Project Eleven Unveils Quantum-Resistant Wallet Recovery Solution

Project Eleven has developed a cryptographic technique to protect Bitcoin owners from quantum attacks. The solution uses a wallet's key derivation path to verify control of the master key without revealing it to the public. This is crucial as estimates suggest that nearly 7 million Bitcoins could be vulnerable to quantum attacks if users do not migrate to secure addresses by Q-Day.

The project was funded and implemented on Binius, a zero-knowledge proof system designed to accelerate cryptographic hash operations. According to technical documentation, the development is based on the concept of 'signature lifting' originally proposed by security researchers Alon Sattath and Robert Wyborski under the supervision of developer Jim Posen.

The risk of delays in transitioning to post-quantum cryptography remains a concern for the private sector. In June 2026, the Coinbase quantum advisory council warned that nearly 7 million Bitcoins could be exposed if end-users do not make the corresponding migration to secure addresses.
