Why it matters

Why signed proof matters

Three things that happen to real satellite data, and how a signed receipt turns an argument into a one-minute check.

The pass nobody can prove missed passes

Tue 14 Oct · 03:12 UTC
Pass scheduled. Customer paid for it.
Same pass
... Nothing came down. Moving on.
Six months later · without proof
Did our pass on the 14th happen? The insurer wants proof. Uh... trust us?
With signed pass records
PASS 14 OCT 03:12 · SCHEDULED GAP: NO SIGNAL · STATION SIGNED "I can check that myself. Done."

A silent pass becomes a dated, signed gap record. The customer still relies on the station's word, but now it was given on the day, before anyone had a reason to shade it. Six months later, nobody's memory is in play.

The bit that flipped storage corruption

Reception
SEALED 03:13 25 frames land. Each gets a fingerprint.
Months in storage
0110 1001 0110 1011 Zap. One bit flips. Disks, cables, cosmic rays.
Without a seal
Why is there a stripe in my image? It was fine... maybe?
With a seal at reception
CHANGED: pass_15123507/ data_..._19-21-03 · drift Caught, named, re-fetched from the source. The record still shows it happened.

Every product is sealed the moment it lands. Any later change, even one bit, is caught and named down to the file. This is from a real run on live SatNOGS data.

Whose fault was it? hand-offs between operators

The chain
STATION A NETWORK B CUSTOMER 412 frames, three hands.
Half is missing
Half my data is missing! 206 frames. I paid for 412.
Without receipts
Station A: we sent all of it. Network B: we never got it. Weeks of email.
With signed hand-offs
A SIGNED: 412 B SIGNED: 206 ! The gap is between A and B. Network B: "Oh. That's us." SETTLED IN ONE MINUTE

Each hand-off gets a signed receipt with the exact data it held. The loss shows up where it happened, so nobody has to argue.

How it works: each receipt holds a fingerprint (SHA-256) and a signature. Batches can be timestamped on Bitcoin BTC or Bitcoin BSV. Try it in your browser or ask about a ground station pilot.

More strips: insurance and six industries (pharma, cargo, aviation, vehicles, robotics, finance) and weather triggers.
