NightPass Dey Test Private EU Battery Passports for Midnight

ODATANO’s NightPass dey run as public demo for Midnight’s preproduction network. Visitor fit create test battery passport, anchor record of im data and verify claim without to see the confidential value behind am. Midnight showcase the early Build Club project for July. The practical target na the EU battery passport requirement, wey go apply to EV batteries, batteries for light means of transport and industrial batteries above 2 kWh wey dem place for market from February 18, 2027.

From Battery Data to a Verifiable Claim

NightPass dey designed to give consumers, recyclers and authorities different views of the same battery passport according to their access rights. The underlying dataset go remain offchain, while cryptographic hash and verification records go dey anchored for Midnight.

The public demo dey carry user go through the process. E dey register passport identifier, e dey anchor the passport record and e dey submit zero-knowledge proof. ODATANO’s published example dey verify say battery carbon footprint dey below specified threshold without to display the value wey dem use take generate the proof. The completed passport get QR code, and people fit inspect im record and claim for public explorer.

ODATANO still describe versioned passport wey dem fit update as battery dey move through im lifecycle. The documented preproduction example dey follow battery through updated records, repurposing and transfer to new operator.

Dis one matter because the passport suppose remain useful after the initial sale, including during second-life use and eventual recycling.

EU Rules Set Limits on What Stays Private

The EU requirement pass just to attach QR code to battery. For August, the European Commission publish guidance wey map 71 passport data points and identify which ones apply to different battery categories from February 2027.

Some information must dey publicly accessible, including applicable details about battery chemistry, carbon footprint and recycled content. Other information, like detailed composition wey dem need for dismantling, go dey available under restricted access. NightPass’s zero-knowledge proofs fit support claims wey involve sensitive underlying data, but dem no fit replace disclosures wey the regulation require producers to make public.

The project recycled-cobalt example still get separate deadline. The 16% minimum recycled cobalt share for covered EV and industrial batteries go begin for August 2031. E no be condition wey go take effect with the battery passport requirement for February 2027.

A Midnight Demo With an Enterprise Path to Prove

NightPass dey extend ODATANO’s work wey connect blockchain functions to enterprise software. Im Cardano tools dey address business-system integration; NightPass dey use separate Midnight component for private attestations.

ODATANO describe route to connect passport creation to SAP workflows, but the publicly accessible NightPass experience still remain demo wey dey use Midnight Preprod.

Dem never announce any production deployment with battery manufacturer. Wetin users fit test today dey specific: passport identifier, anchored record, QR code and verifiable claim wey hide the underlying value. Commercial deployment go need connect that process to manufacturer actual battery data while e deliver every public and restricted field wey the EU passport require.
