Oracle Blockchain Quick Start Guide

By: Vivek Acharya, Anand Eswararao Yerrapati, Nimesh Prakash

Overview of this book

Hyperledger Fabric empowers enterprises to scale out in an unprecedented way, allowing organizations to build and manage blockchain business networks. This quick start guide systematically takes you through distributed ledger technology, blockchain, and Hyperledger Fabric while also helping you understand the significance of Blockchain-as-a-Service (BaaS). The book starts by explaining the blockchain and Hyperledger Fabric architectures. You'll then get to grips with the comprehensive five-step design strategy - explore, engage, experiment, experience, and in?uence. Next, you'll cover permissioned distributed autonomous organizations (pDAOs), along with the equation to quantify a blockchain solution for a given use case. As you progress, you'll learn how to model your blockchain business network by defining its assets, participants, transactions, and permissions with the help of examples. In the concluding chapters, you'll build on your knowledge as you explore Oracle Blockchain Platform (OBP) in depth and learn how to translate network topology on OBP. By the end of this book, you will be well-versed with OBP and have developed the skills required for infrastructure setup, access control, adding chaincode to a business network, and exposing chaincode to a DApp using REST configuration.

HLF – features and qualifiers

Along with the Linux Foundation, various companies, such as Fujitsu, and IBM, are collaborating on the HLF project. HLF is a permissioned blockchain framework that is designed and architected to develop modular applications.

The following are the key features of the Hyperledger framework:

  • HLF is governed by excellent, diverse technical steering committees from various organizations.
  • HLF is modular and configurable, which makes it useful for various use cases, ranging from banking, finance, and the supply chain, to education and healthcare.
  • It is a DLT where chaincode is authored in general-purpose programming languages, such as Java, Go, and Node.js, instead of programming in DSL (domain-specific languages). This also brings HLF closer to enterprises that have applications and resources built and skilled in these languages.
  • HLF is a DLT that...
