Blockchain for Enterprise

By: Narayan Prusty

Overview of this book

The increasing growth in blockchain use is enormous, and it is changing the way business is done. Many leading organizations are already exploring the potential of blockchain. With this book, you will learn to build end-to-end enterprise-level decentralized applications and scale them across your organization to meet your company's needs. This book will help you understand what DApps are and how the blockchain ecosystem works, via real-world examples. This extensive end-to-end book covers every blockchain aspect for business and for developers. You will master process flows and incorporate them into your own enterprise. You will learn how to use J.P. Morgan’s Quorum to build blockchain-based applications. You will also learn how to write applications that can help communicate enterprise blockchain solutions. You will learn how to write smart contracts that run without censorship and third-party interference. Once you've grasped what a blockchain is and have learned about Quorum, you will jump into building real-world practical blockchain applications for sectors such as payment and money transfer, healthcare, cloud computing, supply chain management, and much more.

Understanding blockchain interoperability


Interoperable blockchains are blockchains that can talk to each other. Each blockchain can read the other's state. There will be many occasions when you will want to enable your smart contracts to talk to centralized or other decentralized apps. When we talk about interoperability between DApps we're talking about something different than interoperability between blockchains.

Note

Enabling an Ethereum smart contract to check whether a file exists in IPFS or not is enabling interoperability between DApps, whereas enabling an Ethereum smart contract to fetch a Bitcoin account balance is enabling interoperability between blockchains.

Getting Ethereum smart contracts to make REST APIs call to centralized apps is considered enabling interoperability between Ethereum and WWW. But in this chapter, we will learn about interoperability between blockchains, specifically interoperability between Quorum networks.
