Herbees
Scalable intermediated P2P messaging based on Simplex Messaging protocol
Herbees is an independent, unofficial, community-focused, open-source Rust implementation of the Simplex Messaging Protocol (SMP). It's designed as a robust and scalable foundation for relay-intermediated communication applications (intermediated p2p). Built upon the protocol’s elegant threat model and design principles established by the ingenious creators of SMP, Herbees provides middleware libraries and a high-performance SMP relay server. It also includes a reference, minimalistic CLI client to inform client developers how to construct user-centric clients and decentralized applications that leverage the protocol and its features – secure, authenticated, end-to-end encrypted (E2EE), private message exchanges – without requiring direct peer-to-peer connectivity or metadata exposure.
This project was funded through the NGI0 Commons Fund, a fund established by NLnet with financial support from the European Commission's Next Generation Internet programme, under the aegis of DG Communications Networks, Content and Technology under grant agreement No 101135429. Additional funding is made available by the Swiss State Secretariat for Education, Research and Innovation (SERI).
