Bitcoin Developers Propose Freezing Quantum-Vulnerable Coins in BIP-361

Bitcoin developers and researchers proposed BIP-361, a mechanism to freeze quantum-vulnerable coins as a private incentive for users to upgrade their security posture. The proposal, published Wednesday, aims to address the long-term threat posed by quantum computing to legacy Bitcoin addresses that lack quantum resistance.

According to the proposal authors, freezing lost or abandoned quantum-vulnerable coins would effectively increase the relative value of all other coins in circulation by reducing the total active supply. The mechanism is designed to encourage voluntary migration to quantum-resistant address formats before quantum computing capabilities advance to a point where they pose an active threat to the Bitcoin network.
