Bitcoin: a developer proposes to trap future quantum hackers

Bitcoin Core developer Cory Fields has proposed a bond-and-secret-trap mechanism to protect vulnerable wallets from future quantum attacks, in which quantum attackers would forfeit their own staked bitcoin if they attempt to steal coins. The scheme is still theoretical and targets wallets whose public keys are already exposed, which quantum computers could eventually exploit to derive private keys. The proposal matters because it offers an economic deterrent rather than relying solely on migrating funds to quantum-resistant addresses. What to watch next is whether the bonding and trap design gains traction among Bitcoin Core contributors and moves from concept toward a formal improvement proposal.
