A comprehensive enterprise guide to decentralized identity and verifiable credentials covering the core architecture (DIDs, W3C VCs, ZKPs, digital wallets), the three-party trust model, and the EU's eIDAS 2.0 regulatory deadlines requiring EUDI Wallet support by end of 2026. Covers proven ROI use cases including reusable KYC, employment/credential verification, marketplace trust, and emerging AI agent identity. Includes a comparison of centralized vs. federated vs. self-sovereign identity models, a phased 9-month implementation roadmap, and practical guidance on technology selection (enterprise CIAM platforms, open-source libraries). Also addresses ZKP-based privacy-preserving verification for GDPR compliance and answers common questions on blockchain requirements, revocation mechanics, and deepfake resistance.
