Background of zkPass

In the Web2 environment, centralized platforms control vast amounts of high-value data, including transaction records, account information, and social data. While this data is authentic and reliable, users face significant challenges leveraging it in Web3 scenarios without exposing their privacy. zkPass was developed to address this issue, enabling users to “prove ownership of certain data” instead of “submitting the complete data itself.”
Core Technical Principles of zkPass
zkPass is not a single technology, but a composite cryptographic protocol built on three core components: TLS, MPC, and Zero Knowledge Proof.
TLS underpins today’s HTTPS communications. zkPass enhances this with three-party TLS (3P-TLS), which ensures that data truly originates from the designated website. MPC (Multi-Party Computation) prevents any single party from tampering with the data. Zero Knowledge Proof enables assertions about the data’s content without revealing the underlying information.
How zkPass Delivers “Verifiable but Not Visible”
Within the zkPass framework, users act as Provers, retrieving information directly from the data source and generating a Zero Knowledge Proof. Verifiers simply validate the proof’s correctness without accessing any actual content. This approach fundamentally shifts the traditional model of “platforms reading user data,” restoring privacy control to the user.
Typical Use Cases for zkPass
zkPass has broad applications in areas such as identity verification, credit scoring, KYC compliance, and airdrop eligibility verification. For instance, users can prove that “an account balance exceeds a certain threshold” or “specific historical behaviors are met” without disclosing any account details.
The Role of zkPass in the Web3 Ecosystem
zkPass serves as a trusted bridge for data flow between Web2 and Web3. It not only strengthens privacy protection, but also lowers the barriers for Web3 applications to access authentic data, expanding real-world access points for decentralized applications.
