# BigQuery

> Access Allium data in your own native GCP/BigQuery environment.

export const chainCount = '85+';

Allium offers access to blockchain data through BigQuery Data Shares via Google Cloud's native [Analytics Hub](https://cloud.google.com/analytics-hub).

## Getting Started

To set up your BigQuery data share, we only need your GCP IAM account email address. Once provided, we can share the complete blockchain history in seconds.

<Tip>
  **Account Options**

  You can use either:

  * Your personal email address
  * A [service account](https://cloud.google.com/iam/docs/service-account-overview) email address (recommended for production)
</Tip>

## Supported Blockchains and Schemas

Our BigQuery integration currently supports historical batch data with comprehensive blockchain coverage.
