Overview of this book

Blockchain and Hyperledger are open source technologies that power the development of decentralized applications. This Learning Path is your helpful reference for exploring and building blockchain networks using Ethereum, Hyperledger Fabric, and Hyperledger Composer. Blockchain Development with Hyperledger will start off by giving you an overview of blockchain and demonstrating how you can set up an Ethereum development environment for developing, packaging, building, and testing campaign-decentralized applications. You'll then explore the de facto language Solidity, which you can use to develop decentralized applications in Ethereum. Following this, you'll be able to configure Hyperledger Fabric and use it to build private blockchain networks and applications that connect to them. Toward the later chapters, you'll learn how to design and launch a network, and even implement smart contracts in chain code. By the end of this Learning Path, you'll be able to build and deploy your own decentralized applications by addressing the key pain points encountered in the blockchain life cycle. This Learning Path includes content from the following Packt products: • Blockchain Quick Start Guide by Xun (Brian) Wu and Weimin Sun • Hands-On Blockchain with Hyperledger by Nitin Gaur et al.

How to choose a proper use case


With so much speculation about blockchain technology and its potential impacts on existing business models, it is a time to be realistic.  In Gartner's most recent Hype Cycle for Emerging Technologies report, blockchain is said to have entered the trough of disillusionment phase, the third phase of the company's hype cycle metric, as shown in the following screenshot:

 

Between Q4 2017 and Q1 2018, the price of 1 BTC reached above 19K and then quickly dropped down 10k in a matter of days. It is 3.4K on December 11, 2018. This eye-popping roller-coaster in BTC price has led to the cooling down of frantic speculations on cryptocurrencies and consequently a reduction in investment in cryptocurrency projects. In addition, the limitations of the technology are also a factor, making the technology unsuitable for certain use cases. A well known issue is the low rate of transactions per second (TPS) inherited by most blockchain platforms from Bitcoin, as discussed in...
