Privacy Protection Demand is Increasingly Urgent

The core competitiveness and inevitable trend of DeFi industry in the era of digital finance. At present, digital finance, especially the rapid expansion of DeFi ecology, user privacy security is facing unprecedented severe challenges to the "transparent traceability" feature of blockchain. While ensuring the openness of transactions, it also puts the core data of users in the risk of "streaking". Unlike traditional financial scenarios, DeFi users each transaction (transfer amount, counterparties, asset balance), every operation (pledge, lending, exchange) will be in the form of "public address + hash" permanent chain, although the address is not directly associated with real identity, but through the chain data analysis (such as address clustering, trading track tracking, associated with centralized exchange charge records), third parties or hackers can still accurately lock user real identity, form an "anonymous but traceable" privacy vulnerabilities. This vulnerability not only infringes on user privacy, but also is likely to cause property security risks.
