Tang, Yuzhe, Zou, Qiwu, Chen, Ju, Li, Kai, Kamhoua, Charles A., Kwiat, Kevin, Njilla, Laurent.  2018.  ChainFS: Blockchain-Secured Cloud Storage. 2018 IEEE 11th International Conference on Cloud Computing (CLOUD). :987–990.
This work presents ChainFS, a middleware system that secures cloud storage services using a minimally trusted Blockchain. ChainFS hardens the cloud-storage security against forking attacks. The ChainFS middleware exposes a file-system interface to end users. Internally, ChainFS stores data files in the cloud and exports minimal and necessary functionalities to the Blockchain for key distribution and file operation logging. We implement the ChainFS system on Ethereum and S3FS and closely integrate it with FUSE clients and Amazon S3 cloud storage. We measure the system performance and demonstrate low overhead.
