Seed Hypermedia
P2P ProtocolsA 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

P2P Protocol Attributes
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 Compatability 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)
