Flashbots, for its part, has grown in prominence since Ethereum switched to proof-of-stake in September. Today, 94% of the blocks (bundles of transactions) written to the Ethereum ledger come from MEV-Boost, a piece of Flashbots middleware that delivers pre-made, maximum extractable value-optimized blocks to the validators that add them to the blockchain. Flashbots also made waves two months ago with the announcement that it was building SUAVE – a new blockchain that will run in parallel with other networks to provide a kind of decentralized MEV market.
