PoS-CoPOR: Proof-Of-Stake Consensus Protocol with Native Onion Routing Providing Scalability and DoS-Resistance

Proof-of-Stake PoS consensus protocols often face a trade-off between performance and security. Protocols that pre-elect leaders for subsequent rounds are vulnerable to Denial-of-Service DoS attacks, which can disrupt the network and compromise liveness. In this work, we present PoS-CoPOR, a...

SoK: Current State of Ethereum'S Enshrined Proposer Builder Separation

Initially introduced to Ethereum via Flashbots' MEV-boost, Proposer-Builder Separation allows proposers to auction off blockspace to a market of transaction orderers, known as builders. PBS is currently available to validators through the aforementioned MEV-boost, but its unregulated and...
