System that ensures secure identity verification for Farcaster users participating in decentralized networks, enabling authentic identity to be recognized. The goal is to help build a trusted, Sybil-resistant environment for the community.

• Sybil attacks caused over $900M in losses. 💸
• Threats to identity and humanity erode trust, necessitating security overhauls in decentralized systems. 🆔
• From Coinbase to Proof of Humanity, unified interoperable standards are crucial. 🔗

• Farcaster Frame that let Farcaster users easily use Ethereum Attestation Service on Arbitrum One to attest to their accounts. 🎫
• Gitcoin Passport is the first use case using the attestation as a primitive for Sybil resistance. 🛡️

• On-Chain Verifications: Use @eas_eth for secure verifications. 🏷️
• Community Trust: Incorporate @farcaster_xyz primitive to @gitcoinpassport. 🛂
• User-Centric Design: Use Farcaster Frames for usability and interactiveness to encourage adoption. 🖼️
• Interoperability and Efficiency: Use @arbitrum for smooth, cost-effective and secure integration. ⚡

• Full decentralization: Eliminate backend dependencies by enabling direct network interactions for attestation creation and dispatch. This will help achieve a fully decentralized solution, building on the groundwork laid during the hackathon.

• attestation-server: Attest Farcaster accounts using Ethereum's Attestation Service on Arbitrum One.
• attestation-frame: Facilitate Farcaster account attestation using Frames.
• gitcoin-passport: Gitcoin Passport allows users to prove their identity through a secure, decentralized UI.

• USER: Farcaster mobile or web user.
• FARCASTER HUB: Farcaster is a sufficiently decentralized social network. Farcaster Hubs are a distributed network of servers that store and validate Farcaster data.
• FARCASTER FRAME: Farcaster Frames is used to turn any cast into an interactive app. Within this project, it allows users to verify their account directly on the app.
• WARPCAST: Warpcast is a decentralized social media platform built on Farcaster.
• GITCOIN PASSPORT: Gitcoin Passport deployed on DigitalOcean with the Farcaster Stamp added. In order to verify an account, it checks the Ethereum Attestation Service GraphQL instance on Arbitrum One.
• ARBITRUM ONE: Arbitrum One most dominant L2 on Ethereum by Volume and TVL used to store and query the EAS attestations through their smart contracts.
• EAS: Ethereum Attestation Service is an infrastructure public good for making attestations onchain or offchain about anything.
• NEYNAR: Neynar provides services to build on Farcaster. Used to validate requests on Frames.
• VERCEL: Vercel hosting provider for the BE and FE.
