Ixian S2 is the decentralized, trustless data transmission and streaming layer of the Ixian Platform. It enables real-time communication, presence-based discovery, and streaming services on top of Ixian DLT.

S2 is designed for the next generation of decentralized applications, from secure messaging to IoT networks, with built-in support for scalable presence and fair monetization models.

Ixian S2 is built to replace centralized communication servers with a decentralized overlay network that scales.

• 🕸️ Presence-based Communication - Users and devices are discovered via cryptographic addresses, not IP or DNS. Presence packets (signed and time-limited) ensure authenticity and freshness without SSL/TLS or certificate authorities.

• 🕊️ Starling Presence Scaling Model - A sector-based scaling architecture where S2 nodes are grouped into relay sectors. This enables efficient lookups, low overhead, and scalability to trillions of devices.

• 💰 Incentives for Node Operators - S2 nodes are economically incentivized. Operators earn relay rewards for transactions they forward into the DLT network, via a dual fee model (DLT network fee + S2 relay fee). This ensures fair distribution, aligned incentives, and long-term sustainability.

• 🔒 Secure & Trustless - Every connection is authenticated cryptographically. Identities, presence, and discovery are self-authenticated, making external trust systems unnecessary.

• �� Low Latency, High Throughput - Optimized for real-time streaming, messaging, and dApps, even under global load.

• ♻️ Resilient by Design - Decentralized, fault-tolerant architecture with no downtime or single points of failure.

Unlike traditional networks where discovery relies on DNS/IP, SSL certificates and central directories, Ixian uses cryptographic addresses and presence packets. This eliminates the need for external trust systems.

Lifecycle of a client lookup:

1. Initiation - User A wants to connect to User B, knowing only B's Ixian cryptographic address.

2. Sector Resolution - User A sends a Get Sector request to its connected S2 node. The S2 node queries the Ixian DLT to determine which sector User B belongs to (DLT tracks all active S2 base presences).

3. Presence Request - User A queries one of the S2 nodes in User B's sector for User B's presence packet.

4. Presence Packet - If User B is online, the S2 node returns B's signed presence packet, which contains:

   • Timestamp (to prevent replay and confirm freshness),
   • Contact details (IP/transport endpoint, with support for non-IP in the future),
   • Signature from User B's private key proving authenticity.

5. Communication Setup - User A now knows how to communicate with User B:

   • Directly (if reachable and if User B chooses to reveal their direct communication channel publicly),
   • Or indirectly (via relay/TURN functionality provided by S2 nodes if behind NAT/firewall).

6. Keep-alive cycle - User B must refresh its presence every few minutes with a new timestamp + signature, or the presence expires automatically.

• 🔑 No centralized SSL/TLS infrastructure required - trust comes from cryptographic signatures, not certificate authorities.
• 🕸️ Lookup by cryptographic address - eliminates DNS and central directories.
• ⚡ Scalable by design - the Starling model and sectorized presence make discovery efficient, even at trillion-device scale.
• 🔒 Always authentic, always fresh - signatures + expiry guarantee that presence data can't be spoofed or reused.
• ♻️ Future-ready - supports both Internet-based IP and non-IP addressing models.

Ixian S2 turns discovery and communication into a cryptographically verifiable, decentralized service - future-proof by design.
