There is a project that has been quite popular recently—zkPass ($ZKP, ZKPUSDT trading pair), but its logic is quite different from typical DeFi or public chain projects. Strictly speaking, it is a combined solution of a privacy data protocol and verification layer infrastructure.

Starting from the core issue. In the Web2 world, there is a fundamental dilemma: how to reliably bring real data onto the chain? If you want to prove your age, identity, account status, financial records, or health data, traditional methods only allow authorized APIs, access to third-party servers, or direct upload of complete information. The result? Privacy leaks or the constant risk of tampering.

zkPass’s approach is to use a combination of cryptographic techniques such as zero-knowledge proofs, Multi-Party Computation (MPC), and zk-TLS. The core idea is quite ingenious: you can generate verification proofs locally and use these proofs to demonstrate the authenticity of certain data on-chain, while the raw content remains completely undisclosed.

From a different perspective, understanding the significance of this mechanism—verification is indeed genuine and effective, yet the privacy data is fully transparent to the outside world. Verification can be generated for any data source supporting HTTPS, and the entire process does not rely on centralized validators. This turns private data into verifiable on-chain proofs, with the data itself always protected.

In terms of technical positioning, zkPass is not just a simple application like an identity chain. It is more like building a privacy-first infrastructure layer, aiming to bridge the gap between Web2 data and Web3 verification needs. This approach has potential application spaces in privacy computing, identity verification, financial compliance, and various other ecological directions.
