Summary:The invention relates to a modular index outsourcing fair payment method based on a block chain, and the method comprises the steps: firstly, a user calls a subprogram to generate random data and a random blind pair; and then, the user splits the privacy data and the random data by using random blinding, and uploads the segmented data needing to be calculated to the block chain. The cloud server downloads and calculates, and submits a result to the block chain; and finally, the user downloads and verifies the result. If the outsourcing result is correct, the user obtains the required outsourcing result; otherwise, the user applies for the block chain for arbitration so as to judge whether the server is malicious or not. If the block chain judges that the server really has the malicious behavior, deducting the guarantee deposit of the server; and if the block chain judges that the calculation of the server is correct, the protocol fails. According to the method provided by the invention, a user can solve the d
