For example, in a two-player game scenario, the random number generated based on the hardware condition of the device is often not meaningful as a criterion for determining the game result. The random number is generated based on the hardware condition of the device, so that the random number is not determined by both game parties, and the game result is judged by the random number, so that the game result has no public credibility.

The first random seed belongs to the first interval, and the second random seed belongs to the second interval.
In the technical scheme, the block link point device determines that the random number and the first random seed are in the same interval and the random number and the second random seed are in different intervals by judging that the random number is in the first interval, so that the priority judgment result is that the priority of the first client is higher than that of the second client. The priority evaluation result is obtained by judging whether the random number and the random seed are in the same interval, so that the priority evaluation result can be relied on.

Detailed Description
The embodiments of the present invention will be described below with reference to the drawings.
As random numbers are widely used in various aspects of real life, methods for generating random numbers become more and more important parts of people. Generally, random numbers can be applied in lottery, gaming, or generating winning numbers. For example, in a scenario of two-player game, two players of the game do not trust each other, a random number needs to be generated, and the random number is used as a criterion for determining win-or-lose of the two players of the game, so as to obtain a game result. The embodiment of the present invention is illustrated by taking a two-player game scenario as an example, and does not limit the present invention.
The traditional two-person game scene mainly relates to a first game party, a second game party and a third judging party, wherein under the condition that the first game party and the second game party are not trusted with each other, the third judging party generates a random number based on the hardware condition of equipment, and as the game parties do not participate in the generation process of the random number, the game result obtained by utilizing the random number has no public trust.
For example, two people each hold a card, neither person knows the size of the opponent's card, a random number is given by the third judge based on the hardware condition of the device, and the game result is obtained by using the random number. It can be seen that the random number given by the third judge is completely a random number generated based on the hardware condition of the device, and the two parties of the game do not participate in the generation of the random number, so that the game result may cause an adverse result to one party of the game.
in order to solve the above problems, the embodiment of the present invention introduces a block chain technique into a game scenario, and provides a priority evaluation method, where the priority evaluation method specifically includes: the blockchain node device receives a first check value from the first client regarding the first random seed and receives a second check value from the second client regarding the second random seed; the blockchain node device receives a first random seed from a first client and receives a second random seed from a second client; the block chain node equipment verifies a first check value of the first random seed and a second check value of the second random seed; if the verification is passed, the block chain node equipment generates priority evaluation results of the first client and the second client according to the random numbers, and sends the priority evaluation results to the first client and the second client, wherein the priority evaluation results are used for indicating the priorities of the first client and the second client. In a game scene, the random number generated by the method is used as a standard for judging the game, so that the game result is more fair.
Therefore, the first client sends the first check value of the first random seed to the blockchain node device first, and then sends the first random seed to the blockchain node device, so that the first random seed is not modified, and the reliability of the first random seed is ensured. The beneficial effect that the second client sequentially sends the second check value and the second random seed to the blockchain node device is the same as the beneficial effect, and the description is omitted here.
The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm, and has the characteristics of decentralization, openness, independence, safety, anonymity and the like. The blockchain may include a plurality of node devices, and each of the plurality of node devices may store a block issued to the blockchain network, thereby implementing distributed storage of data. The block chain technology realizes decentralization, does not depend on an additional third-party management mechanism or hardware facilities, has no central control, and realizes self-verification, transmission and management of information by each node through distributed accounting and storage except for the self-integrated block chain.
in order to better understand a method for generating random numbers disclosed in the embodiments of the present invention, a communication system to which the embodiments of the present invention are applicable is first described below.
referring to fig. 1, fig. 1 is a schematic diagram of a priority evaluation system according to an embodiment of the present invention. As shown in fig. 1, the priority evaluation system includes: at least one client, at least one blockchain node device. The at least one block chain node device may comprise one or more of a block chain node device 1, a block link point device 2, and a block link point device 3, the block link point device 1, the block link point device 2, and the block link point device 3 forming a block chain network.
Taking the example that the priority evaluation system includes the block link point device, the first client, and the second client, the block link point device may be any one of the block chain node device 1, the block link point device 2, and the block link point device 3. The blockchain node device may receive a first check value from a first client and a second check value from a second client, and then the blockchain node device may receive a first random seed from the first client and a second random seed from the second client. The blockchain node device may verify a first check value of the first random seed and a second check value of the second random seed. If the verification is passed, the block link point device can generate a random number according to the first random seed and the second random seed, generate a priority evaluation result based on the random number, and send the priority evaluation result to the first client and the second client.
