Foreword

In my role as the chair of the Hyperledger Technical Steering Committee, I've

come to realize the great divide between the enormous hype surrounding

blockchain and the depth of understanding of how blockchain technology works,

where the technology is on the maturity curve, and how it might be leveraged in

the context of the enterprise.

Most of the hype relates to the cryptocurrency aspects of public, permission-less

blockchain—ICOs as a substitute for more traditional IPOs, and the potential for

disrupting traditional systems of banking, insurance, securities, and so on. It is

the potential for disruption and the asymmetric profits that disruption might

yield that have driven many to explore how blockchain might be used to one

company's advantage over the rest of a given domain. However, what many are

discovering is that blockchain is a team sport, and for blockchain to be

successful in an enterprise, it demands a degree of industry collaboration not

seen before.

The authors of this book take you beyond the hype. They lay a solid foundation

for understanding the state of the technology landscape—including active and

incubating projects under development at Hyperledger. They provide you with a

framework for choosing the right technology platform, designing your solution,

and integration with existing systems. And they explain the various governance

models for establishing and operating a blockchain business network.

If you are an enterprise architect or developer tasked with developing a

blockchain solution for your enterprise or industry, this book is a must-read.

Cheers,
