摘要/Abstract

摘要： 为了解决中心化存储带来的一系列问题，结合区块链、智能合约、闪电网络等关键技术，提出了一个应用于区块链网络环境下的去中心化存储空间交易系统。根据不同的订单情况提供3种数据编码方案，在保证用户数据安全的同时有效提高了存储节点的空间利用率和数据恢复效率，并增强了对于分布式存储复杂环境的适应性。此外，通过闪电网络搭建了链下微支付通道，设计了“一日一结”的租金交付机制，有效缓解了链上的数据存储压力。相比于以往的分布式数据共享存储系统，该系统同时支持去中心化、短时租赁和多币种支付，更能满足当前时代分布式存储空间租赁的需求。

Abstract: In order to solve problems in centralized storage, a decentralized storage space transaction system is proposed based on the key technologies of blockchain, smart contract and lightning network. Three data encoding schemes are provided for fitting different orders, thus ensuring the security of user data, improving the space utilization of storage nodes and data recovery efficiency, and enhancing the adaptability to the complex environment of distributed storages. In addition, a "one day" rental delivery mechanism is designed based on under-the-chain micro-payment channel which is built through lightning networks, effectively relieving the pressure of data storage on the chain. Compared with previous distributed data sharing storage systems, the proposed system supports decentralization, short-term lease and multi-currency payment at the same time, and shows higher ability to meet the requirements of distributed storage space lease of the current era.
