You mean something like this https://docs.oasis.dev/general/run-a-node/advanced/copy-state-from-one-node-to-the-other?
oh ok yeah. since we have that written up, let's go ahead and check that first item off the list then
One of the validators, @Bambarello, is already providing such a snapshot.
See https://github.com/Bambarello/cosmos-snapshots and http://snapshots.alexvalidator.com:8081/. Is this what you mean @pro-wh?
Yeah, I think those are the kind of snapshot. Thanks for sharing the links.
The remaining item in this issue is about adding a tool for creating those snapshots.
We now also have Oasis Snapshots (https://snapshots.oasis.io/), an official service providing Oasis Network snapshots.
However, there is no snapshot data for the latest version (oasis-4)
You should be able to sync the latest version from genesis very quickly so no snapshot is needed yet ;)

It is too early for the new network for there to be any snapshots available. Just sync from genesis, it should be quite fast.
I see what this means, the pre-V4 data is almost completely discarded, but the block height does not start at 0. Thank you very much
suppose I have a "serverdir" of a node that's synced. Someone wants to get my copy of that.
goal:
formulate instructions for how to prepare a distributable (i.e. no secret information) bundle of a synced node's state so that recipient can get chain history from a trusted sourcedone