Taking the priority evaluation system including the first block link point device, the second block link point device, the first client, and the second client as an example, the first block link point device or the second block link point device may be any one of the block chain node device 1, the block link point device 2, and the block link point device 3, and the first block link point device and the second block link point device are different block link point devices.
For example, the first block-linked-point device may uplink the first check value after receiving the first check value from the first client, and then the first block-linked-point device may uplink the first random seed after receiving the first random seed from the first client. The second block-link point device may obtain the first check value and the first random seed on the chain, and the second block-link point device sequentially receives the second check value and the second random seed from the second client. And then, the second block link point equipment verifies the first check value of the first random seed and the second check value of the second random seed. And if the verification is passed, the second block chain node equipment generates a random number according to the first random seed and the second random seed, generates a priority evaluation result based on the random number, and sends the priority evaluation result to the first client and the second client. Optionally, the second blk device may forward the priority evaluation result to the first client through the first blk device.
for another example, after the first parity value and the first random seed are sequentially received from the first client, the first block-node device may send the first parity value and the first random seed to the second block-node device. After the second block link point device receives the second check value and the second random seed from the second client in sequence, the first check value of the first random seed and the second check value of the second random seed may be verified. If the verification is passed, the second block link point device may generate a priority evaluation result based on the random number. The manner of generating the priority evaluation result in the embodiment of the present application is the same as the manner of generating the priority evaluation result in the embodiment described above, and the embodiment of the present application is not described again.
taking the priority evaluation system including the first block link point device, the second block link point device, the third block link node device, the first client and the second client as an example, the first block link point device, the second block link point device or the third block link node device may be any one of the block link node device 1, the block link point device 2 and the block link point device 3, and the first block link point device, the second block link point device and the third block link node device are different block link point devices. The first block-link-point device may uplink the first check value and the first random seed in the above manner, and the second block-link-point device may uplink the second check value and the second random seed in the above manner. And then, the third block chain node equipment acquires the first check value and the second check value or the first random seed and the second random seed on the chain, verifies the first check value of the first random seed and the second check value of the second random seed, and generates a priority evaluation result of the first client and the second client according to the random number if the verification is passed. The manner in which the third block link node device generates the priority evaluation result is the same as the manner in which the second block link node device generates the priority evaluation result in the above embodiment, and details are not repeated in this embodiment.
The third blockchain node device may send the priority evaluation result to the first client and the second client. Optionally, the third blockchain node device may forward the priority evaluation result to the first client or the second client through the first blockchain node device or the second blockchain node device.
Taking the example that the priority evaluation system includes the block link point device and the client, the block link point device may be any one of the block link node device 1, the block link point device 2, and the block link point device 3. The client may send the first check value and the first random seed to the blockchain node device in sequence when detecting the operation of the first user. The client may further send the second check value and the second random seed to the blockchain node device in sequence when detecting the operation of the second user. The method for generating the priority evaluation result by the block link point device is the same as the method for generating the priority evaluation result by the block link point device in the above embodiment, and the description of the embodiment of the present application is omitted.
Referring to fig. 2, fig. 2 is a schematic flow chart of a priority evaluation method according to an embodiment of the present invention, the method includes, but is not limited to, the following steps:
Step S201: the first client acquires a first random seed.
specifically, the first client receives a first random seed from the first user, and generates a first check value based on the first random seed.
in one implementation, the first client may obtain a first random seed from the block link point device, and generate a first check value according to the first random seed. Wherein the block link point device stores at least one random seed.
In one implementation, when the first client detects a first user operation, a first random seed is generated based on a pseudo-random number generator to obtain the first random seed, and then a first check value is generated according to the first random seed.
Step S202: the first client generates a first check value based on the first random seed.
in an implementation manner, the first check value may be a first hash value, that is, the first client generates a first hash value of the first random seed according to a hash algorithm, and sends the first hash value to the blockchain node device. Common hashing algorithms include: a Message Digest algorithm (Message Digest 4, MD4), a Secure hash algorithm 1(Secure HashAlgorithm 1, SHA-1), and the like, and the embodiment of the present invention does not limit which hash algorithm is specifically used.
Step S203: and the first client sends the first check value to the blockchain node equipment.
Step S204: the second client obtains a second random seed.
Step S205: the second client generates a second check value based on the second random seed.
Step S206: and the second client sends the second check value to the blockchain node equipment.
