Yuuko Protocol

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)
