Abstract
With the ever-increasing scale of data, IP traffic of data centers will gradually suffer from a serious shortage. Centralized clouds may no longer deliver satisfactory storage services. To alleviate network pressure, transmitting source data to the edge of network instead of the remote cloud is becoming more and more important. Based on the blockchain technology, we propose a decentralized cloud storage service with tamper-resistant function. Our service provides users with metadata storage and management capabilities. In order to overcome the inherent defects of blockchain, in our design, the blockchain network has a layered and collaborative structure. After the storage capacity problem is solved, our service allows users to upload digests of source data to make the query function more user-friendly. For privacy protection, we subjoin the access management function as well. Finally, the experimental results show that the performance and availability of the blockchain network are able to support our service to provide efficient functions to users.
