The zkPass Pre-alpha Testnet marks a significant step in the evolution of private data verification for decentralized applications. This initiative introduces a powerful combination of advanced technologies to help users securely manage and verify their personal data without exposing sensitive details.
Introduction to zkPass
zkPass is a privacy-preserving protocol designed for private data verification. It integrates three core technologies: Multi-party Computation (MPC), Zero-knowledge Proof (ZKP), and three-party Transport Layer Security (3P-TLS). These technologies work together to ensure that users can verify their data without revealing unnecessary personal information.
Much of the world’s private data—such as banking records, identification documents, and financial histories—remains locked within centralized systems. This limits the potential for user-centric applications in the decentralized web. zkPass enables secure, selective data verification while preserving user privacy and ownership.
The protocol allows users to generate verification proofs directly from their devices. All without sharing raw data with third parties. This approach supports a wide range of real-world applications—from identity checks to financial compliance—using standard web interfaces.

Core Technologies Behind zkPass
Multi-party Computation (MPC)
MPC allows multiple parties to jointly compute a function over their inputs while keeping those inputs private. In zkPass, MPC helps validate data without any single entity gaining full access to sensitive user information.
Zero-knowledge Proof (ZKP)
ZKP technology enables one party to prove to another that a statement is true, without revealing any information beyond the validity of the statement. zkPass uses ZKP to verify user data without exposing the data itself.
Three-party Transport Layer Security (3P-TLS)
The 3P-TLS protocol is a redesign of traditional TLS, tailored for three-party interactions. It ensures end-to-end confidentiality and authenticity during data retrieval and verification processes.
These technologies form the backbone of zkPass, enabling a trustless, private, and highly secure environment for handling sensitive data across web2 and web3 applications.
Getting Started with the Pre-alpha Testnet
The zkPass Pre-alpha Testnet is now live on Ethereum’s Goerli Testnet, with plans to expand to opBNB Testnet and Scroll Testnet. Early testers can experience core features of the protocol and contribute to its development.
Participants in the testnet can:
- Install the zkPass Transgate browser extension.
- Log into various websites via a PC browser.
- Access private data and generate zero-knowledge proofs locally.
- Mint a series of zkSBT (Zero-Knowledge Soulbound Tokens) representing verified attributes.
These tokens can attest to identity, financial status, education credentials, or real-world asset ownership—all without exposing underlying personal data.
Using Transgate
Transgate is a browser extension that facilitates the transfer of private data from web2 to web3 environments. It incorporates MPC, interactive ZKP, and the 3P-TLS protocol to ensure security and privacy.
Users are advised to only download Transgate from official sources to avoid security risks. Third-party extensions may not undergo the same security vetting and could pose threats to personal accounts.
Available Data in the First Release
The initial phase includes a limited set of trusted data sources. Using the zkPass Protocol, users can generate proofs directly from their devices. Neither the MPC nodes nor the validators ever access or store users’ raw personal data.
Future releases will introduce a zkTemplate toolkit, allowing the community to create custom verification templates for diverse data sources—all while maintaining strict privacy.
Note that as a pre-alpha release, the testnet may exhibit instability. Users should exercise caution and ensure strong account protection during testing.
Roadmap and Future Plans
The Pre-alpha Testnet will run for several months. During this time, the team will focus on:
- Improving MPC network stability.
- Accelerating zk proof generation in browsers.
- Expanding supported web data sources.
- Engaging the community in selecting future data sources.
- Launching an MPC testnet running program.
This iterative development approach helps identify and resolve issues early, ensuring a more robust and scalable final product.
Frequently Asked Questions
What is the main goal of zkPass?
zkPass aims to allow users to verify private data—such as identity or financial records—without revealing the actual data. It uses advanced cryptography to ensure both privacy and authenticity.
How does zkPass protect user data?
By using MPC and ZKP, zkPass allows validation without exposing raw data. All proof generation occurs locally on the user’s device, ensuring end-to-end privacy.
Who can participate in the testnet?
Developers, privacy enthusiasts, and early adopters interested in decentralized identity and data verification can join. Access is granted via official registration.
What kind of data can be verified?
Initial supported data includes legal identity, financial records, educational background, and real-world asset details. More data types will be added based on community feedback.
Is zkPass compatible with existing websites?
Yes. zkPass works with any HTTPS-enabled website, allowing users to generate proofs from standard web portals without special integration.
What are zkSBT tokens?
zkSBTs are non-transferrable tokens that represent verified attributes or credentials. They are minted using zero-knowledge proofs to ensure privacy and authenticity.
