Woofun AI reports that Project Eleven has introduced a post-quantum proof technology enabling users to demonstrate Bitcoin wallet ownership after quantum computers can derive private keys. CEO Alex Pruden explained that the system leverages key derivation paths to verify control without revealing the parent key, thereby distinguishing legitimate owners from attackers.

Developed with Jim Posen of the Binius zero-knowledge proof system, the solution utilizes the "signature lifting" technique by Alon Sattath and Robert Wyborski. Project Eleven stated that the unaudited prototype requires blockchain protocol support for deployment and primarily serves users who miss the migration window to quantum-resistant addresses.
