We created a new protocol, the Ketab protocol, and then our own ereader to display it. It's allows each chapter, and sections of a chapter, to be their own short form post on Nostr and people can engage and zap it. My book is the first we're testing inside the NextBlock app. In the future, others will be able to publish their works. And use NextBlock of course to promote it. I'm sorry to say it's not ready for your manuscript but please follow along with us. We're working towards this capability.
