US10275739

1. A method, comprising: (2) (5)

reading, via a reader in communication with a blockchain, and from a tag affixed to an asset, a tag identifier associated with the asset, and a nonce value associated with a current location of the asset, wherein the tag identifier and the nonce value are stored in the tag and in locations in the blockchain;

generating, via the reader, a new nonce value associated with a transfer of the asset to a new location, the new nonce value to be stored in a location in the blockchain;

transmitting, via the reader, a request, including the tag identifier, the nonce value, and a new nonce value, to update an asset status, of the asset, stored in the blockchain;

receiving, via the reader, and from the blockchain, a validation confirmation based on the request; and

dynamically updating, via the reader, the tag with an updated asset status from the blockchain and the new nonce value from the blockchain in response to the validation confirmation.

2. The method of claim 1, wherein the validation confirmation is received responsive to transmitting the tag identifier and the nonce value as the request content. (0)

3. The method of claim 1, wherein the tag comprises a radio frequency identification (RFID) component and a memory. (1) (0)

7. A wireless tag reader in communication with a blockchain, the wireless tag reader comprising: (2) (1)

a processor configured to: read, from a tag affixed to an asset, a tag identifier associated with the asset, and a nonce value associated with a current location of the asset, wherein the tag identifier and the nonce value are stored in the tag and in locations in the blockchain;

generating, via the reader, a new nonce value associated with a transfer of the asset to a new location, the new nonce value to be stored in a location in the blockchain;

transmit a request, including the tag identifier, the nonce value, and a new nonce value, to update an asset status of the asset in the blockchain; and

dynamically update the tag with an updated asset status from the blockchain and the new nonce value from the blockchain in response to the validation confirmation.

8. The wireless tag reader of claim 7, wherein the validation confirmation is received responsive to transmitting the tag identifier and the nonce value as the request content. (0)

9. The wireless tag reader of claim 7, wherein the tag comprises a radio frequency identification (RFID) component and a memory. (1) (0)

13. A non-transitory computer readable storage medium configured to store at least one instruction that when executed by a processor, of a wireless tag reader in communication with a blockchain, causes the processor to perform: (2) (5)

reading, from a tag affixed to an asset, a tag identifier associated with the asset, and a nonce value associated with a current location of the asset, wherein the tag identifier and the nonce value are stored in the tag and in locations in the blockchain;

generating, via the reader, a new nonce value associated with a transfer of the asset to a new location, the new nonce value to be stored in a location in the blockchain;

transmitting, via the reader, a request, including the tag identifier, the nonce value, and a new nonce value, to update an asset status, of the asset, stored in the blockchain;

receiving, via the reader, and from the blockchain, a validation confirmation based on the request; and

dynamically updating, via the reader, the tag with an updated asset status from the blockchain and the new nonce value from the blockchain in response to the validation confirmation.

14. The non-transitory computer readable storage medium of claim 13, wherein the validation confirmation is received responsive to transmitting the tag identifier and the nonce value as the request content. (0)

15. The non-transitory computer readable storage medium of claim 13, wherein the tag comprises a radio frequency identification (RFID) component and a memory. (1) (0)
