Japanese electronics giant Sony has filed two patents for boosting blockchain-based ecosystems, according to filings 20180218027 and 20180219686 published by the U.S. Patent and Trademarks Office (USPTO) Aug. 2

In the second patent "Device and System," Sony proposes a way of maintaining a blockchain by multiple virtual nodes, suggesting a mechanism of accessing the distributed ledger via at least one of these nodes.
By incorporating virtual nodes, Sony intends to ensure the integrity of the blockchain in cases “where the number of devices is small or becomes small;” for example, if a number of devices went down.
Also in 2017, Sony partnered with tech giant IBM to develop an educational platform based on blockchain to provide secure sharing of student records
