The refrigerator is simple in structure and convenient to use, food can be effectively stored according to different packages or cleanliness, neatness and convenience levels of the food, the problems like scattering and odor tainting of the food or food materials are avoided, safety and convenience in storing of the food or the food materials are improved, and the refrigerator is in conformity with use habits of users.

The present invention relates to various IC cards and a method of writing data into the IC cards. A smart card comprises a microcontroller and an interface ensuring that the smart card can communicate with a reading/writing terminal. The microcontroller comprises a microprocessor, a ROM, a RAM, an EEPROM and an I/O circuit. The ROM, the RAM, the EEPROM and the I/O circuit are connected to the microprocessor through a data bus, wherein, an exchange zone used for writing data each time is arranged inside the EEPROM. The data structure of the exchange zone comprises exchange zone control information and a data exchange zone, wherein, the exchange zone control information comprises an exchange zone data effective mark, an exchange zone data writing times counter, an exchange zone data next empty block address, a data writing target address array, a bad block counter and an exchange zone data check code. A buffer zone which corresponds to and exchanges data with the exchange zone is arranged in the RAM. The smart card of the present invention is high in data storage security, and can guarantee data writing integrity and accuracy each time.

The invention relates to the technical field of block chains, and discloses a distributed file storage method and system based on a block chain, and the method comprises the steps: meta-information ofa to-be-uploaded file carried in a file uploading request is acquired when a coordination server detects the file uploading request of a client, a coordination server obtains the file size of the to-be-uploaded file from the meta-information, formulates a corresponding fragmentation strategy according to the file size, generates a file identification code according to the meta-information, and sends the fragmentation strategy and the file identification code to a client; and the client performs fragmentation processing on the to-be-uploaded file according to the fragmentation strategy and thefile identification code to obtain fragmentation data, and uploads the fragmentation data to a block chain node corresponding to the storage server for storage so as to realize distributed storage ofthe file. Potential safety hazards caused by the fact that the to-be-uploaded file is stored in the third-party server in the prior art are avoided, the storage pressure of the storage server is reduced, and the file storage efficiency and the storage safety are improved.
