Dereward⭐ System

The Dereward⭐ system is designed to listen to events from the consumer contract on the Phala network, store them in a PostgreSQL database, and evaluate conditions to determine if a user can mint a reward collection.

System Diagram

System Overview

• User Query: A user queries the consumer with a request using an Ethereum address.
• Lens ID Retrieval: The system retrieves the lens ID associated with the Ethereum address by querying the GraphQL from lens.dev. (Note: There's a plan to implement this on the Phala network).
• Event Listening: A worker listens for the response event from the consumer contract.
• Data Storage: Once the event is captured, the worker stores the event data in a PostgreSQL database.
• Data Decoding: The system then decodes the values from the event log to retrieve ${totalPosts} and ${totalMirrors}.
• Condition Evaluation: These values are then queried against the stat field in one or more reward collections.
• Minting Decision: If the conditions match, the system determines which collections the user can mint. If not, the user cannot mint any collections.

Running the System

To run the system, execute the init.sh script:

./init.sh
