MEV-Week Paris: From Zero Sum To Positive Sum

A journey through MEV discourse.

2020, MEV Roast introduced research dialogue that lit up our journey through the dark forest, open and available to all.

2021, MEV.wtf explored the protocol and application level responses to the problem of MEV in a research unconference curated by 17 researchers, in collab with ETHGlobal.

2022, MEV.day embraced the light-mode and dark-mode of MEV on a dual-stage conference curated by 22 researchers, in collab with the Ethereum Foundation, CowSwap and Shutter Network.

2023 MEV-Week

PBS.day (Jul 22)- Keeping Crypto Decentralized

Note: PBS.day is the Day 2 Main Stage program @Modular Summit

PBS redefined the decade old paradigm of block production from the Bitcoin mining days. - Zaki Manian, 2021 - Catskills, NY

Proposer-builder separation (PBS) is a protocol design philosophy emphasizing the relationship between protocol and non-protocol actors for the maintenance and operation of a blockchain. It was first put forth in Vitalik’s 2021 ethResearch post as a market structure design that leverages the power of specialization to mitigate the centralizing pressure on the validator set from MEV by enabling the block construction process to be outsourced to highly specialized non-protocol actors known as block builders.

The introduction of the MEV-Boost protocol post Merge was an important early step for PBS. Despite its flaws, it has stood as a solid interim out-of-protocol solution as we continue to navigate through the PBS design space: from the elegant PEPC proposal to the latest version of the enshrined PBS (ePBS) design PTC.

  • What is PBS and where are we today? What are the hardest consensus and market design challenges on the Ethereum L1 PBS R&D Roadmap?
  • How does PBS apply to the modular stack? What does PBS on L2s and shared sequencers look like? How applicable is PBS beyond the Ethereum ecosystem?
  • What cool innovations in block building e.g. advanced forms of aggregation can make a difference in augmenting the technical capabilities and improving user experience in the Ethereum ecosystem?

MEV.Salon (Jul 16-22)

MEV hackerhouse meets Parisian Salon. Every day of the week has a different salon for a focused deep dive, curated with your preferences and insights.

Flashbots is plural. Whether you are a builder, re[searcher] or low-carb-crusader, bring your thoughts, hard questions and good memes. Together we can turn zero-sum games into positive-sum games.

Blockspace is scarce and so are salon seats, we’ll build the most profitable block with the most thoughtful content. For a potential seat at the discussions:
:zap: Vote now for the salons that you are interested in attending to help us load balance.
:memo: Reply in the thread below with research questions and insights.
:white_check_mark: Fill in the lu.ma invitations linked with each of the salons.

sauve.salon – I can’t wait to hear some updates on suave from Bert and team! Most interested in learning more about suave smart contracts!

pbs.salon – nothing more important than this this week. PBS is still so important to decentralizing and keeping decentralized public blockchains. Not gonna be one to miss!

I’m also curious about how people feel about redistribution, decentralized orderflow, and how we inspire a new generation of searchers!

interested in the pbs, orderflow, censorship and suave saloons

how should coinbase integrate suave across its products and services?
when will PBS be enshrined into Ethereum? possible this actually happens sooner with rollups?
how do we combat the rise of exclusive order flow?
how will intents change (or not change) the plan for suave?
what are he unintended externalities of intents that we need to be thinking about?

One of the many reasons why I love flashbots is they always collect all the slides in a single post :slight_smile:
