nice, I was originally puzzled re why do we compare signatures as they can be malleable, but this is for serde tests which makes sense.

We usually refer to it as auth_sign_info, ideally we should pick a consistent name, either auth or quorum

Maybe AuthQuorumSignInfo? We already have AuthSignInfo to represent a single authority signature

Thanks, the readability problem is still remaining (cause while you read this you expect to see an AuthoritySignInfo), what about renaming auth_sign_info to quorum_sign_info and keep your previous QuorumSignInfo?

auth_sign_info can be one of EmptySignInfo, AuthoritySignInfo and AuthorityQuorumSignInfo.
So I don't think we want to rename it to quorum_sign_info.

Hm.. ok, let's leave it unchanged for now, we might consider renaming it to the more generic sign_info later, but don't change yet, auth_sign_info works for now.

The same structure also contains transaction signature (tx_signature). So this is named auth_sign_info to emphasize that the signature is from authority side instead of from transaction signer.
But yeah open to better names!

Also, we should note that certified txs can carry more than quorum sigs (every authority might in theory sign), and wondering if we should put a comment here to clarify it (unless quorum implies quorum+)

CertifiedTransactionis also just a Transaction that's signed by authorities, making it very similar to SignedTransaction.This PR introduces
QuorumSignInfoas a new authority signature trait type, and defineCertifiedTransactionusing it.This also allows us to unify some of the code, for example, the
Transactiontype now also has a cached digest field.
