具体实施方式Detailed ways
信用闭环业务，是指对于一些从事与用户信用相关的服务的商家，可以将与用户信用相关的数据共享给信用评估方，由信用评估方基于这些信息生成用户信用记录，并对生成的用户信用记录进行维护；而信用评估方，可以基于维护的信用记录，以及自身的渠道来触达该用户，来反向监督和促进该用户积极履约，进而对维护的用户信用记录进行不断的积累，形成业务闭环的业务模式。Credit closed-loop business means that for some merchants engaged in services related to user credit, they can share data related to user credit with the credit evaluator, and the credit evaluator will generate user credit records based on these information, and evaluate the generated user credit The credit evaluator can reach the user based on the maintained credit record and its own channels to reversely supervise and promote the user's active performance of the contract, and then continuously accumulate the maintained user credit record to form a Business closed-loop business model.
而在本说明书中，则正是在信用闭环业务的业务背景下，提出的一种利用区块链技术来搭建一个信用记录共享平台，使得加入区块链的各个节点设备(商家)之间，可以依托于区块链的架构，以去中心化的方式来快捷的进行信用记录的共享的技术方案。In this specification, it is under the business background of the credit closed-loop business that a credit record sharing platform is proposed using blockchain technology, so that between each node device (merchant) that joins the blockchain, Relying on the blockchain architecture, it is a technical solution to quickly share credit records in a decentralized manner.
在实现时，区块链的运营方可以预先搭建一个由若干商家节点设备构成的区块链网络，并依托于该区块链网络来部署信用闭环业务，使得加入该区块链网络的商家节点设备，可以通过向区块链的分布式数据库(即分布式账本)中广播发布用户信用记录，来实现将用户信用记录在不同的商家中进行共享。When implementing, the operator of the blockchain can pre-build a blockchain network composed of several merchant node devices, and rely on the blockchain network to deploy credit closed-loop business, so that the merchant nodes that join the blockchain network The device can share user credit records among different merchants by broadcasting and publishing user credit records to the distributed database of the block chain (that is, the distributed ledger).
而对于区块链中的各个商家节点设备而言，可以收集当前记账周期内由各个商家节点设备广播发布至区块链，且经过各节点设备共同验证通过的用户信用记录，并基于收集到的用户信用记录来创建候选区块，然后基于上述区块链网络所支持的共识算法，在区块链中发起对该候选区块中所收录的用户信用记录进行共识处理，来“竞争”记账权限。For each merchant node device in the blockchain, it is possible to collect user credit records that are broadcast and published to the blockchain by each merchant node device in the current accounting cycle, and have been verified by each node device, and based on the collected Create a candidate block based on the user credit records of the above-mentioned blockchain network, and then initiate consensus processing on the user credit records included in the candidate block in the blockchain based on the consensus algorithm supported by the above-mentioned blockchain network to "compete" for record account permissions.
如果共识完成后，该商家节点设备被确定未记账节点，该商家节点设备可以将该候选区块作为最新的区块广播发布至该区块链网络，将该最新的区块加入到区块链的分布式数据库中。If the merchant node device is determined to be an unaccounted node after the consensus is completed, the merchant node device can broadcast the candidate block as the latest block to the blockchain network, and add the latest block to the block In the distributed database of the chain.
一方面，由于区块链具有历史可追溯性和不可篡改性，因此通过这种方式能够在区块链上真实的记录一段时间内产生的用户信用记录，并且所有用户信用记录均可以在区块链上进行追溯；而且，由于用户信用记录是由所有节点设备共同验证和维护，要进行用户信用记录的篡改，则需要控制大多数的节点设备才能做到，因此可以确保用户信用记录的公正性；On the one hand, due to the historical traceability and immutability of the blockchain, in this way, the user credit records generated within a period of time can be recorded on the blockchain, and all user credit records can be recorded in the block. It can be traced back on the chain; moreover, since user credit records are jointly verified and maintained by all node devices, to tamper with user credit records, it is necessary to control most of the node devices, so the fairness of user credit records can be ensured ;
另一方面，由于区块链中的各个节点设备产生的用户信用记录是共享的，各个节点设备通过在链上进行查询，就可以获得其它节点设备发布的用户信用记录，因此使得信用闭环可以不集中在其中一个节点设备，各个节点设备之间可以互相共享和监督；而且，在部署信用闭环业务时，触达用户的渠道也相应增多，多个节点设备可以通过使用链上的用户信用记录，对用户进行联合催缴、联合惩戒、以及联合激励等，来联合监督和促进用户积极履约。On the other hand, since the user credit records generated by each node device in the blockchain are shared, each node device can obtain the user credit records issued by other node devices by querying on the chain, so that the credit closed loop can not Concentrated on one of the node devices, each node device can share and supervise each other; moreover, when deploying the credit closed-loop business, the channels to reach users will increase accordingly, and multiple node devices can use the user credit records on the chain, Joint reminders, joint punishments, and joint incentives are carried out on users to jointly supervise and promote users' active performance of contracts.
下面通过具体实施例并结合具体的应用场景对本说明书进行描述。The specification is described below through specific embodiments and in combination with specific application scenarios.

在本说明书描述的区块链，具体可以包括任意类型的区块链网络。The blockchain described in this specification can specifically include any type of blockchain network.
