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

Odaily reports that Paradigm researcher Dan Robinson has proposed a new scheme called PACT (Prove Address Control Timestamp), designed to protect long-dormant Bitcoin, including early Satoshi addresses, from future quantum computing attacks.

This mechanism allows users to prove their control over an address through a timestamp without needing to transfer assets or expose on-chain activity. In the event of a future quantum attack, assets can be recovered on a quantum-resistant version of the Bitcoin network based on this proof.

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