ProofSpace

ProofSpace is a no-code platform for implementing Self-Sovereign Identity (SSI) solutions, launched in 2022 by ZAKA Group Ltd. The platform enables organizations to build and scale decentralized identity workflows through its core product SSI OAuth, which provides peer-to-peer single sign-on capabilities enhanced with verifiable credentials. The system implements key SSI principles including W3C Verifiable Credentials and focuses on privacy-preserving features like selective disclosure and zero-knowledge proofs.

The platform consists of two main components: a web-based ProofSpace Dashboard for organizations to configure identity workflows without coding, and the ProofSpace App - a mobile wallet for users to store and manage their credentials. Key technical features include peer-to-peer communication, local encrypted storage of personal data, and integration capabilities through webhooks. The system supports verification of social accounts and identity documents across 230+ countries while maintaining user privacy through features like:

• Data minimization through selective disclosure
• Zero-knowledge predicates for private verification
• No intermediary storage of shared credentials
• Consent-driven peer-to-peer interactions

Notable implementations and partnerships include:

• Collaboration with the Japanese Government on decentralized identity
• Integration with NHTI for issuing educational credentials
• Certification by ID2020 for meeting technical and ethical standards
• Work with blockchain platforms like Cardano for Web3 identity solutions
