Venture fund Paradigm has proposed a new design that would allow cryptocurrency holders to privately timestamp proof that they control vulnerable keys before quantum computers arrive, according to the proposal. The design is intended to create a possible rescue path if Bitcoin ever sunsets old addresses.
Proposal Concept
The design enables holders to generate private timestamped proof of key control without moving or exposing Bitcoin holdings. This approach is framed as a potential mitigation strategy against future quantum computing threats to Bitcoin’s security model.
Quantum Computing Threat Context
The proposal addresses the theoretical risk that quantum computers could compromise Bitcoin addresses that have not been spent (and therefore have not revealed their public keys on the blockchain). The timestamping mechanism would establish cryptographic proof of ownership prior to any such threat materializing.
