It passes all `ethereum/tests` test suites.

Here is a list of guiding principles that Revm follows.

- **EVM compatibility and stability** - this goes without saying but it is nice to put it here. In the blockchain industry, stability is the most desired attribute of any system.
- **Speed** - is one of the most important things and most decisions are made to complement this.
- **Simplicity** - simplification of internals so that it can be easily understood and extended, and interface that can be easily used or integrated into other projects.
- **interfacing** - `[no_std]` so that it can be used as wasm lib and integrate with JavaScript and cpp binding if needed.

Structure:

* revm -> main EVM library.
* revm-primitives -> Primitive data types.
* revm-interpreter -> Execution loop with instructions
* revm-precompile -> EVM precompiles
* bins:
* revme: cli binary, used for running state test jsons

This project tends to use the newest rust version, so if you're encountering a build error try running `rustup update` first.

There were some big efforts on optimization of revm:
* Optimizing interpreter loop: https://github.com/bluealloy/revm/issues/7
* Introducing Bytecode format (and better bytecode analysis): https://github.com/bluealloy/revm/issues/121
* Unification of instruction signatures: https://github.com/bluealloy/revm/pull/283

# Building from source

```shell
git clone https://github.com/bluealloy/revm.git
cd revm
cargo build --release
```

**_Note:_** `clang` is required for building revm as `c-kzg` is used as a dependency. If you don't have it installed, you can install it with `apt install clang`.
