Question: Is there a system that allows users to prove specific information without revealing underlying data, ensuring compliance with data privacy regulations?

Dock is a powerful foundation for creating trusted, reusable digital ID credentials based on verifiable data. It offers instant verification with QR codes, support for multiple digital wallets, and zero-knowledge proofs for data privacy compliance. Dock is GDPR compliant and doesn't store personal data on the blockchain, making it a good option for industries like health care, finance and education.

Another good option is Reclaim Protocol, which uses zero-knowledge proof digital signatures to establish identities based on online activity. It can improve HTTPS security with cryptographic proof of data integrity, support Know Your Customer (KYC) verification, and offer on-chain attestations. It's a decentralized protocol that can be used for a variety of applications, including identity and DeFi products.
