JamiCopy wiki link

Jami is a peer-to-peer communication application and protocol stack for messaging, group chat, calls, file transfer, and multi-device accounts. It uses a DHT for discovery and direct authenticated connections rather than federated homeservers.

Swarm conversationsCopy wiki link

Jami calls its decentralized group conversations swarms. Each conversation is represented by a signed Git repository; the first commit identifies the conversation, and participants synchronize and validate later commits directly. This supports network partitions and later history merging without a central group authority.

The design makes history durable and independently verifiable. Its documentation describes PFS for transport channels, while conversation history is stored on participant devices. That is different from a ratcheted message protocol that continually erases old message keys.

Interoperability boundaryCopy wiki link

Jami defines one integrated network and conversation model. Its platform clients interoperate through the shared Jami daemon and protocols, A new implementation would have to reproduce Jami’s account certificates, discovery, peer connection, swarm repository, validation, and synchronization behavior.

Secure and decentralized communication stacks places this integrated peer-to-peer model within the wider secure-communications landscape.
