 ## Genesis Configuration
-
-@alpe we should document all the genesis config for x/wasm even more.
+We strongly suggest **to limit the max block gas in the genesis** and not use the default value (`-1` for infinite).
+```json
+  "consensus_params": {
+    "block": {
+      "max_gas": "SET_YOUR_MAX_VALUE",  
+```
 
 Tip: if you want to lock this down to a permisisoned network, the following script can edit the genesis file
 to only allow permissioned use of code upload or instantiating. (Make sure you set `app.ProposalsEnabled=true`
