Acurast Substrate is a Cumulus-based parachain. The Cumulus Parachain Template was used as the base for the node and runtime implementation.
To learn more about Acurast please visit the website and documentation.

make startFirst 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_idat 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.
