Abstract: [Abstract]　Academic evaluation is pushed to the forefront by public opinion and the biggest problem it faces is the limitations of evaluation indicators and applicability of evaluation results. How to evaluate scientifically and how to make rational use of evaluation results are the key problems that must be solved in academic evaluation. Due to the characteristics of non-tampering， decentralization， intelligent contract and transparency， the block chain technology is suitable for academic evaluation reform. Based on the transformation of academic evaluation and the functions of block chain， this paper has constructed a new academic evaluation system. The new academic evaluation system that based on block chain technology can not only absorb the real academic community as the subject of evaluation， avoid the interference of human factors， but also can affirm authors’ rights through the time stamp. What’s more， it can motivate peer review by offering tokens and carring out incentive mechanism. It can combine the advantages of qualitative evaluation and quantitative evaluation， construct citation database with high credibility and then evaluate extended products with DaaS tactics， so as to realize the transformation of academic evaluation function.
