Build

Install Rust:

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

Install required tools:

./scripts/init.sh

Build Wasm and native code:

cargo build

Run

Single node development chain

You can start a development chain with:

cargo run -- --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.

Multi-node local testnet

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.

Optionally, give each node a name and expose them so they are listed on the Polkadot telemetry site.

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 QmRpheLN4JWdAnY7HGJfWFNbfkQCb6tFf4vvA6hgjMZKrR, which is generated from the --node-key value that we specify below:

cargo run -- \
  --base-path /tmp/alice \
  --chain=local \
  --alice \
  --node-key 0000000000000000000000000000000000000000000000000000000000000001 \
  --telemetry-url ws://telemetry.polkadot.io:1024 \
  --validator

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:

cargo run -- \
  --base-path /tmp/bob \
  --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/QmRpheLN4JWdAnY7HGJfWFNbfkQCb6tFf4vvA6hgjMZKrR \
  --chain=local \
  --bob \
  --port 30334 \
  --telemetry-url ws://telemetry.polkadot.io:1024 \
  --validator

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

2.castor-events-listener

• Store castor network events to MongoDB.

Setup

1. yarn install

Run

1. start mongodb daemon
2. run substrate castor
3. yarn start

.env Configuration

# MongoDB config
MONGO_HOST=127.0.0.1
MONGO_PORT=27017
MONGO_DB=castor_events
MONGO_COLLECTION=event_data

# Substrate Node Config
SUBSTRATE_HOST=localhost
SUBSTRATE_PORT=9944
SUBSTRATE_EVENT_SECTIONS=all
# SUBSTRATE_EVENT_SECTIONS=balances,assets,token,kitties

mongdo - view all events

mongo
use castor_events
db.event_data.find()

TODO

• Maintain block height, deal with sync issues.
• Integer might overflow in mongodb.
• check if challenging multiple times might cause bug

Notes

• uses string for integers that do not need to be compared

---

3.castor-server

• Restful api for castor.network
• relies on castor-event-listener

Setup

yarn install

Run

1. Start MongoDB
2. Run Castor Event Listener
3. Run substrate castor
4. yarn start (default port: 7000)
