Project Eleven proposes quantum-resistant method for proving BTC wallet ownership

Quantum-resistance firm Project Eleven has proposed a new technology to prove ownership of a Bitcoin wallet even if quantum computers render existing digital signatures obsolete, Decrypt reported. The method uses a wallet's key derivation path to demonstrate possession of a higher-level key without exposing the private key itself. The company explained that this is possible because the original key or seed phrase used to create a wallet cannot be replicated. However, the technology is still in its early stages and would require support at the Bitcoin protocol level for implementation. The proposal comes as the cryptocurrency industry has begun to address the growing number of research reports highlighting the potential security threats posed by quantum computing.
