Yeah. The response to the issue of the LLM cheating should be removing the LLM's access to the ledger. If the architecture allowed the LLM access to the ledger, I have zero reason to believe any amount of cryptography will prevent it. Talk about bloat. The general idea seems salvageable though.
Sibling comment from OP reads very much as LLM-generated.
