Field notes on synthetic-media defense: provenance, detection, decentralized validator networks, and the dfpn threat model.https://dfpn.cryptuon.com/en-ushttps://dfpn.cryptuon.com/blog/reading-dfpn-threat-model/https://dfpn.cryptuon.com/blog/reading-dfpn-threat-model/A close read of the dfpn threat model. Six adversary classes, the protocol mitigations paired with each, the trust assumptions named explicitly, and the things dfpn deliberately does not try to do.Tue, 26 May 2026 00:00:00 GMThttps://dfpn.cryptuon.com/blog/why-decentralized-validator-network/https://dfpn.cryptuon.com/blog/why-decentralized-validator-network/Detection-as-a-service from a single vendor is brittle for civic infrastructure. A decentralized validator network gives you detector diversity, censorship resistance, and an audit trail that no operator can quietly rewrite.Tue, 19 May 2026 00:00:00 GMThttps://dfpn.cryptuon.com/blog/provenance-vs-detection/https://dfpn.cryptuon.com/blog/provenance-vs-detection/Provenance and detection sit at different points in a media lifecycle. Provenance answers 'where did this come from?' at capture time; detection answers 'does this look manipulated?' after the fact. Both are needed; neither is enough on its own.Tue, 12 May 2026 00:00:00 GMT
