Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
In order to more clearly introduce the technical solutions provided by the embodiments of the present application, an application scenario of the embodiments of the present application is first introduced.
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, tamper resistance, anonymity, traceability and the like. Blockchain technology is of great importance for supply chain management: the supply chain operation generally relates to the cooperation among a plurality of interest parties, the monitored and traced information is often lost, and the block chain information is difficult to tamper, so that the anti-counterfeiting tracing of the supply chain is facilitated; in the block chain, as the data information stored by all the nodes is the same, the information asymmetry can be effectively eliminated, and the 'bullwhip effect' of the supply chain is weakened; by effectively applying the block chain technology, the information among all the nodes is synchronously updated, so that the response speed of the supply chain is probably compressed to the shortest, and the benefit of information flow is favorably realized; the intelligent contract of the block chain is operated, so that the related labor input can be reduced; the block chain operation does not need the participation of an intermediary, so that the trust cost can be reduced.
Based on the blockchain network, a supply chain may be built. The blockchain network comprises a plurality of nodes, and when the blockchain network is applied to a supply chain, one enterprise can be provided with one enterprise node, or a plurality of nodes can be provided with one common enterprise node. For the way that one enterprise node is set for one enterprise, it can be understood that each enterprise deploys a respective corresponding node. A common enterprise node is arranged for a plurality of nodes, and the common enterprise node can be deployed in main enterprises, auxiliary organizations and supervision organizations of a supply chain, such as core enterprises, suppliers, manufacturers, distributors, financial institutions, insurance organizations, government supervision departments and the like. When the enterprise information verification system is built, each enterprise is added into the block chain network to be registered, the supply chain block chain network verifies the enterprise information, and after the verification is passed, a trusted certificate can be issued to the enterprise to grant related authority. After the enterprise registration is successful, deploying corresponding blockchain nodes of the enterprise, installing blockchain basic services, configuring information such as node access information, node access authority, a data channel where the node is located and the like, and adding the node into a blockchain network, namely, synchronizing related blockchain data and account book data.
In addition, in the supply chain network, a certification account is also set, and the certification account can be a certification wallet similar to a virtual account of an enterprise. The voucher wallet stores the voucher information of the user (enterprise), including a voucher address (similar to a bank card account number), a private key (similar to a bank card password), and blockchain transaction information. The wallet form in the embodiment of the application is a cold wallet, the private key of the wallet is held in the hands of the user (enterprise) and is stored offline, the user can store the general certificate as the cold wallet by using an offline electronic device (such as a mobile phone), and the wallet has the property of no contact with the internet, so that the possibility of hacking can be greatly reduced. In consideration of the limited resources of general enterprise users, the embodiment of the application adopts the light-node wallet which depends on other full nodes in the blockchain network, only synchronizes transaction data related to the light-node wallet, not only can decentralization be realized, but also the problem that synchronization of all blockchain data occupies a large memory can be avoided.
Based on the above application scenario, please refer to fig. 1, where fig. 1 is a method for providing supply chain credential issuance in an embodiment of the present application, and is applied to an enterprise node, where the enterprise node may correspond to one enterprise or multiple enterprises in a supply chain, where the method includes:
step 101: and acquiring effective behavior information of the enterprise.
Step 102: and performing effective behavior evaluation according to the effective behavior information, and determining the corresponding pass-certificate quantity of the effective behavior based on the result of the effective behavior evaluation and a preset pass-certificate issuing rule.
Step 103: and changing the evidence-passing account data of the enterprise according to the evidence-passing quantity.
Compared with the prior art, the method for providing the supply chain general certificate associates the effective behaviors with the general certificate quantity, and only when the enterprise generates the effective behaviors, the general certificate of the corresponding quantity can be obtained. On one hand, even if the enterprise swipes the list maliciously, the corresponding transaction information may not be enabled to be an effective behavior, so that the situation is avoided to a certain extent, and the management of the transaction in the supply chain is facilitated; on the other hand, the mode that the effective action is associated with the number of the certificates which are communicated is adopted, the enterprise does not necessarily depend on the transaction number or the transaction amount to obtain the certificates which are communicated, so that the transaction enthusiasm of the enterprise is improved, the quality of the transaction action in the supply chain can also be improved, the management of the transaction in the supply chain is further facilitated, and the operation efficiency of the supply chain is further improved.
