Balancing Privacy and Performance - Dual Dynamic Adjustment (DDA)

The Dual Dynamic Adjustment (DDA) mechanism addresses the high computational demands of TFHE-encrypted data. TFHE significantly inflates ciphertext and requires intensive Boolean algebra and FFT operations, creating challenges for general hardware and increasing computational inequities.

DDA categorizes blocks into high-privacy and standard types. High-privacy blocks process TFHE-encrypted data with elevated thresholds for security, while standard blocks have lower computational requirements, enabling broader hardware participation and promoting decentralization. Parallel block generation ensures network fluidity, allowing simultaneous processing of both block types and mitigating delays.

By dynamically adjusting block difficulty and resources based on computational and privacy needs, DDA balances efficiency, decentralization, and data privacy, providing a stable foundation for secure and scalable blockchain operations.
