Based on the public application to US Patent and Trademark Office on Thursday where Blockchain technology was used to certify timestamps as a program combined with Public Key Infrastructure (PKI) tools.
Apple’s application describes three possible methods for establishing timestamps, with one of these scenarios centering on a Blockchain platform. There is a use case in question where data stored involves tying a piece of information to a particular transaction on a Blockchain, establishing the state of that data at a particular point in time.
The program would generate a block containing a timestamp, with every subsequent block being added as miners verify each transaction conducted on the chain. This system is part of what Apple is calling a “multi-check architecture,” meaning that another system would confirm the timestamp after the block is generated but before it is added to the chain…
