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 pre-emptive freeze on vulnerable coins, the proposal involves waiting for an attacker to demonstrate their capabilities and then reacting accordingly. This 'wait and react' strategy relies on a 'canary' system, where a small amount of bitcoin is placed in a special address that can only be unlocked by a quantum-capable attacker. If the attacker succeeds in unlocking the address, it will trigger a network-wide freeze on older wallets, thereby protecting the network from potential theft. The proposal also includes a bounty system, where users can contribute bitcoin to reward the first entity to demonstrate a quantum attack, rather than attempting to exploit the vulnerability for personal gain. However, this approach assumes that the attacker will prioritize claiming the bounty over carrying out a large-scale theft, which may not necessarily be the case.
