What is Miner Extractable Value?
Miner Extractable Value is the amount of value that can be extracted from a transaction by a miner on top of a blockchain network. This includes both the gas fees paid by users and any additional fees or charges that are levied by the smart contract being used.
To put it simply, when a user sends cryptocurrency to another address, the network uses gas to process that transaction. The more complex the transaction, the more gas is required to process it. This gas fee is paid by the user and goes directly to the miner who processes the transaction.
In addition to the gas fee, smart contracts can also include additional fees or charges that are levied by the contract itself. These fees can be used to incentivize users to interact with the contract in a certain way or to fund the development and maintenance of the contract.
Why is MEV important for crypto developers?
MEV is an important concept for crypto developers because it allows them to create more efficient and cost-effective smart contracts. By including fees or charges within a smart contract, developers can incentivize users to interact with the contract in certain ways, without having to rely solely on gas fees paid by users.
For example, let’s say a developer wants to create a decentralized exchange (DEX) that allows users to trade cryptocurrency. Instead of relying solely on gas fees paid by users, the DEX could also include a small transaction fee as part of the contract. This would incentivize users to use the DEX more frequently and help to offset the costs associated with running the network.
In addition to incentivizing user behavior, MEV can also help to fund the development and maintenance of smart contracts. By including additional fees or charges within a contract, developers can generate revenue from the contract itself, which can be used to fund ongoing development and maintenance efforts.
Case Studies in MEV
There are several case studies that demonstrate the importance of MEV for crypto developers. One such example is the DeFi ecosystem. DeFi refers to decentralized finance applications that allow users to interact with cryptocurrency on a peer-to-peer network, rather than relying on traditional financial institutions.
One of the key components of the DeFi ecosystem is smart contracts. These contracts are self-executing and can be used to automate a wide range of financial transactions, such as lending, borrowing, and trading. By including fees or charges within these contracts, developers can incentivize users to interact with the contract in certain ways, without having to rely solely on gas fees paid by users.
Another example is the Ethereum Name Service (ENS). ENS allows users to create human-readable names for their cryptocurrency wallet addresses, making it easier to share and manage their cryptocurrency holdings. By including a small transaction fee as part of the contract, developers can generate revenue from the use of the ENS service, which can be used to fund ongoing development efforts.
