technical field

The present invention relates to the technical field of block chains, in particular to an information verification method, device and system based on block chains.

Background technique

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain rights and interests between different nodes in the blockchain system. Blockchain is the underlying technology of Bitcoin, like a database ledger, recording all transaction records.

At present, in blockchain-based applications, blockchain technology is mainly used to record transaction events to provide traceability of all links in transaction events. However, the authenticity of the events recorded by each node in the transaction event can only be identified based on a third party outside the blockchain. For example, the task proposed by the publisher of the transaction task is to provide acceleration for multiple URLs, task calculation According to its own completion status, the information on accelerating a certain URL, that is, the contribution value, is added to the blockchain in the form of transaction events. At the same time, the publisher assigns corresponding rewards. In this process, how to determine that the task calculation party has indeed completed the content recorded in the transaction event can only be verified by the publisher through the third-party data statistics, and the results of this verification process are the same as those recorded in the blockchain. There must be a certain lag in time for adding data, and once the task calculator uploads fake data, the publisher at this time has already allocated the corresponding rewards, and it needs to be recovered from the task calculator. This causes a lot of additional workload for the publisher during the operation process, and this drawback also limits the promotion of applications based on blockchain technology.

Detailed ways

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

The embodiment of the present invention provides a blockchain-based information verification method, which is applied to a verification node. Generally, the verification node does not produce data uploaded to the blockchain, but collects relevant information uploaded by both parties of the transaction event for comparison. The concrete steps of this method are as shown in Figure 1, and this method comprises:

101. Obtain the completion information of the transaction event uploaded by the task calculation party and the event identifier of the transaction event.

Each node in the existing blockchain will generate relevant information about transaction events, and new blocks will be generated based on these relevant information. However, the verification node in the embodiment of the present invention will not generate relevant information about transaction events, but only maintains the information of the block chain in the node, and detects the information in the block. When a transaction event uploaded by the task computing party is found When the completion information of the transaction event is obtained, the completion information and the event ID of the transaction event are obtained. For example, take A (task issuer) as an example to issue a URL acceleration task, B (task calculation party) receives the task and executes the acceleration of the URL, and then uploads the acceleration result of the URL as a new block to the zone In the block chain, for existing applications based on block chain technology, A will pay B the corresponding remuneration according to the acceleration results of B. However, in this embodiment, a verification node C is added, and C obtains the acceleration result uploaded by B, and at the same time obtains the event identifier of the transaction event. The event identifier is the unique identification information for the URL acceleration task, which can be "for URL Acceleration task" transaction event number, which can be the hash value calculated for the task name, participant name and other information.

102. Obtain the verification information of the transaction event uploaded by the task issuer according to the event identifier.

Wherein, the verification information is the information of the task computing party that the task issuing party checks and completes the transaction event. The verification information includes at least the name of the task calculation party, the result of the corresponding transaction completion event, and other information. Generally, the verification information is the relevant result of the task calculation party participating in the transaction event obtained by the task issuer through specific data statistics information or a third-party statistical agency, and the specific content of the result is not limited in this embodiment and format, according to the above example, the result of URL acceleration may be how many specific URLs are accelerated, or the specific degree of acceleration for a URL, such as specific increased traffic information. It can be seen that this step corresponds to the above example, and C will obtain the verification information uploaded by A from the blockchain according to the event identifier of the transaction event.

103. Analyze the completion information and verification information according to the signature information in the blockchain.

In blockchain technology, the data in a block includes uploading the hash value of the previous block, transaction information of transaction events, signature information, time stamp and other information into a new block, and then uploading the block. block chain, after connecting it to the previous block. Therefore, to obtain the completion information and verification information in the above steps, the verification node needs to analyze the information in the corresponding block according to the specific signature information to obtain the completion information and verification information of the corresponding transaction. Among them, the signature information is provided by Upload user-defined identifying signature information. The specific implementation of this step is the same as the process of making and analyzing block data in the existing blockchain, so it will not be repeated here.

104. Determine whether the check information contains completion information.

Generally, there will be multiple task calculators in the verification information uploaded by the task issuer. Therefore, what is judged in this step is, when there is only one task calculator in the verification information, it is judged whether the task calculator corresponds to the completion information. task calculator, and when there are multiple task calculators in the verification information, it is judged whether the task calculator corresponding to the completion information is included in these task calculators. Corresponding to the above example, C judges whether B is included in the name list of all the task calculation parties included in the verification information uploaded by A, and if yes, then execute step 105, and if not, it means that B may have cheated. , C will also send a corresponding warning message to A, prompting that B recorded in A's blockchain may have cheated.

