I will assume by now you folks know what an NFT (Non-Fungible Token) is. It is basically a representation of ownership of various objects. It can be an image, a sound, a video, that can be demonstrably linked back to you, as a rightful owner of the object.
Cryptokitties
Cryptokitties was one of the first NFTs being developed on the Ethereum platform. Back then, it was so popular it regularly clogged the entire blockchain. At one point in time, it felt like nothing else was being done on the blockchain, except for people buying, selling and mating their kitties.
Of course, I got swept up in that fervour, and got myself not 1, not 2, but 8 of those cats....
