We (@xVFcrypto and I) won the @satsconf hackathon! I'm very grateful to the @Blockstream team for the Liquid & Simplicity bootcamp they held just before the event. It was essential for our project. A thanks also goes to @lucasdcf for organizing such an amazing event. I'll continue to work on MareNostrum.

Happy birthday @halfin

Yes.

@lorenzolfm I wish astronauts would become the new icons and celebrities for the youth. An astronaut is much cooler than a rapper, soccer player, or digital influencer.

I spent the evening looking into quantum computing timelines as a non-expert in quantum computing. Here is what I’ve learned: We currently have machines with ~1,000–1,500 physical qubits at error rates around 10⁻³, and Google’s algorithm requires ~500,000 physical qubits operating coherently together with surface code error correction, yoked qubit storage, magic state cultivation producing ~500K T states per second, and reaction-limited execution at 10μs cycle times — none of which has been demonstrated beyond small-scale proof-of-concept experiments. Scaling from where we are to where this needs to be isn’t a matter of incremental improvement along a Moore’s Law curve; it requires solving qualitatively new engineering problems in qubit fabrication yield, correlated error suppression across a massive chip (or multi-chip interconnects that don’t exist yet), cryogenic wiring and control electronics for half a million qubits, real-time classical decoding at the required throughput, and sustained coherence of a “primed” quantum state across minutes of wall-clock time — any one of which could prove to be a multi-year bottleneck, and all of which must be solved simultaneously.​​​​​​​​​​​​​​​​ Given the above, I just don’t see how we’re going to get to a cryptographically relevant quantum computer by 2030, especially given that we need a ~350× increase in physical qubit count with simultaneously tighter error correlations, an entirely new cryogenic control and wiring architecture to address half a million qubits, real-time decoding infrastructure that doesn’t exist yet, magic state distillation factories operating at industrial throughput, and multi-minute coherent idle times for primed states — and historically, solving even one of these at scale has taken the field the better part of a decade.

Insane to wake up to this. I’ve grown up with photos of the orb of the earth from spacecraft. But they were all from before I was born. First time seeing a photo of this fresh of the wire, such a crazy feeling

Floresta v0.9.0 is out. This release aligns our networking layer with the Utreexo messaging flow (BIP-0183), while improving validation, testing, and performance across the stack. Checkout our in-depth post for more info getfloresta.org/blog/release-v…

It's not FUD to point out that significant advancements are being made in quantum computing. It is FUD to make claims that ECC will be broken in X years. No one can honestly make predictions about the rate of progress we'll see in the future, and many breakthroughs are needed.

So everyone's talking about Google Quantum AI’s new research paper, “Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities: Resource Estimates and Mitigations.” Cue the predictable Bitcoin quantum FUD: “Why haven’t the devs fixed this already?!” Reality is, it’s not a simple patch. Post-quantum signatures come with serious tradeoffs and Bitcoin faces unique constraints that general tech and web apps don’t. Post-quantum signatures are generally much larger transaction sizes - often 5–50× or more in the signature-heavy parts → higher fees, more compute. Hardware wallets would need a big shift. The choice of scheme (stateless, stateful, or hybrid) would change how we custody coins. HD wallets, watch-only wallets, FROST, MuSig2, silent payments… some of the privacy and UX wins we love today could be gone, degrade or require clunky workarounds. Bitcoin has to stay decentralized: small blocks, permissionless validation. Web servers can throw bigger payloads around; Bitcoin can’t without sacrificing the very properties that make it Bitcoin. Even “standard” post-quantum schemes like ML-DSA (which Android is integrating) produce signatures 35–66× larger than today’s ~70-byte ECDSA signatures, making them too heavy for Bitcoin’s tight constraints on block space, fees, and hardware. That’s why researchers like @n1ckler (and @blksresearch) are doing vital work right now: exploring the right tradeoffs for Bitcoin specifically. Hash-based crypto? Lattice-based? Something else? Which Bitcoin-optimized forms of SPHINCS make sense? SHRINCS (tiny ~324-byte stateful signatures with static backups) or SHRIMPS (for multi-device stateful setups)? How many times will a user sign with the same key? Can we assume user devices can securely maintain state, or do we need fully stateless fallbacks? Would we expand the block size with some kind of quantum witness discount? What do we do about quantum-vulnerable coins? These are the hard, Bitcoin-specific questions that matter. Practical steps are already being taken. BIP 360, proposed by @cryptoquick, @Ethan_Heilman, and @isabelfoxenduke, is a thoughtful first step: it introduces a new Pay-to-Merkle-Root (P2MR) output type that gives us Taproot-like functionality without the quantum-vulnerable keypath spend. It’s designed as an enabling primitive — conservative, upgradable, and focused on reducing address exposure risks while the ecosystem figures out the heavier lifting of actual post-quantum signatures. Bitcoin builders have spent 15+ years improving what is otherwise a very clunky experience in a decentralized environment. Rushing big protocol shifts risks breaking that. This isn’t something to knee-jerk “just fix.” It deserves careful, ongoing research and exploration, not panic. That said, informed skeptics like @reardencode and @bergealex4 are also right to push back. The paper improves resource estimates for breaking secp256k1 (fewer logical qubits, potentially minutes-long attacks on a hypothetical machine), but as @reardencode notes, it’s still theorycrafting: we’d need a large-scale fault-tolerant quantum computer with hundreds of thousands of physical qubits maintaining coherence for minutes — something far beyond today’s best devices (hundreds of qubits coherent for microseconds). A true CRQC capable of breaking ECDSA by 2029 (or even soon after) remains a big maybe. Bitcoin's strength is in deliberate, methodical and conservative steps to address threats.

@iamspritz Make Rio great again.

Rio Atlântico. I have a plan. Straight out from what worked in Europe, we're gonna make this city once again not only look good but feel good.

It was very nice to meet other bitcoiner students doing cool things.

Got a cortisol spike from it.
