Blockchain has the potential to revolutionize financial and cyber security. It provides an incorruptible digital ledger that can record transactions of value in a way that is verifiable and accessible to anyone. Blockchain uses a distributed network of nodes that jointly manage a database without a central authority. Information on the blockchain is stored across this network through a linked chain of blocks secured by cryptography. The first blockchain was developed for the cryptocurrency Bitcoin in 2009. Blockchain offers benefits like speed, low costs, decentralization, secure payments, and transparency. It could enhance concepts like globalism, security, and democracy through applications on a transparent, secure global platform.
