Bitcoin Core developer Cory Fields published a proposal to the Bitcoin Development mailing list on November 4 that approaches the quantum threat from the incentive side rather than from the cryptography side: after a quantum break, anyone spending an old bitcoin output would first have to lock up bitcoin of their own, and could lose that collateral to whoever proves a better claim to the coins. The post, Quantum Landmines and Vulnerable Coin Auctions , sets out three mechanisms: Quantum Landmines, Staked Auction and Sats Auction. None of them makes bitcoin quantum-resistant.
