Shahaf Bar-Geffen, CEO of COTI, asserts that blockchain privacy is essential for the mass adoption of Web3. He highlights a significant privacy issue inherent in public blockchains, where data becomes accessible once transmitted. This transparency poses risks, especially in decentralized applications (dApps), where sensitive data cannot remain private. Bar-Geffen emphasizes the importance of privacy, not just as a principle but as a legal requirement for organizations, particularly in decentralized finance and real-world assets, where confidentiality is crucial. COTI's approach uses a unique cryptographic method that allows interaction with encrypted data without decryption, offering advantages over traditional homomorphic encryption. Furthermore, Bar-Geffen distinguishes between privacy and anonymity, arguing for a model that allows for selective disclosure, enabling compliance with legal standards while maintaining privacy.
