do hope that HK will be a place that we can go back to - we will see...
What's happening?
Quite a few significant events have happened in the last few weeks that deserve some deeper analysis and checking than you will ever get from the media propaganda circus that is running full force at the moment. You should be in no doubt that the "Great Reset" with its supporting "Great Narrative" is in full swing.
In most of the world the C19 story has run its course - for now. Most countries seem to have have "declared victory" and "moved on". Obviously HK is an exception (nothing happened there for the last two years) and I fear they will get to experience the whole 2-year thing in the coming 3-4 months. Watch out - the politicians everywhere are looking to permanently establish the "emergency controls" as "normal" - see previous Letter for some examples in Ireland and EU.
Invasion of Ukraine has led to so many lines being crossed - to the extent that clearly things will never be the same again in our lifetime.
Why? How did we get here?
I do not claim to know all the answers but some things are fairly clear if you look with open eyes and the wisdom that previous generations and civilisations have made available to us - even if most choose to ignore it (Plato on the flaws of democracy). Those who do not learn from history are doomed to repeat it and even those who learn will have litle choice but to go along for much of the ride.
Perhaps my notes and the links below will help you to form an educated opinion rather than the pervasive propaganda we are all being fed.
The current situation is more than 100 years in the making and much (if not most) of what you thought was true is less veracious than you could ever imagine. No doubt we could (and maybe should) go back further but let's start in 1913 when the British Government asked the public no longer to request exchange of their pounds for gold coins at the post office. This led to the issuing of War Bonds and fractional reserve accounting that allowed the Bank of England essentially to print unlimited money to fight in WW1; without this devious action they would have been constrained to act within the limits of the country's reserves and WW1 would have been shorter. Read The Fiat Standard for more details on how this happened. Around this time, and likely no coincidence, the US bankers were scheming how to get around the constitutional controls against such actions in their own country - read more in The Creature from Jekyll Island.
Following WW1, Germany was forced to pay war reparations in Gold (hard money). This led to a decade of money printing and extravagant excesses and crashes as hyperinflation set in, ending in the bankrupting of the country and the nationalism that fed WW2 - the gory details of devaluation and hyperinflation in Weimar Germany are described in When Money Dies. Meanwhile the US bankers who had been preparing since 1913 stepped in with unlimited money printing to fund WW2 and then also in their Marshal Plan to cement in place the Bretton Woods post-war agreement that made US Dollar the global reserve currency.
Decades of boom and bust followed - well explained by Ray Dalio who portrays this as perfectly normal and to be expected - unfortunately it is for soft (non-hard) money based economies. The Fourth Turning will give many additional insights to this period too as well as cycles to watch for and their cause and nature. In 1961 Eisenhower tried to warn the population in his farewell address about the "Military Industrial Complex" and many believe that Robert Kennedy's assassination in 1963 may well be not entirely unrelated.
Things came to a head in August 1971 when the countries of the world realised that the US was (contrary to all promises) printing unlimited funds to (among other things) fight the Vietnam war and so undermining the expected and required convertibility of US dollars (the currency of global trade) for Gold (hard money). A French warship heading to NY to collect France's gold was the straw that caused Nixon to default on US Debt convertibility and "close the gold window".
This in turn led to further decades of increasing financialization, further fuelled (pun intended) by the PetroDollar creation and "exorbitant priviledge" that the US obtained by having the global reserve currency - benefiting those closest to the money supply (Cantillon effect) while hollowing out the US manufacturing and eventually devastating its middle and working classes (Triffin dilemma) - Arthur Hayes describes all this and much more as well as the likely outlook in his article - Energy Canceled. Absolutely required reading or listen to Guy Swan reading it and giving his additional interpetation.
Zoltan Pozsar of Credit Suisse explains how the money system is now being reset following the events of last few weeks and his article outlines a likely way forward - Bretton Woods III. His paper is somewhat dense, heavy reading and you might prefer to listen to Luc Gromen's more conversational explainer with Marty
All of this was well known to our forefathers
The writers of the American Constitution understood the dangers of money being controlled by any elite group and they did their best to include protections in the US constitution. It did take the bankers multiple decades and puppet presidents to circumvent these but do so they did. Thomas Jefferson could not have been more clear in his warning.
" If the American people ever allow private banks to control the issue of their currency, first by inflation, then by deflation, the banks and corporations that will grow up around(these banks) will deprive the people of all property until their children wake up homeless on the continent their fathers conquered."
Islamic finace also recognised the dangers - you will likely be aware of the restrictions that forbid interest payments - read this interesting article from The Guardian
You will likely also be aware from schooldays that the Roman Empire collapsed because it expanded too much and the overhead became unbearable leading to the debasement of its money and inability to extract tax payments to support itself. Read more from Mises Institute. Here too, much of this will likely ring familiar.
So what can you do about it?
In theory Governments should respect Consent of the Governed and the 1948 Universal Declaration of Human Rights states that "The will of the people shall be the basis of the authority of government".
For you to decide if and to what extent governments today are acting in line with these principles. If not, what can you do about it?
The options you have are basically - Loyalty, Voice or Exit. 1. You can be loyal and accept what you are told - 2. you may (or may not) be able to voice disagreement and 3. you may (or may not!) be able to exit. Authoritarian governments will make everything except Loyalty difficult or even impossible - if in doubt, read George Orwell 1984 - or look just around at recent events today in many countries.
I'll be happy to delve deeper into this in subsequent letters if there is interest - for now I recommend you to read Sovereign Individual.

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.

