Flashbots

Flashbots is a research and development organization working on mitigating the negative externalities of Maximal Extractable Value (MEV) and avoiding the existential risks MEV could cause to stateful blockchains like Ethereum. Our primary focus is to enable a permissionless, transparent, and sustainable ecosystem for MEV, via a three-pronged approach:

  • Illuminate: bringing transparency to MEV activity, quantifying its impact, and reducing information asymmetry between participants.
  • Democratize: democratizing access to MEV via open platforms that maximize competition and are freely available to all.
  • Distribute: enabling sustainable distribution of any remaining MEV.

Our efforts are separated into three sub-organizations:

  • Product: builds core infrastructure and ecosystem tooling that redefines the block production supply chain. This includes MEV-Boost, BuilderNet, Rollup-Boost, Protect RPC, and SUAVE.
  • Research: an open, transparent, and collaborative research effort that explores MEV market dynamics and blockchain design challenges at the intersection of economics, security, and cryptography. To fuel the collaborative nature of our research, anybody can submit a Flashbots Research Proposal (FRPs) and might become eligible for a grant.
  • Coordination: an organizational effort to streamline operational processes, interface with external teams in the ecosystem and scale ourselves to maximize our impact.

Flashbots Research and Product are tightly-coupled dual engines that propel our organization forward in a phased approach:

  • Long-term oriented research efforts spec out and update our roadmap, define our organization’s phases and identify key milestones.
  • Milestone-oriented engineering efforts ship core infrastructure and ecosystem tools while collecting data and other artifacts that feed back into research.

Our work is open source and you can follow our progress in each respective repository of the Flashbots organization. Anyone is welcome to comment on an issue or pick it up entirely.

Community

The best way to interact with the Flashbots community is through our forum, which is our central communication platform for conversations, announcements and information sharing. We also publish weekly MEV Letters that aggregate information and provide summaries on everything Flashbots and MEV.

Join us!

We are not your typical project, we are fully remote and our principles are based on that of a pirate hacker collective. If you are a self-directed individual who puts collective success above your own and is motivated by solving challenging problems with asymmetric impact, you will fit right in.
