    Design a function that determines the minimum processing capacity (in number of transactions) needed for the fraud detection system, where the capacity must be a power of 2 and sufficient to handle n concurrent transactions without overflow. The system requires this calculation to efficiently allocate memory blocks and optimize parallel processing resources for real-time transaction analysis.
