The capstone will build upon the knowledge you have gained in the course in order to build a decentralized housing product. This project creates ERC721 tokens for real estate titles and uses ZkSNARKs to verify before minting the token. The minted tokens are then put to sale on opensea.
Truffle v4.1.14 (core: 4.1.14) Solidity v0.4.24 (solc-js) Ganache CLI v6.2.5 (ganache-core: 2.3.3)

To run truffle tests:
In a second terminal window run the following commands
truffle test ./test/TestSquareVerifier.js
truffle test ./test/TestSolnSquareVerifier.js
truffle test ./test/TestERC721Mintable.js
To deploy to rinkeby:
Update the truggle-config.js file to reflect your infura settings for rinkeby
In a terminal window run :
truffle migrate --network rinkeby
