The token proves that your copy of a digital file is the original, like owning an original painting. When you pay for an NFT, what you get is the right to transfer the token to your digital wallet. The first NFTs were made using the cryptographic technology underlying the Ethereum cryptocurrency. Ethereum blockchain is the basis for most of the currently offered NFTs because it supports the ERC-721 token standard, enabling NFT creators to capture information of relevance to their digital artifacts and store it as tokens on the blockchain. This design makes it very difficult to alter transaction data stored in blockchain.Īlthough blockchain was initially devised to support fungible assets like Bitcoin and other cryptocurrencies, it has evolved to enable users to create a special kind of crypto asset, one that is nonfungible, meaning provably unique. To be a party in blockchain-based transactions, each user needs to create a pair of keys: a public key and a private key. This allows for fast retrieval of past records. The transaction records of a chain of blocks are stored in a data structure called a Merkle tree. Each block is locked by a cryptographic hash, or string of characters that uniquely identifies a set of data, to the previous block. It uses cryptography to chain blocks into a growing list of records. Two crypto keys play the role of digital signatures and are commonly used in blockchain to enable both authentication and anonymity for transactions.īlockchain is a crucial technology for creating NFTs. The special mathematical properties of these two crypto keys are widely used to provide secrecy and integrity. You then use your private key to put it back into its original form. This message manipulation is enabled by a pair of keys, public and private keys: You share your public key with your friend, who uses it to transform his message to you into an unintelligible sequence of random characters. Everyone else will see it as only an unintelligible sequence of random characters. Keys and blocksĬryptography is the technique used to protect privacy of a message by transforming it into a form that can be understood only by the intended recipients. The process is the same for cryptocurrencies, which turn strings of bits into virtual coins that have real-world value. Turning something as ephemeral as a tweet into an item that can be sold requires two things: making it unique and proving ownership. Its value is determined by what someone else is willing to pay for it and nothing else. The truth is that the value of any NFT is speculative. NFT marketplaces do not always accurately describe the value proposition of the goods they are selling. The issue is that perceptions of what the buyer is paying for are not easily framed in legal terms. My friend’s questions were an attempt to understand where the underlying value of an NFT comes from. Similarly, it was hard to miss the news about the iconic GIF Nyan Cat being sold as a piece of art, Twitter’s founder transforming the first tweet into an NFT and putting it up for sale, or an NFT of a New York Times column earning half a million dollars for charity. The bidding started at $100, and the rest of the auctioning process transformed it into a historical event. Mike Winkelmann, an artist known as Beeple, created this piece of digital art, made an NFT of it and offered it for sale. What prompted his interest was the sale of a collage composed of 5,000 digital pieces, auctioned by Christie’s on March 11, 2021, for a remarkable US$69 million. An NFT is worth what someone is willing to pay for it, which can be a lot if the NFT is made by a famous artist and the buyer is a wealthy collector.Īn attorney friend recently asked me out of the blue about nonfungible tokens, or NFTs.Unlike crypto coins, which are identical and worth the same, NFTs are unique.Nonfungible tokens prove ownership of a digital item – image, sound file or text – in the same way that people own crypto coins.
