Spanish Telco Telefonica Hints at Blockchain Role in Data Tracking

Spanish broadband and telecommunications provider Telefonica may be looking to apply blockchain as a way to cryptographically verify data, according to newly released documents. On Oct. 12, the U.S. Patent and Trademark Office (USPTO) published an application for a "Method to Assure Correct Data Traversal Through a Particular Path of a Network." The document outlines a way to transfer data from one point to another using a specific path through a Service Function Chain (SFC). The patent also describes how a blockchain could be used to track the data to ensure it follows the correct path and arrives at the proper endpoint, thus improving the SFC's reliability.
