由于区块链带来的各种好处，例如安全性和隐私，因此在物联网（IoT）中采用区块链（IoT）一直在增加。当前的移动物联网区块链模型假设有固定的功能强大的边缘设备能够向网络中的所有节点提供全局通信。但是，由于物联网或网络分配问题的移动性质（NPP），节点可以移出细胞区域并分为较小的独立对等子网络。现有的区块链结构要么不支持网络分区问题或有局限性。本文介绍了一种基于图形的区块链结构，该结构利用K维时空空间，以应对在资源有限的移动网络中应用区块链的挑战。实验结果表明，与传统的基于链链的区块链结构相比，多维区块链结构可以提高可扩展性和效率，这与对数增长相似，并将最长的链长度降低超过99.99％。
The adoption of blockchain in the Internet of Things (IoT) has been increasing due to the various benefits that blockchain brings, such as security and privacy. Current blockchain models for mobile IoT assume there are fixed, powerful edge devices capable of providing global communication to all the nodes in the network. However, due to the mobile nature of IoT or network partitioning problems (NPP), nodes can move out of a cell area and split into smaller independent peer-to-peer subnetworks. Existing blockchain structures either do not support the network partitioning problem or have limitations. This paper introduces a multidimensional, graph-based blockchain structure, that utilizes k-dimensional spatiotemporal space, to address the challenges of applying blockchain in mobile networks with limited resources. Experimental results show that a multidimensional blockchain structure can improve scalability and efficiency as the blockchain grows in size, similar to logarithmic growth, and reduce the longest chain length by more than 99.99% compared to the traditional chain-based blockchain structure.
