Summary

Web3’s decentralization, immutable blockchains, and self-sovereign identity model create tensions with GDPR requirements for accountable data controllers, revocable consent, and the right to erasure, particularly in DAOs and public ledgers. Developers can address these challenges through privacy-by-design practices such as collecting minimal data, keeping sensitive information off-chain in encrypted storage, providing clear consent and rights-management processes, and using pseudonymization, verifiable credentials, and zero-knowledge proofs to validate attributes without exposing underlying personal details. Self-sovereign identity can support GDPR’s emphasis on user control, while clear responsibility for data processing remains necessary even in decentralized systems. The text presents Didit as an identity and compliance orchestration platform offering modular verification, reusable KYC, privacy-focused biometric processing, workflow tools, and certified compliance infrastructure intended to reduce the complexity of building GDPR-aligned Web3 applications.
