Damus, referred to as the "Twitter killer", which runs on a decentralized network, has received approval on the Apple App Store. The Damus team announced the approval to their 11,500 Twitter followers on January 31, after facing what they claim were three rejections from Apple. Twitter co-founder and Nostr contributor Jack Dorsey then shared the news with his 6.5 million followers and called it a significant moment for open-source protocols.
