The Internet of Things has transformed industries, cities, and homes through a vast network of interconnected devices. As the IoT expands, the number of devices is projected to reach tens of billions, generating massive amounts of data. This growth presents significant data storage, management, and security challenges, especially in large-scale deployments such as smart cities and industrial operations. Traditional centralized solutions struggle to handle the high data volume and heterogeneity of IoT data, while ensuring real-time processing and interoperability. This paper presents the design, development, and evaluation of a blockchain framework tailored for the secure storage and management of data generated by IoT devices. Our framework introduces efficient methods for managing, transmitting, and securing data packets within a blockchain-enabled IoT network. The proposed framework uses a gateway node to aggregate multiple data packets into single transactions, increasing throughput, optimizing network bandwidth, reducing latency, simplifying data retrieval, and improving scalability. The results obtained from rigorous analysis and testing of the evaluated scenarios show that the proposed blockchain framework achieves a high level of performance, scalability, and efficiency while ensuring robust security being able to integrate a large number of IoT devices in a flexible manner.
物联网通过庞大的互联设备网络改变了行业、城市和家庭。随着物联网的扩展，设备数量预计将达到数百亿，产生海量数据。这种增长带来了重大的数据存储、管理和安全挑战，尤其是在智能城市和工业运营等大规模部署中。传统的集中式解决方案难以处理物联网数据的高数据量和异构性，同时还要确保实时处理和互操作性。本文介绍了一种专门为物联网设备生成的数据的安全存储和管理量身定制的区块链框架的设计、开发和评估。我们的框架引入了在支持区块链的物联网网络中管理、传输和保护数据包的有效方法。所提出的框架使用网关节点将多个数据包聚合为单个交易，提高了吞吐量，优化了网络带宽，减少了延迟，简化了数据检索，并提高了可扩展性。从对评估场景的严格分析和测试中获得的结果表明，所提出的区块链框架在确保强大安全性的同时，实现了高水平的性能、可扩展性和效率，能够灵活地集成大量物联网设备。
