Anchors

Anchors.

An anchor is a leader certificate that is committed to the blockchain, either directly, by receiving enough votes (see elections), or because it is reachable via a path from one receiving enough votes to a previously committed anchor or to round 0. A leader certificate is a certificate in a DAG that is authored by the leader of the certificate's round.

Here we define operations related to anchors.

Collect-all-anchors
