step 104: and writing the block body as new logistics information into a block chain, and broadcasting to all nodes where the block chain is located.
That is to say, in the embodiment of the present invention, when the current node receives the logistics information, it is determined whether the logistics information can be decrypted; when determining that the logistics information can be decrypted, determining node information of a next node; generating a block according to the logistics information, the node information of the current node and the node information of the next node; and writing the block body as new logistics information into a block chain, and broadcasting to all nodes where the block chain is located. Compared with the prior art, in the embodiment of the invention, when each node determines that the node can decrypt the logistics information, the corresponding block can be generated according to the logistics information, the node information of the node and the node information of the next node, and the corresponding main node is not needed to be relied on, so that the safety of the logistics information can be ensured.
It should be noted that the logistics information may be a block, which may include corresponding article information, node information of a previous node, and the like, and is not described in detail herein.

It should be noted that, when the current node receives the block including the logistics information, the block may be decrypted by a private key of the current node, and when the block can be decrypted, the current node may be a transmission node of the logistics information, which is not described in detail herein.
Specifically, generating the block according to the logistics information, the node information of the current node, and the node information of the next node may specifically include:
generating an initial area block according to the logistics information, the mark information of the current node and the mark information of the next node;

For example, assuming that the logistics information is a commodity object, such as grain, the flag information of the current node is the serial number of the current node, such as 001, and the flag information of the next node is the serial number of the next node, such as 002, an initial area block may be generated according to the logistics information, the flag information of the current node, and the flag information of the next node, as shown in fig. 2, which is a schematic structural diagram of the initial area block in the embodiment of the present invention.
It should be noted that, in the embodiment of the present invention, the initial block may be signed, so that non-repudiation of the block can be achieved, and flexibility and accuracy of the block chain are ensured.
For example, as shown in fig. 3, it is a schematic structural diagram of a block body provided in the first embodiment of the present invention. Specifically, as can be seen from fig. 3, the block body may include a cryptographic block body and a hash file, so that when the current node receives the block body, the cryptographic block body may be decrypted to obtain corresponding logistics information; meanwhile, the encryption block body can be subjected to hash processing, and when the file obtained after the hash processing is determined to be consistent with the hash file in the block body, the logistics information is considered to be not tampered, so that the accuracy and the integrity of the logistics information can be determined.

It should be noted that the timestamp information may be time information representing the generation of the block (or written into a block chain), and the timestamp information may include any one or more of year information, month information, day information, time information, minute information, and second information, for example, the timestamp information may be 2018, 1, 3, 12, 20, 30 seconds, 2017/12/05/01, 20, 45, 2018/1/30, and the like, which is not limited in any way by the embodiment of the present invention.
Specifically, adding timestamp information to the block may include:
and calling a corresponding timestamp server, and acquiring timestamp information from the timestamp server.

Each time stamp is used to characterize the corresponding data message (electronic file, e.g. block) that is already present at a point in time, and is complete, verifiable, and legally effective, and will not be described in detail.
It should be noted that, in the embodiment of the present invention, any entity, including the timestamp server, cannot modify the time itself, so that authority of the time can be ensured, and tampering and subsequent repudiation of the logistics information can be avoided.
Further, when it is determined that it is capable of decrypting the logistics information, the block chain based logistics transmission method may further include:
carrying out Hash processing on the logistics information;
and if the file obtained after the hash processing is consistent with the hash file carried in the logistics information, determining that the logistics information is not tampered.
It should be noted that the hash processing in the embodiment of the present invention may include calculating a hash (hash) value of the logistics information, comparing the hash value calculated by itself with the hash value in the block, and if it is determined that the hash value calculated by itself is consistent with the hash value in the block, it may be indicated that the logistics information is not tampered and belongs to the trusted logistics information in the transmission process from the previous node to the current node, which is not described herein again.
Further, the block body may further include a random number, which is not described in detail herein.

step 508: judging whether the current node is the last node or not;
step 509: and (6) ending.
As can be seen from the above, in the embodiment of the present invention, in the first aspect, the key used by the user for encryption and decryption is stored in the hardware key or the dedicated KM system, and other people cannot obtain the key pair, so that the absolute security of the logistics information can be ensured; in the second aspect, the use of the timestamp server improves the accurate time for generating the zone block, so that the core data of the article at different stages cannot be tampered, and the method also has legal effectiveness; in the third aspect, the encryption algorithm adopts SM3 domestic cipher digest algorithm, is an improved algorithm based on SHA-256, and has higher complexity and security compared with SHA-256 algorithm; in the fourth aspect, each node is encrypted by using the public key of the next node, so that the logistics process can be carried out orderly according to a set sequence; in the fifth aspect, each node compares and verifies corresponding logistics information through a hash value, so that the correctness and the reliability of the logistics information are guaranteed.
