Substrate Shasper

Note: This is an experimental project. Everything will break, and it may disappear without any notice!

This is an implementation of Shasper beacon chain using the Substrate framework.

Status

Currently we have an implementation of Shasper state transition validation algorithms. This is then combined with LMD-GHOST consensus engine to provide a simple Substrate node implementation with block authoring.

Get Started

To build the project, first install rustup, wasm-gc:

rustup update stable
rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly
cargo +nightly install --git https://github.com/alexcrichton/wasm-gc

Additionally, install clang and llvm, e.g. via the package manager for your distribution.

After that, clone the repo and compile the WebAssembly runtime:

git clone https://github.com/paritytech/shasper.git
cd shasper && ./build.sh

You can then execute the client:

cargo run -- --dev

The client will run and then start proposing and importing blocks.
