GlobalStorage

The Concept

📦 globalstorage is a modular distributed database for JavaScript and the Web—featuring blockchain integrity, local-first sync, CRDTs, and smart contracts.

Key Features

• Distributed architecture with global unique IDs and deterministic replication
• Blockchain log for tamper-proof operation history
• JavaScript Smart Contracts executed within your app
• CRDT synchronization for offline-first and P2P support
• Local-first storage: supports fs, IndexedDB, and OPFS
• Metaschema-driven domain modeling for validation and sync
• CAS operations for consistency and concurrency safety
• Web-ready: works in Web browsers and Node.js runtime
• Secure transport via metacom protocol and WebSocket
• Crypto support: RSA, SHA-256, and more
• Built-in integration with Impress Application Server

Ideal For

• Local-first apps
• Real-time collaboration tools
• P2P distributed systems
• Full-stack JavaScript projects
• Blockchain-based data pipelines

Additional features

• Built-in database engine will minimize interprocess communication to access data
• Minimize data transformations: all data slould be stored, stansmitted, handled and placed in RAM in the same format
• Maximum memory usage, read-ahead and lazy-write, minimizing data conversion
• Using metadata everywhere, special declarative format for subject domein representation (including fields, relations, and indices), memory structures, GUI, API, etc.
• The same API for client-side runtime and server-side runtime:
  • server-side storage engine
  • client-side storage engine (multiple implementations for different platforms including mobile, desktop and browser)
  • sharding for distributed storage of large data amounts, geo-distribution, save backup copies, access load balancing
  • allows user to exchange data in P2P mode
• Syncronization between client and server in realtime (close to realtime) and in lazy mode
• Offline-first approach: applications can work in online and offline (with locally stored data)
• Bidirectional data sync with CRDT and hieratchical versioning like git have
• Global data structures unification for applications working with Metarhia technological stack and Impress application server
• Ability to work with non-unified data structures (custom schemas), specific to certain subject domain
• Data structures have global distributed identification system, so data can be inserted anywhere and will not bring ID conflicts
• Data reliability is provided by distributed storage facilities, so each data structure should have master server and multiple backup and cache servers; using those servers globalstorage supports addressing, versioning and branching
