I would like have a step by step process to get block production started with a parachain on Rococo testnet.

1 Answer 1


First make sure you test locally:

When you're ready for testing on Rococo testnet, you can follow this guide:

Once a Parity team member with sudo has uploaded your wasm and genesis state to the Rococo relay chain via the subport issue you filled out, you will have a temporary slot and can then run your collator and start producing blocks.

  • In docs for Relay Chain Locally, we are having a rococo_local_relay_chain_spec.json, when we are having a parathread upgraded to parachain, what is process of step by step i would like to know eg:- how to start a relay chain for my parachain?(how to configure .json file)

  • The commands are the same as in the tutorial, just make sure you use the Rococo chain spec: github.com/paritytech/polkadot/blob/master/node/service/… and modify your parachain's chain spec for production. You can look at other parachain team's chain spec for examples.
