Order-fairness for byzantine consensus
WebIn this paper, we formulate a new property for byzantine consensus which we call order-fairness. Intuitively, order-fairness denotes the notion that if a large number of nodes receive a transaction tx 1 before another one tx 2, then this should somehow be re ected in the nal ordering. Importance of fair transaction ordering. WebUntil now, computer-aided proofs of the liveness of byzantine consensus algorithms assumed synchrony to reason in lock steps or the error-prone manual intervention of experts in the proof checker, but could not be automated through model checking. We propose a compositional approach to verify a consensus algorithm, for any number n of processes …
