Odaily News Bitcoin developer Agustin Cruz proposed a BIP draft called "Quantum Resistant Address Migration Protocol" (QRAMP), which plans to migrate BTC from old wallets encrypted with ECDSA to wallets protected by post-quantum cryptography through a hard fork. The proposal sets a migration cutoff block height, at which time nodes will reject transactions without migrating addresses. This move is intended to address potential quantum computing threats. Although there is no direct risk at present, Microsoft's recent release of the quantum processor Majorana 1 has caused concern. (CoinDesk)