例如，在示出的一种实施方式中，上述区块链具体可以是一个由若干商家节点设备组成的联盟链。各个商家可以依托于上述联盟链，将运营的一些与用户信用相关的线上或者线下服务所产生的用户信用记录，在区块链中进行发布，并收录在区块链的分布式数据库，以实现各个商家的用户信用记录的共享。For example, in one embodiment shown, the above-mentioned blockchain may specifically be a consortium chain composed of several merchant node devices. Each merchant can rely on the above-mentioned alliance chain to publish user credit records generated by some online or offline services related to user credit in the blockchain, and include them in the distributed database of the blockchain. In order to realize the sharing of user credit records of various merchants.
其中，在示出的一种实施方式中，上述区块链具体可以包括一个主链，以及与主链锚定的若干子链；Wherein, in one embodiment shown, the above-mentioned blockchain may specifically include a main chain and several sub-chains anchored to the main chain;
例如，以上述区块链为由若干商家节点设备构成的联盟链为例，可以基于作为联盟成员的商家的具体类型(比如商家所提供的服务的行业类型)，将该联盟链划分为一主链，以及与主链锚定的若干分别对应不同的商家类型的子链。For example, taking the above blockchain as an example of an alliance chain composed of several merchant node devices, the alliance chain can be divided into a main Chain, and several sub-chains anchored to the main chain corresponding to different types of merchants.
上述节点设备，可以包括能够作为成员加入至上述区块链的任意类型的电子设备；例如，上述电子设备可以包括但不限于是商家的PC终端、移动终端、服务器等。The above-mentioned node devices may include any type of electronic device that can be added to the above-mentioned blockchain as a member; for example, the above-mentioned electronic devices may include but not limited to PC terminals, mobile terminals, servers, etc. that are merchants.
上述信用记录，具体可以包括能够反映用户的信用状况的任意形式的数据记录；例如，与信用相关的服务的使用记录、履约记录、违约记录，等等。The credit records mentioned above may specifically include data records in any form that can reflect the user's credit status; for example, credit-related service usage records, contract performance records, breach of contract records, and so on.
上述记账周期，是指区块链上任意两个区块链接到区块链的分布式数据库上的时间间隔。相应的，上述当前记账周期，是指区块链的分布式数据库上的最新的区块链接到上述分布式数据库的时刻，至记账节点将下一个区块成功链接到上述分布式数据库的时刻之间的时间间隔。其中，上述记账周期的具体取值，可以由上述区块链的运营方基于实际的业务需求进行设定，在本说明书中不进行特别限定；例如，比特币的区块链网络的记账周期，为10分钟，每间隔10分钟产生一个新的区块。The above accounting cycle refers to the time interval between any two blocks on the blockchain linked to the distributed database of the blockchain. Correspondingly, the above-mentioned current bookkeeping cycle refers to the moment when the latest block on the distributed database of the blockchain is linked to the above-mentioned distributed database, until the bookkeeping node successfully links the next block to the above-mentioned distributed database. The time interval between moments. Among them, the specific value of the above-mentioned bookkeeping period can be set by the operator of the above-mentioned blockchain based on actual business needs, and is not specifically limited in this specification; for example, the bookkeeping of the Bitcoin blockchain network The period is 10 minutes, and a new block is generated every 10 minutes.
以下以上述目标节点设备为商家节点设备，上述区块链为由若干商家节点设备构成的联盟链为例对本说明书的技术方案进行详细说明。In the following, the technical solution of this specification will be described in detail by taking the above-mentioned target node device as a merchant node device and the above-mentioned blockchain as an alliance chain composed of several merchant node devices as an example.
请参见图2，图2为本说明书示出的一种联盟链的示意图。Please refer to Figure 2, which is a schematic diagram of a consortium chain shown in this specification.
如图2所示，区块链的运营方可以预先搭建一个由若干从事与用户信用相关的服务的商家组成的联盟链，而各个商家的商家节点设备，可以作为联盟链接入上述联盟链。As shown in Figure 2, the operator of the blockchain can pre-build an alliance chain composed of several merchants engaged in services related to user credit, and the merchant node equipment of each merchant can be used as an alliance link to enter the above alliance chain.
在示出的一种实施方式中，各个商家节点设备可以搭载用于生成私钥以及公钥的密钥算法，该商家节点设备在作为成员设备接入联盟链时，首先可以通过搭载的私钥以及公钥的生成硬件，或者调用搭载的密钥算法，创建一对私钥和公钥。或者，在实际应用中，各个商家所持有的私钥以及公钥，也可以由联盟链的运营方进行统一分配和下发。In one embodiment shown, each merchant node device can be equipped with a key algorithm for generating private keys and public keys. When the merchant node device accesses the alliance chain as a member device, it can first use the carried private key And the generation hardware of the public key, or call the carried key algorithm to create a pair of private key and public key. Or, in practical applications, the private key and public key held by each merchant can also be uniformly distributed and issued by the operator of the alliance chain.
