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 ...
