• Re-visit delTree(). Suggestion is deleting small trees on the memory later, otherwise only deleting the root vertex (so it becomes inaccessible) and remember the follow up vertices which can travel through the tx-layers to be picked up by the backend store.

• Some comletions migh be needed for the aristo_part module which is a re-implementation of the module supporting proof-mode/partial trees.

  • Complete partMergeStorageData(). This function might not be needed at all unless snap-sync is really revived.
  • For snap-sync, write a proof function verifying whether the partial tree is correct relative to the PartStateRef descriptor.
  • One might need to re-visit the removeCompletedNodes() module when using snap-sync proof features. The algorithm used here assumes that the list of proof nodes is rather small. Also, a right boundary leaf node is typically cleared. This needs to be re-checked when writing the proof function mentioned above.

• aristo_nearby also qualifies for a re-write, now
