CorpoSign DID

CorpoSign DID is a decentralized identity wallet application developed by Systems Integration Solutions in Lithuania that enables users to manage verifiable credentials using blockchain technology. The solution is fully conformant with W3C DID and EBSI (European Blockchain Services Infrastructure) standards for decentralized identifiers and verifiable credentials.

The wallet's core features include:

• Storage and management of verifiable credentials
• Generation of verifiable authorization presentations
• Integration with OpenID Connect for authentication
• Support for business and government power of attorney credentials
• Implementation of Zero-Knowledge Proofs for privacy-preserving verification

Launched in 2022, CorpoSign DID has received notable recognition through the eSSIF-Lab program and is one of three officially supported wallets for the European Social Security Pass (ESSPASS) initiative. The wallet is being used to enable cross-border verification of social security entitlements, with a focus on the Portable Document A1 credential. Key implementations include:

• Integration with ESSPASS for managing social security credentials
• Adoption by Lithuanian government agencies for legal person identification
• Support for student identification and diploma credentials at educational institutions

The project leverages the European Blockchain Services Infrastructure as its trust framework and aims to advance Self-Sovereign Identity adoption across Europe through compliance with eIDAS 2.0 regulations and interoperability with other SSI solutions.
