E-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. https://github.com/nostr-protocol/nips/blob/master/60.md

#intro 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.

My 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](https://www.youtube.com/shorts/kqsomjpz7ok): “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](https://youtu.be/ut8UqFlWdDc) 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.” *Libertas magnitudo est*

There 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](https://geek.npub.pro/post/dxqkgnjplttkvetprg8ox/), 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](https://lightning.network/) or [Cashu](https://cashu.space/) 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.

I got into a [friendly discussion](https://x.com/snoyberg/status/1887007888117252142) 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: 1. 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. 2. 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." https://x.com/i/grok/share/Zc8yOdrN8lS275hXJ92uwq98M

Novia é uma ferramenta inovadora que facilita o arquivamento de vídeos e sua integração com a rede NOSTR (Notes and Other Stuff Transmitted over Relay). Funcionando como uma ponte entre ferramentas de arquivamento de vídeo tradicionais e a plataforma descentralizada, Novia oferece uma solução autônoma para a preservação e compartilhamento de conteúdo audiovisual. ### Arquitetura e Funcionamento A arquitetura de Novia é dividida em duas partes principais: * **Frontend:** Atua como a interface do usuário, responsável por solicitar o arquivamento de vídeos. Essas solicitações são encaminhadas para o backend. * **Backend:** Processa as solicitações de arquivamento, baixando o vídeo, suas descrições e a imagem de capa associada. Este componente é conectado a um ou mais relays NOSTR, permitindo a indexação e descoberta do conteúdo arquivado. O processo de arquivamento é automatizado: após o download, o vídeo fica disponível no frontend para que o usuário possa solicitar o upload para um servidor Blossom de sua escolha. ### Como Utilizar Novia 1. **Acesso:** Navegue até [https://npub126uz2g6ft45qs0m0rnvtvtp7glcfd23pemrzz0wnt8r5vlhr9ufqnsmvg8.nsite.lol](https://npub126uz2g6ft45qs0m0rnvtvtp7glcfd23pemrzz0wnt8r5vlhr9ufqnsmvg8.nsite.lol). 2. **Login:** Utilize uma extensão de navegador compatível com NOSTR para autenticar-se. 3. **Execução via Docker:** A forma mais simples de executar o backend é através de um container Docker. Execute o seguinte comando: ```bash docker run -it --rm -p 9090:9090 -v ./nostr/data:/data --add-host=host.docker.internal:host-gateway teamnovia/novia ``` Este comando cria um container, mapeia a porta 9090 para o host e monta o diretório `./nostr/data` para persistir os dados. ### Configuração Avançada Novia oferece amplas opções de configuração através de um arquivo `yaml`. Abaixo, um exemplo comentado: ```yaml mediaStores: - id: media type: local path: /data/media watch: true database: /data/novia.db download: enabled: true ytdlpPath: yt-dlp ytdlpCookies: ./cookies.txt tempPath: /tmp targetStoreId: media secret: false publish: enabled: true key: nsec thumbnailUpload: - https://nostr.download videoUpload: - url: https://nostr.download maxUploadSizeMB: 300 cleanUpMaxAgeDays: 5 cleanUpKeepSizeUnderMB: 2 - url: https://files.v0l.io maxUploadSizeMB: 300 cleanUpMaxAgeDays: 5 cleanUpKeepSizeUnderMB: 2 - url: https://nosto.re maxUploadSizeMB: 300 cleanUpMaxAgeDays: 5 cleanUpKeepSizeUnderMB: 2 - url: https://blossom.primal.net maxUploadSizeMB: 300 cleanUpMaxAgeDays: 5 cleanUpKeepSizeUnderMB: 2 relays: - ws://host.docker.internal:4869 - wss://bostr.bitcointxoko.com secret: false autoUpload: enabled: true maxVideoSizeMB: 100 fetch: enabled: false fetchVideoLimitMB: 10 relays: - <a relay with the video events to mirror> match: - nostr - bitcoin server: port: 9090 enabled: true ``` **Explicação das Configurações:** * **`mediaStores`**: Define onde os arquivos de mídia serão armazenados (localmente, neste exemplo). * **`database`**: Especifica o local do banco de dados. * **`download`**: Controla as configurações de download de vídeos, incluindo o caminho para o `yt-dlp` e um arquivo de cookies para autenticação. * **`publish`**: Configura a publicação de vídeos e thumbnails no NOSTR, incluindo a chave privada (`nsec`), servidores de upload e relays. **Atenção:** Mantenha sua chave privada em segredo. * **`fetch`**: Permite buscar eventos de vídeo de relays NOSTR para arquivamento. * **`server`**: Define as configurações do servidor web interno de Novia. ### Conclusão Novia surge como uma ferramenta promissora para o arquivamento e a integração de vídeos com o ecossistema NOSTR. Sua arquitetura modular, combinada com opções de configuração flexíveis, a tornam uma solução poderosa para usuários que buscam preservar e compartilhar conteúdo audiovisual de forma descentralizada e resistente à censura. A utilização de Docker simplifica a implantação e o gerenciamento da ferramenta.

 Federal employees must remove pronouns from email signatures by the end of the day. This directive comes from internal memos tied to two executive orders signed by Donald Trump. The orders target diversity and equity programs within the government.  CDC, Department of Transportation, and Department of Energy employees were affected. Staff were instructed to make changes in line with revised policy prohibiting certain language. One CDC employee shared frustration, stating, “In my decade-plus years at CDC, I've never been told what I can and can't put in my email signature.” The directive is part of a broader effort to eliminate DEI initiatives from federal discourse.

