Name, quality of valuable goods and value-preserved price of valuable goods; Step 6: Based on the delivery information of the valuable goods to be delivered, the logistics distribution management center arranges the logistics outlet closest to the sender's contact address as the valuable goods collection point to collect the valuable goods to be delivered, and arranges the logistics outlet closest to the recipient's contact address. Logistics outlets serve as valuable commodity delivery outlets that deliver valuable commodities to be delivered; among them, the valuable commodity pickup outlets have pickup outlet terminal equipment connected to the logistics distribution management center, and the valuable commodity delivery outlets have delivery outlets connected to the logistics distribution management center. Terminal Equipment; Step 7: The logistics distribution management center generates the delivery waybill information for the valuable goods to be delivered, and sends the delivery waybill information to the terminal equipment of the parcel collection point; Step 8: After the terminal equipment of the parcel collection outlet obtains the physical photos and current status information of the valuable commodities that have been collected, and uses the physical photos and current status information of the valuable commodities as the initial status information of the valuable commodities, the terminal equipment of the parcel collection outlet uses the The private key encrypts the initial status information of the valuable commodity to obtain the initial status information block of the valuable commodity, and publishes the initial status information block of the valuable commodity and the corresponding private key to the valuable commodity delivery blockchain; Among them, the valuable goods distribution blockchain is formed by a logistics distribution management center, multiple participating nodes involved in the distribution of valuable goods, and a third-party certification platform that is not limited to the management of logistics companies. The participating nodes on the valuable goods distribution blockchain are Terminal equipment corresponding to any link in the entire process of distribution of valuable commodities. The multiple participating nodes participating in the distribution of valuable commodities include terminal equipment at pick-up outlets for valuable commodities and terminal equipment at delivery outlets for valuable commodities. The entire process of commodity distribution includes the collection of valuable commodities, the transportation of valuable commodities, the transshipment of valuable commodities, and the delivery of valuable commodities; the physical photos of the valuable commodities are embedded with the anti-counterfeiting traceability information of the terminal equipment of the collection outlet. , the anti-counterfeiting traceability information includes the node number of the parcel collection outlet on the valuable commodity delivery blockchain and the anti-counterfeiting traceability code belonging to the parcel collection outlet; the current status information includes the current geographical location information and ambient temperature information of the environment where the valuable commodities are located; Step 9: The terminal equipment of the parcel collection outlet sends the anti-counterfeiting traceability information embedded in the photo of the valuable commodity to the third-party certification platform for storage processing, and the parcel collection outlet transfers the valuable commodity to the next step in the entire process of valuable commodity distribution. One participating node; Step 10: After any next participating node in the entire process of delivering valuable commodities receives the valuable commodities transferred from the previous participating node, the next participating node will again collect the physical photos and current status information of the valuable commodities, and will collect After taking the physical photo and current status information of the valuable commodity as the valuable commodity delivery status information, use the private key of any next participating node to encrypt the valuable commodity delivery status information, obtain the valuable commodity delivery status information block, and add the valuable commodity delivery status information. The valuable commodity delivery status information block and the corresponding private key are published to the valuable commodity distribution blockchain; among them, the physical photo of the valuable commodity currently collected by any next participating node is embedded with the next participating node's Anti-counterfeiting traceability information, which includes the node number of any next participating node on the valuable commodity delivery blockchain and the anti-counterfeiting traceability code belonging to any next participating node; Step 11: Any of the next participating nodes will send the anti-counterfeiting traceability information embedded in the currently collected physical photos of the valuable commodities to a third-party authentication platform for storage processing, and any of the next participating nodes will store the valuables. The goods are transferred to the next participating node in the entire process of distribution of valuable goods; Step 12: The logistics distribution management center uses each private key on the valuable commodity distribution blockchain to decrypt the valuable commodity initial status information block and each valuable commodity distribution status information block respectively, and obtains the valuable commodity initial status information and valuable commodity delivery status. information; Step 13: The third-party certification platform uses each anti-counterfeiting traceability received as anti-counterfeiting traceability information for authentication, and forms a list of anti-counterfeiting