No Server No Coin Only Blockchain - BlockChat BlockChat uses blockchain technology instead of a central server to provide service to users without requiring any personal data (no sign-up process), while securely protecting the privacy of their messages. We want to reclaim the true nature of communication where only the users involved in a conversation can access the messages and empower all individuals to possess and use their own data. ◆ Your messages, for your eyes only Because the messages transmitted on BlockChat are not channeled through a central server, no one else other than you and the intended recipient can view your messages. ◆ No personal information required By using a Blockchain ID created from your device, BlockChat does not require your personal information to sign-up. ◆ Connect with only who you know You are connected with your friends only by manually sharing the code, which prevents any unintended exposures to people in your contacts. ◆ Protect your messages from being misused BlockChat allows you to edit any message, even those sent by your friends, so taking screenshots becomes pointless. You do not need to worry about your messages being misused. ## Key features - Blockchain-based communication - No personal data required - End-to-end message privacy - Manual friend code sharing - Message editing functionality ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/blockchat/id1635256021/reviews.md ### 5/5 — Great app *2023-07-21* When will a call feature be added?
