Order-fairness for byzantine consensus
WebTo rectify this problem, we propose a third consensus property: transaction order-fairness. We initiate the first formal investigation of order-fairness and explain its fundamental importance. We provide several natural definitions for order-fairness and analyze the assumptions necessary to realize them. Websimplified the ordering phase, but they are limited on fairness that the adversary can manipulate the ordering via timestamps of transactions. In this paper, we propose a …

WebTo reach agreement on the order in which data blocks appear in the chain, blockchains resort to the fundamental problem of consensus.

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 ...
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.
