Sorry for my ignorance, but may I know how the encrypted messages and the "ShadowChat" will be technically realized? If the contents of these communications will be stored in the blockchain for all eternity, then I could certainly see how people would be hesitant to adopt these features, considering that the encryption could somehow be broken in the not-too-distant future. On the other hand, if these communications are p2p only (i.e. between the two parties directly), then SDC would not be needed for them, right? Or am I mistaken?