Specifically, the execution sequence of steps S204 to S206 and steps S201 to S203 is not sequential, and the execution process of the second client in steps S204 to S206 is the same as the execution process of the first client in steps S201 to S203, which is not described herein again.
Step S207: and the first client sends the first random seed to the blockchain node equipment.
Step S208: and the second client sends the second random seed to the blockchain node equipment.
It should be noted that the block link node device may receive the first check value and the first random seed of the first client in sequence, and then receive the second check value and the second random seed of the second client in sequence; the blockchain node device may further receive the first check value of the first client and the second check value of the second client, and then receive the first random seed of the first client and the second random seed of the second client, which is not limited in the embodiment of the present invention.
Step S209: and the block chain node equipment verifies the first check value and the second check value.
Specifically, the block link point equipment generates a third check value according to the first random seed and generates a fourth check value according to the second random seed; and when the third check value is the same as the first check value and the fourth check value is the same as the second check value, determining that the verification is passed.
In one implementation, the first check value from the first client may be a first hash value, the second check value from the second client may be a second hash value, and the block link point device performs a hash algorithm on the first random seed to obtain a third hash value; and the block chain node equipment performs a hash algorithm on the second random seed to obtain a fourth hash value. And when the third hash value is the same as the first hash value and the fourth hash value is the same as the second hash value, determining that the verification is passed.
step S210: and if the verification is passed, the block link point equipment generates a random number according to the first random seed and the second random seed.
Specifically, if the block link point device determines that the third check value is the same as the first check value and the fourth check value is the same as the second check value, the block link point device generates a random number according to the first random seed and the second random seed, so that the reliability of the first random seed and the second random seed can be ensured.
if the third check value is different from the first check value, the block link point device determines that the first client modifies the first random seed after sending the first check value, and then generates first prompt information and sends the first prompt information to the first client and the second client, wherein the first prompt information is used for prompting that the first client has wrong operation.
If the fourth check value is different from the second check value, the block link node device determines that the second client modifies the second random seed after sending the second check value, and then generates second prompt information and sends the second prompt information to the first client and the second client, wherein the second prompt information is used for prompting that the second client has an error operation.
Therefore, by comparing that the third check value is the same as the first check value and the fourth check value is the same as the second check value, the block link point device can ensure the reliability of the first random seed and the second random seed, thereby realizing fairness and justice of the priority evaluation result.
step S211: and the block chain node equipment generates a priority evaluation result according to the random number, wherein the priority evaluation result is used for indicating the priority of the first client and the priority of the second client.
Specifically, the block link point device compares the random number with the first random seed and the second random seed to obtain a priority evaluation result, where the priority evaluation result is used to indicate that the priority of the first client is higher than the priority of the second client, or that the priority of the first client is lower than the priority of the second client.
For example, in the two-player game scenario, if the priority evaluation result indicates that the priority of the first client is higher than the priority of the second client, the first game party corresponding to the first client is a winner, and the second game party corresponding to the second client is a loser. And if the priority evaluation result shows that the priority of the first client is lower than that of the second client, the first game party corresponding to the first client is a loser, and the second game party corresponding to the second client is a winner.
Step S212: and the block chain node equipment sends the priority evaluation result to the first client and the second client.
specifically, after the block link point device obtains the priority evaluation result, the block link point device sends the priority evaluation result to the first client and the second client.
In one implementation, after obtaining the priority evaluation result, the block link point device may generate a notification message based on the priority evaluation result, and send the notification message to the first client and the second client, where the notification message is used to indicate the priority evaluation result.

step S304: the second client obtains a second random seed.
step S305: the second client generates a second check value according to the second random seed.
Step S306: and the second client sends the second check value to the blockchain node equipment.
Specifically, the execution sequence of steps S304 to S306 and steps S301 to S303 is not sequential, and the execution process of the second client in steps S304 to S306 is the same as the execution process of the first client in steps S301 to S303, which is not described herein again.
step S307: and the first client sends the first random seed to the blockchain node equipment.
Step S308: and the second client sends the second random seed to the blockchain node equipment.
It should be noted that the block link node device may receive the first check value and the first random seed of the first client in sequence, and then receive the second check value and the second random seed of the second client in sequence; the blockchain node device may further receive the first check value of the first client and the second check value of the second client, and then receive the first random seed of the first client and the second random seed of the second client, which is not limited in the embodiment of the present invention.
Step S309: and the block chain node equipment verifies the first check value and the second check value.
