Features

• Tamperproof Records - Maintains a tamperproof record of entries using cryptographic commit logging to ensure a verifiable history of all changes.
• Merkle-Tree Data Integrity - Employs Merkle trees to generate cryptographic membership and consistency proofs that verify data integrity.
• Append-Only Storage Engines - Uses an append-only storage engine to maintain a verifiable and permanent history of all data changes.
• Historical Data Querying Interfaces - Enables retrieval of previous data versions by querying specific transaction IDs or temporal ranges.
• Document Storage Managers - Provides storage and retrieval of document-based data featuring dynamic field management and collection-level auditing.
• Data Replication - Distributes data across a cluster of nodes in real-time to ensure high availability and consistent state.
• Relational - Implements a relational storage model allowing structured data retrieval using SQL, including complex joins and window functions.
• Database Replication - Ensures high availability and data redundancy through synchronous node replication across a distributed cluster.
• Cryptographic Commit Logs - Maintains an immutable record of data using a cryptographic commit log to ensure a verifiable history.
• Multi-Model Databases - Unifies key-value, document, and relational data structures within a single immutable storage engine.
• PostgreSQL-Compatible Databases - Implements the PostgreSQL wire protocol to allow integration with standard SQL clients, ORMs, and database tools.
• Key-Value - Manages a tamperproof store of key-value pairs with support for atomic batch operations and sorted sets.
• Storage Immutability - Maintains a tamperproof record of entries to ensure a verifiable history of all changes.
• Immutable Logs - Records every system operation in a tamperproof, append-only store to create a verifiable activity trail.
• Backup and Recovery - Enables the creation of offline database state backups and restoration for disaster recovery.
• Database State Differencing - Allows identifying inserted, updated, or deleted rows between two points in time using difference queries.
• PostgreSQL Protocol Compatibility - Implements a PostgreSQL-compatible wire protocol to allow connectivity with standard SQL clients and ORMs.
• Database Access Controls - Manages granular permissions and roles to restrict user access to specific databases or operations.
• Mutual TLS Authentication - Protects client-server communication using mutual TLS certificate exchange and token-based authentication.
• SQL Verification Interfaces - Allows querying the cryptographic proof system via SQL to validate that data has not been tampered with.
• Audit Logs - Provides a verifiable activity trail by recording every operation as a structured JSON event in a tamper-proof store.
• Cryptographic Audit Trails - Employs a dedicated agent and immutable audit trails to detect and notify of data tampering.
• Server Activity Logs - Records server operations as structured JSON events in a tamper-proof store for immutable history tracking.
• Database Engines - Lightweight, high-speed immutable database.
• Database Systems - Listed in the “Database Systems” section of the Awesome Go awesome list.
• Databases - Database with built-in cryptographic proof and verification.
