P2P Platform

Enterprise semantic graph database with blockchain-secured immutable ledger, W3C standards compliance (JSON-LD, RDF, SPARQL), and decentralized data composition capabilities . Note: Primarily a client-server database product with decentralized features, not a traditional P2P architecture. Classified as P2P Platform for tracking purposes within the CTA/OpenHaven context, but architecturally functions as an enterprise graph database akin to Neo4j or ArangoDB .

P2P Platform Attributes

Origins Founded by Brian Platz and Flip Filipowski as a Public Benefit Corporation to pioneer data-first technology with blockchain-secured semantic graph databases
Database Native RDF triple store with blockchain-secured immutable ledger; AVL-tree indexes; optional Lucene full-text index
Query Language FlureeQL (native JSON), SPARQL, GraphQL, SQL (limited)
Data Formats JSON-LD, RDF (Subject-Predicate-Object triples), Turtle
Collaborative Live Editing No
Rich Text Editing No
Mobile Support No (server-side database)
Web Support Yes (REST API, JavaScript SDK, React libraries)
Native Apps No
Terms AGPL (open source core); Commercial/Enterprise license available
Funds $28.1M total raised (8 rounds, 14 investors; latest $3.77M Series A-III, Feb 2025)
Based On RDF/W3C Semantic Web standards; blockchain/ledger technology for immutability
P2P Architecture Multi-node consensus (optional RAFT or PBFT); not P2P in traditional sense — nodes are server instances operated by administrators; decentralized federated query across distributed databases
Development Tools JavaScript/Node.js/React SDKs and libraries; Fluree CLI; REST API; Docker images; SPARQL and GraphQL endpoints auto-generated from schema
Deployment Options Single-node local (laptop), multi-node on-premise, cloud-native (any cloud), Docker/container, Fluree Cloud (hosted SaaS)
Authentication & Identity Data-centric security via SmartFunctions; SHA-256 asymmetric cryptography for ledger integrity; W3C Verifiable Credentials and DID registry support; zero-trust architecture
Storage Model Disk-oriented storage at ledger tier; in-memory indexes replicable to client via service worker for edge query; immutable append-only ledger with temporal metadata (time-travel queries)
Interoperability Native W3C compliance: JSON-LD, RDF, SPARQL, OWL/RDFS; federated query across disparate interoperable sources; data is FAIR (Findable, Accessible, Interoperable, Reusable); GraphQL API auto-exposed
Social Graph No native social graph (enterprise database; can model social relationships via RDF graph but no built-in social features)
