SONAR: Statistical Observation Network for Attestation and Reach (draft-ramadan-mboned-sonar-01)

November 1, 2025

An IETF Internet-Draft specifying a protocol for verifiable multicast delivery claims without trusted intermediaries. It combines O(1) IP multicast efficiency, cryptoeconomic accountability, and real-time multicast authentication. The protocol separates content authentication from coverage verification using statistical sampling and zkSNARK proof aggregation for scalability.
