Your question is Distributed Ledger Multi-Region Consistency. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you design a distributed ledger system to ensure data consistency across multiple regions?
Explain the consistency model, replication and consensus strategy, transaction ordering, failure handling, and recovery process. Include how you would use machine learning to detect replication anomalies or prioritize consistency incidents, and how you would evaluate and monitor the system.
