Certificates
Certificates.
Validators generate and exchange certificates,
which consist of proposals with endorsing signatures.
Certificates are the vertices of the DAG,
in the Narwhal part of AleoBFT.
Beside defining certificates,
we also introduce operations on (sets of) certificates,
particularly to retrieve certificates from sets
according to author and/or round criteria.
Since DAGs are represented as sets in validator states,
these operations are usable (and in fact mainly used) on DAGs.
