USPTO publishes two more blockchain-related patent applications from Verisign.

The United States Patent and Trademark Office (USPTO) published two of Verisign's (NASDAQ: VRSN) blockchain-related patent applications last week.

Application 17/325687 (pdf) is for Proving Top Level Domain Name Control on a Blockchain. The abstract states:

Systems, methods, and computer products for associating a top level network identifier with a blockchain address on a blockchain enable operations that may include: obtaining, from a root network segment file, an identification of a server that stores network infrastructure records associating network identifiers under the top level network identifier with network addresses and a signature on the identification of the server; obtaining, based on a first network infrastructure record, an association of the top level network identifier with the blockchain address; obtaining information sufficient to validate a trust chain, wherein the trust chain extends from a trusted authority to the association; and sending the association and the information sufficient to validate the trust chain to an executable program on the blockchain. The trust chain may be validatable by the executable program, and the association may be storable on the blockchain by the executable program.

Verisign filed both applications on May 20, 2021. Andrew Kaizer and Swapneel Sheth are listed as inventors. Both are also listed as inventors on a blockchain patent that has already been granted.
