Specifically, the target blockchain node device receives a plurality of prescriptions sent by a plurality of prescription providing terminals deployed in a medical institution respectively, performs hash operation on a characteristic value of each prescription in the plurality of prescriptions respectively, and uses the hash value after the hash operation as a unique identifier of each prescription respectively.
It should be noted that the characteristic values in the above prescription include: the index of the prescription and the social security card number of the patient in the prescription can also comprise: the name, year and month of birth, age, and contact of the patient in the prescription.
And a third process: the target blockchain node device sends a plurality of target information to other blockchain node devices outside the blockchain node device, so that the other blockchain node devices verify the plurality of target information, wherein the target information comprises: prescriptions and unique identification of prescriptions.
Specifically, the target block chain node device sends a plurality of target information to other block chain link point devices except the target block chain link point device in the block chain network, so that the first block chain node device carries out hash operation on the characteristic value of the prescription in the first target information according to a hash function used when the target block chain link point device generates the unique identification of the prescription in the first target information, and the hash value after the hash operation is compared with the received unique identification of the prescription in the first target information sent by the target block chain link point device; the first target block link point device is any block link point device except for the target block link point device in the block chain network, and the first target information is any one of a plurality of target information.
If the hash value after the hash operation is the same as the received unique identification of the first target information sent by the target block link point device, the first target information passes verification.
And a process IV: if the plurality of target information passes the verification, the target block link point device generates a target block containing the plurality of target information.
Specifically, the blocks on the blockchain network are composed of block heads and block bodies. The block header includes the hash value of the current block, the hash value of the previous block, the timestamp and other information, and the block body includes the data information of the current block.
Taking a prescription prescribed by a doctor for a patient as an example, as shown in fig. 4, the block N has the same block structure as the block (n+1), and the prescription is stored in the block main body.
And a fifth process: the target block link point device writes the target block to the blockchain network.
Specifically, the specific manner in which a target block containing multiple target information is written to the blockchain network is described in detail below.
Firstly, taking the last block on the existing block chain network as the last block of the target block, and recording the hash value of the last block in the block head of the target block; and then recording the current time as the time stamp of the target block, and when the next new block is generated, taking the target block as the previous block of the new block, wherein the hash value of the target block is recorded in the block head of the new block. Wherein, the last block on the blockchain network refers to the block with the time of the timestamp record closest to the current time in all blocks on the blockchain network.
In summary, the objective block records the hash value of the last block and the hash value of the target block, and the objective is to ensure the non-tamper property of the prescription by utilizing the chain structure and the irreversibility of the hash encryption algorithm connected back and forth on the blockchain network.
For example, as shown in fig. 5, consider a block 1-4 on a blockchain network, where the block 1 holds the hash value H0 of the previous block, the hash value H1 of the block 1, and the data block a of the block 1, and the block 2 holds the hash value H1 of the previous block, the hash value H2 of the block 2, and the data block B of the block 2, the block 3-level block 4, and so on. For each block, the hash value of the block is calculated by performing hash operation on the data synthesized by the data block of the block and the hash value of the last block.
For example, the hash values of blocks 1-4 in fig. 5 are calculated by: h1 =hash (a|h0), h2=hash (b|h1), h3=hash (c|h2), h4=hash (d|h3), where|denotes concatenation and Hash denotes a Hash operation. In summary, it can be seen that, if a data block on any block is tampered with, the hash values on all blocks after the block on the blockchain network need to be changed according to the connection relationship between the front block and the back block. For example: if the contents of data block a on block 1 in fig. 5 are to be changed, the hash values in blocks 2, 3, 4 and Ha Xitou on subsequent blocks need to be changed accordingly. Obviously, the difficulty is high, the cost is very high, and in theory, 51% and more nodes (the nodes can create new blocks, commonly called mining nodes) on the blockchain network are controlled, so that the tampering of the data can be completed.
S303, the target block chain link point device judges whether the target prescription contains medicines.
In the embodiment of the application, the target block link point device can read out characters in the target prescription by an OCR (Optical Character Recognition, OCR) character recognition technology so as to determine whether the target prescription contains medicines.
It should be noted that before the target block link point device determines whether the target prescription contains a drug, the following steps are further performed:
Step A: the target blockchain node device does not determine a target prescription containing the identity information of the patient from a plurality of prescriptions according to the plurality of target information containing prescriptions which are pre-stored in the blockchain network;
And (B) step (B): the target block link point device sends a first indication to the medication request acquisition terminal, the first indication indicating that there is no target prescription from the plurality of prescriptions that contains the identity information of the patient.

The state of the medicine is: the drug has been dispensed, i.e., it has been delivered to the drug requestor.
It should be noted that if no drug is present in the prescription, the target blockchain node device sends a second indication to the drug acquisition request terminal, the second indication being used to indicate that no drug is present in the prescription.
S305, if the state of the medicine is to be dispensed, the target block chain link point equipment dispenses the medicine to a medicine requester; if the state of the medicine is distributed, the target block chain link point equipment sends a first prompt to the medicine acquisition request terminal; the first prompt is used for prompting that the medicine is dispensed.
In the embodiment of the present application, if the status of the drug is to be dispensed, the target block link point device dispenses the drug to the drug requester, which may specifically include, but is not limited to, the following three modes:
The first way is: if the state of the medicine is to be dispensed, the target block link point device directly dispenses the medicine to the medicine request terminal.
The second way is: if the status of the drug is to be dispensed, the target blockchain node device sends a fourth prompt to the first terminal of the drug taker, the fourth prompt being for notifying the drug taker to dispense the drug to the drug requester.
Specifically, the first terminal of the drug delivery person may include, but is not limited to: a cell phone, a computer or a pager of the drug taking person, etc.

Specifically, the application terminal may include, but is not limited to: the intelligent robot can be used for conveying medicines.
It should be noted that if the status of the drug is dispensed, the target block link point device sends a first prompt to the drug acquisition request terminal; wherein the dispensing includes: during the dispensing, the dispensing is completed.
Specifically, if the state of the medicine is in the process of dispensing, the target block chain link point device sends a second prompt to the medicine acquisition request terminal; the second prompt is used to prompt that the drug is in dispensing.
The drug is in the process of being dispensed, that is, the drug has not been delivered to the drug retrieval requester until now on its way to the drug retrieval requester.
Or alternatively
If the state of the medicine is that the dispensing is completed, the target block chain link point equipment sends a third prompt to the medicine obtaining request terminal; the third prompt is used for prompting that the medicine is dispensed.
The dispensing of the drug is complete, i.e., the drug has been delivered to the drug retrieval requester.
It should be noted that, if the status of the medicine is to be dispensed, the target block link point device modifies the status of the medicine to dispensed after the target block link point device dispenses the medicine to the medicine requester.
