The CKB Ecological Fund is pleased to announce a strategic investment in SilentBerry, a decentralized publishing platform built on the innovative RGB++ protocol. SilentBerry, based on the RGB++ protocol, allows authors to engrave their book content on Bitcoin and creates four types of digital assets - gold berries, silver berries, copper berries, and blueberries - representing ownership and revenue rights of the books. Users can purchase digital assets using BTC, ETH, and CKB to obtain printing rights for the books and enjoy royalties from the books.
