Optimal algorithms for byzantine agreement
WebAug 17, 2024 · Our algorithms operate in a very strong fault model: we require self-stabilisation, i.e., the initial state of the system may be arbitrary, and there can be up to f< n/3 ongoing Byzantine faults, i.e., nodes that deviate from the protocol in an arbitrary manner. WebThus far, however, reaching Byzantine agreement has required either many rounds of communication (i.e., messages had to be sent back and forth a number of times that grew …

WebSuppose that there were an algorithm that solved Byzantine agreement with n=3f processes. Group the processes into groups of size f, and let each of the n=3 processes simulate one group (giving everybody the same input). Then we get a protocol for n=3 and f=1, an impossibility. 1.3.
