- heretoo 16y agoExactly. I was trying to think how to build a chat program on this, and establish keys between two chatees for communicating, but it seems impossible to make a public channel/key for registering interest in chatting in the first place, without using an untrusted readwrite channel/key. An append only store might solve it, with a key that is globally known. Some sort of broadcast channel. An append only, with limited size appends, and cleared at regular intervals.
- markchristian 16y agoGood challenge! Here's a start: Say you and I want to chat with each other. We both pick a random key to store our messages in. Let's call those key[markchristian] and key[heretoo]. Each of those has a read-only version -- readonly[markchristian] and readonly[heretoo]. I'll post the key readonly[markchristian] to "markchristian-to-heretoo". You post the key readonly[heretoo] to "heretoo-to-markchristian". Our chat clients can just poll those keys, looking for new messages -- whatever hand-wavy format we want to have. Problems: 1. Requires us to agree to chat ahead of time and know each other's usernames. 2. Nothing to stop a malicious third-party from putting a different readonly key at the "heretoo-to-markchristian" pointer keys.