Specifically, the execution process of step S309 may refer to step S209 in fig. 2, which is not described herein again.
Step S310: and if the verification is passed, the block link point equipment generates a random number according to the first random seed and the second random seed.
Specifically, when the third check value is the same as the first check value and the fourth check value is the same as the second check value, the block link point device calculates the first random seed and the second random seed to obtain the random number.
in one implementation, the block link point device may perform an arithmetic operation on the first random seed and the second random seed to obtain an arithmetic operation result, and use the arithmetic operation result as a random number. Optionally, the first random seed and the second random seed are subjected to subtraction, and a result obtained through the subtraction is used as a random number. For example, if the first random seed is 12 and the second random seed is 7, the subtraction result between the first random seed and the second random seed is 5, and 5 is taken as the random number. Optionally, after the first random seed and the second random seed are subjected to subtraction, division is performed on a subtraction result to obtain a random number. For example, if the first random seed is 12 and the second random seed is 7, the subtraction result between the first random seed and the second random seed is 5, and the value obtained by dividing 5 by 2 is 2.5, and then 2.5 is used as the random number.
It should be noted that, the operation rule for performing the operation on the first random seed and the second random seed is various, and the embodiment of the present invention does not limit this.
Step S311: and the block chain node equipment generates an intermediate number according to the first random seed and the second random seed, and determines a first interval and a second interval according to the intermediate number.
Specifically, the block link point device calculates the first random seed and the second random seed to generate a middle number, a lower limit value of the first interval, and an upper limit value of the first interval. The block chain node device may determine the first section and the second section by setting the intermediate number as an upper limit of the first section and setting the intermediate number as a lower limit of the second section.
In one implementation, the operating the first random seed and the second random seed by the block link point device to determine the first interval and the second interval may include: the block chain node equipment calculates the average value of the first random seed and the second random seed to obtain the average value of the first random seed and the second random seed, and the average value is used as an intermediate number; adding the first random seed and the second random seed by the block chain node equipment to obtain a first numerical value, taking the opposite number of the first numerical value, and taking the opposite number as the lower limit of a first interval; the blockchain node device takes the first value as an upper limit of the second interval. As can be seen from the above, the lower limit of the first interval is the inverse of the first value, and the upper limit of the first interval is the average value of the first random seed and the second random seed; the lower limit of the second interval is an average value of the first random seed and the second random seed, and the upper limit of the second interval is a first value.
for example, in a game scenario, if the first random seed of the first game party is 13 and the second random seed of the second game party is 3, the first random seed and the second random seed are subjected to an average value algorithm to obtain an intermediate number of 8, and the first random seed and the second random seed are added to obtain a first value of 16. Then the lower limit of the first interval is-16 and the upper limit of the first interval is 8; the lower limit of the second interval is 8 and the upper limit of the second interval is 16, that is, the first interval is [ -16,8 ], and the second interval is [8,16 ].
It should be noted that, the block link point device may perform various rules on the first random seed and the second random seed to obtain the middle number, the lower limit value of the first interval, and the upper limit value of the first interval, and the embodiment of the present invention does not limit the operation rules.
Therefore, the ranges of the first interval and the second interval are determined by calculating the first random seed and the second random seed, and the first random seed and the second random seed can be ensured to participate in the generation process of the first interval and the second interval, so that the ranges of the first interval and the second interval are related to the random seeds, and the priority evaluation result can be determined.
step S312: and when the random number is positioned in the first interval, generating a priority evaluation result, wherein the priority evaluation result is used for indicating that the priority of the first client is higher than that of the second client.
Specifically, the block link point device judges whether the relation between the random number and the first random seed and the second random seed meets a first preset rule according to the first preset rule, and obtains a priority judgment result.
In one implementation, the block link point device generates an intermediate number according to the first random seed and the second random seed; determining a first interval and a second interval according to the intermediate number, wherein the first random seed belongs to the first interval, and the second random seed belongs to the second interval; and when the random number is positioned in the first interval, generating a priority evaluation result, wherein the priority evaluation result is used for indicating that the priority of the first client is higher than that of the second client.
Assume that the first predetermined rule is: and when the random number and a certain random seed are positioned in the same interval, the client corresponding to the random seed is considered as the client with higher priority. That is to say, the block link point device determines that the random number is located in the first interval or the second interval, if the random number is located in the first interval, the block link point device considers that the random number and the first random seed are located in the same interval, and the random number and the second random seed are located in different intervals, and then the block link node device obtains a priority evaluation result according to the above process, wherein the priority evaluation result is used for indicating that the priority of the first client is higher than the priority of the second client.
