Systems and Methods for dispersed data structures (DDS) in a distributed storage network are disclosed. A dispersed storage processing unit handling a request to insert a key value pair into a DDS could lookup what the most up to date DDS is, which could be held by a single source with a pointer to the current DDS root. The processing unit could then descend the DDS until it finds the leaf node that owns the requester's key and make a copy of the leaf with the key inserted. The processing unit could then make a copy of the parent of the node, replacing the pointer to the copied node with a pointer to the new copy, repeat this step until the root is reached, and make a copy of the root in a similar fashion but also including a pointer to the original DDS root.
