背景技术Background technique
当前的生产生活中，经常需要调用数据，可调用的数据是否真实，不可而知，调用的数据格式是否适用于当前环境，不可而知，从而出现数据可信度低、可用程度差(需要进行进一步转换格式等)等问题。尤其在对数据真实性要求程度高的应用场景，例如贷款核批等场景中，现有技术一般是从数据库中调用相应数据，调用的数据仅以单一的形式呈现给调用方，不能适应不同的调用需求，同时数据库中的相应数据若被偷偷篡改，将导致调用方做出错误的结论。因此现有技术无法解决上述数据安全性差、同时数据直接使用程度差等问题。In the current production and life, it is often necessary to call data. Whether the callable data is real or not is unknown, and whether the callable data format is suitable for the current environment is unknown, resulting in low data reliability and poor usability (need to Further conversion format, etc.) and other issues. Especially in application scenarios that require a high degree of data authenticity, such as loan approval and other scenarios, the existing technology generally calls the corresponding data from the database, and the called data is only presented to the caller in a single form, which cannot adapt to different applications. Call requirements, and if the corresponding data in the database is secretly tampered with, it will lead the caller to make a wrong conclusion. Therefore, the prior art cannot solve the aforementioned problems of poor data security and poor direct use of data.

为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
参照图1，本申请实施例提供一种基于区块链的数据保存方法，应用于数据保存终端，包括：Referring to Figure 1, the embodiment of the present application provides a blockchain-based data storage method, which is applied to a data storage terminal, including:
S1、接收对指定数据的数据保存指令，其中所述数据保存指令记载了指定数据的类型，所述数据保存终端是预先搭建的区块链网络中的一个区块链节点；S1. Receive a data storage instruction for specified data, wherein the data storage instruction records the type of specified data, and the data storage terminal is a blockchain node in a pre-built blockchain network;

S4、将所述初始数据发送给具有审核权限的区块链节点；S4. Send the initial data to the blockchain node with audit authority;
S5、接收所述具有审核权限的区块链节点的反馈信息，并判断所述反馈信息是否满足预设的数据保存条件；S5. Receive feedback information from the blockchain node with audit authority, and judge whether the feedback information satisfies a preset data storage condition;
S6、若所述反馈信息满足预设的数据保存条件，则将所述初始数据记录入所述区块链网络。S6. If the feedback information satisfies the preset data storage condition, record the initial data into the blockchain network.
如上述步骤S1所述，接收对指定数据的数据保存指令，其中所述数据保存指令记载了指定数据的类型，所述数据保存终端是预先搭建的区块链网络中的一个区块链节点。本中指定数据可为任意数据，例如虚拟币交易、生产数据、贸易数据、金融数据、贷款审批数据、风控数据等数据。所述数据保存指令是指指示将所述指定数据记录在所述区块链中的指令。预先搭建的区块链网络可以是公有链、联盟链或者私有链，优选联盟链。区块链节点可包括任意终端，例如各银行中的计算机终端。所述区块链网络的共识机制可为任意共识机制，例如工作量证明机制、权益证明机制、指定共识机制(DPOS)等，优选采用股份授权证明的共识机制。其中，所述指定数据的类型可为任意方式分类的类型，例如为风控数据、生产数据、贸易数据等，当然，还可以包括任意不同分类方式分成的数据类型。不同类型的指定数据采用的数据格式不同。As described in the above step S1, a data storage instruction for the specified data is received, wherein the data storage instruction records the type of the specified data, and the data storage terminal is a blockchain node in the pre-built blockchain network. The data specified in this document can be any data, such as virtual currency transactions, production data, trade data, financial data, loan approval data, risk control data and other data. The data saving instruction refers to an instruction indicating to record the specified data in the block chain. The pre-built blockchain network can be a public chain, alliance chain or private chain, preferably alliance chain. Blockchain nodes can include arbitrary terminals, such as computer terminals in banks. The consensus mechanism of the blockchain network can be any consensus mechanism, such as workload proof mechanism, equity proof mechanism, designated consensus mechanism (DPOS), etc., preferably adopting the consensus mechanism of share authorization certificate. Wherein, the type of the specified data can be classified in any way, such as risk control data, production data, trade data, etc. Of course, it can also include any data types classified by different classification methods. Different types of specified data adopt different data formats.
