Transform GenoBank.io from a closed ecosystem requiring pre-registered laboratories into an open platform where anyone can register ANY biosample tube, creating a public notarization system for biosample ownership and consent.

Recommendation: Migrate to Privy for superior non-Web3 user experience and passkey support.
User Journey:
1. Scan ANY tube barcode →
2. Select/Search company →
3. One-click registration →
4. BioNFT created →
5. Email confirmation

Subject: ✅ Your biosample has been registered!
Hi [Name],
You've successfully registered your biosample:
- Barcode: [BARCODE]
- Company: [COMPANY]
- Date: [DATE]
- BioNFT ID: [ID]
What's next?
1. When you receive results, upload them to GenoBank
2. Access AI-powered analysis tools
3. Control who can access your data

This improved system transforms GenoBank from a closed B2B2C platform into an open B2C platform where anyone can register any biosample, creating the world’s first universal biosample ownership registry. By using passkeys and progressive disclosure, we make Web3 invisible to users while preserving its benefits of ownership, consent, and transparency.