然后，各个商家节点设备可以进一步构建一个用于发起注册的交易(transfer)，并基于生成的私钥对该交易进行签名后，将该交易在联盟链中进行发布，来申请加入联盟链。而联盟链中部分指定的成员节点设备在收到该交易后，可以基于对该交易进行签名时所使用的私钥对应的公钥，对该交易的签名进行验证，并在签名验证通过后，可以对该交易进行共识处理，并在共识通过后，允许该商家节点设备加入联盟链，然后可以对该商家节点设备的公钥进行计算，为该商家节点设备在联盟链中创建一个账户地址。此时，该商家节点设备作为成员节点设备成功加入联盟链，为该商家节点设备生成的账户地址，为该商家节点设备在联盟链上的身份。Then, each merchant node device can further construct a transaction (transfer) for initiating registration, and after signing the transaction based on the generated private key, publish the transaction in the alliance chain to apply for joining the alliance chain. After receiving the transaction, some designated member node devices in the alliance chain can verify the signature of the transaction based on the public key corresponding to the private key used to sign the transaction, and after the signature verification is passed, The transaction can be processed by consensus, and after the consensus is passed, the merchant node device is allowed to join the alliance chain, and then the public key of the merchant node device can be calculated to create an account address for the merchant node device in the alliance chain. At this time, the merchant node device successfully joins the alliance chain as a member node device, and the account address generated for the merchant node device is the identity of the merchant node device on the alliance chain.
当上述由若干商家节点设备构成的联盟链搭建完毕后，上述联盟链的运营方，依托于该联盟链来部署信用闭环业务。而加入该联盟链的商家，可以通过商家节点设备，通过向联盟链的分布式数据库中广播发布用户信用记录，来实现将用户信用记录在不同的商家中进行共享。After the above-mentioned consortium chain consisting of several merchant node devices is built, the operator of the above-mentioned consortium chain will rely on the consortium chain to deploy credit closed-loop business. Merchants joining the alliance chain can share user credit records among different merchants by broadcasting and publishing user credit records to the distributed database of the alliance chain through the merchant node equipment.
请参见图3，图3为本说明书示出的一种商户基于联盟链共享用户信用记录的流程图。Please refer to FIG. 3 , which is a flowchart of a merchant sharing user credit records based on an alliance chain shown in this specification.
如图3所示，商家节点设备可以获取待发布的用户信用记录，然后可以基于获取到的用户信用记录向联盟链发起记账。As shown in Figure 3, the merchant node device can obtain the user credit record to be released, and then initiate accounting to the alliance chain based on the obtained user credit record.
其中，待发布的用户信用记录，具体可以由商家通过商家节点设备手工录入，也可以由上述上述商家节点设备基于面向用户提供与信用相关的服务时，所产生的服务数据来自动生成。也即，商家节点设备可以获取商家手工录入的用户信用记录，作为待发布的用户信用记录；也可以来获取基于用户所产生的服务数据自动生成的用户数据记录，来作为待发布的用户信用记录。Wherein, the user credit record to be released may be manually entered by the merchant through the merchant node device, or may be automatically generated by the above-mentioned merchant node device based on the service data generated when providing credit-related services to users. That is to say, the merchant node device can obtain the user credit record manually entered by the merchant as the user credit record to be released; it can also obtain the user data record automatically generated based on the service data generated by the user as the user credit record to be released .
需要说明的是，上述用户信用记录的具体格式，在本说明书中不进行特别限定，在实际应用中，可以由上述联盟链的运营方，基于实际的需求，来为联盟链定制一套标准的数据格式。It should be noted that the specific format of the above-mentioned user credit records is not particularly limited in this manual. In practical applications, the operator of the above-mentioned alliance chain can customize a set of standard formats for the alliance chain based on actual needs. Data Format.
例如，在示出的一种实施方式中，上述用户信用记录具体可以是由以下字段构成的数据记录：For example, in one embodiment shown, the above-mentioned user credit record may specifically be a data record composed of the following fields:
时间戳字段，用于填充用户信用记录的录入或者产生的时间戳。该时间戳具体可以向部署的时间戳服务器进行查询得到。The timestamp field is used to fill in the entry or generated timestamp of the user's credit record. Specifically, the timestamp can be obtained by querying the deployed timestamp server.
类型字段，用于填充用户信用记录的类型标识。联盟链的运营方可以基于实际的需求，定义多种用户信用记录的类型；例如，在一个例子中，联盟链的运营方可以定义“服务使用记录”、“服务违约记录”以及“服务履约记录”三种类型的用户信用记录，并为以上三种记录分别定义一个对应的类型标识。The type field is used to fill in the type identifier of the user's credit record. The operator of the alliance chain can define various types of user credit records based on actual needs; for example, in one example, the operator of the alliance chain can define "service usage records", "service breach records" and "service performance records" "Three types of user credit records, and define a corresponding type identifier for each of the above three types of records.
记录内容字段，用于填充用户信息记录的具体内容。The record content field is used to fill in the specific content of the user information record.
用户身份字段，用于填充用户信用记录对应的用户身份；比如，身份证号、社会保障码等。The user identity field is used to fill in the user identity corresponding to the user credit record; for example, ID number, social security code, etc.
证明材料字段，用于填充用于证明该用户信用记录的有效性的证明材料；例如，以上述用户信用记录为“服务履约记录”为例，上述证明材料具体可以是能够证明该用户已经完成履约的用户数据；比如，以上述“服务履约记录”为“共享产品的履约服务记录”为例，上述证明材料具体可以是用户按期规划共享产品的订单数据、押金支付记录，等等。The proof material field is used to fill in the proof materials used to prove the validity of the user's credit record; For example, taking the above-mentioned "service performance record" as "shared product performance service record" as an example, the above-mentioned proof materials can specifically be the user's scheduled shared product order data, deposit payment records, and so on.
