Performance Considerations and Optimization

When we talk about quantum-resistant ledger systems, performance considerations are key. They help keep digital transactions and data safe and sound. It's important to weigh the speed vs. security trade-offs when using these systems.

To boost performance, we can try a few things. For example, parallel processing breaks down big tasks into smaller ones. This lets many nodes work at the same time. Also, load balancing algorithms help spread out requests evenly, based on how busy each node is.

Here are some ways to improve performance:

• Using sharding to split big datasets into smaller parts. This cuts down on wait times when accessing data across different nodes.
