Open source mining firmware + AI = unstoppable. ⚡ For years, people have tried to chase excess solar power with bitcoin miners. Stock firmware doesn't let you adjust power at all. Third-party firmware was too slow, some even restarted mining every time you changed the target. 256 Foundation &...

BITCOIN RAILS #46: BITCOIN MINING IN THE AGE OF AI | with MARA CEO Fred Thiel 🔗 YOUTUBE: 🌿 SPOTIFY: In response to the AI-driven shock in global demand for computing power, large players in the Bitcoin mining industry have been forced to make significant strategic shifts to remain competitive. MARA — the largest Bitcoin miner in the world by hashrate — is emerging as one of the more well-positioned beneficiaries of these changing tides, having transitioned from an “asset-light” strategy (via hosted mining at third-party facilities) to an “asset-heavy” approach (owning its own land, power, and infrastructure) just ahead of the AI compute wave in 2024/25. I sat down with MARA CEO Fred Thiel to discuss how these shifting industry dynamics are playing out in practice — as well as his perspective on how key mining-related security and infrastructure issues may evolve in the coming months and years. In this episode, we cover: — How MARA scaled from near-zero hash rate in 2020 to the largest Bitcoin miner globally by the end of 2023 — Key differences between operating Bitcoin mining facilities versus AI data centers, and where the two models meaningfully intersect — Why ownership of power generation — rather than reliance on PPAs — may represent a durable competitive edge for miners and AI data center operators over time — Why Bitcoin may be entering its “IPO phase,” and why recent price corrections could reflect increasing market maturity rather than structural weakness We also explore more technical and often under-discussed topics, such as heat reuse, open-source mining technologies, and the implications of US policy goals around Bitcoin mining. This episode offers a grounded, operator-level view of where Bitcoin mining is headed, informed by one of the most influential leaders in the public mining sector. This episode of Bitcoin Rails is powered by: — Best In Slot (Best in Slot | BRC2.0 🧑‍🍳) — the leading API for Ordinals and BRC-20 data aggregation and indexing. — Spark (Lightspark) — a statechains implementation advancing Bitcoin-powered payments. — Citrea (Citrea | Mainnet Live 🍊🍋) — a leading Bitcoin rollup technology and BitVM alliance contributor.

Bitcoin Mining Heat-Capture Season 2025: HeatHarvest / Proof-of-Growth, Purple Sweet Potatoes & Crawfish. vlog 1: Dry Run . We’re excited to launch the first of many Bitcoin Mining Heat-Capture Seasons. Each year, we’ll showcase a fresh set of projects that turns Bitcoin mining heat into real-world impact. For 2025, our focus is global food sustainability. Even now, many communities and regions lack reliable food security and access to modern financial tools. Bitcoin mining can help address both. By capturing miner heat, people can grow food locally while earning bitcoin and connecting to global commerce. Imagine a remote village with a short growing season but access to electricity or generators. With Bitcoin-heated cultivation, that community can extend the growing season indefinitely, feed itself, and use Bitcoin mining rewards to upgrade infrastructure, more reliable power, better facilities, and a higher quality of life. Also Bitcoiners are always wanting to be more self-sustaining, to know where their food comes from, and to avoid synthetic inputs common in industrial agriculture and commercial food supply chains. In Bitcoin we say, “Don’t trust, verify.” Apply it to food: grow it yourself and verify every input. “Proof-of-Work” your own food, no trust required, just quality, organic, self-sustaining harvests powered by Bitcoin heat. Throughout this season, we’ll share practical, open resources, designs, build guides, and results so anyone can adapt Bitcoin mining heat to their own goals. Follow along, grow with us, and let’s turn hashrate into harvest. Huge thanks to our sponsors for providing the tools, resources, and equipment that accelerated this season. Interested in sponsoring? There’s still time DM or email us. Together, we can address real-world problems with Bitcoin mining heat.

