Crust · Build Status Substrate version GitHub license

Funded by web3 foundation     

Implementation of a Crust Protocol node with substrate.

🎮 Join to Play

Please go to crust wiki, refer the node overview.


⌨️ Build from source

1. Install rust

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

curl -sSf | sh

2. Initialize your wasm build environment


3. Build wasm and native code

cargo build --release

*4. Troubleshooting

Depending on different building environments, if you cannot build the source code, please check the detail error message and try to run the corresponding commands to fix it

  • Debian/Ubuntu/Raspbian
sudo apt install gcc-multilib

chmod +x ./
sudo ./ 10
sudo ln -s /usr/lib/llvm-10/bin/llvm-config /user/bin/llvm-config

sudo apt install gcc
sudo apt install clang
  • Fedora/RedHat/CentOS
sudo yum -y install gcc
sudo yum -y install clang

Also, you can join discord to get help

🐳 Dockerize

Please refer this to see how to build and run crust with docker.

⛰ Live Network

1. Connect to mainnet

The default branch mainnet can be build and connect to mainnet.

./target/release/crust --chain mainnet

To speed up the synchronization process, please add the following parameters.

--execution=wasm --wasm-execution=compiled

2. Connect to maxwell

Please checkout the branch release/0.11.1, then build and connect to maxwell

./target/release/crust --chain maxwell

Get the bootnodes from here.

🍕 Dev Network

1. Connect to rocky

Rocky has the same function and parameters with Mainnet, developers can deploy applications on this free test network. Read more about rocky.

./target/release/crust --chain rocky

2. 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.

3. 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/

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