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.