2025-05-01 17:29:18High-Level Overview
Bitcoin developers are currently debating a proposed change to how Bitcoin Core handles the
OP_RETURN
opcode — a mechanism that allows users to insert small amounts of data into the blockchain. Specifically, the controversy revolves around removing built-in filters that limit how much data can be stored using this feature (currently capped at 80 bytes).Summary of Both Sides
Position A: Remove OP_RETURN Filters
Advocates: nostr:npub1ej493cmun8y9h3082spg5uvt63jgtewneve526g7e2urca2afrxqm3ndrm, nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg, nostr:npub17u5dneh8qjp43ecfxr6u5e9sjamsmxyuekrg2nlxrrk6nj9rsyrqywt4tp, others
Arguments: - Ineffectiveness of filters: Filters are easily bypassed and do not stop spam effectively. - Code simplification: Removing arbitrary limits reduces code complexity. - Permissionless innovation: Enables new use cases like cross-chain bridges and timestamping without protocol-level barriers. - Economic regulation: Fees should determine what data gets added to the blockchain, not protocol rules.
Position B: Keep OP_RETURN Filters
Advocates: nostr:npub1lh273a4wpkup00stw8dzqjvvrqrfdrv2v3v4t8pynuezlfe5vjnsnaa9nk, nostr:npub1s33sw6y2p8kpz2t8avz5feu2n6yvfr6swykrnm2frletd7spnt5qew252p, nostr:npub1wnlu28xrq9gv77dkevck6ws4euej4v568rlvn66gf2c428tdrptqq3n3wr, others
Arguments: - Historical intent: Satoshi included filters to keep Bitcoin focused on monetary transactions. - Resource protection: Helps prevent blockchain bloat and abuse from non-financial uses. - Network preservation: Protects the network from being overwhelmed by low-value or malicious data. - Social governance: Maintains conservative changes to ensure long-term robustness.
Strengths and Weaknesses
Strengths of Removing Filters
- Encourages decentralized innovation.
- Simplifies development and maintenance.
- Maintains ideological purity of a permissionless system.
Weaknesses of Removing Filters
- Opens the door to increased non-financial data and potential spam.
- May dilute Bitcoin’s core purpose as sound money.
- Risks short-term exploitation before economic filters adapt.
Strengths of Keeping Filters
- Preserves Bitcoin’s identity and original purpose.
- Provides a simple protective mechanism against abuse.
- Aligns with conservative development philosophy of Bitcoin Core.
Weaknesses of Keeping Filters
- Encourages central decision-making on allowed use cases.
- Leads to workarounds that may be less efficient or obscure.
- Discourages novel but legitimate applications.
Long-Term Consequences
If Filters Are Removed
- Positive: Potential boom in new applications, better interoperability, cleaner architecture.
- Negative: Risk of increased blockchain size, more bandwidth/storage costs, spam wars.
If Filters Are Retained
- Positive: Preserves monetary focus and operational discipline.
- Negative: Alienates developers seeking broader use cases, may ossify the protocol.
Conclusion
The debate highlights a core philosophical split in Bitcoin: whether it should remain a narrow monetary system or evolve into a broader data layer for decentralized applications. Both paths carry risks and tradeoffs. The outcome will shape not just Bitcoin's technical direction but its social contract and future role in the broader crypto ecosystem.

2025-01-21 01:51:46Bitcoin: Um sistema de dinheiro eletrônico direto entre pessoas.
Satoshi Nakamoto
satoshin@gmx.com
www.bitcoin.org
Resumo
O Bitcoin é uma forma de dinheiro digital que permite pagamentos diretos entre pessoas, sem a necessidade de um banco ou instituição financeira. Ele resolve um problema chamado gasto duplo, que ocorre quando alguém tenta gastar o mesmo dinheiro duas vezes. Para evitar isso, o Bitcoin usa uma rede descentralizada onde todos trabalham juntos para verificar e registrar as transações.
As transações são registradas em um livro público chamado blockchain, protegido por uma técnica chamada Prova de Trabalho. Essa técnica cria uma cadeia de registros que não pode ser alterada sem refazer todo o trabalho já feito. Essa cadeia é mantida pelos computadores que participam da rede, e a mais longa é considerada a verdadeira.
Enquanto a maior parte do poder computacional da rede for controlada por participantes honestos, o sistema continuará funcionando de forma segura. A rede é flexível, permitindo que qualquer pessoa entre ou saia a qualquer momento, sempre confiando na cadeia mais longa como prova do que aconteceu.
1. Introdução
Hoje, quase todos os pagamentos feitos pela internet dependem de bancos ou empresas como processadores de pagamento (cartões de crédito, por exemplo) para funcionar. Embora esse sistema seja útil, ele tem problemas importantes porque é baseado em confiança.
Primeiro, essas empresas podem reverter pagamentos, o que é útil em caso de erros, mas cria custos e incertezas. Isso faz com que pequenas transações, como pagar centavos por um serviço, se tornem inviáveis. Além disso, os comerciantes são obrigados a desconfiar dos clientes, pedindo informações extras e aceitando fraudes como algo inevitável.
Esses problemas não existem no dinheiro físico, como o papel-moeda, onde o pagamento é final e direto entre as partes. No entanto, não temos como enviar dinheiro físico pela internet sem depender de um intermediário confiável.
O que precisamos é de um sistema de pagamento eletrônico baseado em provas matemáticas, não em confiança. Esse sistema permitiria que qualquer pessoa enviasse dinheiro diretamente para outra, sem depender de bancos ou processadores de pagamento. Além disso, as transações seriam irreversíveis, protegendo vendedores contra fraudes, mas mantendo a possibilidade de soluções para disputas legítimas.
