Sprune

The goal of this project is to prune a Tendermint/CometBFT database of blocks and a Cosmos SDK application database, retaining only the last X versions. This prevents the need for state sync every few days.

This tool works with a subset of modules. While an application may have modules outside the scope of this tool, Sprune will prune the default SDK module and custom application module.

This tool is a refactored and modified version of the original Cosmprund.

How to Use

Sprune works on a data directory with the same structure as a normal Cosmos SDK/Tendermint node. By default, it will prune all but 100 blocks from Tendermint and all but 10 versions of application state.

Note: Application pruning can take a very long time depending on the size of the database.
