struct PartialSignature

Overview

Each signer produces one P256K.Schnorr.PartialSignature per signing session. The partial signature does not verify as a standalone signature; it only becomes valid after all partial signatures are aggregated into a P256K.MuSig.AggregateSignature.

Internally the signature bytes are the opaque 36-byte secp256k1_musig_partial_sig struct body. The wire format is 32 bytes, produced by secp256k1_musig_partial_sig_serialize and consumed by secp256k1_musig_partial_sig_parse. See Vendor/secp256k1-zkp/include/secp256k1_musig.h for the upstream declarations.
