What is Blockchain technology? This has been the question of every citizen of this earth right after we were introduced to Bitcoin. Bitcoin is considered to be some kind of technical miracle working with the help of some magical mystery called Blockchain. To be frank, if you really wish to understand the technology behind Bitcoin, then we are on the same page. The main concept of Blockchain technology is—Trust.
