Difficulty :

Medium

Explanation

This question assesses your ability to design systems that remain stable and performant during high traffic periods, such as trading surges. Recruiters are looking for candidates who can use load balancing, auto-scaling, and optimized transaction processing. A strong answer will include specific tools, methodologies, and examples of managing peak traffic. Avoid failing to address the unique challenges of blockchain trading platforms, like mempool congestion or latency.

Answer Example

I ensure performance during peak traffic by implementing auto-scaling for node clusters and optimizing transaction processing through mempool prioritization. I also deploy load balancers like HAProxy to distribute requests evenly across nodes. For example, during a Bitcoin price rally, I designed a system that handled a 300% increase in trading volume by scaling nodes dynamically and optimizing database queries, maintaining sub-second latency for transactions. Continuous performance monitoring ensures the system adapts to real-time demand.
