So we’ve treated some fundamentals, we’ve looked into what are NFTs from a ethnic note perspective, when our NFT is from a sociological position. And then we have even a bit further and look and looked at NFTs from a engineering position, how they work with smart contracts and the brutality. And ultimately, in the last section, we probed into marketplaces. Since we are building an NFT marketplace, it’s important to understand at least the very fundamentals of what constitutes a marketplace. So we should feel pretty good about those fundamentals before is progressing. Assuming that we do, it’s now time to take a look at the NFT r 721 signs. So what is the E. R. C 721 standard? And I want to turn your attention over to once again our crypto kitty-cats because we’re going to use them again. As a comment, we mentioned how in the previous section that CryptoKitties are their own NFTs. They have a marketplace where you can buy and sell, but they’re actually even more special than that.They do more than that. And for those of us who know, we know for those who don’t where we are about to discover. So in 2017, the game CryptoKitties, video games because actually CryptoKitties is a game and it’s a game which demonstrated how non-fungible assets can be made and transactions on the Ethereum blockchain. So how does this game work? Well? Players can breed and sell Kitty-cat. All right. But crucially, crucially, all the Kitten exist on the blockchain and is impossible to be engendered or traded by the player who owns them.So these pussies, they exist on the blockchain, and if you just wanted to multiplied them, if you just wanted to spawned them, then you have to own one. You be given an opportunity to. You have to own one. So let’s compare a traditional online tournament, right, and a traditional online activity. I don’t know if you’re a gamer or not, whether it’s World of Warcraft or it is some kind of casino gamble lotion. All right, these online competitions store data on a central server, and the admins of the games are able to make changes nonetheless they see fit. All right. But in CryptoKitties, in CryptoKitties, actors buy and sell their Kitties on a decentralized and trustless network.All right. So the ownership of their Kittens are irrefutable, are irrefutably, are irrefutably provable. If I own a pussy, it doesn’t matter. It doesn’t matter what you try to do or say. You can be the Guardian. You could be the New York Times, New York Times and saying, Hey, this person doesn’t own a kitty NFT, but the blockchain will say otherwise. It will say otherwise. It doesn’t matter if you are the president of whatever ..