I have a deep love of China. It probably started in 1981, when my Father visited China on the first trade mission from the UK to open up trading between the 2 nations. As a family, we have historically done a lot of business in Asia starting with our company Densitron, who’s Asian headquarters were in Tokyo, through to Taiwan where we had factories leading to investing in Vbest, now Evervision an LCD manufacturer. They have admin offices in Taiwan and a factory in Jiangsu, China. I have always hated the western narrative that China is the “enemy” or that China’s Communist / Capitalist system is “evil”. Without understanding history, geography, cultural biases, and indoctrination it is as difficult to remove those beliefs in the same way it is difficult to convert “normies” to understand the freedom and power of Bitcoin. I have tried and had some success, but mostly failed. However the recent ban on TikTok and the migration of the west to the Chinese owned “rednote” app has overnight created more cultural exchanges and understanding than the previous 40+ years has ever managed to achieve. That along with the recent disclosure about Chinas advancements in AI have also deflated some of the western hubris. If you wish to go down the rabbit hole of China from a cultural view, this YouTuber has given me a much better framework than I could ever provide as an outsider. She is a Chinese girl, who came to the UK to study at University only to return with a mixed understanding of both cultures. She is doing a far better job of explaining the culture from a western perspective than I ever could. https://www.youtube.com/@SimingLan Here are 4 videos of hers that help explain a lot: This is a lighthearted look at the recent TikTok ban TikTok ban completely backfired on US! and it's been hilarious https://www.youtube.com/watch?v=A7123nG5otA More in-depth insights are: My complicated relationship with China. https://www.youtube.com/watch?v=BEaw0KAuNBU China's Biggest Problem with Free Speech Rhetoric https://www.youtube.com/watch?v=V7eSyKPbg_Y What the West Doesn't Get about China's Rise https://www.youtube.com/watch?v=hmb1_HfflCA

**"Degeneration"** or **"Вырождение"** ![[photo_2025-01-29 23.23.15.jpeg]] 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.

