Ethereum Virtual Machine written in rust that is fast and simple to use

revm

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:

• Optimizing interpreter loop: bluealloy#7
• Introducing Bytecode format (and better bytecode analysis): bluealloy#121
• Unification of instruction signatures: bluealloy#283

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
