BITCOIN RAILS #61: QUANTUM CRYPTOGRAPHY FOR BITCOIN | with Dan Boneh Dan Boneh 🔗 YOUTUBE: 🌿 SPOTIFY: One of the most prolific and influential cryptographers in the world, it’s difficult to fully quantify the impact that Dan Boneh has had on Bitcoin and digital assets more broadly. Through both his own research and his mentorship of some of the space’s most important contributors — e.g. Andrew Poelstra, Benedikt Bünz ☕️, and Robin Linus — few people have done more to shape the cryptographic foundations underlying modern blockchains and digital finance. More recently, Dan co-authored Google's widely discussed paper, “Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities,” which reduced prior estimates of the resources required to run Shor’s algorithm against the elliptic-curve cryptography used by Bitcoin. The paper reignited debate around quantum computing timelines and the long-term security assumptions behind modern cryptocurrencies. In this episode of Bitcoin Rails, Dan and I discuss the current state of quantum computing, its potential implications for Bitcoin, and how he believes the Bitcoin community should think about preparing for a post-quantum future over the coming decade and beyond. And yes, Dan shares his take on the “when quantum” question in the interview, among other key perspectives. This episode of Bitcoin Rails is brought to you by my NEW sponsors: LayerTwo Labs LayerTwo Labs — developing research, software, and technologies for scaling Bitcoin via the integration of Drivechains (BIP 300/301) Hashi on Sui — a primitive for executing Bitcoin Defi transactions, without having to trust a federated bridge or other centralized entity BitBox BitBox — an open-source Bitcoin-only hardware wallet, with smooth UX and no compromises on security.

BITCOIN RAILS #59: Post-Quantum Bitcoin Signatures (+ their tradeoffs) | with BIP 360 co-author Ethan ✨ is on BlueSky✨ Heilman 🐱 and Blockstream Head of Research Jonas Nick 🔗 YOUTUBE: 🌿 SPOTIFY: According to BIP 360 co-author Ethan Heilman, Bitcoin needs a minimum of two soft forks to become quantum resistant: P2MR (or an output type that can safely execute PQ signatures) + a post-quantum checksig (signature scheme). Ethan and the BIP 360 team (including myself and Hunter Beast 🕯️) introduced the P2MR part via a BIP 360 update late last year—but the question remains, what’s the most appropriate PQ signature scheme for Bitcoin? They all have substantive tradeoffs, but hash-based signatures seem to be leading technical discourse—likely due to recent optimizations by Jonas Nick and the broader Blockstream research team. It was an honor to sit down with both of these men - arguably the two most influential and productive cryptographers in Bitcoin quantum mitigation right now - for an in-depth review of the leading PQ signature schemes and a temperature check on Bitcoin’s post-quantum planning process. TBH, if you want to skip the noise and jump straight to the signal on quantum, this is the interview to watch. In this episode, we discuss: - What needs to happen at the soft fork, infra, and mitigation levels to fully quantum-harden Bitcoin - Recent updates to BIP 360 + breakdown of the leading hash-based signatures schemes for Bitcoin (SHRINCS + SHRIMPS) - Why we may actually get consensus around a stateful scheme for Bitcoin - Comparisons of hash-based signatures vs Lattice and Isogeny-based schemes - Assessing the risks of both waiting too long and acting too fast (and why quantum is a better threat to be facing than a potential classical attack) This episode of Bitcoin Rails is brought to you by my NEW sponsors: - LayerTwo Labs LayerTwo Labs — developing research, software, and technologies for scaling Bitcoin via the integration of Drivechains (BIP 300/301) - Hashi on Sui — a primitive for executing Bitcoin Defi transactions, without having to trust a federated bridge or other centralized entity - BitBox BitBox — an open-source Bitcoin-only hardware wallet, with smooth UX and no compromises on security.

BITCOIN RAILS #38: Two Forces That Could Break Bitcoin: AI vs Quantum I with Martin Shkreli 🔗 YOUTUBE: 🌿 SPOTIFY: A couple months ago, I co-hosted an X space with LayerTwo Labs re: “Should Bitcoiners care about quantum computing?” You can imagine our surprise when (in?)famous tech investor Martin Shkreli arrived to share that he’s been researching this very question for years… and dropped that he’s been personally considering raising funds to hire a team of mathematicians to hack Satoshi’s Coins. In this episode, Martin and I explore the limits of Bitcoin’s security model and the two forces he believes could potentially challenge it: a computational path driven by advances in quantum hardware, and/or a mathematical path fueled by AI-assisted discovery. This interview additionally shares takes on: - Why hacking Bitcoin would be the "ultimate" mathematical achievement—and why hacking Satoshi’s coins should be considered a “bug bounty” for Bitcoin - Why quantum may be more problematic for Bitcoin than for the traditional tech world (e.g. why quantum doesn’t likely threaten NVIDIA) - The little known history of Bitcoin’s “overflow bug” (yup, Bitcoin *has* been hacked before… an exploit corrected by hard fork). - And of course, why mathematicians do their deepest work in prison 😉 As always, this episode of Bitcoin Rails can be viewed on YouTube or Spotify via the link available in my bio—and is brought to you with the help of my incredible partners: - Best In Slot (Best in Slot | BRC2.0 🧑‍🍳) – the leading API for Ordinals and BRC20 data aggregation and indexing - Spark (Lightspark) – a statechains implementation leading the path towards institutional adoption of Bitcoin-powered payments - Citrea (Citrea) – the leading Bitcoin rollup technology and contributor to the BitVM alliance 📷 Timestamps 00:00 Intro 02:57 Quantum Supremacy and Google’s Breakthroughs 05:02 Bitcoin’s Cryptographic Vulnerabilities 08:24 Studying Math and Cryptography Behind Bars 20:04 Governance and the Culture of Bitcoin Development 26:29 The Future of Quantum and AI in Cryptography 37:42 Hardware Challenges and Fidelity in Quantum 47:57 Game Theory and the Quantum Race 01:04:08 Bitcoin Recovery and the Quantum Security Question 01:08:38 Mathematical Challenges in Breaking Cryptography 01:15:08 The Role of AI in Future Mathematical Breakthroughs

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.
