Who Protects Bitcoin in the Quantum Era? New Alliance Exposes Deep Divisions Over Freezing Vulnerable Coins

A newly formed group of blockchain and security companies is trying to confront one of crypto’s most difficult long-term security questions: what happens if sufficiently powerful quantum computers eventually become capable of breaking the public-key cryptography used by Bitcoin, Ethereum and other major networks? The new Quantum Alliance brings together nine organizations across blockchain security, wallets and post-quantum cryptography, but early discussions already show that the technical problem may be easier to define than the governance problem required to solve it.
