It's the same model, an account system using a local database.

Our thesis is everyone is trust smuggling anyway, so we may as well make tooling that's transparent and reliable for that. With this people can make those trust trade-offs hyper-locally, community/business/family settings etc.

Also we've made the whole thing nostr native, the accounts are Nostr based and the API works over Nostr... this solves the networking issues with self-hosted and allows us to get wild with UX and Enterprise-class features on top of it.

For example, inviting friends or family to your node is just sending them a link with your nodes nprofile encoded, or use a lightning address for debits not just payments.
