QUIC Identity Protocol

This document specifies QUIP (QUIC Identity Protocol), a federated application protocol providing portable cryptographic identity, verifiable server trust, deterministic state synchronization, and built-in accountability. QUIP runs over QUIC (RFC 9000) and uses a strict deterministic CBOR profile (QUIP-CBOR). Three conformance profiles are defined: Basic (messaging), Documents (content addressing), and Media (real-time transport). The protocol enables users to own a portable NodeId independent of service providers, servers to authenticate via DANE+DNSSEC with deployable fallback modes, and peers to detect and throttle misbehavior through signed violation receipts propagated via gossip.
