Cloud storage environment based on distributed operation requires high consistency for data copies stored on many servers and client terminals. At present, various data and file synchronization tools can adapt to most application scenarios, but there are still some problems, such as high efficient data synchronization, rapid verification of synchronization results, free access to synchronized files, high availability of the master node, etc. This paper proposes an innovative cloud storage's folders and files synchronization Model: ChainFileSynch, which contains a fast cloud storage file synchronization architecture, process and processing algorithm based on Blockchain. The architecture makes full use of Blockchain distribution and traceability: the consensus mechanism and the like implement synchronization of cloud storage based on cloud file transactions. Compared to other traditional cloud synchronization technologies, ChainFileSynch improves cloud storage synchronization efficiency, data synchronization verification and network reliability.
