Flashbots met with Ethereum ecosystem partners and contributors of MEV-Boost during DevCon Bogotá to align on decentralizing proposer/builder separation as a community. Below is a summary of discussed priorities, updates since Devcon, and next steps we’ll continue to collaborate toward. _Please comment with any additional updates or information!_
## Summary of Priorities
- [Inclusion list / partial block auction implementation](https://hackmd.io/5rrA0KfBTFS7uvIEg41Lag)
- [Block scoring and payment proofs](https://collective.flashbots.net/t/block-scoring-for-mev-boost-relays/202/16)
- Local and remote block comparison
- Relay Monitor
- Consequences for misbehavior relays
- SSZ encoding
- MEV-Boost security audit
- ValidatorRegistration and [Data API Privacy](https://collective.flashbots.net/t/privacy-concerns-with-data-api/568/2)
## Updates Since Devcon
- Flashbots continues to maintain MEV-Boost via an ‘open R&D’ process, where releases and updates will be shared openly on the [Flashbots Forum.](https://collective.flashbots.net/c/relays/15)
- We are iterating on inclusion list or partial block auction design decisions which ideally will not require consensus client integration.
- We’ve doubled the boost-relay builder block submission rate limit to 600/5min (2/sec), which is pretty optimal for block builders.
- [Announced mev-boost-relay v0.11.0 - notable feature: block submission cancellations](https://collective.flashbots.net/t/announcing-mev-boost-relay-v0-11-0-notable-feature-block-submission-cancellations/604).
- [We’ve open sourced our sync-proxy](https://collective.flashbots.net/t/open-sourcing-sync-proxy/626), which allows EL clients (i.e. geth, nethermind, etc.) to be driven by multiple beacon nodes for greater redundancy.
## Community Updates
- [Prysm](https://github.com/prysmaticlabs/prysm/pull/11557) (Terence) and [Geth](https://github.com/ethereum/go-ethereum/pull/25998) (Marius) prototyping features to enable the proposer to select between a local block and a builder block with the highest fee.
- New relay and builder entrants: The [@Rook](https://twitter.com/Rook) relay undergoing load testing, [Builder0x69](https://medium.com/@builder0x69/first-10-000-blocks-and-new-features-8b3bb0e5b4a7) considering entering.
- BloXRoute [discussion regarding validator specified censorship](https://collective.flashbots.net/t/discussion-regarding-validator-specified-censorship/615).
- Forum: [A Full-Block-Censoring FlashBots Relay For Censorship-Sensitive Proposers](https://collective.flashbots.net/t/request-a-full-block-censoring-flashbots-relay-for-censorship-sensitive-proposers/593)
## Requested Next Steps
- Continue discussion on [incentivizing relays](https://collective.flashbots.net/t/ideas-for-incentivizing-relays/586) to increase competition.
- Align on the standardization of block scoring and [adding bid proofs](https://github.com/ethereum/builder-specs/pull/51) to the builder bid response [https://collective.flashbots.net/t/block-scoring-for-mev-boost-relays/202/16](https://collective.flashbots.net/t/block-scoring-for-mev-boost-relays/202/16).
- Continue iteration of [inclusion list or partial block auction design decisions](https://hackmd.io/5rrA0KfBTFS7uvIEg41Lag) by answering open questions.
- Contribute toward the [MEV-Boost development philosophy](https://collective.flashbots.net/t/mev-boost-development-philosophy/505).
- Implement the changes required for local and remote block building comparison.
- Review the inclusion list proposal: [How much can we constrain builders without bringing back heavy burdens to proposers?](https://ethresear.ch/t/how-much-can-we-constrain-builders-without-bringing-back-heavy-burdens-to-proposers/13808)
