Flashbots is a research and development organization focused on addressing the challenges posed by Maximal Extractable Value (MEV) in stateful blockchains, starting with Ethereum. MEV refers to the profit that can be extracted by reordering, including, or excluding transactions within a block. Flashbots aims to create a permissionless, transparent, and sustainable ecosystem for MEV by developing solutions that mitigate its negative externalities.

Flashbots operates in the blockchain and cryptocurrency market, primarily serving blockchain developers, validators, and miners. The organization’s business model revolves around providing tools and infrastructure that enable validators to maximize their staking rewards by selling blockspace to an open market of builders. This is achieved through their implementation of proposer-builder separation (PBS) in Ethereum's proof-of-stake mechanism.

Flashbots makes money by facilitating transactions and interactions within the blockchain ecosystem, ensuring that validators and block builders can operate efficiently and profitably. Their solutions help prevent the concentration of mining power and promote a fairer distribution of rewards among participants.
