A proof of possession scheme uses a separate public key validation step, called a proof of possession, to defend against rogue key attacks. This enables an optimization to aggregate signature verification for the case that all signatures are on the same message.
type proof = Bytes.tEquivalent to core_sign with the DST given in the specification, section 4.2.3
Equivalent to core_verify with the DST given in the specification section 4.2.3
pop_proof sk implements the algorithm described in section 3.3.2
pop_verify pk proof implements the algorithm described in section 3.3.3
aggregate_verify pks msg aggregated_signature performs a aggregate signature verification. It supposes the same message msg has been signed. It implements the FastAggregateVerify algorithm specified in section 3.3.4
