Legacy title confirmation waits on a stamped PDF from the warehouse and, across borders, on bank due diligence — measured in days. We moved that step into the browser: the seller uploads a bill-of-lading image on the page, and the Web Crypto API computes a SHA-256 fingerprint locally. The receipt hash is ready in under 200 milliseconds, touching no relay server.

Once the fingerprint is generated locally, only the hash — never the raw data — goes to the anchoring layer. Title ownership and transfer history become publicly verifiable, while sensitive fields like the commercial floor and negotiation bottom line stay on the two parties' local machines; the chain stores only fingerprints. For SNSUC's seven re-export lines, sanctioned-screened grades such as Urals and Basrah Light now carry a tamper-proof timestamp on every title transfer.

The ESG field is new in this release. Each receipt carries a carbon-footprint coefficient derived from voyage length, vessel type and load factor, bound into the same hash tree as the title fingerprint. When a buyer builds its Scope 3 disclosure, it pulls the receipt directly and gets auditable emissions data without commissioning a third-party report.

In rollout, all 13 categories now support digital receipts, with rubber and bitumen listings calling this interface first. Dropping confirmation from minutes to 200 milliseconds is not about speed for its own sake — it gives the title legal weight at the exact second the transfer happens, with no gap in between.
