Bmail will be the protected mail service working at base of technology a blockchain. The idea is: the mail service will be the network decentralized by autonomous P2P with own cryptoeconomy which is not needed to be controled from outside. Advantages of technologies of the distributed data storage allow us to create the platform for integration of third-party applications, steady against blocking, protected from censorship and collecting personal data. It means, for example, that you will not need to worry about possible loss of correspondence because Google will decide to close Gmail, and if something happens you will be able to replace the postal address because completely you will control it with ease. But the mail service is not only mail, on this base we plan to develop the big multipurpose platform. There will be a photo and video hostings, communication and entertaining services.
