It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The resource allocation method based on the intelligent contract provided by the present application may be applied to an application environment shown in fig. 1, where fig. 1 is an application environment diagram of the resource allocation method based on the intelligent contract in an embodiment, the application environment may include a block-link point device 110, a resource allocation server 120, and a target terminal 130, the block-link point device 110 may communicate with the resource allocation server 120 and the target terminal 130 through a network, the resource allocation server 120 may also communicate with the target terminal 130 through the network, and the block-link point device 110, the resource allocation server 120, and the target terminal 130 may also be connected to the same block chain.
Specifically, the block link point device 110 obtains a resource allocation instruction, and executes a corresponding intelligent contract according to the resource allocation instruction, so as to obtain a resource allocation amount output by the intelligent contract and account information corresponding to the resource allocation amount; the smart contract may be pre-deployed on a block chain where the block-link point device 110 is located, and may be executed by the block-link point device 110. The intelligent contract is mainly used for determining a resource allocation amount and account information according to a resource allocation instruction received by the blockchain device 110, where the account information may include terminal identification information and blockchain account identification information. Then, the block-link point device 110 may send the obtained resource allocation amount and account information to the resource allocation server 120, the resource allocation server 120 may generate corresponding first resource allocation credential information according to the account information, and feed back the first resource allocation credential information to the block-link point device 110, the block-link point device 110 receives the first resource allocation credential information corresponding to the account information sent by the resource allocation server 120 and sends the first resource allocation credential information to the target terminal 130 corresponding to the terminal identification information, and the target terminal 130 sends second resource allocation credential information to the resource allocation server 120, so that when the second resource allocation credential information matches the first resource allocation credential information, the resource allocation server 120 allocates the resource corresponding to the resource allocation amount to a target block chain account, where the target block chain account is a block chain account corresponding to the block chain account identification information, so that after receiving the resource allocation instruction, the corresponding resource is allocated to the corresponding block chain account.
The block-link node device 110 and the target terminal 130 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the resource allocation server 120 may be implemented by an independent server or a server cluster composed of a plurality of servers.
In an embodiment, as shown in fig. 2, fig. 2 is a flowchart illustrating a resource allocation method based on a smart contract in an embodiment, which is described by taking the method as an example for being applied to the block-linked node device 110 in fig. 1, and includes the following steps:
in step S201, a resource allocation instruction is acquired.
In this step, the blockchain link point device 110 may obtain a resource allocation instruction, which may be used to transfer the corresponding resource to some accounts of the blockchain. The resource allocation instruction may be a resource allocation instruction triggered when a certain condition is met, taking a commodity transaction scenario as an example, when a commodity is traded (that is, a transaction event is generated), transaction information corresponding to a barcode of the commodity may be acquired by a barcode scanning gun of a supermarket, the transaction information may be recorded by a cashier system, and the block link node device 110 may generate the resource allocation instruction according to the transaction information after detecting that the transaction event is triggered. The transaction information may also be synchronously uploaded to the blockchain for storage after being acquired by the blockchain node device 110, so as to implement resource allocation traceability. In addition to triggering generation of a resource allocation instruction in the form of detection of an associated specific event (such as the above-mentioned transaction event), the resource allocation instruction may also be triggered to be generated at a specific time, such as (each of 8 am, 20 pm, and 00 pm triggers a resource allocation instruction).
Step S202, executing the corresponding intelligent contract according to the resource allocation instruction, and acquiring the resource allocation amount output by the intelligent contract and the account information corresponding to the resource allocation amount.
In this step, after acquiring the resource allocation command, the block link point device 110 may execute the corresponding intelligent contract according to the resource allocation command. The intelligent contracts may be pre-deployed in the blockchain and automatically executed on the blockchain node device 110, and the intelligent contracts deployed in the blockchain may include multiple intelligent contracts, where the intelligent contracts are executed when different resource allocation instructions are received and correspond to different resource allocation instructions. Taking a commodity transaction scenario as an example, different commodities can generate different transaction information when being transacted, and the block link node device 110 can generate corresponding resource allocation instructions according to the different transaction information, so as to execute different intelligent contracts according to the different resource allocation instructions. Specifically, the intelligent contract is mainly used for determining the resource allocation amount and the account information according to the resource allocation instruction, that is, for determining different allocation proportions and account information corresponding to the different allocation proportions according to the specific resource allocation instruction. The account information may include terminal identification information and blockchain account identification information, where the terminal identification information is used to identify the target terminal 130 shown in fig. 1, and the blockchain account identification information is used to identify a corresponding account on the blockchain.