105. Send the task computing party verification passing information to the task issuer.

Through the verification information, the task issuer can confirm that the completion information uploaded by the task calculator in the blockchain is authentic and reliable, and then can perform operations such as remuneration payment.

It can be seen from the above examples that the blockchain-based information verification method provided by the embodiment of the present invention is applied to the added verification node, and the verification node also maintains the same blockchain data, but does not generate new blocks. The block data only acquires and compares the transaction information for the participants of the same transaction event in the blockchain data, and informs the task issuer of the transaction event of the comparison result, so as to realize the real-time verification of the transaction information, which is different from the existing Based on the application of blockchain technology, the task issuer in the present invention will pay remuneration according to the verification results of the verification nodes, so as to prevent the task calculation party from issuing false completion information through cheating to obtain rewards.

Corresponding to the example shown in Figure 1, based on the information verification method of the present invention, the task issuer will perform subsequent steps according to the information of the verification node during the execution process, especially when paying remuneration, no longer according to the task in the blockchain. The completion information uploaded by the calculation party is used for payment. For this, the specific steps performed by the task issuer in the process of implementing the information verification method are shown in Figure 2, including:

201. Count the verification information of the transaction event.

Wherein, the checking information is the information of the task calculating party who has checked and completed the transaction event, specifically including the name of the task calculating party and corresponding completion information. The verification information can be generated by the task issuer according to its own statistical data, or it can be the verification information obtained through the statistics of a third-party statistical agency or platform. Specifically, the data content and format in the information are not limited in this embodiment. In the prior art, the task issuer will also count the same verification information. Therefore, how to count the verification information is not done in this step. Be specific.

202. Upload the verification information to the blockchain.

In this embodiment, the task issuer will upload the verification information as the relevant information of the transaction event to the blockchain as information in a block. The specific uploading process is the same as the process of creating a new block in the existing blockchain. It uses the signature information of the task issuer and the hash value of the last block in the blockchain maintained by its own node to compare with the verification information. Create a new block, and the specific calculation method will not be described in detail here.

203. Receive verification passing information of the transaction event.

Among them, the verification passing information is the verification information obtained by the verification node according to the above-mentioned uploaded verification information and the completion information of the same transaction event uploaded by the task calculation party in the blockchain, that is, in the above-mentioned Figure 1, it is obtained by the verification node after execution The verification passed information.

It should be noted that, in this step, only after the verification node passes the comparison verification, will it receive the corresponding verification information. For the task calculation party that has not passed the comparison verification, there are generally two situations, one is that the task calculation The other party has not uploaded the completion information, and the other is that there is a discrepancy in the completion information uploaded by the task calculation party. At this time, the early warning information sent by the verification node will be received.

204. Determine to pay remuneration to the task calculation party included in the verification passing information.

According to the verification pass information received in step 203, the task calculation party is extracted, and the task calculation party is determined to be a user who can pay remuneration. The specific payment method is not limited in this embodiment, and may be direct payment or indirect payment on behalf of others.

It can be seen from the above example shown in Figure 2 that a blockchain-based information verification method provided by the embodiment of the present invention is applied to the node where the task issuer is located. The verification information is added to the blockchain data as the relevant information of the transaction event, and the payment is based on the verification information sent by the verification node. The relevant information of the transaction event uploaded by the task issuers shall verify the information to ensure that both parties agree with the transaction result of the transaction event, that is, the transaction participants do not think that the other party has cheated. The payment confirmation process optimizes the remuneration payment operation and avoids additional workload caused by payment disputes.

Further, in the above-mentioned blockchain-based information verification method shown in Figure 2, for the payment method determined by the task calculation party in step 204, one of the feasible embodiments is determined by the task calculation party according to Check the completion information of the task calculator recorded in the information, combined with the corresponding reward distribution mechanism, which is pre-set, and directly pay the corresponding reward to the task calculator.

In another feasible embodiment, the corresponding reward is paid by the verification node. For this, the task issuer needs to send the reward distribution mechanism to the verification node in advance, and pay the total transaction reward for completing the transaction event. When the task issuer When the verification pass information is received, the verification node will send the payment instruction information to the verification node, and then the verification node will calculate the reward due to the task calculation party according to the reward distribution mechanism and pay accordingly. Of course, it is also possible for the task issuer to calculate the paid remuneration, inform the verification node of the amount of remuneration to be paid through the instruction information, and then the verification node will pay the task calculation party. In this way, the amount of data that the task issuer needs to calculate can be further reduced, and the verification node will pay for it.

