SputnikVM: Rust Ethereum Virtual Machine Implementation

Build Status License

NameDescriptionCrates.ioDocumentation
evmCore library for the Ethereum Virtual Machinecrates.ioDocumentation
evm-statefulMerkle Trie stateful wrapper for SputnikVMcrates.ioDocumentation

Features

  • Standalone - can be launched as an independent process or integrated into other apps
  • Universal - supports different Ethereum chains, such as ETC, ETH or private ones
  • Stateless - only an execution environment connected to independent State storage
  • Fast - main focus is on performance
  • IoT compatible - designed to support hardware used in embedded devices
  • written in Rust, can be used as a binary, cargo crate or shared library

Precompiled Contracts

The core library has the initial four precompiled contracts embedded. To use the bn128 and modexp precompiled contracts introduced by the Byzantium hard fork, pull the following crates.

NameDescriptionCrates.ioDocumentation
evm-precompiled-bn128bn128 precompiled contractscrates.ioDocumentation
evm-precompiled-modexpmodexp precompiled contractscrates.ioDocumentation
  • ethereum-rs - common traits and structs for Ethereum.
  • etclient - bare-minimal Ethereum client written in Rust.
  • SputnikVM FFI - SputnikVM C and Go FFI bindings
  • SputnikVM Dev - SputnikVM instance for Smart Contract development, provides testing environment and mock for JSON RPC API
  • SputnikVM in Browser - experimental version of SputnikVM compiled into WebAssembly, therefore can be launched in a browser on Node.js
  • SputnikVM for embedded devices - experimental project to run on full functional EVM on embedded devices

Dependencies

Ensure you have at least rustc 1.33.0 (2aa4c46cf 2019-02-28). Rust 1.32.0 and before is not supported.

Documentation

Build from sources

SputnikVM is written Rust. If you are not familiar with Rust please see the getting started guide.

Build

To start working with SputnikVM you'll need to install rustup, then you can do:

$ git clone git@github.com:ethereumproject/evm-rs.git
$ cd evm-rs
$ cargo build --release --all

Testing

We currently use two ways to test SputnikVM and ensure its execution aligns with other Ethereum Virtual Machine implementations:

  • jsontests: This uses part of the Ethereum tests. Those tests currently do not have good coverage for system operation opcodes. Besides, some tests are incorrect so they are disabled.
  • regtests: A complete regression tests is done on the Ethereum Classic mainnet from genesis block to block 4 million. Some of the previously failed tests are also integrated into Rust's test system.To run all tests, execute the following command in the cloned repository:
    $ cargo test --all
