Humanized

Humanized: Cross-Chain Identity Verification System Humanized is an advanced cross-chain identity verification platform built to solve challenges related to identity fraud and Sybil attacks in decentralized ecosystems. Its primary function is to consolidate multiple blockchain addresses under a single, verifiable human-centered identity, enabling fair and transparent participation in blockchain activities such as airdrops and decentralized governance.

By introducing DNS-like domain names, Humanized allows users to create a unified identity across multiple blockchains, including Ethereum, Solana, Flow, Dase, and others. This identity is verified through various task-based methods, such as CAPTCHA-solving and other user-driven tasks, which are used to differentiate between real users and bots. Advanced cryptographic techniques ensure that each verified identity is authentic, thus safeguarding decentralized systems from fraudulent actors.

Humanized also integrates off-chain data, such as ride-sharing services, online purchases, and payment systems, to strengthen identity verification. This ensures that human verification encompasses not only digital behavior but real-world activity, all while preserving privacy.

The platform's Sign Protocol is crucial to the user verification process, where users prove their humanity through specific schema-based challenges. The Reclaim Protocol introduces off-chain data verification for services like Uber and Amazon, making the decentralized identity more robust. Additionally, Lit Protocol uses advanced cryptography, including Multi-Party Computation (MPC), to protect users' sensitive data and ensure that only authorized parties can access encrypted information.

Humanized is designed for Web3 but serves as a bridge between Web2 and Web3 ecosystems, enabling smoother interactions and secure identity verification across traditional and decentralized platforms. By consolidating identities across multiple blockchains, Humanized simplifies cross-chain operations and ensures that digital assets, tokens, and NFTs are managed securely and fairly.

Humanized's vision is to revolutionize Web3 with a robust, decentralized, and human-centered identity verification system that enhances security, fosters trust, and improves user experience across the entire decentralized ecosystem.

Humanized is built with a sophisticated stack of Web3, blockchain, and machine learning technologies, ensuring secure, seamless cross-chain identity verification. Here's a more detailed look at the tools and technologies used and how they benefit the project:

Technologies Used: Frontend (Web):

Next.js: Benefit: Provides server-side rendering, which improves loading speed and SEO, ensuring a smooth and fast user experience, crucial for a system handling large-scale user verification.

Tailwind CSS: Benefit: Enables rapid UI development through utility classes, ensuring a highly responsive, consistent, and polished design across devices.

Radix UI: Benefit: Delivers accessible, high-quality UI components, ensuring compliance with web accessibility standards and a more user-friendly interface.

Three.js: Benefit: Powers 3D biometric user verification, allowing the future integration of 3D visuals and animations for security purposes (e.g., facial recognition).

Framer Motion: Benefit: Provides smooth, interactive animations, enhancing the UX and giving the application a modern, dynamic feel.

Chart.js: Benefit: Visualizes data (like blockchain interactions, verification progress) in an intuitive way, helping users and administrators track important information.

Backend & Blockchain:

Solidity: Benefit: The backbone of smart contract development. Solidity enables us to implement decentralized protocols such as Sign, Reclaim, and CCIP Protocols securely and efficiently.

Chainlink & Oracles: Benefit: Oracles allow the project to securely fetch off-chain data, such as Uber rides or Amazon orders, to verify real-world activities. Chainlink provides trusted, tamper-proof data feeds crucial for decentralized applications.

Thirdweb: Benefit: Simplifies interactions with smart contracts and blockchain development by offering pre-built solutions for NFT minting, token distribution, and contract deployment, making Web3 integrations more seamless.

Ethers.js: Benefit: Ethers.js makes it easier to interact with Ethereum-based contracts and wallets, handling transaction signing, network switching, and wallet integrations.

MongoDB: Benefit: A NoSQL database used for scalable data storage, allowing us to store user metadata, verification progress, and task records efficiently. MongoDB's flexibility helps us store dynamic user attributes.

Machine Learning (ML) Integration:

FastAPI: Benefit: A fast, asynchronous API framework that facilitates communication between the frontend and ML algorithms for tasks like facial recognition and data processing.

Pandas & NumPy: Benefit: Essential for data handling in the ML pipeline, enabling smooth processing of large data sets related to user tasks, verification histories, and biometric scans.

Face Recognition: Benefit: Enhances the security of human verification tasks by allowing for facial authentication, adding an extra layer of protection against bots and Sybil attacks.

Core Protocols and How They’re Pieced Together:

Sign Protocol: Benefit: Verifies users through task-based challenges (e.g., solving CAPTCHAs). This helps prevent bots and automated accounts from participating in airdrops or decentralized governance, ensuring only legitimate users can interact.

Reclaim Protocol: Benefit: Links off-chain data with blockchain identity, verifying users' real-world actions without compromising privacy. This enhances the authenticity of decentralized identities by factoring in off-chain activities.

Lit Protocol (MPC): Benefit: Uses Multi-Party Computation (MPC) to manage secure key-sharing and data encryption, ensuring no single party holds complete control over data decryption. This is vital for cross-chain interactions and encrypted API calls.

CCIP Protocol: Benefit: Ties all blockchain addresses under a single, customizable domain name, simplifying cross-chain interactions and preventing airdrop manipulation. It also allows seamless integration across multiple blockchain platforms, including Ethereum, Solana, and Flow.

Partner Technologies and Benefits:

Chainlink Oracles: Benefit: Securely connects off-chain data to blockchain identities, validating real-world actions like Uber rides or Amazon purchases. This expands the reach of decentralized verification by linking Web2 activities with Web3 identities.

Thirdweb: Benefit: Provides pre-built templates and tools to integrate Web3 features like NFTs and token distribution, reducing development time and ensuring reliable smart contract interactions across the platform.

Notable Hacks and Implementation:

Cross-Chain Task Execution: Hack: Implemented a system that allows tasks to be completed and verified across multiple blockchains. This was essential in preventing Sybil attacks and ensuring users could only participate once across different chains.

Dynamic Whitelisting via Off-Chain Data: Hack: By using off-chain data such as Uber rides and Amazon orders, we can dynamically adjust whitelisting. This innovative approach ensures only genuine users can participate in the human verification and airdrop processes.

Overall, the project benefits from a tight integration of blockchain, machine learning, and encryption technologies, ensuring a secure, user-centric, and scalable cross-chain identity system.
