Cloud-Blockchain-Fusion-Framework

Implementing the framework from our paper: "CBFF: A Cloud-Blockchain Fusion Framework Ensuring Data Accountability for Multi-cloud Environments"

In this paper, we propose a Cloud-Blockchain Fusion Framework (CBFF) to relieve the “data island” between multiple clouds. CBFF improves the security of cloud data by designing the cooperation between clouds and blockchain. It designs a unified data Naming and Addressing Mechanism to publish and locate cloud data globally in a multi-cloud environment. Also, it proposes the Operation Tracing Mechanism to achieve reliable operation logging and tracing. With CBFF, we present a prototype implementation system using Hyperledger Fabric blockchain and Alibaba Cloud Computing. Our system could provide secure data uploading, sharing, and updating among multiple clouds.