如上述步骤S2所述，从预设的多个数据模板中调取与所述指定数据的类型对应的初始数据模板。由于不同类型的指定数据采用的数据格式不同，因此通过从预设的多个数据模板中调取与所述指定数据的类型对应的初始数据模板，可以及早获取准确的数据格式，提高形成数据的速度，免去了从零开始形成数据的步骤。进一步地，所述初始数据模板由数据框架模板和至少一个数据子模板构成，从而更进一步地利用可编辑可组的分离式数据的特性，达到更高效率生成更有准确的数据。As described in step S2 above, an initial data template corresponding to the type of the specified data is called from a plurality of preset data templates. Since different types of specified data adopt different data formats, by calling the initial data template corresponding to the type of the specified data from the preset multiple data templates, the accurate data format can be obtained early, and the efficiency of forming data can be improved. Speed, eliminating the step of forming data from scratch. Further, the initial data template is composed of a data frame template and at least one data sub-template, so as to further utilize the characteristics of editable and groupable separated data to achieve higher efficiency and generate more accurate data.
如上述步骤S3所述，将预先准备好的数据填入所述初始数据模板中，得到初始数据。由前述可知，初始数据模板是针对性生成的，因此预先准备好的数据是与初始数据模板相匹配的，将预先准备好的数据相应填入所述初始数据模板中，即可得到初始数据。As described in step S3 above, the pre-prepared data is filled into the initial data template to obtain initial data. As can be seen from the foregoing, the initial data template is generated in a targeted manner, so the pre-prepared data matches the initial data template, and the pre-prepared data is correspondingly filled into the initial data template to obtain the initial data.
如上述步骤S4所述，将所述初始数据发送给具有审核权限的区块链节点。根据预先约定的不同，具有审核权限的区块链节点也不同。例如当采用股份授权证明的共识机制时，所述具有审核权限的区块链节点即为由所有区块链节点投选出的受托区块链节点。这些具有审核权限的区块链节点审核所述初始数据，进而决定所述初始数据能否加入所述区块链网络。As described in step S4 above, the initial data is sent to the blockchain node with audit authority. According to the pre-agreement, the blockchain nodes with audit authority are also different. For example, when the consensus mechanism of share authorization certificate is adopted, the blockchain node with audit authority is the entrusted blockchain node voted by all blockchain nodes. These blockchain nodes with audit authority audit the initial data, and then decide whether the initial data can be added to the blockchain network.
如上述步骤S5所述，接收所述具有审核权限的区块链节点的反馈信息，并判断所述反馈信息是否满足预设的数据保存条件。所述反馈信息可以是任意形式的能够反应初始数据是否审核通过的信息。例如，所述反馈信息包括审核通过或者审核未通过。判断所述反馈信息是否满足预设的数据保存条件的过程包括：判断所述审核通过的反馈信息的数量是否大于预设的数量阈值；若所述审核通过的反馈信息的数量大于预设的数量阈值，则判定反馈信息满足预设的数据保存条件。其中预设的数量阈值例如为所述具有审核权限的区块链节点数量的一半加一。As described in step S5 above, the feedback information from the blockchain node with audit authority is received, and it is judged whether the feedback information satisfies the preset data storage condition. The feedback information may be any form of information that can reflect whether the initial data is approved or not. For example, the feedback information includes whether the review is passed or the review is not passed. The process of judging whether the feedback information satisfies the preset data storage conditions includes: judging whether the number of the feedback information passed the review is greater than a preset quantity threshold; if the number of the feedback information passed the review is greater than the preset number threshold, it is determined that the feedback information meets the preset data storage conditions. The preset quantity threshold is, for example, half of the number of blockchain nodes with audit authority plus one.
如上述步骤S6所述，若所述反馈信息满足预设的数据保存条件，则将所述初始数据记录入所述区块链网络。若所述反馈信息满足预设的数据保存条件，表明所述初始数据是正确的，是允许加入区块链的。据此，将所述初始数据记录入所述区块链网络。As described in step S6 above, if the feedback information satisfies the preset data storage condition, then record the initial data into the blockchain network. If the feedback information satisfies the preset data storage conditions, it indicates that the initial data is correct and is allowed to be added to the blockchain. Accordingly, the initial data is recorded into the blockchain network.
在一个实施方式中，所述初始数据模板由数据框架模板和至少一个数据子模板构成，所述从预设的多个数据模板中调取与所述指定数据的类型对应的初始数据模板的步骤S2，包括：In one embodiment, the initial data template is composed of a data frame template and at least one data sub-template, and the step of calling an initial data template corresponding to the specified data type from a plurality of preset data templates S2, including:
S201、根据所述指定数据的类型，依据预设的数据类型与模板的对应关系，获取预设的多个数据框架模板与多个数据子模板；S201. Acquire multiple preset data frame templates and multiple data sub-templates according to the type of the specified data and according to the preset correspondence between data types and templates;
S202、获取数据保存终端选择的数据框架模板与数据子模板，并将所述数据保存终端选择的数据框架模板与数据子模板组合成为所述初始数据模板；S202. Obtain the data frame template and data sub-template selected by the data storage terminal, and combine the data frame template and data sub-template selected by the data storage terminal into the initial data template;
S203、调取所述初始数据模板。S203. Call the initial data template.
