ySign

With our ySign app, we can send messages and make phone calls to others free, secure and anonymous! Creating and developing an app for communication without stored information was our goal. Instead of storing your chat communications or calls on a central server, ySign uses blockchain technology for decentralized file sharing to carry and distribute encrypted messages. The decentralized blockchain is our way to secure and guarantee users total privacy during the exchange of information. If there is no centralized copy of all data, there is also no possibility to misuse any information about users. Also, the application doesn't require any personal information from users - users are registered just with username and password.
