Schnorr Signature
Cryptography● Common
A digital signature scheme activated with Taproot (BIP-340). Offers smaller signatures (64 bytes fixed), native key aggregation (MuSig2), and batch verification efficiency. Simpler security proofs than ECDSA. Enables advanced protocols like PTLCs.
Technical Notes
Signature: (R, s) where s = k + e·x, e = hash(R||P||m). Linear: enables key aggregation without complex MPC. MuSig2: n-of-n looks like single-sig. FROST: t-of-n threshold. BIP-340 uses x-only pubkeys (32 bytes). Replaces ECDSA for Taproot spends.
