early draft & work in progress This doc outlines an idea for mev-boost to connect directly to a network of SGX-based block builders, obviating the need for relays as intermediaries. Such a setup could: remove the need for relays as trusted intermediaries produce higher value blocks for proposers, because builders have more time building them (don't need to submit to a relay up-front) pave the way to enclave-based privacy-preserving orderflow sharing between builders pave the way for PEPC by allowing for arbitrary commitmentsfrom builders to proposers

MEV-Boost Release of mev-boost v1.4.0 with notable feature of setting a minimum bid value Proposal to replace types from go-boost-utils with those from Attestant (WIP PR) Updated bug-bounty amounts Preparations for Capella & EIP-4844 changes Ongoing research on inclusion lists / crLists / partial block auctions / proposer-build pre/suffixes See also the mev-boost status update from 2022-11-03 Relay Ecosystem

Quick summary of what's currently happening in and around MEV-Boost, as of Nov. 3, 2022. Upcoming release of mev-boost v1.4.0 Notably includes the ability to set a minimum bid value, under which mev-boost won't provide a bid to the beacon node. Several minor improvements. More details at https://github.com/flashbots/mev-boost/issues/377 Updated getValidator relay data API

Ideas, questions and technical approach to implementing inclusion lists. Note: This document assumes the inclusion list functionality being implemented by both beacon node and mev-boost. It might be worth investigating whether this can be done exclusively in mev-boost, without changes to the BN.
