Byzantine Fault Tolerance Consensus for Blockchains and Hyperledger Fabric

In this talk, we will briefly review the academic models for BFT protocols and analyze the commonly deployed BFT consensus protocols for blockchains such as Ethereum.

We will then compare several BFT protocols that could be used for Hyperledger Fabric and discuss the implementations details regarding BDLS that could be integrated into Hyperledger Fabric.

The talk will be based on the paper https://doi.org/10.1145/3538227 and on the implementations of BDLS at: https://github.com/hyperledger-labs/bdls

Bios of speakers:

Dr. Yongge Wang is a professor at UNC Charlotte. Dr. Wang has published extensively on research topics including algorithmic information theory, cryptography, and post-quantum security. Dr. Wang has proved several classical results in modern effective randomness research which are included as the fundamental theorems in most Algorithmic Information Theory graduate textbooks. Dr. Wang is the holder of three patents and the inventor of two IEEE 1363 standardized techniques (remote password based authentication protocol SRP5 and identity based authentication protocol WANG-KE). Dr. Wang is one of the designers for fundamental W3C and IETF XML security techniques such as XMLENC and XMLDSig syntax. These standards are the starting point for all XML related security techniques. Dr. Wang played important roles in developing research and education programs at UNC Charlotte. Recently, Dr. Wang has been working on fully homomorphic encryption, garbled computation techniques, and applied these techniques to achieve privacy preserving computation in the cloud. Dr. Wang has designed quantum resistant public key encryption techniques RLCE (http://quantumca.org) and developed the software package readily to be integrated into current Internet infrastructure. Dr. Wang has developed the 4-step UNCC patented BDLS Byzantine Fault Tolerance protocol for blockchains. Dr. Wang is currently an academic advisor for the Cryptic Labs http://crypticlabs.org that builds a unique community of illustrious cryptography and security advisors, researchers and innovative blockchain entrepreneurs who work on decentralize and distributed trust.

Ahmed Alsalih is a Sr. Software Engineer and Tech-Lead at AholdDelhaize. Also a Ph.D. student at UNCC, working under Dr. Wang's supervision. I have been in the tech industry since the beginning of the new millennium. I enjoy modernizing legacy systems and delivering software.
