Three years since the first flight of Starship, the next generation is here. New ship. New booster. New engines. New pad and new test site. SpaceX engineers are working to solve one of the most difficult engineering challenges in history: developing a fully, rapidly reusable rocket

in the face of quantum adversary, a commonly discussed emergency soft fork for Bitcoin would be to disable the Taproot keyspend path (https://t.co/AQo96JiYQ7), effectively turning it into something that resembling BIP-360

assuming an existing precautionary soft-fork to add a pq signature scheme, this would safely allow holders to maintain unilaterally custody of their funds

a downside to this proposal is that any keyspend-only (normal schnorr sig) would be locked indefinitely

inspired by https://t.co/rBJMpJ8sR0, I set out to address the option problem in section 6, to create a variant of seed-lifting that doesn't reveal the wallet's master secret! 🤓

the end result is a zk-STARK proof that proves: "public key P was generated using a private key k, which itself was derived via BIP-32/BIP-86 with a master wallet secret S"

this generalizes beyond Taproot, and would allow the rightful owners of any BIP-32 derived wallets to move their funds in het case of a spend disabeling emergency softfork 🛡️

the final proof takes 50 seconds to run on my MacBook with Metal GPU acceleration, uses 12 GB of RAM during proving, with a final proof size of 1.7 MB

the proving code/statement is largely unoptimized, and it's possible to aggregate several proofs into a single smaller proof ⨻

an actual production deployment would likely use a smaller optimize circuit for this specific statement, this demo serves to demonstrate that such a proof is well within reach w/ today's hardware+software

to generate the proof I forked TinyGo to add a risc0 RISC-V ELF compilation target for TinyGo: https://t.co/eAMrgzh0x6

then I used some helper utilities and a C FFI wrapped risc0 library to create a generalized toolkit for TinyGo zk-STARK proofs: https://t.co/urVS6r1kA7

the final guest+host lives in the bip32-pq-zkp repo: https://t.co/7CoF0oL384

such a proof scheme is yet another tool in the post quantum toolkit for Bitcoin developers to prepare for an eventual PQ world 🤠

Mostly a reasonable take from @nvk, but misss a few important things IMO:

1) below threshold error rate only means that scaling may now be possible. He says it implies some kind of be exponential scaling but this is extremely misleading. The scaling that is now possible could be logarithmic, linear, or any other trajectory. For each bit so scaled, the improvement in computational power is indeed exponential, but if the scaling rate is logarithmic then the total computing power gained is linear.

2) he assumes that quantum is indeed coming. This is not a correct conclusion from the available evidence the evidence strongly suggests that quantum computing is either vastly more difficult in practice than the theories suggest, or entirely impossible due to some detail of the physical world that we do not yet understand.

3) he fails to mention the actual correct reason that bitcoin should indeed adopt alternate cryptosystems, which is that it is entirely likely that secp256k1 will someday fall to a classical attack, as many systems before it have.

Cryptographic systems defeated by classical cryptanalysis to date: too many to count.

Cryptographic systems defeated by quantum computers to date: 0

[Anthony Towns @ajtowns]

People like to make life hard for themselves. The real challenge is finding a PQ algorithm that works well at all: ie, is secure, is comprehensible, can sustain existing uses (HD derivations, multisig, lightning, silent payments, etc), and is still reasonably accessible (similar requirements to make transactions, or to run a node with similar global tx volume).

Without having solved those issues, talking instead about how best to confiscate coins from people who might not buy into your hypothetical plan if it ever exists seems pretty counter-productive at best.

[Blockstream Research @blksresearch]

Google Quantum AI released a paper exploring quantum threats to cryptocurrency, citing Blockstream Research work on post-quantum cryptography.

Here’s what we’re building to prepare Bitcoin for quantum computers, using @Liquid_BTC as a production-grade sidechain and prove upgrades before they are considered for Bitcoin mainnet.

@BetterCallMedhi En 2008 on parlait de 2020 pour l'ordi quantique utile (>> 3x5=15). Clairement en 2026 la menace sur la crypto demeure le mot de passe trop simple.
Cette fois au moins on a une prédiction sur 3 ans, c'est plus facile a avaler pour les investisseurs devenus trop impatients.

@giacomozucco @Mandrik There shouldn't be magic tricks 😅

[Skretcode @skretcode]

@giacomozucco @WalkerAmerica I knew someone that would first spend weeks convincing themselves of the veracity of a false statement before defending it. At which point they were not lying. It was mentally very challenging to work with them.

Pendant que les députés débattent de nouvelles taxes dans leur bulle de médiocrité, voici ce qui s’est passé ces derniers jours dans le monde :

- Amazon licencie 30 000 personnes à cause de l’intelligence artificielle.

- Google annonce une percée majeure dans la fusion nucléaire.

- Apple s’allie à SpaceX pour connecter ses iPhones aux satellites Starlink, annonçant peut-être la fin des opérateurs télécoms.

- OpenAI lance Atlas, une interface qui va rendre les agents intelligents accessibles à tous.

- Le premier robot humanoïde grand public, Neo, arrive sur le marché.

- Et Nvidia, première capitalisation du monde (que nombre de députés ne connaissent sans doute même pas), vient d’atteindre 5 000 milliards de dollars de valorisation et emploie désormais 80 % de millionnaires (n’en déplaise aux adeptes de la lutte des classes…).

Eh oui : pendant que le monde avance à la vitesse de la lumière, la France débat du montant des taxes et fait des dictées à l’Assemblée. Tous les députés ne sont bien sûr pas comme ça, mais une majorité semble vivre hors du temps. Ce n’est pas seulement un décalage, c’est une tragédie nationale.

Nous sommes en train de rater la plus grande révolution de l’histoire humaine.

Il est temps de sortir du métaverse fiscal et de revenir dans le monde réel.

[Skretcode @skretcode]

@giacomozucco @zndtoshi @stephanlivera Mistakes were made on the human side of change management. But given that the disagreements are ideological (it seems) rather than technical was there ever a chance for this change to happen in an orderly way?

@CatherineQui @BFMTV Qu'est-ce que c'est une entreprise innovante (pour le gars au fond de la classe 🫣)?

@gregory_nico It's probably bad for insect reproduction so needs to be restricted to day time and between 12:30PM and 1PM so as not to disturb nap time.