如上所述，实现了从预设的多个数据模板中调取与所述指定数据的类型对应的初始数据模板。本实施方式采用的所述初始数据模板由数据框架模板和至少一个数据子模板构成，从而使得数据可利用组合预设的模板的方式形成，使数据的生成更为快捷，并能针对性地生成适宜的数据。由于不同数据需要的具体要求不同，因此数据的格式、布局(框架)等各方面都不尽相同。通过将数据分解为框架和细节部分，再针对性地预先设计有框架模板与子模板(细节部分模板)，当需要指定数据的模板时，只需从已有的框架模板与子模板中选择，再组合起来，即可形成所述初始数据模板。其中当指定数据为特定操作审批数据时，数据子模板例如为抵押物子模板(包括抵押物相关的字段，包括抵押物名称字段、估值字段、抵押历史字段等)。As described above, it is realized that an initial data template corresponding to the type of the specified data is called from a plurality of preset data templates. The initial data template used in this embodiment is composed of a data frame template and at least one data sub-template, so that data can be formed by combining preset templates, making data generation faster and targeted appropriate data. Due to the different specific requirements of different data, the format, layout (frame) and other aspects of the data are different. By decomposing the data into frame and detail parts, and then pre-designing frame templates and sub-templates (detail part templates), when you need to specify a template for data, you only need to choose from the existing frame templates and sub-templates, Combined again, the initial data template can be formed. Wherein when the specified data is specific operation approval data, the data sub-template is, for example, a mortgage sub-template (including fields related to mortgages, including mortgage name fields, valuation fields, mortgage history fields, etc.).
在一个实施方式中，所述区块链网络包括指定区块链节点，所述将预先准备好的数据填入所述初始数据模板中，得到初始数据的步骤S3,包括：In one embodiment, the block chain network includes a designated block chain node, and the step S3 of filling the pre-prepared data into the initial data template and obtaining the initial data includes:
S301、接收从指定区块链节点发送的特定数据，其中所述特定数据包括特定对象的身份信息、教育经历或者是否属于黑名单的信息；S301. Receive specific data sent from a designated blockchain node, wherein the specific data includes the identity information, educational experience, or information of whether a specific object belongs to a blacklist;
S302、将所述特定数据填入所述初始数据模板中，得到初始数据。S302. Fill the specific data into the initial data template to obtain initial data.
如上所述，实现了将预先准备好的数据填入所述初始数据模板中，得到初始数据。本实施方式采用从指定区块链节点发送的特定数据作为数据，并将在后续流程中加入区块链中，从而利用区块链的数据难以篡改的特性，保证特定数据真实有效，以使特定相关的程序有真实的数据可依靠。其中所述特定数据包括特定对象的身份信息、教育经历或者是否属于黑名单的信息，可供特定操作审批等流程进行调用。将所述特定数据填入所述初始数据模板中，得到初始数据的方式包括：分别提取从指定区块链节点发送的特定数据，以得到不同字段对应的数据内容；将所述数据内容填入所述初始数据模板的相应字段中，得到初始数据。其中所述指定区块链节点可以为任意区块链节点，例如为银行区块链节点。其中所述特定数据例如为风控数据等。As mentioned above, it is realized that the pre-prepared data is filled into the initial data template to obtain the initial data. This embodiment adopts the specific data sent from the specified blockchain node as data, and will add it to the blockchain in the subsequent process, so as to make use of the characteristics of blockchain data that are difficult to tamper with, to ensure that the specific data is true and effective, so that the specific The relevant programs have real data to rely on. The specific data includes the identity information, educational experience, or blacklist information of the specific object, which can be used for procedures such as approval of specific operations. Filling the specific data into the initial data template, and obtaining the initial data includes: respectively extracting the specific data sent from the specified blockchain node to obtain the data content corresponding to different fields; filling the data content into The initial data is obtained in the corresponding field of the initial data template. Wherein the specified blockchain node can be any blockchain node, such as a bank blockchain node. Wherein the specific data is, for example, risk control data and the like.
