Decreasing HTTP Outcall Latency and Cost

I think step 7 is where I don’t see how we could make it work. Every replica talks to other replicas of the subnet to agree on the input, and then independently executes the messages. Replicas on their own can’t know whether other replicas have different state, so we would need to introduce new communication here to figure out if they actually agreed or not, and if not, how we pinpoint the cause for disagreement within thousands of processed messages & 100s of GBs of state.

So there is no agreement on the output? Once the inputs are agreed upon, you’re saying that the canisters just execute? So…where is the consensus on the outputs? What if a canister decides not to execute the same as the other canisters? I thought there was detection for the most minimal deviation from deterministic execution?

I might just have to go read the papers more in-depth.
