edgeware-node

A Parity Substrate node implementing Edgeware.

Fresh start

If your device is clean (such as a fresh cloud VM) you can use this script, otherwise, proceed with the Initial Setup.

./setup.sh

Then proceed to the Running instructions or follow the instructions below for the manual setup.

Initial Setup

curl https://sh.rustup.rs -sSf | sh
rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly
rustup update stable
cargo install --git https://github.com/alexcrichton/wasm-gc

You will also need to install the following packages:

Linux:

sudo apt install cmake pkg-config libssl-dev git clang libclang-dev

Mac:

brew install cmake pkg-config openssl git llvm

Building

./build.sh
cargo build --release

Running

Ensure you have a fresh start if updating from another version:

./purge-chain.sh

To start up the Edgeware node and connect to the latest testnet, run:

./target/release/edgeware --chain=edgeware --name <INSERT_NAME>

If you use the --key flag, ensure that either it is a 32-byte hex string or prefixed with // like so:

./target/release/edgeware --chain=edgeware --name <INSERT_NAME> --key //testkey

Visualization

To ensure you followed the steps correctly, check https://telemetry.polkadot.io/#/Edgeware%20Testnet%20V0.2.0. If done correctly, you should see your node with the inserted name.

Developing on Edgeware

Running A Local Chain

To run a chain locally for development purposes: ./target/release/edgeware --chain=local --alice --validator

To force your local to create new blocks, even if offline, add the --force-authoring flag.

Adding A Module

1. Add its github repo to:

• Cargo.toml
• node/runtime/Cargo.toml
• node/runtime/wasm/Cargo.toml (be sure to have default-features = false)

2. Changes to the runtime:

• Add it as an extern crate.
• Implement its Trait with production types.
• Add it to the construct_runtime macro with all implemented components.

3. If its storage contains config elements, then you need to modify the chain spec:

• Add it to the edgeware_runtime's list of Config types.
• Add it to the testnet_genesis function, initializing all storage fields set to config().

4. Build and run the chain.
