Bitcoin's quantum debate splits as Adam Back pushes optional upgrades over forced freeze

Blockstream CEO Adam Back is advocating for the development of optional, quantum-resistant upgrades for Bitcoin, arguing that preparation should be gradual rather than reactionary. His position emerges amid a growing debate regarding the threat quantum computing poses to Bitcoin's cryptography. This stands in contrast to a proposal by Jameson Lopp, known as BIP-361, which suggests a mandatory five-year timeline to phase out vulnerable addresses by freezing non-migrated coins. While Back relies on Bitcoin's historical ability to reach consensus quickly during emergencies, proponents of the freeze argue that a scheduled migration is necessary to prevent a disorderly collapse should a quantum breakthrough occur.
