Blockchain Development for Finance Projects

By: Ishan Roy

Overview of this book

Blockchain technology will continue to play an integral role in the banking and finance sector in the coming years. It will enable enterprises to build transparent and secure business processes. Experts estimate annual savings of up to 20 billion dollars from this technology. This book will help you build financial apps using blockchain, guiding you through enhancing popular products and services in the banking and finance sector. The book starts by explaining the essential concepts of blockchain, and the impact of blockchain technology on the BFSI sector. Next, you'll delve into re-designing existing banking processes and building new financial apps using blockchain. To accomplish this, you'll work through eight blockchain projects. By demonstrating the entire process, the book helps you understand everything from setting up the environment and building frontend portals to system integration and testing apps. You will gain hands-on experience with the Ethereum, Hyperledger Fabric, and Stellar to develop private and public decentralized apps. Finally, you'll learn how to use ancillary platforms and frameworks such as IPFS, Truffle OpenZeppelin, and MetaMask. By the end of this blockchain book, you'll have an in-depth understanding of how to leverage distributed ledgers and smart contracts for financial use cases.

Building the private test Stellar network

For building our project, we'll launch a simple Stellar network that contains a single blockchain node and a single client/server. The blockchain node in Stellar is called Stellar Core, while the client-server is called Horizon. Horizon is a client API server that extends a suite of handful endpoints, allowing application developers to view transaction data and statistics, and to submit transactions to the core blockchain node. Similar to web3-js, Stellar has a JavaScript SDK that allows us to build requests in order to interact with Horizon.

Stellar provides a handy Docker image that can be used to quickly launch an ephemeral (temporary) or persistent (permanent) container for implementing the Stellar network. This Docker container contains an instance of Stellar Core, an instance of Horizon, installed dependencies such as PostgreSQL...
