About MeshBay

MeshBay is a decentralized, peer-to-peer platform for file sharing, video streaming, and group messaging. It combines identity federation (via Mesh Hubs) with truly peer-to-peer data exchange (via Mesh Nodes).

Architecture

The system has three components:

• Mesh Hub — a lightweight identity authority and group registry. It stores user accounts and group metadata, but never touches content.
• Mesh Node — runs on the host user's machine. It stores and serves all files, streams, and chat messages directly to group members.
• Mesh Client — a web browser or Android app. Connects directly to nodes for all data transfer. The hub is never in the data path.

Security

Private groups use end-to-end encryption with ChaCha20-Poly1305. Authentication uses Ed25519 signed JWTs. Key exchange is based on X25519 ECDH with HKDF. Passwords are hashed with Argon2id (64 MiB).

Open Source

MeshBay is open source. The code is available on GitHub.
