This guide uses https://rustup.rs installer and the rustup tool to manage the Rust toolchain. First install and configure rustup:

# Install
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
# Configure
source ~/.cargo/env

Configure the Rust toolchain to default to the latest stable version, add nightly and the nightly wasm target:

rustup default nightly
rustup update
rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly

Great! Now your Rust environment is ready! 🚀🚀

Clone the submodules:

# clone the repo
git clone [email protected]:webb-tools/protocol-substrate.git

# Fetch submodules
git submodule update --init

Build the node in release mode:

cargo build --release

Install Homebrew if you have not already. You can check if you have it installed with the following command:

brew help

If you do not have it installed open the Terminal application and execute the following commands:

# Install Homebrew if necessary https://brew.sh/
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

# Make sure Homebrew is up-to-date, install openssl
brew update
brew install openssl

❗ Note: Native ARM Homebrew installations are only going to be supported at /opt/homebrew. After Homebrew installs, make sure to add /opt/homebrew/bin to your PATH.

echo 'export PATH=/opt/homebrew/bin:$PATH' >> ~/.bash_profile

In order to build protocol-substrate in --release mode using aarch64-apple-darwin Rust toolchain you need to set the following environment variables:

echo 'export CC="/opt/homebrew/opt/llvm/bin/clang"' >> ~/.bash_profile
echo 'export AR="/opt/homebrew/opt/llvm/bin/llvm-ar"' >> ~/.bash_profile

In order to run the standalone development network, you will need to prepare 2 terminal windows. Once the below commands are executed it will set up a development network using the BABE consensus mechanism for a 2 node network.

Terminal 1:

./target/release/webb-standalone-node --dev --alice --node-key 0000000000000000000000000000000000000000000000000000000000000001

Terminal 2:

./target/release/webb-standalone-node --dev --bob --port 33334 --tmp   --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/12D3KooWEyoppNCUx8Yx66oV9fJnriXwCcXwDDUA2kj6vnc6iDEp

You now have successfully set up a standalone local testnet! 🎉

To build the standalone docker image specified in docker/ :

docker build -f ./docker/Standalone.Dockerfile -t protocol-substrate/standalone .

To run docker image:

docker run protocol-substrate/standalone

The following instructions outlines how to run the protocol-substrate base test suite and integration test suite.

cargo test --release --workspace --exclude webb-client

1. Run cd scripts
2. Run sh run-integrations.sh

You need to have docker installed to generate code coverage.

Build docker image:

docker build -t cov -f docker/Coverage.Dockerfile .

Run docker image and generate code coverage reports:

docker run --security-opt seccomp=unconfined cov
