It is said that science precedes products by several decades While we are today talking about the Blockchain revolution, let's talk about the man who built the concept of bitcoin. David Chaum. As we know him was a professor who created concept of vault system in 1979 during his doctorate.
Infact he held the first annual crypto and cryptology conference, called 'CRYPTO' back in 1980.
He introduced the concept digital cash on basis of blind signature and group signatures, a form of basic decentralised ledger which is the basis of Blockchain today..
He was so ahead of his time and i think this guy does deserve respect for being the father of Blockchain as i believe he is known
Leave stories for another day, we have many people on list eho has in one way or the other contributed to the development of bitcoin or had impact of oast history on building such technology before time but what we consider is the successful one, now how do you identify which was successful? those who have results to show forth backing up their research and invesntions of which Satoshi Nakamoto is known for life whenever we are talking about who created bitcoin, also if you consider the cypherpunk Hal Finney of blessed memories, he has done alot in the world of cryptography and the likes to an extent that many mistook him for Satoshi but history always had it that Satoshi invented bitcoin as well.
