Know what went in. Prove what came out. Data with receipts. Everything else is entropy. Every data operation in DRM3 produces an attestation. The party that performed the work states what was done, what data went in, what came out, and why, and cryptographically signs it. The attestation is the claim and the proof in one act. Signed with Ed25519, chained to every attestation before and after it. Today, DRM3 Labs operates 30 signing keys derived from a single root, attesting data from 23 government and public sources, 6,700+ curated news feeds processing millions of articles per year, and 10,000+ scanned domains. Signals fetches from 23 government and public sources. Connor scans 10,000+ domains. News RAG processes 6,700+ feeds. These are substrate APIs. Their outputs aggregate into composite data layers, get harmonized across sources, then synthesized by AI into structured intelligence. That intelligence feeds content generation. Each layer signs what it produces. The provenance chain runs from the raw API call through aggregation, harmonization, synthesis, and generation to the final output. Protocol requirements: Sovereignty, Privacy, Equitability, Transparency. The protocol enforces all four simultaneously or it enforces none of them. The EU AI Act enforcement deadline is August 2026. DRM3 is the infrastructure layer where open data becomes verifiable data. Provenance as an architectural property, not a reporting burden.
