NFTs, which are designed to be one-of-a-kind or unique by nature, may become subject to duplication, with data being transformed (cropped, rotated, stretched) or subject to tiny additions that would make a once valuable collector’s item a poor knockoff. The Sense Protocol enables users to measure the relative rareness of an NFT and to certify its authenticity, thus serving to protect creators and collectors from counterfeits, fraud and scammers.
