What is the underlying mechanism of NFTs?

I’m trying to gain a deeper understanding of how NFTs really function. In particular, I’m curious whether new digital tokens are systematically introduced on a regular basis—perhaps even annually—or if one must purchase tokens that already exist within the market. As a newcomer to the world of NFTs, I find myself a bit puzzled by the various ways these digital assets are created and exchanged. A clear explanation of whether NFTs are frequently generated or simply traded among collectors would help clarify my confusion.

hey everyone, i’ve been diggin into this topic as well and it feels like nfts are really an interesting fusion of tech and art. from what i’ve seen, each nft is basically a unique digital record stored on a blockchain, which means it has a verifiable signature that can’t just be altered at whim. sometimes new tokens are minted by creators on demand and other times people buy them off existing collections, so it’s not like there’s a scheduled drop every year or something. it’s kinda wild how creation and trading both play a role in the lifecycle of these tokens. has anyone explored how the minting process affects the overall value or even the environmental impact, especially with all these new eco-friendly chain alternatives popping up? would love to hear more perspectives on what makes the value of an nft more than just its digital signature.
