The invention discloses an incentive regulation and control method of a block chain network based on computing power consensus, which relates to the field of block chains and comprises the following steps: firstly, acquiring a current computing power value of the block chain network; And then, comparing the current computing power value with a preset computing power value, and if the current computing power value is not matched with the preset computing power value, adjusting the excitation level of the block chain network to enable the current computing power value to be matched with the preset computing power value. According to the method, the excitation level can be adjusted and controlled macroscopically, when the computing power is insufficient, the excitation level is high, and theenthusiasm of computing power infrastructure is improved, so that the computing power is enhanced; And when the computing power is excessive, the excitation level is reduced, the enthusiasm of the computing power infrastructure is reduced, the absent work is guided to optimize the construction scale of the computing power infrastructure, and the excess computing power is avoided.
