# Uni-5 v12 alpha app hash

jacob/reece call 1/22/2023

Jacob believes that the issue is entirely gas related. The reason is that The chain is not actually stopping and the block has the same contents. So if we look at different nodes, we get exactly the same upcoming block. however we still get the block.header.apphash error.  nodes don't crash because the state is the same but the gas is different. So instead they just reject the proposal.

The proposal contains numerous transactions. nodes are rejecting the proposal because they each calculate gas for their own and that is different.  So they are finding that the gas in the proposal block does not match what their node finds.

followup:

* roll back to pre upgrade
* run the upgrade again with the [fixed upgrade handler](https://github.com/CosmosContracts/juno/pull/525) (good catch!)

If doesn't work:

* remove x/globalfees
* roll back again to pre upgrade
* upgrade again without globalfees

if that doesnt work:

* remove globalfees and feeshare
* roll back again to pre upgrade
* upgrade again without globalfees

sus transactions:

* mike.exe store code
* multiple choice voting

We sure to run the suspicious transactions again. most likely whatever is causing the problem is in one of these suspicious transactions.


**longer term**
this is a good case for IBC test. If we are unable to make IBC test work so that we can simulate upgrades in CI, I'd like to recommend that we talk to Osmosis and copy exactly what they're doing. I talked to them about it recently.
