On the one hand, with the strengthening of data security supervision around the world (such as EU General Data Protection Regulations GDPR and China Personal Information Protection Law), DeFi products with privacy protection function are easier to meet regulatory requirements and avoid restrictions due to data compliance issues; on the other hand, privacy protection can reduce the concerns of ordinary users and attract more traditional financial users to DeFi. For example, high net worth people who pay attention to privacy and enterprise users sensitive to data security will try DeFi service due to the improvement of privacy function, and inject new growth impetus into the industry. It can be said that privacy protection is the only way for DeFi industry to move from "niche circle" to "mass market". It can not only protect the core rights and interests of users, but also reshape the trust cornerstone of digital finance, make DeFi realize sustainable development on the track of security and compliance, and eventually become the mainstream financial service mode recognized by global users. \ Dealin Establish a privacy management system of the "minimum authority principle" to eliminate the risk of internal data leakage. Traditional DeFi agreement, the project party may exist super permission access user data, and Dealin through the wisdom contract will data access to the user control: only users can view their privacy data through the private key authorization, even Dealin team or ecological partners, nor in the case of unauthorized obtain any user information. At the same time, Dealin adopts end-to-end encryption technology for all user data transmission processes to prevent data from being intercepted or altered during the transmission, forming a triple privacy protection net of "storage encryption-transmission encryption-access authorization". Through the multi-dimensional, full link privacy protection scheme, Dealin successfully resolved the block chain "transparent traceability" features and the contradiction between user privacy security, retained the DeFi decentralized core advantages, open and transparent, and build a privacy security barrier for the user, let users enjoy the efficient DeFi service at the same time, no need to worry about the core data leakage and identity exposure and identification. --- # Agent Instructions This documentation is published with GitBook.
