CredentialHub

Inspiration

Hiring runs on trust, yet résumés are easy to fake and slow to verify. Universities waste time confirming degrees, and employers deal with fraud and long verification cycles. We wanted a solution where credentials are instantly trustworthy and fully owned by the user.

What it does

CredentialHub turns any résumé into blockchain-verified credentials: Users connect a wallet → get a decentralized identity Upload a résumé → parsed into structured credentials Universities approve items by signing them Solana stores credential hashes + institutional attestations Employers verify credentials instantly through a public check portal Everything is cryptographically verifiable, tamper-proof, and user-owned.

How we built it

Frontend: Next.js, Tailwind, Backend: Node.js, PostgreSQL/Supabase, Blockchain: Solana + Anchor storing credential commitments and attestations Verification Portal: Re-hashes credentials to confirm on-chain authenticity

Challenges we ran into

Designing a privacy-preserving yet verifiable credential model Making university signing simple but secure and incentivized to use Reliable résumé parsing under time pressure Coordinating off-chain data with on-chain hash commitments

Accomplishments that we're proud of

Clean university and employer portals Implementation of Solana smart contracts Smooth wallet-based identity onboarding Strong UX

What we learned

How to combine off-chain data with on-chain proofs Best practices for Solana + Anchor smart contract design UX design principles for decentralized identity systems
