# Required Tools

## dbSync

Installation instructions can be found [here](https://github.com/input-output-hk/cardano-db-sync/blob/master/doc/docker.md).

Ensure dbSync and the PostgreSQL database are running, and the database is synchronized past 22:00 UTC on January 9th, 2026.

*Note: IF your dbSync is not synchronized to at least this date, the results from running a snapshot will be inaccurate. This is because the snapshot is taken at a time when a rollback on the blockchain is impossible to affect the snapshot data, and therefore it's fully reproducible and stable. This is guaranteed by placing one full Epoch between the registration deadline and the earliest the final snapshot can be taken.*
