What is Casper

CBC Casper is a family of “correct-by-construction” consensus protocols that share the same proof of asynchronous, Byzantine-fault-tolerant consensus safety. We describe this family of protocols by defining their protocol states and protocol state transitions, and then we provide a proof of Byzantine-fault-tolerant consensus safety for the entire Minimal CBC Casper family of protocols. We give examples of members of this family of protocols, including a binary consensus protocol. “Casper the Friendly Ghost”, a blockchain consensus protocol, and a sharded blockchain consensus protocol. Each of these examples is “correct-byconstruction” because the way they are defined guarantees that they are part of this family of protocols, and therefore satisfy the consensus safety theorem.

Key Features of CBC Casper:

1. Proposed by Vlad Zamfir of the Ethereum Foundation to address scalability and energy consumption issues.

2. Punishes Key Bad Behavior

3. Abstract and Future Proof

4. Increases Decentralization

5.Increases Energy Efficiency

6. Increases Security
