Bitcoin Developers Propose 'Wait and React' Strategy to Counter Quantum Computing Threats

The Bitcoin community is considering a novel approach to addressing the potential risks posed by quantum computing: delaying the implementation of security measures until a real threat is detected. However, this plan relies on the assumption that the first entity to demonstrate a quantum attack will do so in exchange for a reward, rather than exploiting the vulnerability for financial gain. A recent proposal by BitMEX Research outlines a 'canary' system, where a small amount of bitcoin is placed in a special address that can only be accessed by a quantum-capable attacker, triggering a network-wide restriction on older wallets if the funds are spent. This approach is designed to replace earlier plans to impose a pre-scheduled freeze on vulnerable wallets, regardless of whether a quantum threat materializes. The proposal also includes a financial incentive, allowing users to contribute to a bounty that rewards the first entity to demonstrate a quantum attack, and introduces a 'safety window' to make stealth attacks more difficult. Critics argue that this approach rests on an uncertain bet that the first entity capable of breaking Bitcoin's security will claim the bounty rather than executing a large-scale theft, which could have significant implications for the network's security and user trust.
