Differences Between Ethereum and mev-commit Chain

Introduction

Mev-commit chain is an Ethereum-compatible blockchain designed to provide faster transaction processing and lower fees. It aims to optimize the extraction of Maximal Extractable Value (mev) by utilizing a specialized architecture. This document highlights the key differences between Ethereum and mev-commit chain.

Overview

The following table provides an overview of the key features and differences between Ethereum and mev-commit chain:

Feature	Ethereum	Mev-Commit Chain
Mempool	Larger mempool size	Smaller mempool size, transactions may be encrypted, limited chain mempool visibility due to fewer chain node operators
Validators	Decentralized proof of stake system with a large number of validators	Centralized setup with only two validator nodes creating blocks in a round-robin fashion, allowing for faster consensus and block production
Opcodes	Supports Ethereum opcodes	Supports all Ethereum opcodes, ensuring compatibility with existing Ethereum smart contracts and tools
Consensus	Uses proof of stake consensus, prioritizing decentralization	Uses clique proof of authority consensus, where authorized validators take turns creating blocks, prioritizing performance and fast block times
Block time	12 seconds	200 milliseconds
Transaction Fees	Supports both legacy and EIP-1559 transactions, with base fee being burned and priority fee going to the proposer/signer	Supports both legacy and EIP-1559 transactions, with base fee directed to the protocol treasury and priority fee going to the proposer/signer

Transaction Fees

Like Ethereum, mev-commit chain supports both legacy and EIP-1559 transactions, with a preference for EIP-1559.

The allocation of fees differs:

• The base fee is directed to the protocol treasury, instead of being burned.
• The priority fee goes to the proposer/signer, as in Ethereum.

Mempool

Mev-commit chain’s mempool is smaller compared to Ethereum’s. While the mempool is public, transactions may be encrypted, and chain mempool visibility is limited due to the presence of only a few chain node operators. This reduces the potential for front-running and other mev-related activities.

Number of Validators

Mev-commit chain currently operates with only two validator nodes that create blocks in a round-robin fashion. This centralized setup allows for faster consensus and block production. However, it also introduces a higher level of trust in the validators compared to Ethereum’s decentralized proof of stake system.

Opcodes

Mev-commit chain supports all Ethereum opcodes, as it consists of Ethereum nodes. Opcodes are low-level instructions that define the operations a blockchain can perform. By supporting all Ethereum opcodes, mev-commit chain ensures compatibility with existing Ethereum smart contracts and tools.

Consensus

Mainnet Ethereum uses proof of stake, while mev-commit chain currently uses clique proof of authority consensus. In clique proof of authority, a set of authorized validators take turns creating blocks. This consensus mechanism prioritizes performance and fast block times over decentralization.

Conclusion

Mev-commit chain offers a specialized blockchain environment optimized for mev extraction. With faster block times, a different fee structure, and a centralized validator setup, mev-commit chain provides an alternative to Ethereum for use cases that prioritize speed and mev optimization.
