By hosting a knot.

You may ask, well, that's like hosting forgejo or any other git server, where is the federation?

Tangled uses a protocol. So knots would adhere to that protocol allowing to pull from any upstream.

That's my understanding of federation. not saying tangled will go as far as figuring out discovery across their cloud hosted knots and self hosted infra. But that can be done, and claiming to be able to pulling from any repo with a single identy would imply just that.
