📄️ Identity Authority (IA)
An Identity Authority (IA) is a service in the Zapf ecosystem that verifies a user's ownership of a Legacy Identity Provider (LIDP) account and issues cryptographic attestations proving that ownership.
📄️ Legacy Identity Providers (LIDP)
A Legacy Identity Provider (LIDP) is any traditional Web2 or telecommunications service that an Identity Authority queries to verify user identity.
📄️ The Fallback Address
To achieve the goal of "Zapping Anyone, Anywhere," Zapf must solve a fundamental UX problem: Lightning payments are push-based and require the recipient to generate an invoice before the payment can occur.
📄️ Verification Model
When a client application (like a wallet or a social frontend) encounters a Zapf Identity Connection (Kind 35521), it needs to verify that the connection is legitimate before displaying a "Verified" badge or enabling payments.
