基于DAO的区块链智慧社区问题解决方法及系统DAO-based blockchain smart community problem solving method and system

技术领域technical field

本发明涉及区块链技术领域，尤其涉及一种基于DAO的区块链智慧社区问题解决方法及系统。The present invention relates to the technical field of blockchain, and in particular, to a method and system for solving the problem of a blockchain smart community based on DAO.

背景技术Background technique

随着社会经济的高速发展，社区的规模和智能化程度在不断提升，社区中出现的环境、安全、生活等方面的民生问题也在增多。社区民生问题关乎人民生活水平的提高，针对社区中的民生问题，政府设立了各种负责的管理部门。民生问题往往需要多个部门协同处理。多部门合作不易监督，容易出现各部门推脱责任、互不关心、无作为等情况，导致民生问题解决进程缓慢。除此之外，监管机制也不完善，没有保存各部门完整的工作记录，无法追溯各部门的工作进度以及工作责任。同时，社区居民用户在社区问题的解决过程中参与度不高。With the rapid development of the social economy, the scale and intelligence of the community are constantly improving, and the people's livelihood problems in the environment, safety, and life are also increasing. Community livelihood issues are related to the improvement of people's living standards. For the livelihood issues in the community, the government has established various responsible management departments. People's livelihood issues often need to be dealt with by multiple departments. Multi-departmental cooperation is not easy to supervise, and it is easy for various departments to shirk their responsibilities, ignore each other, and do nothing, which leads to a slow process of solving people's livelihood problems. In addition, the supervision mechanism is not perfect, the complete work records of each department are not kept, and the work progress and work responsibilities of each department cannot be traced. At the same time, community resident users are not highly involved in the process of solving community problems.

针对上述问题，申请公布号为CN111311410B的专利公布了一种基于区块链的社区问题多部门协作处理系统及方法，提出“自上而下”的处理社区问题方法，使用区块链存储社区问题的完整部门认领处理流程，实现了相关部门之间的有效监督，提升了社区问题的处理效率。申请公布号为CN112785168A的专利公开了一种基于区块链的社区问题多部门认领处理系统及方法，提出“自下而上”的处理社区问题，使用区块链记录社区问题的完整处理流程，保证了问题处理记录的安全性和可追溯。In response to the above problems, the patent application publication number CN111311410B discloses a blockchain-based multi-departmental collaborative processing system and method for community problems, and proposes a "top-down" method for dealing with community problems, using blockchain to store community problems. The complete departmental claim processing process has achieved effective supervision between relevant departments and improved the processing efficiency of community issues. The patent application publication number CN112785168A discloses a blockchain-based multi-department claim processing system and method for community issues, proposes a "bottom-up" approach to community issues, and uses blockchain to record the complete processing flow of community issues. The security and traceability of problem handling records are guaranteed.

上述专利虽然使用区块链保证了数据的安全和可追溯，但是上述现有技术未完全解决流转分配不精确的问题；以及未设置激励措施和奖惩制度，各用户缺乏动力且难以达成处理问题的一致，社区居民用户参与度不高；并且对区块链存储性能缺乏评估，业务系统无法高效的与区块链进行交互，缺乏灵活性和外部可交互性，问题记录内容无法灵活扩展。Although the above-mentioned patent uses blockchain to ensure the security and traceability of data, the above-mentioned existing technologies do not completely solve the problem of inaccurate distribution of circulation; and there is no incentive measure and reward and punishment system, each user lacks motivation and is difficult to achieve. Consistent, community resident user participation is not high; and there is a lack of evaluation of blockchain storage performance, business systems cannot efficiently interact with blockchain, lack of flexibility and external interactivity, and the content of problem records cannot be flexibly expanded.

以下，请参照图2，图2为本发明提供的一种基于DAO的区块链智慧社区问题解决方法的时序图，结合图2，具体说明本方法的应用流程如下：Below, please refer to FIG. 2, which is a sequence diagram of a DAO-based solution to the problem of a blockchain smart community provided by the present invention. In conjunction with FIG. 2, the application process of the method is specifically described as follows:

如图3所示，基于DAO的区块链智慧社区问题处理系统由S101-S110用户模块、S200区块链Web系统界面模块、S300区块链Web系统模块、S400消息队列模块、S500居民系统模块组成，S110用户将S101问题信息，S102评价信息利用S500居民系统模块通过S400消息队列模块发送到S300区块链Web系统模块；S110用户将S103问题处理操作执行结果和执行过程产生的数据通过S200区块链Web系统界面模块分类后存储至S300区块链Web系统模块；S110用户可以通过S200区块链Web系统界面模块访问S300区块链Web系统模块查询数据：As shown in Figure 3, the DAO-based blockchain smart community problem processing system consists of S101-S110 user modules, S200 blockchain web system interface modules, S300 blockchain web system modules, S400 message queue modules, and S500 resident system modules The S110 user sends the S101 problem information and S102 evaluation information to the S300 blockchain web system module through the S500 resident system module through the S400 message queue module; the S110 user sends the S103 problem processing operation execution result and the data generated by the execution process through the S200 area The block chain web system interface module is classified and stored in the S300 block chain web system module; S110 users can access the S300 block chain web system module through the S200 block chain web system interface module to query data:

