Blockchain KYC (Know Your Customer) leverages decentralized systems to streamline and secure the customer verification process. By using blockchain, organizations can create a single, immutable digital identity for users, reducing the need for repetitive verification across different services. This improves efficiency, ensures privacy, and minimizes fraud. Blockchain KYC solutions provide real-time access to verified identity data while offering customers greater control over their personal information, benefiting financial institutions and businesses in compliance-heavy sectors.
