NIP-70: Protected events
A protected event may only be published by its authenticated author, when a relay supports accepting it.
Implementation
The production relay advertises NIP-70. The Coax relay has AUTH plumbing but not this complete protected-event policy.
Example
This demo reads a frozen public NIP-11 capability document. It does not execute this NIP on a relay.
What remains
AUTH alone does not implement NIP-70. The event author must be bound to the authenticated connection under the protected-event rules.
