The Red Belly Blockchain: Speed, Security, Scalability
To cope with blockchain inconsistencies, like double-spending, developers started building upon 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.

I will present the Red Belly Blockchain, a blockchain that does not use BFT consensus as a black box but rather solves the blockchain consensus problem, a variant of the classic consensus definition, 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 offers up to hundreds of thousands of UTXO transactions per second, perform reasonably well in 15 datacenters, on up to 1000 VMs, and under various attacks.

Habilitation from UPMC Sorbonne University.
