EVM From Scratch

Welcome to EVM From Scratch! It's a 100% practical course that will help you better understand the inner workings of the Ethereum Virtual Machine. During this course, we'll implement EVM in your favorite programming language.

Getting Started

Clone the repo:

git clone https://github.com/w1nt3r-eth/evm-from-scratch

This repository contains evm.json file with test cases. Your goal is to create an implementation in any programming language of your choice that passes all tests.

The test cases are organized by complexity: they start with the simplest opcodes and gradually progress to advanced. Each test case has a name, code and expectation. The code is provided as a human-readable instructions list (asm) and machine-readable bytecode encoded in hex (bin). Your implementation should only look at bin, the asm is provided to make unit tests easier to debug.

The repository contains templates for JavaScript, TypeScript, Python, Go and Rust. However, you don't have to use the existing templates, you can build your own test suite based on evm.json (or evm-pro.json, see below).

Additional tests

To use the paid test suite, place evm-pro.json in the repository root, next to evm.json. The Pro version has more than 200 test cases that gradually walk you through implementing your own EVM.
