Paradigm researcher proposes timestamp escape mechanism to protect early Bitcoin from quantum computing threats

Odaily reported that Paradigm researcher Dan Robinson proposed a new scheme called PACT (Prove Address Control with Timestamp), aimed at protecting long-dormant Bitcoin, including Satoshi Nakamoto's early addresses, from future quantum computing attacks.

The mechanism allows users to prove control over an address via a timestamp without transferring assets or exposing on-chain activity. Should a future quantum attack occur, assets can be recovered based on this proof within a quantum-resistant version of the Bitcoin network.

Compared to mandatory migration schemes such as BIP-361, PACT avoids the privacy exposure issues caused by proactively transferring assets, offering long-term holders a more flexible proactive protection path.
