The 4 Pillars of a Legal Digital Seal

Basic PDF workflows leave gaps in compliance and version control. StampOnChain uses Zero-Knowledge cryptographic hashing to guarantee your compliance with strict Board rules.

1. Unique Identity

Cryptographically tied to your specific PE license, making forgery mathematically impossible.

2. Independent Verification

Reviewers can verify authenticity via a URL/QR code instantly, without needing special software.

3. Sole Control

Zero-knowledge architecture means nobody—not even us—can apply your seal but you.

4. Tamper-Evident

If a subcontractor changes one pixel of your PDF, the hash breaks, invalidating the seal instantly.