本方法具体实现步骤如图4所示：The specific implementation steps of this method are shown in Figure 4:

S1：终端连接S500居民系统，通过登录接口验证(首次登录进行用户注册)用户身份信息，验证通过后填写问题基础信息，由网格长用户通过S500居民系统对新创建的问题信息进行立项确认，确认立项后将项目基础信息(Project)发送至消息队列。S1: The terminal is connected to the S500 resident system, and the user identity information is verified through the login interface (user registration is performed for the first time). After the verification is passed, the basic problem information is filled in. The long grid user will confirm the newly created problem information through the S500 resident system. After the project is confirmed, the project basic information (Project) is sent to the message queue.

具体地，在步骤S1中：Specifically, in step S1:

所述终端设备包括手机、平板、PC端、笔记本等，连接S500居民系统的方式有支付宝小程序、微信小程序、APP、网页等。The terminal devices include mobile phones, tablets, PC terminals, notebooks, etc., and the ways to connect to the S500 resident system include Alipay applet, WeChat applet, APP, web page, and the like.

所述登录接口由用户通过居民系统“账号-密码”验证后调用，从链下数据库查询登录账号，若查询为空，则调用用户注册智能合约对本次登录输入的“账号-密码”进行注册，若查询存在，则从区块链上查询本次登录输入账号的所对应的密码，并与本次登录输入的密码进行对比，若一致则返回登录成功。The login interface is called by the user after verifying the "account-password" of the resident system, and the login account number is queried from the off-chain database. If the query is empty, the user registration smart contract is called to register the "account-password" input for this login. , if the query exists, query the password corresponding to the account entered in this login from the blockchain, and compare it with the password entered in this login. If it is consistent, the login is successful.

上述调用用户注册智能合约对本次登录输入的“账号-密码”进行注册是将本次登录所输入的“账号-密码”加密上链，并将本次登录输入账号写入链下数据库的User表中，并加密上链存储，User表设计如图5中的链下注册用户数据库以及表1所示：The above-mentioned invoking the user registration smart contract to register the "account-password" entered in this login is to encrypt the "account-password" entered in this login on the chain, and write the account entered for this login into the User of the off-chain database. In the table, and encrypted and stored on the chain, the User table is designed as shown in the off-chain registered user database in Figure 5 and Table 1:

上述密码权限高度为Master Password>Owner Key>Active Key>Signin Key、Remark Key。The above password permissions are Master Password>Owner Key>Active Key>Signin Key, Remark Key.

上述本项目使用的CTN，绝大部分作为工作部门认领任务后工作经费，少部分作为此次处理任务的手续费用。Most of the CTNs used in the above project are used as work expenses after the work department claims the task, and a small part is used as the handling fee for this task.

上述手续费用的设置为满足两部分的需求，分别为居民用户奖励和投票用户奖励。The above fees are set to meet the needs of two parts, namely, resident user rewards and voting user rewards.

上述发布项目基础信息(Project)为网格长用户将项目描述等信息中的大文件数据(例如：图片、文档)存储在IPFS中，将在IPFS中存储项目文件反馈的文本信息与Project的文本信息绑定序列化，存储发布到区块链Web系统的主链中；其中，上述IPFS是一种全新的超媒体文本传输协议，基于分布式存储技术，可提供较大的数据存储能力，本方法的大型文件数据全部利用IPFS进行存储。The above-mentioned basic project information (Project) is for grid long users to store the large file data (such as pictures, documents) in the project description and other information in IPFS, and the text information of the project file feedback and the text of the Project will be stored in IPFS. The information is bound and serialized, stored and published in the main chain of the blockchain web system; among them, the above IPFS is a new hypermedia text transmission protocol, based on distributed storage technology, which can provide greater data storage capacity. The large file data of the method is all stored using IPFS.

上述各用户认领发布的问题是指S300区块链Web系统中各个用户分析发布的项目信息与本部门的职能是否匹配，分析完成后与发布本项目的网格长建立协定对本项目部分或全部认领。由网格长用户进行最优工作部门的选择。The above-mentioned problem of user's claim and release refers to whether the project information analyzed and released by each user in the S300 blockchain web system matches the function of the department. After the analysis is completed, an agreement is established with the grid leader who released the project to claim part or all of the project. . The selection of the optimal work sector is made by the grid-length user.

