The gossip model and NIP-89 share the same core principle: dynamic discovery. In the gossip model, clients find users by following their published relay lists, connecting to the minimum necessary relays to reach everyone you follow. Similarly, NIP-89 enables discovery of applications (including DVMs) that handle specific event kinds, ensuring smooth cross-client interactions. Both eliminate centralized gatekeepers by letting users publish their preferences for others to find - whether it's relays or application handlers.
