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.

Strong identities – the key to the security of the Hyperledger Fabric network


Strong identities are at the heart of Hyperledger Fabric security. Creating, managing, and revoking these identities is critical to the operational security of Hyperledger Fabric-based deployment. The identities are issued by a MSP. As shown in the previous Hyperledger Fabric architecture diagram, one logical MSP is typically associated with one peer. An MSP can issue any appropriate cryptographically signed identities. Hyperledger Fabric ships with a default MSP, (Fabric CA), which issues X.509 certificates to the authenticated entities.

Bootstrapping Fabric CA

Fabric CA can be configured with a LDAP server or run in a standalone mode. When running in a standalone mode, it must be configured with a bootstrap identity that gets stored in the backend database of Fabric CA. By default, a SQLite database is used but, for production usages, a PostgreSQL or a MySQL database can be configured. Typically, the connection...
