Non-fungible tokens (NFTs) seem to be everywhere these days. From art and music to tacos and toilet paper, these digital assets are selling like 17th-century exotic Dutch tulips—some for millions of dollars.

But are NFTs worth the money—or the hype? Some experts say they’re a bubble poised to pop, like the dot-com craze or Beanie Babies. Others believe NFTs are here to stay, and that they will change investing forever.

Non-fungible tokens (NFTs) are cryptographic assets on a blockchain with unique identification codes and metadata that distinguish them from each other.

Unlike cryptocurrencies, they cannot be traded or exchanged at equivalency. This differs from fungible tokens like cryptocurrencies, which are identical to each other and, therefore, can serve as a medium for commercial transactions.

NFTs evolved from the ERC-721 standard. Developed by some of the same people responsible for the ERC-20 smart contract, ERC-721 defines the minimum interface—ownership details, security, and metadata—required for the exchange and distribution of gaming tokens. The ERC-1155 standard takes the concept further by reducing the transaction and storage costs required for NFTs and batching multiple types of non-fungible tokens into a single contract

The NFT market grew dramatically from 2020–2021: the trading of NFTs in 2021 increased to more than $17 billion, up by 21,000% over 2020's total of $82 million. NFTs have been used as speculative investments, and they have drawn increasing criticism for the energy cost and carbon footprint associated with validating blockchain transactions as well as their frequent use in art scams.The NFT market has also been compared to an economic bubble or a Ponzi scheme. By May 2022, the NFT market was seen as beginning to collapse.
