Node Trusted Computing Mechanism Design and Application under the Main-side Blockchain Architecture

The power system can combine the decentralization, openness, transparency, traceability and other characteristics of the blockchain to promote the further development of the power system in the future. At present, distributed power transactions based on blockchain have received extensive attention. With the sharp increase of the main body of electricity, in order to improve the transaction rate and storage capacity, the main-side blockchain transaction structuring is starting to get attention. However, how to design a trusted computing mechanism to identify malicious nodes under the main-side blockchain transaction architecture is an urgent problem to be solved. Based on this, this paper designs a new time-constrained intra-domain and cross-domain credibility mechanism for the main-side blockchain nodes under the main-side blockchain architecture. Using this credibility mechanism can effectively find malicious nodes and quickly realize the trusted computing for nodes. Experiments show that the intra-domain and cross-domain credibility mechanism designed in this paper has little effect on the throughput and delay of the main-side blockchain transactions. In particular, this paper designs a unique cross-domain credibility mechanism, it can more effectively identify malicious nodes and greatly reduce cross-domain nodes becoming malicious node.
