Blockchain for Decision Makers

By: Romain Tormen

Overview of this book

In addition to cryptocurrencies, blockchain-based apps are being developed in different industries such as banking, supply chain, and healthcare to achieve digital transformation and enhance user experience. Blockchain is not only about Bitcoin or cryptocurrencies, but also about different technologies such as peer-to-peer networks, consensus mechanisms, and cryptography. These technologies together help sustain trustless environments in which digital value can be transferred between individuals without intermediaries. This book will help you understand the basics of blockchain such as consensus protocols, decentralized applications, and tokenization. You'll focus on how blockchain is used today in different industries and the technological challenges faced while implementing a blockchain strategy. The book also enables you, as a decision maker, to understand blockchain from a technical perspective and evaluate its applicability in your business. Finally, you'll get to grips with blockchain frameworks such as Hyperledger and Quorum and their usability. By the end of this book, you'll have learned about the current use cases of blockchain and be able to implement a blockchain strategy on your own.

When IBM joined the Hyperledger movement as a founding corporate member in 2016, it was already working on a blockchain framework that was integrated into the Hyperledger project and became the Fabric module. Original motivations for this initiative came from two observations made by the IBM team:

  • Bitcoin and Ethereum are barely scalable due to several drawbacks (an energy-consuming consensus protocol, a growing permissionless network, and an increasing database size).
  • Bitcoin and Ethereum do not support private transactions in their core model.

Since IBM spearheads most developments of Hyperledger Fabric by having contributed much of the code, it was expected that their solution called IBM Blockchain unveiled in March 2017 would make use of this specific module. This cloud-based solution enables developers to build robust and effective networks with improved security features...
