Project Eleven has introduced a post-quantum proof technology designed to help users prove ownership of Bitcoin wallets after quantum computers can derive private keys and generate valid signatures. According to Odaily, Project Eleven CEO Alex Pruden said the system uses a wallet key derivation path to let users prove control without revealing the parent key, helping distinguish legitimate owners from attackers.
The prototype was developed with Jim Posen, a main maintainer of the open-source Binius zero-knowledge proof system, and is based on the “signature lifting” technique proposed by Alon Sattath and Robert Wyborski. Project Eleven said the prototype has not been audited and would require blockchain protocol support before use. It is intended mainly for users who miss a future migration to quantum-resistant addresses.
