MEV Army is a collection of shadowy super coders lurking in the Ethereum dark forest, ready to exploit transactions and extract profit. MEV, as initially defined by Phil Daian in Flash Boys 2.0, stands for Miner Extractable Value. MEV is extra value or profit captured by miners who censor and reorder transactions in a block they produce. Each Miner in MEV Army is composed of the original transaction ordering code from go-ethereum.
