Real Estate Marketplace

About

From Udacity:

In this project, you will represent your ownership of the property using ZK-SNARKs and then mint tokens to represent your claim to the property. You will then make these tokens available for sale on blockchain marketplace.

Real Estate Marketplace is a decentralized application that allows users to create tokens that represent real estate. These tokens are verified using ZK-SNARKs and can be sold on OpenSea.