Based on the above-mentioned embodiments shown in Fig. 1 and Fig. 2, the verification node and the node where the task issuer is located may be set in the same node at the same time or in different nodes in practical applications. In the case of being set on different nodes, each node in the embodiment of the present invention will maintain the same blockchain data.

Further, for the verification node in the embodiment shown in Figure 1 to specifically obtain the verification information and the operation process of further paying remuneration to the task calculation party based on the information verification method, a blockchain-based The method of information verification is described in detail, and the steps include:

301. Obtain the completion information of the transaction event uploaded by the task calculation party and the event identifier of the transaction event.

302. Obtain verification information of the transaction event uploaded by the task issuer according to the event identifier.

Since the blocks in the blockchain are connected in series according to time, under normal circumstances, the time point when the task issuer calculates the verification information of the transaction event and uploads it to the blockchain will be later than the time when the task calculation party completes the information upload. to the time point in the block chain, therefore, in this embodiment, when obtaining the verification information from the block chain data, the specific operation is: first judge whether there is an object uploaded by the task issuer in the block where the completion information is located The verification information of the transaction event is to judge whether the task issuer has counted and uploaded the corresponding verification information within the time period when the task calculation party uploaded the completion information. If the verification information corresponding to the transaction event is not found in the block, the verification information corresponding to the transaction event is searched in the next block of the block.

Furthermore, since the blocks in the blockchain will continue to increase, if the task issuer does not upload the verification information of the transaction event, then the verification node will continue to search as the blocks increase, resulting in a shortage of computing resources. waste. In order to avoid this situation, in another embodiment of the present invention, the search time period can be preset, such as 5 minutes, 1 hour, etc., when the verification node has not found the verification information corresponding to the transaction event within this time period , the verification node sends a prompt message to the task issuer, informing the task issuer that the verification information of the transaction event has not been uploaded to the blockchain, and at the same time, stops searching for the verification information of the transaction event.

303. Analyze the completion information and verification information according to the signature information in the blockchain.

304. Determine whether the verification information contains completion information.

305. Send the task computing party verification passing information to the task issuer.

The contents of the above steps 303 to 305 are the same as the steps 103 to 105 in the embodiment shown in FIG. 1 , and will not be repeated here.

It should be noted that, for the above steps 101 and 102, there is no logical sequence between obtaining the completion information of the transaction event uploaded by the task calculation party and obtaining the verification information of the transaction event uploaded by the task issuer.

306. Obtain the transaction reward paid by the task issuer for completing the transaction event and the reward distribution mechanism.

Based on the execution of the above steps, after the verification node feeds back the successful comparison message to the task issuer in the form of verification passing information, in the embodiment of the present invention, the verification node will continue to perform the step of reward distribution. For this reason, before paying the task calculation party, two questions must be clarified:

1. Verify whether the node is eligible to pay the task calculator.

2. Determine the amount of remuneration paid to the task calculator.

For the first question, the verification node can obtain the authorization of the task issuer through the indication information. Of course, the embodiment of the present invention does not limit other authorization methods. For example, node authentication: pre-confirm that the verification node can directly submit the task to the task calculation party. Payment of remuneration, etc.

For the second question, by obtaining the remuneration distribution mechanism provided by the task issuer, the task calculation party's due reward is calculated according to the completion information of the task calculation party or the content recorded in the task issuer's verification information, such as , the task calculator can get a reward of 1M traffic for accelerating a URL, then calculate the corresponding reward value according to the number of tasks completed by the task calculator.

Further, when the verification node pays the task calculation party, the verification node in the embodiment of the present invention will first obtain the transaction reward for completing the transaction event from the task issuer, after calculating the reward value to be paid, from the The corresponding value is extracted from the transaction reward to the task calculator, and the payment voucher is sent to the task issuer.

307. Calculate the remuneration due to the task calculation party according to the information recorded in the verification information and the remuneration distribution mechanism, and pay the remuneration to the task calculation party.

In this embodiment, the payment value is calculated by the verification node. Of course, it can also be set so that the task issuer calculates the reward value and sends it to the verification node, and then the verification node directly sends the reward to the task according to the received reward value. calculation side.

The above is a specific implementation plan for the data recording and reward distribution of the verification node in the application based on blockchain technology. According to the above operation with the verification node, it can be seen that the verification node can be based on the block in the blockchain. Data, the comparison and verification of the data uploaded by the participants in the transaction event, so as to avoid unilateral cheating in the transaction process, and then generate payment disputes for transaction remuneration.
