TrueBlocks improves fully-local access to on-chain data for any blockchain. It consists of three main parts (1) an excellent indexer that indexes every appearance of any address anywhere on the chain, (2) a local binary cache that caches on-chain query results locally improving speed of analysis by 50-60 times over accessing node RPC endpoints (especially relevant for remote nodes), and (3) a large collection of tools making querying RPC data more convenient.
