Book excerpt: This book is for anyone who is interested in learning or understanding blockchain technology through step-by-step programming. The ideal readers would be those with basic Java programming knowledge (either beginners or intermediate) as this book shows how to develop a preliminary blockchain system in Java. You may have wondered what blockchain is and how it works, and you may have heard of mining and wallet. There are quite a few books available out there talking about them. When you read those books, you may develop pieces of understanding here and there. Well, we know that learning by doing is the best education approach, which is what this book offers. In this book, each chapter begins with an explanation of blockchain concepts before moving on to discuss relevant Java programs that implement those concepts. You will accumulate knowledge via hands-on experience in code-writing and learn several versions of blockchain systems. The book includes all required source codes, which are also available online. After reading and practicing along with the book, you are ready to go as a blockchain developer.One advantage of this book is that no third-party software packages are required to follow along with the tutorials - everything explained in this book can be accomplished with OpenJDK, and the sample codes are written entirely in Java. The book is divided into multiple chapters with succeeding chapters building upon the concepts reviewed in previous chapters. However, each chapter covers inherently different material and so they can also be taken independently. The last chapter discusses the importance of secure coding and concludes the book with case studies of several malicious attacks that had occurred in the cryptocurrency world.

Download or read book Programming Hyperledger Fabric written by Siddharth Jain and published by Siddharth Jain. This book was released on 2020-12-10 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

With this focused guide, Bilgin Ibryam and Roland Huß from Red Hat provide common reusable elements, patterns, principles, and practices for designing and implementing cloud-native applications on Kubernetes. Each pattern includes a description of the problem and a proposed solution with Kubernetes specifics. Many patterns are also backed by concrete code examples. This book is ideal for developers already familiar with basic Kubernetes concepts who want to learn common cloud native patterns. You’ll learn about the following pattern categories: Foundational patterns cover the core principles and practices for building container-based cloud-native applications. Behavioral patterns explore finer-grained concepts for managing various types of container and platform interactions. Structural patterns help you organize containers within a pod, the atom of the Kubernetes platform. Configuration patterns provide insight into how application configurations can be handled in Kubernetes. Advanced patterns covers more advanced topics such as extending the platform with operators.