Neste documento, apresentamos o Bitcoin, que resolve o problema do gasto duplo usando uma rede descentralizada. Essa rede cria um registro público e protegido por cálculos matemáticos, que garante a ordem das transações. Enquanto a maior parte da rede for controlada por pessoas honestas, o sistema será seguro contra ataques.
2. Transações
Para entender como funciona o Bitcoin, é importante saber como as transações são realizadas. Imagine que você quer transferir uma "moeda digital" para outra pessoa. No sistema do Bitcoin, essa "moeda" é representada por uma sequência de registros que mostram quem é o atual dono. Para transferi-la, você adiciona um novo registro comprovando que agora ela pertence ao próximo dono. Esse registro é protegido por um tipo especial de assinatura digital.
O que é uma assinatura digital?
Uma assinatura digital é como uma senha secreta, mas muito mais segura. No Bitcoin, cada usuário tem duas chaves: uma "chave privada", que é secreta e serve para criar a assinatura, e uma "chave pública", que pode ser compartilhada com todos e é usada para verificar se a assinatura é válida. Quando você transfere uma moeda, usa sua chave privada para assinar a transação, provando que você é o dono. A próxima pessoa pode usar sua chave pública para confirmar isso.
Como funciona na prática?
Cada "moeda" no Bitcoin é, na verdade, uma cadeia de assinaturas digitais. Vamos imaginar o seguinte cenário:
- A moeda está com o Dono 0 (você). Para transferi-la ao Dono 1, você assina digitalmente a transação com sua chave privada. Essa assinatura inclui o código da transação anterior (chamado de "hash") e a chave pública do Dono 1.
- Quando o Dono 1 quiser transferir a moeda ao Dono 2, ele assinará a transação seguinte com sua própria chave privada, incluindo também o hash da transação anterior e a chave pública do Dono 2.
- Esse processo continua, formando uma "cadeia" de transações. Qualquer pessoa pode verificar essa cadeia para confirmar quem é o atual dono da moeda.
Resolvendo o problema do gasto duplo
Um grande desafio com moedas digitais é o "gasto duplo", que é quando uma mesma moeda é usada em mais de uma transação. Para evitar isso, muitos sistemas antigos dependiam de uma entidade central confiável, como uma casa da moeda, que verificava todas as transações. No entanto, isso criava um ponto único de falha e centralizava o controle do dinheiro.
O Bitcoin resolve esse problema de forma inovadora: ele usa uma rede descentralizada onde todos os participantes (os "nós") têm acesso a um registro completo de todas as transações. Cada nó verifica se as transações são válidas e se a moeda não foi gasta duas vezes. Quando a maioria dos nós concorda com a validade de uma transação, ela é registrada permanentemente na blockchain.
Por que isso é importante?
Essa solução elimina a necessidade de confiar em uma única entidade para gerenciar o dinheiro, permitindo que qualquer pessoa no mundo use o Bitcoin sem precisar de permissão de terceiros. Além disso, ela garante que o sistema seja seguro e resistente a fraudes.
3. Servidor Timestamp
Para assegurar que as transações sejam realizadas de forma segura e transparente, o sistema Bitcoin utiliza algo chamado de "servidor de registro de tempo" (timestamp). Esse servidor funciona como um registro público que organiza as transações em uma ordem específica.
Ele faz isso agrupando várias transações em blocos e criando um código único chamado "hash". Esse hash é como uma impressão digital que representa todo o conteúdo do bloco. O hash de cada bloco é amplamente divulgado, como se fosse publicado em um jornal ou em um fórum público.
Esse processo garante que cada bloco de transações tenha um registro de quando foi criado e que ele existia naquele momento. Além disso, cada novo bloco criado contém o hash do bloco anterior, formando uma cadeia contínua de blocos conectados — conhecida como blockchain.
Com isso, se alguém tentar alterar qualquer informação em um bloco anterior, o hash desse bloco mudará e não corresponderá ao hash armazenado no bloco seguinte. Essa característica torna a cadeia muito segura, pois qualquer tentativa de fraude seria imediatamente detectada.
O sistema de timestamps é essencial para provar a ordem cronológica das transações e garantir que cada uma delas seja única e autêntica. Dessa forma, ele reforça a segurança e a confiança na rede Bitcoin.
4. Prova-de-Trabalho
Para implementar o registro de tempo distribuído no sistema Bitcoin, utilizamos um mecanismo chamado prova-de-trabalho. Esse sistema é semelhante ao Hashcash, desenvolvido por Adam Back, e baseia-se na criação de um código único, o "hash", por meio de um processo computacionalmente exigente.
A prova-de-trabalho envolve encontrar um valor especial que, quando processado junto com as informações do bloco, gere um hash que comece com uma quantidade específica de zeros. Esse valor especial é chamado de "nonce". Encontrar o nonce correto exige um esforço significativo do computador, porque envolve tentativas repetidas até que a condição seja satisfeita.
Esse processo é importante porque torna extremamente difícil alterar qualquer informação registrada em um bloco. Se alguém tentar mudar algo em um bloco, seria necessário refazer o trabalho de computação não apenas para aquele bloco, mas também para todos os blocos que vêm depois dele. Isso garante a segurança e a imutabilidade da blockchain.
A prova-de-trabalho também resolve o problema de decidir qual cadeia de blocos é a válida quando há múltiplas cadeias competindo. A decisão é feita pela cadeia mais longa, pois ela representa o maior esforço computacional já realizado. Isso impede que qualquer indivíduo ou grupo controle a rede, desde que a maioria do poder de processamento seja mantida por participantes honestos.