Step S203, sending the resource allocation amount and the account information to a resource allocation server;
in this step, the blockchain link point device 110 needs to send the resource allocation amount and the account information (including the blockchain account information and the terminal identification information) to the resource allocation server 120. After receiving the resource allocation amount and the account information, the resource allocation server 120 may divide the stored resources to be allocated according to the resource allocation amount, and obtain the resources corresponding to the resource allocation amount. Meanwhile, the resource allocation server 120 further generates first resource allocation credential information according to the terminal identification information in the account information, where the first resource allocation credential information is mainly used to verify the identity of the target terminal 130, so as to verify that the user requesting resource allocation through the target terminal 130 is the same user as the blockchain account corresponding to the blockchain account identification information, and in a specific implementation, the first resource allocation credential information may be a short message credential code, question and answer verification information, and the like.
Step S204, receiving first resource allocation credential information corresponding to the account information sent by the resource allocation server.
The block link node device 110 receives the first resource allocation credential information corresponding to the account information fed back by the resource allocation server 120.
Step S205, sending the first resource allocation credential information to the target terminal corresponding to the terminal identification information.
In this step, after receiving the first resource allocation credential information, the blockchain node device 110 sends the first resource allocation credential information to the target terminal 130 corresponding to the terminal identification information, so that the target terminal 130 may generate corresponding second resource allocation credential information according to the first resource allocation credential information, and send the second resource allocation credential information to the resource allocation server 120, so as to request the resource allocation server 120 to send the corresponding resource to the target blockchain account. Specifically, when the first resource allocation credential information matches the second resource allocation credential information, the resource allocation server 120 may determine that the user requesting resource allocation through the target terminal 130 is the same user as the blockchain account corresponding to the blockchain account identification information, so that the resource corresponding to the resource allocation amount may be allocated to the target blockchain account, where the target blockchain account is the blockchain account corresponding to the blockchain account identification information, and complete the process of allocating the resource in a specific proportion to the corresponding blockchain account.
According to the resource allocation method based on the intelligent contract, after receiving a resource allocation instruction, a block link point device can execute a corresponding intelligent contract and acquire a resource allocation amount and corresponding account information output by the intelligent contract, the intelligent contract is pre-deployed on the block link point device, so that the resource allocation amount and the account information corresponding to the resource allocation instruction can be ensured to be accurate and effective, then the block link node device sends the resource allocation amount and the account information to a resource allocation server, first resource allocation credential information corresponding to the account information and fed back by the resource allocation server is sent to a target terminal, the target terminal can send second resource allocation credential information to the resource allocation server, if the two pieces of resource allocation credential information are matched, the resource allocation server allocates resources corresponding to the resource allocation amount to a target block link account, accurate and effective execution of a resource allocation scheme is ensured by combining a block link technology and an intelligent contract, and the corresponding resources can be accurately allocated to the corresponding block link account by contrast matching of the credential information, and the reliability of resource allocation is improved.
In one embodiment, the method for allocating resources based on intelligent contracts may further include the following steps:
acquiring an initial intelligent contract set by an authorized blockchain account; and if the instruction number of the authorization instructions received by the block chain node point equipment is the same as the total number of the accounts of the authorized block chain accounts within the set time range, deploying the initial intelligent contract serving as an intelligent contract to the block chain node point equipment.
The embodiment can set the intelligent contracts deployed on the blockchain by authorizing the blockchain accounts. Specifically, the block-link point device 110 may obtain an initial intelligent contract set by an authorized block-chain account, the authorized block-chain accounts on the block chain may include multiple authorized blocks, the authorized account initiating the initial intelligent contract may be one of the authorized accounts, and the initial intelligent contract received by the block-link point device 110 cannot be deployed first and needs to wait for authorization verification of each authorized block-chain account. The blockchain node device 110 may wait for an authorization instruction of each authorized blockchain account for the initial intelligent contract within a set time range. Each authorized block chain account can generate an authorization instruction for an initial intelligent contract and send the authorization instruction to the block chain node device 110, the block chain node device 110 receives the authorization instruction sent by each authorized block chain account within a set time range, counts the instruction number of the received authorization instruction, and if the instruction number is the same as the total number of accounts with which the account is blocked by the authorized library, deploys the initial intelligent contract as an intelligent contract on the block chain node device 110, and waits for the resource allocation instruction to be automatically triggered and executed. When the intelligent contract is deployed, authorization verification of each authorization blockchain account is required, so that the reliability of resource allocation can be further improved through the intelligent contract determined in the form.
