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 implementing a pre-emptive freeze on vulnerable coins, developers are proposing a 'wait and react' strategy that would only trigger a network-wide response if a quantum-capable attacker demonstrates their capabilities. This approach, outlined in a recent proposal by BitMEX Research, involves placing a small amount of bitcoin in a special address that can only be unlocked by a quantum-capable attacker, thereby serving as a public proof of the threat and automatically triggering a network-wide freeze. 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 relies on the assumption that the first entity capable of breaking Bitcoin's security would claim the bounty rather than attempting a large-scale theft, which may not be a reliable bet.
