'What is the Difference Between Miner Extractable Value vs Maximal Extractable Value' blockchain tatum_io
In a proof-of-work consensus blockchain, the use of miners to approve transactions and add new blocks to the blockchain for an immutable record is an integral part of the decentralized blockchain protocol.
In a proof of work consensus blockchain, due to the small number of transactions per second allowed by PoW consensus blockchain, transactions are not immediately added to the block but need to be confirmed before adding to a new block hash; hence, the transaction will remain in the waiting area, also known as txpool.
MEV gives miners and searchers the ability to use complex algorithm bots to manipulate the ordering of their transactions to include or exclude within a block by changing the transaction fee they pay to block producers.Miners are the group of peer-2-peer node operators that confirm transactions on a proof-of-work consensus blockchain by solving complex computational mathematics for a block reward.
This occurs because miners possess the ability to reorganize, include and exclude transactions at their own will, using their position of privileged information to execute a trade first by taking advantage of the trading opportunities the user’s transactions signal. The establishment of miner extractable value has provided dualistic effect and utility to proof-of-work blockchains in both good and bad ways.
Decentralized exchange arbitrage is the simplest and most well-known miner extractable value opportunity. As a result, it is also the most competitive. It works like this: if two DEXes are offering a token at two different prices, someone can buy the token on the lower-priced decentralized exchange and sell it on the higher-priced decentralized exchange in a single, atomic transaction. Thanks to the mechanics of the blockchain, this is true, riskless arbitrage.
Some forms of miner extractable value, like sandwich trading, results in an unequivocally worse experience for users. Users who are sandwiched face increased slippage and worse execution on their trades.Generalized frontrunners, back running, and the gas-price auctions they often engage in result in network congestion and high gas prices for everyone else trying to run regular transactions.
