The problem of excessive consumption of hardware resources exists when the PoW consensus algorithm is used for executing consensus, specifically: the higher the hardware configuration of the consensus node is, the maximum probability of calculating the random number is, that is, the higher the probability of being able to obtain the accounting right is, and in order to compete for the accounting right, the hardware configuration of each consensus node is configured to be higher and higher. The fairness problem exists when using PoS consensus algorithm to execute consensus, which is specifically: the more the assets of the consensus nodes are distributed, the higher the probability of obtaining the accounting weight is, in other words, the less the assets of the consensus nodes are distributed, the lower the probability of obtaining the accounting weight is, and obviously, the fairness problem exists in determining the block link points for obtaining the accounting weight according to the quantity of the assets.

Before the technical solution of the embodiment of the present invention is explained in detail, a system architecture applied to the block chain accounting node method of the embodiment of the present invention is briefly explained.
Fig. 1 is a schematic diagram of a system architecture applied to a block chain accounting node selection method according to an embodiment of the present invention, where a plurality of block chain nodes may exist in a block chain network applied to an embodiment of the present invention, and fig. 1 illustrates 4 block chain nodes as an example, as shown in fig. 1, the system includes a block chain accounting system formed from a block chain node 101 to a block chain link point 104, a game terminal and a game server corresponding to the block chain node 101, a game terminal (not shown in fig. 1) corresponding to the block chain node 102, a game terminal (not shown in fig. 1) corresponding to the block chain node 103, and a game terminal (not shown in fig. 1) corresponding to the block chain node 104. The blockchain node 101 may be another terminal different from the game terminal, or may be the game terminal, and the game server may provide services for each game terminal.
Here, the specific process of building the system architecture may include the following steps:
step 1, building a block chain accounting system.
Specifically, at least two block chain nodes are deployed in a function peer-to-peer manner between different service bodies participating in a service to construct a block chain network; wherein, the block link point may be a client.
And 2, building a terminal system formed by the block chain link points and the game terminal.
Specifically, one blockchain node may correspond to one game terminal; the blockchain node may be another terminal different from the game terminal; or the game terminal.
And step 3, building a game system.
Specifically, one game server is deployed for a plurality of game terminals.
The built game server can be used for building game scenes, and the type of the game can be a game which cannot improve the game score by means of stacking computing power, but a game which determines the win or loss ranking by means of subjective behaviors of people, such as Virtual Reality (VR) racing games, archery masters, shadowless lamps and the like; the established game terminal can be used for a user to access a VR game, and the consensus node on the block chain network is initiated through the corresponding block chain link to carry out consensus on the game score ranking, so that the accounting node is determined; the established block chain accounting system can account for the generated transaction through the determined accounting node.
The implementation of the embodiments of the present invention will be described in detail below with reference to the attached drawings, which are provided for illustration purposes only and are not intended to limit the invention.
As shown in fig. 2, a detailed description is given of a block chain accounting node selection method according to an embodiment of the present invention, where the method of the embodiment is applied to a terminal side, and includes the following steps:
step 201: the first block link point obtains a current game achievement ranking. And the game result ranking is obtained after the game terminal corresponding to each block link point plays the game.
The current game achievement ranking can be the game achievement ranking generated by the game played after triggering one-time consensus; or may refer to a game achievement ranking that occurs during the time interval between two consensus.
After the system architecture is built, in an embodiment, the acquiring, by the first tile link point, a current game achievement ranking of the user includes: the first block chain node acquires the current game score ranking of the user from the game terminal; the game result ranking is sent to the game terminal by the game server.
The process of the game server determining the game achievement ranking may include the following two cases:
in the first case, when the transaction number recorded by any one of the block link points in the block chain network reaches one block, the game is triggered to start, that is, after the consensus is triggered, the game terminal users corresponding to the block link points start the game, and after the game is finished, the game server obtains the current game score ranking.
