A passport that travels
with the product, for life.
From manufacture to recycling, a Digital Product Passport proves who made a product and that its record hasn't been tampered with — while revealing only what each party needs to see. Issued as SD-CWT, logged in a public transparency log, and verifiable by anyone.
See what a passport is — and watch it work.
A Digital Product Passport is a signed set of claims about a product. This is a simulation, not a real market — synthetic batteries move through their lifecycle while the real Go issuer (compiled to WebAssembly) issues each one, logs it, presents it, and verifies and validates it, live. The data is made up; the cryptography is genuine.
Architecture
Three actors, one transparent service.
The seller registers a passport. The buyer controls disclosure. The auditor receives only what the buyer permits — alongside a receipt proving the passport was logged.
Built on open transparency infrastructure.
Every passport is recorded in an append-only log built on Google's Certificate-Transparency lineage, and the observatory's agent runs on Gemini.
Watch the market, live.
The profile explorer streams real Digital Product Passports through their lifecycle — issued, logged, presented, verified and validated, all in your browser. No login. The full observatory (live transparency log + agent) is invite-only while we're under construction.
