# Data Quality Verification

## Data quality checks

We believe in full transparency to our users on the completeness and veracity of our data.

Allium runs regular data status checks ([https://status.allium.so/](https://status.allium.so/)) and ([https://app.allium.so/status/chains](https://app.allium.so/status/chains))

* **Existence Checks**: Ensuring that every block, trace, log, and transaction exists on the fundamental raw data level
* **Entity Consistency Checks**: Ensuring the blocks are in order, and the number of transactions matches
* \*\*Sub-entity Consistency Checks: \*\*Ensuring the internal fields are correct, as RPCs can flake, especially during version upgrades
