I built it for a digital artist friend who frequently had their art stolen and reposted without credit. Kredence solves this by using a Commit-Reveal scheme combined with Compressed NFTs (cNFTs) to provide verifiable receipts and a dispute system.</p> <h2> Demo </h2> <p><em><a href="https://kredence31.vercel.app/" rel="noopener noreferrer">https://kredence31.vercel.app/</a></em></p> <h2> Code </h2> <p><a href="https://github.com/parthbadgire-code/kredence" rel="noopener noreferrer">Kredence GitHub Repository</a></p> <h2> How I Built It </h2> <p>Kredence is built on the <strong>Solana</strong> blockchain:</p> <ul> <li> <strong>Frontend:</strong> Next.js 15, React 19, TailwindCSS v4, Web3.js</li> <li> <strong>Smart Contract:</strong> Solana, Anchor Framework, Rust</li> <li> <strong>Infrastructure:</strong> Metaplex Bubblegum (cNFTs) for state rent optimization, SPL Account Compression, Token-2022, and Pinata (IPFS) for decentralized storage.</li> <li> <strong>In-Browser Hashing:</strong> A unique SHA-256 fingerprint of the image is generated locally before it hits the chain.</li> </ul> <h2> Why Does Open Innovation Matter? </h2> <p>Open innovation matters because creators need systems they can trust. Centralized platforms can fake timestamps, manipulate data, or simply shut down. By building Kredence as an open-source protocol on a public blockchain, we empower creators to take control of their intellectual property without relying on a walled garden. </p> hf26challenge ai blockchain python
