Jami

StatusStableReviewdue UpdatedStands on2 sourcesSupportsnotes

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 conversations

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 boundary

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.
