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.

Designing the solution

Now that we have qualified our use case for a blockchain-based solution, let's get down to designing the solution in line with the constructs of OBP.

There is no fixed sequence of steps for the design process. It is up to the solution designer's discretion. The primary objective should be to achieve clarity on various aspects of an OBP solution, from a logical view to deployment aspects.

Business network topology

As we mentioned previously, for our use case, we are considering three stakeholders. These are OEU, ORS, and certificate viewers/verifiers (let's give this an acronym of CVs). We need to determine the roles of each of these stakeholders based on their function:

  • OEU is the university...