上述建立协定是指工作部门确认认领任务后与任务发布者(即网格长)建立协商通道，互相提交认领的部分或全部任务内容和使用的CTN数量，重复提交至达成一致，将协商的过程以及结果存储在区块链Web系统的侧链中，最终在区块链主链中进行结算。若网格长与不同的工作部门就相同的认领任务达成一致，由网格长进行最优部门选择(若选择失败，网格长用户会受到一定的惩罚)，选定后，系统自动冻结网格长用户和被选定工作部门用户的CTN，被选择部门开始处理认领的任务。The above establishment agreement means that the work department establishes a negotiation channel with the task issuer (that is, the grid leader) after confirming the claimed task, and submits part or all of the claimed task content and the number of CTNs used to each other, and submits it repeatedly until an agreement is reached, and the negotiation process is completed. And the results are stored in the side chain of the blockchain web system, and finally settled in the blockchain main chain. If the grid length and different work departments reach an agreement on the same claim task, the grid length will select the optimal department (if the selection fails, the grid length user will be punished to a certain extent). After the selection, the system will automatically freeze the network. The CTN of the user in the cell length and the user of the selected work department, and the selected department starts to process the claimed task.

上述系统自动冻结的CTN数量为网格长用户和被选定工作部门用户达成的最终协定中的任务所需CTN数量，若任务未正常完成，则将被选定工作部门用户的被冻结的CTN加入到重新发布任务的CTN中。The number of CTNs automatically frozen by the above system is the number of CTNs required for the task in the final agreement reached between the grid long user and the user in the selected work department. If the task is not completed normally, the frozen CTN of the user in the selected work department will be used. Added to the CTN of the repost task.

上述问题处理工作执行Credit证明转化、冻结、发放和问题认领等步骤的过程中产生的数据由区块链Web系统侧链进行存储。The data generated in the process of performing the steps of credit proof conversion, freezing, issuance, and problem claiming in the above problem handling work are stored by the side chain of the blockchain web system.

S4：工作进行中若调用了外部资源，费用由调用工作部门用户在系统中发起支付请求，通过系统支付。工作部门用户处理认领的工作时若实际进度与达成协定中的预期有误或未按时完成工作，网格长用户可以发起任务重新发布裁定申请，核查部门裁定后，对工作失误部门进行惩罚并重新发布认领的任务信息。S4: If an external resource is called during the work, the user of the calling department initiates a payment request in the system and pays through the system. If the actual progress is wrong with the expectations in the agreement or the work is not completed on time when the user of the work department is processing the claimed work, the grid leader user can initiate a task to re-issue the application for ruling. Publish the claimed task information.

具体地，在步骤S4中：Specifically, in step S4:

上述外部资源为属非政府资源的社会机构，如：家政公司、建筑公司等。The above-mentioned external resources are social institutions that are non-governmental resources, such as: housekeeping companies, construction companies, etc.

上述调用外部资源的费用通过系统支付为工作部门向S300区块链Web系统提交支付请求，通过S300区块链Web系统进行费用支付，根据工作部门与外部资源协定规则选择支付方式。The above-mentioned fees for calling external resources are paid by the system for the work department to submit a payment request to the S300 blockchain web system, and the fee is paid through the S300 blockchain web system, and the payment method is selected according to the agreement rules between the work department and external resources.

上述通过S300区块链Web系统进行费用支付为工作部门向系统发送付款请求，需要填写外部资源收款账户、收款金额和详细的支付方式。工作部门还需将在工作中与外部资源签订的合同文件等材料上传至IPFS存储后利用区块链进行存证；The above-mentioned fee payment through the S300 blockchain web system means that the work department sends a payment request to the system, and needs to fill in the external resource collection account, the payment amount and the detailed payment method. The work department also needs to upload the contract documents and other materials signed with external resources at work to IPFS for storage and then use the blockchain for storage;

上述选择支付方式是综合外部资源的质保期、信誉度等因素，在支付费用时，选择一次性结清或分阶段支付等不同方式。The choice of payment method above is based on factors such as the warranty period and creditworthiness of external resources. When paying fees, different methods such as one-time settlement or staged payment are selected.

所述网格长发起任务重新发布裁定申请是在工作部门处理认领任务失败时，网格长经过裁定后重新发布任务，重新与其他部门进行建立并达成协定，进行任务处理。若此次失败的工作部门是由网格长用户在不同部门中进行选定的部门，则网格长用户会因选择失败受到惩罚。The grid leader initiates a task re-issuing adjudication application. When the work department fails to process the claim task, the grid leader re-issues the task after adjudication, and re-establishes and reaches an agreement with other departments to process the task. If the job department that fails this time is a department selected by the grid long user among different departments, the grid long user will be punished for failing to select.

上述网格长用户受到惩罚是未正确选择处理任务的最优部门。会将网格长被冻结的部分CTN加入到此次项目处理的投票奖励中。The above grid-long users are penalized for not correctly choosing the optimal sector to handle the task. Some CTNs whose grid lengths are frozen will be added to the voting rewards for this project.