In the second case, after the last consensus, the game terminal user corresponding to each block link point starts playing, and when the transaction number recorded by any one block link point reaches one block, namely the consensus is triggered again, the game server obtains the current game score ranking.
Taking the system architecture shown in fig. 1 as an example, a process of obtaining a ranking of a current game achievement is described in detail, where the first block link point may specifically be the block link point 101 in fig. 1, and the process may specifically include:
before the consensus is triggered, after any block chain link point in the block chain accounting system generates a transaction, the corresponding block chain link point can broadcast the generated transaction to other block chain nodes, and meanwhile, original transaction information of an account book which is not recorded in the broadcast is acquired; acquiring an address of a payer, such as a public key address, based on the acquired original transaction information; and calculating whether the balance of the payer is enough to pay the transaction, if so, verifying the signature of each transaction to determine the authenticity of the transaction; when the number of transactions passing the verification reaches one block, the transactions can be packed to obtain a new packed block.
When the transaction quantity recorded by any block chain node in the block chain network reaches one block, triggering one consensus.
After the consensus is triggered, the game terminal users corresponding to the link points of each block can start the game; or, after the last consensus is finished, the game terminal user game corresponding to each block link point is started.
After the game starts, the corresponding block link points can send notification messages to the game server; the notification message is used for indicating the game server to send a preset game and game starting time to each game terminal; after receiving the notification message, the game server sends a preset game and game starting time to each game terminal; when the game starting time displayed on the display interfaces of the game terminals reaches, the corresponding users can participate in the preset game. The preset game can be VR racing game, Bow and arrow master and the like, and after the game is finished, the ranking of the current game achievements is generated.
And after the common identification is triggered again, the game server acquires and stores the game score ranking of each game terminal user. Specifically, when the preset game is a VR racing game and a terminal position is set in a VR racing game scene, the server may determine the game score ranking of each game terminal user in the sequence of reaching the terminal position; or counting the game duration of each game terminal user, and determining the game score ranking of each game terminal user according to the game duration. Here, the game server may determine and store the game result ranking rather than storing the game result ranking on the game terminal, thereby avoiding the occurrence of a game result user tampering with the game result.
After determining the game result ranking, the game server may send the game result ranking to the game terminal of the corresponding blockchain node 101; the game terminal corresponding to the blockchain node 101 may send the game result ranking to the blockchain node 101.
Step 202: broadcasting the game achievement ranking to at least one second blockchain node.
In order for the at least one second block link point to verify the game achievement ranking, the first block link point may broadcast the game achievement ranking to the at least one second block chain node.
The game achievement ranking may be synchronously recorded after the at least one second tile link point receives the game achievement ranking. Here, after the at least one second block link point synchronously records the game result ranking, the game result ranking is verified, the verification result is broadcast over the whole network, and the game result ranking cannot be tampered by each second block link point, so that the accuracy and fairness of consensus verification can be ensured.
Step 203: receiving a check result returned by the second block link point; and the verification result represents a result of verifying the received game result ranking by the second block link point.
Here, the at least one second block link point respectively verifies the received game result ranking, and the received game result ranking may be automatically compared by the at least one second block link point according to the game result recorded by the at least one second block link point, so as to complete verification and confirmation of the game result ranking.
Here, by commonly recognizing the game result ranking through the at least one second block link point, only the game result ranking needs to be compared, so that high hardware resources do not need to be configured for the at least one second block link point, and therefore, the hardware resources can be saved.
Step 204: judging whether the game score ranking is effective or not based on each returned check result; when determined to be valid, an accounting node is determined from the plurality of blockchain nodes based on the game score ranking.
When the first tile link point determines whether the game result ranking is valid, in an embodiment, the determining whether the game result ranking is valid based on each returned verification result includes: counting the number of verification results which represent passing of verification based on each returned verification result; judging whether the number is greater than or equal to a preset threshold value; determining that the game achievement ranking is valid when the number is determined to be greater than or equal to the preset threshold.
