The idea of blockchains was born in 1991. It was in 2009, when an anonymous person under the pseudonym of Santoshi Nakamoto, decided to use blockchains to create digital cryptocurrency Bitcoin, that these chains became essential as a tool for people to invest and transfer funds in the form of cryptocurrencies. Not limited to cryptocurrencies and the financial industry, blockchains are also utilised across the healthcare, media, real estate industries, as well as government bodies.
