Cardano DB Sync

Cardano DB Sync follows the Cardano blockchain and stores chain data in a PostgreSQL database, making it easy to query historical blocks, transactions, staking, and governance data.

Architecture

The project has three main components:

• cardano-db — data types and PostgreSQL schema definitions
• cardano-db-tool — database management utilities (migrations, validation, rollbacks)
• cardano-db-sync — the main node that connects to a running cardano-node and syncs chain data to PostgreSQL

System Requirements (mainnet)

Quick Start

Choose your installation path:

• Installing from Source — build from source on Linux
• Installing with Nix — recommended for reproducible builds
• Docker — fastest way to get running locally
