Blockchain, also known as distributed ledger technology, is a software protocol which allows sharing of data on a distributed, secure, and unaltered ledger which requires mutual consent.

Many other players like Alibaba and IBM have already started to file a number of blockchain-related patents and are integrating blockchain with security and other major areas of interest.
"Many blockchain use cases have been identified, but full products/services have not yet been built out and are not used in production.”, Rangan said explaining that there are a still a wide range of blockchain estimates out there, and its money-making ability is yet to be proven.
