What is Backrunning? — MEV Attacks Explained
Backrunning is a specific type of MEV that causes traders to miss out on potential profit opportunities from their trades. It involves strategically executing a transaction immediately after a high-value transaction to capitalize on arbitrage opportunities left over. While backrunning is considered the least harmful type of MEV, it can be combined with other attacks to create the worst kind of MEV, such as sandwich attacks. CoW Swap eliminates backrunning opportunities through its delegated trading mechanism, and MEV Blocker offers rebates for any backrunning opportunities created when trading on Ethereum.

CoW DAO Marks Four Years of MEV Protection with 73M Transactions and $365B Secured
CoW DAO celebrates its fourth anniversary this week, marking significant milestones in protecting DeFi users from MEV (Maximal Extractable Value). **Key Achievements:** - 73.3 million transactions processed - 4.6 million users protected - $365 billion in total value secured The DAO was founded on the principle that users deserve protection while trading. CoW Protocol has demonstrated that MEV protection and smooth user experience can coexist, challenging the notion that security requires sacrificing usability. Recently, CoW DAO transferred its MEV Blocker RPC to Consensys' Special Mechanisms Group, which had protected 4.5M+ users and returned 6,177 ETH in rebates. The DAO continues its MEV protection work through CoW Swap and CoW Protocol.
