According to Foresight News, the CKB Eco Fund has strategically invested in Silentberry, a decentralized publishing platform. Silentberry is built on the RGB++ protocol, allowing authors to inscribe their book content on the Bitcoin blockchain. The platform transforms book ownership and royalty rights into four types of digital assets: Goldberry, Silverberry, Copperberry, and Blueberry. Users can purchase these digital assets using BTC, ETH, and CKB to obtain printing rights and earn royalties from the books.

The first book to be published on Silentberry is 'Saving Democracy' by renowned professor Qin Hui, scheduled for release on January 3, 2025.
