NFTs and web3, deep dive

A grounded, skeptical-but-fair look at NFTs and the broader 'web3' ecosystem: what ownership on a blockchain actually means, why NFT prices boomed and then crashed hard, real uses beyond speculation, and where the genuine technology ends and the hype begins.

What an NFT actually is

An NFT, or non-fungible token, is a unique entry recorded on a blockchain that represents verifiable ownership of a specific digital, or digitally-linked, item. 'Non-fungible' just means not interchangeable: one peso coin is identical to any other peso coin, so pesos are fungible, but an NFT is deliberately made to be one-of-a-kind or part of a limited, individually-numbered set, so token #47 is not the same as token #48.
