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 called.
