Sunsetting Tor Messenger
I think about trying to hide the metadata of who is communicating...I wonder about a public stream of end-to-end encrypted messages.Anyone can add a message to the stream.Everyone reads all of the messages, and tries to decrypt all of them.There are lots of variants to this, lots of ways to optimize it, probably lots of ways to implement it.  But that's the core idea.One variant is that what everyone downloads is just enough of a message metadata identifier to see if they're the intended recipient (something about Bloom Filters or PGP Signatures or something, I dunno).  Then, if you are the intended recipient, you request the message contents itself.  To obscure which messages were for you, you also download some very large number of other messages.Something about microtransaction fees to pay for all of it.  Maybe something about distributed ledger.  Mumble, mumble.  Maybe messages only live for X days or something.Thoughts?