In step 101, on the supply chain, the effective behavior of the enterprise includes, but is not limited to: data sharing, order fulfillment, alliance pull, supervision mutual evaluation, etc. Then the corresponding valid behavior information may include: behavior information, namely which effective behavior is; data related to valid behavior such as data sharing volume, order achievement volume, etc. In addition, in step 101, the enterprise node may obtain the valid behavior information by obtaining from the blockchain network, because each enterprise in the supply chain may uplink the corresponding information after completing the valid behavior, so that the enterprise node may obtain the information from the blockchain. From another perspective, it is understood that an enterprise links effective behavior information through enterprise nodes, so that the enterprise nodes can also store the effective behavior information, but for convenience of management, the effective behavior information is linked uniformly, so that on one hand, the safety and the non-tamper property of the information are ensured, and on the other hand, the issuing of the certificate is facilitated.
Further, after obtaining the effective behavior information, the enterprise node may execute step 102, that is, perform effective behavior evaluation, and determine a corresponding number of passes for the effective behavior. In the supply chain, each enterprise node has installed on it a basic service of the blockchain, such as an intelligent contract, so an optional implementation of step 102: the intelligent contract in the block chain network comprises a behavior evaluation model and a evidence passing model; performing effective behavior evaluation according to the effective behavior information through a behavior evaluation model to obtain a contribution value corresponding to the effective behavior; determining the number of the certificates corresponding to the effective behaviors based on the contribution value and the relation between the preset contribution value and the total amount of the certificates issued through a certificate passing model; the total amount of the certificates issued is the total amount of the certificates in the supply chain in a preset period.
In this embodiment, two processes are involved, namely, calculating the contribution value through the behavior assessment model and calculating the number of certificates of the certificate of. It should be understood that the respective processes involved in the behavior evaluation model and the evidence-based model may be implemented by a plurality of intelligent contracts, that is, more than one intelligent contract may be included in the block chain, and each intelligent contract may have its own task, for example, one intelligent contract is used for evaluating the effective behavior, another intelligent contract is used for calculating the contribution value according to the evaluation result, and the like, and is not limited herein.
For calculating the contribution value, an optional implementation: determining a behavior quantization value of the effective behavior according to the effective behavior information; and calculating a contribution value corresponding to the effective behavior according to the behavior quantization value and a weight value of a preset behavior quantization value.
For the behavior evaluation model, the behavior evaluation model measures the value of the behavior of the enterprise according to the difference of the role and the effective behavior of the enterprise, and then records and accumulates the value in the form of contribution value. Scientifically measures the user behavior value and can provide effective Contribution Proof (PoC) for the issuing of the certificate of correspondence. The evaluation model has three essential elements: role(s), quantification of behavior (x), contribution value (y). Then a certain business siThe contribution value y obtainable for the behavior of (a) can be calculated as:
TABLE 1
For the certification model, the total input amount of the digital certification is based on the actual capacity, and a block chain technology is adopted to construct a supply chain certification incentive mechanism, so that the contribution degree and the digital certification of each pen are guaranteed, and the source and distribution can be traced and cannot be falsified. The certification model requires the design of a perfect distribution total (a), distribution rules, value anchoring and consumption mechanism.
The total issuance amount is the total number of the certificates issued in the supply chain within a preset period, which may be one year or one month, and the total issuance amount per year may be calculated by taking the preset period as one year, for example. An alternative embodiment: the total issue amount (a) includes an initial issue amount (X) and an increase amount. The volume of increase of hair is determined whether the increase of hair is needed after N years according to the operation condition, and the volume of increase of hair (R) is what. The annual issue volume (T) can be calculated as: t isi＝X(1+R)i1,2,3,.., n, the total amount of n years released (a) can be calculated as: a ═ T1+T2+...+Tn。
Further, for the issuing rule, since the total amount of the certificates is limited, the certificates are distributed fairly and fairly according to the contribution of the subject enterprise, and the distribution scheme is the issuing rule. The issuance rules are essentially representative of the relationship between contribution values and issuance totals. Continuing with the example of the preset period as a year, the number of certificates (t) that can be obtained by each subject enterprise per day can be calculated as:
where y is the contribution value and T is the annual release volume.
