Abstract

A system for transacting in an environment with intermittent connectivity via a network backbone to a blockchain. A merchant device transmits a set of credentials for an ad hoc network to a buyer device and establishes a private peer-to-peer ad hoc network connection with the buyer device. It then conducts a transaction with the buyer device via the private peer-to-peer ad hoc network. If no network connection is available to a transaction blockchain, the merchant device stores a record of the transaction until such network becomes available and later sends the record of the transaction to the transaction blockchain.

Claims (17)

1 . A system for transacting in an environment with intermittent connectivity via a network backbone to a blockchain, comprising:

a merchant device comprising at least a processor, a memory, and programming instructions stored in the memory and operable on the processor, wherein the programming instructions, when operating on the processor, cause the processor to:

transmit a set of credentials for an ad hoc network to a buyer device;

establish a private peer-to-peer ad hoc network connection with the buyer device;

conduct a transaction with the buyer device via the private peer-to-peer ad hoc network;

if no network connection is available to a transaction blockchain, store a record of the transaction until such network becomes available; and

when feasible, send the record of the transaction to the transaction blockchain.

2 . The system of claim 1 , wherein each time the merchant device encounters another known, trusted device on a peer-to-peer network, it transmits an encrypted copy of each recorded transaction that has not been transmitted to the transaction blockchain to the known, trusted device for transmission to the transaction blockchain by the known, trusted device.

3 . The system of claim 1 , wherein either or both of the buyer and merchant devices are antitamper-hardened devices.

4 . A method for transacting in an environment with intermittent connectivity via a network backbone to a blockchain, comprising the steps of:

transmitting, from a merchant device comprising at least a processor, a memory, and programming instructions stored in the memory and operable on the processor, a set of credentials for an ad hoc network to a buyer device;

establishing a private peer-to-peer ad hoc network connection between the merchant device and the buyer device;

conducting a transaction with the buyer device via the private peer-to-peer ad hoc network;

if no network connection is available to a transaction blockchain, storing a record of the transaction until such network becomes available; and

when feasible, sending the record of the transaction to the transaction blockchain.

5 . The method of claim 4 , wherein each time the merchant device encounters another known, trusted device on a peer-to-peer network, it transmits an encrypted copy of each recorded transaction that has not been transmitted to the transaction blockchain to the known, trusted device for transmission to the transaction blockchain by the known, trusted device.

6 . The method of claim 4 , wherein either or both of the buyer and merchant devices are antitamper-hardened devices.