请继续参见图3，商家节点设备在基于获取到的用户信用记录向联盟链发起记账时，具体可以将上述用户信用记录，在联盟链中进行广播发布。Please continue to refer to Figure 3. When the merchant node device initiates accounting to the alliance chain based on the obtained user credit records, it can specifically broadcast and publish the above user credit records in the alliance chain.
在示出的一种实施方式中，上述商家节点设备可以将待发布的用户信用记录作为交易内容，构建一笔交易，然后基于持有的私钥对该交易进行签名。In one embodiment shown, the above-mentioned merchant node device may use the user credit record to be released as the transaction content, construct a transaction, and then sign the transaction based on the held private key.
请继续参见图3，当联盟链中的其它各节点设备接收到该笔交易后，可以对该笔交易进行验证，并在验证通过后将验证结果在联盟链中进行广播发布；Please continue to refer to Figure 3, when other node devices in the consortium chain receive the transaction, they can verify the transaction, and broadcast the verification result in the consortium chain after the verification is passed;
在本说明书中，对上述交易进行验证，具体可以包括对该交易的发布者的身份验证，以及交易内容的验证；其中，对上述交易内容的验证，又进一步可以包括对上述交易内容的完整性验证，以及对上述交易内容的有效性验证，In this specification, the verification of the above transaction may specifically include the verification of the identity of the publisher of the transaction and the verification of the transaction content; wherein, the verification of the above transaction content may further include the integrity of the above transaction content Verification, and verification of the validity of the above transaction content,
在实现时，商家节点设备在对上述交易进行签名时，通常可以对该交易进行计算得到内容摘要(比如hash值)，然后基于持有的私钥对该内容摘要进行加密得到数字签名。而其它各节点设备在接收到签名后的交易后，可以基于该商家节点设备的公开公钥对上述数字签名进行解密；如果成功解密，则表示发布该交易的商家节点设备的身份验证通过，该笔交易为由该商家节点设备发布的合法交易。During implementation, when the merchant node device signs the above transaction, it can usually calculate the transaction to obtain a content summary (such as a hash value), and then encrypt the content summary based on the held private key to obtain a digital signature. After receiving the signed transaction, other node devices can decrypt the above digital signature based on the public key of the merchant node device; if the decryption is successful, it means that the identity verification of the merchant node device that issued the transaction has passed, and The transaction is a legal transaction issued by the merchant node device.
其次，其它各节点设备还可以进一步对该交易重新进行计算得到一个内容摘要，然后将重新计算出的内容摘要，与通过解密数字签名得到的原始内容摘要进行匹配；如果二者匹配，表示对交易内容的完整性验证通过，该交易的交易内容在交易传输过程中未被非法篡改。Secondly, other node devices can further recalculate the transaction to obtain a content digest, and then match the recalculated content digest with the original content digest obtained by decrypting the digital signature; if the two match, it means that the transaction The integrity of the content has been verified, and the transaction content of the transaction has not been illegally tampered with during the transaction transmission.
进一步的，当该商家节点设备完成对该交易的发布者的身份验证，以及交易内容的完整性验证后，还可以基于作为交易内容的用户信用记录中记载的信息，来对该用户信用记录进行有效性验证。例如，商家节点设备可以读取用户信用记录中的“证明材料字段”中填充的证明材料，来验证用户信用记录的有效性。Further, after the merchant node device completes the identity verification of the issuer of the transaction and the integrity verification of the transaction content, it can also conduct the user credit record based on the information recorded in the user credit record as the transaction content. Validity verification. For example, the merchant node device can read the proof material filled in the "proof material field" in the user's credit record to verify the validity of the user's credit record.
请继续参见图3，当其它各节点设备对上述商家节点设备发布的交易验证通过后，可以将验证结果在联盟链中进行广播发布；其中，其它各节点设备也可以基于持有的私钥对验证结果进行签名，并且接收到该验证结果的节点设备，也可以基于与该私钥对应的公钥对该验证结果的数据签名进行验证，具体的实施细节本说明书中不再进行赘述。Please continue to refer to Figure 3. After other node devices pass the transaction verification issued by the merchant node device above, the verification result can be broadcast and released in the alliance chain; among them, other node devices can also be based on the private key they hold. The verification result is signed, and the node device receiving the verification result can also verify the data signature of the verification result based on the public key corresponding to the private key, and the specific implementation details will not be repeated in this specification.
相应的，其它各节点设备在获取到待分布的用户信用记录后，也可以通过相同的方式来构建交易，在联盟链上进行广播发布；而如果上述商家节点设备收到其它各节点设备发布的交易后，也可以采用相同的方式对该交易进行验证，然后向联盟链广播验证结果，在本说明书中不再进行赘述。Correspondingly, after other node devices obtain the user credit records to be distributed, they can also construct transactions in the same way and broadcast and publish them on the alliance chain; and if the above-mentioned merchant node devices receive After the transaction, the same method can also be used to verify the transaction, and then broadcast the verification result to the alliance chain, which will not be repeated in this manual.
在本说明书中，上述商家节点设备，可以收集当前记账周期内由区块链中的各节点设备(包括该商家节点设备)广播发布至联盟链，且由联盟链中的各节点设备共同验证通过的用户信用记录。In this specification, the above-mentioned merchant node device can collect and broadcast to the alliance chain by each node device (including the merchant node device) in the blockchain in the current billing cycle, and be jointly verified by each node device in the alliance chain. Passed user credit history.
