I think the Bmail project is not focusing on privacy as much as safety . Yes you can't be hacked on the blockchain but on the other hand your transactions won't be private. If you guys read the white paper there's no mention of the sender / receiver privacy. read "Various blockchains allow to distribute data on different chains that in combination with various types of enciphering allows to create the most flexible and protected communication network. We took
the best from this that there is for realization of bmail on the basis of technology a blockchain today. "
Nice dude, since you already read the whole page on the white paper much better we will ask to those staff or dev who can answer about it's privacy as well as on its security. Privacy and security should be the most important to gain trust on this project .
