Summary
NFT standards like EIP 721 and EIP 1152 have a critical flaw: they don't require a cryptographic hash (a unique digital fingerprint) linking the actual content to the blockchain entry, so the blockchain only proves you own a token ID, not the actual digital asset it claims to represent. This means metadata files and images can be stored centrally (for example, on Amazon S3), modified by anyone with access, or disappear entirely, leaving you unable to prove ownership of the original content even if you have a local copy.
