Nasdaq is looking to patent a method by which a blockchain could be used to secure records of exchange transactions.
On 6th October, the US Patent and Trademark Office (USTPO) released an application for "systems and methods of blockchain transaction recordation", originally submitted by Nasdaq on 31st March. It is attributed to Tom Fay, Nasdaq’s senior vice president of enterprise architecture, and Dominick Paniscotti, associate vice president for enterprise architecture.
Essentially, the application details an exchange system comprising digital wallets, an order book and matching engine, with a "closed blockchain" utilized as a record of transactions that is updated in real-time.
As the application details:
From there, the exchange checks the contents of the blockchain, looking for the data associated with those digital wallets. An additional backup of that information is also kept in a separate database.
The application's contents reveal that the company is largely looking to apply claims to the method of using a blockchain in an exchange environment, rather than the system itself. USTPO records show that Nasdaq originally sought a number of claims related to the tech, but that these were cancelled after the application was first filed in March.
