Optimizing Proof-of-Work for Secure Health Data Blockchain Using Compute Unified Device Architecture
DOI: https://doi.org/10.30953/bhty.v8.421
This paper presents a GPU-accelerated Proof-of-Work (PoW) blockchain optimized using Compute Unified Device Architecture (CUDA) for secure and efficient health data management. Compared to traditional CPU mining, the CUDA-based design achieves 20–50% higher throughput and faster block formation, making blockchain practical for
high volume medical records. The system integrates AES-CTR encryption for near real time processing and ensures HIPAA compliance by storing personal data off-chain (e.g., in IPFS) to preserve privacy and the right to erasure. Validator rules mitigate Sybil attacks, and post-quantum cryptographic support ensures long-term security.
This work is particularly important for health IT
developers, blockchain researchers, digital health organizations, and policymakers seeking high-performance, privacy-preserving, and compliant blockchain solutions for healthcare data exchange and interoperability.
