In this tutorial you are going to build the EVM from scratch.

The EVM is a central part of Ethereum. It is Ethereum’s execution engine, responsible for executing Ethereum programs, also called Smart Contracts.

In this tutorial we are going to build the EVM from scratch. However, this is not a reference implementation. I will omit implementation details if I believe they are not necessary for understanding how the EVM works. This is about learning the core concepts of the EVM from first principles.

That is why I want to call it a mini-EVM. A working but simplified version of the real thing. A virtual machine that takes in an Ethereum program as input and executes that.
