Blockchain may be the least well known, but it is definitely poised to impact data centers in the coming year. Blockchain is the technology underlying Bitcoin, and some analysts suggest its potential enterprise uses could far exceed its helpfulness in tracking digital currency.
Blockchain is a distributed database that is used to record an ever-growing list of transactions. It doesn't require any permission to access it, but it's nearly impossible to tamper with the data it holds. In other words, everyone can see what is written there, but no one can erase or change it.
In the future, Blockchain could be used to track many different kinds of data, to speed and secure financial transactions, or even to prevent voter fraud.
