Blockchain is the popular name given to the exciting, evolving world of distributed ledger technology (DLT). Blockchains offer equitable and secure access to data, as well as transparency and immutability. Organisations can decide to use blockchain to upgrade whatever ledgers they are currently deploying (for example, relational databases, spreadsheets and cumbersome operating models) for their data and technology stack in terms of books and records, transactions, storage, production services and in many other areas. This book describes the applied use of blockchain technology in the enterprise world. Written by two expert practitioners in the field, the book is in two main parts: (1) an introduction to the history of, and a critical context explainer about, the emergence of blockchain written in natural language and providing a tour of the features, functionality and challenges of blockchain and DLT; and (2) a series of six applied organisational use cases in (i) trade finance, (ii) healthcare, (iii) retail savings & investments, (iv) real estate, (v) central bank digital currencies (CBDC) and (vi) fund management that offer the reader a straightforward, easy-to-read comparison between 'old world' technology (such as platforms, people and processes) versus what blockchain ledgers offer to enterprises and organisations in terms of improved efficiency, performance, security and access to business data. Blockchain is sometimes tainted by association to Bitcoin, Onecoin and others. But as cryptocurrencies and stock markets continue to rise and fall with volatility and the world economy emerges changed by coronavirus, working from home and the threat of inflation, many enterprises, organisations and governments are looking again at the powerful features of blockchain and wondering how DLT may help them adapt. This book is an ideal introduction to the practical and applied nature of blockchain and DLT solutions for business executives, business students, managers, C-suite senior leaders, software architects and policy makers and sets out, clearly and professionally, the benefits and challenges of the actual business applications of blockchain.

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.
An enterprise blockchain or distributed ledger technology (DLT) is very much like a shared document stored on a cloud drive. There are just two differences. First, there is no master copy of this document stored with an escrow or arbiter, and second, any change to the document happens only after it has been signed off by all required stakeholders. This allows businesses to form a peer-to-peer network and establish a common ground of truth without giving up its control in hands of a single organization. The decentralized nature of the ledger combined with version control or immutability of the stored data is perfect for fast account reconciliation, secure tracking and tracing of products, and transparent records with no costly third-party auditing. This book teaches you how to build such decentralized applications.What's Inside:* Covers v2.0 of Fabric. Examples written in TypeScript and JavaScript* Deploying to production across multiple nodes using Docker* Securing communications with TLS* Handling Data Privacy* Comprehensive coverage of Fabric CA Server and Client* Bonus chapters on Bitcoin and LDAPThe author has done justice to it by really starting from the basics and explaining with wit the core concepts and taking the reader slowly to the core of Fabric.- Satej Sahu, Senior Enterprise Architect, HoneywellA very beginner friendly introduction to a massive amount of data needed to operate in the blockchain world.- Gregory Reshetniak, Product Owner, Ocado TechnologyA detailed bible about Hyperledger Fabric. This book is mandatory in the blockchain world. - Krzysztof Kamyczek, Architect Software Developer, Luxoft
