Hands-On Smart Contract Development with Hyperledger Fabric V2 (ebook) Kolonowskie

Blockchain technology continues to disrupt a wide variety of organizations, from small businesses to the Fortune 500. Today hundreds of blockchain networks are in production, including many built with Hyperledger Fabric. This practical guide shows developers how the latest version of this blockchain infrastructure provides an ideal foundation for developing enterprise blockchain applications or solutions.Authors Matt Zand, Xun Wu, and Mark Anthony Morris demonstrate how the versatile design of Hyperledger Fabric 2.0 satisfies a broad range of industry use cases. Developers with or without previous Hyperledger experience will discover why no other distributed ledger technology framework enjoys such wide adoption by cloud service providers such as Amazon, Alibaba, IBM, Google, and Oracle.Walk through the architecture and components of Hyperledger Fabric 2.0Migrate your current Hyperledger Fabric projects to version 2.0Develop blockchain applications on the Hyperledger platform with Node.jsDeploy and integrate Hyperledger on Amazon Managed Blockchain, IBM Cloud, and Oracle CloudDevelop blockchain applications with Hyperledger Aries, Avalon, Besu, and GridBuild end-to-end blockchain supply chain applications with Hyperledger Spis treści: Preface How to Build Enterprise Blockchain Applications with Hyperledger Who Is This Book For?
