Incentives in Ethereum's Hybrid Casper Protocol
We present an overview ofhybrid Casper the Friendly Finality Gadget FFG: a Proof of Stake checkpointing protocol overlaid onto Ethereum's Proof of Work blockchain. We describe its core functionalities and reward scheme, and explore its properties. Our findings indicate that Casper's implemented incentives mechanism ensures liveness, while providing safety guarantees that improve over standard Proof of Work protocols. Based on a minimal impact implementation of the protocol as a smart contract on the blockchain, we discuss additional issues related to parametrisation, funding, throughput and network overhead and detect potential limitations.
