 ## Background:
 
-Nearly half a decade ago, Flashboys 2.0 2 was published highlighting how arbitrage bots were challenging the promise of blockchains. On the back of this, some of the authors and community members started a research collective to provide solutions to tackle these challenges. In the end, these efforts created a product more broadly known as MEV-boost.

 MEV-boost is a middleware that allows the proposer to make a wholesale commitment that outsources block building to a sophisticated actor called a block builder. In return, these block builders pack a block to earn the highest fee for the proposer. Today, over 90% of blocks are built with proposer commitments.
