Welcome to the NFT metadata persistence problem.

Art NFTs and Collectible NFTs usually follow the same data pattern: the NFT points to a metadata file, which points to an image file.

The problem is that if the metadata and image file are hosted on a third-party server, and that server disappears, then the NFT points to nothing, and its perceived value will drop.

If the metadata and image file are on the IPFS, persistence is also not guaranteed. There still has to be someone out there with a copy of the files on their IPFS server.

In this epsode I talk about a simple insurance policy for data persistence, to make sure your NFT metadata and image can be found.

(This all assumes that the blockchain will last, but that's a different issue)
