Published in April 2023, this guide explains non-fungible tokens (NFTs) and their role in the expanding digital art market. An NFT, or non-fungible token, is a unique digital asset that cannot be copied or replaced by another—unlike a cryptocurrency, which can be exchanged for an identical one. While a physical artwork is singular and non-fungible by nature, NFTs extend this concept to digital files, allowing ownership and authenticity to be verified through blockchain.
High-Value NFT Sales
The market has seen significant transactions. The Merge by artist Pak sold for 91 million dollars on Nifty. Everydays, The First 5000 Days by Beeple reached 69.3 million dollars at Christie’s auction. Clock, created by Pak and Julian Assange as a timer of the WikiLeaks founder’s imprisonment, sold for 52.7 million dollars. Beeple’s Huma One went for 28.985 million dollars. Among CryptoPunks, #5822 sold for 23.7 million dollars, #7523 for 11.75 million dollars, #3100 for 7.67 million dollars, and #7804 for 7.6 million dollars.
How NFTs Are Created
Creating an NFT begins with a digital version of artwork, expressed as binary code (0s and 1s). This sequence is compressed into a unique identifier called a hash—a digital fingerprint that cannot be forged or reversed. The hash is then recorded on a decentralized ledger called the blockchain. Most NFTs are built on the Ethereum blockchain, which requires users to open a digital wallet using apps such as MetaMask, Coinbase Wallet, Binance’s Trust Wallet, or Math Wallet. These wallets store the cryptocurrency needed for transactions.
Trading on Marketplaces
NFTs are bought and sold on virtual marketplaces including OpenSea, Rarible, NiftyGateway, Foundation (used by artists), MakersPlace (invitation-only), and Mintable, which offers an artificial intelligence-powered rarity meter. Buyers place bids in auctions; when an offer is accepted, the platform transfers funds and completes the sale. Some transactions incur a variable gas fee depending on market conditions.
