The invention provides a state machine workflow engine based on block chain and a distributed storage working method. The working method comprises the steps of S1, judging whether a business system receives a business command of process management or not; S2, asynchronously pushing an MQ message to a data dispatcher system to asynchronously consume JSON data, and meanwhile, calling a Git corresponding command by the data dispatcher system according to a service demand to enable the Git to execute distributed storage and state machine workflow operation; and S3, after the Git returns the data to the data distributor system, the data distributor system asynchronously pushing the MQ message to enable the service system to asynchronously consume the JSON data. According to the invention, powerful distributed storage and state machine workflow are created, the development is simple and the maintenance is convenient for small and medium-sized Internet companies, most importantly, the data security, the data integrity, consistency, fault tolerance, robustness, reliability, expandability and the like can be ensured, and meanwhile, remote disaster preparation, backup and recovery in each region and the like are also realized.
