Blockchain Revolution: How the Technology Behind Bitcoin Is Changing Money, Business, and the World

by Don Tapscott

Imagine instead of the centralized company Airbnb, a distributed application—call it blockchain Airbnb or bAirbnb—essentially a cooperative owned by its members. When a renter wants to find a listing, the bAirbnb software scans the blockchain for all the listings and filters and displays those that meet her criteria. Because the network creates a record of the transaction on the blockchain, a positive user review improves their respective reputations and establishes their identities—now without an intermediary. Says Vitalik Buterin, founder of the Ethereum blockchain: “Whereas most technologies tend to automate workers on the periphery doing menial tasks, blockchains automate away the center. Instead of putting the taxi driver out of a job, blockchain puts Uber out of a job and lets the taxi drivers work with the customer directly.”
