Placeholder-avs-contract

Smart contracts to implement AVS (Actively Validated Service) that verifies sentiment analysis of user feedback.

Contract Events

NewTaskCreated

event NewTaskCreated(uint32 indexed taskIndex, Task task);

Tracks when a user submits new feedback to the system. Every feedback submission gets a unique ID (taskIndex) and includes:

  • The user's written comment
  • A rating (1-5)
  • The block number when submitted

Example:

{
    "taskIndex": 1,
    "task": {
        "comment": "Great service!",
        "rating": 5,
        "taskCreatedBlock": 21808375
    }
}

TaskResponded

event TaskResponded(
    uint32 indexed taskIndex,
    Task task,
    string sentiment,
    address operator
);

Tracks when an operator analyzes a piece of feedback. Records:

  • Which feedback they analyzed (taskIndex)
  • The original feedback details
  • Their sentiment analysis result (positive/negative/neutral)
  • The operator's address

Example:

{
    "taskIndex": 1,
    "task": {
        "comment": "Great service!",
        "rating": 5,
        "taskCreatedBlock": 21808375
    },
    "sentiment": "POSITIVE",
    "operator": "0x70997970C51812dc3A010C7d01b50e0d17dc79C8"
}
