I think I have a vague idea of how the IPNS pubsub resolution works. It appears to create a room where the publisher sends updates to the IPNS record so that subscribers will get updates quickly. I’m assuming that the room name is somehow included in the IPNS record so someone knows where to listen for updates.
What I’m not sure about is how this gets started. Is the initial resolution standard IPNS? If so is it correct that the initial resolution may be slow and IPNS pubsub would only be fast for updates?
