cryo is the easiest way to extract blockchain data to parquet, csv, or json

cryo is also extremely flexible, with many different options to control how data is extracted + filtered + formatted

cryo is an early WIP, please report bugs + feedback to the issue tracker

note that cryo's default settings will slam a node too hard for use with 3rd party RPC providers. Instead, --requests-per-second and --max-concurrent-requests should be used to impose ratelimits. Such settings will be handled automatically in a future release.
