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

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 proposed 'wait and react' strategy would only trigger a network-wide response if a quantum-capable attacker demonstrates their capabilities. This approach is based 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, serving as a public proof of the threat. The proposal includes a bounty system to incentivize the first entity to demonstrate a quantum attack, rather than attempting to exploit the vulnerability for personal gain. However, this approach relies on the assumption that the first entity to demonstrate a quantum attack will claim the bounty rather than attempting to steal a large amount of bitcoin, which may not be a reliable bet. The proposal is designed to provide an alternative to a fixed five-year timeline for implementing security measures, which has been criticized for being authoritarian and confiscatory. The 'wait and react' strategy aims to balance the need for security with the need to preserve the decentralized and permissionless nature of the Bitcoin network.
