Studies from Toyohashi University of Technology Further Understanding of Information Technology

March 4, 2014



By a News Reporter-Staff News Editor at Information Technology Newsweekly -- Current study results on Information Technology have been published. According to news reporting from Toyohashi, Japan, by VerticalNews journalists, research stated, "We propose a new method that accelerates asynchronous Byzantine Fault Tolerant (BFT) protocols designed on the principle of state machine replication. State machine replication protocols ensure consistency among replicas by applying operations in the same order to all of them."

The news correspondents obtained a quote from the research from the Toyohashi University of Technology, "A naive way to determine the application order of the operations is to repeatedly execute the BFT consensus to determine the next executed operation, but this may introduce inefficiency caused by waiting for the completion of the previous execution of the consensus protocol. To reduce this inefficiency, our method allows parallel execution of the consensuses while keeping consistency of the consensus results at the replicas. In this paper, we also prove the correctness of our method and experimentally compare it with the existing method in terms of latency and throughput."

According to the news reporters, the research concluded: "The evaluation results show that our method makes a BFT protocol three or four times faster than the existing one when some machines or message transmissions are delayed."
