PEVM

This project implements an Ethereum Virtual Machine (EVM) command executor, leveraging Rust's powerful concurrency features. The executor processes blocks from a blockchain, performing transactions in parallel using multiple threads to maximize efficiency.

Features

• Executes EVM commands over a specified range of blocks.
• Utilizes a multi-threaded approach to improve execution speed.
• Supports dynamic task allocation and load balancing across threads.
• Provides real-time execution progress monitoring.

Dependencies

The project relies on several external crates:

• clap for command-line argument parsing.
• eyre for error handling.
• tracing for logging.
• reth_* crates for blockchain-related functionalities.
• num_cpus to determine the number of CPU cores.

Installation

1. Ensure you have Rust installed. If not, install it from rustup.rs.
2. Clone the repository:

   git clone <repository-url>
   cd <repository-directory>

3. Build the project:

   cargo build --release

Usage

The main functionality is provided by the EvmCommand struct, which is configured and executed through the command line.

Command Line Arguments

• --begin or -b: Begin block number (required).
• --end or -e: End block number (required).
• --step or -s: Step size for loop, default is 100.

Example

To execute the EVM command for blocks from 1000 to 2000 with a step size of 50, run:

cargo run --release -- -b 1000 -e 2000 -s 50

Code Overview

The core functionality is implemented in the EvmCommand struct. The execute method performs the following steps:

• Initializes the environment and consensus.
• Configures the blockchain tree and provider.
• Validates the block range.
• Creates a task queue and divides the block range into tasks.
• Spawns multiple threads to process the tasks concurrently.
• Monitors and logs the execution progress in real-time.
• Joins the threads and handles any errors that occur during execution.

Task Execution

Each thread fetches tasks from a shared task queue, processes blocks within the specified range, and updates shared counters for gas usage, block count, and transaction count. The execution results are logged for monitoring.

Real-Time Monitoring

A separate thread periodically logs the current progress, including the number of processed blocks, transactions, and gas throughput.
