FROST (Flexible Round-Optimized Schnorr Threshold)
Cryptography● Common
A threshold signature scheme allowing t-of-n signing where any t participants can produce a valid Schnorr signature without revealing the combined private key. Unlike MuSig which requires all parties, FROST enables flexible quorums. The resulting signature is indistinguishable from single-sig Taproot spends.
Technical Notes
Uses Shamir's Secret Sharing for key generation. Signing requires a preprocessing phase generating nonce shares, then a single signing round. ChillDKG is an emerging standard for FROST Distributed Key Generation. Compatible with BIP-340 Schnorr signatures.
