Certopus

Certopus is a digital credentials platform launched in 2022 that enables organizations to issue and manage verifiable digital certificates and badges. The platform implements W3C Verifiable Credentials and Decentralized Identifiers (DIDs) through its integration with Polygon ID, transitioning from NFT-based certificates to standards-compliant verifiable credentials. Key technical features include:

• Credential Management System with:
  • Template-based certificate design engine
  • Bulk issuance capabilities
  • Automated delivery via email
  • Zero-knowledge proof verification
  • Selective disclosure controls
  • Integration with popular Learning Management Systems

The platform has evolved its technical architecture through a significant collaboration with Polygon ID announced in November 2023, implementing self-sovereign identity principles and blockchain-based verification. This integration enables credential holders to maintain control over their digital identity while allowing verifiers to cryptographically validate credentials without relying on centralized authorities. The platform supports both traditional email-based identity and DID-based identity management, with the latter providing enhanced privacy and security features.

Notable adoption includes over 1,200 organizations using the platform for issuing digital credentials across educational institutions, training programs and professional certifications. The platform maintains interoperability through support for standards like OpenBadges and provides APIs for integration with third-party systems. Certopus positions itself as a bridge between traditional digital credentials and Web3 identity infrastructure, focusing on enterprise adoption of verifiable credentials while maintaining user privacy through selective disclosure capabilities powered by Polygon ID's zero-knowledge technology stack.
