Based on the analysis of the existing consensus mechanism of blockchain, this paper proposes a POWS mechanism based on the adjustment of workload. In the POW consensus mechanism, the concept of coinage is introduced to adjust the mining difficulty of different nodes. The POWS adjusts the mining difficulty through two factors: calculation force and coinage. The POWS is compared with the POW and the POS in two aspects, the basic performance and the ability to resist the mining pool. The experimental results show that the POWS consensus mechanism can meet the performance requirements of normal blockchain system, at the same time it can better diminish the impact of calculation force and coinage on block generate efficiency, narrow the efficiency gap between the mining pool nodes and the non-mineral pool nodes, and reduce the interest of the mining pool to non-mineral pool nodes.
