Single Node Development Chain

Purge any existing dev chain state:

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

Start a dev chain:

./target/release/trackback-node --dev

Or, start a dev chain with detailed logging:

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

Multi-Node Local Testnet

If you want to see the multi-node consensus algorithm in action, refer to our Start a Private Network tutorial.
