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.

Strategies for implementing blockchain interoperability

Let's look at the various strategies with which you can achieve one or more of the previous use cases. We will learn the strategies that we can implement in Quorum, but not all the ones that are available for public or other blockchains. We will also look at examples of how to implement these strategies.

Single custodian

The easiest way to achieve interoperability is to have a centralized third-party through which blockchains can talk to each other. Essentially, you need to trust the third-party. 

However, centralized interoperability projects, such as Oraclize, have solved the trust problem. Oraclize enables your Ethereum smart contracts to communicate with the WWW; that is, it enables you to make REST API calls, fetch a Bitcoin account balance, check the file status in IPFS, and so on. Oraclize also provides a proof for smart contracts stating that the results have not been manipulated; therefore, Oraclize has tackled the trust issue...
