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

The Bitcoin community is considering a novel approach to addressing the potential threat of quantum computing to the network's security. Instead of imposing a predetermined freeze on vulnerable coins, the proposed 'canary' system would only trigger a network-wide restriction if a quantum-capable attacker demonstrates their capability on-chain. This 'wait and react' strategy relies on placing a small amount of bitcoin in a special address that can only be unlocked by a quantum-capable attacker, serving as public proof that the threat has materialized. The proposal includes a financial incentive, allowing users to contribute to a bounty that rewards the first entity to demonstrate a quantum attack publicly. However, this approach assumes that the attacker will claim the bounty rather than exploiting the vulnerability for personal gain, which raises concerns about the potential risks and consequences of such a strategy.
