An unknown party of two makes eavesdropping difficult. It's like listening to someone talking over the phone. One party is loud and clear. The other is silent. Blindtalk is a crypto-messaging platform where senders post signed messages here and expect the receivers to search for them. The senders sign the messages using their cryptocurrency addresses. And the receivers verify them like-wise. While the senders are anonymous, the receivers are totally unknown to the platform. Blindtalk has no proof that the receivers had received the messages.
