@InterestingSTEM Pair of headphones = 10
A single men = 5
Pair of watch = 4
Single headphone + a man with pair of headphone and a watch * a watch = 5 + (5 + 10 + 2) * 2 = 39
@_mikepound Hi bro, I need a clarification. In X3DH Double Ratchet encryption, the root key's are oftenly updated/changed right ?! so how the old messages are decrypted if the message key deleted after use! i'm totally confused with that !! (They store the keys in client side??)
