Quantum Threat to Bitcoin Sparks New Proposal to Protect Old Wallets

A new proposal from Paradigm aims to safeguard Bitcoin from future risks posed by quantum computers. Researcher Dan Robinson introduced PACTs, allowing holders of older wallets to prove ownership without moving funds. The system uses cryptographic timestamps today and quantum-resistant proofs later to unlock assets if vulnerable addresses are frozen. It could protect dormant holdings, including those linked to Satoshi Nakamoto, and offer an alternative to stricter proposals like BIP-361.
