and S110, responding to the fund item initiating transaction request, and extracting fund item information from the fund item initiating transaction request.
The fund item initiating transaction request is a request sent to the blockchain node to initiate a fund item, and the fund item can be a donation item, a conversion item or an auction item and other items related to fund transaction circulation. The funding item initiation transaction request includes funding item information such as funding item initiator information, funding information for the funding item initiator, funding item initiation time, funding item related to an amount of funds, an amount condition, and a funding destination. For example, in the case of a money item donation item, the money item initiating transaction request may include, a demand for donation, certification material, and the like. The donation demand can be the amount of the required donation and/or the type and amount of the required donation materials. The certification material may include information such as diagnostic materials for diseases, documents for medical consumption, special identification (such as a disability certificate and a police certificate), property certificates (a real estate, a vehicle), and the like.
In an alternative embodiment, the funding project initiator maintains a blockchain node and accesses the blockchain network along with the blockchain node implementing the present embodiment. The fund item initiator sends a fund item initiation transaction request to a block chain node maintained by the fund item initiator, and the block chain node transmits the fund item initiation transaction request to a block chain node executing the embodiment, so that the block chain node executing the embodiment extracts fund item information from the fund item initiation transaction request in response to the fund item initiation transaction request.
In another optional implementation, the funding project initiator does not need to maintain the blockchain node, and the blockchain node implementing the embodiment maintains the funding project processing platform, which may be specifically represented in the form of a website or the backend of an application program. Based on this, the fund item initiator sends a fund item initiation transaction request to the block link node through the fund item processing platform, for example, the fund item information is written into a front-end webpage provided by a website or a front-end page of the application program and sent to the back end of the application program.
And S120, sending an audit transaction request of the fund item information to a plurality of users through a block chain network according to the fund item information, and receiving an audit result fed back by the plurality of users in response to the audit transaction request.
The multiple users refer to users who participate in checking fund project information, the coverage of the users is wide in order to guarantee the authenticity and the effectiveness of the checking, and the multiple users relate to various industries and various age groups. Alternatively, users of the target application having a wide audience are selected as the users participating in reviewing the funding item information. An audit transaction request is a request sent from a block chain node to a plurality of users to audit funding item information, including funding item information.
Optionally, an audit transaction request of the fund project information is sent to a plurality of users based on a consensus mechanism, where the consensus mechanism is a multi-party collaboration mechanism. The method aims to guarantee that multiple parties finally achieve a mutually approved consistency result in a safe, credible and difficult-to-cheat mode. The consensus mechanism in the blockchain is a technical means and a mechanism for deciding which node finally participates in accounting in the case of multi-node participation.

Optionally, points are set in accounts registered by a plurality of users in the blockchain network. Wherein the user points can be exchanged for products of corresponding value, such as train ticket coupons, merchandise coupons, etc. And if the user participates in the examination of the fund item information, the user points in the user account are adjusted according to the success of the fund item in the uplink adjustment. Illustratively, if the auditing result fed back by a user matches the result of whether the fund item is successfully linked, the user is rewarded with a set value point; correspondingly, if the number of times that the audit result fed back by a user does not match the result of whether the fund item is successfully linked exceeds the set number of times, the credit of the value set by the user is correspondingly deducted. Here, the integral of the set value may be 10 integrals, and the set number of times may be 3. The method is not limited herein, and is determined according to actual conditions. The credit is set in the account of the user, and the credit of the user in the account of the block chain network is adjusted according to the auditing result fed back by the user and the result whether the fund project is successfully linked, so that the enthusiasm of the user for participating in the project auditing and the strictness degree of the user auditing are improved, and the accuracy of the fund project linking is further improved.
In another optional implementation, the target application manufacturer maintains a blockchain node, and the blockchain node executing the embodiment sends an audit transaction request to the blockchain node maintained by the target application manufacturer. The block link points maintained by the target application manufacturer convert the audit transaction request into an audit request (including the fund item information) supported by the target application and send the audit transaction request to a plurality of users of the target application. And the plurality of users receive the auditing request through the target application program, audit the fund item information in the auditing request to obtain an auditing result, feed back the auditing result to the block chain node maintained by the target application program manufacturer, and further feed back the auditing result to the block chain node executing the embodiment.
The checking of the capital item information comprises checking whether the capital item really exists, checking the authenticity of the information of a capital item initiator, checking whether the capital item initiator has the capital item qualification, checking whether the capital item relates to the correct capital amount and the like.
And S130, if the auditing result is that the fund item information passes the checking, performing uplink storage on the fund item information.
And the user responds to the transaction auditing request to audit the fund item information and feeds back an auditing result, wherein the auditing result fed back by the user can comprise passing, failing, abandoning and the like. And the block chain link point processes the received auditing results fed back by the plurality of users to obtain the final auditing result.
And if the result of the verification is that the fund item information is true and valid, the block link point performs uplink storage on the fund item information. If the result of the check is not passed, it indicates that the capital item information is not true and valid, and the capital item information cannot be linked for storage at this time, a manual check or a program check needs to be performed on the capital item information to further determine whether the capital item information is true and reliable.
The uplink storing of the fund item information may comprise: recording the fund project information as transaction data in the current block through a block chain node (namely a current block generation node); and sending the current block to other block chain nodes for verification. After the verification is passed, storing the current block in a block chain; and if the verification fails, sending block failure information containing the current block identifier to other nodes in the block chain network.
Optionally, if the result of the audit is passed, the block link point stores the fund item information into a locally maintained database, and/or stores the fund item information into the fund item processing platform.
Optionally, if the number of the passed auditing results is greater than the set threshold value in the auditing results fed back by the multiple users, uplink storage is performed on the fund item information. For example, the set threshold may be 70% of the total number of users participating in the audit and feeding back the audit result, which is not limited herein and is determined according to the actual situation. The auditing results fed back by a plurality of users are integrated, and the auditing results of most users are taken as the final auditing result, so that the auditing results are more convincing.
The embodiment of the invention sends the fund item information to a plurality of users for auditing through the block chain network, and the auditing result is more reliable and the auditing efficiency is higher through the auditing of the users; in addition, the whole processing process of the fund item is completed through the block chain network, and the authenticity of the fund item information is further ensured by utilizing the property that the block chain network is not falsified and forged.
