user2068: I am aware that offchain metadata is stored using the registration as Cardano Developers portal dictates, my concern is about on-chain metadata.
Is really any NFT-metadata stored on-chain? Like blockfrost says?   Since  NFT are just pairs of police id and name... Where is onchain metadata stored ?  As far as i understand metadata can only be attached to a TX ... So the metadata should be attached to the mint- TX Wich can be always traced and is stored in blockchain,  is this right ?
Or i am getting confused at comparing two different kind of native assets ?

user1919: Yes there is NFT metadata stored on-chain and yes they are stored initially on the mint tx although you can update it later (basically overriding it in a new tx). If the NFT metadata follow the CIP25 you'll see it "properly" rendered on several sites such as pool.pm.
