Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. 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 offline certification distributing method provided by the application can be applied to the application environment shown in fig. 1. Wherein, the blockchain node (hereinafter, referred to as node) 102 communicates with the server 104 (hereinafter, referred to as server 104) of the multi-currency/evidence-passing type blockchain system through the network. Specifically, a plurality of block link points 102 to be allocated (to be exchanged) for offline certification may exist in the block link system, when the server 104 receives an offline certification exchange application request, the server 104 responds to the request to obtain certification basic data, where the certification basic data includes current time certification circulation data, current held certification information of the block link nodes, and historical certification transaction records, and then determines whether the block link points satisfy a preset offline certification exchange condition according to the historical certification transaction records, and if so, determines offline certification allocation data of the block link nodes according to the certification basic data, where the offline certification allocation data includes a transfer ratio of offline certification to general certification and an initial amount of exchangeable offline certification, and when an initial amount of exchangeable offline certification of the block link nodes is obtained, obtains the transfer ratio of offline certification to general and the current held certification information according to the transfer ratio of offline certification to general and the initial amount of exchangeable offline certification, and confirming whether the common evidence of the block chain node is enough to exchange the offline evidence corresponding to the initial amount of the redeemable offline evidence, so as to determine the actual amount of the redeemable offline evidence, and then, redeeming and distributing the offline evidence according to the actual amount of the redeemable offline evidence. The blockchain node 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, an offline certification allocation method is provided, which is described by taking the method as an example applied to the server 104 in fig. 1, and includes the following steps:
step S200, obtaining the basic data of the certificate of pass, wherein the basic data of the certificate of pass comprises the current time certificate of pass circulation data, the current holding certificate of pass information of the block chain nodes and historical certificate of pass transaction records.
In practical application, the currently held certification information of a block chain node refers to the currently held certification related information of a block chain link point, which may be obtained when the block chain link point actively applies for offline certification, or obtained by analyzing according to the last online state information of the block chain link point stored locally. Specifically, the currently held pass information includes, but is not limited to, the currently held pass type, the pass amount, and the like. The historical certified transaction record of the blockchain node refers to historical transaction data of the blockchain node which transacts by using the certification, and the historical transaction record comprises the historical transaction record of using the offline certification and the historical transaction record of the common certification. The current time circulation data includes circulation number, circulation ratio, issue number, and the like of various types of negotiable instruments in the system at the current time.
And step S400, when the block chain link points are judged to meet the preset offline evidence-passing exchange conditions according to the historical evidence-passing transaction records, determining offline evidence-passing distribution data of the block chain nodes according to the evidence-passing basic data, wherein the offline evidence-passing distribution data comprise the exchange ratio of the offline evidence-passing and the common evidence-passing and the initial amount of exchangeable offline evidence-passing.
Due to the importance of offline evidence transfer, after the current held evidence transfer information of the block chain nodes and the historical evidence transfer transaction records of the block chain nodes are obtained, the current held evidence transfer information and the historical evidence transfer transaction records can be analyzed, and whether the current block chain nodes meet the conditions of offline evidence transfer or not is judged. Specifically, the step of judging whether the current block link point meets the criterion of offline certificate authority may be that the current block link point does not meet the preset offline certificate authority exchange condition when at least the following conditions are included, and the process is ended: the first item is that malignant transaction records exist in the historical evidence transaction records, wherein the malignant transaction records comprise that the number of times of using a node for one evidence in the transaction reaches at least 2 times, or in the transaction process, the node rewrites a block chain aiming at the block chain to replace the historical block records, and the malignant transaction records also comprise operation records of the node such as Sybil attack, DDoS attack (Distributed Denial of Service), embezzlement of other person identity information and the like in the transaction process; second, there is offline corroborative transaction data in the historical corroborative transaction record that is overdue and not cleared (i.e., transactions that have been offline corroborative transactions in the past period of time, but not online cleared in the time that online corroborative clearance is required). And if the node meets the exchange condition, determining offline evidence-passing distribution data of the block chain node according to the evidence-passing basic data, wherein the offline evidence-passing distribution data comprises the exchange ratio of the offline evidence-passing and the common evidence-passing and the initial amount of the exchangeable offline evidence-passing. The exchange ratio of the offline general certificate and the common general certificate is the exchange ratio of the offline general certificate and the common general certificate, and under a general condition, the default value of the exchange ratio of the system offline general certificate and the common general certificate is 1 offline general certificate: 1.2 common certificates, that is, 1.2 common certificates can be exchanged for one offline common certificate. In this embodiment, prior to redeeming the offline certification,
and step S600, confirming the actual amount of the exchangeable offline permit of the block chain nodes according to the exchange ratio of the offline permit and the common permit, the currently held permit information and the initial amount of the exchangeable offline permit.
