# Overview of SonarX Full Historical Stream
> Comprehensive Blockchain Data from Genesis to Near Real-Time
SonarX Complete Historical Streaming offers comprehensive blockchain records, spanning from genesis to near real-time, that are fully indexed and easily accessible via SQL. Designed for institutions, enterprises, and other sophisticated data consumers, our historical datasets encompass over 120 chains and feature rigorous data quality controls to ensure completeness, consistency, and accuracy. These datasets are available via Snowflake, BigQuery, Databricks, and File drops in multiple formats (CSV, Parquet, Iceberg, etc.) and into all clouds (S3, GCS, ABS, etc.).
## Industry-Leading Chain Coverage
We have indexed and organized all of the data for every chain, so you don't have to. Schemas are normalized to provide an efficient querying experience across chains and tables. Tables include blocks, logs, decoded logs, traces, state diffs, priced transfers, and other related data. Furthermore, our tables are partitioned for optimal scanning and querying across these large datasets.
## **Technical Specs**
Highest quality (P90) re-org aware Historical Data
Minutes from tip (depending on each specific chain, this is the minimum amount of time necessary to achieve P90 re-org aware quality for the chain).
Available via APIs (batch delivery only), Snowflake, Databricks, BigQuery, Parquet / CSV/ Iceberg files, and replication on AWS, GCP, or Azure.
Complete historical streaming data across 120+ chains and all protocols, and counting.
From the genesis block to the latest finalized block across all 120+ chains that we cover.

## Access to sample data, Data Catalog, Schemas, and Data Dictionaries
Because our curation and enhancement processes are proprietary, we don’t share public samples or our complete Data Catalog. However, if you’d like to explore our datasets in more detail, you can easily sign up for access to SonarX's Console through [this form](https://console.sonarx.com) — no obligations, no sales pressure.
