    • MEV
      • Maximal (formerly “miner”) Extractable Value refers to the maximum value that can be extracted from block production in excess of the standard block reward and gas fees by including, excluding, and changing the order of transactions in a block
        • In the context of PoW, miners control transaction inclusion, exclusion, and ordering
        • Independent network participants called “searchers” who run complex algorithms on blockchain data to detect profitable MEV opportunities and have bots to automatically submit those profitable transactions to the netowkr