S5：各工作部门将认领的任务处理完成后，由居民通过S500居民系统提供此次项目处理的评价意见供网格长办结参考。网格长根据居民评价意见进行任务办结，并将处理过程的可公开的信息进行发布。S5: After each work department has completed the processing of the claimed tasks, the residents will provide the evaluation opinions of the project processing through the S500 resident system for the grid leader to complete the reference. The grid leader completes the task according to the residents' evaluation opinions, and publishes the publicly available information of the processing process.

具体地，在步骤S5中：Specifically, in step S5:

所述居民提供评价意见为在本项目全部处理结束后，结合实际处理情况，通过S500居民系统向网格长用户提交任务处理完成情况和完成度评价。The evaluation opinions provided by the residents are to submit the task processing completion status and completion degree evaluation to the grid long users through the S500 Resident System after all the processing of the project is completed and in light of the actual processing conditions.

网格长用户办结项目是指网格长用户收到居民用户的项目完成评价后，将此次项目作办结处理(办结信息的文件数据利用IPFS进行存储)，网格长用户将此次项目处理的可公开信息在S300区块链Web系统中进行公布(包括项目内容认领结构、认领使用CTN等信息)，并进入项目投票阶段。The long grid user to complete the project means that the long grid user will complete the project after receiving the project completion evaluation from the resident user (the file data of the settlement information is stored by IPFS). The publicly available information processed by the sub-project will be announced in the S300 blockchain web system (including the project content claim structure, claim and use of CTN and other information), and enter the project voting stage.

S6：网络中未参与问题的用户对公开的信息进行合理度投票，若投票结果为不合理，则开始质疑环节，并由核查部门进行裁决。项目结束后，网格长用户按照事先达成的协定进行Credit证明的发放。S6: Users in the network who did not participate in the question vote on the reasonableness of the public information. If the voting result is unreasonable, the questioning session will begin, and the verification department will make a ruling. After the end of the project, the long grid users will issue the Credit certificate according to the agreement reached in advance.

具体地，在步骤S6中：Specifically, in step S6:

所述项目投票阶段为S300区块链Web系统中未参与问题的用户对网格长用户发布的项目公开信息进行合理度评定并投票，在投票截止日期后的投票不计入结果，将最终结果与合理标准进行对比。若结果为不合理则触发投票质疑机制，核查部门进行裁决后结束此项目；若为合理则此项目结束。项目结束后，网格长用户按照事先达成的协定进行Credit证明的发放。In the project voting stage, users who did not participate in the issue in the S300 blockchain web system evaluate and vote on the reasonableness of the project public information released by grid long users. The votes after the voting deadline will not be included in the results, and the final results Compare with reasonable standards. If the result is unreasonable, the voting challenge mechanism will be triggered, and the verification department will end the project after making a ruling; if it is reasonable, the project will end. After the end of the project, the long grid users will issue the Credit certificate according to the agreement reached in advance.

上述最终结果计算时，按照区块链Web系统用户所拥有的CS总量为用户赋予不同的投票系数计入总结果。When calculating the final result above, according to the total amount of CS owned by the users of the blockchain web system, different voting coefficients are assigned to the users and included in the total result.

上述投票质疑机制为核查部门对投票结果为不合理的项目进行审查、裁决，若审查为合理，则投票结果修正为合理；若审查结果为不合理，则核查部门将扣除部分此项目工作部门和网格长被冻结的CTN作为此次投票奖励。The above voting challenge mechanism is for the verification department to review and adjudicate the project whose voting result is unreasonable. If the review is reasonable, the voting result will be revised to be reasonable; if the review result is unreasonable, the verification department will deduct part of the project work department and The CTN whose grid length is frozen will be rewarded for this vote.

上述投票奖励为将CTN发放给投票选择与最终合理结果一致的区块链Web系统用户，CTN发放时按照用户拥有的CS总量发放，若用户参与投票活动且投票结果经常错误，投票选择错误次数大于系统设定的阈值将会受到扣除CTN的惩罚。The above voting reward is to distribute CTN to the users of the blockchain web system who have the same final and reasonable voting results. CTN is issued according to the total amount of CS owned by the user. If the user participates in the voting activities and the voting results are often wrong, the number of wrong voting selections will be made. Anything larger than the threshold set by the system will be penalized by deducting CTN.

上述系统进行Credit证明的发放是在项目结束后，按照协定将现有工作部门用户冻结的CTN和网格长用户冻结的CTN一起重新加入到工作部门用户的CTN中，并为工作部门发放完成任务协定中CTN数量等额的F-CS。为网格长用户增加此次项目使用CTN等额的F-CS，并为网格长用户增加额外的F-CS作为奖励，奖励的F-CS数量按此项目使用的CTN数量而定。提交问题并进行评价的居民在完整参与本项目后，可获得S500居民系统内的F-CS，获取的F-CS可以用于社区生活缴费的减免。The issuance of the Credit certificate by the above system is to re-add the CTN frozen by the existing work department users and the CTN frozen by the grid long user to the CTN of the work department user according to the agreement after the project ends, and issue the completed tasks for the work department. F-CS equal to the number of CTNs in the agreement. For the long grid users, the project will use the same amount of CTN F-CS, and add additional F-CS as a reward for the long grid users. The number of F-CS rewarded is determined by the number of CTNs used in this project. Residents who submit questions and make evaluations can obtain F-CS in the S500 resident system after fully participating in the project, and the obtained F-CS can be used to reduce or exempt community living fees.