Para garantir que o sistema permaneça eficiente e equilibrado, a dificuldade da prova-de-trabalho é ajustada automaticamente ao longo do tempo. Se novos blocos estiverem sendo gerados rapidamente, a dificuldade aumenta; se estiverem sendo gerados muito lentamente, a dificuldade diminui. Esse ajuste assegura que novos blocos sejam criados aproximadamente a cada 10 minutos, mantendo o sistema estável e funcional.
5. Rede
A rede Bitcoin é o coração do sistema e funciona de maneira distribuída, conectando vários participantes (ou nós) para garantir o registro e a validação das transações. Os passos para operar essa rede são:
-
Transmissão de Transações: Quando alguém realiza uma nova transação, ela é enviada para todos os nós da rede. Isso é feito para garantir que todos estejam cientes da operação e possam validá-la.
-
Coleta de Transações em Blocos: Cada nó agrupa as novas transações recebidas em um "bloco". Este bloco será preparado para ser adicionado à cadeia de blocos (a blockchain).
-
Prova-de-Trabalho: Os nós competem para resolver a prova-de-trabalho do bloco, utilizando poder computacional para encontrar um hash válido. Esse processo é como resolver um quebra-cabeça matemático difícil.
-
Envio do Bloco Resolvido: Quando um nó encontra a solução para o bloco (a prova-de-trabalho), ele compartilha esse bloco com todos os outros nós na rede.
-
Validação do Bloco: Cada nó verifica o bloco recebido para garantir que todas as transações nele contidas sejam válidas e que nenhuma moeda tenha sido gasta duas vezes. Apenas blocos válidos são aceitos.
-
Construção do Próximo Bloco: Os nós que aceitaram o bloco começam a trabalhar na criação do próximo bloco, utilizando o hash do bloco aceito como base (hash anterior). Isso mantém a continuidade da cadeia.
Resolução de Conflitos e Escolha da Cadeia Mais Longa
Os nós sempre priorizam a cadeia mais longa, pois ela representa o maior esforço computacional já realizado, garantindo maior segurança. Se dois blocos diferentes forem compartilhados simultaneamente, os nós trabalharão no primeiro bloco recebido, mas guardarão o outro como uma alternativa. Caso o segundo bloco eventualmente forme uma cadeia mais longa (ou seja, tenha mais blocos subsequentes), os nós mudarão para essa nova cadeia.
Tolerância a Falhas
A rede é robusta e pode lidar com mensagens que não chegam a todos os nós. Uma transação não precisa alcançar todos os nós de imediato; basta que chegue a um número suficiente deles para ser incluída em um bloco. Da mesma forma, se um nó não receber um bloco em tempo hábil, ele pode solicitá-lo ao perceber que está faltando quando o próximo bloco é recebido.
Esse mecanismo descentralizado permite que a rede Bitcoin funcione de maneira segura, confiável e resiliente, sem depender de uma autoridade central.
6. Incentivo
O incentivo é um dos pilares fundamentais que sustenta o funcionamento da rede Bitcoin, garantindo que os participantes (nós) continuem operando de forma honesta e contribuindo com recursos computacionais. Ele é estruturado em duas partes principais: a recompensa por mineração e as taxas de transação.
Recompensa por Mineração
Por convenção, o primeiro registro em cada bloco é uma transação especial que cria novas moedas e as atribui ao criador do bloco. Essa recompensa incentiva os mineradores a dedicarem poder computacional para apoiar a rede. Como não há uma autoridade central para emitir moedas, essa é a maneira pela qual novas moedas entram em circulação. Esse processo pode ser comparado ao trabalho de garimpeiros, que utilizam recursos para colocar mais ouro em circulação. No caso do Bitcoin, o "recurso" consiste no tempo de CPU e na energia elétrica consumida para resolver a prova-de-trabalho.
Taxas de Transação
Além da recompensa por mineração, os mineradores também podem ser incentivados pelas taxas de transação. Se uma transação utiliza menos valor de saída do que o valor de entrada, a diferença é tratada como uma taxa, que é adicionada à recompensa do bloco contendo essa transação. Com o passar do tempo e à medida que o número de moedas em circulação atinge o limite predeterminado, essas taxas de transação se tornam a principal fonte de incentivo, substituindo gradualmente a emissão de novas moedas. Isso permite que o sistema opere sem inflação, uma vez que o número total de moedas permanece fixo.
Incentivo à Honestidade
O design do incentivo também busca garantir que os participantes da rede mantenham um comportamento honesto. Para um atacante que consiga reunir mais poder computacional do que o restante da rede, ele enfrentaria duas escolhas:
- Usar esse poder para fraudar o sistema, como reverter transações e roubar pagamentos.
- Seguir as regras do sistema, criando novos blocos e recebendo recompensas legítimas.
A lógica econômica favorece a segunda opção, pois um comportamento desonesto prejudicaria a confiança no sistema, diminuindo o valor de todas as moedas, incluindo aquelas que o próprio atacante possui. Jogar dentro das regras não apenas maximiza o retorno financeiro, mas também preserva a validade e a integridade do sistema.
Esse mecanismo garante que os incentivos econômicos estejam alinhados com o objetivo de manter a rede segura, descentralizada e funcional ao longo do tempo.
7. Recuperação do Espaço em Disco
Depois que uma moeda passa a estar protegida por muitos blocos na cadeia, as informações sobre as transações antigas que a geraram podem ser descartadas para economizar espaço em disco. Para que isso seja possível sem comprometer a segurança, as transações são organizadas em uma estrutura chamada "árvore de Merkle". Essa árvore funciona como um resumo das transações: em vez de armazenar todas elas, guarda apenas um "hash raiz", que é como uma assinatura compacta que representa todo o grupo de transações.
