What is Casper (CSPR)

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

• Cartelization / censorship
• Equivocation
• Reversion
• Invalidity

3. Abstract and Future Proof

• Ready-built for sharding
• Built with upgradability in-mind
• Flexible payment model

4. Increases Decentralization

• Can have Min/Max staking amounts
• Can raise participation requirements with minimal overhead increase
• Allows people with limited hardware (within reason) to participate in securing the network

5.Increases Energy Efficiency

• Most processing power is tasked toward useful work of processing transactions

6. Increases Security

• An attack cannot revert a finalized block