上述对居民进行社区生活缴费减免的费用由本次网格长用户立项所提供的部分手续费提供。The above-mentioned fee reduction and exemption for residents' community living payment is provided by part of the handling fee provided by this grid long user project.

上述为工作部门发放F-CS时，若协定CTN数量全部用完，则为工作部门发放等额的F-CS，若工作完成后协定CTN数量未全部使用，则将工作中使用的CTN转化为等额的F-CS，把未使用的CTN转化为等额的F-CS并根据未使用的CTN数量给与部分F-CS作为奖励。When the above-mentioned F-CS is issued for the work department, if the agreed number of CTNs is used up, the same amount of F-CS will be issued to the work department. For the F-CS, the unused CTN is converted into an equal amount of F-CS and part of the F-CS is given as a reward according to the number of unused CTNs.

上述冻结CTN加入到工作部门的CTN的过程中，工作部门用户需要自己向系统提交CTN恢复请求，网格长用户向系统提交CTN发放请求。具体而言，项目结束后，网格长用户按照协定发放CTN至工作部门用户，并且获取工作部门用户节省未使用的CTN；工作部门用户通过将CTN转化为CTD支付外部资源经费；In the process of adding the frozen CTN to the CTN of the work department, the user of the work department needs to submit a CTN recovery request to the system, and the long grid user submits a CTN issuance request to the system. Specifically, after the end of the project, the long grid users will issue CTNs to the users of the work department according to the agreement, and obtain the users of the work department to save the unused CTN; the users of the work department will pay for external resources by converting the CTNs into CTDs;

若网格长用户发放的CTN数量与先前达成协定的CTN数量不同，工作部门可以提起协定质疑。If the number of CTNs issued by the long grid users is different from the number of CTNs previously agreed upon, the working department can challenge the agreement.

上述协定质疑为在工作结束并且经投票机制后，网格长用户未按原来达成的协定进行CTN发放，工作部门向核查部门提交质疑申请和质疑的CTN数量。核查部门接受申请后，系统自动冻结网格长用户和工作部门用户的质疑数量的CTN，核查部门根据网格长用户和工作部门用户提供的最新协定记录综合投票机制结果与发放记录进行验证，并对验证结果的过错方进行惩罚。(此处协定质疑涉及的两方可提供协定记录之外的证明，文本数据可直接提供上链，文件数据利用IPFS进行存储并将存储反馈提供上链)。The question of the above agreement is that after the end of the work and the voting mechanism, the long grid users did not issue CTNs according to the original agreement, and the working department submitted the application for questioning and the number of CTNs questioned to the verification department. After the verification department accepts the application, the system automatically freezes the number of CTNs questioned by the grid long user and the work department user. Penalize the wrong party of the verification result. (The two parties involved in the agreement questioning here can provide proofs other than the agreement records, text data can be directly provided on the chain, and file data can be stored using IPFS and the storage feedback can be provided on the chain).

上述对过错方进行惩罚为将进入质疑环节冻结的过错方CTN作为奖励发放给最终质疑结果的正确方。The above-mentioned punishment for the faulty party is to issue the CTN of the faulty party who has entered the questioning link to be frozen as a reward to the correct party with the final questioning result.

具体地，在本实施例中：Specifically, in this embodiment:

向区块链中执行的写入类操作在写入数据前要对数据进行分析，将首次保存字段进行编码保存，然后执行写入类操作。Before writing data, the write operation to the blockchain needs to analyze the data, encode and save the first save field, and then perform the write operation.

上述区块链写入类操作包括：项目公布、协定建立、Credit发放、Credit更新、质疑记录、投票合约、密码重置。The above blockchain writing operations include: project announcement, agreement establishment, Credit issuance, Credit update, challenge record, voting contract, and password reset.

上述分析判断是否包含新字段，编码保存新字段是通过调用新增字段编码智能合约，遍历查询已保存的字段列表中是否有输入的字段名称，如果没有，将输入字段进行编码并保存至链下数据库的FieldCode表与区块链中。编码规则为字段类型编号(01：int；02：string；03：bool；04：float；05：double；06：time)与字段序号(“已有字段数量+1”)拼接生成。The above analysis judges whether new fields are included, and the encoding and saving of new fields is done by calling the new field encoding smart contract, traversing and querying whether there is an input field name in the saved field list, if not, encoding the input field and saving it to the off-chain The FieldCode table of the database is in the blockchain. The encoding rule is generated by concatenating the field type number (01: int; 02: string; 03: bool; 04: float; 05: double; 06: time) and the field serial number ("Number of existing fields + 1").

