CommentRewarder is a service on Hive that rewards comments to boost engagement. It selects comments based on quality, relevance, and recency to the parent post, scanning recent activity across the blockchain.
Incentivization works via automated upvotes from a dedicated account (like @commentrewarder), distributing Hive rewards (HP/HP) to qualifying comments. Users can opt-in by following the service or tagging posts; rewards scale with comment value and Hive consensus.