在一个实施方式中，所述区块链网络采用指定共识机制，所述接收所述具有审核权限的区块链节点的反馈信息，并判断所述反馈信息是否满足预设的数据保存条件的步骤S5，包括：In one embodiment, the block chain network adopts a designated consensus mechanism, the step of receiving the feedback information from the block chain node with audit authority, and judging whether the feedback information satisfies the preset data storage conditions S5, including:
S501、接收基于所述指定共识机制而投选出的多个受托区块链节点的反馈信息，其中所述受托区块链节点具有审核权限，所述反馈信息包括审核通过或者审核未通过；S501. Receive feedback information from a plurality of entrusted blockchain nodes voted based on the specified consensus mechanism, wherein the entrusted blockchain nodes have audit authority, and the feedback information includes whether the audit is passed or the audit is not passed;
S502、统计审核通过的反馈信息的数量，并判断所述审核通过的反馈信息的数量是否大于预设的数量阈值；S502. Count the number of feedback information that has passed the review, and determine whether the number of feedback information that has passed the review is greater than a preset quantity threshold;

如上所述，实现了接收所述具有审核权限的区块链节点的反馈信息，并判断所述反馈信息是否满足预设的数据保存条件。本实施方式中的区块链网络采用指定共识机制(例如股份授权证明机制)的共识机制，从而减少审核需要的时间。其中，股份授权证明机制类似于董事会投票，就是区块链节点会进行投票，从而投选出一部分数量的节点(受托区块链节点)，所述受托区块链节点代理所有区块链节点进行验证审核工作，从而不需要每个区块链节点都进行验证审核。所述反馈信息包括审核通过或者审核未通过。通过统计审核通过的反馈信息的数量，并判断所述审核通过的反馈信息的数量是否大于预设的数量阈值，若所述审核通过的反馈信息的数量大于预设的数量阈值，则判定反馈信息满足预设的数据保存条件；若不大于预设的数量阈值，则判定反馈信息不满足预设的数据保存条件。具体的数量阈值例如可设为所述具有审核权限的区块链节点数量的一半加一。As mentioned above, it is realized to receive the feedback information from the blockchain node with audit authority, and judge whether the feedback information satisfies the preset data storage condition. The blockchain network in this embodiment adopts a consensus mechanism of a specified consensus mechanism (such as a share authorization certificate mechanism), thereby reducing the time required for review. Among them, the share authorization certificate mechanism is similar to the voting of the board of directors, that is, the blockchain nodes will vote to select a part of the number of nodes (entrusted blockchain nodes), and the entrusted blockchain nodes will act on behalf of all blockchain nodes. Verification and audit work, so that each blockchain node does not need to conduct verification audits. The feedback information includes whether the review is passed or the review is not passed. By counting the number of feedback information passed through review, and judging whether the number of feedback information passed through review is greater than a preset number threshold, if the number of feedback information passed through review is greater than a preset number threshold, then determine the feedback information The preset data storage condition is satisfied; if it is not greater than the preset quantity threshold, it is determined that the feedback information does not meet the preset data storage condition. The specific quantity threshold can be set as half of the number of blockchain nodes with audit authority plus one, for example.

The data specified in this document can be any data, such as virtual currency transactions, production data, trade data, financial data, specific operation approval data, specific data and other data. The data saving instruction refers to an instruction indicating to record the specified data in the block chain. The pre-built blockchain network can be a public chain, alliance chain or private chain, preferably alliance chain. Blockchain nodes can include arbitrary terminals, such as computer terminals in banks. The consensus mechanism of the blockchain network can be any consensus mechanism, such as workload proof mechanism, equity proof mechanism, designated consensus mechanism (DPOS), etc., preferably adopting the consensus mechanism of share authorization certificate. Wherein, the type of the specified data may be classified in any manner, such as specific data, production data, trade data, etc., and of course, may also include any data types classified in different classification manners. Different types of specified data adopt different data formats.
如上述单元20所述，从预设的多个数据模板中调取与所述指定数据的类型对应的初始数据模板。由于不同类型的指定数据采用的数据格式不同，因此通过从预设的多个数据模板中调取与所述指定数据的类型对应的初始数据模板，可以及早获取准确的数据格式，提高形成数据的速度，免去了从零开始形成数据的步骤。进一步地，所述初始数据模板由数据框架模板和至少一个数据子模板构成，从而更进一步地利用可编辑可组的分离式数据的特性，达到更高效率生成更有准确的数据。As described in the above unit 20, an initial data template corresponding to the type of the specified data is called from a plurality of preset data templates.
