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

The Bitcoin community is considering a novel approach to mitigate the risks associated with quantum computing, which could potentially compromise the security of the network. Rather than imposing a pre-emptive freeze on vulnerable coins, the proposed system would wait for a quantum-capable attacker to demonstrate their capabilities and then trigger 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 attacker, serving as a public proof of the threat. The proposal includes a bounty system to incentivize the first entity to demonstrate a quantum attack, allowing contributors to withdraw their funds at any time. 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.
