In proof-of-work systems, 'Miner Extractable Value' (MEV) is a term that describes the profits miners can earn by manipulating how transactions are prioritized, excluded, rearranged, or altered in the blocks they mine. However, since Ethereum's upgrade to Ethereum 2.0, which moved the network to proof-of-stake, the concept of MEV has taken on a new name and is now referred to as 'Maximal Extractable Value' in proof-of-stake systems.
Inside a block, transactions are typically ordered with the highest fees at the top, but every now and again opportunities open up that would allow miners to take an additional profit by strategically changing the order of transactions for their own benefit.
