Blockchain is one of the most heavily invested technologies in recent years. Due to its tamper-proof and decentralization properties, blockchain has become an ideal utility for data storage that is applicable in many real world industrial scenarios. One important scenario is web log, which is treated as sources of technical significance and commercial revenues in major internet companies. In this paper, we illustrate our design of a web log storage system based on HyperLedger. HyperLedger yields higher throughput and lower latency compared with other blockchain systems. Alongside its efficiency advantages, HyperLeger is a permissioned blockchain, which is an ideal fit for enterprise software design scenario.

There are a lot of land and resources data. However, it is difficult to share these data due to a variety of reasons such as lacking of unified standards, common semantics, diverse sources and independent management and etc. In this paper we analyze all data for land and resources, studies the consolidation method for mass data from multi-sources of land and resources, solve several key issues such as unified framework, data indexing, mass data storage etc. Finally three database including the original database, basic database, application database, are established and above the three databases a management system is built up. These efforts contributed to "a map" project's completion and the process of land and resources information of Chongqing Municipality.
