An Incomplete Guide to PBS - with Mike Neuder and Chris Hager
Uncommon Core 2.0
The Challenge of Monetizing Relays and the Need for Funding
This chapter discusses the significance of relays in the PBS process and the challenge of funding them, highlighting the proposal for an independent entity to provide grant funding for relay operation.
Hasu and Jon bring on Mike Neuder (Ethereum Foundation) and Chris Hager (Flashbots) to discuss the design philosophy of proposer-builder separation (PBS). They first dive into the past and present implementations of PBS, including MEV-Geth and MEV-Boost on Ethereum. Then they discuss the future of PBS - whether PBS should be enshrined, protocol-enforced proposer commitments (PEPC), PBS on L2s, how to prevent censorship, and more.