In the embodiment of the application, after the contribution value corresponding to the effective behavior is obtained, the corresponding certificate passing number of the effective behavior is determined according to the contribution value and the relation between the preset contribution value and the certificate passing total issuing amount, and the certificate passing total issuing amount is the total certificate passing number in the supply chain in the preset period. When effective behavior evaluation is carried out, the contribution value is calculated based on the behavior quantization value and the corresponding weight value, so that the calculated contribution value is more reasonable, and further, the evidence is reasonably distributed according to the contribution value.
Further, after determining the number of certificates, step 103 may be executed to change the certificate account data of the enterprise according to the number of certificates. In step 103, changing the data of the passport account may be understood as issuing passphrases, for example, if the original number of passphrases in the passport account is 0 and the determined number of passphrases in step 102 is 10, the number of passphrases is changed to 10, and the issuing of passphrases is completed. Taking the passport wallet as an example, assuming that the evaluated effective behavior is from the first enterprise, and the determined number of passports is 10, the number of passports in the passport wallet of the first enterprise may be changed, and for the passport wallet of the first enterprise, there may be original assets, for example, 1 passport, and then the number of passports in the passport wallet may be correspondingly increased by 10. In short, the evidence-based wallet is a virtual account, which can manage assets and also can make payment, and so on, so that various feasible asset management methods can be applied to the technical scheme of the embodiment of the application, and are not limited herein.
In the embodiment of the present application, after the issuance of the pass certificate is completed, the pass certificate application may also be performed, and for the pass certificate application, the embodiment of the present application provides three optional implementation manners, which are introduced separately.
First alternative embodiment: receiving a certificate exchange request initiated by an enterprise; the certificate passing exchange request comprises the privilege to be exchanged; and changing the certificate-passing account data of the enterprise according to the certificate-passing exchange request, and destroying the certificate-passing corresponding to the certificate-passing exchange request.
In such embodiments, the pass is used to redeem privileges that may facilitate more transactions by the enterprise, promoting operational efficiency throughout the supply chain. The privilege may be, for example: obtaining price advantage, increasing order quantity, putting directional advertisement, etc. In addition, the voucher redemption request initiated by the enterprise can be initiated from a voucher wallet or directly at the enterprise node. Further, when the privilege is exchanged, a certificate-passing wallet is taken as an example. The changed account data is similar to that of the certificate issuing, and if the number of the privileges in the original certificate wallet is 0 and 3 privileges are exchanged, the three privileges are correspondingly added to the certificate wallet. The privileges here are similar to coupons or benefits provided by the Taobao merchant, etc. Furthermore, after the certificate is used, the certificate has no value any more, and the used certificate is directly destroyed in order to facilitate certificate management of the supply chain.
For the use of privileges, assuming the redeemed privilege is to deliver targeted advertisements, the business may publish the targeted advertisements on the supply chain and inform the various businesses in the supply chain. Assuming that the redemption privilege is to obtain a price advantage, the business may sell a good on the supply chain at an advantageous price determined in the supply chain and advise the business and the buyer in the supply chain. Other privileges, similar to the exemplary privileges, may be used in various specific contexts, such as during or prior to a transaction in the supply chain.
In the embodiment of the application, the certificate of correspondence can be used for enterprise redemption privileges, and corresponding certificate of correspondence is destroyed, so that the flow of the certificate of correspondence in the supply chain is promoted, and the operation efficiency of the supply chain is further improved.
Second alternative embodiment: receiving a certificate-based repurchase request initiated by a third party; the voucher buyback request comprises the number of vouchers to be buyback and buyback funds of the vouchers to be buyback; sending the voucher buyback request to a voucher wallet; and when a confirmation buyback request initiated by the enterprise is received, the voucher account data of the enterprise is changed according to the voucher buyback request, and the voucher corresponding to the voucher buyback request is destroyed.
In such embodiments, after receiving the voucher repurchase request, the voucher repurchase request is synchronized to each enterprise in the blockchain, when the enterprise determines to sell the voucher, a confirmation repurchase request can be initiated, and the enterprise node then alters the fund data in the voucher account. Similarly, after the repurchase of the voucher is completed, the voucher is destroyed in order to facilitate the management of the voucher in the supply chain.
In this application embodiment, the third party can initiatively carry out the buyback of leading to the card to destroy the corresponding card that leads to, adjust the quantity of leading to the card in the supply chain, avoid leading to the piling up of card, improve the operation efficiency of supply chain.
