Bitcoin Developers Propose Alternative Strategy to Counter Quantum Computing Threat

The Bitcoin community is considering a novel approach to address the potential risks posed by quantum computing. Instead of enforcing a pre-set timeline for freezing vulnerable coins, the proposed 'wait and react' strategy relies on detecting the first quantum attack and responding accordingly. This plan, outlined by BitMEX Research, involves placing a small amount of bitcoin in a special address that can only be accessed by a quantum-capable attacker. If the attacker unlocks the address, it will serve as proof that the quantum threat is real, triggering a network-wide freeze of older wallets. The proposal also includes a bounty system, where users can contribute bitcoin to incentivize the first entity to demonstrate a quantum attack publicly, rather than secretly exploiting vulnerable wallets. This approach is designed to provide a more flexible and user-centric alternative to the previously proposed BIP-361, which would impose a fixed five-year timeline for phasing out vulnerable addresses. However, the success of this plan hinges on the assumption that the first entity capable of breaking Bitcoin's encryption will choose to claim the bounty instead of executing a large-scale theft. This assumption has sparked debate, as it contradicts the network's historical emphasis on preventing worst-case scenarios and minimizing protocol-level interventions.
