The invention discloses a multi-signature transaction information processing method for a data transaction platform based on a block chain. Each of a buyer and a seller generates a transaction key pair at self client, and the data transaction platform generates and distributes a single transaction key pair for each transaction process; the seller releases data to be transacted on the block chain via the data transaction platform; after the buyer submits a transaction application, an intermediate address is generated according to a three-party public key, money is transferred to the intermediate address after payment, and the seller receives the money, writes the money into the block chain, then encrypts data and sends the encrypted data to the buyer; after the buyer receives the data, if transaction is acknowledged, the double parties sign, and the money is transferred to the address of the seller; and if objection exists, the data transaction platform makes a judgment, and determines to transfer the money to the buyer or the seller according to the judgment result. Data and transaction information during transaction of the double parties are processed in a special regional chain manner, and meanwhile, the data transaction platform cannot embezzle the transaction money, so that the security of digital assets during transaction is further guaranteed.

The invention discloses a rotating-type grain distributor and a granary provided with the grain distributor, and belongs to the technical field of granaries. The rotating-type grain distributor comprises a grain collecting barrel. The grain collecting barrel comprises a barrel wall and a barrel bottom. The outer side of the barrel wall of the grain collecting barrel is provided with two downward-inclined grain sliding pipes. The bottom face and one side face of each grain sliding pipe are curved surfaces which are of an integral structure. When the rotating-type grain distributor is used, the rotating-type grain distributor is arranged at a grain inlet of the granary, after grain enters the grain collecting barrel, the grain flows into the grain sliding pipes, and when the rotating-type grain distributor rotates, the grain sliding pipes rotate along with the rotating-type grain distributor. Due to the fact that the bottom face and one side face of each grain sliding pipe are curved surfaces which are of the integral structure, when the rotating-type grain distributor rotates, under the effect of centrifugal force and tangential force generated by the curved surfaces, the grain is scattered and flows out of the grain sliding pipes, and the grain falls onto a circular cross section of the granary. According to the rotating-type grain distributor, the impurity accumulation caused by automatic grading formed by concentrated falling of the grain is alleviated, and the safe storage of the grain is guaranteed.
