Hyperledger and Enterprise Blockchains

Unlike most of the other blockchain systems discussed in this book, Hyperledger never had an Initial Coin Offer (ICO) and has no tokens that are publicly traded. This is because Hyperledger isn't a blockchain itself, but instead a collection of technologies used for the creation of new blockchains. Moreover, these blockchain technologies were explicitly designed and built for enterprise use cases and not the public markets.

In this chapter, we will cover the following items:

The history of Hyperledger
Critical details about each of the six current Hyperledger projects
An overview of the Hyperledger tools used to support the ecosystem
Suggestions on how to select Hyperledger technologies for a project

The Hyperledger name doesn't apply to a single technology, but rather a collection of blockchain technologies all donated to the...

History of Hyperledger

The Hyperledger project was founded in 2015, when the Linux Foundation announced the creation of the Hyperledger project. It was founded in conjunction with a number of enterprise players, including IBM, Intel, Fujitsu, and JP Morgan. The goal was to improve and create industry collaboration around blockchain technology so that it would be usable for complex enterprise use cases in the key industries most suitable to blockchain disruption: technology, finance, and supply chain.

The project gained substance in 2016, when the first technology donations were made. IBM donated what was to become known as Hyperledger Fabric, and Intel donated the code base that became Hyperledger Sawtooth.

Unlike most projects in the blockchain space, Hyperledger has never issued its own cryptocurrency. In fact, the executive director of Hyperledger has publicly stated that there...

Hyperledger projects

As mentioned, a hyperledger isn't a single blockchain technology, but rather a collection of technologies donated by member companies. While there is a long-term goal of greater integration between projects, currently most of the Hyperledger projects function independently. Each project's core code base was donated by one or more of the Hyperledger member organizations, based on problems they were trying to solve internally before open sourcing the code and handing ownership to the Linux Foundation.

Hyperledger Burrow

Hyperledger Burrow is a re-implementation of the Ethereum Virtual Machine (EVM) and blockchain technology, but with a few key changes. First, instead of using the proof-of-work...

Tools in Hyperledger

An often overlooked aspect of any application is the need for helpful tools to manage the life cycle of that application. Tools, such as software to ease deployment, debugging, and design, can make a tremendous difference in the ease of use of a system, for developers and users alike. Most public blockchains are severely hampered by the lack of high-quality tools and support. The Hyperledger ecosystem, however, continues to invest in building excellent support tools.

Hyperledger Caliper

One of the common needs for any system is benchmarking. Hyperledger Caliper is a blockchain-oriented benchmarking tool, designed to help blockchain architects ensure that the system can perform fast enough to meet the needs...

Summary

Now you have a good idea of the different subprojects that make up Hyperledger and an awareness of the tooling you can use to build Hyperledger-based projects. Hyperledger is a set of technologies for building private blockchain networks for enterprises, versus the public and tradeable networks, such as Ethereum and Bitcoin. The Hyperledger family is made of six projects and a set of support tools, all with subtly different focuses and advantages to suit different projects.

Over time, the different projects are expected to become more consistent and interoperable. For instance, Hyperledger Burrow and Hyperledger Sawtooth have already cross-pollinated with the Seth transaction family, which allows Sawtooth to run Ethereum smart contracts. It is expected that tools such as Cello and Composer will be extended to support additional Hyperledger projects in time, leading to...
