In the previous chapter, we learned how Quorum works and how the various consensus protocols safeguard it. Let's move on to writing smart contracts, now that we understand how Quorum works. Quorum smart contracts can be written using many languages; the most popular one is Solidity. In this chapter, we will learn Solidity, and build a DApp that enterprises can use to sign documents digitally.
In this chapter, we'll cover the following topics:
- The layout of Solidity source files
- Understanding Solidity data types
- Special variables and contract functions
- Control structures
- Structure and features of contracts
- Compiling and deploying contracts
