| Titre | A quick FAQ about NFTs |
| Texte | I thought I'd write up 4 technical questions about NFTs. They may not be the ones you ask, but they are the ones you should be asking. The questions:What does the token look like?How does it contain the artwork? (or, where is the artwork contained?)How are tokens traded? (How do they get paid? How do they get from one account to another?)What does the link from token to artwork mean? Does it give copyrights?I'm going to use 4 sample tokens that have been sold for outrageous prices as examples.#1 What does the token look like?An NFT token has a unique number, analogous to:your social security number (SSN#)your credit card numberthe VIN# on your carthe serial number on a dollar billetc.This unique number is composed of two things:the contract number, identifying the contract that manages the tokenthe unique token identifier within that contractHere are some example tokens, listing the contract number (the long string) and token ID (short number), as well as a link to a story on how much it sold for recently.0x2a46f2ffd99e19a89476e2f62270e0a35bbf0756 - #40913 (Beeple $69m)0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB #7804 ($7.6m CryptoPunks)0x9fc4e38da3a5f7d4950e396732ae10c3f0a54886 - #1 (AP $180k)0x06012c8cf97BEaD5deAe237070F9587f8E7A266d - #896775 ($170k CryptoKitty)With these two numbers, you can go find the token on the blockchain, and read the code to determine what the token contains, how it's traded, its current owner, and so on.#2 How do NFTs contain artwork? or, where is artwork contained?Tokens can't*** contain artwork -- art is too big to fit on the blockchain. That Beeple piece is 300-megabytes in size. Therefore, tokens point to artwork that is located somewhere else than the blockchain.*** (footnote) This isn't actually true. It's just that it's very expensive to put artwork on the blockchain. That Beeple artwork would cost about $5million to put onto the blockchain. Yes, this less than a tenth the purchase price of $69million, but when you account for all the artwork for which people have created NFTs, the total exceeds the prices for all NFTs.So if artwork isn't on the blockchain, where is it located? and how do the NFTs link to it?Our four examples of NFT mentioned above show four different answers to this question. Some are smart, others are stupid -- and by "stupid" I mean "tantamount to fraud".The correct way to link a token with a piece of digital art is through a hash, which can be used with th |