Os blocos antigos podem, então, ser simplificados, removendo as partes desnecessárias dessa árvore. Apenas a raiz do hash precisa ser mantida no cabeçalho do bloco, garantindo que a integridade dos dados seja preservada, mesmo que detalhes específicos sejam descartados.
Para exemplificar: imagine que você tenha vários recibos de compra. Em vez de guardar todos os recibos, você cria um documento e lista apenas o valor total de cada um. Mesmo que os recibos originais sejam descartados, ainda é possível verificar a soma com base nos valores armazenados.
Além disso, o espaço ocupado pelos blocos em si é muito pequeno. Cada bloco sem transações ocupa apenas cerca de 80 bytes. Isso significa que, mesmo com blocos sendo gerados a cada 10 minutos, o crescimento anual em espaço necessário é insignificante: apenas 4,2 MB por ano. Com a capacidade de armazenamento dos computadores crescendo a cada ano, esse espaço continuará sendo trivial, garantindo que a rede possa operar de forma eficiente sem problemas de armazenamento, mesmo a longo prazo.
8. Verificação de Pagamento Simplificada
É possível confirmar pagamentos sem a necessidade de operar um nó completo da rede. Para isso, o usuário precisa apenas de uma cópia dos cabeçalhos dos blocos da cadeia mais longa (ou seja, a cadeia com maior esforço de trabalho acumulado). Ele pode verificar a validade de uma transação ao consultar os nós da rede até obter a confirmação de que tem a cadeia mais longa. Para isso, utiliza-se o ramo Merkle, que conecta a transação ao bloco em que ela foi registrada.
Entretanto, o método simplificado possui limitações: ele não pode confirmar uma transação isoladamente, mas sim assegurar que ela ocupa um lugar específico na cadeia mais longa. Dessa forma, se um nó da rede aprova a transação, os blocos subsequentes reforçam essa aceitação.
A verificação simplificada é confiável enquanto a maioria dos nós da rede for honesta. Contudo, ela se torna vulnerável caso a rede seja dominada por um invasor. Nesse cenário, um atacante poderia fabricar transações fraudulentas que enganariam o usuário temporariamente até que o invasor obtivesse controle completo da rede.
Uma estratégia para mitigar esse risco é configurar alertas nos softwares de nós completos. Esses alertas identificam blocos inválidos, sugerindo ao usuário baixar o bloco completo para confirmar qualquer inconsistência. Para maior segurança, empresas que realizam pagamentos frequentes podem preferir operar seus próprios nós, reduzindo riscos e permitindo uma verificação mais direta e confiável.
9. Combinando e Dividindo Valor
No sistema Bitcoin, cada unidade de valor é tratada como uma "moeda" individual, mas gerenciar cada centavo como uma transação separada seria impraticável. Para resolver isso, o Bitcoin permite que valores sejam combinados ou divididos em transações, facilitando pagamentos de qualquer valor.
Entradas e Saídas
Cada transação no Bitcoin é composta por:
- Entradas: Representam os valores recebidos em transações anteriores.
- Saídas: Correspondem aos valores enviados, divididos entre os destinatários e, eventualmente, o troco para o remetente.
Normalmente, uma transação contém:
- Uma única entrada com valor suficiente para cobrir o pagamento.
- Ou várias entradas combinadas para atingir o valor necessário.
O valor total das saídas nunca excede o das entradas, e a diferença (se houver) pode ser retornada ao remetente como troco.
Exemplo Prático
Imagine que você tem duas entradas:
- 0,03 BTC
- 0,07 BTC
Se deseja enviar 0,08 BTC para alguém, a transação terá:
- Entrada: As duas entradas combinadas (0,03 + 0,07 BTC = 0,10 BTC).
- Saídas: Uma para o destinatário (0,08 BTC) e outra como troco para você (0,02 BTC).
Essa flexibilidade permite que o sistema funcione sem precisar manipular cada unidade mínima individualmente.
Difusão e Simplificação
A difusão de transações, onde uma depende de várias anteriores e assim por diante, não representa um problema. Não é necessário armazenar ou verificar o histórico completo de uma transação para utilizá-la, já que o registro na blockchain garante sua integridade.
10. Privacidade
O modelo bancário tradicional oferece um certo nível de privacidade, limitando o acesso às informações financeiras apenas às partes envolvidas e a um terceiro confiável (como bancos ou instituições financeiras). No entanto, o Bitcoin opera de forma diferente, pois todas as transações são publicamente registradas na blockchain. Apesar disso, a privacidade pode ser mantida utilizando chaves públicas anônimas, que desvinculam diretamente as transações das identidades das partes envolvidas.
Fluxo de Informação
- No modelo tradicional, as transações passam por um terceiro confiável que conhece tanto o remetente quanto o destinatário.
- No Bitcoin, as transações são anunciadas publicamente, mas sem revelar diretamente as identidades das partes. Isso é comparável a dados divulgados por bolsas de valores, onde informações como o tempo e o tamanho das negociações (a "fita") são públicas, mas as identidades das partes não.
Protegendo a Privacidade
Para aumentar a privacidade no Bitcoin, são adotadas as seguintes práticas:
- Chaves Públicas Anônimas: Cada transação utiliza um par de chaves diferentes, dificultando a associação com um proprietário único.
- Prevenção de Ligação: Ao usar chaves novas para cada transação, reduz-se a possibilidade de links evidentes entre múltiplas transações realizadas pelo mesmo usuário.
Riscos de Ligação
Embora a privacidade seja fortalecida, alguns riscos permanecem:
- Transações multi-entrada podem revelar que todas as entradas pertencem ao mesmo proprietário, caso sejam necessárias para somar o valor total.