For example, in a scenario of a two-player game, the first random seed provided by the first gaming party is 12, the second random seed provided by the second gaming party is 8, then the first interval is [ -20,10 ], the second interval is [10,20], wherein the first random seed 12 is located in the second interval and the second random seed 8 is located in the first interval. The random number obtained by the block chain node device through subtraction operation of the first random seed and the second random seed is 4, and it can be known that the random number 4 and the second random seed 8 are located in a first interval [ -20,10 ], and the random number 4 and the second random seed 12 are located in different intervals. The priority evaluation result obtained by the block link point device is as follows: the second client has a higher priority than the first client.
It should be noted that the foregoing example is only used to illustrate that, when the block chain node point device is located in the same interval as the random seed of a certain party in the game based on the random number, the priority of the client corresponding to the random seed is determined to be higher, and in other feasible implementation manners, the block chain node point device may also be configured to determine that, when the random number is located in the same interval as the random seed of the certain party in the game, the priority of the client corresponding to the random seed is determined to be lower.
Therefore, by comparing whether the random number and the random seed are in the same interval or not, the random seed which is closer to the difference value of the random number can be obtained, and the priority of the client corresponding to the random seed is judged to be higher, so that the priority judgment result can be relied on.
Step S313: and the block chain node equipment sends the priority evaluation result to the first client and the second client.
Specifically, the execution process of step S309 can refer to step S208 in fig. 2, which is not described herein again.
Therefore, by implementing the embodiment of the present invention, both the first random seed of the first client and the second random seed of the second client participate in the generation process of the random number, and the block link point device obtains the priority levels of the first client and the second client by determining whether the random number is in the same interval as the first random seed of the first client or the second random seed of the second client, so as to obtain the priority level evaluation result, and sends the priority level evaluation result to the client. The random seeds of the two game parties participate in the game process in the game scene, and the game parties in the two game parties are judged to have higher priority with the random seeds and the random numbers in the same interval, so that the game result is fair.
Fig. 4 is a schematic flowchart of another priority evaluation method provided in an embodiment of the present invention, which includes but is not limited to S401 to S409, where:
Step S401: the first client acquires a first random seed.
Specifically, the execution process of step S401 may refer to step S201 in fig. 2, which is not described herein again.
Step S402: the first client generates a first check value according to the first random seed.
Specifically, the execution process of step S402 can refer to step S202 in fig. 2, which is not described herein again.
Step S403: and the first client sends the first check value to the blockchain node equipment.
Specifically, the execution process of step S403 may refer to step S203 in fig. 2, which is not described herein again.
Step S404: the second client obtains a second random seed.
step S405: the second client generates a second check value according to the second random seed.
Step S406: and the second client sends the second check value to the blockchain node equipment.
Specifically, the execution sequence of steps S404 to S406 and steps S401 to S403 are not in sequence, and the execution process of the second client in steps S404 to S406 is the same as the execution process of the first client in steps S401 to S403, which is not described herein again.
step S407: and the first client sends the first random seed to the blockchain node equipment.
Step S408: and the second client sends the second random seed to the blockchain node equipment.
It should be noted that the block link node device may receive the first check value and the first random seed of the first client in sequence, and then receive the second check value and the second random seed of the second client in sequence; the blockchain node device may further receive the first check value of the first client and the second check value of the second client, and then receive the first random seed of the first client and the second random seed of the second client, which is not limited in the embodiment of the present invention.
Step S409: and verifying the first random seed and the second random seed by the blockchain node equipment.
Specifically, the execution process of step S405 may refer to step S205 in fig. 2, which is not described herein again.
Step S410: and if the verification is passed, the block link point equipment generates a random number according to the first random seed and the second random seed.
specifically, if the third check value is the same as the first check value and the fourth check value is the same as the second check value, the block link point device operates the first random seed and the second random seed to obtain a random number.
in one implementation, the block link point device performs binary conversion on the first random seed to obtain a second numerical value, and the block link point device performs binary conversion on the second random seed to obtain a third numerical value; the block chain node equipment performs logical operation on the second numerical value and the third numerical value to obtain a logical operation result; and performing decimal conversion on the logical operation result to obtain the random number.
