What Are NFTs and How Do They Work?

Transactions on the Ethereum blockchain are incredibly energy inefficient; one transaction uses more power than the average US household does in a day, according to the Institute of Electrical and Electronics Engineers. For years, Ethereum developers have planned to move the blockchain to a different operating model, called proof of stake, which will be less energy-intensive. Still, energy inefficiency — and the novelty factor driving up the price of NFTs — is worrisome to some artists and cryptocurrency critics.

Each card was initially sold for approximately $1 and now provides Shatner with passive royalty income every time one is resold. Ethereum token standards ERC-721 and ERC-1155 are the main blueprints created by Ethereum that allow developers to create and deploy their own non-fungible tokens on top of its blockchain.
