WebThis paper describes a method for extending a binary Byzantine agreement algorithm to reach agreement on values from an arbitrary domain V. Any binary algorithm that does not require a distinguished transmitter process may be used. Two rounds are prepended to the binary algorithm. In the first round, each process sends every other process its ... WebAn Asynchronous Binary Byzantine Agreement is then executed for each block proposal to reach consensus on whether it is data-available. If multiple block proposals are known to be data-available, a BLS-based common coin is used to select the winning proposal that is committed to the chain.
