According to CoinDesk, two years ago, non-fungible tokens (NFTs) attracted global attention with their soaring prices and mainstream attention, but then the market fell back and many people declared NFTs "dead". However, this technology continues to proliferate around the world and reshape the entire industry. Although the sales of NFT markets have approached 200,000 NFTs per day, worth more than $191 million, it is easy to regard them as toys of Internet culture because projects like CryptoPunks and Bored Apes have attracted a lot of attention. The NFT industry has invested a lot of energy and resources to achieve this goal, building, testing and releasing some of the most transformative technologies to date. Although some NFT markets have now fallen by more than 90%, it would be a mistake to give up on NFTs too early. NFTs are a how, not a what. What does it take to trade assets in a digital environment? Ownership. NFTs are just our way of recording who owns the rights to an asset. They can prove ownership and authenticity and have many blockchain features such as interoperability, secure transfer and verification. The NFT industry creates a revolutionary system of property rights that is available to anyone 24/7/365, costs a fraction of traditional systems, and can make any asset, including digital files, unique. What is bought, sold, or transferred is the rights to the underlying asset linked to the NFT. The assets and rights that can be transferred are virtually unlimited. NFT is a global ownership system that is changing what is possible and reshaping existing industries.