traceability information for authentication from all the anti-counterfeiting traceability information for authentication; Step 14: The logistics distribution management center sends the anti-counterfeiting traceability information certification request information to the third-party certification platform; where the anti-counterfeiting traceability information certification request includes the node number corresponding to the anti-counterfeiting traceability information to be certified and the anti-counterfeiting traceability source corresponding to the node number. code; Step 15: The third-party authentication platform makes a judgment based on the received anti-counterfeiting traceability information authentication request: When the node number in the anti-counterfeiting traceability information certification request information and the anti-counterfeiting traceability code to be certified match any of the authentication anti-counterfeiting traceability information in the authentication anti-counterfeiting traceability information list, the third-party certification platform will feed back the authentication passed prompt information to the logistics Distribution Management Center; otherwise, the third-party certification platform will feedback the prompt information of failed certification to the logistics distribution management center; Among them, any participating node in the entire process of delivering valuable commodities encrypts the valuable commodity status information corresponding to any participating node in the following manner to form a valuable commodity status information block: Step S1, any participating node divides the current valuable commodity status information according to preset rules to obtain multiple valuable commodity status information fragments; among them, the current valuable commodity status information is marked as S, and the current valuable commodity status information is The information is divided into M pieces of valuable commodity status information fragments. According to the order of division, the m-th valuable commodity status information fragment is marked as S _m , S={S ₁ ,…,S _m ,…, S _M }, 1≤ m≤M, M≥3; Step S2, any participating node generates a preset number of temporary private keys, and performs a numbering process on each temporary private key, and forms a temporary private key list from all the temporary private keys after the number; among them, the preset number and the status of the valuable commodity The total number of information fragments is equal, and the temporary private key list is marked as KEY. According to the order of numbers, the m-th temporary private key is marked as key _m , KEY={key ₁ ,...,key _m ,...,key _M }; Step S3, any participating node uses the valuable commodity status information fragments with the same number and the temporary private key as the encryption processing object group to form an encryption processing object group set containing a preset number of encryption processing object groups; where, the encryption processing object The group set is marked as Z, and the m-th encryption processing object group in the encryption processing object group set is marked as Z _m , Z _m ={key _m ,S _m }, Z={Z ₁ ,…,Z _m …,Z _M }; Step S4: For the encryption processing object group set, any participating node uses the temporary private key located in the same encryption processing object group to encrypt the valuable commodity status information fragments to obtain the valuable commodity status information block set; Among them, the valuable commodity status information block set is marked as Block, Block={Block ₁ ,...,Block _m ,...,Block _M }, and Block _m is the m-th valuable commodity status information in the valuable commodity status information block set Block. block, and the valuable commodity status information block Block _m is obtained by encrypting the valuable commodity status information fragment S _m with the temporary private key key _m in the encryption processing object group Z _m ; the valuable commodity status information block Block _m includes the block header main Identifier, block header and block height. The main identifier of the block header is the number m of the valuable commodity status information block Block _m . The block header contains the hash value of the previous valuable commodity status information block Block _m-1 . The hash value and timestamp of the valuable commodity status information block Block _m , and the block height contains all valuable commodity status information within the valuable commodity status information fragment S _m ; Step S5: Any participating node publishes each valuable commodity status information block in the valuable commodity status information block set and the corresponding temporary private key in a preset order to each participant on the valuable commodity distribution blockchain. node. 2. The valuable commodity distribution management method based on blockchain technology according to claim 1, characterized in that the preset rules in step S1 are: Use the physical photo of the valuable commodity as the first valuable commodity status information fragment to be divided; Use the current geographical location information of the environment where the heavy commodity is located as the second valuable commodity status information fragment to be divided; Use the environmental temperature information of the environment where the valuable commodity is located as the third valuable commodity status information fragment to be divided; And, use the non-key information in the valuable commodity status information as the fourth valuable commodity status information fragment to be divided; among them, the non-key information is located in the valuable commodity status information and excludes the physical photos of the valuable commodity, current geographical location information and environment The remaining information after the temperature information. 3.
