Issue Tamper-Proof Government Documents at Scale
From birth certificates to land titles, government documents are the foundation of civil society. Protect them with cryptographic anchoring that makes forgery impossible.
Document Fraud Undermines Public Trust
Forged government documents enable identity theft, property fraud, illegal immigration, and corruption. Traditional security measures like holograms and watermarks are increasingly defeated by modern printing technology. Citizens and institutions need a reliable way to verify document authenticity.

How It Works
Issue Documents
Government agencies issue documents through Sealayer. Each document receives a unique cryptographic hash and QR code at the point of creation.
Blockchain Anchoring
The document hash is anchored to the Polygon blockchain with an RFC 3161 timestamp, creating an immutable record that cannot be altered or backdated.
Public Verification
Citizens, employers, or any third party can verify a document instantly by scanning the QR code or entering the hash. No login required.
Frequently Asked Questions
How can government agencies start issuing tamper-proof documents?
Sealayer provides both API integration and a web dashboard. Agencies can integrate directly with existing document management systems or use the dashboard to issue and anchor documents manually.
Can citizens verify documents without creating an account?
Yes. The verification endpoint is completely public and free. Anyone can verify a document by scanning its QR code or entering the document hash on the Sealayer verification portal.
How does this prevent forged birth certificates and land titles?
Every document issued through Sealayer has a unique cryptographic fingerprint anchored to the blockchain. Any modification to the document -- even a single pixel -- changes the hash, making forgeries instantly detectable.
Is the system GDPR compliant for handling citizen data?
Yes. Sealayer stores only the cryptographic hash of documents, not the document contents themselves. Personal data remains under the control of the issuing agency. The system includes full GDPR compliance tools including data export and erasure.
Can this work at national scale with millions of documents?
Absolutely. Sealayer uses batch anchoring to efficiently process high volumes. Multiple documents are grouped into Merkle trees and anchored together, making it both cost-effective and scalable to millions of documents per month.
