Project Eleven maintains that a newly devised post‑quantum cryptographic proof could permit Bitcoin users to regain access to their wallets once the feared “Q‑Day” arrives, by establishing indisputable proof of ownership.
The proof is built on lattice‑based constructions that are designed to withstand quantum‑level attacks, allowing a wallet holder to generate a verifiable credential without ever exposing the underlying private key.
According to analyses of open‑source research, the technique would let an owner demonstrate control of an address through a one‑time computational puzzle that only the legitimate possessor can solve, thus enabling recovery even if the original seed phrase has been lost or compromised.
This forward‑looking solution addresses the potential vulnerability of current elliptic‑curve signatures to future quantum computers, ensuring that Bitcoin participants can maintain uninterrupted access to their funds.
