Abstract: The Social Internet of Things (SIOT) integrates social networking principles with IOT, enabling autonomous, collaborative interactions among smart devices. while security and privacy challenges due to Heterogeneity Of devices distributed communication. Traditional blockchain-based solutions provide decentralized trust and tamper-proof transaction recording, but they largely rely on classical cryptographic algorithms, which are vulnerable to quantum computing attacks. Additionally, existing models suffer from high key generation time, inefficient block creation, and low transaction validation accuracy, limitation their scalability and reliability in large IoT networks. To address these limitations Post- Quantum Blockchain Framework for Securing Social IoT (PQBCF-SSIoT) is proposed. This framework integrates post-quantum cryptographic algorithms with optimized blockchain protocols, ensuring quantum-resistant security, efficient key generation, and reliable transaction processing. PQBCF-SSIoT enhances block creation and validation accuracy while minimizing computational overhead, making it suitable for resource-constrained IoT devices. PQBCF-SSIoT achieves a block creation accuracy of 97.5% and a block validation accuracy of 98.2%, significantly outperforming SSIoT-GAN, which reaches 94.2% creation accuracy and 95.1% validation accuracy, and OAD2D-SIoT, which achieves 92.8% creation accuracy and 93.5% validation accuracy. The proposed model achieved better performance in providing security levels.
