Pin the loss to a leg of the route
Signed handoffs with seal number and condition at every transfer show exactly where the problem started.
For shippers, freight forwarders and marine cargo insurers
When the container arrives damaged, know who owes you.
A container passes through six or more hands between origin and destination. When the cargo arrives damaged, spoiled or short, every party says it was fine when they had it, and the shipper or its insurer usually ends up paying.
The dented container shipping and cargo
Each party signs the container's seal number and condition when it takes it. The first signed "damaged" shows exactly which leg the loss belongs to.
What it costs you today
Cargo claims turn into weeks of emails, surveys and competing paperwork. Reefer spoilage is the worst case: the container's temperature log exists, but nobody can prove whose watch it happened on. Claims that cannot be pinned on anyone are paid by the shipper or its insurer, or not at all.
What changes
Reefer claims settled on data
Container temperature logs are tied to whoever held the box, using the same engine that already works for pharma.
Fewer surveys, faster payouts
Insurers get one evidence file they can check themselves, instead of rebuilding the voyage from each party's records.

How it works now shipping and cargo
Free in your browser: each party signs with its own key, the container file travels with the box, and anyone can check it. For a result signed by BSVKey and a loss split, run the paid check.
How it works
Each party signs a small record at the moment it takes responsibility. The records chain together, so a missing, edited or forged one is caught.
| Record | Signed by | Says |
|---|---|---|
| maritime.handoff/1 | the receiving party | received this container, seal number and condition, from that party |
| maritime.leg/1 | the party holding it | reefer logger fingerprint, excursions and gaps for its time (the pharma engine) |
| maritime.voyage/1 | the vessel | custody for everything aboard, signed once per satellite contact |
All records use canonical JSON, a SHA-256 fingerprint and an Ed25519 signature, the same primitives proven in our space custody work.
A real run
A refrigerated container, 0 to 4 C, 120-minute budget, seven parties from grower to importer Vessel reports: 43 satellite contacts, one signature each over all 1,800 boxes aboard Verified from the raw reefer CSV and the vessel's reports: PASS excursion terminal-dest 150 min, peak 8.6 C logger gap trucker-dest 45 min contact blackout vessel 30 h without contact (no fault) 195 of 120 minutes allowed: outturn "claim" Liable: terminal-dest 76.9%, trucker-dest 23.1% of spoilage minutes Container aboard at contact 10: true Packing-list line 8 in this container: true Tampering: terminal deletes its warm rows from the reefer export caught terminal re-signs a clean leg for itself caught terminal withholds its leg entirely no gain, still liable vessel rewrites a contact report afterwards caught terminal re-signs its handoff with a different seal caught packing list swapped at the destination terminal caught importer's outturn forged, or names the wrong party caught
The vessel's 30 hours out of contact is recorded but is nobody's fault: the reefer log covers it. The unplugged reefer at the destination terminal is what turned the box into a claim.
Where it stands
- Status. Working today, free: sign your own records and check them in your browser with the sign-and-check app, built from the open-source code (Apache-2.0) with automated tests. The reefer analysis is the working pharma engine. A design partner helps us connect it to your own systems and devices.
- For insurers. Marine cargo insurers learn where the loss happened and who held the cargo then. Reefer claims can be allocated by attributed time, as in pharma.
- Scope. The software records only what the parties choose to record. Sanctions and export rules still apply to cargoes and routes.
- Billing. Pay as you go in US dollars or Bitcoin BSV, with prepaid credits or by invoice. Paying in dollars needs no cryptocurrency (how billing works, start now).
