• Optimize select_inputs_from_accounts to return a single change operation instead of a vector
• Write cache layer on top of the storage layer, specially if accounts are settled
• Improve read performance with SQLite
• Add a locking mechanism, to either a start a tx per account, or use the storage engine as a lock mechanism (to lock the utxos)
• Add ability to query accounts in a point in time
• Write other servers, other than the restful server
• Add caching layer: This cache layer can built on top of the utxo::ledger, because all operations can be safely cached until a new transaction referencing their account is issued, by that point, all the caches related to anaccount can be evicted
• Build admin interface
• Add memo to changes. Build append only table with all movements as inserts. Wraps the objects to all their changes
