Order-fairness for byzantine consensus
WebTo reach agreement on the order in which data blocks appear in the chain, blockchains resort to the fundamental problem of consensus. Consensus is one of the most studied problems in distributed computing. Mainstream consensus implementations follow the classical leader-based approach [ 26,43], where a single process is ...

PoA has been widely adopted by communities and industries due to its better performance and faster finality. In this paper, we explore the unfairness issue existing in the current PoA implementations.
WebByzantine ordered consensus protocol is used to tolerate Byzantine faults in ordering manipulation. To achieve it, we believe Byzantine ordered consensus protocol should have two essential properties, free will and fairness. Free Will. Free will is a concept proposed by Zhang et al. [12]. Briefly, it means no one could manipulate the total ...
