Xerox — famed for its eponymous printing and digital duplicating appliances — 1st filed the patent earlier in Aug. 2017. The patent describes a blockchain-based system for the secure recording of revisions created to electronic documents.
The technology offered by Xerox will purportedly find whether or not a file has been altered and tracks the history of changes created. Owing to the decentralised verification mechanism, the system so becomes immune to tampering, the filing states.

Major tech and electronics corporations have filed a slew of patent applications for varied proprietary iterations and applications of blockchain technology. A Sept. report stated that IBM had filed additional blockchain-related patent applications than the other company at the time of publication.
IBM has filed over ninety blockchain patents, the foremost recent of that aims to use blockchain technology to assist scientific research project and provide a record of its results.
