I am currently developing an experimental identity protocol on top libp2p gossipsub(https://idp2p.github.io/). The protocol assumes each identity is a topic to subsribe. Whenever an identity is created, a topic should be created for that identity(per identity per topic). So you can guess there should be created a lot of topic dynamically.
I wonder if libp2p gossipsub protocol is scalable for this kind of use case.
