Until recently, digital files were seen as something infinitely copyable and identical. An image shared online could have thousands of copies, each looking exactly like the original. Music, video, or digital art could be stored on countless devices, and no one could prove who owned the “real” version. The internet had no scarcity, and therefore no true sense of ownership. Everything changed with the emergence of NFTs, which transformed digital objects into fully unique assets with defined ownership, history, and value.
