We propose in this paper BlockHouse, a decentralized/P2P storage system fully based on private blockchains. Each participant can rent his unused storage in order to host data of other members. This system uses a dual Smart Contract and Proof of Retrievability system to automatically check at a fixed frequency if the file is still hosted. In addition to transparency, the blockchain allows a better integration with all payments associated to this type of system ( regular payments, sequestration to ensure good behaviors of users, ...). Except the data transferred between the client and the server, all the actions go through a smart contract in the blockchain in order to log, pay and secure the entire storage process.

BlockHouse：基于区块链的分布式仓库系统

我们在本文中提出了 BlockHouse，一个完全基于私有区块链的去中心化/P2P 存储系统。每个参与者都可以租用自己未使用的存储空间来托管其他成员的数据。该系统使用双重智能合约和可检索性证明系统，以固定频率自动检查文件是否仍在托管。除了透明度之外，区块链还允许与与此类系统相关的所有支付更好地集成（定期支付、扣押以确保用户的良好行为，......）。除了客户端和服务器之间传输的数据外，所有操作都通过区块链中的智能合约来记录、支付和保护整个存储过程。
