The job consensus layer of the IC is to order transaction requests so that all replicas in a subnet will process transaction requests in the same order. There are many protocols in the literature for this problem. The IC uses a new consensus protocol, which is described here at a high level. For more details, see the paper https://eprint.iacr.org/2021/1330 (in particular, Protocol ICC1 in that paper).
The IC consensus protocol is design to be
- extremely simple, and
- robust (performance degrades gracefully when some replicas are malicious).
