0PN Lab Sandbox · Digital Transparency Infrastructure

Transparency you can inspect,
before you commit.

Stand up a Transparency-by-Default baseline, trigger a notice receipt, and verify it against our reference implementation. Real artefacts, no intake form, no obligation. Controller-ID-first, standards-grounded, hash-verifiable.

Access is gated to start. Every request is acknowledged with a notice receipt, the on-ramp practices what it sells.

What you can inspect

Not assertions. Running, hash-verifiable artefacts you can open, exercise, and check.

01

Controller record (CIR)

A live controller identification record: who is accountable, the declared purposes, and the legal basis, resolvable as a did:web controller ID.

02

Notice receipt (TS 27560)

Trigger a notice and receive a standards-conformant receipt with an ID tied to the notice version. Evidence the notice happened, not a claim that it did.

03

Tamper-evident NEL chain

Inspect the notice event log: hash-linked entries where each record commits to the one before it. Confirm for yourself the sequence cannot be silently altered.

04

TPI-R measurement

A Transparency Performance Indicator reading with per-criterion findings, not one opaque grade. Re-runnable, so it can be benchmarked over time.

05

Clean AI chain (reference)

A sanitised reference example: a consent record flowing to an inference-disclosure event, the evidence that even the processor cannot read the principal's data.

Then: your own domain

Once you have access, run a read-only TPI-R capture against a domain you control and read the findings against the same criteria.

How it works

  1. 1

    Request access

    Tell us who you are and a domain you care about. We acknowledge the request with a notice receipt for the email you share, the gate itself demonstrates the product.

  2. 2

    Inspect the reference

    Open the controller record, trigger a notice, read the receipt, and verify the NEL chain is tamper-evident. See the actual outputs.

  3. 3

    Run it on your domain

    Run a read-only measurement against a domain you control and get per-criterion TPI-R findings.

  4. 4

    Decide what is next

    If it is useful, we send a scoping outline within five working days for the package that matches what you need. No obligation.

Request access

Gated to start. Free. No obligation. We acknowledge every request with a notice receipt.

We respond within five working days. Your email is used only to grant access and is itself covered by a notice receipt.
