Piers joins us on Base Layer to give a full rundown on Radix and Cerberus, a sharded Byzantine fault-tolerant (BFT) solution to the state machine replication (SMR) problem. While classical SMR protocols ensure global ordering of commands, Cerberus introducesa partial ordering regime that enables a novel state sharding approach. With this approach, the consensus process for commands may be massively and safely parallelized across many nodes while retaining optimistic responsiveness and linear message complexity. Cerberus is designed as a suitable core for Radix, a distributed ledger technology (DLT) platform intended for a variety of deployments including global-scale decentralized public networks.