- O proprietário da chave pode ser identificado indiretamente por transações anteriores que estejam conectadas.
11. Cálculos
Imagine que temos um sistema onde as pessoas (ou computadores) competem para adicionar informações novas (blocos) a um grande registro público (a cadeia de blocos ou blockchain). Este registro é como um livro contábil compartilhado, onde todos podem verificar o que está escrito.
Agora, vamos pensar em um cenário: um atacante quer enganar o sistema. Ele quer mudar informações já registradas para beneficiar a si mesmo, por exemplo, desfazendo um pagamento que já fez. Para isso, ele precisa criar uma versão alternativa do livro contábil (a cadeia de blocos dele) e convencer todos os outros participantes de que essa versão é a verdadeira.
Mas isso é extremamente difícil.
Como o Ataque Funciona
Quando um novo bloco é adicionado à cadeia, ele depende de cálculos complexos que levam tempo e esforço. Esses cálculos são como um grande quebra-cabeça que precisa ser resolvido.
- Os “bons jogadores” (nós honestos) estão sempre trabalhando juntos para resolver esses quebra-cabeças e adicionar novos blocos à cadeia verdadeira.
- O atacante, por outro lado, precisa resolver quebra-cabeças sozinho, tentando “alcançar” a cadeia honesta para que sua versão alternativa pareça válida.
Se a cadeia honesta já está vários blocos à frente, o atacante começa em desvantagem, e o sistema está projetado para que a dificuldade de alcançá-los aumente rapidamente.
A Corrida Entre Cadeias
Você pode imaginar isso como uma corrida. A cada bloco novo que os jogadores honestos adicionam à cadeia verdadeira, eles se distanciam mais do atacante. Para vencer, o atacante teria que resolver os quebra-cabeças mais rápido que todos os outros jogadores honestos juntos.
Suponha que:
- A rede honesta tem 80% do poder computacional (ou seja, resolve 8 de cada 10 quebra-cabeças).
- O atacante tem 20% do poder computacional (ou seja, resolve 2 de cada 10 quebra-cabeças).
Cada vez que a rede honesta adiciona um bloco, o atacante tem que "correr atrás" e resolver mais quebra-cabeças para alcançar.
Por Que o Ataque Fica Cada Vez Mais Improvável?
Vamos usar uma fórmula simples para mostrar como as chances de sucesso do atacante diminuem conforme ele precisa "alcançar" mais blocos:
P = (q/p)^z
- q é o poder computacional do atacante (20%, ou 0,2).
- p é o poder computacional da rede honesta (80%, ou 0,8).
- z é a diferença de blocos entre a cadeia honesta e a cadeia do atacante.
Se o atacante está 5 blocos atrás (z = 5):
P = (0,2 / 0,8)^5 = (0,25)^5 = 0,00098, (ou, 0,098%)
Isso significa que o atacante tem menos de 0,1% de chance de sucesso — ou seja, é muito improvável.
Se ele estiver 10 blocos atrás (z = 10):
P = (0,2 / 0,8)^10 = (0,25)^10 = 0,000000095, (ou, 0,0000095%).
Neste caso, as chances de sucesso são praticamente nulas.
Um Exemplo Simples
Se você jogar uma moeda, a chance de cair “cara” é de 50%. Mas se precisar de 10 caras seguidas, sua chance já é bem menor. Se precisar de 20 caras seguidas, é quase impossível.
No caso do Bitcoin, o atacante precisa de muito mais do que 20 caras seguidas. Ele precisa resolver quebra-cabeças extremamente difíceis e alcançar os jogadores honestos que estão sempre à frente. Isso faz com que o ataque seja inviável na prática.
Por Que Tudo Isso é Seguro?
- A probabilidade de sucesso do atacante diminui exponencialmente. Isso significa que, quanto mais tempo passa, menor é a chance de ele conseguir enganar o sistema.
- A cadeia verdadeira (honesta) está protegida pela força da rede. Cada novo bloco que os jogadores honestos adicionam à cadeia torna mais difícil para o atacante alcançar.
E Se o Atacante Tentar Continuar?
O atacante poderia continuar tentando indefinidamente, mas ele estaria gastando muito tempo e energia sem conseguir nada. Enquanto isso, os jogadores honestos estão sempre adicionando novos blocos, tornando o trabalho do atacante ainda mais inútil.
Assim, o sistema garante que a cadeia verdadeira seja extremamente segura e que ataques sejam, na prática, impossíveis de ter sucesso.
12. Conclusão
Propusemos um sistema de transações eletrônicas que elimina a necessidade de confiança, baseando-se em assinaturas digitais e em uma rede peer-to-peer que utiliza prova de trabalho. Isso resolve o problema do gasto duplo, criando um histórico público de transações imutável, desde que a maioria do poder computacional permaneça sob controle dos participantes honestos. A rede funciona de forma simples e descentralizada, com nós independentes que não precisam de identificação ou coordenação direta. Eles entram e saem livremente, aceitando a cadeia de prova de trabalho como registro do que ocorreu durante sua ausência. As decisões são tomadas por meio do poder de CPU, validando blocos legítimos, estendendo a cadeia e rejeitando os inválidos. Com este mecanismo de consenso, todas as regras e incentivos necessários para o funcionamento seguro e eficiente do sistema são garantidos.

2025-05-20 13:44:28I https://www.chrisliss.com/p/mstr a few months ago with the subtitle “The Only Stock,” and I’m starting to regret it. Now, it was trading at 396 on January 20 when I posted it and 404 now (even if it dipped 40 percent to 230 or so in between), but that’s not why I regret it. I pointed out it was not investable unless you’re willing to stomach large drawdowns, and anyone who bought then could exit with a small profit now had they not panic-sold along the way.
