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 This book is part of an ongoing O’Reilly series. Mastering Bitcoin: Unlocking Digital Crypto-Currencies introduces Bitcoin and describes the technology behind Bitcoin and the blockchain. Blockchain: Blueprint for a New Economy considers theoretical, philosophical, and societal impact of cryptocurrencies and blockchain technologies.
Before we start with a formal introduction to blockchain, let us take you for a moment to a possible future that should realize sooner than we expect. You are on a vacation outside your home country, at a shopping mall and receive a notification saying there is a sale on luxurious watches. You haven't been to this store before. You pick up a watch and you wonder if the watch is genuine and worth the price. You start a mobile application and place it on the watch. The application recognizes the watch and displays the complete lifecycle of the watch like where it was manufactured and the GPS coordinates, where it was designed, what is the warranty period, how much custom duty you need to pay (if any) if you bring this watch back to your home country and even showing and comparing similar watches. You purchase the watch based on these details and now feel even more connected to the watch brand and establish a trust with the shopping store for selling genuine products. Let's consider a complex B2B process like an international trade finance which currently takes days to complete the trade process. If the entire workflow is automated, self regulated and equipped with enough consensus between various parties carrying out the trade, it can provide a window of opportunity for new buyers and sellers to handshake, implement and execute trade seamlessly with lot of trust and confidence. In the above scenarios that we described earlier and possibly in all our future applications, data would be a central point for businesses, consumers, and even system interaction. Now in a data-driven world, you need to establish trust and compliance between parties, you need governance, regulation and accountability through automated workflow and digital contracts rather than central authority and finally a piece of technology that can enable to realize this goal. Once these basic parameters are enabled, it opens endless opportunities to move any value (from services to digital assets) across the network in a secure and transparent way. The technology enabler that can aid in realizing this opportunity is blockchain. We view blockchain as an enabler to provide consensus on data. The consensus can be between B2B, B2C or C2C. We call blockchain an enabler, as blockchain alone will not lead to realizing the opportunities we talked about earlier.The combinatorial power of blockchain, smart contracts, and technologies like IoT & Artificial Intelligence would enable to deliver value-driven intelligent applications. While we described our vision, we are probably at the first generation of blockchain implementation where technologies are still evolving, and use cases are being realized. Through this book, we aim to provide a reference guide for building blockchain applications. The book comprises of three chapters. In Chapter 1, we will provide a neutral vision and architecture for blockchain, without getting into vendor specific details. In chapter 2 and 3, we will demonstrate the working of two widely used blockchain implementations - Ethereum and IBM Hyperledger Fabric respectively. To summarize, as part of the book, we will cover the following - 1. A vendor-neutral architecture for building any blockchain applications. 2. A detailed introduction to Ethereum and its core components. We will set up a local instance of Ethereum and build end-to-end application on Ethereum blockchain using a hands-on approach. At the end, we would cover topics around extension to Ethereum blockchain, integration with the external world and the future of smart contracts. 3. A detailed introduction to IBM Hyperledger Fabric and its core components. We would cover the enterprise capabilities provided by Fabric 1.0. At the end, we would set up a local instance of Fabric and build an end-to-end application on Fabric using a hands-on approach.
Take advantage of Bitcoin’s underlying technology, the blockchain, to build massively scalable, decentralized applications known as dapps. In this practical guide, author Siraj Raval explains why dapps will become more widely used—and profitable—than today’s most popular web apps. You’ll learn how the blockchain’s cryptographically stored ledger, scarce-asset model, and peer-to-peer (P2P) technology provide a more flexible, better-incentivized structure than current software models. Once you understand the theory behind dapps and what a thriving dapp ecosystem looks like, Raval shows you how to use existing tools to create a working dapp. You’ll then take a deep dive into the OpenBazaar decentralized market, and examine two case studies of successful dapps currently in use. Learn advances in distributed-system technology that make distributed data, wealth, identity, computing, and bandwidth possible Build a Twitter clone with the Go language, distributed architecture, decentralized messaging app, and peer-to-peer data store Learn about OpenBazaar’s decentralized market and its structure for supporting transactions Explore Lighthouse, a decentralized crowdfunding project that rivals sites such as Kickstarter and IndieGogo Take an in-depth look at La’Zooz, a P2P ridesharing app that transmits data directly between riders and drivers

If you're looking to get started with the Ethereum protocol-or are among the many open source developers, integrators, and system administrators already working with this platform-Mastering Ethereum is the definitive book on the topic. Authors Gavin Wood and Andreas Antonopoulos provide everything you need to know about building smart contracts and decentralized autonomous organizations on the Ethereum blockchain. By bridging the world of cloud computing, grid computing, and blockchains, Ethereum has create a massive decentralized computing platform that many people are calling a "world computer." Ethereum has also spawned a rapidly growing ecosystem of software startups vying to build decentralized applications, known as "dapps". With this practical guide, you'll learn how to create markets, store registries of debts or promises, move funds in accordance with instructions given long in the past (like a will or a futures contract), and many other things that have not been invented yet, all without a middle man or counterparty risk. Discover why IBM, Microsoft, NASDAQ, and other organizations have announced interest and/or development in this Turing-complete decentralized computing platform with Mastering Ethereum.