In specific implementation, if a certain block link point can be exchanged with n offline certificates, according to the exchange ratio of the offline certificates and the common certificates, at least 1.2n common certificates are needed to exchange the n offline certificates, but the common certificates held by the certain block link point may be less than 1.2n common certificates, so that the initial amount convertible by the offline certificates needs to be further confirmed according to the number of the common certificates owned by the certain block link point, and if the actual amount convertible by the offline certificates is obtained, the actual amount convertible by the offline certificates is obtained.
And step S800, exchanging and distributing the offline permit according to the actual amount of the exchangeable offline permit.
In practical application, if the initial amount convertible by the offline voucher is adjusted to obtain the actual amount convertible by the offline voucher, an exchange confirmation message can be sent to the block chain node, the exchange confirmation message carries the actual amount convertible by the offline voucher to prompt a user whether to continue to exchange, if the confirmation exchange is received, corresponding exchange operation is carried out, the offline voucher with the amount equal to the actual amount convertible by the offline voucher is exchanged, and the exchanged offline voucher is distributed to the node; and if the user refuses the exchange, closing the exchange operation. If the actual amount convertible by the offline voucher still remains unchanged, locking the corresponding number of common vouchers according to the exchange proportion, converting the offline voucher with the actual amount convertible by the offline voucher and the like, and distributing the converted offline voucher to the node.
According to the offline evidence-passing distribution method, evidence-passing basic data are obtained, the evidence-passing basic data comprise current time evidence-passing circulation data, current held evidence-passing information of the block chain nodes and historical evidence-passing transaction records, when the block chain link points are judged to meet preset offline evidence-passing exchange conditions according to the historical evidence-passing transaction records, offline evidence-passing distribution data comprising exchange ratios of offline evidence-passing and common evidence-passing and initial amounts of exchangeable offline evidence-passing are determined according to the evidence-passing basic data, then actual amounts of exchangeable offline evidence-passing of the block chain nodes are determined, and the offline evidence-passing is exchanged and distributed according to the actual amounts of exchangeable offline evidence-passing. The block chain nodes are allowed to carry out off-line transaction from the evidence-passing level, and the amount and clearing time limit of the off-line transaction can be dynamically adjusted, so that the block chain nodes can determine the exchange amount and the use right of off-line evidence passing even in an off-line state, flexibility and high efficiency are achieved, and convenience is improved.
In one embodiment, as shown in fig. 3, determining the offline certification allocation data of the blockchain node according to the certification base data includes: step S420, according to the current held certificate information and the historical certificate transaction records, determining the initial amount of the exchangeable offline certificate, and according to the certificate circulation data at the current time, determining the exchange ratio of the offline certificate and the common certificate and the online clearing time limit of the offline certificate.
In specific implementation, the offline certification distribution data further includes offline certification on-line clearing time limit, and in general, the default value of the offline certification on-line clearing time limit is 24 hours. The determining of the offline evidence passing distribution data of the block chain node comprises determining an initial amount of redeemable offline evidence passing according to current held evidence passing information and historical evidence passing transaction records, and specifically, the initial amount of redeemable offline evidence passing can be obtained according to the maximum number of single-use evidence passing of the node and the number of currently held offline evidence passing. As described in the above embodiment, the default value of the system for the exchange ratio of the offline general certificate and the offline general certificate is 1.2:1, and the default value of the online clearing time limit of the offline certificate and the offline general certificate is 24 hours, but in a special case, the exchange ratio and the clearing time limit of the offline certificate and the offline general certificate may be adjusted according to the ratio of the currently issued offline certificate to the currently issued offline certificate, for example, the ratio of the currently issued offline certificate to the currently issued offline certificate reaches 5% or more than 5%, and then, the exchange ratio of the offline certificate to the general certificate may be adjusted to 1.3: 1, that is, 1.3 general certificates can be exchanged for 1 offline certificate, it is understood that, in other embodiments, the exchange ratio between the offline certificates and the general certificates may also be other specific values, which may be determined according to actual situations, and is not limited herein. In the embodiment, the offline evidence-based online clearing time limit and the exchange proportion are dynamically adjusted by combining the current circulation data of the system, so that the adaptability can be improved.
In one embodiment, as shown in fig. 3, determining an initial amount redeemable for offline evidence based on the current held evidence-passing information and historical evidence-passing transaction records comprises: extracting the maximum single-use voucher number in the historical voucher transaction records, determining the maximum offline voucher exchange amount according to the maximum single-use voucher number, and determining the initial amount of redeemable offline voucher according to the maximum offline voucher exchange amount and the current held voucher information.
In practical application, the initial amount of redeemable offline certificates is the amount after deducting the ordinary certificates held by the node. Specifically, the maximum value of the number of certificates used in a single transaction of the node may be extracted from historical certificate-passing transactions, if the single transaction of the node deals with 5 common certificates at most, the node can only redeem 5 offline certificates at most, and then the number of the currently held offline certificates is detected, if the node itself holds 2 offline certificates, the node can only redeem 3 offline certificates at most, that is, the initial amount of the redeemable offline certificates of the node is 3. If it is a node that has never been traded, a maximum of 1 offline pass is redeemed by default. It is understood that, in other embodiments, if the node has never been traded, the default offline certification of the maximum redemption may also be 2, which may be determined according to actual situations and is not limited herein. In another embodiment, if a certain node only applies for exchanging 3 offline certificates, and the initial amount of exchangeable offline certificates calculated according to the conditions of the node is 5, the initial amount of exchangeable offline certificates may also be adjusted to 3. In this embodiment, for the specificity of the offline certificate, the convertible amount of the offline certificate can be adjusted according to the certificate information held by each node, and the incentive effect of the offline certificate in the blockchain system can be further exerted.
