In the Web3 data ecosystem, there is a "trust pitfall": individual users want to authorize on-chain data to earn $C, but fear that "transaction records and NFT collections will be misused"; small and medium-sized DeFi projects worry about "non-compliant data sources and regulatory risks"; offline bookstores want to check customer NFT information but fear "collecting too much privacy and being questioned by customers"—"no privacy protection and compliance risks" make many participants hesitant to take the first step even if they want to use data. As a decentralized data infrastructure, Chainbase is building a "Privacy Protection Shield" with "data de-identification + compliance certification", allowing personal data to only reveal "the parts that should be revealed", ensuring small projects use data in compliance with regulations, and completely eliminating concerns about "privacy leakage".
Its core capability is to achieve both "data usage" and "privacy protection", rather than forcing users to choose between "earning profits" and "protecting privacy". On the technical level, Chainbase has created a "Privacy Compliance Hub": for individual users, the hub has launched "dynamic de-identification technology"—when users authorize data, the system automatically hides sensitive information (such as masking 10 characters in the middle of wallet addresses and displaying transaction amounts only as "small/medium/large"), only allowing access to "necessary data" (such as "whether holding a certain type of NFT" or "whether there have been DeFi transactions in the past three months"), and generates a "privacy authorization certificate" so users can see "who used the data and what parts were used" at any time. Xiaohan, a white-collar worker in Beijing, previously refused to authorize due to fear of privacy leakage, but now relies on de-identification technology to earn 300 $C monthly from authorized data, saying, "I know sensitive information is hidden, and I feel particularly at ease using it"; for small and medium-sized projects, the hub has developed a "compliant data pool"—all data has undergone "source certification" (confirming user voluntary authorization) and "compliance review" (meeting regulatory requirements such as EU GDPR and Singapore MAS), and projects will receive a "compliance report" upon procurement to avoid penalties for non-compliant data. A 4-person DeFi project, which previously hesitated to procure data due to compliance concerns, is now optimizing risk control with user data from the compliant data pool, not only eliminating risks but also reducing bad debt rates by 25%; for offline merchants, the hub has designed a "privacy-friendly query tool"—merchants can only see "whether customers meet discount conditions" (such as "yes/no holding brand NFT"), without seeing the complete wallet address or other on-chain assets, and query records are real-time synced to customers, clearly showing them "how the data is used". After using it, a community bookstore in Shanghai saw customer acceptance of data queries rise from 30% to 80%, and no complaints regarding privacy have been received since.
When the ecosystem is implemented, Chainbase doesn't just use "privacy slogans" but focuses on hard-core protection for scenarios where "leakage is feared". For individual users, it launched a "Privacy Management Center"—users can independently set the "degree of de-identification" (such as "completely hide transaction amounts" or "only show transaction months"), and can withdraw "authorized but unused data" with one click, and view the "data usage log" (such as "a project used your NFT holding data on March 15 for membership discount evaluation"), currently having 3.15 million users activating the management center, increasing trust in data authorization by 95%; for small and medium-sized projects, it launched the "Compliance Escort Plan"—providing projects with "data compliance training" (teaching "how to legally use data and how to respond to regulatory inspections"), and offering "compliance insurance" (if facing compliance penalties for using Chainbase data, the maximum compensation is 100,000 $C), a 5-person GameFi project successfully passed local regulatory review through this plan and obtained compliance operating qualifications; for offline merchants, it initiated the "Privacy Transparency Initiative"—providing merchants with "privacy notification scripts" (such as "we only check if you have the store's NFT, and won't look at other information"), and posting "data usage instructions" in stores to make it clear to customers. Recently, it helped a coffee shop in Hangzhou with an event, and through transparent operations, inquiries related to privacy decreased by 70%, while participation rates increased by 50%. Even more user-friendly, Chainbase has also developed a "Privacy Risk Detection Tool" where users can input "the type of data they want to authorize" to display "which information will be de-identified and what privacy risks might exist", allowing users and projects to have a clear understanding of privacy protection.
In the long run, its value lies in "rebuilding the 'trust foundation' of Web3 data with 'privacy protection'", making "using data with confidence" the norm. Currently, Chainbase has 3.15 million individual users and 145,000 small and medium-sized cooperative projects/merchants using data through the protection shield, among which 90% of users state that "they authorize long-term due to privacy guarantees", and 85% of projects believe that "compliant data makes business safer". Recently, the project has also reached cooperation with the global privacy certification body ISO/IEC, and its privacy protection technology has been certified by the ISO/IEC 29100 privacy framework, further enhancing international compliance recognition, and it is expected to add 2.15 million individual users; cooperating with the Web3 privacy protocol zkSync to integrate zero-knowledge proof technology into data de-identification, making privacy protection more thorough while not reducing data usage efficiency. The "privacy attributes" of the C token are also being strengthened: users using privacy management features can enjoy a 10% bonus on C earnings; projects purchasing compliant data can enjoy a 30% discount when paying with C; users/projects staking C will have priority access to advanced privacy protection features (such as "zero-knowledge proof de-identification"), a design that keeps the $C staking rate stable at 99%, with daily trading volume increasing by 140%.
From helping white-collar workers confidently authorize data to earn profits, to allowing small projects to use data compliant to reduce risks, and then to enabling bookstores to transparently check NFTs to gain trust, Chainbase is providing Web3 data participants with a sense of "security" through its "Privacy Protection Shield". As more scenarios are covered by privacy protection and the technology becomes more robust, this "secure" data platform may establish a new bottom line for the Web3 data ecosystem where "privacy is guaranteed, and compliance is risk-free", encouraging more people to participate with confidence and invest in the data ecosystem for the long term.
