An explanation of how NFTs work on Ethereum and what NFT provenance is all about. A briefly review how provenance works for CryptoPunks, BAYC, Autoglyphs, the Beeple NFT, and CyptoKitties.
Note: I misspoke a bit, the Beeple NFT provenance is not really *the worst* example — I would say CryptoKitties has among the worst provenance.
