#What Challenges Exist in Accessing Blockchain Data?
Accessing useful data from a blockchain can be a complex process. BloxBean has addressed this challenge for Cardano developers by introducing the Analytics Store, a groundbreaking module within its Yaci Store project. This innovation enables seamless export of Cardano’s entire on-chain history into open, portable Parquet files.
The Cardano Foundation supports this initiative by providing engineering resources to ensure the tool achieves a high level of readiness for production.
#How Does the Analytics Store Simplify Data Export?
The Analytics Store effectively bridges the data accessibility gap by continuously synchronizing data from PostgreSQL into well-organized Parquet files. Utilizing an internal DuckDB engine, it transforms the labor-intensive tasks of indexing and querying blockchain data into simple, lightweight exports that are ready for analysis. This means any data analysis tool can effortlessly integrate and work with the exported data.
Parquet is a columnar storage format commonly used in data engineering, natively compatible with popular tools such as Python's pandas and Apache Spark. By exporting Cardano data in this accessible format, BloxBean is enabling data analysts to work efficiently without the need to learn complex blockchain-specific tools.
The module supports features like automatic syncing and optional DuckLake catalog management, ensuring that the exported data remains current with minimal manual effort. It is available for deployment in various ways, including Docker, standalone JAR, and embedding into existing applications, with capabilities for both mainnet and testnets.
#How Has Yaci Store Grown from Community Project to Production Infrastructure?
Originally conceived as a community-driven initiative, Yaci Store has transformed into a modular, high-performance indexer for Cardano, developed with the Cardano Foundation's direct support. Version 2.0.0 was released on February 3, 2026, introducing native capabilities for deriving ledger and governance states. This update was crucial as it allowed the tool to derive essential blockchain states independently, without needing external components.
The launch of the Analytics Store module on June 14, 2026, built upon this strong foundation. The Cardano Foundation incorporates Yaci Store into its Rosetta Java implementation, further enhancing its functionality and reliability. This integration fuels consistent analytics, such as those seen with SundaeSwap Scooper Analytics, thereby supporting deeper insights into the Cardano ecosystem.
