What is a metadata (in messaging)?
Metadata is the information around a message - who sent it, to whom, when, how often, and from where - as opposed to the message content itself.
End-to-end encryption hides the content of a message, but not its metadata. Knowing that address A messaged address B at 2am, then again after B replied, reveals the relationship and the timing without reading a single word. Intelligence agencies have said plainly that they act on metadata.
A messenger that only encrypts content still leaks metadata through its servers. PrivaMesh treats metadata as a first-class threat and hides it with stealth addresses, cover traffic and a throwaway gas wallet.
