To improve peak blockchain performance, researchers and developers started building upon the Byzantine fault-tolerant (BFT) consensus. At first it seems reasonable because consensus can be effective at totally ordering transactions into a chain, however, it is notoriously difficult to scale. In this talk, Vincent Gramoli will present the Red Belly Blockchain, a blockchain that does not use BFT consensus as a black box, but rather solves a new variant of the classic consensus problem that was recently defined for blockchains. Our experimental settings range from hundreds of nodes in a single datacenter to a thousand of nodes on 4 continents under various failure models. Our results show that the Red Belly Blockchain performs well.
