Phosra Spec / Capability

PCSS v1.0 — Draft

Phosra Notary

Cryptographically signed events and regulatory reporting.

What Notary does

One signed receipts layer for every regulator request.

When a state AG, the FTC, or a plaintiff’s attorney asks “show me every block enforced for jurisdiction X under provision Y in the last 90 days,” most platforms can’t answer. Their enforcement events live in a dozen logs across a dozen systems with no chain-of-custody, no signature, and no statute citation.

Notary is the receipts layer. Every Phosra enforcement decision — every block, every consent grant, every age signal verification, every CSAM detection — is cryptographically signed at the moment it happens, stamped with the statute citation that triggered it, and held in a tamper-evident append-only log. State AG submission portals, NCMEC’s CyberTipline, and the EU eSafety commission reporting channels read directly from Notary.

A platform’s response to a regulator goes from a six-week subpoena exercise to a 30-second query. The chain-of-custody required for litigation evidence (CA AB 2, NY S8102) is built into every event by default.

How partners plug in

Notary is a socket. Signed events flow out. Regulator portals read directly.

These are the downstream regulator submission channels and attestation frameworks Notary writes to — either shipping today, in conversation with a partner, or pending an upstream pilot.

Standards & laws

What Notary does for each statute.

  • 18 U.S.C. § 2258A (CSAM mandatory reporting) — produces the signed event submission package.
  • CA AB 1700 (eSafety commissioner reporting) — auto-routes to the state reporting channel.
  • CA AB 2 + NY S8102 (platform liability evidence) — captures and preserves harm-event traces.
  • FTC consent decrees + Disney 2025 settlement — produces the audit-trail compliance report.
  • EU DSA Art. 24 (transparency reporting) — generates the periodic transparency dump.
  • Australia eSafety Commissioner (BOSE Codes) — formats reports per the Australian schema.
  • 18 U.S.C. § 2258B — preserves CSAM-detection chain-of-custody for prosecution.

Conformance

Adopter Tier 1 certification.

To ship Notary-conformance for an Adopter Tier 1 certification, your implementation must pass the Notary suite. Test count is [draft] coming Q3 2026. The suite covers cryptographic signature integrity, statute-citation correctness, append-only log tamper-evidence, and regulator-portal submission interop.

We are co-authoring the suite with our design partners. If you want a seat at the table while the bar is being set, reach out.