In one embodiment, the step of obtaining the initial intelligent contract set by the authorized blockchain account may further include:
determining a candidate resource allocation scheme selected by an authorized blockchain account from a plurality of base resource allocation schemes corresponding to resources to be allocated; acquiring scheme correction information of the candidate resource allocation scheme by the authorized blockchain account; the scheme correction information is set by the authorized block chain account according to the resource allocation scene of the resource to be allocated; correcting the candidate resource allocation scheme according to the scheme correction information to obtain an initial intelligent contract; the initial intelligent contract comprises the resource allocation amount of the resource to be allocated and account information corresponding to the resource allocation amount.
The embodiment mainly provides a mode for generating the initial intelligent contract. In this embodiment, the blockchain node device 110 may first determine a candidate resource allocation scheme selected from a plurality of basic resource allocation schemes corresponding to resources to be allocated by the authorized blockchain account. The multiple basic resource allocation schemes for the resources to be allocated may be provided to each authorized blockchain account in advance, so that the authorized blockchain accounts may select one of the multiple basic resource allocation schemes as a candidate resource allocation scheme, thereby improving the efficiency of generating the initial intelligent contract, and after determining the candidate resource allocation scheme, the blockchain node device 110 may further obtain scheme modification information of the authorized blockchain accounts on the candidate resource allocation scheme, where the scheme modification information may be set by the authorized blockchain accounts according to a resource allocation scenario of the resources to be allocated, that is, a scheme modification function may be provided for the authorized blockchain accounts, so that the authorized blockchain accounts may be modified based on the candidate resource allocation scheme, and there is no need to reformulate a resource allocation scheme when the scheme does not meet actual requirements, so as to improve the efficiency of generating the intelligent contract. Then, the block-node device 110 may modify the candidate resource allocation scheme according to the scheme modification information, and further use the modified candidate resource allocation scheme as the initial intelligent contract.
In one embodiment, the executing the corresponding intelligent contract according to the resource allocation instruction in step S202 may include:
and determining the corresponding contract execution time according to the resource allocation instruction, and executing the intelligent contract if the current time is the same as the contract execution time.
In this embodiment, after receiving the resource allocation command, the block link point device 110 may determine a corresponding contract execution time according to the resource allocation command. Wherein, the contract execution time may be preset, for example, for all resource allocation instructions set to 8 m.m. or 20 m.m. 00, then if the current time is 8 m.m. or 20 m.m. 00; in addition, the contract execution time can be set according to different resource allocation instructions, so that corresponding intelligent contracts can be executed at different times, and the resource allocation is more flexible.
In one embodiment, the sending of the first resource allocation credential information to the target terminal corresponding to the terminal identification information in step S205 may be further configured to: the target terminal carries out digital signature on the first resource allocation certificate information by using a private key of the target block chain account to obtain second resource allocation certificate information and sends the second resource allocation certificate information to the resource allocation server; the second resource allocation credential information may be used for the resource allocation server to determine whether the second resource allocation credential information matches the first resource allocation credential by using the public key of the target block link account.
In this embodiment, after the block chain node device 110 sends the first resource allocation credential information to the target terminal 130, the target terminal 130 needs to perform a digital signature on the first resource allocation credential information by using a private key of the target block chain account, so as to further ensure that the user corresponding to the target terminal 130 and the user corresponding to the target block chain account belong to the same user, and ensure reliability of resource allocation. Then, the target terminal 130 needs to send the second resource allocation credential information obtained by digitally signing the first resource allocation credential information with the private key of the target block chain account to the resource allocation server 120, the resource allocation server 120 may determine whether the second resource allocation credential information matches the first resource allocation credential with the public key of the target block chain account, if the second resource allocation credential information matches the first resource allocation credential, the corresponding resource may be allocated to the target block chain account, and if the second resource allocation credential information does not match the first resource allocation credential, the resource may not be allocated to the target block chain account.
In some further embodiments, the first resource allocation credential information may include questioning information associated with resource attributes of the resource; the sending of the first resource allocation credential information to the target terminal corresponding to the terminal identification information in step S205 may be further configured to: the target terminal obtains answer information corresponding to the question information, obtains second resource allocation certificate information according to the answer information, and sends the second resource allocation certificate information to the resource allocation server, so that the resource allocation server judges whether the second resource allocation certificate information is matched with the first resource allocation certificate or not according to the answer information and the question information.
