OP token and Super chain Architecture

As OP has built the Superchain architecture, do entities say Coinbase with Base have to stake OP tokens as validators for their network?

I don’t think OP stack requires consensus. So, there is no need to stake OP to be a validator in these networks.

As a note, the OP Documentation on the Super Chain doesn’t seem to work.

None of the links for “Building OP Stack Rollups” seem to work. Nor does the link to editing on Github.
