The NFT Billboard Token – An NFT that controls a virtual billboard
 |
Instead of representing ownership of a piece of digital art, the NFT Billboard Token represents ownership of the billboard shown at https://the-nft-billboard.com/. Through smart contract magic, the owner of the NFT — and only the owner — can change the message displayed on the billboard, and those messages are stored on the Ethereum blockchain for as long there continue to be nodes running (so forever, we all hope). If you're curious how this came together, here are links to the contract for the token and the contract for the billboard. Without a publicly exposed "mint" method, there is no way for someone to create more than just the one NFT in the contract, and a simple "require" statement prevents anyone but the NFT holder from posting new messages. Being able to write code on-chain that hooks into NFTs is powerful, and there is so much potential in this ability waiting to be unlocked. We're still in the "tip of the iceberg" territory for this tech. submitted by /u/TheNFTBillboard |