Humanity as a whole has been degrading over the years, with average IQ decreasing, bone structures generally becoming poorly formed and fragile, average height decreasing, hormone levels ridiculously low and having various metabolic and mental illnesses becoming “normal”. “*By 2024, more than 800 million adults were living with diabetes, representing a more than fourfold increase since 1990*” “\*\**1 in 3 people suffer from insulin resistance and can cause depression*” (\*\*https://olhardigital.com.br/2021/09/24/medicina-e-saude/1-em-cada-3-pessoas-sofre-de-resistencia-a-insulina-e-pode-causar-depressao/) “*More than 1.3 billion people will have diabetes in the world by 2050*” (https://veja.abril.com.br/saude/mais-de-13-bilhao-de-pessoas-terao-diabetes-no-mundo-ate-2050) “*A new study released by Lancet, with data from 2022, shows that more than a billion people live with obesity in the world*” (https://www.paho.org/pt/noticias/1-3-2024-uma-em-cada-oito-pessoas-no-mundo-vive-com-obesidade) All this due to a single factor: diet. I’m not referring to a diet full of processed foods, as this has already been proven to destroy the health of those who eat it. I’m referring to the modern diet, with carbohydrates (from any source, even from fruit) being the main macronutrient, little animal protein and practically no saturated fat of animal origin. This diet implementation has been systematically occurring for decades. Sugar conglomerates seeking profits? Government institutions (after all, they need voters to be stupid and vote for them), evil spiritual interference wanting to destroy or distort their path? I don’t know, I’ll leave the conspiracy theories to you! The modern diet or diet is extremely inflammatory, and inflammation over a long period of time leads to autoimmune diseases such as diabetes and Hashimoto’s. Absolutely any food in the plant kingdom will harm you, no matter how asymptomatic it may be. Plants are living beings and do not want to die and be eaten. To defend themselves from this, they did not evolve legs like animals. They specifically developed chemical mechanisms such as *oxalates, phytoalexins, glucosinolates, polyphenols, antinutrients* and many others that act to repel anything that wants to eat them, being fatal (as in the case of mushrooms), causing discomfort and the animal or insect discovering that the plant is not edible, releasing unpleasant smells or, in many cases, a combination of these factors. Not to mention genetically modified foods (almost the entire plant kingdom is genetically modified) that work as a steroid for the plants' defenses. - Lack of focus - Poor decision-making - Difficulty in establishing and maintaining relationships - Difficulty getting pregnant and difficult pregnancy - Low testosterone (medical reference values ​​are low) - Alzheimer's - Diabetes - Dementia - Chances of developing autism when mothers do not eat meat and fat properly during pregnancy - Worsening of the degree of autism when the child does not eat meat and fat (food selectivity) - Insomnia and other sleep problems - Lack of energy - Poorly formed and fragile bone structure - Lack of willpower - Depression - ADHD Not having full physical and mental capacity harms you in many different ways, these are just a few examples that not only directly impact one person but everyone else around them. Fortunately, there is an alternative to break out of this cycle of destruction, ***Carnivore Diet***. I am not here to recommend a diet, eating plan or cure for your health problems, nor can I do so, as I am not a doctor (most doctors don't even know where the pancreas is, a mechanic is more useful in your life than a doctor, but that is a topic for another text.). I came to present you with logic and facts in a very simplified way, from there you can do your own research and decide what is best for you. --- ## Defining the carnivore diet Simply put, the carnivore diet is an elimination diet, where carbohydrates (including fruits), vegetable fats (soy, canola, cotton, peanuts, etc.), processed products and any type of plant, be it spices or teas, are completely removed. ### What is allowed on the carnivore diet? - Animal protein - Beef, preferably fatty cuts (including offal, liver, heart, kidneys, these cuts have more vitamins than anything else in the world) - Lamb - Eggs - Fish and seafood - Animal fat - Butter - Beef fat and tallow - Salt - No... salt does not cause high blood pressure. (explained later about salt and high consumption of saturated fats) From now on I will list some facts that disprove the false accusations made against \*\*eating exclusively meat and fat. # “Human beings are omnivores” *“Our ancestors were gatherers and hunters*" To determine the proportion of animal foods in our ancestors’ diets, we can look at the amount of δ15 nitrogen in their fossils. By looking at levels of this isotope, researchers can infer where animals reside in the food chain, identifying their protein sources. Herbivores typically have δ15N levels of 3–7 percent, carnivores show levels of 6–12 percent, and omnivores exhibit levels in between. When samples from Neanderthals and early modern humans were analyzed, they showed levels of 12 percent and 13.5 percent, respectively, even higher than those of other known carnivores, such as hyenas and wolves. And from an energy efficiency standpoint, hunting large animals makes the most sense. Gathering plants and chasing small animals provides far fewer calories and nutrients relative to the energy invested. In more recently studied indigenous peoples, we have observed a similar pattern that clearly indicates a preference for animal foods over plant foods. For example, in Vilhjalmur Stefansson’s studies of the Eskimos. *“…fat, not protein, seemed to play a very important role in hunters’ decisions about which animals (male or female) to kill and which body parts to discard or carry away.”* Why were our ancestors and more recent indigenous peoples so interested in finding fat? At a very basic level, it was probably about calories. By weight, fat provides more than twice as many calories as protein or carbohydrates. Furthermore, human metabolism makes fat an exceptionally valuable and necessary food. If we think of ourselves as automobiles that need fuel for our metabolic engines, we should not put protein in our gas tank. For best results, our metabolic engine runs most efficiently on fat or carbohydrates. Eating animal foods has been a vital part of our evolution since the beginning. Katherine Milton, a researcher at UC Berkeley, came to the same conclusion in her paper “The Critical Role Played by Animal Source Foods in Human Evolution,” which states: “Without routine access to animal-source foods, it is highly unlikely that evolving humans could have achieved their unusually large and complex brains while simultaneously continuing their evolutionary trajectory as large, active, and highly social primates. As human evolution progressed, young children in particular, with their rapidly expanding large brains and higher metabolic and nutritional demands relative to adults, would have benefited from concentrated, high-quality foods such as meat." - https://pubmed.ncbi.nlm.nih.gov/14672286/ Skeletons from Greece and Turkey reveal that 12,000 years ago, the average height of hunter-gatherers was five feet, nine inches for men and five feet, five inches for women. But with the adoption of agriculture, adult height plummeted—ending any hope these poor herders had of dunking a basketball or playing competitive volleyball, if such sports had existed at the time. By 3000 B.C., men in this region of the world were only five feet, three inches tall, and women were five feet, reflecting a massive decline in their overall nutritional status. Many studies in diverse populations show a strong correlation between adult height and nutritional quality. A study analyzing male height in 105 countries came to the following conclusion: “In taller nations…consumption of plant proteins declines sharply at the expense of animal proteins, especially those from dairy products. Its highest consumption rates can be found in Northern and Central Europe, with the global peak in male height in the Netherlands (184 cm).” In addition to the decline in height, there is also evidence that Native Americans buried at Dickson Mounds suffered from increased bacterial infections. These infections leave scars on the outer surface of the bone, known as the periosteum, with the tibia being especially susceptible to such damage due to its limited blood flow. Examination of tibias from skeletons found in the mounds shows that after agriculture, the number of such periosteal lesions increased threefold, with a staggering eighty-four percent of bones from this period demonstrating this pathology. The lesions also tended to be more severe and to appear earlier in life in the bones of post-agricultural peoples. https://onlinelibrary.wiley.com/doi/full/10.1111/j.1747-0080.2007.00194.x https://pubmed.ncbi.nlm.nih.gov/10702160/ # Cholesterol Many “doctors” say that consuming saturated fat is harmful to your health, “your veins and arteries will clog with excess fat” “you will have a heart attack if you consume a lot of fat" and many other nonsense, and in exchange recommends that you replace fatty cuts of meat with lean meat and do everything with vegetable oil that causes cancer and makes men effeminate. Your brain is basically composed of fat and water, your neurons are made and repaired with fat, your cells, the basic unit of life, are composed of fat and protein, many of your hormones, especially sexual ones, are made from fat, there is no logical reason not to consume saturated fat other than several false "scientific articles". "The power plant of the cell is the mitochondria, which converts what we eat into energy. Ketones are an energy source derived from fat. Mitochondria prefer fat as energy (ketones) because transforming ketones into energy costs the mitochondria half the effort of using sugar (glucose) for energy." - https://pubmed.ncbi.nlm.nih.gov/28178565/ "With the help of saturated fats, calcium is properly stored in our bones. The interaction between calcium, vitamin D, and parathyroid hormone regulates calcium levels in the body. When there are calcium imbalances in the blood, our bones release calcium into the blood to find homeostasis." - https://www.healthpedian.org/the-role-of-calcium-in-the-human-body/ "The body needs cholesterol to support muscle repair and other cellular functions. This is why when there is cardiovascular disease, we see increased amounts of cholesterol in the area. Cholesterol is not there causing the problem, but the boat carrying fat was docked there for cholesterol and other nutrients to help fight the problem. Plaque is the body's attempt to deal with injury within the blood vessels." - *National Library of Medicine, “Cholesterol,” 2019* "Initially, the Plaque helps blood vessels stay strong and helps the vessels maintain their shape. But with the perpetual cycle of uncontrolled inflammation and leftover debris from cellular repair (cholesterol), over time plaque begins to grow and harden, reducing blood flow