MustaFair: The Trust Layer for Web3
What is MustaFair?
MustaFair is a decentralized identity and reputation protocol that unifies Web2 and Web3 identities into a single, verifiable on-chain profile. It allows users to establish credibility and trust by anchoring real contributions—both off-chain and on-chain—to a permanent, sybil-resistant identity using CARV ID and soulbound NFTs.
How It Works
The journey begins when a user mints a CARV ID, a unique identity NFT that connects their Web3 wallets with Web2 accounts like GitHub and Google. This creates a cross-platform digital fingerprint that cannot be duplicated. Once minted, the user can also mint a Reputation NFT, which is soulbound—meaning it cannot be transferred, sold, or gamed. This reputation evolves over time, reflecting real activity and engagement from the user across decentralized ecosystems.
Reputation-Driven Governance
MustaFair introduces a tiered governance system, where only verified CARV ID holders can participate in decision-making processes. Users can vote on reputation upgrade proposals, with voting power based on their on-chain activity and trust level. This ensures that influence is earned—not bought or farmed—and makes governance more meaningful, community-led, and secure against bots or spam accounts.
Post-Voting and Trust-Based Interactions
By restricting interactions like voting, commenting, and content curation to verified CARV ID holders, MustaFair ensures all engagements are sybil-resistant. Every upvote, downvote, or decision is tied to a real, provable identity, fostering a trust-based environment where bots and fake accounts can't thrive. This system is ideal for DAOs, forums, and social platforms that require real accountability.
Developer Experience
MustaFair comes with a modular, open-source SDK (@mustafair/reputation-sdk) and a suite of RESTful APIs. Developers can easily authenticate users through their wallets, fetch CARV ID and reputation data, gate features based on trust levels, and build community leaderboards. Whether you're creating a governance app, an access-controlled DAO tool, or a reputation-aware social dApp, MustaFair is lightweight and flexible enough to plug right into your stack.
Real Adoption and Ecosystem Impact
With over 250 active SDK users on NPM and real usage across live Web3 governance platforms, MustaFair has moved beyond the hackathon stage. It’s already enabling meaningful identity and trust flows in production environments. The frontend has seen dozens of CARV IDs and Reputation NFTs minted, and more integrations are in the pipeline.
Why MustaFair Matters
MustaFair isn’t just a cool experiment—it’s a foundational identity layer for the decentralized internet. In a world where bots and fake identities dilute real engagement, MustaFair ties reputation to real humans. It helps DAOs, dApps, and developers build trust-first ecosystems that are transparent, authentic, and resistant to manipulation.

해커톤 진행 상황
Day 1: Ideation and Architecture We began by finalizing the core concept of MustaFair—merging decentralized reputation scoring with a sybil-resistant, community-driven post board. The team sketched out the initial UI layout and drafted the architecture, mapping out how Web2 and Web3 identities would flow into a unified system. Day 2: Identity Integration and Backend Setup On the second day, we focused on establishing on-chain user verification through CARV ID integration. Alongside that, we began developing a custom SDK wrapper to simplify backend interactions and laid the foundation for the backend API structure that would later support reputation scoring and voting logic. Day 3: SDK Development and API Expansion The third day was all about execution. We finalized the SDK and published it on NPM, enabling functions like minting CARV IDs, submitting posts, casting votes, and tracking reputation. To ensure flexibility, we also built RESTful API endpoints for teams preferring HTTP-based workflows over the SDK. Day 4: Frontend Integration and Real-Time Features Frontend work took center stage on Day 4. Using React and Tailwind, we implemented the full UI/UX flow—integrating post submission, wallet connection, and real-time syncing of reputation scores. The influence of each user was visually reflected on the platform as their reputation evolved. Day 5: Final Touches and Launch Readiness The final day was focused on polish. We completed detailed documentation for both the SDK and platform, added a Whisper-powered transcription tool to generate voice-guided demo scripts, and successfully onboarded over 250 developers to the NPM package. The platform was now fully functional, live, and ready for adoption. By the end of the hackathon, MustaFair had grown from a concept into a fully operational, modular, and extensible reputation protocol—live on-chain, developer-ready, and open for contributions from the community.