For example, the first block link point counts the total number of returned verification results and the number of verification results representing passing of verification; calculating the product of the total amount and a preset proportion to obtain the preset threshold; judging whether the number is greater than or equal to the preset threshold value; determining that the game achievement ranking is valid when the number is determined to be greater than or equal to the preset threshold. Wherein, the preset proportion can be 50%.
Here, the first block link point broadcasts the game result ranking of each round to each second block link node, and when more than 50% of the second block link points confirm that the game result ranking is valid, consensus is achieved, thereby preventing game terminal users from tampering with the game result, and effectively preventing cheating in games.
After the game achievement ranking is judged to be valid, an accounting node can be determined from the blockchain nodes according to the game achievement ranking. The method specifically comprises the following two conditions:
in the first case, the block link points with the game achievements ranked meeting the first preset condition are used as the accounting nodes.
In the second case, the accounting node is determined by utilizing the corresponding relation between the game result ranking and the probability.
When determining a billing node based on the first preset condition, in an embodiment, the determining a billing node from each blockchain node based on the game score ranking includes: determining the block chain nodes of which the game score ranking meets a first preset condition from all the block chain nodes based on the game score ranking; and taking the determined block link points as accounting nodes.
The block link point meeting the first preset condition may be a block link point corresponding to a game terminal user with a first game result rank. That is, the accounting right can be obtained by the block link point corresponding to the game champion and used as the accounting node. Here, the block link points corresponding to the game champions can acquire the accounting right, so that the potential of each game terminal user participating in the game can be stimulated, and the enthusiasm of each game terminal user participating in the game can be improved.
When determining a billing node by using the corresponding relationship between the game result ranking and the probability, in an embodiment, the determining a billing node from each blockchain node based on the game result ranking includes: ranking the game achievements as input data of an intelligent contract; the rule script of the intelligent contract is the corresponding relation between the rank and the probability of a preset game score; obtaining the identification of the block chain node based on the intelligent contract by utilizing the input data; and taking the block link point corresponding to the obtained identification as an accounting node.
The intelligent contract may refer to a program which is deployed in a blockchain network and is triggered to execute according to the corresponding relation between the game achievement rank and the probability.
Before executing the intelligent contract, a corresponding relationship between the game result ranking and the probability may be established in advance, and specifically, the corresponding relationship may be: if the game achievement ranking is the first name, the set probability can be 10%, and the probability for representing that the corresponding block link point is taken as the output node is 10%; if the game score is ranked as the second name, the set probability can be 8%, and the probability for representing that the corresponding block link point is taken as the output node is 8%; if the game score is ranked as the first name, the set probability can be 6%, and the probability for representing that the corresponding block link point is taken as the output node is 6%; and so on, and will not be described herein.
An intelligent contract component may also be deployed on the first block link point prior to executing the intelligent contract determination output block link point. When a preset condition is triggered, namely the game score ranking is determined to be effective, executing the intelligent contract through the intelligent contract component to obtain an output block link point; and returning the outputted block link point to the first block link node by the intelligent contract component.
Here, the block link point corresponding to the game terminal user with the low game result ranking has the possibility of obtaining the accounting right, because the probability of obtaining the accounting right is determined through the game result ranking, and the block link node for obtaining the accounting right is determined based on the intelligent contract. Obviously, the enthusiasm of the player with poor game level can be improved, meanwhile, the problem that the player who overloads the top of the ranking list of the game achievements for a long time continuously obtains the accounting right is avoided, and more players can be attracted.
The accounting node determined based on the first preset condition and the intelligent contract can acquire the accounting right for accounting the transaction.
After determining the billing node, in an embodiment, the method further comprises: the accounting node broadcasts the packed blocks to other block chain nodes; the block is used for verifying the other block chain link points to obtain a verification result, and broadcasting the verification result; receiving the verification results returned by the other block chain link points; the verification result represents the result of verifying the received block by the other block link points; judging whether the verification result meets a second preset condition or not; and when the second preset condition is met, adding the block into the block chain of the block.
