I’m ready to move EduTrace from concept to a working MVP on the Kaspa blockchain and need a builder who can make that happen. The focus for this first milestone is a simple, web-based verification portal where anyone can drop in a credential hash and instantly confirm its authenticity on-chain. Core scope • Build Kaspa-powered anchoring logic that writes credential proofs (UTXOs) using SilverScript covenants. • Support issuance and verification for educational diplomas, transcripts, and certificates right from day one. • Design both institution and student workflows: schools must be able to issue and revoke, while graduates should download or share proofs for employers. • Expose a clean front-end that shows status, timestamp, and tamper-proof evidence in seconds. Acceptance criteria • One-click issuance writes a verifiable Kaspa transaction; hash, timestamp, and metadata are queryable. • Verification portal returns a validated / invalid / revoked state under three seconds. • All three document types process end-to-end without manual intervention. • Codebase and covenant scripts are handed over with clear README and setup instructions so I can redeploy independently. If you already speak Kaspa and have experimented with SilverScript covenants, you’ll feel right at home. If you’re just eager to dive in and can prove past UTXO-based projects, that works too. After the MVP goes live, I plan to extend EduTrace into physical asset tokenization, so there’s plenty of room to grow the engagement. Let’s get this portal live.