The embodiment mainly provides a mode of information question answering associated with the resource attribute so as to ensure the reliability of resource allocation. Specifically, the first resource allocation credential information generated by the resource allocation server 120 may include question information associated with a resource attribute of the resource, for example, question information associated with a resource attribute such as a resource size and a resource type of the resource, and the resource allocation server 120 may use the question information as the first resource allocation credential information. Then, the blockchain link point device 110 sends the first resource allocation credential information to the target terminal 130, the user of the target terminal 130 can answer the question information, the target terminal 130 can obtain the answer information of the question information from the user, and send the answer information as second resource allocation credential information to the resource allocation server 120, the resource allocation server 120 can compare the standard answer corresponding to the question information with the answer information, so as to determine whether the second resource allocation credential information matches the first resource allocation credential, if the answer information is the same as the standard answer, the second resource allocation credential information may be considered to match the first resource allocation credential, and the resource allocation server 120 allocates the corresponding resource to the target blockchain account, and if not, the resource allocation server 120 may not allocate the resource to the target blockchain account.
In an embodiment, the intelligent contract may be further configured to determine a corresponding resource allocation time limit according to the resource allocation instruction; the resource allocation method based on the intelligent contract further comprises the following steps:
acquiring resource allocation time limit output by an intelligent contract; and sending the resource allocation time limit to a resource allocation server.
In this embodiment, the resource allocation time limit may be preset on the intelligent contract, and different resource allocation instructions may correspond to different resource allocation time limits. The resource allocation time limit is used to indicate that, if the resource allocation server receives the second resource allocation credential information sent by the target terminal 130 within the resource allocation time limit, the resource may be allocated to the target blockchain account when the second resource allocation credential information matches the first resource allocation credential information. The resource allocation time limit may be further configured to indicate that, if the resource allocation server 130 receives the second resource allocation credential information outside the resource allocation time limit, the resource allocation server 130 may set the second resource allocation credential information as invalid credential information, and in this case, since the second resource allocation information is the invalid credential information, even though the second resource allocation information and the first resource allocation information may be matched with each other, the resource allocation server 130 may not allocate the resource to the target block chain account since the resource allocation time limit specified by the smart contract is exceeded, so as to improve the reliability of resource allocation from the viewpoint of limiting the resource extraction time.
The following describes the application of the above-mentioned resource allocation method based on intelligent contracts to online diversity scenarios. The method comprises the following steps of dividing profits into various interest relevant parties in real time after a transaction is completed, and applying a block chain to combine intelligent contracts, wherein resources can be reliably and timely distributed to various block chain accounts corresponding to the interest relevant parties, as shown in fig. 3, fig. 3 is a flow diagram of a resource distribution method of an application example based on the intelligent contracts, and the main idea of the application example is to adopt the intelligent contracts as a supporting technology, one of the characteristics of the intelligent contracts is to require to compile rules for defining the intelligent contracts before application, a dividing and lubricating mechanism is defined in the intelligent contracts, and the dividing and lubricating mechanism can be actually adjusted according to application scenes, but mainly comprises a fixed proportion distribution rule, a step-type distribution rule and an accumulative distribution rule.
The method mainly comprises the following steps:
step s1, an intelligent contract for the divided moistening is created. The intelligent contract comprises basic functions, such as functions of inquiring, calling, transferring and the like.
And step s2, setting the execution condition of the intelligent contract. Namely, the condition setting triggering the execution of the intelligent contract, including event triggering (after each transaction is completed), time triggering (each execution of 8 am and 00 pm and 20 pm every day).
And step s3, setting an execution process of the intelligent contract. When the intelligent contract is triggered to be executed, acquiring input values (transaction amount, transaction commodity type, price and quantity qualification, obtained according to commodity types, and the like) of one or more transactions, acquiring a run-out rule, acquiring right-of-interest information (account), and executing profit distribution, wherein the run-out rule can be as follows:
1. and (3) fixed proportion distribution: the profit that right beneficiary A can divide = (total transaction amount-total cost-total tax amount) × A is corresponding profit proportion, which can be expressed by a formula:
total profit P = revenue-cost-tcx
P A ＝P×ratio A
If a total of n beneficiaries, their profit totals no more than 100%, i.e. they share
Figure BDA0002353235310000121
The reason that it may be less than 100% is that a portion of the net profit may be cycled into business, development, or as a pool of incentives, etc., based on the negotiation of the rights beneficiary.
2. Stepwise distribution, can be

Or the following steps:

According to the profit allotment C that the right beneficiary A (in the current year or month) has accumulated to gain A And (4) performing calculation.

Wherein the percentage and the interval of 2 and 3 can be adjusted according to the actual scene.
And step s4, the rightful persons apply the intelligent contract after passing the scheme. In principle, once the intelligent contract is compiled and run, it is troublesome to change the function, and a new intelligent contract is generally established after the intelligent contract is cancelled.