The reason I regret it is I don’t want to make public stock predictions because it adds stress to my life. I have not sold any of my shares yet, but something I’ve noticed recently has got me thinking about it, and stock tips are like a game of telephone wherein whoever is last in the chain might find out the wrong information and too late. And while every adult has agency and is responsible for his own financial decisions, I don’t want my readers losing money on account of anything I write.
My base case is still that MSTR becomes a trillion-dollar company, destroys the performance of the S&P, the Mag-7 and virtually any other equity portfolio most people would assemble. Michael Saylor is trading an infinitely-printable asset (his shares) for humanity’s best-ever, finite-supply digital gold, and that trade should be profitable for him and his shareholders in perpetuity.
I don’t know exactly what he plans to do when that trade is no longer available to him — either because no one takes fiat currency for bitcoin anymore or because his mNAV (market-cap-to-bitcoin-holding ratio) goes below one — but that’s not my main concern, either. At that point he’ll have so much bitcoin, he’ll probably become the world’s first and largest bitcoin bank and profit by making his pristine collateral available to individuals and institutions. Even at five percent interest, half a trillion in bitcoin would yield $25B in profits every year. Even at a modest 10x valuation, the stock would more than double from here.
I am also not overly concerned with Saylor’s present amount of convertible debt which is at low or zero rates and is only https://www.strategy.com/. He’s been conservative on that front and only issuing on favorable terms. I don’t doubt Saylor’s prescience, intelligence or business sense one bit.
What got me thinking were some Twitter posts by a former Salomon Brothers trader/prophet Josh Mandell https://x.com/JoshMandell6/status/1921597739458339193 recently. In November when bitcoin was mooning after the election, he predicted that on March 14th it would close at $84,000, and if it did it would then go on an epic run up to $444,000 this cycle.
A lot of people make predictions, a few of them come true, but rarely do they come true on the dot (it closed at exactly $84K according to some exchanges) and on such a specific timeframe. Now, maybe he just got lucky, or maybe he is a skilled trader who made one good prediction, but the reason he gave for his prediction, insofar as he gave one, was not some technical chart or quantitative analysis, but a memory he had from 30 years ago that got into his mind that he couldn’t shake. He didn’t get much more specific than that, other than that he was tuned into something that if he explained fully would make too many people think he had gone insane. And then the prediction came true on the dot months later.
Now I believe in the paranormal more than the average person. I do not think things are random, and insofar as they appear that way it’s only because we have incomplete information — even a coin toss is predictable if you knew the exact force and spin that was put on the coin. I think for whatever reason, this guy is plugged into something, and while I would never invest a substantial amount of money on that belief — not only are earnestly-made prophecies often delusions or even if correct wrongly interpreted — that he sold makes me think.
He gave more substantive reasons for selling than prophecy, by the way — he seems to think Saylor’s perpetual issuance of shares ATM (at the market) to buy more bitcoin is putting too much downward pressure on the stock. Obviously, selling shares — even if to buy the world’s most pristine collateral at a 2x-plus mNAV — reduces the short-term appreciation of those shares.
His thesis seems to be that Saylor is doing this even if he would be better off letting the price appreciate more, attracting more investors, squeezing more shorts, etc because he needs to improve his credit rating to tap into the convertible debt market to the extent he has promised ($42 billion more over the next few years) at favorable terms. But in doing this, he is souring common stock investors because they are not seeing the near-term appreciation they should on their holdings.
Now this is a trivial concern if over the long haul MSTR does what it has the last couple years which is to outperform by a wide margin not only every large cap stock and the S&P but bitcoin itself. And the bigger his stack of bitcoin, the more his stock should appreciate as bitcoin goes up. But markets do not operate linearly and rationally. Should he sour prospective buyers to a great enough extent, should he attract shorts (and supply them with available shares to borrow) to a great enough extent, perhaps there might be an mNAV-crushing cascade that drives people into other bitcoin treasury companies, ETFs or bitcoin itself.
Now Saylor as first mover and by far the largest publicly-traded treasury company has a significant advantage. Institutions are far less likely to invest in size in smaller treasury companies with shorter track records, and many of them are not allowed to invest in ETFs or bitcoin at all. And even if a lot of money did go into any of those vehicles, it would only drive the value of his assets up and hence his stock price, no matter the mNAV. But Josh Mandell sold his shares prior to a weekend where bitcoin went from 102K to 104K, the US announced a deal with China, the mag-7 had a big spike (AAPL was up 6.3 percent) and then MSTR’s stock went down from 416 to 404. As I said, he is on to something.
So what’s the real long-term risk? I don’t know. Maybe there’s something about the nature of bitcoin that long-term is not really amenable to third-party custody and administration. It’s a bearer asset (“not your keys, not your coins”), and introducing counterparty risk is antithetical to its core purpose, the separation of money and state, or in this case money and bank.
With the bitcoin network you can literally “be your own bank.” To transact in digital dollars you need a bank account — or at least a stable coin one mediated by a centralized entity like Tether. You can’t hold digital dollars in your mind via some memorized seed words like you can bitcoin, accessible anywhere in the world, the ledger of which is maintained by tens of thousands of individually-run nodes. This property which democratizes value storage in the way gold did, except now you can wield your purchasing power globally, might be so antithetical to communal storage via corporation or bank that doing so is doomed to catastrophe.
We’ve already seen this happen with exchanges via FTX and Mt. Gox. Counterparty risk is one of the problems bitcoin was created to solve, so moving that risk from a fractionally reserved international banking system to corporate balance sheets still very much a part of that system is probably not the seismic advancement integral to the technology’s promise.
