 ## Reserved Namespaces
 
 Celestia reserves certain namespaces with specific meanings.
+Celestia makes use of the reserved namespaces to properly organize and order transactions and blobs inside the [data square](./data_square_layout.md).
 Applications SHOULD refrain from using these reserved namespaces for their blob data. <!-- the implication of this is still under investigation, but it is prudent to advise app developers not using this namespace -->
-The rationale behind this is that these namespaces dictate the positioning of transactions and blobs data within the Celestia [data square](./data_square_layout.md).
-Therefore, by refraining from using these reserved namespaces, applications can guarantee the desired arrangement of their blob data.
 
 Below is a list of reserved namespaces, along with a brief description of each.
 In the table, you will notice that the `PARITY_SHARE_NAMESPACE` and `TAIL_PADDING_NAMESPACE` utilize the namespace version `255`, which differs from the supported user-specified versions.
