Core Functions
The contract includes essential operations for dataset management:

mintDataset
Registers a dataset, requiring the registration fee and storing the Dataset struct.
getDataset
Retrieves dataset details by ID, ensuring transparency for consumers.
revokeDataset
Deactivates a dataset, restricted to its provider, clearing the CID and setting isActive to false.
The smart contract implementation incorporates several security patterns to protect both providers and consumers:
Access control modifiers restrict sensitive operations to authorized parties
Event emissions create an immutable audit trail of all significant actions through the event system
Input validation prevents malformed data or invalid parameters
Weight optimization techniques reduce transaction costs for high-volume operations