and oxygen to the heart. Both inflammation and repair require copious amounts of cholesterol and fats. So the body keeps sending these fatty substances to the site of the plaque — until either repair wins (plaque becomes sclerotic scars in the heart muscle, causing heart failure) or inflammation wins (atherosclerotic heart attack)" - https://pubmed.ncbi.nlm.nih.gov/21250192/ Inflammation in Atherosclerotic Cardiovascular Disease - https://pubmed.ncbi.nlm.nih.gov/21250192/ "Study finds that eating refined carbohydrates led to an increased risk of cardiovascular disease and obesity" - https://pmc.ncbi.nlm.nih.gov/articles/PMC5793267/ # “Meat causes cancer” Most of the misconceptions that red meat causes cancer come from a report by the World Health Organization's International Agency for Research on Cancer (IARC), which was released in 2015. Unfortunately, this report has been widely misrepresented by the mainstream media and is based on some very questionable interpretations of the science it claims to review. A closer look at a 2018 report on its findings reveals that only 14 of the 800 studies were considered in its final conclusions—and every single study was observational epidemiology. Why the other 786 were excluded remains a mystery, and this group included many interventional animal studies that clearly did not show a link between red meat and cancer. Of the fourteen epidemiological studies that were included in the IARC report, eight showed no link between meat consumption and the development of colon cancer. Of the remaining six studies, only one showed a statistically significant correlation between meat and cancer. In epidemiological research, one looks for correlation between two things and the strength of the correlation. Having just one study out of 800 that shows meat causes cancer is a mere fluke and becomes statistically insignificant. Interestingly, this was a study by Seventh-day Adventists in America — a religious group that advocates a plant-based diet. # Microbiota and Fiber I have seen several people and “doctors” saying that eating only meat would destroy your microbiota. And I have come to the conclusion that neither “doctors” nor most people know what a microbiota is. Microbiota is the set of several types of bacteria (millions) that exist in your stomach with the function of breaking down molecules of certain types of food that the body itself cannot get, fiber for example. Many times through the process of fermentation, which is why you have gas after eating your beloved oatmeal. People unconsciously believe that the microbiota is something fixed and unchangeable, but guess what… it is not. Your microbiota is determined by what you eat. If you love eating oatmeal, your microbiota will have a specific set of bacteria that can break down the oat molecule into a size that the body can absorb. If you follow a carnivorous diet, your microbiota will adapt to digest meat. ### Fiber Nutritional guidelines recommend large amounts of fiber in our diet, but what they don't tell you is that we only absorb around 6% of all the vegetable fiber we eat. In other words, it's insignificant! Another argument used by doctors and nutritionists is that it helps you go to the bathroom, but this is also a lie. Fiber doesn't help you evacuate, it forces you to do so. With the huge amount of undigestible food in your stomach (fiber), the intestine begins to force contractions, making this fecal matter go down, making you go to the bathroom. They also raise the argument that fibers are broken down into short-chain fatty acids, such as butyrate (butyric acid), propionate (propionic acid) and acetate (acetic acid). Butyrate is essential because it is the preferred fuel source for the endothelial cells of the large intestine. Butter, cream, and cheese contain butyrate in its absorbable form. Butter is the best source of butyric acid, or butyrate. In fact, the origins of the word butyric acid come from the Latin word *butyro*—the same origins as the word butter. “In 2012, a study in the Journal of Gastroenterology showed that reducing fiber (a precursor to short-chain fatty acids) helped participants with chronic constipation. The study lasted six months, and after two weeks without fiber, these participants were allowed to increase fiber as needed. These participants felt so much relief after two weeks without fiber that they continued without fiber for the entire six-month period. Of the high-fiber, low-fiber, and no-fiber groups, the zero-fiber participants had the highest bowel movement frequency.” - https://pmc.ncbi.nlm.nih.gov/articles/PMC3435786/ ### Bioavailability I said that our body can only absorb 6% of all the fiber we ingest. This is bioavailability, how much the body can absorb nutrients from a given food. Meat is the most bioavailable food on the planet! Grains and vegetables are not only not very bioavailable, but they also contain a huge amount of antinutrients. So if you eat a steak with some beans, you will not be able to absorb the nutrients from the beans, and the antinutrients in them will make it impossible to absorb a large amount of nutrients from the steak. https://pubmed.ncbi.nlm.nih.gov/23107545/ # Lack of nutrients and antioxidants in a carnivorous diet A major concern with the carnivorous diet is the lack of vitamin C, which would consequently lead to scurvy. Vitamin C plays an important role in the breakdown and transport of glucose into cells. In 2000 and 2001, the recommended daily intake of vitamin C effectively doubled. In fact, every 10 to 15 years, there has been a large increase in the recommended daily intake of vitamin C, as happened in 1974 and 1989. Interestingly, also in 1974, sugar prices became so high that high fructose corn syrup was introduced into the US market. Could the increase in readily available glucose foods and foods with high fructose corn syrup be a reason why we need more vitamin C? The question remains…. But this is not a cause for concern for the carnivore, liver is rich in vitamin C. You could easily reach the daily recommendation with liver or any cut of steak. 200-300g of steak already meets your needs and if the theory that the more sugar you eat, the more vitamin C you will get is true, then the more sugar you will eat is true. C is necessary if true, you could easily exceed the daily requirement. Meat and seafood are rich in ALL the nutrients that humans need to thrive. ### Antioxidants It is commonly said that fruits are rich in antioxidants but again this is a hoax, they are actually PRO-oxidants. These are substances that activate the mRF2 pathway of our immune system which causes the body to produce natural antioxidants. The body produces antioxidants, but many occur naturally in foods, Vitamin C, Vitamin E, Selenium and Manganese are all natural antioxidants. High concentrations of antioxidants can be harmful. Remember that high concentrations of antioxidants can increase oxidation and even protect against cancer cells. # Salt Consuming too much salt does not increase blood pressure and therefore increases the risk of heart disease and stroke. Studies show no evidence that limiting salt intake reduces the risk of heart disease. A 2011 study found that diets low in salt may actually increase the risk of death from heart attacks and strokes. Most importantly, they do not prevent high blood pressure. https://www.nytimes.com/2011/05/04/health/research/04salt.html # Sun This is not a dietary issue specifically, but there are things that can I would like to present that is against common sense when talking about the sun. It is common sense to say that the sun causes skin cancer and that we should not expose ourselves to it or, if we are exposed to the sun, use sunscreen, but no study proves that using sunscreen protects us from melanoma and basal cell carcinoma. The types of fatal melanomas usually occur in areas of the body that never see the sun, such as the soles of the feet. https://www.jabfm.org/content/24/6/735 In 1978, the first sunscreen was launched, and the market grew rapidly, along with cases of melanoma. Several studies show that sunscreens cause leaky gut (one of the main factors in chronic inflammation), hormonal dysfunction and neurological dysfunction. https://pubmed.ncbi.nlm.nih.gov/31058986/ If your concern when going out in the sun is skin cancer, don't worry, your own body's natural antioxidants will protect you. When they can no longer protect you, your skin starts to burn. (If you have to stay in the sun for work, for example, a good way to protect yourself is to rub coconut oil on your skin or just cover yourself with a few extra layers of thin clothing and a hat). Sunscreen gives you the false sense of protection by blocking the sunburn, so you stay out longer than your skin can handle, but sunscreens can only block 4% of UVA and UVB rays. www.westonaprice.org/health-topics/environmental-toxins/sunscreens-the-dark-side-of-avoiding-the-sun/ Interestingly, vitamin D deficiency is linked to increased cancer risks. It's a big contradiction to say that the greatest provider of vit. D causes cancer… https://med.stanford.edu/news/all-news/2010/10/skin-cancer-patients-more-likely-to-be-deficient-in-vitamin-d-study-finds.html Important roles of vitamin D: - **Regulation of Bone Metabolism** - Facilitates the **absorption of calcium and phosphorus** in the intestine. - Promotes bone mineralization and prevents diseases such as **osteoporosis**, **rickets** (in children) and **osteomalacia** (in adults). - **Immune Function** - Modulates the immune system, helping to reduce inflammation and strengthen the defense against infections, including **colds**, **flu** and other diseases. - May help reduce the incidence of autoimmune diseases such as **multiple sclerosis** and **rheumatoid arthritis**. - **Muscle Health** - Contributes to muscle strength and the prevention of weakness, especially in the elderly. - Reduces the risk of falls and fractures. - **Cardiovascular Function** - May help regulate blood pressure and heart function, reducing the risk of cardiovascular disease. - **Hormonal Balance** - Influences the production of hormones, including those associated with fertility and the functioning of the endocrine system. - Plays a role in insulin metabolism and glucose sensitivity. - **Brain Function and Mental Health** - Participates in mood regulation, which may reduce the risk of **depression** and improve mental health. - Has been associated with the prevention of neurodegenerative diseases, such as **Alzheimer's**. - **Anticancer Role** - Evidence suggests that vitamin D may inhibit the proliferation of cancer cells, especially in breast, prostate and colon cancers. - **Role in General Metabolism** - Contributes to metabolic health, regulating cellular growth and repair processes. --- I tried to present everything in the simplest and most understandable way possible, but there are things that require prior knowledge to truly understand. Below is a list of books that will show you everything I have shown you in a more technical and in-depth way. ### Book Recommendations https://amzn.to/3EbjVsD https://amzn.to/4awlnBZ All of my arguments have studies to validate them.

