- Reduce the size of new storage units issued. Lets us bring down the cost of registration in the future.

We're looking for feedback on this, either in this thread or on Github. 

We'll be discussing this at the next protocol meeting on Aug 15 before we make a final decision. 

This change should be net positive for users and developers.

Is there a maximum limit to the storage I can have?