In one embodiment, as shown in fig. 4, the actual amount of redeemable offline certificates for confirming blockchain nodes according to the exchange ratio of the offline certificates and the common certificates, the currently held certificate information and the initial amount of redeemable offline certificates comprises:
step S622, acquiring a plurality of common permit holding numbers in the current holding permit information;
step S624, according to the exchange ratio of the off-line general certificate and the general certificate, judging whether the general certificate holding number meets the exchange requirement corresponding to the initial amount of the exchangeable off-line general certificate;
step S626, if the sum is not satisfied, confirming the exchangeable amount of the off-line certificate again according to the holding number and the exchange proportion of the common certificate to obtain the actual amount of the exchangeable off-line certificate;
in step S628, if yes, the initial amount of the redeemable offline voucher is used as the actual amount of the redeemable offline voucher.
In specific implementation, assuming that the exchange ratio of the off-line general certificate to the general certificate is 1.2:1, if the initial amount convertible by the off-line general certificate is n, 1.2n general certificates are needed to meet the conversion requirement for converting n off-line general certificates. Therefore, acquiring the number of held common certificates in the current held common certificate information, then judging whether the number of held common certificates meets the exchange requirement corresponding to the initial amount of the exchangeable off-line common certificates, namely, the number is greater than or equal to 1.2n according to the exchange ratio of the off-line common certificates to 1.2:1, if not, reconfirming the exchangeable amount of the off-line common certificates according to the number of held common certificates and the exchange ratio, for example, if the exchangeable initial amount of the off-line common certificates is 5, according to the preset exchange requirement, at least 6 common certificates are needed to exchange 5 off-line common certificates, and if the number of the currently held common certificates is only 5, according to the exchange ratio, 5 is greater than 1.2 x 4=4.8, the actual amount of the exchangeable off-line common certificates of the node is 4; if the number of the common certificates currently held by the node is 8, the initial amount of the redeemable offline certificates is used as the actual amount of the redeemable offline certificates, and 5 equal amounts of the redeemable offline certificates obtained in the preorder are maintained. In this embodiment, whether the number of the held common certificates meets the exchange requirement corresponding to the initial amount of the exchangeable offline common certificates is judged according to the exchange ratio of the offline common certificates and the common certificates, so that the problem that the number of the held common certificates is not enough to exchange the offline common certificates with the initial amount of the exchangeable offline common certificates and the like can be effectively solved.
In one embodiment, after the offline permit is redeemed and distributed according to the actual amount of redeemable offline permits, the method further comprises: step S900, when detecting that the block link node carries out off-line certification transaction, recording off-line certification transaction data and sending an on-line clearing notification message to the block link node, capturing the network state of the block link node, wherein the on-line clearing notification message carries an off-line certification on-line clearing time limit; step S920, when the network status of the blockchain node is captured as the online status, calculating offline certification transaction data according to the offline certification online clearing time limit.
Generally, without a network, a node cannot use a common certificate, and the common certificate must be connected to the network to be used. After the offline permit is exchanged and distributed to the node, the node can use the offline permit to perform offline permit transaction under the state without network, generally face-to-face use, two parties exchange address information, local nodes of the two parties (such as in mobile phone application) record offline permit transaction data, and when networking is performed, networking clearing is performed. When capturing the off-line pass of the node in the off-line state, detecting whether the transaction is in the off-line pass limit of the allowed transaction, if so, recording off-line pass transaction data on the local node, and sending an online clearing notification message carrying the off-line pass online clearing time limit to the block link node to prompt a user of the node to perform online clearing on the off-line pass transaction in the off-line pass online clearing time limit, waiting for the next online clearing of the block link node, and capturing the network state of the block link node. And when the network state of the node is captured to be the online state, calculating the offline certification transaction data according to the offline certification online clearing time limit. For example, if the node goes online (connects to the network) within the offline-credentialing online clearing time limit, the offline-credentialing transaction data is calculated. If the offline evidence-passing online clearing time limit is exceeded, a certain amount of commission charge can be calculated and deducted according to the exceeded time length. Specifically, the deduction rule of the commission fee can be according to the payment rule of the late payment of the current industry, similar to the overdue payment of the credit card, for example, several thousandths of the commission fee is collected every more than 24 hours, which is determined according to the circumstances and is not limited herein. In this embodiment, the normal operation of the blockchain system can be maintained by sending an online clearing notification message of the offline certification online clearing time limit to the blockchain point and calculating the offline certification transaction data in time.
