The primary purpose of writing contract source code on a local PC is to facilitate the creation of instances of the contract on a network. This process is essential in the development and deployment of smart contracts, as it allows developers to code their logic using programming languages designed for blockchain environments, such as Solidity for Ethereum.

When the source code is written locally, developers can test and debug their smart contracts in a controlled environment before deploying them to a live blockchain network. Once the code is finalized and confirmed to work correctly, it can then be compiled and deployed, resulting in the creation of contract instances on the blockchain. Each instance performs the functions defined in the source code and interacts with other transactions and contracts according to the rules embedded in the code. Thus, the work done on a local PC is a fundamental step in preparing the smart contract for deployment and interaction within a decentralized environment.
