    > First, keep in mind that there's no metadata that tells the receiver 
whether a block is encrypted or not. This means that methods like 
BlockManager.get, which can read block data from either local or remote 
sources, need to return data that is either always encrypted or always not 
encrypted for the same block ID.
    
    This can be solved by tagging the block data with a prefix byte - we do 
something similar for MapStatus (direct or broadcast).
