What you can do with sovereign data.

Store tax records, medical history, legal documents, passwords, or family heirlooms encrypted on IPFS. No company can access them, and ownership is cryptographically proven via NFT. Ideal for anyone who does not trust centralized platforms with their most sensitive data.

Share vacation photos, home videos, or financial spreadsheets with family using time-limited decryption access. Recipients can view files only for the duration you allow — no permanent copy unless you explicitly permit it. No real identity required, just a decentralized ID.

Store wills, funeral instructions, crypto seed phrases, or final messages. Smart contract rules can grant access to loved ones only after specified conditions are met, with no lawyer or bank required as an intermediary.

Independent creators — writers, photographers, musicians, 3D artists — upload original files. The NFT proves ownership of the master. Sell temporary access directly to fans without surrendering a platform cut or your rights.

Researchers, students, and hobbyists can share notes, datasets, or project files with collaborators without linking files to their real-world identity. Well-suited for privacy-conscious users or those operating in restrictive environments.

Store contracts, proprietary designs, source code, or financial models and grant temporary access to partners, clients, or auditors — without uploading to a central server that could be breached or subpoenaed. Access can be sold directly as a time-limited license.

Patients control their own encrypted health records and grant temporary decryption access to doctors, specialists, or insurers only when needed. The NFT proves record ownership, and decentralized IDs eliminate massive centralized databases vulnerable to breaches.

Law firms, inventors, and studios store patents, screenplays, music masters, or game assets. The NFT acts as a tamper-proof certificate of authenticity. Access to the underlying files can be sold or licensed, making it easy to prove original authorship in disputes or commercial negotiations.

Store deeds, surveys, inspection reports, and closing documents. Buyers and sellers use temporary access during transactions, and the NFT can represent the property title itself. Reduces reliance on title companies and accelerates cross-border transactions while maintaining privacy.

Scientists and universities store raw datasets, lab results, or papers and sell temporary access to other researchers or journals. Decentralized IDs allow collaborators to remain pseudonymous. Data persists on IPFS permanently and cannot be altered or taken down.

Journalists and insiders securely upload evidence or leaked documents, proving ownership via NFT while maintaining anonymity through decentralized IDs. Temporary access can be granted to newsrooms or fact-checkers without relying on centralized infrastructure vulnerable to takedown requests.

Web3 applications and startups can use Signet as the storage layer for user-generated content — a decentralized content marketplace, private messaging platform, or stock media library. Developers get native support for selling access to premium files or datasets.
