Book.io is the next chapter in the story of books - a multi-chain, Web3 marketplace for buying, reading, and selling eBooks and Audiobooks. These are not public NFT images of book covers – they are fully Decentralized Encrypted Assets (DEAs). They are the entire book, fully decentralized and living on-chain forever. Readers can now buy and truly own their eBooks and Audiobooks and sell them on secondary marketplaces.
