For all of the above reasons, I think this book should be required reading for basic economics classesYou may have noticed and ignored the phrase 'blockchain' as a fad, buzzword or even technological jargon. Yet I think blockchain is a technical breakthrough that will have far-reaching consequences that will not only disrupt the financial sector but also many other companies and industries.A blockchain is a distributed network, which ensures that the data base storage devices aren't all connected to a single server. It preserves an the inventory of ordered documents, which are called blocks. Any block has a timestamp and a connexion to an earlier block. Users can only change blockchain pieces they "own" by providing the private keys needed to write to the register. Blockchain may answer this philosophic problem of AI. Blockchain ledgers decentralise data access and processing power while also keeping data and services accessible to the broader network.
