As the traditional grid data architecture develops with enterprises, its security risks will become greater and greater, and it will not be able to satisfy customers' differentiated services. Predecessors' research on the application of blockchains and nanomaterials is still insufficient. To solve the various shortcomings of the traditional power grid data governance architecture, a new type of sensor designed using blockchain technology and nanomaterials is designed through new technical means. It is applicable to the current digital grid data management architecture. The study found that the scale of the system gradually increased from 4 nodes to 16 nodes, and the TPS entered the smoothing stage after about 10, 50, 70, and 100 s, and stabilized at a small fluctuation point. We found that for every 4 nodes increase in the cluster size, the throughput drops by about 8%. Clusters of different sizes have entered a state of stable throughput. Although TPS has shown an overall downward trend of 8%, the peak situation of TPS has shown a certain different trend. This shows that the digital grid data governance network framework designed through blockchain technology and nanomaterial technology can meet the various needs of modern digital grid data centers for data center networks, such as: business scalability, reliability, security, etc.
