Acurast Substrate is a Cumulus-based parachain. The Cumulus Parachain Template was used as the base for the node and runtime implementation.

cargo build --release

First build the plain chain spec:

./target/release/acurast-node build-spec --disable-default-bootnode > acurast-local-parachain-plain.json

In acurast-local-parachain-plain.json set the parachain id to 2000 by:

• changing the value of para_id at the root level
• changing the value at genesis.runtime.parachainInfo.parachainId

Then create the raw version of the chain spec:

./target/release/acurast-node build-spec --chain acurast-local-parachain-plain.json --raw --disable-default-bootnode > acurast-local-parachain-2000-raw.json

Now run the node with the following command:

RUST_LOG=runtime=trace ./target/release/acurast-node --alice --collator --force-authoring --chain acurast-local-parachain-2000-raw.json --base-path /tmp/parachain/alice --rpc-port 8080 --port 40333 --ws-port 8844 --unsafe-rpc-external --unsafe-ws-external --rpc-cors all -- --execution wasm --chain ../polkadot/acurast-local-raw.json --port 30343 --ws-port 9977

The above command assumes that there is a rococo relay chain with the raw spec at ../polkadot/acurast-local-raw.json.
