Consensus protocols are used by nodes to make consistent decisions in a distributed network. However, consensus protocols for public blockchains should satisfy other requirements, by virtue of the protocol being open. For example, they need to be incentivized, in that people will be incentivized to run consensus forming nodes in the first place, and in that following the protocol should be an equilibrium for consensus forming nodes.The CBC Casper family of consensus protocols has been designed to fit design criteria necessary for secure public blockchains. In this talk, we will explore the design goals and methodology used in CBC Casper research: economically motivated properties of the consensus protocol, the correct-by-construction approach to protocol specification, and the resulting rapid iteration.
