Module bls_multi_signature

BLST Multi-signature module

Structs

ProofOfPossession

MultiSig proof of possession, which contains two elements from G1. However, the two elements have different types: k1 is represented as a BlstSig as it has the same structure, and this facilitates its verification. On the other hand, k2 is a G1 point, as it does not share structure with the BLS signature, and we need to have an ad-hoc verification mechanism.

Signature

MultiSig signature, which is a wrapper over the BlstSig type.

SigningKey

MultiSig secret key, which is a wrapper over the BlstSk type from the blst library.

VerificationKey

MultiSig verification key, which is a wrapper over the BlstVk (element in G2) from the blst library.

VerificationKeyPoP

MultiSig public key, contains the verification key and the proof of possession.
