Can we raise the max clock drift allowed? Seems unsafe to make the max clock drift under a block time, and you can get block times of 10s with 1-2 round increments |
I think that we can raise it to 7s...... maybe? This is a judgement call which may require prayer / meditation. Seems like one could, but also seems like this could make IBC overall more risky. When looking into shared security stuff, I've been imagining a faster parent chain, slower child chain. These errors, overall, could be taken as declaring "lower block time gonna do better". Maybe. Except when ibcing with a slower chain to whom you may seem to be in the future. Time is harsh, code-wise. Only way to test this might be to build some interconnected network of chains-- and then grow it.... 🤔 |
Per that ibc-rs issue, my reading is that increasing this time moderately has ~no risks / downsides. Its mostly about tolerating clock drift on smaller scales. (Or at least thats my reading, I am admittedly horribly under-informed here) |
I feel the same. I suppose that we could try it for the next release. |
Whats the sitaution like now? I think we're going to be more able to get this resolved via pinned announcements on the discord/telegram. We can coordinate if you'd like to make a discord announcement |
This is still happening, but less often, and may have been related to fee calculation in hermes..... but the same thing would happen with the Go relayer, too. I'm going to close this, and shoot out a missive in discord + survey, to see if validators are using ntp or systemd-timesyncd or similar. Maybe this was improved in ibc-go 2.0? |
Hi,
I'm operating a relayer. If you are operating a validator, it is very important that you:
please.
If you do not, there are time drift errors, and well, the Hermes default of five seconds is really pretty generous. We should be less than five seconds apart.
