Bitcoin Developers Propose 'Wait and React' Strategy to Counter Quantum Computing Threats
The Bitcoin community is considering a new 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 triggering a network-wide response. 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 accesses the funds, it will serve as public proof that the threat is real, and a network-wide freeze will be triggered to protect older wallets. The proposal also includes a bounty system, where users can contribute bitcoin to incentivize the first entity to demonstrate a quantum attack, rather than attempting to steal funds quietly. However, this approach assumes that the attacker will be motivated by the bounty rather than the potential for significant financial gain, which is a gamble that cuts against the network's usual emphasis on worst-case scenario planning.
