What Is Maximal Extractable Value (MEV) and How Is It Related to Front-Running?
MEV is the maximum value that can be extracted from block production by including, excluding, or reordering transactions within a block. Front-running is a specific MEV strategy where an actor sees a pending transaction and inserts their own transaction immediately before it to profit from the anticipated price movement.
Thus, front-running is a subset of the broader MEV concept.
