📄️ Identity Authority (IA)
An Identity Authority (IA) is a service 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 identity or telecommunications service that an Identity Authority queries to verify user identity.
📄️ The Fallback Address
Lightning payments are push-based — the recipient must generate an invoice before the payment can occur. If Alice wants to zap Bob's Discord account but Bob doesn't own a Lightning wallet, the standard flow fails.
📄️ Verification Model
When a client application (like a wallet or a social frontend) encounters an Identity Connection (Kind 35521), it needs to verify that the connection is legitimate before displaying a "Verified" badge or enabling payments.
