This chapter highlighted the challenges and opportunities of DLT and blockchain. This chapter also drilled into various properties of blockchain and how those properties are upheaving the usage of blockchain in various scenarios. In this chapter, we also delved into modeling a use case and demonstrated the integration aspects and infrastructure for implementing a use case. The Design strategy section mentioned the five stages of this—explore, engage, experiment, experience, and influence. We also covered the initial two stages (explore and engage) of the design strategy. We explored the design strategy by examining various use cases, justifying the adoption of blockchain, and also tried to formulate an equation to justify/quantify the employment of blockchain for a given use case. Later, we engaged in the design strategy by defining a blockchain-based business network for a given use case. Here, we sketched flows and identified various blockchain-based business network components, such as assets, transactions, participants, events, access control, and channels. My next book, Blockchain for Solution Designers, covers design strategy extensively. In this edition, Chapter 5, Managing Solution on Oracle Blockchain Platform and Chapter 6, Developing Solution on Oracle Blockchain Platform, covers the experimental part of the design strategy, where you will learn to build a chaincode and run it on a blockchain platform. This allows you to experiment with the blockchain platform. From the next chapter onward, we will be exploring Hyperledger, its architecture, and other details.
