+
+Data **retrievability** is the ability of nodes to retrieve historical information from the
+blockchain. Historical data is not needed to verify new blocks; it is only required for synching
+full nodes from the Genesis block or serving specific historical requests.
+
+Data **availability** assures full nodes can access and verify the full transactions associated with
+a specific block. It does not necessarily imply that the data is accessible forever. For more
