The environments supported by BCM are Android 5 (Lollipop) and above as well as iOS 9 and above. If your smartphone platform is any of those mentioned above and is connected to the network through the carrier's mobile network (such as 3G, 4G) or WIFI, then you can download and use BCM.
Q: How is BCM different from SMS?
SMS is a traditional way of communication with limited functionalities. Each message generates a fee, and the message is visible to the telecom service provider. BCM is completely free, and you don't have to worry about the disclosure or leakage of any private information in a very secure chat environment. Additionally, you can use the diverse functionalities such as "supergroup" and "virtual currency wallet".
Q: How is BCM different from Telegram?
Technically, BCM is similar to Telegram in some aspects: both of them use 256-bit AES symmetric encryption algorithm for content encryption, and the encryption level is extremely high.
The differences between BCM and Telegram are:
1) Every message in BCM private chat and group chat is end-to-end encrypted, the forwarding node cannot get access to its content
2) Telegram's encryption of group chat and default private chat both happen on the App & both ends of the server which means the server can get access to the decrypted content. End-to-end encryption is used for private-chat only after the "Secret Chat" mode is turned on.
Q: How is BCM different from WhatsApp?
From technical perspectives, the private chat of BCM and WhatsApp are both based on Signal Protocol, and the security of the encryption algorithms of both Apps are the same.
However, while group chat of both BCM and WhatsApp are end-to-end encrypted and support Perfect Forward Security (PFS), the number of people in WhatsApp's group chat can't exceed 256/per group when every group of BCM can support up to 100,000 people.
In addition, WhatsApp does not open source, but BCM will gradually open source.