其中，上述共同验证通过，具体是指经过联盟链中大多数的节点设备验证通过。即在联盟链中，只要上述用户信用记录由联盟链中的大多数节点设备验证通过，得到了联盟链中大多数节点设备的共识认可后，即认为该用户信用记录由联盟链中的各节点设备共同验证通过。Among them, passing the above common verification specifically refers to passing the verification of most of the node devices in the alliance chain. That is, in the consortium chain, as long as the above-mentioned user credit record is verified by most of the node devices in the consortium chain, and the consensus approval of the majority of node devices in the consortium chain is obtained, it is considered that the user credit record is verified by each node in the consortium chain. Device co-authentication passed.
在示出的一种实施方式中，上述商家节点设备在收集当前记账周期内由区块链中的各节点设备广播发布至联盟链，且由联盟链中的各节点设备共同验证通过的用户信用记录时，具体可以收集当前记账周期内，由联盟链中的各节点设备(包括该商家节点设备)广播发布至联盟链的用户信用记录；以及，收集联盟链中的各节点设备对当前记账周期内广播发布至区块链的用户信用记录的验证结果；然后基于收集到的信息，来筛选出当前记账周期内由区块链中的各节点设备广播发布至区块链的用户信用记录中，由各节点设备中预设比例的节点设备验证通过的用户信用记录。In one embodiment shown, the above-mentioned merchant node device is broadcast and published to the consortium chain by each node device in the blockchain within the collection of the current billing cycle, and each node device in the consortium chain jointly verifies the user In the case of credit records, it is possible to collect the user credit records broadcast and published to the alliance chain by each node device (including the merchant node device) in the alliance chain during the current accounting cycle; Broadcast the verification results of user credit records published to the blockchain during the billing cycle; then, based on the collected information, screen out users who are broadcast and published to the blockchain by each node device in the blockchain during the current billing cycle In the credit record, the user credit record is verified by a preset proportion of node devices in each node device.
其中，上述预设比例的取值大小，在本说明书中不进行特别限定，具体可以是一个大于50％的任意比值；比如，51％，或者100％。Wherein, the value of the above-mentioned preset ratio is not particularly limited in this specification, and may specifically be any ratio greater than 50%; for example, 51%, or 100%.
在本说明书中，当上述商家节点设备收集到当前记账周期内由区块链中的各节点设备广播发布至联盟链，且由联盟链中的各节点设备共同验证通过的用户信用记录后，可以基于收集到的这些用户信用记录来构建一个候选区块，然后基于联盟链所支持的共识算法，在联盟链中发起对该候选区块中所收录的用户信用记录进行共识处理，来“竞争”记账权限。In this specification, when the above-mentioned merchant node equipment collects the user credit records that are broadcast and released to the alliance chain by each node equipment in the blockchain in the current billing cycle, and are jointly verified by each node equipment in the alliance chain, A candidate block can be constructed based on the collected user credit records, and then based on the consensus algorithm supported by the alliance chain, consensus processing on the user credit records included in the candidate block is initiated in the alliance chain to "compete "Accounting authority.
其中，上述联盟链中所支持的共识算法的具体类型，在本说明书中不进行限定限定，在实际应用中，可以采用一些适宜在联盟链中使用的经典共识算法(比如PBFT算法)，也可以由联盟链的运营方基于实际的业务需求，来定制一些能够高效处理交易的共识算法。Among them, the specific types of consensus algorithms supported in the above alliance chains are not limited in this specification. In practical applications, some classic consensus algorithms (such as PBFT algorithms) suitable for use in alliance chains can be used, or Based on actual business needs, the operator of the consortium chain customizes some consensus algorithms that can efficiently process transactions.
在示出的一种实施方式中，上述联盟链中支持的共识算法，具体可以是由上述联盟链的运营方定制的，基于各商家节点设备在当前记账周期内发布的用户信用记录的数据量，将在当前记账周期内发布的用户信用记录的数量最多的发布方节点设备选举为记账节点，对候选区块进行共识处理的共识算法。In one embodiment shown, the consensus algorithm supported in the above-mentioned consortium chain can be specifically customized by the operator of the above-mentioned consortium chain, based on the data of user credit records released by each merchant node device in the current billing cycle A consensus algorithm that elects the issuer node device with the largest number of user credit records issued in the current accounting cycle as the accounting node, and performs consensus processing on the candidate blocks.
在实现时，上述商家节点设备在发起对上述候选区块进行共识处理时，首先可以确定收集到的用户信用记录对应的发布方节点设备；比如，可以在承载用户信用记录的交易中添加发布方节点设备的设备标识；然后可以统计各发布方节点设备在当前记账周期内所发布的用户信用记录的数量；最后，可以将在当前记账周期内所发布的用户信用记录的数量最多的发布方节点设备，确定为记账节点设备。During implementation, when the above-mentioned merchant node device initiates consensus processing on the above-mentioned candidate blocks, it can first determine the issuer node device corresponding to the collected user credit records; The device identification of the node device; then the number of user credit records issued by each issuer node device in the current billing cycle can be counted; finally, the number of user credit records issued in the current billing cycle can be released The party node device is determined as the billing node device.
