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.

Running an end-to-end flow

This section is a quick recap of the learning in this chapter:

End-to-end flow

The following is a list of the steps executed so far while exploring the university use case and engaging with OBP to experiment with the development process on OBP:

  • Identified who is a founder of the blockchain network (in our case, it is OEU)
  • Found the participant organizations of the network (in our case, it is CVS and ORS)
  • Created a founder and two participant instances in OBP
  • Exported the Orderer certificate of the founder
  • Imported the Orderer certificate to the network tab of both participant organizations
  • Exported the network certificate of each participant organization
  • Added both the organizations' certificates to the founder network
  • Created a channel, channeleducation, in the founder for all three organizations: the founder and the two participants
  • Joined peers...
