Decentralized Identity Services
Comprehensive solutions for self-sovereign identity and verifiable credentials
Self-Sovereign Identity Systems
Complete identity frameworks that put users in control of their personal data with secure, portable digital identities.
Verifiable Credentials Infrastructure
Systems for issuing, holding, and verifying digital credentials with cryptographic proof and selective disclosure.
Zero-Knowledge Verification
Privacy-preserving verification systems that confirm information without revealing sensitive data.
Enterprise Identity Integration
Decentralized identity solutions that integrate with existing enterprise systems, compliance frameworks, and user directories.
Decentralized Identity Standards & Frameworks
Key technical protocols and frameworks powering modern identity solutions
W3C Decentralized Identifiers (DIDs)
Globally unique identifiers created and controlled by the identity owner without requiring central registration. Our implementations follow the W3C DID Core specification for permanent, cryptographically-verifiable identifiers.
Verifiable Credentials (VCs)
Standardized containers for expressing credentials in a cryptographically secure, privacy-respecting, and machine-verifiable way. Our implementations enable secure digital representations of credentials with tamper-evident properties.
Decentralized Key Management
Secure and user-friendly systems to generate, store, and recover cryptographic keys used in decentralized identity. We implement standards like WebAuthn, KERI, and DIDComm for verifiable key management.
OIDC & OAuth Integration
Implementation of OIDC4SSI (OpenID Connect for Self-Sovereign Identity) and SIOP (Self-Issued OpenID Provider) to bridge decentralized identity with existing authentication frameworks.
Zero-Knowledge Proofs (ZKPs)
Advanced cryptographic techniques enabling selective disclosure of identity attributes without revealing underlying data. Our implementations use BBS+ signatures and other ZK systems for privacy-preserving verification.
DIDComm Messaging
Secure, private communication protocol between DID-identified entities. Enables encrypted, authenticated messaging for credential exchange, verification, and general communication between identity wallets and services.
Identity Protocol Comparison
Comparing different approaches to decentralized identity implementation
| Protocol | Architectural Approach | Privacy Features | Key Management | Implementation Complexity | Best Use Cases |
|---|---|---|---|---|---|
| Self-Sovereign Identity (SSI) | Fully decentralized with user-controlled identifiers, credentials stored in personal wallets, and peer-to-peer verification | High - Selective disclosure, zero-knowledge proofs, user consent for all data sharing | User-managed with recovery methods (social, hardware, custodial options) | High - Requires significant user education and new infrastructure | Healthcare records, government credentials, professional certifications, cross-border identity |
| Federated Identity + Verifiable Credentials | Hybrid approach using existing identity providers with blockchain-verified credentials | Medium to High - Depends on implementation, potential correlation risks | Partially delegated to identity providers with user-controlled aspects | Medium - Builds on existing systems with new credential layer | Enterprise identity, regulated industries, backward compatibility needs |
| On-Chain Identity | Identity linked directly to blockchain addresses, with on-chain credential registry and verification | Low to Medium - Public blockchain data with encryption options | Blockchain wallet key management, often single key with recovery challenges | Medium - Familiar to blockchain users but limited privacy features | Web3 authentication, DAO participation, on-chain reputation systems |
| Zero-Knowledge Identity | Privacy-first approach using zero-knowledge proofs for all identity assertions | Maximum - Mathematical guarantees of minimal disclosure | Complex cryptographic key management with specialized hardware support | Very High - Requires advanced cryptography implementation | Financial KYC, age verification, credential verification without data sharing |
| Biometric + Blockchain | Biometric verification with blockchain attestation and secure templates | Medium - Depends on biometric implementation and storage approach | Biometric factors generate/unlock keys, often with device-specific security | High - Requires specialized hardware and biometric security expertise | Physical access control, high-security verification, seamless authentication |
| Hierarchical Identity | Structured identity issuance through trusted authorities with verification chains | Low to Medium - Authority-aware model with potential for tracking | Hierarchical with root authorities and delegated issuance keys | Medium - Similar to existing PKI models with added features | Corporate identity, compliance-focused scenarios, trusted authority models |
