Cryptocurrencies might be interesting, and there is even profit to be had if you do your own mining, but this pales in comparison to the numerous ways in which blockchain technology will change the way information is shared across the world.
There is no doubt that blockchain technology will become a central part of our lives over the next ten to fifteen years. Soon you will start to see large financial institutions use the technology to revamp the way that they create and are held to contracts. Blockchain will be massively disruptive for payment processors and credit cards. It is a very real possibility that not too long in the future a government will adopt blockchain as the underpinning of their official currency.
Blockchain has truly moved out of the realm of interesting and into the spotlight as a practical, powerful and necessary tool to facilitate information sharing in the twenty first century.
