## What it is
Chainquery is a Go daemon and API server that parses the LBRY blockchain into a structured MySQL database, syncing blocks, transactions, addresses, and the LBRY claim system. It exposes an HTTP API including a read-only SQL endpoint so chain data can be queried with plain SQL instead of RPC calls.

## Use cases
- query lbry blockchain data with sql
- index blockchain blocks into a database
- build an explorer for lbry claims and channels
- sync blockchain data in real time
- serve blockchain data over an http api
- analyze lbry transactions and supports

## When to choose
- you need fast structured queries over LBRY chain data
- you want to avoid walking the chain via JSON-RPC
- you need automatic handling of blockchain reorganizations
- you're building apps or analytics on the LBRY ecosystem

## When to avoid
- you work with a different blockchain than LBRY
- you only need occasional raw RPC calls rather than indexed data
- you don't want to operate a MySQL database and full node
