Multi-Party Computation (MPC) has revolutionized Ed25519 cryptography by enabling distributed private key operations without single points of failure.
This distributed MPC approach eliminates the fundamental vulnerability of single private keys while preserving the signature verification simplicity that makes Ed25519 attractive for production systems.
MPC enables n parties to jointly compute functions over private inputs without revealing anything beyond the output.
