The system solves the problems of data privacy, user control, and security in digital services. It harnesses the power of blockchain technology to remove centralized powers, creating a trustless security framework free from single points of failure. Custom access control policies can managed by the users themselves, preventing exposure of sensitive data to third parties.  

Data access within the system is protected with symmetric encryption and proxy re-encryption. These measures block access to unauthorized entities. Protective measures against data corruption are used to ensure the integrity of data stored within the system. These advancements show the possibilities available from decentralized systems operating in trustless frameworks that bolster user privacy while fortifying the security of the information.
