    There isn’t a way to verify if there isn’t another copy of an NFT on the blockchain.

    Incorrect. An NFT is tied to a particular token number at a particular address.

    The URI the NFT points to may not be unique but NFT is unique.

      The NFT is only unique within the contract address. The whole contract can be trivially copied to another contract address and the whole collection can be cloned. It’s why opensea has checkmarks for “verified” collections. There are a unofficial BoredApe collections which are copies of the original one.

          Completely agree, but the guy I responding to thinks the monkey jpeg is unique across the whole blockchain, when that isn’t true. The monkey jpeg can be copied. There’s no uniqueness enforced in a blockchain.
