Enabeling selective disclosure mechanisms in blockchain systems empowers users to share only the necessary data with specific parties, thereby enhancing privacy and control over personal information. This approach allows individuals to reveal specific attributes or credentials without exposing their entire data set. For instance, the IU-SmartCert system enables users to selectively disclose components of their academic credentials, ensuring that only relevant information is shared with verifiers. Similarly, the SeDe framework balances privacy and regulatory compliance by allowing selective de-anonymization in blockchain transactions. By incorporating such selective disclosure techniques, blockchain platforms can uphold user privacy while maintaining the integrity and utility of the shared data.
