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.

Types of use cases

Broadly speaking, blockchain is an ideal use case for the decentralized consensus on ledgers that are appended by themselves on agreed transactions that are non-commutative. In this section, I'm going to categorize blockchain use cases into a few categories; however, I believe that there are millions of use cases, which is the result of non-commutative state transition functions. The listed categorization of use cases is exhaustive.

Let's start by simply putting the definition of blockchain into an equation:

Blockchain = Who Owns - What, When, and How much

When is the timeline, while How much is the quantity. However, What, is the topic of discussion here. My efforts to categorize blockchain are centered on What and Who.

WHAT: What represents the assets; essentially, the scarce assets that are valuable. Assets such as identity, currency, land title...
