Paradigm partners propose the PACTs mechanism to provide a protection pathway for quantum-vulnerable Bitcoin addresses
Mars Finance News: Paradigm general partner Dan Robinson proposed a “Proven Address Control Timestamp” (PACTs) mechanism, aiming to provide a protection path for Bitcoin addresses under potential threats from quantum computing. The scheme enables coin holders to generate address control proofs via BIP-322, combined with on-chain commitments generated using random salt values, and uses OpenTimestamps to complete time anchoring, thereby establishing ownership proofs without disclosing wallet information. If, in the future, soft forks freeze quantum-vulnerable addresses, users can submit STARK zero-knowledge proofs when spending to unlock assets. This mechanism also provides a potential recovery path for wallets derived from BIP-32, but its implementation still relies on Bitcoin introducing STARK verification capabilities and reaching community consensus.
