Understanding the Quantum Attack Vectors | Bitcoin 2026

Will quantum computers break Bitcoin? At the Bitcoin 2026 Conference Open Source stage, BIP-360 co-author and Bitcoin Rails host Isabel Foxen Duke leads the most serious quantum debate of the year. Joined by Pauli Group quantum scientist Pierre-Luc Dallaire-Demers, Chaincode Labs researcher Clara Shikhelman, and Bitcoin developer Brandon Black of Rearden Code, the panel argues over timelines, post-quantum cryptography trade-offs, and what to do with Satoshi's coins. They cover lattice cryptography, hash-based Lamport signatures, the "hourglass" rate-limit proposal, and why migrating Bitcoin to post-quantum signatures may be the hardest consensus build in Bitcoin's history.
