About CallBox Project

The purpose of the CallBox project is to build truly secure and anonymous communication service.

There're several messengers on the market, which are positioning themselves like secure services with end-to-end encryption. At the same time most of them authenticate us by phone number. It means that even if they haven't access to the content of our conversations they know the fact that person A had a call with person B, after that person C published some important information in mass media.

For example, if you know that person C is the chief editor of certain media, then you recognize that person A which works in the government is his informant. In many cases it's not necessary to know what people say each other, because the fact about an act of communication is already an important information.

Blockchain technology allowed us to build decentralized communication service: miners install CallBox nodes and generate revenue by establishing connections between users. Miners work like commutators. We pay very small fee for each connection. 100% of the fee goes to miner, which connects users to each other. No hidden fees, no payments, just autonomous decentralized messenger company.

For now, we developed beta version of the product. You can try it by exchanging messaging, making calls and sending secrets. When CallBox blockchain node is ready, we will publish all source codes on GitHub. Please support us to make it faster.

Let's build our own messenger today!
