Global resource locator tag with blockchain
The present disclosure relates to a global resource locator tag and methods of using the same. A semiconductor chip can include a processor and a micro sized timing device. The semiconductor chip can generate a timing signal. The global resource locator tag can include a blockchain and a memory in logical communication with the processor. The processor can determine a cryptographic hash of a previous block of events in the blockchain and determine a respective inventory status of nearby labels. A data set may be compiled with the respective inventory status of nearby labels and a cryptographic hash of a previous block.
1 . A global resource locator tag configured to be affixed to an article comprising:
a processor;
a micro-sized timing device generating a timing sequence;
a memory in logical communication with the processor, said memory storing a blockchain comprising a previous block and a current block, and executable software, executable upon command to configure the processor to:
designate a nonce comprising a random number;
determine a cryptographic hash of the previous block comprising events in the blockchain and based upon the nonce;
determine a respective inventory status of multiple labels;
generate a data set with the respective inventory status of each of the multiple labels and the cryptographic hash of the previous block; and
record a next event in a next block of the blockchain, wherein the next event includes the data set.
