Sunsetting Tor Messenger
I think about trying to hide the metadata of who is communicating...<p>I wonder about a public stream of end-to-end encrypted messages.<p>Anyone can add a message to the stream.<p>Everyone reads all of the messages, and tries to decrypt all of them.<p>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.<p>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.<p>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.<p>Thoughts?
