miner extractable value

Miner Extractable Value (MEV) is a way for miners to earn extra money for their work in verifying a transaction on the blockchain - the digital ledger that keeps track of all cryptocurrency transactions. When a miner solves a block (group of transactions), they get a reward in the form of newly created cryptocurrency coins. MEV allows miners to make more money by taking a small fee when they verify a transaction. This fee is split between the miner and the cryptocurrency network where the transaction took place. So miners make some extra money, and the network makes sure that its transactions are secure.
