We are thrilled to announce that the Universal Integrated Identity Decoupled (UIID) system has officially moved to a stable release and is accessible to all customers today, October 10, 2025.
You can now access the full, stable UIID experience at: 🔗 uiid.linkspreed.com
This stable version will receive only tested, production-ready updates. All live development and feature testing occur in a separate development environment, ensuring a reliable and consistent experience for you.
The UIID is a foundational technology designed to eliminate the long-standing privacy trade-off of the modern internet. It represents the core pillar of Web4—a new, user-centric internet built on trust, privacy, and personal control.
UIID puts you, the user, in absolute, non-negotiable control of your entire digital identity. It's much more than just a new way to log in.
For decades, using the internet meant surrendering ownership of your digital self. This created three major risks:
Endless Risk: Your personal information is spread across numerous corporate servers, creating large, attractive targets for hackers and data breaches.
Password Vulnerability: Simple passwords are the single weakest link, easily forgotten, guessed, or stolen through phishing attacks.
You Are the Product: Many business models rely on constantly tracking, linking, and monetizing your private information and browsing habits without your full knowledge or consent.
UIID implements Self-Sovereign Identity (SSI), which is an irreversible transfer of power back to the individual.
You Are the Owner: Your digital identity is stored securely in your private Identity Vault (your digital wallet), never on a central corporate server.
Existential Portability: Your core ID, credentials, and reputation proofs are no longer locked into any single platform. You can take them with you across services, platforms, and even into future virtual worlds without starting from scratch.
Privacy-Sanitized DLT: UIID uses Decentralized Ledger Technology (DLT) only as a secure, public notary register to confirm the unique existence and status of your ID. Crucially, no Personally Identifiable Information (PII) is ever stored on the public ledger.
UIID uses advanced architectural and cryptographic methods to ensure your identity remains private and secure:
Component | What it is | How it Protects You |
|---|---|---|
Identity Vault | Your secure, personal application on your device. Think of it as your "Digital Soul." | Stores the cryptographic keys for your Core ID and all digital proofs (Verifiable Credentials), ensuring they never leave your control. |
Decoupled Architecture | The fundamental separation between your high-trust root identity and your everyday online activity. | Ensures third parties cannot cryptographically link your anonymous online actions back to your real-world identity. |
Zero-Knowledge Proofs (ZKP) | An advanced mathematical technique. | Allows you to prove a fact (e.g., "I am over 18") without revealing the underlying source data (your birth date, name, etc.). |
