Official abstract text for this publication.
Systems and methods for space-based transactions are disclosed. A method for conducting a space-based transaction may include: (1) a first space-based device determining that it is incapable or will be incapable of providing the service; (2) the first space-based device identifying a second space-based device; (3) the first space-based device requesting capability information for the second space-based device; (4) the first space-based device that the second space-based device is capable of providing the service based on the capability information; and (5) the first space-based device executing a transaction with the second space-based device, wherein the first space-based device pays the second space-based device for the service by transferring payment from an electronic wallet for the first space-based device to an electronic wallet for the second space-based device on the distributed ledger network, and the second space-based device provides the service to the user.

What is claimed is: 1. A method for conducting space-based foreign exchange transactions, comprising: determining, by a first space-based user and using a first space-based user computer processor on a first space-based device, that a foreign exchange transaction is needed; identifying, by the first space-based user and using the first space-based user computer processor, a second space-based user as a counterparty to the foreign exchange transaction, wherein the second space-based user is associated with a second space-based device; agreeing, by the first space-based user and using the first space-based user computer processor, to a foreign exchange rate with the second space-based user; determining, by the first space-based user and using the first space-based user computer processor, that the first space-based user and the second space-based user are out of contact with a distributed ledger network; writing, by the first space-based user and using the first space-based user computer processor, the foreign exchange transaction and the foreign exchange rate to a side chain for the distributed ledger network in response to the first space-based user and the second space-based user being out of contact with the distributed ledger network, wherein a smart contract executes the foreign exchange transaction using the foreign exchange rate; and writing, by the first space-based user and using the first space-based user computer processor, a net of the foreign exchange transaction to the distributed ledger network in response to contact between the first space-based user and the distributed ledger network is re-established, wherein the smart contract updates balances in a first space-based user electronic wallet and a second space-based user electronic wallet. 2. The method of claim 1 , wherein the foreign exchange transaction is associated with a pending or potential transaction with the second space-based user. 3. The method of claim 1 , wherein the foreign exchange transaction is associated with a pending or potential transaction with a third space-based user. 4. The method of claim 1 , wherein the foreign exchange transaction is for stablecoins in a first currency for stablecoins in a second currency. 5. The method of claim 1 , wherein the foreign exchange rate is retrieved from a space-based oracle. 6. The method of claim 1 , wherein the foreign exchange rate is programmatically determined. 7. The method of claim 1 , wherein the foreign exchange rate is based on a bilateral agreement between the first space-based user and the second space-based user. 8. The method of claim 1 , wherein the first space-based device and/or the second space-based device are satellites. 9. The method of claim 1 , further comprising: transferring, by the first space-based user and using the first space-based user computer processor, a balance of the first space-based user electronic wallet to an Earth-based user electronic wallet. 10. A non-transitory computer readable storage medium, including instructions stored thereon, which when read and executed by one or more computer processors in a first space-based device, cause the one or more computer processors to perform steps comprising: determining that a foreign exchange transaction is needed; identifying a second space-based user as a counterparty to the foreign exchange transaction, wherein the second space-based user is associated with a second space-based device; agreeing to a foreign exchange rate with the second space-based user; determining that the first space-based user and the second space-based user are out of contact with a distributed ledger network; writing the foreign exchange transaction and the foreign exchange rate to a side chain for the distributed ledger network in response to the first space-based user and the second space-based user being out of contact with the distributed ledger network, wherein a smart contract executes the foreign exchange transaction using the foreign exchange rate; and writing a net of the foreign exchange transaction to the distributed ledger network in response to contact between the first space-based user and the distributed ledger network is re-established, wherein the smart contract updates balances in a first space-based user electronic wallet and a second space-based user electronic wallet. 11. The non-transitory computer readable storage medium of claim 10 , wherein the foreign exchange transaction is associated with a pending or potential transaction with the second space-based user. 12. The non-transitory computer readable storage medium of claim 10 , wherein the foreign exchange transaction is associated with a pending or potential transaction with a third space-based user. 13. The non-transitory computer readable storage medium of claim 10 , wherein the foreign exchange transaction is for stablecoins in a first currency for stablecoins in a second currency. 14. The non-transitory computer readable storage medium of claim 10 , wherein the foreign exchange rate is retrieved from a space-based oracle. 15. The non-transitory computer readable storage medium of claim 10 , wherein the foreign exchange rate is programmatically determined. 16. The non-transitory computer readable storage medium of claim 10 , wherein the foreign exchange rate is based on a bilateral agreement with the second space-based user. 17. The non-transitory computer readable storage medium of claim 10 , wherein the first space-based device and/or the second space-based device are satellites. 18. The non-transitory computer readable storage medium of claim 10 , further including instructions stored thereon, which when read and executed by one or more computer processors in a first space-based device, cause the one or more computer processors to perform steps comprising: transferring a balance of the first space-based user electronic wallet to an Earth-based user electronic wallet.
