Bitcoin is starting to come into its own as a digital currency, but the blockchain technology behind it could prove to be much more significant. This book takes you beyond the currency ("Blockchain 1.0") and smart contracts ("Blockchain 2.0") to demonstrate how the blockchain is in position to become the fifth disruptive computing paradigm after mainframes, PCs, the Internet, and mobile/social networking.
Author Melanie Swan, Founder of the Institute for Blockchain Studies, explains that the blockchain is essentially a public ledger with potential as a worldwide, decentralized record for the registration, inventory, and transfer of all assets—not just finances, but property and intangible assets such as votes, software, health data, and ideas.
Topics include:
Concepts, features, and functionality of Bitcoin and the blockchain
Using the blockchain for automated tracking of all digital endeavors
Enabling censorship?resistant organizational models
Creating a decentralized digital repository to verify identity
Possibility of cheaper, more efficient services traditionally provided by nations
Blockchain for science: making better use of the data-mining network
Personal health record storage, including access to one’s own genomic data
Open access academic publishing on the blockchain