区块链将接收到的消息内容上链编码操作是指将收到的JSON格式的消息内容进行解析，获取到解析后每一个字段名称对应的编码，将所有的字段名称对应的编码与字段名称对应的值进行拼接得到用于上链记录数据信息的字符串。将获得的字符串进行上链存储。The operation of the blockchain to upload the received message content to the chain means to parse the received message content in JSON format, obtain the code corresponding to each field name after parsing, and combine the codes corresponding to all field names with the field names. The corresponding values are spliced to obtain a string for recording data information on the chain. Store the obtained string on the chain.

上述对上链消息建立查询索引后存储到链下数据库是指在执行过数据信息上链存储的操作后，将该数据的对象名称与每一个字段的字段键值分别拼接，并与本次操作所存储的区块链保存键一起存储到链下数据库的对象数据表中。The above-mentioned establishment of a query index for on-chain messages and storage in the off-chain database means that after performing the operation of data information on-chain storage, the object name of the data and the field key value of each field are spliced separately, and combined with this operation The stored blockchain save key is stored together into the object data table of the off-chain database.

上述FieldCode表和查询对象表设计如图5与表5所示：The design of the above FieldCode table and query object table is shown in Figure 5 and Table 5:

表5table 5

在查询项目、查询公开信息、查询工作完成信息、查询用户Credit证明数量等操作的时候需要进行区块链查询操作，所述区块链查询操作是获取符合查询条件的信息所保存的区块链保存键，利用保存键获取区块链上保存的信息后对信息进行解码验证，并返回符合查询条件的信息列表。主要流程如图9所示，主要流程时序图如图10所示，具体步骤如下：When querying projects, querying public information, querying work completion information, querying the number of user credit certificates, etc., a blockchain query operation is required. The blockchain query operation is to obtain the information that meets the query conditions and save the blockchain. Save key, use the save key to obtain the information saved on the blockchain, decode and verify the information, and return a list of information that meets the query conditions. The main process is shown in Figure 9, and the main process sequence diagram is shown in Figure 10. The specific steps are as follows:

Step1：上述获取符合查询条件的区块链保存键过程为：将查询对象与查询条件(查询字段名称、查询字段值)进行拼接获得查询关键字，通过获得的查询关键字在链下数据库中对应的查询对象表中进行检索，获取查询关键字所对应的区块链保存键。Step1: The above process of obtaining the blockchain storage key that meets the query conditions is as follows: splicing the query object and the query conditions (query field name, query field value) to obtain the query keyword, and the obtained query keyword corresponds to the off-chain database Search in the query object table of the query object table to obtain the blockchain storage key corresponding to the query keyword.

Step2：获得区块链保存键后利用数据查询智能合约读取对应区块保存的上链编码信息。Step2: After obtaining the blockchain storage key, use the data query smart contract to read the on-chain coding information stored in the corresponding block.

Step3：将获得区块信息进行解码操作，解码操作的具体步骤为：Step3: Perform decoding operation on the obtained block information. The specific steps of decoding operation are:

(1)获取区块保存的上链编码信息后对获取的信息进行切割，得到本条上链信息所包含的每一个字段的字段编码与对应字段值的键值对。(1) After obtaining the on-chain coding information stored in the block, cut the obtained information, and obtain the key-value pair of the field code and the corresponding field value of each field contained in the on-chain information.

(2)通过每个字段的字段编码获取相对应的字段名称，将字段名称与对应字段值组合成K-V键值对。(2) Obtain the corresponding field name through the field code of each field, and combine the field name and the corresponding field value into a K-V key-value pair.

(3)将验证通过的信息新组合成的所有K-V键值对拼接，并序列化为JSON格式。将从不同区块链保存键中获取的全部JSON格式的信息添加至符合查询条件的信息列表中，最后返回此信息列表。(3) Splicing all K-V key-value pairs newly assembled from the verified information, and serializing them into JSON format. Add all JSON-formatted information obtained from different blockchain storage keys to the list of information that meets the query conditions, and finally return this information list.

Step4：将查询字段名称所对应的K-V键值对的字段值与查询字段值进行对比验证，若一致则验证通过。若不一致则验证失败，返回错误。Step4: Compare and verify the field value of the K-V key-value pair corresponding to the query field name with the query field value. If they are consistent, the verification is passed. If it is inconsistent, the verification fails and an error is returned.

本发明提出的基于区块链的智慧社区问题处理方法在可以实现社区问题处理流程数据安全、可靠存储的同时，还可以提升系统的灵活性和外部可交互性。The blockchain-based smart community problem processing method proposed by the present invention can improve the flexibility and external interactivity of the system while realizing the safe and reliable storage of the community problem processing process data.

