HAlive

HAF-based Alive Protocol streams indexer and API server. Indexes Hive from a starting block number for Alive-related custom_json operations using the HAF app sync algorithm.

Required Dependencies

• nodejs and npm (Latest LTS, v18 minimum supported)
• Synced HAF node
• AliveDB node

A locally-running IPFS daemon is recommended for faster chunk fetching.
