What are Digital Collectibles or NFTs?

Authentic digital assets on the blockchain explained

Like a physical collectible, a digital collectible is 100% authentic, distinguished and unique. To ensure each digital collectible’s unique authenticity, BookCoin™ uses blockchain technology to demonstrate and prove rights, ownership and authenticity — officially making it a Non-Fungible Token or NFT.

This is similar to receiving a "certificate of authenticity" with unique physical merchandise like a signed baseball card or autographed book.
