"Sadly, there has been very little in the way of a clear definition of MEV in the context of Bitcoin.

And the standard definition of the term is so broad as to be entirely useless in discussions of protocol risk." — Matt Corallo

As Bitcoin's functionality expands, concerns arise about the potential sacrifice of its core value of censorship resistance.

A concept originating from the Ethereum community, Miner Extractable Value (MEV), refers to the profit miners can make by manipulating transaction order or inclusion in a block.

While some argue that MEV is a natural outcome of competitive mining, others believe it threatens the network's decentralization.

To address this issue, some suggest redefining MEV to differentiate between unavoidable forms and the more insidious "MEVil" that endangers decentralization.
