Felidae Network Node

This repo contains the code for the felidae network blockchain.

Node Setup

This node has been tested for Ubuntu version 20.04.

Install dependencies

Use a terminal shell to execute the following commands:

sudo apt update
# May prompt for location information
sudo apt install -y cmake pkg-config libssl-dev git build-essential clang libclang-dev curl

Rust Developer Environment

This project uses rustup to help manage the Rust toolchain. First install and configure rustup:

# Install
curl https://sh.rustup.rs -sSf | sh
# Configure
source ~/.cargo/env

Finally, configure the Rust toolchain:

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

Run

Use Rust's native cargo command to build and launch the template node:

cargo run --release -- --dev --tmp

Build

The cargo run command will perform an initial build. Use the following command to build the node without launching it:

cargo build --release

Embedded Docs

Once the project has been built, the following command can be used to explore all parameters and subcommands:

./target/release/felidae-node -h

Run

The provided cargo run command will launch a temporary node and its state will be discarded after you terminate the process. After the project has been built, there are other ways to launch the node.

Single-Node Development Chain

This command will start the single-node development chain with persistent state:

./target/release/felidae-node --dev

Purge the development chain's state:

./target/release/felidae-node purge-chain --dev

Start the development chain with detailed logging:

RUST_LOG=debug RUST_BACKTRACE=1 ./target/release/felidae-node -lruntime=debug --dev

Node

A blockchain node is an application that allows users to participate in a blockchain network.

After the node has been built, refer to the embedded documentation to learn more about the capabilities and configuration parameters that it exposes:

./target/release/felidae --help

Multi-Node Testnet

Generate node key

Generate pubic key from a secret phrase. This secret phrase is dedicated to development and should not be used in any other places.

./target/release/felidae-node key inspect --scheme ed25519 "spirit scan alone brave volume gallery put order index before eager update"

Secret phrase:       spirit scan alone brave volume gallery put order index before eager update
  Network ID:        substrate
  Secret seed:       0xcad0be1eb91ac5000b0f2b163430cdcc601bcfa65be61703b2376381a3387eda

  SS58 Address:      5DoNnbvKvthQZ2YNzjtkU1rbQmMvo8zQAW4wK2FPR4U6H5ZK

Save this public key 0x4cc79714885dced625d7fbf8341008ae4a1fb714452a62c50456597f29ecc270

Config validators' session keys

Config validators secret phrase in testnet.sh.

# Copy paste your mnemonic here.
SECRET="universe toast because trouble bulb inmate cruel shock erode border hour entry"

This command will generate 4 validator session keys.

./scripts/testnet.sh 4

Replace the session keys from vec![...] in node/cli/src/chain_spec.rs with above generated keys.

fn staging_testnet_config_genesis() -> GenesisConfig {
    let initial_authorities: Vec<(AccountId, AccountId, GrandpaId, BabeId, ImOnlineId, AuthorityDiscoveryId)> = vec![...];
    #--snip--
}

Recompile

cargo build --release

Remove prefix 0x of public key, replace the root key in node/cli/src/chain_spec.rs

let root_key: AccountId = array_bytes::hex_n_into_unchecked(
