Basics of Blockchains and the Illustration of Village Beta

Blockchain has been pushed into the limelight by a new and controversial form of digital currency called Bitcoin. The success stories of early Bitcoin investors and the launch of Ethereum, a platform allowing the creation of decentralized applications, brought blockchain and cryptocurrencies to the frontier where decision-makers and executives started to pay attention to this emerging piece of technology. Many curious persons began to wonder how it could help them in their personal or professional enterprises, leading them to believe that this innovation could be an appropriate answer to their business issues. The Economist, on October 31, 2015, published the first well-known article about blockchain (https://www.economist.com/printedition/covers/2015-10-29/ap-e-eu-la-me-na-uk).
