The consensus mechanism, as the basic rules on Blockchain, along with the cryptography and data storage structures, are called three key technologies of Blockchain. In recent years, the application areas of blockchain technology have been further expanded due to the development of smart contracts. The personalized design and improvement on consensus mechanisms, which make them more applicable to actual industries, have become a research focus in the field of blockchain application. The theoretical background of this paper is a Smart Industry based on Alliance Blockchain, in which smart contracts are signed among network nodes to automate transaction processes. In this paper, a new consensus mechanism named Delegate Proof of Job-Relevance(DPoJ) is proposed, the activity and professionalism of nodes are emphasized, the application areas of smart contracts are innovatively classified, the JobRelevance of nodes is calculated as a parameter in equity calculation in the process of consensus. Next, the influence of Job-Relevance on the growth rate of nodes’ equities under DPoJ consensus is analyzed from the perspective of game theory and mechanism design. At last, it is proved that in most cases, rational nodes are more inclined to increase their equities in the process of consensus by improving their Job-Relevance.
