Binary byzantine agreement
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: WebA binary Byzantine agreement algorithm can be extended to produce a multivalued Byzantine agreement algorithm. The resulting multivalued algorithm is cheaper than …

WebIf SBA achieves byzantine agreement in time t SBA, given that less than half of the parties are corrupted, then HBA also achieves 1 2-consistency. HBA is guaranteed to terminate by time t out++ t SBA, where t out is a time-out parameter that can be chosen arbitrarily in HBA.In particular, if t SBA = t start+ O() (where t is the protocol starting time), then …