![[yedinaya-rossiya-bear.png]] 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... 😏

The 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**.

Hmm so I heard that in order to improve my brain I should try writing… Ok groovy, I’ll give it a go. In all honesty I don’t know what to write, my brain is a jumble of noise and titbits of random knowledge. I likely know more about sound than the average person but as physics goes, I don’t have anything new or profound to add. Air moves and noises happen. Is there really any more to it? I could write some flowery bollocks about refraction, absorption coefficients and reverberation times, or I could write some out there, arty shit but I don’t think that adds any value to anyone. A lot of folks online have very strong beliefs in how the world operates or should operate. Whilst their conviction is strong, there’s also is a large percentage of people who totally disagree with them and think the exact opposite is the answer. That’s quite shit isn’t it? Humans have been around for 100,000 years or so and haven’t worked it out. I wonder what makes the internet celeb so certain they’ve got it right when the next internet celeb completely disagrees? I do my best to avoid any of these cunts but despite running to the obscurest social media platforms they still turn up with their profound statements. Meh. Ideologically I’m leaning toward anarchism but even that seems full of arguments and contradictions and ultimately I don’t think I can be arsed with identifying with any particular ideology. I tried reading some philosophy and struggled with it, although I deep fall into a lovely deep sleep. It’s fair to say I’m not the brightest button in the box. I have a wife, a couple of cats and lots of things that make nosies in my shed. That’s pretty cool right? Well it works for me. So why write this? I clearly wrote in the first sentence that I’m trying to improve my brain, a brain that’s gone through a number to twists and turns, a lot brain altering substances. I own that, no one forced me to. Beside, George Clinton was still smoking crack aged 80, didn’t do him any harm… I’m on the 5th paragraph. I don’t feel any smarter yet and each paragraph is getting shorter, having started from a low base. I guess I’m being too high time preference… Might be a while before I launch my Deep Thought podcasts where myself and a guest talk for 500 hours about the philosophy of money and 13 amp plug sockets. I’ve tortured myself enough. I’m posting this on Nostr where it will never go away.. lol. If you got this far, I congratulate/commiserate you and wish you a wonderful day.

