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.

That brings us to the end of this chapter. This chapter should help you design decentralized trading exchanges, or exchanges on a distributed blockchain network in general. It should also help you to port concepts of trading, such as orderbooks and matching engines, to blockchain very easily. The example case that we looked at uses only a single orderbook pair, gold versus US dollars, but it can be very easily expanded to support multiple orderbook pairs and assets, and can be scaled into a full-sized exchange with additional components and security checks in place. You can run this on a private blockchain for an enterprise, or deploy it on a public blockchain. Bear in mind that public blockchains will require gas for each transaction, and you might want to club transactions together. Also, your orderbook will be visible to everyone on the public blockchain.