Third embodiment: receiving a certificate clearing request initiated by an enterprise; the number of the certificates to be settled is included in the certificate passing settlement request; determining settlement fund information according to the number of the certificates to be settled, and sending a certificate clearing request and the settlement fund information to a third party; and changing the evidence-passing account data of the enterprise according to the settlement fund fed back by the third party and destroying the evidence-passing corresponding to the evidence-passing settlement request.
In such an embodiment, the enterprise may actively initiate a clearing request, which may be initiated at an enterprise node or via a clearing wallet (clearing account). Further, after receiving the request, determining settlement fund information (namely, how much fund can be settled) according to the number of the certificates to be settled, and then sending the settlement fund information to a third party, wherein the third party can directly feed back settlement funds after confirming that the funds are correct, and correspondingly, the enterprise node changes fund data in the certificate-passing account according to the settlement funds.
In the embodiment of the application, the enterprise can also initiatively settle the pass to the third party to obtain settlement funds and destroy the corresponding pass, so that the flow of the pass in the supply chain is promoted, and the operation efficiency of the supply chain is improved.
In addition to the three embodiments described above, the voucher can also be used to redeem raw materials, goods, etc. in the supply chain.
In addition, in the above three embodiments, regarding the value of the certificate, for example, what privileges a certificate can be exchanged, or how much money a certificate has, value anchoring can be performed through the certificate model in the foregoing embodiments. The value of the permit can determine whether the enterprise is willing to obtain the permit and use the permit, and further influences the operation efficiency of the supply chain, so a reasonable anchoring relation needs to be set, and the enterprise is attracted to earn the permit by using the means of fastest speed, lowest cost and highest efficiency. Thus, a supply chain fund may be established, the fund members comprising the supply chain subject enterprise, and the fund may correspond to the third party described in the previous embodiments, i.e., the third party is a platform on which the certified transaction may be conducted. The fund foundation sets up the RMB fund pool to support the exchange and the privilege of the general certificate, and the fund investment of each year (Q) is determined by the exchange amount of the last year (D), then the fund investment can be calculated as:
the anchoring relationship (e) of the certificate and the renminbi can be calculated as:based on this anchoring relationship, the fund pool may be allocated to different privileges for the enterprise to select and redeem. For example, an enterprise may obtain price advantage in the supply chain with digital certificates, increase the volume of orders, and place privileges for targeted advertising.
In the embodiment of the present application, it can be seen that, in combination with the issuance of the certificate of pass and the application of the certificate of pass, the function of the certificate of pass wallet (certificate of pass account) of the enterprise: (1) as a payment method: in the supply chain block chain ecology in the embodiment of the application, the certificates can be exchanged for raw materials, commodities, privileges and the like on the supply chain, and the certificate wallet is an entrance of certificate payment. (2) As an asset management platform: for the user, the function of obtaining the evidence of the currency assets, inquiring the transaction records, and extending the functions of obtaining the evidence of the currency, managing the finance and the like can be realized in the currency wallet system. (3) As a negotiation point of transaction: enterprises on the upstream and downstream of the supply chain can negotiate and cooperate in the voucher wallet system and directly use voucher transactions.
Furthermore, it can be seen that the management mode of the supply chain adopted by the embodiment of the application guides the effective behavior of the enterprise based on the incentive to the enterprise, and can promote the benign operation and development of the supply chain. In addition, the block chain technology is adopted to construct the certification system, so that the contribution degree and the number of each item are certified, the source and the distribution can be traced and cannot be falsified, and the credibility, the safety and the fairness of the supply chain are ensured.
With reference to the introduction of the foregoing embodiment and referring to fig. 2, a schematic diagram of a supply chain operation mode provided in the embodiment of the present application is shown in fig. 2, where the behavior evaluation model determines effective behaviors of an enterprise by analyzing roles and interest demands of the enterprise, and after chaining the behaviors of the enterprise, the enterprise node calls the behavior evaluation model to measure the value of the behaviors. And then carrying out the corresponding certificate issuing according to the value measured by the certificate issuing total amount and the certificate issuing rule which are designed by the certificate issuing model, wherein the data certificate storing means the contribution value obtained by calculation. Further, after the enterprise obtains the certificate of correspondence, the enterprise node calls the certificate of correspondence model to exchange the certificate of correspondence for the enterprise according to a value anchoring and destroying mechanism. Of course, the illustration in fig. 2 only relates to some embodiments in the foregoing embodiments, and other embodiments are also applicable to this operation mode.
