NFTs are increasingly being recognized for their utility beyond speculative trading, with significant applications in digital ownership, art royalties, and gaming assets. By leveraging blockchain technology, NFTs provide verifiable ownership and authenticity, allowing creators to earn royalties and gamers to trade in-game items. Additionally, NFTs are being explored for embedding usage rights into digital media and applications in event tickets and real estate deeds. Despite challenges such as high gas fees and regulatory uncertainty, the development of layer-2 scaling solutions and eco-friendly blockchains is underway to address these issues. This evolution marks a shift in the perception of NFTs from mere collectibles to valuable tools in various industries.
