Decentralized Identity Mesh
A zero-knowledge proof-based identity system that allows users to prove attributes about themselves without revealing underlying personal data, running on a distributed network with no central authority. Vision Replace traditional identity verification with cryptographic proofs - verify you’re over 21 without revealing your birthdate, prove income without showing bank statements, confirm credentials without exposing education history. Core Features Zero-Knowledge Proofs: Prove facts without revealing data Self-Sovereign: Users control their own identity data Verifiable Credentials: Cryptographically signed attestations Privacy-Preserving: Selective disclosure of attributes Interoperable: Works across different platforms and jurisdictions Technical Stack Blockchain: Ethereum or Polygon for credential registry Cryptography: zk-SNARKs for zero-knowledge proofs Storage: IPFS for encrypted identity documents Standards: W3C Verifiable Credentials, DID (Decentralized Identifiers) Architecture Identity Layer Decentralized identifiers (DIDs) Key management and recovery Biometric anchoring (optional) Credential Layer Issuer registry Credential schemas Revocation lists Timestamp verification Verification Layer Proof generation Proof verification Selective disclosure Predicate proofs (age > 21, income > X) Use Cases Age Verification: Prove age without revealing birthdate Income Verification: Rent apartments or loans without bank statements Educational Credentials: Verify degrees without transcripts Healthcare: Share specific medical information with providers Voting: Anonymous yet verified voting systems Travel: Border crossing without revealing full passport data Privacy Features Minimal Disclosure: Share only what’s necessary Unlinkability: Different verifiers can’t correlate activities Consent-Based: Explicit user approval for each disclosure Revocable: Users can revoke credentials anytime Auditable: Cryptographic proofs of all transactions Challenges User experience vs security tradeoff Recovery mechanisms for lost keys Regulatory compliance (GDPR, KYC/AML) Adoption by credential issuers Performance of zero-knowledge proofs Unique Innovations Reputation Layer: Build trust without revealing identity Credential Marketplace: Trade anonymized data insights Social Recovery: Trusted contacts can help recover access Progressive Disclosure: Reveal more information over time Impact Restore privacy in digital interactions Reduce identity theft and fraud Enable new privacy-preserving services Comply with data protection regulations Empower individuals with data ownership
