Implementation of a Crust protocol node with substrate.

Join to play

Go to our Crust Node, follow the README.

Building

Build from source

1. Install Rust

If, after installation, running rustc --version in the console fails, refer to it to repair.

curl https://sh.rustup.rs -sSf | sh

2. Initialize your Wasm Build environment

./scripts/init.sh

3. Build Wasm and native code

cargo build --release

Build from docker

Refer this to see how to build and run crust with docker.

Network

1. Connect to maxwell

./target/release/crust --chain=maxwell

Get the bootnodes from Crust Network Team, see more from wiki.

2. Connect to rocky

Archived chain for only internal test now.

./target/release/crust --chain=rocky

Get the bootnodes from Crust Network Team, see more from wiki.

3. Run as dev

Purge any existing developer chain state:

./target/release/crust purge-chain --dev

Start a development chain with:

./target/release/crust --dev

Detailed logs may be shown by running the node with the following environment variables set: RUST_LOG=debug RUST_BACKTRACE=1 cargo run -- --dev.

4. Run as local

If you want to see the multi-node consensus algorithm in action locally, then you can create a local testnet with two validator nodes for Alice and Bob, who are the initial authorities of the genesis chain that have been endowed with testnet units.

You'll need two terminal windows open.

We'll start Alice's substrate node first on default TCP port 30333 with her chain database stored locally at /tmp/alice. The bootnode ID of her node is 12D3KooWEyoppNCUx8Yx66oV9fJnriXwCcXwDDUA2kj6vnc6iDEp, which is generated from the --node-key value that we specify below:

./target/release/crust \
  --base-path /tmp/alice \
  --chain local \
  --alice \
  --node-key 0000000000000000000000000000000000000000000000000000000000000001

In the second terminal, we'll start Bob's substrate node on a different TCP port of 30334, and with his chain database stored locally at /tmp/bob. We'll specify a value for the --bootnodes option that will connect his node to Alice's bootnode ID on TCP port 30333:

./target/release/crust \
  --base-path /tmp/bob \
  --chain local \
  --bob \
  --port 30334 \
  --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/12D3KooWEyoppNCUx8Yx66oV9fJnriXwCcXwDDUA2kj6vnc6iDEp

Additional CLI usage options are available and may be shown by running cargo run -- --help.
