Update on BSVKey's custody layer for deep space networks.
Our signed custody receipts now pass end to end on all three major open DTN (delay-tolerant networking) systems: NASA's HDTN, JPL's ION and D3TN's uD3TN. They also pass across a mixed chain, where data moves from one of these systems into another and back. In every run the network held our data through a scheduled outage, and every piece verified when it arrived.
New this week:
A test at real Earth to Moon light time: 1.3 seconds each way, with a full blackout partway through
A ground station kit that signs what a station receives, with no change to the spacecraft
A C version for flight computers that matches our published signatures byte for byte, in about 11 KB
Proof of delivery, proof of outage and proof of payment, anchored on BSV.
