Seed Hypermedia

Decentralized Data Protocol

A protocol and application suite for creating interconnected, collaboratively-edited hypermedia documents on a P2P network, built on a foundation of cryptographic identities, content-addressed data, and CRDTs for conflict-free collaboration

Decentralized Data Protocol Attributes

Origins Knowledge Base / Productivity
Database DAG (content-addressed Merkle-DAG of document changes using HLCs)
Query Language GraphQL (used in the daemon API for querying documents and entities)
Data Formats Custom Hypermedia format + JSON + Markdown export
Collaborative Live Editing Collaborative real-time editing (CRDT-based block-level editing with HLC-ordered merges)
Rich Text Editing Rich Text editing (block-based editor with headings, lists, embeds, transclusions)
Mobile Support Partial Mobile support (Android app available)
Web Support Yes (sites can be published to web gateways; web-based viewing)
Native Apps Native apps (desktop apps for macOS, Windows, Linux via Go daemon + Electron-like frontend)
Terms Self-hosting
Funds Undisclosed (seed-stage venture funding)
Based On IPFS (libp2p for networking), custom hypermedia protocol layer
P2P Architecture DHT + Mesh (libp2p-based peer discovery with gossip sync of document DAGs)
Overlay Network App-wide (peers discover and sync documents across the Seed network)
Content Addressing Yes (documents and changes are content-addressed; IPFS CID-compatible)
Local-First Local-First (daemon stores all data locally; sync happens when peers are available)
E2EE No (data is signed but not encrypted end-to-end by default)
CRDTs Lib Custom CRDTs (custom HLC-based block-level CRDTs for document editing)
Byzantine Fault Tolerance No (relies on cryptographic identity verification, not BFT consensus)
Signature Ed25519 (keypair-based identity for document authorship and authentication)
Permissions Cryptographic Capabilities (document owners control who can edit via key-based authorization)
Semantic Web Compatibility Links (documents support typed hypermedia links and entity references but not full RDF)
Smart Contract No
Protocol Stack Position Application-layer (built on TCP/IP)
Asset / Value Embedding None — Seed Hypermedia (formerly Mintter) is a P2P document and knowledge-graph platform with no native protocol token. The project is VC-funded; no tokenized economic layer is defined in the protocol.
Protocol Maturity / Standardization Community Standard (open protocol specification; built on Hypercore/Hyperswarm ecosystem)
