I wanted to try out starting multple parachain node and not only one node-collator like in this documentation.

How can I remove the force-authoring successfully and have multiple nodes that uses the AURA consensus. Lets imagine there would be only one collator and 3-4 parachain nodes.

I suppose the collator would still look like:

./target/release/parachain-collator \
--alice \
--collator \
--force-authoring \
--chain rococo-local-parachain-2000-raw.json \
--base-path /tmp/parachain/alice \
--port 40333 \
--ws-port 8844 \
-- \
--execution wasm \
--chain <relay chain raw chain spec> \
--port 30343 \
--ws-port 9977

But what about the other nodes ? How would the setup look like ?

Note: I was thinking of using substrate-validator-set to add aura authorities one by one. But I don't get the "startup command" to work.

Force authoring is only required if you are setting up a single node, what you could do is set up multiple ones and point them to each other using

  1. Adding bootnodes in the spec, see how it's done for statemine here
  2. the --bootnode flag, see docs and an example

Personally I think you are best setting the bootnodes in the spec that is generated as this seems to be the best practice among most running chains including the relay (rococo/westend/kusama/dot)
