In october 2008, a person / group with pseudonym “Satoshi Nakamoto” published a tectonic shifting paper on a digital currency system which was named as “Bitcoin”.

It was first of its kind peer to peer currency system with no central authority or supervision. To put it simply, it is like “torrent” of currency where every participant has a journal of transactions of everyone so no single entity can exert their control over it. The underlining technology “blockchain” is now implemented to solve various complex problems of governance.
