What is zkPass (ZKP)?

The separation between the traditional internet (Web2) and the blockchain environment (Web3) is still one of the main barriers to broad adoption. Web2 platforms store vast amounts of valuable user information, including financial records, social profiles, and legal documents. At the same time, most Web3 applications cannot work with this data unless they depend on centralized intermediaries or require users to compromise their privacy.

zkPass was created to address this data gap. It relies on cryptographic methods that allow users to bring real-world data and reputation onto the blockchain without handing sensitive information to third parties. Below is an explanation of how this system operates and why it is relevant.

What is zkPass?

zkPass is a decentralized protocol focused on private data verification. It acts as an infrastructure layer that allows users to prove information from Web2 sources — such as banks, online platforms, or public institutions — to Web3 smart contracts in a controlled way.

Its main purpose is to verify facts without exposing the underlying data. For instance, a user can show a DeFi protocol that their credit score exceeds 700 without revealing the exact number, their identity, or any credit history details.

How zkPass Works?

The design of zkPass relies on two established cryptographic approaches: Multi-Party Computation (MPC) and Zero-Knowledge Proofs (ZKP). One of its more notable features is the way it adapts the standard internet security protocol TLS (Transport Layer Security).

1. Three-Party TLS (3P-TLS)

Normally, when you access a bank website over HTTPS, a two-party TLS connection is formed between you (the client) and the bank (the server). This encrypts the data so only you can read it.

zkPass extends this model to a three-party setup that includes:

• The Prover (the user accessing the data)
• The Verifier (a zkPass node that observes the exchange)
• The Web Server (the original data source, such as Google, Amazon, or a bank)

In this arrangement, the Verifier joins the TLS handshake to confirm that the data truly comes from the correct server. Due to the cryptographic design, the Verifier never sees the decrypted content. It only receives cryptographic evidence that the exchange took place as claimed.

2. TransGate

TransGate is the interface that allows users to interact with this system. Through TransGate, a user can create zero-knowledge proofs from any HTTPS website. After activation, the user selects specific data points from a webpage, converts them into a cryptographic proof, and submits that proof on-chain for decentralized applications to verify.

3. Zero-Knowledge Proof Creation

After the data is accessed and confirmed through 3P-TLS, it is transformed into a zero-knowledge proof. This method allows one party to confirm a statement is true without revealing the information behind it. As a result, sensitive personal data never leaves the user’s device in a readable form.

Possible Applications

zkPass supports many scenarios by connecting off-chain information with on-chain use.

• DeFi and under-collateralized lending: DeFi lending often demands excess collateral because protocols lack insight into a user’s financial reliability. zkPass can be used to prove off-chain financial conditions, such as account balances or credit scores, allowing better loan terms without exposing identity.
• Identity verification (DID): Users can confirm facts like age, citizenship, or compliance with KYC rules without uploading identity documents to multiple platforms, lowering the risk of data leaks and fraud.
• Gaming and social platforms: Players can verify ownership of assets or achievements from Web2 gaming platforms to gain access to rewards or features in Web3 systems.
• Creator economy: Content creators can prove that they control accounts with large followings, enabling access to private DAOs or business agreements without revealing account details publicly.

Advantages of zkPass

• Privacy protection: Users keep control over their data and share only cryptographic proofs instead of raw information.
• No API dependency: zkPass works with any standard HTTPS site and does not require special API access from Web2 companies.
• Broad compatibility: The proofs generated by zkPass can be used across multiple blockchains, supporting cross-chain applications.
• Fraud resistance: Since data is verified directly from the source server through TLS, attempts to fake credentials using screenshots or modified web pages are prevented.

What is the ZKP Token?

The ZKP token powers the zkPass network and is used to pay for services that convert private data into verifiable proofs.

ZKP is issued as an ERC-20 token with a fixed maximum supply of one billion units. It also incorporates LayerZero technology to enable secure and efficient use across different blockchains.

The token serves four main functions:

• Users and applications spend ZKP to generate proofs and verify information.
• Network node operators must lock ZKP as collateral, which can be forfeited in case of misconduct.
• Developers and organizations use ZKP to access zkPass tools and features.
• Token holders can participate in voting on protocol changes.

The ZKP token is listed on many platforms, including Bitrue, Upbit, Bithumb and Binance.US. If you’re looking to list your token on similar platforms, understanding the token listing process and crypto exchange listing fees is essential.

Conclusion

Interest in linking real-world identity and reputation with blockchain systems continues to grow, but this should not require sacrificing privacy. zkPass presents a practical answer by combining standard HTTPS security with MPC and zero-knowledge techniques. This approach allows data verification that is safer, more private, and better suited for large-scale use.
