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.