But this is more of a philosophical concern rather than a concrete one. To get more specific, it’s easy to imagine Coinbase, if indeed that’s where MSTR custodies its coins, gets hacked or https://www.chrisliss.com/p/soft-landing, i.e., seized by an increasingly desperate and insolvent government. Or maybe Coinbase simply doesn’t have the coins it purports like FTX, or a rogue band of employees, working on behalf of some powerful faction for “https://www.chrisliss.com/national-security-and-public-healt” executes the rug pull. Even if you deem these scenarios unlikely, they are not unfathomable.
Beyond outright counterparty malfeasance, there are other risks — what if owning common stock in an enterprise that simply holds bitcoin falls out of favor? Imagine if some new individual custody solution emerges wherein you have direct access to the coins themselves in an “even a boomer can do this” kind of way wherein there’s no compelling reason to own common stock with its junior claims to the capital stack in the event of insolvency? Why stand in line behind debt holders and preferred shares when you can invest in something that’s directly withdrawable and accessible if world events spike volatility to a systemic breaking point?
Things need not even get that rocky for this to be a concern — just the perception that they might could spook people into realizing common stock of a corporate balance sheet might be less than ideal as your custody solution.
Moreover, Saylor himself presents some risk. He could be compromised or blackmailed, he could lose his cool or get into an accident. These are low-probability scenarios, but also not unfathomable as any single point of failure is a target, especially for those factions who stand to lose unimaginable wealth and power should his speculative attack on the system succeed at scale.
Finally, even if Saylor remains free to operate as he sees fit, there is what I’d call the Icarus risk — he might be too ambitious, too hell-bent on acquiring bitcoin at all costs, too much of a maniac in service of his vision. Remember, he initially bought bitcoin during the covid crash and concomitant massive money print upon his prescient realization that businesses providing goods and services couldn’t possibly keep pace with inflation over the long haul. He was merely playing defense to preserve his capital, and now, despite his sizable lead and secured position is still throwing forward passes in the fourth quarter rather than running out the clock and securing the W.
Saylor is now arguably less a bitcoin maximalist and advocate, articulately making the case for superior money and individual sovereignty, but a corporate titan hell-bent on world domination via apex-predator-status balance sheet. When is enough enough? Many of the greatest conquerors in history pushed their empires too far until they fractured. In fact, 25 years ago MSTR was a big winner before the dot-com crash during which its stock price and most of Saylor’s fortune were wiped out when he was sued by the SEC for accounting fraud (he subsequently settled).
Now it’s possible, he learned from that experience, got up off the mat and figured out how to avoid his youthful mistakes. But it’s also possible his character is such that he will repeat it again, only this time at scale.
But as I said, my base case is MSTR is a trillion-dollar market cap, and the stock runs in parallel with bitcoin’s ascendance over the next decade. Saylor has been https://www.strategy.com/, prescient, bold and responsible so far over this iteration. I view Mandell’s concerns as valid, but similar to Wall St’s ones about AMZN’s Jeff Bezos who relentlessly ignored their insistence on profitability for a decade as he plowed every dollar into building out productive capacity and turned the company into the $2T world-dominating retail giant it is now.
Again, I haven’t (yet) sold any of my shares or even call options. But because I posted about this in January I felt I should at least follow-up with a more detailed rundown of what I take to be the risks. As always, do your own due diligence with any prospective investment.

2025-05-20 13:38:04When I was a kid, I wanted to be rich, but found the prospect of hard work tedious, pointless and soul-crushing. Instead of studying for exams, getting some job and clawing your way up the ladder, I wondered why we couldn’t just build a device that measured your brain capacity and awarded you the money you would have made had you applied yourself. Eliminate the middleman, so to speak, the useless paper pushing evoked by the word “career.”
But when you think about it, it’s not really money you’re after, as money is but purchasing power, and so it’s the things money can provide like a nice lifestyle and the peace of mind that comes from not worrying about it. And it’s not really the lifestyle or financial independence, per se, since moment to moment what’s in your bank account isn’t determining your mental state, but the feeling those things give you — a sense of expansiveness and freedom.
But if you did have such a machine, and it awarded you the money, you probably wouldn’t have that kind of expansiveness and freedom, especially if you did nothing to achieve those things. You would still feel bored, distracted and unsatisfied despite unrestricted means to travel or dine out as you saw fit. People who win the lottery, for example, tend to revert to their prior level of satisfaction in short order.
The feeling you really want then is the sense of rising to a challenge, negotiating and adapting to your environment, persevering in a state of uncertainty, tapping into your resourcefulness and creativity. It’s only while operating at the edge of your capacity you could ever be so fulfilled. In fact, in such a state the question of your satisfaction level would never come up. You wouldn’t even think to wonder about it you’d be so engrossed.
So what you really crave is a mind device that encourages you to adapt to your environment using your full creative capabilities in the present moment, so much so you realize if you do not do this, you have the sense of squandering your life in a tedious, pointless and soul-crushing way. You need to be totally stuck, without the option of turning back. In sum, you need to face reality exactly as it is, without any escape therefrom.
The measure of your mind in that case is your reality itself. The device is already with you — it’s the world you are presently creating with the consciousness you have, providing you avenues to escape, none of which are satisfactory, none that can lead to the state you truly desire. You have a choice to pursue them fruitlessly and wind up at square one, or to abandon them and attain your freedom. No matter how many times you go down a false road, you wind up at the same place until you give up on the Sisyphean task and proceed in earnest.
My childhood fantasy was real, it turns out, only I had misunderstood its meaning.

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.
