Real Estate NFT

This project was developed as part of the Udacity Blockchain Developer Nanodegree Program

This project lets you mint NFTs to represent your title to properties. Before you can mint a NFTs, you need to verify you own the property. It uses zk-SNARKs using ZoKrates to create a verification system which can prove you have title to the property without revealing that specific information on the property. Minted tokens can be transferred to other addresses.
