IntroductionWe've implemented a new approach to Schnorr signatures using Fully Homomorphic Encryption (FHE), allowing cryptographic signing while maintaining complete encryption of the private key throughout the entire process. This implementation leverages Zama.ai's TFHE-rs library, which enables computation on encrypted data. Want to explore the implementation? Check out our code on GitHub.The ChallengeThe traditional cryptographic signing process requires access to unencrypted pr...
