Remove mention of Aggregate Signatures. Formally, an aggregate signature scheme would require an aggregated signature on messages \(m_1, .... m_n\) to be of the same size as a signature on a single message. We used some slack in [FOS19] to bring Schnorr and BLS under the same framework but Schnorr/MuSig are definitely not know for its aggregation capabilities. MuSig is a multisignature, which is very different -- also they could be seen as part of the big umbrella term of "Schnorr Signatures"

@tromp @yeastplume Any thoughts on the above feedback? To my understanding grin does aggregate signatures since the "aggregated signature" of n signatures is of the same length of a single signature, but this is going into the realm of cryptographic definitions which is not my cup of tea. |
