Detailed Description

template<typename G1, typename HashRegNon, typename HashSig = Blake2sHasher>
struct bb::crypto::schnorr_multisig< G1, HashRegNon, HashSig >::MultiSigPublicKey

MultiSigPublicKey wraps a signer's public key g1::affine_element along with a proof of posession: a signature whose message is the public key, signed by the corresponding private key.

This is to prevent attacks where an attacker presents a key that they do not know the secret to (e.g. the attacker public key is a linear combination of other public keys)
