NFTs, or non-fungible tokens, are unique digital assets that use blockchain technology to prove ownership and authenticity. Unlike cryptocurrencies, which are fungible and have interchangeable value, NFTs are one-of-a-kind and cannot be replaced or exchanged for something of equal value. NFTs can represent a variety of things, such as digital art, collectibles, music, or even virtual real estate. The ownership and provenance of an NFT is recorded on the blockchain, providing a tamper-proof and permanent record of the asset's ownership history. This allows for the buying, selling, and trading of NFTs as valuable and unique assets in their own right, with prices for some NFTs reaching into the millions of dollars. NFTs have gained popularity in recent years as a way for creators to monetize their digital creations and for collectors to invest in unique, one-of-a-kind assets.
