Babbitt reported that on August 24th, the US local time, "2019 than the original global developer conference" officially opened in San Francisco, USA. Wang Wei, inventor of the BBFT consensus algorithm, said in his speech that the reason for studying the new consensus algorithm is that the commonly used PBFT algorithm cannot be expanded, and all the verifications in FBFT must pass the key leader (centralized security risk). In contrast, BBFT is Configurable, Adaptive, Scalable, and Heterogeneous. At the same time, BBFT also supports BLS private key aggregation and network partitioning (Parition). Finally, Wang Wei said that under the BBFT algorithm, the blockchain verified the number of transactions per second to 20,000, the transaction confirmation time was only 0.6 seconds, and the probability of forking was only 0.27%.
