What is an NFT, how does it work, and what is it actually used for?

NFT stands for Non-Fungible Token. It represents ownership of a unique digital asset on the blockchain. “Non-fungible” means each NFT is one-of-a-kind - 1 Bitcoin equals every other Bitcoin (fungible), but 1 NFT is not equal to any other NFT.
When an NFT is created (“minted”), a unique identity and ownership record is written to the blockchain. Whoever holds that NFT has visible and verifiable ownership on-chain. When ownership changes, the record updates.
Owning an NFT means you own that specific digital asset - it could be a digital image, music, video, in-game item, trading card, or any digital object. However, one important note: buying an NFT doesn’t mean you own the copyright to the content. You typically own only that specific token.