The verification result meeting the second preset condition may be that the number of verification results representing that verification passes is greater than or equal to a preset number threshold. The block may be a data structure for recording transaction data and game score ranking data updated by the exchange within a period of time; the block body of the block is transaction data, and the block head of the block is shown in table 1.
Table 1 is a block header diagram of the block, as shown in table 1, including: the version number, the Hash value of the last block (block), and the Hash, the timestamp, the game name and the game score ranking formed by packaging the transaction data within the time from the generation of the last block to the generation of the new block.
TABLE 1
As can be seen from table 1, the packed block may be marked with a timestamp and a unique mark of the previous block, such as the last block hash value. After the consensus of each second block chain node in the block chain network is verified, the packed new block is added to the end of the block chain by the first block chain node to become a new block.
When the packed block is verified, the other block chain nodes can verify whether the transaction data in the block is consistent with the transaction record stored by the node, and return a verification result to the accounting node; the accounting node can judge whether the verification result of 51% of the block chain nodes is verified; when determined, the accounting node appends the packed block to the end of the block chain as a new block.
Here, if the game terminal users corresponding to the other block link points have any cheating behavior, the accounting node may determine that the verification result of no 51% of the block link nodes is verified, so that the accounting node directly discards the packed blocks, and thus the packed blocks cannot be recorded in the general ledger, and the game cost paid by the corresponding game terminal users is wasted. Obviously, the cheating risk of game terminal users corresponding to the remaining block link points can be reduced.
And after the accounting node adds the packed block to the tail of the block chain to become a new block, a game terminal user corresponding to the accounting node can obtain the fixed game reward and the fixed game reward is recorded by the accounting node. Thereafter, the respective game terminal user waits for the start of the next round of game play.
In one embodiment, before the accounting node broadcasts the packed blocks to the other blockchain nodes, the method further comprises: the accounting node acquires the unrecorded transaction; judging whether the unrecorded transaction amount is larger than or equal to a preset transaction threshold value; and when the transaction is determined to be greater than or equal to the preset transaction threshold, packaging the unrecorded transaction to obtain a block.
Wherein the unrecorded transactions may include transactions generated by the accounting node, and transactions that are not recorded into the ledger that are broadcast by the accounting node from other block link points.
Here, the process of block packing may specifically include: when the accounting node acquires the unrecorded transaction, the address of the payer, namely the public key address, can be acquired; judging whether the balance of the payer is enough to pay the transaction according to the address of the payer; when the surplus of the payer is determined to be enough to pay the transaction, verifying the signature of the unrecorded transaction to determine the authenticity of the transaction; when the verification is determined to pass, counting the transaction number passing the verification; and when the counted transaction quantity is greater than or equal to the preset transaction threshold value, packaging the transactions corresponding to the transaction quantity to obtain a block.
By adopting the technical scheme of the embodiment of the invention, in the process of determining the accounting node, only the game result ranking needs to be checked through each second block link point, when the game result ranking is effective, the accounting node is determined based on the effective game result ranking, obviously, the accounting node has no relation with the hardware configuration height of each second block link point, so that the hardware resource can be saved, and the accounting node can be determined.
In addition, an efficient and interesting consensus algorithm is provided by combining a blockchain technology and a game scene, specifically, through a competition scene provided by a game such as a VR racing game, participants of the game vote the ranking of game results, namely consensus verification, and when more than 50% of game participants vote, a billing node for obtaining a billing right is determined according to the ranking of the game results; the game terminal users corresponding to the accounting nodes obtain rewards, and the problems of large computing power and unfairness existing in the conventional consensus algorithm can be solved.
