Kaspa Kinesis Transport Protocol (KKTP)

The Kaspa Kinesis Transport Protocol (KKTP) is a serverless, CGNAT-compatible secure messaging protocol that uses the Kaspa BlockDAG as a decentralized mailbox for peer discovery, key agreement, and encrypted message relay. KKTP enables secure, replay-protected, and publicly verifiable communication between peers without STUN/TURN, centralized servers, or direct IP connectivity. This document specifies the protocol, data structures, cryptographic primitives, security properties, and operational considerations for KKTP.
