fix-AppHash

Roll back:

(20241031)

Hello again Validators!

We have now identified the issue causing the AppHash errors during the last few days! The issue was caused by bad combination of mempool configurations that are not compatible with EVMOS. This then caused some validators to have different AppHashes for blocks.

We have made a new release v0.5.3 that forces the NoOp mempool configuration for the node.

These are the steps to fix your node:

• Stop your node

• Update to binary v0.5.3

• Do a

wardend rollback --hard

• Start your node
