(ETH) NFT is not even on the blockchain, it is just a URL pointing to a JPEG website
BTC NFT (including Ordinals, Atomicals) converts small images (files) into code and stores them permanently on the BTC blockchain
This is different from traditional NFTs that use centralized servers or IPFS and other technologies to store images. BTC NFT is a pure full-chain NFT
brc20's ARKB and ETCS are worth a look. OK wallet can buy and sell
