Rust Ethereum Virtual Machine

Revm is an EVM written in Rust that is focused on speed and simplicity. It has a fast and flexible implementation with a simple interface and embedded Host. 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.

Project

Structure:

  • crates
    • 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:

Building from source

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

Note: clang is required for building revm with c-kzg or secp256k1 feature flags as they depend on C libraries. If you don't have it installed, you can install it with apt install clang.

Running eth tests

go to cd bins/revme/

Download eth tests from (this will take some time): git clone https://github.com/ethereum/tests

run tests with command: cargo run --release -- statetest tests/GeneralStateTests/ tests/LegacyTests/Constantinople/GeneralStateTests

GeneralStateTests contains all tests related to EVM.

Running benchmarks

TODO needs to be updated. Benches can now be found inside crates/revm/benches

cargo run --package revm-test --release --bin snailtracer
cargo flamegraph --root --freq 4000 --min-width 0.001 --package revm-test --bin snailtracer

Running example

cargo run -p revm --features ethersdb --example fork_ref_transact