下面以第一社区环境治理问题为例，介绍本系统的问题处理的流程，流程如图11所示，主要步骤如下：The following takes the first community environmental governance problem as an example to introduce the problem handling process of this system. The process is shown in Figure 11. The main steps are as follows:

Step1：第一社区居民用户登录居民系统，将社区内环境问题进行上传，供第一社区网格长用户查看。Step1: Resident users of the first community log in to the resident system, and upload the environmental problems in the community for viewing by the long-term users of the first community grid.

Step2：第一社区网格长用户登录居民系统，查看第一社区居民用户提报的环境问题，对环境问题进行分析后批准此环境问题立项处理。Step 2: The long user of the first community grid logs in to the resident system, checks the environmental problems reported by the residents of the first community, analyzes the environmental problems, and approves the project approval of this environmental problem.

Step3：第一社区网格长用户批准环境问题立项后，通过居民系统将问题信息发送至消息队列，由区块链Web系统接收。Step3: After the first community grid long user approves the environmental issue, the issue information is sent to the message queue through the resident system and received by the blockchain web system.

Step4：第一社区网格长用户利用区块链Web系统登录密码登录系统，对接收到的环境问题进行分析并给出此次治理环境问题所用的CTN数量(此处为使用20个CTN)，将环境问题治理要求等信息和CTN数量进行绑定。Step4: The long user of the first community grid uses the blockchain Web system to log in to the system with a password, analyzes the environmental problems received and gives the number of CTNs used to manage environmental problems this time (here, 20 CTNs are used), Bind information such as environmental governance requirements to the number of CTNs.

Step5：问题信息中包含视频、图片、文档等描述文件，第一社区网格长用户将这些大型文件存储在IPFS中，将存储反馈信息与Step4中信息一起绑定。Step5: The question information contains description files such as videos, pictures, documents, etc. The first community grid long user stores these large files in IPFS, and binds the storage feedback information with the information in Step4.

Step6：将第一社区网格长用户上传的第一社区环境问题信息发送到S300区块链Web系统。Step6: Send the first community environmental problem information uploaded by the first community grid long user to the S300 blockchain web system.

Step7：S300区块链Web系统调用智能合约将接收到的环境问题的数据信息保存至主链。Step7: The S300 blockchain web system calls the smart contract to save the received data information of environmental issues to the main chain.

Step8：第一社区网格长用户发布的环境治理问题在S300区块链Web系统向所有工作部门公开，数据通过区块链Web系统进行展示。Step8: The environmental governance issues published by the long users of the first community grid are disclosed to all working departments in the S300 blockchain web system, and the data is displayed through the blockchain web system.

Step9：区块链Web系统中用户查询并分析认领此次发布的第一社区环境治理问题的部分或全部工作。Step9: Users in the blockchain web system query, analyze and claim part or all of the work of the first community environmental governance issue released this time.

Step10：协调部门用户决定认领协调居民协助治理的工作，与第一社区网格长用户建立协定，认领协调居民协助治理的工作和4个CTN；治理部门与治理部门X同时决定认领环境治理工作，并与第一社区网格长用户建立协定，分别需要14个和15个CTN进行工作。Step10: The user of the coordination department decides to claim the work of coordinating residents to assist in governance, establish an agreement with the long user of the first community grid, and claim the work of coordinating residents to assist in governance and 4 CTNs; the governance department and governance department X also decide to claim the environmental governance work, And establish an agreement with the first community grid long user, which requires 14 and 15 CTNs to work respectively.

Step11：第一社区网格长用户与协调部门用户就使用4个CTN协调居民协助治理的工作达成协定一致；第一社区网格长用户分别与治理部门和治理部门X进行重新协定(重新执行Step10中环境治理工作部分内容)，最终以12个CTN进行第一社区环境治理工作与治理部门达成协定一致。Step11: The first community grid long user and the coordination department user reach an agreement on the use of 4 CTNs to coordinate residents to assist in governance; the first community grid long user re-agrees with the governance department and governance department X respectively (re-execute Step 10 Part of the environmental governance work in the middle), and finally reached an agreement with the governance department to carry out the environmental governance work of the first community with 12 CTNs.

Step12：Step10和Step11中建立并达成协定一致的全部过程数据由协定双方(第一社区网格长用户与协调部门、第一社区网格长用户与治理部门)进行双重签名后发送给S300区块链Web系统侧链。Step12: All process data established and agreed in Step10 and Step11 are double-signed by both parties (the first community grid long user and the coordination department, the first community grid long user and the governance department) and sent to block S300 Chain web system side chain.

Step13：S300区块链Web系统调用智能合约将接收到的数据保存至侧链。Step13: The S300 blockchain web system calls the smart contract to save the received data to the side chain.

Step14：系统冻结协调部门用户4个CTN、治理部门用户12个CTN，第一社区网格长用户两次分别冻结4个、12个CTN，协调部门用户和治理部门用户处理认领的工作。Step14: The system freezes 4 CTNs for users in the coordination department and 12 CTNs for users in the governance department. The first community gridlong user freezes 4 CTNs and 12 CTNs twice, respectively, to coordinate the work of users in the coordination department and users in the governance department to process claims.

