Worst Case Analysis

Definition

Worst case analysis is a method of evaluating a system or algorithm’s performance under the most unfavorable conditions possible. In blockchain and distributed systems, this involves assessing how a protocol behaves when faced with maximum network latency, numerous faulty nodes, or severe adversarial attacks. This analysis is critical for determining the absolute minimum guarantees of security, reliability, and performance. It helps designers ensure system robustness against extreme scenarios.
