CryptoKitties

CryptoKitties are digital collectibles built on blockchain technology, representing unique virtual cats with distinct appearances and traits. Each Cat is an NFT (non-fungible token), meaning it’s one-of-a-kind and owned securely online. Users can buy, sell, breed, or trade these digital cats, with their ownership verified on the blockchain. Launched in 2017, CryptoKitties popularized the concept of blockchain-based collectibles, combining gaming with digital asset ownership. They exemplify how blockchain can create, manage, and trade unique digital items that are transparent, scarce, and verifiable.