其中，在实际应用中，联盟链中的节点设备所发布的用户信用记录中，可能存在一些已经在联盟链的分布式数据库中存储的重复记录，在这种情况下，通过上述共识算法所共识出的记账节点，可能会存在不准确的问题；比如，一些恶意的节点设备，可能会通过发布大量重复记录，来取得记账权限；而针对这种情况，按照上述共识算法，可能会将这类恶意的节点设备选举为记账节点。Among them, in practical applications, among the user credit records issued by node devices in the consortium chain, there may be some duplicate records that have been stored in the distributed database of the consortium chain. The out-of-the-box accounting nodes may have inaccurate problems; for example, some malicious node devices may obtain accounting authority by publishing a large number of duplicate records; and in this case, according to the above consensus algorithm, the Such malicious node devices are elected as accounting nodes.
基于此，在示出的一种实施方式中，在上述共识算法中，可以将各发布方节点设备在当前记账周期内所发布的用户信用记录的数量，声明为各发布方节点设备在当前记账周期内发布的，且在联盟链的分布式数据库中不存在对应的重复记录的用户信用记录的数量。Based on this, in one embodiment shown, in the above consensus algorithm, the number of user credit records issued by each issuer node device in the current billing period can be declared as the number of user credit records issued by each issuer node device in the current accounting period The number of user credit records issued during the billing cycle and that do not have corresponding duplicate records in the distributed database of the alliance chain.
在这种情况下，上述商家节点设备在统计各发布方节点设备在当前记账周期内所发布的用户信用记录的数量时，可以向联盟链的分布式数据库发起查询，来确定各发布方节点设备所发布的用户信用记录，是否已经在联盟链的分布式数据库中存在重复记录；In this case, when the above-mentioned merchant node device counts the number of user credit records issued by each issuer node device in the current billing cycle, it can initiate a query to the distributed database of the alliance chain to determine the number of each issuer node. Whether the user credit record issued by the device has duplicate records in the distributed database of the alliance chain;
例如，在实现时，可以通过计算待查询的用户信用记录的hash值，基于该hash值定位包含该用户信用记录的区块，然后通过在定位出的该区块的Merkle树中，遍历该用户信用记录的hash值，来确定该用户信用记录是否已经收录在区块链的区块中。For example, during implementation, the hash value of the user's credit record to be queried can be calculated, and the block containing the user's credit record can be located based on the hash value, and then the user can be traversed in the Merkle tree of the located block. The hash value of the credit record is used to determine whether the user's credit record has been included in the block of the blockchain.
进一步的，上述商家节点设备可以将这些在联盟链中存在重复记录的用户信用记录从上述候选区块中移除，然后统计各发布方节点设备在当前记账周期内发布的，且在联盟链的分布式数据库中不存在对应的重复记录的用户信用记录的数量，然后基于上述共识算法，将在当前记账周期内发布的用户信用记录的数量最多的发布方节点设备，确定为记账节点设备。Further, the above-mentioned merchant node device can remove these user credit records that have duplicate records in the alliance chain from the above-mentioned candidate blocks, and then count the information issued by each issuer node device in the current billing cycle, and in the alliance chain The number of user credit records that do not have corresponding duplicate records in the distributed database, and then based on the above consensus algorithm, the issuer node device with the largest number of user credit records issued in the current accounting cycle is determined as the accounting node equipment.
通过这种方式，可以避免一些恶意的节点设备，可通过发布大量重复记录，来取得记账权限的问题。In this way, some malicious node devices can avoid the problem of obtaining accounting authority by publishing a large number of duplicate records.
当然，上述共识算法中的算法逻辑，除了可以是以上描述的，将在当前记账周期内发布的用户信用记录的数量最多的发布方节点设备选举为记账节点，以外，在实际应用中，也可以是由联盟链的运营方定制的其它形式的算法逻辑；例如，将在当前记账周期内发布的用户信用记录的质量最高、发布速度最快的商家节点设备选举为记账节点；或者，也可以由联盟链的运营方基于一定的规则(比如按照一定的顺序)将各个节点设备中的特定节点指定为为记账节点，在本说明书中不再进行一一列举。Of course, the algorithm logic in the above-mentioned consensus algorithm, in addition to the above-described election of the issuer node device with the largest number of user credit records issued in the current accounting cycle, as the accounting node, in practical applications, It can also be other forms of algorithmic logic customized by the operator of the consortium chain; for example, the merchant node device with the highest quality and fastest publishing speed of the user's credit records issued in the current accounting cycle is elected as the accounting node; or , the operator of the consortium chain can also designate a specific node in each node device as an accounting node based on certain rules (such as in a certain order), and will not be listed one by one in this specification.
请继续参见图3，如果上述商家节点设备最终被确定为记账节点，此时该商家节点设备生成的候选区块共识通过，该商家节点设备可以将该候选区块作为最新的区块，在联盟链中进行广播发布。而接收到该最新的区块的各个节点设备，可以分别基于该最新的区块来发起记账，将该最新的区块与历史区块进行链接，进而加入到联盟链的分布式数据中进行永久存储。Please continue to refer to Figure 3. If the above-mentioned merchant node device is finally determined to be an accounting node, the candidate block generated by the merchant node device has passed the consensus, and the merchant node device can use the candidate block as the latest block. Broadcast and publish in the alliance chain. And each node device that receives the latest block can initiate bookkeeping based on the latest block, link the latest block with the historical block, and then add it to the distributed data of the alliance chain. permanent storage.
