Flashbots has been critical to leveling the MEV playing field on Proof-of-Work (PoW) Ethereum (eth1), and aims to bring the same benefits to Proof-of-Stake (PoS) Ethereum (eth2). The adoption of Flashbots involves two distinct parties, block producers, and MEV searchers. In Ethereum, over 90% of miners have adopted Flashbots; however, as we approach eth2 and the transition to PoS, adoption will reset to 0. As such, for the health of the Ethereum ecosystem, it is imperative that validators also adopt an MEV solution for Ethereum post-merge. To assist in this adoption, we are pleased to announce the Flashbots Eth2 Working Group.
This document outlines the design for a marketplace for block construction (often referred to as block proposer / block builder separation or PBS) compatible with the upcoming Ethereum merge fork. This trust based solution closely resembles the current Flashbots auction design with modifications to enable solo staker participation without introducing changes to Ethereum consensus. This solution aims to bridge the gap to a permissionless PBS design which should be strongly considered for the cleanup fork in order to improve decentralization.
Ethereum will soon transition from a Proof of Work (PoW) to a Proof of Stake (PoS) consensus protocol. This transition has been worked on for years and is happening in multiple steps. The first step in December 2020 consisted in launching the beacon chain. It is now live, and, at the time of writing, has more than 160k validators or an equivalent of ~5m ETH staked on it.
