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.

Engaging with a use case

In the Design strategy section, we tried to define a blockchain design strategy that consists of five steps: explore, engage, experiment, experience, and influence. In this section, we will concentrate on the second step. During this step, we will engage with one of the use cases we defined in previous section. Chapter 5, Managing Solution on Oracle Blockchain Platform, and Chapter 6, Developing Solutions on Oracle Blockchain Platform, take care of experimenting with the solution. There, we will define another use case and try to build the chaincode for the solution. We will also set up and configure a blockchain network to run the chaincode and use integration via REST to connect with the chaincode.

In this chapter, while engaging with the use case, we will start by defining the flow—first the as-is flow and then the to-be flow. We have covered...
