Dfinity is Switzerland based non-profit scientific research organization with a plan to better the use and functionality of the internet. Right now most of the data circulating on the internet is owned by the big tech companies as they, the way things are right now have created an oligopoly. Basically these companies have almost made the internet their private possession, they are just lending its services out to make more profit for themselves. If you have Googled something more than twice in a day, you have probably started seeing ads about it anytime you are browsing the internet. The Dfinity Foundation believes that there is a better way to use the internet, one which can benefit everyone included and that is why they have launched a decentralized network they have called the Internet Computer with its own native ICP token.
