The blockchain is a decentralized public ledger of all the Bitcoin transactions that have ever been executed. But blockchain technology is much more than Bitcoin, as the technologist and entrepreneur Melanie Swan demonstrates in her new book, Blockchain: Blueprint for a New Economy. Swan persuasively contends that the advent of the blockchain platform as "a universal, permanent, continuous, consensus-driven, publicly auditable, redundant, record-keeping repository" is a technological game-changer as significant as the creation of the Internet. Since it is a decentralized public ledger, the blockchain enables the trustless transfer and accurate recording of all transactions and documents.
