Binary byzantine agreement
WebOct 23, 2024 · In the binary Byzantine Agreement protocol, parties decide whether or not to add a particular block to the chain. To extend this to deciding which block to add to the chain, if any, parties will first attempt to decide a block to vote on during the binary Byzantine Agreement execution. WebPluggable Binary Byzantine Agreement. The consensus described below uses an Asynchronous Binary Byzantine Agreement (ABBA) protocol. We currently use a variant of ABBA derived from Mostefaoui et al. Any other ABBA protocol P can be used, as long as it satisfies the following properties:
