+- Completed a comprehensive analysis of nine candidate variants of Leios, examining three basic variants and three sharding strategies:

-  - Sharding strategies: Unsharded, Sharded, Overcollateralized 1x
+  - Sharding strategies: unsharded, sharded, overcollateralized 1x
 - Identified significant differences in spatial and temporal efficiencies across variants:
-  - Full with transaction references achieved highest spatial efficiency (95.999-96.466%)
-  - Full without IBs demonstrated fastest time to ledger (43.052-43.057s)

   - Sharded variants generally showed improved spatial efficiency but increased latency
