SpaceDataBank

A project for buying and selling satellite data on Web3. Users can encrypt and upload satellite data using Lighthouse. After uploading, mint the hash value received from Lighthouse and the metadata of satellite data. Minted NFTs can be bought and sold on the marketplace. NFT buyers can use Lighthouse's Share feature to download and unzip the uploaded data.

This project uses Lighthouse and fevm on hyperspace testnet.

By using Lighthouse, I was able to upload large files in an encrypted state. And by minting the hash value and the metadata necessary to search for satellite data as an NFT, we are able to buy and sell satellite data on the NFT marketplace.

In addition, once the NFT is purchased, the contract cannot be relisted, so that only the satellite data provider can sell the satellite data (however, it was not implemented).
