# iroh-gossip

This crate implements the `iroh-gossip` protocol.
It is based on *epidemic broadcast trees* to disseminate messages among a swarm of peers interested in a *topic*. 
The implementation is based on the papers [HyParView](https://asc.di.fct.unl.pt/~jleitao/pdf/dsn07-leitao.pdf) and [PlumTree](https://asc.di.fct.unl.pt/~jleitao/pdf/srds07-leitao.pdf).

The crate is made up from two modules:
The `proto` module is the protocol implementation, as a state machine without any IO.
The `net` module connects the protocol to the networking stack from `iroh-net`.

The `net` module is optional behind the `net` feature flag (enabled by default).