President 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. [Sauce](https://www.stripes.com/theaters/europe/2025-01-24/trump-europe-troop-cuts-16590074.html)

A Indústria Pornográfica se caracteriza pelo investimento pesado de grandes empresários americanos, desde 2014. Na década de 90, filmes pornográficos eram feitos às coxas. Era basicamente duas pessoas fazendo sexo amador e sendo gravadas. Não tinha roteiro, nem produção, não tinha maquiagem, nada disso. A distribuição era rudimentar, os assinantes tinham que sair de suas casas, ir até a locadora, sofrer todo tipo de constrangimento para assistir a um filme pornô. No começo dos anos 2000, o serviço de Pay Per View fez o número de vendas de filmes eróticos (filme erótico é bem mais leve) crescer mas nada se compara com os sites de filmes pornográficos por assinatura. Com o advento dos serviços de Streaming, os sites que vendem filmes por assinatura se estabeleceram no mercado como nunca foi visto na história. Hoje, os Produtores usam produtos para esticar os vasos sanguíneos do pênis dos atores e dopam as atrizes para que elas aguentem horas de gravação (a Série Black Mirror fez uma crítica a isso no episódio 1 milhão de méritos de forma sutil). Além de toda a produção em volta das cenas. Que são gravadas em 4K, para focar bem as partes íntimas dos atores. Quadros fechados, iluminação, tudo isso faz essa Indústria ser "Artística" uma vez que tudo ali é falso. Um filme da Produtora Vixen, por exemplo, onde jovens mulheres transam em mansões com seus empresários estimula o esteriótipo da mina padrão que chama seu chefe rico de "daddy" e seduz ele até ele trair a esposa. Sites como xvídeos, pornHub e outros nada mais são do que sites que salvam filmes dessas produtoras e hospedam as cenas com anúncios e pop-ups. Alguns sites hospedam o filme inteiro "de graça". Esse tipo de filme estimula qualquer homem heterosexual com menos de 30 anos, que não tem o córtex frontal de seu cérebro totalmente desenvolvido (segundo estudos só é completamente desenvolvido quando o homem chega aos 31 anos). A arte Pornográfica faz alguns fantasiarem ter relação sexual com uma gostosa americana branquinha, até escraviza-los. Muitos não conseguem sair do vício e preferem a Ficção à sua esposa real. Então pare de se enganar e admita. A Pornografia faz mal para a saúde mental do homem. Quem sonha em ter uma transa com Lana Rhodes, deve estar nesse estágio. Trata-se de uma atriz (pornstar) que ganhou muito dinheiro vendendo a ilusão da Arte Pornografica, como a Riley Reid que só gravava para grandes Produtoras. Ambas se arrependeram da carreira artística e agora tentam viver suas vidas como uma mulher comum. As próprias atrizes se consideram artistas, como Mia Malkova, chegou a dizer que Pornografia é a vida dela, que é "Lindo e Sofisticado." Mia Malkova inclusive faz questão de dizer que a industria não escravisa mulheres jovens. Trata-se de um negócio onde a mulher assina um contrato com uma produtora e recebe um cachê por isso. Diferente do discurso da Mia Khalifa em entrevista para a BBC, onde diz que as mulheres são exploradas por homens poderosos. Vai ela está confundindo o Conglomerado Vixen com a Rede Globo ou com a empresa do Harvey Weinstein. Enfim, se você é um homem solteiro entre 18 e 40 anos que já consumiu ou que ainda consome pornografia, sabia que sofrerá consequências. Pois trata-se de "produções artísticas" da indústria audiovisual que altera os níveis de dopamina do seu cérebro, mudando a neuroplasticidade e diminuindo a massa cinzenta, deixando o homem com memória fraca, sem foco e com mente nebulosa. Por que o Estado não proíbe/criminaliza a Pornografia se ela faz mal? E desde quando o Estado quer o nosso bem? Existem grandes empresarios que financiam essa indústria ajudando governos a manterem o povo viciado e assim alienado. É um pão e circo, só que muito mais viciante e maléfico. Eu costume dizer aos meus amigos que existem grandes empresários jvdeus que são donos de grandes Produtoras de filmes pornográficos como o Conglomerado Vixen. Então se eles assistem vídeos pirateados de filmes dessas produtoras, eles estão no colo do Judeu.

## Bitcoin: 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: 1. 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. 2. 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. 3. 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: 1. **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. 2. **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). 3. **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. 4. **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. 5. **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. 6. **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: 1. Usar esse poder para fraudar o sistema, como reverter transações e roubar pagamentos. 2. 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: 1. 0,03 BTC 2. 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: 1. **Chaves Públicas Anônimas**: Cada transação utiliza um par de chaves diferentes, dificultando a associação com um proprietário único. 2. **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. --- Faça o download do whitepaper original em português: https://bitcoin.org/files/bitcoin-paper/bitcoin_pt_br.pdf

