Bigchaindb
BigchainDB is a blockchain data management system designed to store large datasets on a distributed ledger while maintaining the query performance of a traditional database. It provides immutable record storage for data and digital assets, ensuring a verifiable history of all entries.
The project integrates a decentralized blockchain structure with a NoSQL database backing to enable efficient indexing and complex data lookups. It uses a consensus-based state replication model and immutable transaction logging to prevent unauthorized record alteration.
The system exposes the ledger state and write operations through a JSON-RPC API and HTTP-based data streaming. These interfaces allow for programmatic interaction and the retrieval of records using filters and lookups.
Features
- Distributed Ledger Databases - Provides a distributed ledger database that integrates blockchain structure with NoSQL performance for verifiable data integrity.
- Blockchain Data Management - Provides a system for storing large datasets on a blockchain while retaining the query performance of a traditional database.
- Blockchain State Querying - Retrieves records using filters and lookups while preserving the immutable properties of the distributed ledger.
- Immutable Asset Commits - Maintains a decentralized ledger of assets using immutable commits to ensure records cannot be altered.
- NoSQL Databases - Uses a high-performance NoSQL database as the underlying storage layer to enable efficient indexing and complex lookups.
- Consensus-Based Replication - Implements a consensus-based replication model to synchronize data across multiple nodes and ensure a single immutable state.
- Blockchain Data Storage - Saves records on a distributed ledger to combine permanent data integrity with fast query performance.
- Ledger Querying - Provides interfaces for filtering and retrieving specific records from a blockchain ledger via web requests.
- Blockchain Transaction Logs - Appends every data change to a cryptographically linked chain of blocks to prevent unauthorized record alteration.
- Immutable Data Storage - Saves records to a decentralized ledger to ensure data integrity while maintaining fast database lookups.
- HTTP Ledger Streaming - Delivers large sets of ledger data to clients using standard HTTP web requests for seamless integration.
- Decentralized Asset Registries - Maintains a permanent, decentralized record of digital assets to prevent unauthorized alteration or deletion.
- HTTP Data Exposure APIs - Streams ledger data to external clients using standard web requests to facilitate programmatic interaction.
- JSON-RPC Interfaces - Exposes the ledger state and write operations through a standard JSON-RPC interface for programmatic access.
