Abstract:
A Byzantine fault tolerance method in a blockchain platform, which is related to an audit transaction analysis method for analyzing operation of a blockchain ordering service, may comprise: determining, through an audit transaction analysis submitted by each blockchain node included in at least one received block, a consensus level of the received block; and detecting a malfunction and a malicious attack of an ordering service on the basis of a consensus level update delay time and an error analysis of an audit transaction analysis process in the blockchain node.
