What are NFTs and how do they work?


NFT is the terminology that stands for Non-Fungible Token which is a non-interchangeable data unit on blockchain. It is an Ethereum-based asset to represent anything unique and create more power for the content creators than ever before. The smart contracts on the Ethereum blockchain are to power the NFTs. Basically, NFTs are the tokens that represents the ownership of unique items and tokenize the things such as art, collectibles, real estate, etc. They are secured by Ethereum blockchain and have officially one owner at a time.

NFTs and Ethereum jointly solve many of the internet problems today. As everything is becoming digital, there need to replicate the properties of physical items such as uniqueness, proof of ownership, and scarcity. No two NFTs are the same but digitally unique and every NFT must have an owner that is a public record for anyone to verify. The content creators can sell their work anywhere and access the global market. They can also retain ownership rights over their own work, and claim resale royalties directly.

NFTs are powered by smart contracts to handle the transfer and verification of the ownership. The NFT standards such as ERC-721 provide the functionalities for smart contracts.

NFTs are the way to represent anything unique by the help of smart contracts on the Ethereum blockchain. However, the minting done with the help of smart contract assigns NFT ownership and manage its transferability. On the creation and minting of NFT, the stored code is executed in smart contracts that conform to different standards such as ERC-721. This information becomes the part of the blockchain where NFTs could be managed.