For example, in a two-player gaming scenario, the first random seed held by the first gaming party is 7 and the second random seed held by the second gaming party is 9. The block chain node equipment performs binary conversion on the first random seeds to obtain a second numerical value of 0111, and similarly, the block chain node equipment performs binary conversion on the second random seeds to obtain a third numerical value of 1001; the block chain node equipment performs exclusive-or operation on the second numerical value 0111 and the third numerical value 1001 to obtain an exclusive-or operation result 1110; the block chain node device performs decimal conversion on the exclusive or operation result 1110 to obtain a random number of 14.
It should be noted that the binary conversion or the decimal conversion may be replaced by other binary conversion operations, which is not limited in the embodiment of the present invention.
Therefore, the block chain node point equipment performs binary conversion on the first random seed and the second random seed, performs binary logic operation on the conversion result, performs decimal conversion on the logic operation result, and finally obtains the random number. The random number generated by a complex method can not be predicted by lawbreakers, so that the fairness of priority evaluation results is ensured.
step S411: calculating the random number and the first random seed to obtain a fourth numerical value; and operating the random number and the second random seed to obtain a fifth numerical value.
in one implementation, the block link point device may operate the random number with the first random seed, and operate the random number with the second random seed by: carrying out subtraction operation on the random number and the first random seed to obtain a fourth numerical value, and carrying out subtraction operation on the random number and the second random seed to obtain a fifth numerical value; comparing the fourth numerical value with the fifth numerical value to obtain a comparison result; and generating a priority evaluation result according to the comparison result.
Step S412: and when the fourth numerical value is larger than the fifth numerical value, generating a priority evaluation result, wherein the priority evaluation result is used for indicating that the priority of the first client side is lower than that of the second client side.
Specifically, the block chain node point equipment calculates the fourth numerical value and the fifth numerical value, and generates a priority evaluation result according to the calculation result.
In one implementation, the block link point device calculates the random number and the first random seed to obtain a fourth numerical value; calculating the random number and the second random seed to obtain a fifth numerical value; and when the fourth numerical value is larger than the fifth numerical value, generating a priority evaluation result, wherein the priority evaluation result is used for indicating that the priority of the first client side is lower than that of the second client side.
assume that the second predetermined rule is: the priority of the client corresponding to the value with the fourth numerical value and the value with the fifth numerical value are lower. Specifically, the block link point device subtracts the fourth numerical value from the fifth numerical value, and when the obtained result is a positive number, it indicates that the fourth numerical value is greater than the fifth numerical value, and then the block link point device may determine that the priority of the first client is lower than that of the second client. That is, the first random seed differs from the random number by a greater amount than the second random seed. The above description is embodied on the coordinate axis, that is, the position of the first random seed on the coordinate axis is farther from the random number than the position of the second random seed on the coordinate axis.
for example, in a two-player game scenario, if the first random seed of the first betting party is 7 and the second random seed of the second betting party is 10, the random number is 13, the fourth value is 6, the fifth value is 3, and it is known that the fourth value 6 is greater than the fifth value 3. According to the second preset rule, the priority of the first client corresponding to the fourth numerical value is lower than the priority of the second client corresponding to the fifth numerical value. Is embodied on a coordinate axis, that is, means that the first random number is at a coordinate position farther from the random number.
It should be noted that the foregoing example is only used to illustrate that, when the difference value between the random number and the random seed of a certain party in a game is larger, the block-linked-point device determines that the priority of the client corresponding to the random seed is lower, and in other feasible implementation manners, the block-linked-point device may also determine that the priority of the client corresponding to the random seed is higher when the difference value between the random number and the random seed of the certain party in the game is larger, which is not limited in this embodiment of the present invention.
therefore, by comparing the difference value between the random number and the random seed, the random seed which is closer to the random number in the first random seed and the second random seed can be obtained, and the priority of the client corresponding to the random seed is judged to be higher, so that the priority judgment result can be based on the priority judgment result.
Step S413: and the block chain node equipment sends the priority evaluation result to the first client and the second client.
Specifically, the execution process of step S409 may refer to step S208 in fig. 2, which is not described herein again.
Therefore, by implementing the embodiment of the invention, the block link point device compares the fourth numerical value generated by the random number and the first random seed with the fifth numerical value generated by the random number and the second random seed to obtain the difference value between the fourth numerical value and the fifth numerical value, obtains the priority evaluation result according to the difference value, and sends the priority evaluation result to the first client and the second client. Based on the second preset rule, the priority levels of the first client and the second client can be obtained, and the priority evaluation result can be based.
