Specifically, referring to fig. 3, in the case where the blood bank corresponding to the blood bank node passes the verification and blood satisfying the blood demand of the user exists, the transmitting the reservation confirmation information to the user node (step S204) includes:
and S301, under the condition that the verification is passed, the blood bank node extracts the first time and the blood requirement of the user from the signature information.
And the blood bank node verifies the signature information in the broadcast information by using the public key of the time stamp node, and when the verification is passed, the blood bank node acquires the first time in the signature information, and the first time is used as the time of queuing the user (namely the time of reserving the platelet or hemoglobin by the user).
S302, determining the reservation sequence of the user according to the first time, and determining whether blood meeting the blood requirement of the user exists in the blood bank corresponding to the blood bank node according to the reservation sequence and the blood requirement of the user.
The blood bank node inquires whether blood meeting the blood requirement of the user exists in the blood bank corresponding to the blood bank node according to the sequence of the reservation time of the user reserved in the blood bank node (the user with the previous reservation time has the priority of using platelets or hemoglobin) and the blood requirement information of the user in the broadcast information.
And S303, sending reservation confirmation information to the user when the blood bank corresponding to the blood bank node contains blood meeting the blood requirement of the user.
And if the blood bank corresponding to the blood bank node contains blood meeting the blood requirement of the user, the blood bank node sends reservation confirmation information to the user node, so that the user can confirm whether the blood bank corresponding to the blood bank node is reserved for transfusion of hemoglobin or platelets.
The first time is the time when the timestamp node receives the first HASH value HASH _ A, and the private key of the timestamp node is used for signing, so that the blood bank node uses the first time as the user queuing time, and objective, fair and reasonable user queuing time can be guaranteed.

The blood bank node acquires a first encryption result sent by the user node, and decrypts the first encryption result by using a preset algorithm to acquire the identity information of the user.
In some embodiments, the first encryption result received by the blood bank node is the first encryption result signed by using the private key of the user node, and then the blood bank node verifies the received information by using the public key of the user node, and if the verification is passed, the first encryption result is obtained.
In some embodiments, the user node encrypts the identification information of the user by using a private key of the user node according to a predetermined algorithm to obtain a first encryption result, and when the blood bank node decrypts the first encryption result, the blood bank node also decrypts by using a public key of the user node according to the predetermined algorithm to obtain the identification information of the user.
After the blood bank node acquires the user's identification information, a second HASH value HASH _ A1 is obtained through HASH calculation according to the previously acquired user's blood information and the user's identification information acquired this time.
And S403, reserving blood corresponding to the blood requirement of the user under the condition that the second hash value is the same as the first hash value, and supplying the blood to the blood bank corresponding to the blood bank node for transfusion.
Comparing the first HASH value HASH _ A with the second HASH value HASH _ A1 by the blood bank node, if the two values are equal, the appointment is real, the blood bank node appoints blood corresponding to the blood requirement of the user, and the blood platelets or hemoglobin are configured according to the blood requirement of the user (mainly the number of the blood platelets or hemoglobin required by the user) for the user to go to the blood bank corresponding to the blood bank node for platelet transfusion or hemoglobin transfusion.
The first HASH value HASH _ a is calculated by using the blood information of the user and the identification information of the user, so that the uniqueness of the first HASH value HASH _ a is ensured, and therefore, the blood bank can check the authenticity and uniqueness of the received blood demand information by using the first HASH value HASH _ a. The second HASH value HASH _ A1 is obtained by calculating a HASH value by using the user identification information sent by the user node and the user blood information acquired before, and if the first HASH value HASH _ a is equal to the second HASH value HASH _ A1, it indicates that the user identification information and the user blood information are consistent with the information reserved before, and the reservation is true and credible.
The comparison between the first HASH value HASH _ A and the second HASH value HASH _ A1 avoids that a blood vendor makes an advance reservation with own identification information, and then allows other people to use the reservation to perform platelet transfusion or hemoglobin transfusion (the identification of the blood vendor and the final platelet transfusion or hemoglobin transfusion person is obviously different, so that the first HASH value HASH _ A and the second HASH value HASH _ A1 obtained in the way are obviously different), thereby guaranteeing the benefits of patients.
