How do you think there will be no problems with the messenger government agencies. After all, it turns out that all the information will be anonymous and not available even for the developers themselves. All conversations will be stored in the blockchain. Not alerted whether some states such excessive anonymity?
It seems that the developers have settled this issue and there should be no problems with the law. But for some reason it seems to me that some countries will not allow its use.
How these countries will be able to block this messenger? Website blocking? Or your what?
