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

The Bitcoin community is considering a novel approach to address the potential threat of quantum computing to the network's security. Instead of imposing a pre-emptive freeze on vulnerable coins, the proposal involves a 'wait and react' strategy that relies on a canary system to detect and respond to a quantum attack. This system would involve placing a small amount of bitcoin in a special address that can only be unlocked by a quantum-capable attacker, triggering a network-wide freeze of older wallets if the address is compromised. The proposal also includes a financial incentive, where users can 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.
