zkPass

• zkPass Protocol: A decentralized open source protocol consisting of Transport Layer Security, Multi-Party Computation, Zero Knowledge Proof, and other technologies. It is run by zkPass Node to build a decentralized Verifier that participates in the three-party TLS protocol.
• zkPass Kit: Build a Prover for the three-party TLS protocol on top of the TCP layer alongside the HTTP layer in the form of a plugin/SDK. Business users select or customize a suitable KYC template according to their needs, configure the template into zkPass Kit in the form of parameters, and initiate KYC requests to the smart contract on the blockchain.
• Smart Contract: 1)Template: Store templates and related parameters to prevent Verifier from cheating.2)Task: Assign tasks to specify MPC participants to prevent Verifier from conspiring.3)ZK Verification: verify ZKP to prevent user privacy leakage.

• Compatibility: zkPass Protocol is backward compatible and widely adapted to the current data source protocol, while the data source does not know the data destination.
• Decentralization: The zkPass Protocol is completely decentralized as there is no centralized service to store sensitive user data.

zkPass is a decentralized KYC solution based on MPC (Multi-Party Computation) and ZKP (Zero-Knowledge Proof), which aims to overcome the various flaws in the current KYC system, eliminate the pain points related to identity authentication, and protect user privacy while expanding KYC capabilities.

• Generality: Individual users can generate and reuse their identity multiple times, and their information will not leak to any third party throughout the multi-party interaction.
• Customization: Enterprise users can select and configure KYC templates on demand to meet KYC needs in different dimensions, while the verifying party knows nothing about the data.
• Privacy-preserving: Strong data privacy-preserving is achieved through MPC (interaction session) and ZKP (proof session), while the parties to the agreement do not know the data.
