mev-(miner-extractable-value)
MEV, 즉 Miner Extractable Value는 채굴자가 블록 내에서 트랜잭션 순서를 조작하여 얻을 수 있는 이익을 나타냅니다.
MEV는 채굴자(또는 Proof-of-Stake 시스템의 검증자)가 블록 내에서 트랜잭션을 재정렬, 삽입 또는 검열할 수 있는 능력에서 발생합니다. 이를 통해 차익 거래, 프론트 러닝 및 샌드위치 공격과 같은 기회로부터 가치를 추출할 수 있습니다. 추출된 가치는 채굴자가 자산을 구매하는 가격과 판매하는 가격의 차이, 또는 정보 비대칭성을 이용하여 얻는 이익입니다. MEV는 블록체인 공간에서 중요한 문제이며, 네트워크 혼잡, 거래 수수료 증가, 그리고 이를 악용할 자원이 있는 사람들에게 불공정한 이점을 초래할 수 있습니다.

[MEV](/ko/terms/mev) for miners was like a cashier who could decide the order of customers checking out, letting themselves go first if they saw someone about to pay with a rare collectible.
🤓 Expert Deep Dive
The concept of Miner Extractable Value emerged prominently with the growth of decentralized finance (DeFi) on platforms like Ethereum, where on-chain activities created significant economic opportunities exploitable through [transaction ordering](/ko/terms/transaction-ordering). Miners, by controlling block composition, could capture value from arbitrage, liquidations, and other DeFi-native strategies. This power was often exercised through private channels or by observing the public mempool. The 'selfish mining' strategy is related, aiming to maximize block rewards by withholding discovered blocks, but MEV focuses on extracting value within a block. The transition to Proof-of-Stake (PoS) has shifted this power from miners to validators and block builders, leading to the broader term Maximal Extractable Value (MEV), but the fundamental principle of extracting value via block production control remains.
