Cosmos event attributes are key-value pairs that provide more detailed information about a categorized event. These attributes help filter and identify specific aspects of an event. Based on the provided example, the Cosmos event attributes include the following key-value pairs:
  1. msg_index: Identifies which messages relate to the same transaction. This is reflected in the transaction_index field.
  2. event_type: Categorizes the event at a high-level, such as “message”. This helps filter events by message type within the Cosmos SDK.
  3. key: A specific attribute key related to the event, for example, “module”.
  4. value: The value associated with the attribute key, for example, “staking”.
