BLOCKCHAIN DEV NEEDED — NFT Minting + Transfer Simulation on XRP Ledger Testnet

Posted last week

Worldwide

Summary

1. A Python script that reads a spectral .csv file (Raman data from a gemstone) and generates a unique digital fingerprint (SHA3-256 hash)—this is what makes the token tamper-proof. 2. A simple web interface (a single page) to upload the file, display the hash, and mint the NFT on the XRP testnet. 3. Simulate a transaction: transfer the NFT from Wallet A (Seller) to Wallet B (Buyer)—both transactions are visible on the XRPL testnet explorer.
