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.

Configuring your Git repository


In this section, we will see how to properly protect our Git repository by doing the following:

  • Setting the code owners of our smart contract
  • Protecting the master branch
  • Configuring Git for commit signing and validation
  • Testing the process by submitting a pull request

Setting the code owners of our smart contract

We will start by defining the code owners for our smart contract.

Ideally, in a large consortium, the code owners should not be the same group as the one that modifies the code. Remember, these steps are meant to reinforce the trust in the network.

Code owners are defined in a file called CODEOWNERS, which can reside either in the root directory or the .Github directory. GitHub allows us to define different code owners depending on file patterns, so while we could get very creative, we will focus on a few artifacts from our Hyperledger composer project:

  • package.json: As it controls the build and packaging process, this represents a key file to control.
  • header...