The 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. ###

**Einleitung**\ \ Schwierige Dinge einfach zu erklären ist der Anspruch von ELI5 (explain me like I'm 5). Das ist in unserer hoch technisierten Welt dringend erforderlich, denn nur mit dem Verständnis der Technologien können wir sie richtig einsetzen und weiter entwickeln.\ Ich starte meine Serie mit Nostr, einem relativ neuen Internet-Protokoll. Was zum Teufel ist ein Internet-Protokoll? Formal beschrieben sind es internationale Standards, die dafür sorgen, dass das Internet seit über 30 Jahren ziemlich gut funktioniert. Es ist die Sprache, in der sich die Rechner miteinander unterhalten und die auch Sie täglich nutzen, vermutlich ohne es bewusst wahrzunehmen. http(s) transportiert ihre Anfrage an einen Server (z.B. Amazon), und html sorgt dafür, dass aus den gelieferten Daten eine schöne Seite auf ihrem Bildschirm entsteht. Eine Mail wird mit smtp an den Mailserver gesendet und mit imap von ihm abgerufen, und da alle den Standard verwenden, funktioniert das mit jeder App auf jedem Betriebssystem und mit jedem Mail-Provider. Und mit einer Mail-Adresse wie <roland@pareto.space> können sie sogar jederzeit umziehen, egal wohin. **Cool, das ist state of the art!** Aber warum funktioniert das z.B. bei Chat nicht, gibt es da kein Protokoll? Doch, es heißt IRC (Internet Relay Chat → merken sie sich den Namen), aber es wird so gut wie nicht verwendet. Die Gründe dafür sind nicht technischer Natur, vielmehr wurden mit Apps wie Facebook, Twitter, WhatsApp, Telegram, Instagram, TikTok u.a. bewusst Inkompatibilitäten und Nutzerabhängigkeiten geschaffen um Profite zu maximieren.  **Warum Nostr?** Da das Standard-Protokoll nicht genutzt wird, hat jede App ihr eigenes, und wir brauchen eine handvoll Apps um uns mit allen Bekannten auszutauschen. Eine Mobilfunknummer ist Voraussetzung für jedes Konto, damit können die App-Hersteller die Nutzer umfassend tracken und mit dem Verkauf der Informationen bis zu 30 USD je Konto und Monat verdienen. Der Nutzer ist nicht mehr Kunde, er ist das Produkt! Der Werbe-SPAM ist noch das kleinste Problem bei diesem Geschäftsmodell. Server mit Millionen von Nutzerdaten sind ein “honey pot”, dementsprechend oft werden sie gehackt und die Zugangsdaten verkauft. 2024 wurde auch der Twitter-Account vom damaligen Präsidenten Joe Biden gehackt, niemand wusste mehr wer die Nachrichten verfasst hat (vorher auch nicht), d.h. die Authentizität der Inhalte ist bei keinem dieser Anbieter gewährleistet. Im selben Jahr wurde der Telegram-Gründer in Frankreich in Beugehaft genommen, weil er sich geweigert hatte Hintertüren in seine Software einzubauen. Nun kann zum Schutz **"unserer Demokratie”** praktisch jeder mitlesen, was sie mit wem an Informationen austauschen, z.B. darüber welches Shampoo bestimmte Politiker verwenden.   Und wer tatsächlich glaubt er könne Meinungsfreiheit auf sozialen Medien praktizieren, findet sich schnell in der Situation von Donald Trump wieder (seinerzeit amtierender Präsident), dem sein Twitter-Konto 2021 abgeschaltet wurde (Cancel-Culture). Die Nutzerdaten, also ihr Profil, ihre Kontakte, Dokumente, Bilder, Videos und Audiofiles - gehören ihnen ohnehin nicht mehr sondern sind Eigentum des Plattform-Betreibers; lesen sie sich mal die AGB's durch. Aber nein, keine gute Idee, das sind hunderte Seiten und sie werden permanent geändert. Alle nutzen also Apps, deren Technik sie nicht verstehen, deren Regeln sie nicht kennen, wo sie keine Rechte haben und die ihnen die Resultate ihres Handelns stehlen. Was würde wohl der Fünfjährige sagen, wenn ihm seine ältere Schwester anbieten würde, alle seine Spielzeuge zu “verwalten” und dann auszuhändigen wenn er brav ist? “Du spinnst wohl”, und damit beweist der Knirps mehr Vernunft als die Mehrzahl der Erwachsenen. \ \ **Resümee:** keine Standards, keine Daten, keine Rechte = keine Zukunft!  \ **Wie funktioniert Nostr?** Die Entwickler von Nostr haben erkannt dass sich das Server-Client-Konzept in ein Master-Slave-Konzept verwandelt hatte. Der Master ist ein Synonym für Zentralisierung und wird zum **“single point of failure”**, der zwangsläufig Systeme dysfunktional macht. In einem verteilten Peer2Peer-System gibt es keine Master mehr sondern nur gleichberechtigte Knoten (Relays), auf denen die Informationen gespeichert werden. Indem man Informationen auf mehreren Relays redundant speichert, ist das System in jeglicher Hinsicht resilienter. Nicht nur die Natur verwendet dieses Prinzip seit Jahrmillionen erfolgreich, auch das Internet wurde so konzipiert (das ARPAnet wurde vom US-Militär für den Einsatz in Kriegsfällen unter massiven Störungen entwickelt). Alle Nostr-Daten liegen auf Relays und der Nutzer kann wählen zwischen öffentlichen (zumeist kostenlosen) und privaten Relays, z.B. für geschlossene Gruppen oder zum Zwecke von Daten-Archivierung. Da Dokumente auf mehreren Relays gespeichert sind, werden statt URL's (Locator) eindeutige Dokumentnamen (URI's = Identifier) verwendet, broken Links sind damit Vergangenheit und Löschungen / Verluste ebenfalls.\ \ Jedes Dokument (Event genannt) wird vom Besitzer signiert, es ist damit authentisch und fälschungssicher und kann nur vom Ersteller gelöscht werden. Dafür wird ein Schlüsselpaar verwendet bestehend aus privatem (nsec) und öffentlichem Schlüssel (npub) wie aus der Mailverschlüsselung (PGP) bekannt. Das repräsentiert eine Nostr-Identität, die um Bild, Namen, Bio und eine lesbare Nostr-Adresse ergänzt werden kann (z.B. <roland@pareto.space> ), mehr braucht es nicht um alle Ressourcen des Nostr-Ökosystems zu nutzen. Und das besteht inzwischen aus über hundert Apps mit unterschiedlichen Fokussierungen, z.B. für persönliche verschlüsselte Nachrichten (DM → OxChat), Kurznachrichten (Damus, Primal), Blogbeiträge (Pareto), Meetups (Joinstr), Gruppen (Groups), Bilder (Olas), Videos (Amethyst), Audio-Chat (Nostr Nests), Audio-Streams (Tunestr), Video-Streams (Zap.Stream), Marktplätze (Shopstr) u.v.a.m. Die Anmeldung erfolgt mit einem Klick (single sign on) und den Apps stehen ALLE Nutzerdaten zur Verfügung (Profil, Daten, Kontakte, Social Graph → Follower, Bookmarks, Comments, etc.), im Gegensatz zu den fragmentierten Datensilos der Gegenwart.\ \ **Resümee:** ein offener Standard, alle Daten, alle Rechte = große Zukunft!  \ **Warum ist Nostr die Zukunft des Internet?** “Baue Dein Haus nicht auf einem fremden Grundstück” gilt auch im Internet - für alle App-Entwickler, Künstler, Journalisten und Nutzer, denn auch ihre Daten sind werthaltig. Nostr garantiert das Eigentum an den Daten, und überwindet ihre Fragmentierung. Weder die Nutzung noch die kreativen Freiheiten werden durch maßlose Lizenz- und Nutzungsbedingungen eingeschränkt. Aus passiven Nutzern werden durch Interaktion aktive Teilnehmer, Co-Creatoren in einer Sharing-Ökonomie **(Value4Value)**. OpenSource schafft endlich wieder Vertrauen in die Software und ihre Anbieter. Offene Standards ermöglichen den Entwicklern mehr Kooperation und schnellere Entwicklung, für die Anwender garantieren sie Wahlfreiheit. Womit wir letztmalig zu unserem Fünfjährigen zurückkehren. Kinder lieben Lego über alles, am meisten die Maxi-Box “Classic”, weil sie damit ihre Phantasie im Kombinieren voll ausleben können. Erwachsene schenken ihnen dann die viel zu teuren Themenpakete, mit denen man nur eine Lösung nach Anleitung bauen kann. “Was stimmt nur mit meinen Eltern nicht, wann sind die denn falsch abgebogen?" fragt sich der Nachwuchs zu Recht. Das Image lässt sich aber wieder aufpolieren, wenn sie ihren Kindern Nostr zeigen, denn die Vorteile verstehen sogar Fünfjährige.  \ **Das neue Internet ist dezentral. Das neue Internet ist selbstbestimmt. Nostr ist das neue Internet.** <https://nostr.net/> \ <https://start.njump.me/> **Hier das Interview zum Thema mit Radio Berliner Morgenröte** <https://www.podbean.com/ew/pb-yxc36-17bb4be>

