A Five Stage Protocol Handling Decentralized Sync and Communication
Yuuko Protocol is a decentralized protocol created for the XRUIOS; it uses "The Holy Mother", an orchestrator, to handle a multitude of datastreams like files, realtime data, messages and even videos alongside syncing.
Cross Platform • Internet, Wifi Direct or Wired • Post Quantum Computing Resistant • No BS
Core Features Planned
- "The Holy Mother", handles creating and managing application streams automatically
- Nintendo Streetpass style communication between devices, minimal bandwidth and high count support
- XMPP based notifications
- WebRTC + Facade (WIP) Based Interaction And Video Streaming
- Event Sourcing - Trust and Permissions
- CRDT System - Realtime UI and States
- Git Style System - File and Assets
- AES-256-GCM for request/response payloads
- Hard for third-party processes to inject or read traffic
- Designed for local-first scenarios (desktop apps ↔ local LLMs ↔ tools ↔ services)
- No central server required beyond the machine itself

Measured performance (in-process; excludes network)
| Metric | Result |
|---|---|
| Post-quantum handshake + first request | ~2.4 ms/peer (one-time) |
| Warm request round-trip (serial) | ~54 µs → ~18,500 req/s |
| Throughput (concurrent, 8–32 lanes) | ~33–40k req/s |
| Raw AES-256-GCM enc+dec (256 B) | 3.6 µs/op → ~280k op/s |
Requirements
The following (Free, Open Source Solutions on our Github) libraries are required for this to workl

Stages
- Zenoh C# Based API Created
- Eclipse-Secured Handshake + Per-Peer Encrypted Sessions (Kyber-1024 + AES-256-GCM)
- Multiplexed Lanes (parallel encrypted requests per peer)
- Connected Endpoints Handler
- CRDT Handler
- Operational Transformation Handler
- Event Sourcing Handler
- Git Style DAG + Keeper Of Tomes
- Service Handler
- Trust Based Sync Visibility
- Easy BLE/Wifi Handling
- P2P Mesh (Secure) — secure core done; discovery/replication pending
Security (Implemented)
Built and benchmarked — see 1 - System Design for numbers (~2.4 ms post-quantum handshake, then ~54 µs warm request round-trips; the crypto is effectively free).
- Enrollment → registers client ID + PSK
- Handshake → Kyber-encrypted key exchange → shared secret
- Session → AES-256-GCM + per-message nonces
- Transcript → HMAC-protected log of handshake messages → prevents downgrade & MITM
- Designed to resist classical & quantum adversaries (where Kyber helps)
