Paradigm Partner Proposes PACTs Mechanism to Provide Protection Path for Quantum-Vulnerable Bitcoin Addresses

Odaily Planet Daily News, Paradigm General Partner Dan Robinson has proposed a mechanism called "Provable Address Control Timestamps" (PACTs), aimed at providing a protection path for Bitcoin addresses under the potential threat of quantum computing. This solution allows holders to generate proof of address control via BIP-322, create an on-chain commitment combined with a random salt value, and utilize OpenTimestamps for time anchoring, thereby establishing proof of ownership without revealing wallet information. If quantum-vulnerable addresses are frozen through a soft fork in the future, users can submit a STARK zero-knowledge proof when spending to unlock assets. This mechanism also offers a potential recovery path for wallets based on BIP-32 derivation, but its implementation still relies on Bitcoin introducing STARK verification capabilities and gaining community consensus.
