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

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, developers are proposing a 'wait and react' strategy. This approach involves 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 threat is demonstrated. The proposal includes a bounty system to incentivize the first entity to demonstrate a quantum attack, rather than exploiting the vulnerability for personal gain. However, this strategy relies on the assumption that the attacker will choose to claim the bounty rather than perpetrate a large-scale theft. This assumption has sparked debate, as it contradicts the network's historical emphasis on preventing worst-case scenarios. The proposed 'canary' system aims to balance the need for security with the risk of disrupting users prematurely, but its success hinges on the attacker's decision to cooperate.
