Stellar validator node

Question

My question is about running a stellar validator node. Why Starting stellar-core in FORCE_SCP mode requires NODE_IS_VALIDATOR to be set?

Answer 1

From the docs:

If you don’t include a NODE_SEED or set NODE_IS_VALIDATOR=true, you will still watch SCP and see all the data in the network but will not send validation messages.

Does that help?