Based on the block chain accounting node selection method provided in each embodiment of the present application, the present application further provides a block chain accounting node selection device, where the device may be disposed on a terminal, as shown in fig. 3, and the device includes:
an obtaining unit 31, configured to obtain a current game score ranking from the first block link point; the game result ranking is obtained after the game terminal corresponding to each block link point plays a game;
a broadcasting unit 32, configured to broadcast the game achievement ranking to at least one second blockchain node;
a receiving unit 33, configured to receive a check result returned by the second block link point; the verification result represents a result of verifying the received game score ranking by the second block link point;
a determining unit 34, configured to determine whether the game result ranking is valid based on each returned verification result; when determined to be valid, an accounting node is determined from the plurality of blockchain nodes based on the game score ranking.
In an embodiment, the obtaining unit 31 is specifically configured to: the first block chain node acquires the current game score ranking of the user from the game terminal; the game result ranking is sent to the game terminal by the game server.
In an embodiment, the determining unit 34 is specifically configured to: counting the number of verification results which represent passing of verification based on each returned verification result; judging whether the number is greater than or equal to a preset threshold value; determining that the game achievement ranking is valid when the number is determined to be greater than or equal to the preset threshold.
For example, the first block link point counts the total number of returned verification results and the number of verification results representing passing of verification; calculating the product of the total amount and a preset proportion to obtain the preset threshold; judging whether the number is greater than or equal to the preset threshold value; determining that the game achievement ranking is valid when the number is determined to be greater than or equal to the preset threshold. Wherein, the preset proportion can be 50%.
Here, the first block link point broadcasts the game result ranking of each round to each second block link node, and when more than 50% of the second block link points confirm that the game result ranking is valid, consensus is achieved, thereby preventing game terminal users from tampering with the game result, and effectively preventing cheating in games.
In an embodiment, the determining unit 34 is specifically configured to: determining the block chain nodes of which the game score ranking meets a first preset condition from all the block chain nodes based on the game score ranking; and taking the determined block link points as accounting nodes.
In an embodiment, the determining unit 34 is specifically configured to: ranking the game achievements as input data of an intelligent contract; the rule script of the intelligent contract is the corresponding relation between the rank and the probability of a preset game score; obtaining the identification of the block chain node based on the intelligent contract by utilizing the input data; and taking the block link point corresponding to the obtained identification as an accounting node.
The accounting node determined based on the first preset condition and the intelligent contract can acquire the accounting right for accounting the transaction.
In one embodiment, the apparatus further comprises:
the block verification unit is used for broadcasting the packed blocks to other block chain nodes by the accounting node; the block is used for verifying the other block chain link points to obtain a verification result, and broadcasting the verification result; receiving the verification results returned by the other block chain link points; the verification result represents the result of verifying the received block by the other block link points; judging whether the verification result meets a second preset condition or not; and when the second preset condition is met, adding the block into the block chain of the block.
The verification result meeting the second preset condition may be that the number of verification results representing that verification passes is greater than or equal to a preset number threshold. The block may be a data structure for recording transaction data and game score ranking data updated by the exchange within a period of time; the block body of the block is transaction data.
When the packed block is verified, the other block chain nodes can verify whether the transaction data in the block is consistent with the transaction record stored by the node, and return a verification result to the accounting node; the accounting node can judge whether the verification result of 51% of the block chain nodes is verified; when determined, the accounting node appends the packed block to the end of the block chain as a new block.
Here, if the game terminal users corresponding to the other block link points have any cheating behavior, the accounting node may determine that the verification result of no 51% of the block link nodes is verified, so that the accounting node directly discards the packed blocks, and thus the packed blocks cannot be recorded in the general ledger, and the game cost paid by the corresponding game terminal users is wasted. Obviously, the cheating risk of game terminal users corresponding to the remaining block link points can be reduced.
And after the accounting node adds the packed block to the tail of the block chain to become a new block, a game terminal user corresponding to the accounting node can obtain the fixed game reward and the fixed game reward is recorded by the accounting node. Thereafter, the respective game terminal user waits for the start of the next round of game play.
