Blockchain across Oracle gives you the professional orientation to Blockchain that you need as an Oracle developer in today's changing world. Written and prepared for you by Oracle Developer Champion Robert van Molken, this book gets you up to speed with the details of the Blockchain - core concepts, how to implement Oracle's Blockchain Cloud Service, industry implications for the Blockchain, and how the Blockchain will affect your Oracle customers.
Robert van Molken introduces you to the history and concepts of the Blockchain. You'll really get to understand the Blockchain inside and out, as an Oracle developer or solution architect. You'll understand the Blockchain flow, and how the hashes and chains create a new decentralised paradigm for you as an Oracle developer. You'll gain insights into how the Blockchain affects Oracle developers and customers in this modern and disruptive era. You'll see how the Blockchain concepts work in this new world where Assets, Transactions, Security, and Privacy, can all be sustained across a decentralized system for your customers.
Then you'll find a detailed look at the cutting-edge Oracle middleware solutions. You'll learn about Hyperledger Fabric, the opensource Blockchain framework used by Oracle as its core, and how to set up your own Oracle Blockchain Network. You'll design and develop a smart contract, and learn how to run it on the Oracle Blockchain Cloud Service.
The final part of the book looks at how the Blockchain will affect your customers across various industry sectors. By studying industry trends in the financial services sector, healthcare industry, and the transport industry, you'll discover how the options and possibilities for you and your clients are being transformed by the Blockchain across Oracle. You'll complete this professional orientation by looking at Blockchain trends and future directions.
