+    // So for example keep track of tx hash
+    //
+    // We also need to loop through all newly added items to the validator node
+    // and repeat the same for our local merkle tree. The order of added items
+    // to local merkle trees must be the same.
+    //
+    // One way to do this would be that .apply() keeps an in-memory per block
+    // list of the order txs were applied. So then we can repeat the same order
+    // for our local wallet trees.
+    //
+    //   [ tx1, tx2, ... ]
+    //
+    // So the wallets know these are the new txs and this was the order they
+    // were applied to the state in.
+    // State updates are atomic so this will always be linear.