In the world of networking, two fundamental models serve as the backbone for communication protocols and standards: the OSI model and the TCP/IP model. Both models are quite similar, providing frameworks for how data is transmitted across networks at various stages of the process. Understanding these models is crucial for anyone working in IT, cybersecurity, or any related tech field. But what exactly are they? # The OSI Model The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven distinct layers. Each layer is responsible for specific tasks, such as data encapsulation, error detection, and routing. The layers of the OSI model are as follows: 1. **Physical Layer:** This layer deals with the physical connection between devices, such as cables and network interfaces. 2. **Data Link Layer:** Responsible for node-to-node communication, this layer ensures data integrity and manages access to the physical medium. 3. **Network Layer:** The network layer handles routing and forwarding of data packets between different networks. 4. **Transport Layer:** This layer provides end-to-end communication services for applications, including error detection and flow control. 5. **Session Layer:** Manages sessions between applications, establishing, maintaining, and terminating connections. 6. **Presentation Layer:** Responsible for data translation, encryption, and compression to ensure compatibility between different systems. 7. **Application Layer:** The topmost layer that interacts directly with applications and end-users, providing network services such as email and file transfer. Now, that's a lot to remember. So, an easy acronym you can use to remember these 7 layers is *"Please Do Not Touch Steve's Pet Alligator."* It's helped me quite a bit in trying to pinpoint a specific layer. Also, keep in mind that the layers are typically inverted from what you see above, with Layer 7 being at the top of the stack and Layer 1 being at the bottom. # The TCP/IP Model On the other hand, the TCP/IP (Transmission Control Protocol/Internet Protocol) model is a more streamlined approach to networking, consisting of only four layers: 1. **Link Layer:** Corresponding to the OSI model's data link and physical layers, the link layer deals with the physical connection and data framing. 2. **Internet Layer:** Similar to the OSI model's network layer, the internet layer focuses on routing packets across different networks. 3. **Transport Layer:** Combines the functions of the OSI model's transport and session layers, providing reliable data transfer services. 4. **Application Layer:** Equivalent to the OSI model's top three layers, the application layer in TCP/IP handles network services for applications. While the OSI model is more detailed and theoretical, the TCP/IP model is practical and widely used in modern networking. It's also a bit easier to remember than the OSI model. And, similar to the OSI model, the TCP/IP model is typically visualized with Layer 4 at the top of the stack and Layer 1 at the bottom, unlike what you see above. # Conclusion Both the TCP/IP and OSI models play essential roles in understanding how data is transmitted across networks. By grasping the functions of each layer and their interactions, network professionals can troubleshoot issues, design efficient networks, and ensure seamless communication between devices.

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