Step15：协调部门用户和治理部门用户认领工作处理结束，将处理结果中的视频、图片、文档等描述文件存储到IPFS中，将存储反馈数据与其他处理结果文本数据绑定，上传到区块链保存，协调部门用户共使用4个CTN，治理部门共使用10个CTN，多余认领的2个CTN将返回给第一社区网格长用户。Step15: The user of the coordination department and the user of the management department have finished the process of claiming the work. Store the description files such as videos, pictures, and documents in the processing results in IPFS, and bind the stored feedback data with other text data of the processing results, and upload them to the blockchain Users in the storage and coordination departments use a total of 4 CTNs, and the governance department uses a total of 10 CTNs. The 2 CTNs claimed will be returned to the first community grid long user.

Step16：第一社区网格长用户将本次第一社区环境治理过程可公开数据在区块链Web系统中进行公布，由区块链Web系统中其他用户进行投票。Step16: The long users of the first community grid will publish the open data of the first community environmental governance process in the blockchain web system, and other users in the blockchain web system will vote.

Step17：投票结果合理度为95％以上，第一社区网格长用户将事先冻结的12个CTN发放给治理部门用户，将事先冻结的4个CTN发放给协调部门用户(此处实际情况为第一社区网格长用户进行恶意操作，只向协调部门用户发放3个CTN)。系统将事先冻结的协调部门用户和治理部门用户的CTN解冻，向第一社区网格长用户发放与20CTN等额的F-CS作为奖励，向协调部门用户发放3个CTN等额的F-CS作为奖励，向治理部门发放13个CTN等额的F-CS作为奖励(多发放的1个作为治理部门用户节省2个CTN的额外奖励)。Step17: The voting result is more than 95% reasonable. The first community grid long user distributes the 12 CTNs frozen in advance to the users of the governance department, and the 4 CTNs that are frozen in advance to the users of the coordination department (the actual situation here is the first A long-term user of the community grid conducts malicious operations andonly issues 3 CTNs to users of the coordination department). The system will unfreeze the CTNs of users in the coordination department and users in the governance department that have been frozen in advance, and distribute F-CS equal to 20 CTN to the first community grid long users as rewards, and distribute F-CS equal to 3 CTNs to users of the coordination department as rewards , 13 CTN equivalent F-CS will be issued to the governance department as a reward (the extra one will be issued as an additional reward for users of the governance department to save 2 CTNs).

Step18：协调部门用户就1个CTN提起质疑。Step18: The user of the coordination department raises a question about a CTN.

Step19：核查部门收到质疑请求，并进行质疑处理，系统分别自动冻结第一社区网格长用户和协调部门2个CTN，其中，上述2个CTN中一个为协调部门用户提出的质疑数量的CTN,另一个为质疑环节惩罚需要的CTN，第一社区网格长用户与协调部门用户分别通过S300区块链Web系统从区块链侧链读取最新版的协定并提交到核查部门。Step19: The verification department receives the challenge request and handles the challenge. The system automatically freezes the 2 CTNs of the first community grid long user and the coordination department respectively. One of the above 2 CTNs is the CTN of the number of questions raised by the users of the coordination department. , Another CTN required for the punishment of the questioning link, the first community grid long user and the coordination department user respectively read the latest version of the agreement from the blockchain side chain through the S300 blockchain web system and submit it to the verification department.

Step20：核查部门依据协定进行裁决，过错方为第一社区网格长用户，将质疑环节事先冻结的第一社区网格长用户和协调部门用户共4个CTN发放给协调部门用户并由系统向协调部门用户发放1个CTN等额的F-CS补充奖励。Step 20: The verification department makes a ruling according to the agreement. The fault is the first community grid user. The first community grid user and the coordination department user, which have been frozen in advance in the questioning process, are issued a total of 4 CTNs to the coordination department user. The users of the coordination department will issue a supplementary reward of F-CS equal to 1 CTN.

Step21：第一社区网格长用户和协调部门用户执行裁决结果。Step 21: The first community grid long user and the coordinating department user execute the adjudication result.

本次治理过程中，治理部门调用了外部资源，请求家政公司以5个CTN等额经费的价格处理部分环境问题(付费方式为分3期共6个月)，工作结束后治理部门向区块链Web系统进行拨款申请，由区块链Web系统按治理部门提交方案，分期将5个CTN等额经费兑现给外部资源(家政公司)。During this governance process, the governance department called external resources and requested the housekeeping company to deal with some environmental issues at the price of 5 CTNs (the payment method is divided into 3 phases for a total of 6 months). The web system applies for grants, and the blockchain web system submits the plan according to the governance department, and cashes out 5 CTN equivalent funds to external resources (housekeeping companies) in installments.
