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

Odaily星球日报讯 Paradigm researcher Dan Robinson has proposed a new solution called PACT (Verifiable Address Control Timestamp), designed to protect long-dormant Bitcoin, including Satoshi Nakamoto's early addresses, from future quantum computing attacks.

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

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