description The invention provides a distributed storage data protection method and system based on a block chain, and relates to the technical field of block chains and distributed storage, and the method comprises the steps that a leaf node obtains the use frequency of all disks in a disk cluster, and a center node calculates the average value of the disk use frequency based on the use frequency; and the central node determines a data protection mode of each disk in a disk cluster based on the average value of the disk use frequency, adds the data protection mode into block information and sends the block information to each node of a block chain. Different storage data protection modes are adopted according to the use frequency of files, the network erasure code technology is adopted for the low frequency, and the three-copy technology is adopted for the high frequency. The advantages of high error-tolerant rate and low redundancy of the network erasure code can be brought into full play, and calculation storm caused
