The problem Geo-Locked NFTs solves

Gives much more geographical control over minting of an organisation's NFT to their users without compromising their privacy in any way. With FHE we don't need to decrypt the encrypted data to work on them, so user's data once encrypted doesn't need to decrypted on-chain thus preventing any sensitive data leaks.

Challenges we ran into

Learning new tech such as FHE was a difficult but a fun task, alas we made it through the difficult phase.
