+Add the `PostKey` and `PostCountKey` to the `x/blog/types/keys.go` file:
+
+```go title="x/blog/types/keys.go"
+	// PostKey is used to uniquely identify posts within the system.
+	// It will be used as the beginning of the key for each post, followed bei their unique ID
+	PostKey = "Post/value/"
+
+    // This key will be used to keep track of the ID of the latest post added to the store.
+    PostCountKey = "Post/count/"
 ```
