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.

Network bootstrap and governance – the first step towards security


When organizations decide to form a permissioned private blockchain network using Hyperledger Fabric, they need to consider several governance aspects, which will ultimately determine the overall security posture of the network. These governance aspects include, but are not limited to the following:

  • How shall the network be bootstrapped and the members verified to create the network? Network bootstrap is the first step in creating a blockchain network. Different entities may come together to create a network. The entities may have an out-of-band communication to agree upon with the first set of members and establish governance policies, which will be discussed next.
  • What is the process for a new entity to join the network (or a channel)? Defining a policy for admitting new members in the network is paramount and is governed by the business needs of the network.
  • Who can deploy and upgrade chaincodes on peers in the network? Defining...
