rustup target add wasm32-unknown-unknown --toolchain nightly-2022-01-01

# compile
cargo build --release

Run

Single Node Development Chain

Purge any existing dev chain state:

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

Start a dev chain:

./target/release/deeper-chain --dev

Or, start a dev chain with detailed logging:

RUST_LOG=debug RUST_BACKTRACE=1 ./target/release/deeper-chain -lruntime=debug --dev
