GPU.sol
This Solidity contract is like the rulebook for a system that manages GPUs (Graphics Processing Units) and the tasks they perform on a GAN Chain network. Here's what it does:
Ownership and Upgradability: The contract makes sure that only the owner can make certain changes to it, like updating its functions. This ensures the contract's security and allows for upgrades if needed.
Keeping Track of Important Things: It keeps track of different things using unique numbers called IDs. These include IDs for machines, jobs, users (like providers, consumers, and queens), and types of GPUs.
Describing Different Parts: There are different types of entities in this system, like providers (who own machines), consumers (who use the machines for tasks), and queens (who oversee tasks). Each has its own set of information stored.
Storing Data Efficiently: Think of mappings like well-organised filing cabinets. They store and organise data based on different categories, making it easy to find and use later.
Setting Rules Before Doing Things: Modifiers act like security guards. They check if certain conditions are met before allowing actions to happen. For example, making sure a user has a special token (NFT) before they can do something.
Keeping a Log of Important Events: Events are like notes in a diary. They record when important things happen in the system, like when a job is created or completed. This helps keep track of what's going on.
Doing Different Jobs: The contract has many functions, each like a task it can perform. These tasks include adding new types of GPUs, updating GPU prices, adding users to the system, creating jobs for the machines, and checking if the machines are healthy.
Getting Information: Finally, there are functions that help you get information from the system, like getting a list of providers or finding out details about a specific provider's machines.
Overall, this contract manages a system where providers offer GPU machines, consumers use them for tasks, and queens make sure everything runs smoothly. It follows certain rules to keep everything fair and secure.
