“The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value,” Don & Alex Tapscott, authors of Blockchain Revolution (2016). In simple terms, Blockchain ledger is digital, distributed and decentralized. So, how does the blockchain technology work? As per the blockchain definition, it records transactions across a global network of computers where the information is highly secure. As the name suggests, blockchain is nothing but a linear chain of blocks that holds information of transactions taking place over the web. Every block contains data in the form of coding that is organized in a chronological manner.
