S17 E23: Hunter Beast & Mark Karpelès on Bitcoin's Quantum Upgrade
- Quantum resistance for Bitcoin: CryptoQuick (Hunter Beast) from Surmount Systems is leading efforts to make Bitcoin quantum-resistant via BIP360. The team is raising funds and plans to accelerate development starting June 1st, working across multiple Bitcoin implementations (Core, LibreRelay, Knots, and others). - Timeline uncertainty: Quantum threat timelines remain unclear due to secretive government quantum computing programs. The NSA launched "Penetrating Hard Targets" in 2013 with $80M annual budgets; U.S. policy bans elliptic curve cryptography sales to government starting January 1, 2027. - P2PK coin vulnerability and solutions: Approximately 1.7 million dormant Bitcoin exist in exposed P2PK (pay-to-public-key) outputs across 34,000 keys. Proposed solutions include throughput restrictions (BIP360 Hourglass V2 allows ~144 BTC/day movement over 32 years) rather than burning Satoshi's coins, balancing property rights with theft prevention. - Cryptographic trade-offs: Switching to post-quantum cryptography (hash-based signatures like SLHDSA) will require sacrificing conveniences like HD wallet derivation (BIP32) and extended public keys (XPUB). Solutions like threshold signatures (TSS) and new wallet designs are being explored. - Avoiding scope creep: Quantum upgrades should remain focused on security and not be bundled with unrelated functionality upgrades like Simplicity smart contracts. BIP54 (Great Consensus Cleanup) and incremental, evidence-based activation through BIP process preferred over drastic hard forks. - Mark Arpelès on MT. Gox recovery: Most repayments completed; remaining customers may receive new airdrop assets from upcoming BCH fork if the trustee determines market value exists. Lessons include importance of transparency, HD wallets, and avoiding key reuse—technologies unavailable during MT. Gox era.
BITCOIN CORE HAS A SERIOUS PROBLEM
- Vegas trip recap: Hosts discussed their Bitcoin conference attendance, Vegas meetup with fans, and conversations with influential figures in the Bitcoin community. They noted unexpectedly high recognition and influence despite self-described "random" podcast content. - Bitcoin Astrology panel: First-ever Bitcoin Astrology panel at the conference, featuring high female attendance and discussion of 2026 as a significant year astrologically. Hosts plan to release the recording. - Quantum computing debate: Main stage quantum panel featured Alex Thorn, Root & Code, James O'Byrne, Hunter Beast, and Alex Pruden. Discussed grifters in quantum space (Project 11 example), the importance of engaging respectfully with technical critics, and the hypothetical doomsday scenario of quantum breaking elliptic curve cryptography while providing no other useful applications. - Hodlinaut's Bitcoin Core article: Second piece in a series examining informal governance and "soft power" within Bitcoin Core. Claims promotion and sidelining decisions are based on personality and likability rather than strict meritocracy (examples: Luke Jr. disfavor, Gloria Zhao rapid rise). Hosts discuss whether this is problematic or simply normal organizational behavior. - AI adoption among developers: Smart developers extensively using AI in their workflows. Hosts noted that AI pivot is becoming common at Bitcoin conferences, with projects rebranding around AI and sovereignty themes. - Paul Sztorc's e-cash fork: Discussion of Paul's potential drivechain fork and risk of mission creep as supporters push additional features. Urged focus on core drivechain testing rather than feature snowballing.
WILL QUANTUM BREAK BITCOIN? W/ Hunter Beast
- Quantum computers pose a potential long-term threat to Bitcoin's ECDSA signature cryptography, though the timeline remains uncertain (5–20+ years away). - BIP 360 proposes a new soft-fork address type (BC1R) using post-quantum cryptography with three different signature algorithms to hedge against unknown weaknesses in any single approach. - Vulnerable Bitcoin address types include pay-to-public-key (e.g., Satoshi's coins), reused addresses, and taproot addresses; segwit addresses remain safe as long as they are never reused. - When users spend from any address, the public key is revealed in the transaction mempool, creating a window for quantum attackers to derive the private key before the transaction is mined or reorgs occur. - The US government (CNSA 2.0 roadmap) has mandated moving away from elliptic curve cryptography in government systems by 2030–2035, signaling institutional concern about quantum threats. - Implementing post-quantum cryptography in Bitcoin would increase block verification time (2–4x slower in most cases) and potentially reduce throughput to 1,000–3,000 transactions per block, but introduces design flexibility for security-conscious users.
