SputnikVM: Rust Ethereum Virtual Machine Implementation

Name	Description	Crates.io	Documentation
sputnikvm	Core library for the Ethereum Virtual Machine
sputnikvm-stateful	Merkle Trie stateful wrapper for SputnikVM

Features

• Partially verified (WIP) - use various verification techniques to partially verify the correctness of functions.
• Nightly - take advantage of Rust nightly features, such as compiler plugins
• 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

Supported Networks

• Foundation (evm-network-foundation)
• Classic (evm-network-classic)
• Ellaism (evm-network-ellaism)
• Expanse (evm-network-expanse)
• Musicoin (evm-network-musicoin)
• Ubiq (evm-network-ubiq)

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.

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:etclabscore/sputnikvm.git
$ cd sputnikvm
$ 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 does 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. See wiki for how to reproduce the regression tests.
