# 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.
