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.

Issuance claim


In this section, we will explore and implement an issuance claim use case. 

No one wants to have an insurance claim, but when things do go wrong and accidents happen, this may result in financial losses. These losses will be covered by your insurance policy. The traditional insurance claims process has stayed the same for decades, as there are a number of key issues in the process, including false claims, fraud detection, slow and complex claims processing, human error, undesirable customer experience, and inefficient information flows in reinsurance.

With blockchain, the transaction record in the ledger is immutable and the state data can only be updated when all parties agree. The record in the blockchain can be shared in real time. This allows insurers to move quickly, as most of the required information for claims verification can be processed in no time. Insurers can track the use of asset data in the blockchain. The paperwork can be eliminated and customers can submit...
