Protocol for Private Data based on MPC, ZKP, 3P-TLS.
Verify your real-world private data without revealing your private details.

Lero Network serves as a seamless gateway between the private data of the Web2 and Web3 ecosystem.
Three Pillars of Privacy
TLS
Lero Network integrates decentralized MPC Nodes into a 3-party Handshake process, improving the standard TLS protocol. It allows users to log in securely and generate ZKPs locally without API access or data source authorization.
MPC
Randomly selected task nodes supervise the 3-party handshake, obtaining a portion of the mac_key to ensure data integrity and authenticity, prevent scams and tampering, and maintain user privacy. The enc_key only remains with the user, so the nodes cannot access or gather user data.
ZKP
Users generate a Zero-Knowledge Proof (ZKP) locally using the response from a TLS-based data source. They can then upload this ZKP on-chain as a unique soul-bound token or share it solely with a specified address, providing enhanced privacy options.
Developer Tools
LeroGate
LeroGate is a foundational product that incorporates three key technologies: MPC network, Interactive Zero-knowledge proof system, and 3P-TLS protocol. The LeroGate enables the seamless transfer of private data from the web2 realm to web2 or web3.
Install ExtensionLeroGate SDK
The included client-sdk and server-sdk, both low-code integrations, enable businesses to trust the zero-knowledge proofs generated by individual or enterprise users from trusted data sources without compromising privacy.
View DocumentationSchema Builder
Schema is a mapping of specific HTML elements to the certificate generation system. Through schema, users can select target data sources and personalized fields according to business needs, and seamlessly integrate them into the Lero protocol.
Coming Soonimport { LeroGate } from '@lero/sdk';
const lero = new LeroGate({
network: 'mainnet',
schema: 'identity/kyc-verification'
});
// Generate proof from any HTTPS data source
const proof = await lero.prove({
dataSource: 'https://bank.example.com',

}
});
// Verify on-chain or off-chain
const result = await lero.verify(proof);Core Capabilities
Privacy-Preserving
Users can prove everything without uploading any documents via Lero Network.
Compatibility
Seamless compatible with all HTTPS-based web sessions without APIs.
Verifiability
Verify the provenance, authenticity, integrity and validity of private data.
Anti-Cheating
Protects against malicious activities such as identity theft and data tampering.
Memory-Efficiency
Hybrid ZK proof system that enables millisecond ZKP generation in a browser environment.
The Most Efficient
and Affordable
Zero-Knowledge
We have developed and optimized the memory-efficient Hybrid ZK proof system including VOLE-ZK and zk-SNARKs algorithm, which allows users to generate zero knowledge in less than 1 second in the browser environment of a PC, process tens of millions of gates per second, and handle large circuits with billions of gates while requiring less than 300M of memory.
