PoArt Protocol is a trustless, client-side notarization system for digital assets.
It allows creators and collectors to generate immutable cryptographic proofs of authenticity — directly in the browser.
- Architecture: 100% client-side (Serverless)
- Cryptography: Dual SHA-256 & SHA-512 hashing
- Timestamp: UTC-based
- Rendering: Real-time PNG certificate (
html2canvas) - Database: Supabase (PostgreSQL + JSONB)
- Privacy: No IP or location tracking
- Device Info: Client-side only
- Focused on speed and frictionless UX
- Supabase-based manifest registry
- Real-time certificate generation
- IPFS + Arweave support
- Immutable storage and trustless verification