在本说明书中，由于作为联盟成员的商家，可能分别对应不同的商家类型；例如，加入联盟链的各个商家所提供的服务，可能隶属于不同的行业；而在信用闭环业务中，不同的商家的信用评价体系，可能会存在一定的差异；因此，在一种实施方式中，联盟链的运营方，可以基于作为联盟成员的商家的具体类型，将该联盟链划分为一主链，以及与主链锚定的若干分别对应不同的商家类型的子链。In this manual, because merchants who are members of the alliance may correspond to different types of merchants; for example, the services provided by each merchant joining the alliance chain may belong to different industries; and in the credit closed-loop business, different merchants There may be some differences in the credit evaluation system; therefore, in one implementation, the operator of the alliance chain can divide the alliance chain into a main chain based on the specific types of merchants that are members of the alliance. Several sub-chains anchored by the main chain correspond to different merchant types.
例如，以加入联盟的链的商家包含连锁酒店、超市、以及共享产品服务提供商为等商家为例，可以将连锁酒店、超市、以及共享产品服务提供商等商家的节点设备，划分至不同的子链中，与主链进行锚定。For example, taking the chain of merchants joining the alliance includes chain hotels, supermarkets, and shared product service providers as an example, the node devices of chain hotels, supermarkets, and shared product service providers can be divided into different In the sub-chain, it is anchored with the main chain.
其中，联盟链中的主链以及子链的运行方式可以完全相同，子链中的发布的用户信用记录，可以通过以上示出的相同的方式，汇总后以区块的形式加入到主链中。Among them, the operation mode of the main chain and the sub-chain in the consortium chain can be exactly the same, and the published user credit records in the sub-chain can be added to the main chain in the form of blocks in the same way as shown above. .
一方面，对于子链中的商家节点设备而言，在收集到当前记账周期内由子链中的各节点设备广播发布至上述子链，且由上述子链中的各节点设备共同验证通过的用户信用记录后，可以基于收集到的用户信用记录创建候选区块，并在被确定为记账节点后，除了可以将该候选区块作为最新的区块广播发布至该子链，加入到该子链的分布式数据库以外，也可以将该候选区块广播发布至主链，加入到主链中。On the one hand, for the merchant node devices in the sub-chain, within the current billing period collected, each node device in the sub-chain broadcasts and publishes to the above-mentioned sub-chain, and is jointly verified by each node device in the above-mentioned sub-chain After the user credit record, a candidate block can be created based on the collected user credit record, and after being determined as a bookkeeping node, in addition to broadcasting the candidate block as the latest block to the sub-chain, it can be added to the In addition to the distributed database of the sub-chain, the candidate block can also be broadcast to the main chain and added to the main chain.
另一方面，对于主链中的商家节点设备而言，在收集到当前记账周期内由主链以及各子链中的各节点设备广播发布至上述主链，且由上述主链中的各节点设备共同验证通过的用户信用记录后(即由主链中的节点设备来验证子链中发布的用户信用记录)，可以基于收集到的用户信用记录创建候选区块，并在被确定为记账节点后，将该候选区块广播发布至主链，加入到主链中。On the other hand, for the merchant node equipment in the main chain, the main chain and each node equipment in each sub-chain broadcast to the above-mentioned main chain within the collection of the current billing period, and each of the above-mentioned main chain After the node device jointly verifies the passed user credit record (that is, the node device in the main chain verifies the user credit record issued in the sub-chain), a candidate block can be created based on the collected user credit record, and when it is determined as a record After the account node, broadcast the candidate block to the main chain and add it to the main chain.
当由商家节点设备发布的用户信用记录，被成功收录存储至联盟链的分布式数据库中，各个商家节点设备可以通过查询联盟链中的用户信用记录，与共享由其它商家节点设备发布的用户信用记录，并使用联盟链中收录存储的用户信用记录，来完成信用闭环业务的线上或者线下运营；When the user credit record issued by the merchant node device is successfully included and stored in the distributed database of the alliance chain, each merchant node device can share the user credit records issued by other merchant node devices by querying the user credit record in the alliance chain. Records, and use the user credit records recorded and stored in the alliance chain to complete the online or offline operation of the credit closed-loop business;
例如，多个商家节点设备，可以基于联盟链中收录存储的用户信用记录，对用户进行联合催缴、联合惩戒、以及联合激励等，来联合监督和促进用户积极履约，实现同行业，以及跨行业间的业务联动。比如，多个商家在获取到联盟链中最新收录的用户信用记录后，均可以基于各自触达用户的渠道，对用户进行催缴、惩戒、激励等。For example, multiple merchant node devices can jointly supervise and promote users to actively perform contracts based on the user credit records recorded and stored in the alliance chain, to jointly supervise and promote users to actively perform contracts, and realize the same industry and cross-border cooperation. Inter-industry business linkage. For example, after multiple merchants obtain the latest user credit records included in the alliance chain, they can urge, punish, and motivate users based on their respective channels to reach users.
在本说明书中，上述联盟链具体也可以引入记账奖励机制。所谓记账奖励机制，具体是指参与记账的节点设备，可以获得由联盟链分配的一笔奖励。In this specification, the above-mentioned consortium chain can also specifically introduce a bookkeeping reward mechanism. The so-called bookkeeping reward mechanism specifically refers to the node equipment participating in bookkeeping, which can obtain a reward allocated by the alliance chain.
其中，参与记账的节点设备，具体可以包括取得记账权限的节点设备，也可以包括所有成功在联盟链收录了用户信用记录的节点设备。Among them, the node devices that participate in bookkeeping can specifically include node devices that have obtained bookkeeping authority, and can also include all node devices that have successfully included user credit records in the alliance chain.
