Project Description

What did you build? Describe your use case.
We built NillionVault, a production-ready secure message storage platform powered by the Nillion Network.
It allows users to store, verify, and manage encrypted messages using Nillion SecretVaults for end-to-end encryption and nilChain blockchain anchoring for immutable proof of existence.

🔗 Live App: https://nillionvault-frontend.onrender.com/

🔗 Backend API: https://nillionvault-backend.onrender.com/

Use cases include:

Secure note storage

Password and credential management

Secret message sharing

Immutable proof of communication

Compliance and data integrity verification

What problems does your project solve? How does it preserve privacy for users?

roblem 1: Traditional cloud or database storage exposes sensitive messages to centralized systems or admins.
✅ Solution: NillionVault stores messages end-to-end encrypted inside Nillion SecretVaults, ensuring only the user with the proof hash can decrypt them.

Problem 2: Verifying message authenticity and existence often depends on centralized authorities.
✅ Solution: Each stored message is anchored on the nilChain blockchain, creating an immutable cryptographic proof of existence.

Problem 3: Privacy-first systems often lack usability.
✅ Solution: NillionVault offers a clean, modern UI with metadata-only listings — meaning message content is never exposed or previewed unless verified.

Privacy Preservation:

Only encrypted %allot content is stored in Nillion’s decentralized network.

No plaintext messages ever touch centralized storage.

Verification and decryption require the user’s unique proof hash.

No external databases — 100% Nillion-native architecture.

How does the project use Nillion? Describe and link to any Nada programs

e used Nillion for:

Secure message encryption & storage using Nillion SecretVaults API

Distributed message retrieval from the Nillion testnet nodes

Cryptographic proof anchoring via the nilChain blockchain

Keyless verification and proof generation using SHA-256 + Nillion hybrid storage

Nada program(s) used:

Nillion SecretVaults

Nillion Authentication (NILAuth)

Nillion nilChain Anchoring

Is there anything else you want to share?

We’re planning to extend NillionVault with:

🧩 File upload support (PDF, DOCX, JSON)

📱 Mobile UI for on-the-go encryption

⚙️ Enhanced analytics and dashboarding

🔐 User-level secret sharing using multi-party computation (MPC)

🪲 Currently, no major bugs — only minor latency issues during high concurrent uploads.

Support requested:
We’d love access to improved testnet bandwidth and SecretVault SDK updates to handle larger encrypted payloads for enterprise-level use cases.
