Three innovations disclosed as prior art:
(1) Mesh-relayed Cashu ecash payments via ESP-NOW/BLE with autonomous
supply chain settlement — offline Bitcoin commerce across multiple hops,
merchant-to-supplier settlement without banking infrastructure
(2) BLE beacon-driven merchant discovery with offline NFC payment
completion — full discovery-to-payment flow with no internet on either device
(3) Agent-native vending machines as sovereign Nostr participants —
machines with their own keypair, publishing inventory, accepting orders,
processing payments via Cashu, Lightning, and zaps
All innovations placed in the public domain. No party may obtain
exclusive patent rights over these methods.
