# Introduction

MEV, short for Maximal Extractable Value, refers to the additional value that miners or validators can extract from a block beyond the standard transaction fees. By having the power to choose which transactions go into a block and their order, validators/miners can potentially take advantage by including their own transactions and prioritizing them over others in the mempool.
