Bitcoin Developers Propose 'Wait and React' Strategy to Counter Quantum 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 preemptive 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 realized. The proposal includes a bounty system, where users can contribute bitcoin to reward the first entity to demonstrate a quantum attack publicly, rather than exploiting the vulnerability for personal gain. However, this strategy relies on the assumption that the first entity capable of breaking Bitcoin's security will claim the bounty instead of executing a large-scale theft. This assumption has sparked debate, as it contradicts the network's historical approach to security and the principle of minimizing protocol-level interventions.
