Design idea for instant replies

estebanabaroa commented 1 year ago

Motivation: instant replies are important for sites like 4chan. The IPNS updates can only occur every X minutes. Also useful for reddit live threads.

Design idea for instant replies

a pubsub topic named "<subplebbitAddress><postCid>"

peers that want instant replies join the pubsub. whenever a peer receives the challenge verification for their reply, they publish the publication from the challenge verification to the pubsub (publication will now need to contain a comment update signature from sub owner)

whenever a peer receives a message in the pubsub, he validates the message with subplebbitAddress signature and postCid

whenever a peer joins the pubsub, he receives all messages posted in the last 10 minutes (older than 10 minutes are available in the comment update so not needed)

design idea for instant posts in a subplebbit

a pubsub topic named "<subplebbitAddress>timestamp600" (timestamp newer than 600 seconds)

same exact same strategy as replies, execpt what is being validated is timestamp instead of postCid

downsides

posting replies is not as anonymous, your IP can more easily be linked to your reply
not scalable to do using a pubsub provider, needs to be P2P, to support the web/mobile user we'd need to use a webrtc pubsub implementation, which needs some kind of centralized signaling server (maybe not, I think IPFS is implementing how to do webrtc without centralized signaling), can use more than one signaling server and they usually dont censor cause all p2p messages are e2e encrypted
since pubsub provider can't be used, and webrtc needed, not possible to do over tor, so not as anonymous

Since we changed the plebbit.publishInterval, subplebbit updates are pretty fast. If I edit a subplebbit in CLI I can see the new ipns with the change propagated in the daemon in about 10s. So there may not be a need for this idea imo. We should wait and see

that's true should wait and see, it'll probably only be needed when subs have tens of thousands of users. I guess it's low priority for now
