Satoshi Nakamoto, whether he's an individual or a group of people I'm not quite sure. But one thing is certain, he revolutionized the world with the invention of Bitcoin and blockchain. Blockchain is a wonderful technology which gives internet users and businesses the ability to create value and authenticate digital information. This technology will definitely play a great role in determining how data is accessed in future, also many companies are exploring its potential and working on adopting it to run their businesses.
An example is Mastercard who recently announced that they are launching their own blockchain network to enable partner banks and merchants to make cross-border payments faster and more securely.
