The history of blockchain doesn't go back too far, it does go back to the early 90s when a two physicists, Stuart Haber & W Scott Stornetta, were trying to solve a big problem, how to keep the past secure, and keep digital information safe and resistant to tampering? 

They published their first paper to outline the use of a chain of cryptographically secured blocks to preserve the integrity of past information and protect it. This system is commonly known as ledgers in the society.
