Decentralized Identity Verification

MicrocosmWorks implements self-sovereign identity (SSI) architectures where users store their verified credentials (age, citizenship, professional licenses, education) in a personal wallet on their device, and only share zero-knowledge proofs or selective disclosure of specific attributes with requesting services — the central system stores only cryptographic proofs, never the actual personal data. Verification happens peer-to-peer between the user's wallet and the relying party, with the blockchain serving only as a trust registry for issuer public keys and credential revocation status. This means there is no honeypot database to breach, fundamentally eliminating the class of centralized data breach vulnerabilities.

MicrocosmWorks builds on W3C Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) standards, ensuring interoperability with any compliant wallet, issuer, or verifier in the growing global SSI ecosystem including Microsoft Entra Verified ID, Hyperledger Aries, and Dock. The system supports multiple DID methods (did:web, did:ion, did:key) to balance between decentralization purity and practical deployment considerations, and credentials are encoded in JSON-LD or JWT format for broad compatibility. Standards-based implementation protects your investment from vendor lock-in and ensures your identity system can participate in emerging cross-industry verification networks.

MicrocosmWorks implements a trust triangle model where recognized authorities (governments, universities, licensing boards, employers) issue digitally signed verifiable credentials to individuals, who store them in their personal wallets and present them when verification is needed. The verifier checks the cryptographic signature against the issuer's public key (published on-chain or on did:web) to confirm authenticity without contacting the issuer directly. For bootstrapping credential issuance from existing paper documents, MicrocosmWorks integrates with identity verification providers that perform initial document authentication and biometric matching before minting the digital credential.

MicrocosmWorks deploys decentralized identity for mainstream use cases including age verification for e-commerce and entertainment (without revealing birth date or address), employee credential portability between organizations, healthcare provider license verification across state lines, education credential verification for hiring, and KYC reuse where a single bank verification can be accepted by other financial services. The technology is particularly valuable for cross-border scenarios where centralized databases do not exist, such as refugee identity and displaced worker credential verification. Enterprise deployment typically runs $25-$50/hr for development and integration with existing identity management systems.

MicrocosmWorks implements credential revocation using privacy-preserving mechanisms like revocation registries (based on cryptographic accumulators) where the issuing authority can revoke a credential without revealing the identity of the holder. When a verifier checks a presented credential, they simultaneously check the revocation registry to confirm the credential has not been revoked since issuance. The system supports both immediate revocation for cause (license suspension) and time-based expiration for routine renewals, with configurable grace periods and renewal notification workflows for credential holders.