An interesting thought I had on my morning walk. Filters on their own are not effective to censor all spam from motivated attackers, that's true. But filters do make spam more prone to censorship at the mining pool level. Miners can get away with mining transactions that are used for illegal purposes because they have plausible deniability: they don't know what they are used for, they are "just including what's relayed" by the p2p network. But with many forms of spam, such as OP_RETURN, it is not so. They do not have plausible deniability. MARA is perfectly happy inscribing NFTs and non-standard troll OP_RETURNS via its slipstream service. Since they are legally low risk, it makes sense for them to profit from it. However, if I was to submit something really nasty like torrent links to child pornography (or child porn jpegs) or Mein Kampf (illegal in many countries) MARA could not plausibly deny that it is publishing and distributing illegal content. It’s right there in the OP_RETURN for everyone to see. Consequently they would probably not allow it. If they did, they would get in trouble. And it would be much easier for the content submitters to get caught. If nonstandard node relay software (i.e. libre relay) started being abused by pedophiles, its likely mining pools would just ban these types of higher-risk peers. Of course the pedophiles can always run their own mining pools and get a few transactions every month: bitcoin would remain censorship resistant if you are patient enough. But now, with relaxation of standardness rules and “filters” anybody can easily publish blatantly illegal content as OP_RETURNS and get it relayed to a mining pool in a more censorship-resistant way, cheaper and more effective. Good? Bad? It's possible mining pools are going to have no choice but to develop software that analyzes transaction OP_RETURN to assess what they will publish or not. They may develop content moderation policies, because the illegality of the OP_RETURN content will be blatant and they will have no plausible deniability. I'm honestly pleasantly surprised that miners haven't already done this for obviously "higher risk" transactions like coinjoin. However coinjoin transactions are not illegal per se, and there is very wide international support for financial privacy. Not so for child porn. Once miners start developing software to moderate what transactions go in the blockchain, a Pandora's box is opened: if you can easily filter transactions that have illegal data in the OP_RETURN, why are you allowing whirlpool tx0? Why are you allowing coinjoins? Why are you allowing sanctioned addresses? Ironically, the attempt at making spam transactions less prone to censorship might make economic transactions more prone to censorship. Bitcoin is censorship resistant from a network perspective because anybody can mine anonymously. This censorship resistance is compounded when large centralized mining pools and mining farms have plausible deniability that the transactions they mine aren't blatantly illegal because they are anonymous (“there is no way to know”). The more mining is centralized, the more this component of censorship resistance matters. Non-monetary content puts that aspect at risk. I'm not sure I’m right, but I don't think this idea has been widely discussed. The only thing that can prevent certain txs formats (i.e. the low hanging fruit spam vectors like OP_RETURN) from making it into the chain is consensus rules. Yes I'm aware spammers will always find a way to get spam in eventually. It would be sad to see fork-level consensus to ban OP_RETURN entirely, because there are reasonable harm-reducing use cases for it (e.g. open timestamps). We are nowhere near consensus on restriction spam vectors at a consensus level, not even close. But who knows after 10 years of child porn being distributed via the Bitcoin network nodes and miners both will have had enough. It would be interesting to watch this play out.

Mo Gawdat believes up to 30% of jobs in certain sectors could disappear by 2028. That stopped me in my tracks. Mo was one of the first people to come on this podcast and warn me about AI, long before most of the world was talking about it. At the time, it felt early. Now, it feels like the world is catching up to what he was seeing. I’m still trying to understand what AI actually means for our lives. Not just whether it can write emails, create images or make us more productive. I mean what it does to jobs. What it does to power. What it does to education. What it does to human connection… That’s why I wanted to have this discussion with Mo again. What makes Mo worth listening to is that he saw these systems inside Google years before most of us had even heard the term AI. His book *Scary Smart* now feels like it was written for this exact moment. Let me explain why this discussion matters. Mo believes we’re not just entering an AI revolution. We’re entering a period where AI, robotics, economics, surveillance, digital currencies and global instability are all colliding at the same time. That’s a lot for any of us to process. We spoke about: - The jobs Mo believes are most at risk from AI. - Why he believes that AI is actually underhyped! - The mistake almost everyone is making with ChatGPT. - The prediction that changed even his own view of the future. The part that stayed with me was this idea that human connection may become the real currency. Because if AI can produce the information, write the report, analyse the data, then what is left? I don’t think this conversation gives neat answers. That’s probably why it’s worth watching. It helped me think more honestly about what’s coming.
