If it is correct that only the hashes of PowPing messages/transactions are saved onchain, when they get tipped, so, maybe we should download any messages that we think are valuable enough for us to keep stored for an eventual proof necessity?
If for any reason, powping gets hacked and data lost, having the offline transactions backed up can be good.
Maybe this is not a priority for now, but as things grow it could be nice to have a download button on transaction page, or maybe a download full account messages feature.