在示出的一种实施方式中，如果联盟链中的商家节点设备被确定为记账节点，可以获取到联盟链生成的预设数量的虚拟资源，然后将获取到的虚拟资源下发至与该商家节点设备对应的账户地址进行持有。In one embodiment shown, if the merchant node device in the consortium chain is determined to be an accounting node, it can obtain a preset number of virtual resources generated by the consortium chain, and then send the obtained virtual resources to the The account address corresponding to the merchant node device is held.
在示出的另一种实施方式中，如果联盟链中的商家节点设备所发布的用户信用记录最终被成功收录存储至联盟链的分布式数据库(即该节点设备并不是记账节点，其发布的用户信用记录被记账节点成功收录至联盟链)，可以获取到联盟链生成的预设数量的虚拟资源，然后将获取到的虚拟资源下发至与该商家节点设备对应的账户地址进行持有。In another embodiment shown, if the user credit record issued by the merchant node device in the consortium chain is finally successfully included and stored in the distributed database of the consortium chain (that is, the node device is not an accounting node, it issues The credit record of the user is successfully included in the alliance chain by the accounting node), and the preset number of virtual resources generated by the alliance chain can be obtained, and then the obtained virtual resources are sent to the account address corresponding to the merchant node device for maintenance Have.
其中，联盟链在生成虚拟资源时，具体可以由参与记账的商家节点设备基于运行的算法自动生成，也可以由联盟链中指定的节点设备来生成，然后进行统一下发；例如，可以在联盟链中的节点设备中指定一权威节点设备或者中心节点设备，由该节点设备负责面向参与记账的各个商家节点设备生成并下发虚拟资源作为记账奖励。Among them, when the alliance chain generates virtual resources, it can be automatically generated by the merchant node equipment participating in the bookkeeping based on the running algorithm, or it can be generated by the node equipment specified in the alliance chain, and then issued uniformly; for example, it can be in The node devices in the alliance chain designate an authoritative node device or a central node device, which is responsible for generating and issuing virtual resources to each merchant node device participating in the bookkeeping as a bookkeeping reward.
上述虚拟资源的具体类型，在本说明书中不进行特别限定；例如，在实际应用中，上述虚拟资源具体可以是积分，或者与积分类似的其它形式的虚拟奖励。The specific types of the above-mentioned virtual resources are not particularly limited in this specification; for example, in practical applications, the above-mentioned virtual resources may specifically be points, or other forms of virtual rewards similar to points.
在本说明书中，上述虚拟资源具体用于取得联盟链的分布式数据库中收录存储的用户信用记录的使用权限。对于联盟链中的节点设备而言，如果需要使用已经收录存储在联盟链的分布式数据库中的用户信用记录，则需要“消耗”一定数量的虚拟资源。In this specification, the above-mentioned virtual resources are specifically used to obtain the right to use the user credit records recorded and stored in the distributed database of the consortium chain. For node devices in the consortium chain, if they need to use user credit records that have been included and stored in the distributed database of the consortium chain, they need to "consume" a certain amount of virtual resources.
在实现时，联盟链的运营方，可以在联盟链中定义使用联盟链中的用户信用记录时，所要“消耗”的虚拟资源的数量。When implementing, the operator of the consortium chain can define in the consortium chain the amount of virtual resources to be "consumed" when using the user credit records in the consortium chain.
在示出的一种实施方式中，以上述虚拟资源为积分为例，联盟链的运营方可以预先在联盟链中发布一个与用户信用记录查询相关的智能合约，并在该智能合约中声明查询和使用该联盟链中的用户信用记录时，所要“消耗”的虚拟资源的数量。同时，还可以在智能合约中声明与用户信用记录使用相关的虚拟资源“扣除”逻辑；比如，该逻辑可以是收到针对分布式数据库中的用户信用记录的数据查询请求后，可以基于需要查询的用户信用记录的数量，从查询方的账户地址中“扣除”一定数量的虚拟资源。In one embodiment shown, taking the above-mentioned virtual resources as points as an example, the operator of the consortium chain can pre-publish a smart contract related to user credit record query in the consortium chain, and declare the query in the smart contract And the amount of virtual resources to be "consumed" when using the user credit records in the consortium chain. At the same time, the virtual resource "deduction" logic related to the use of user credit records can also be declared in the smart contract; for example, the logic can be based on the need to query According to the number of user credit records, a certain amount of virtual resources will be "deducted" from the account address of the inquiring party.
当商家需要使用联盟链中收录存储的用户信用记录，可以通过商家节点设备向联盟链的分布式数据库发起一个数据查询请求(交易)，商家节点设备在收到该数据查询请求后，可以响应该数据查询请求，调用上述智能合约，基于上述智能合约中声明的使用联盟链中的用户信用记录时，所要“消耗”的积分数量，以及本次需要查询的用户信用记录的数量，来计算本次查询所要消耗的积分数量，然后从该商家节点设备对应的账户地址中扣除相应数量的积分。当然，如果商家节点设备对应的账户地址中积分数量不足，此时该商家节点设备可以向用户发出查询失败的提示。When a merchant needs to use the user credit records recorded and stored in the alliance chain, it can initiate a data query request (transaction) to the distributed database of the alliance chain through the merchant node device. After receiving the data query request, the merchant node device can respond to the Data query request, calling the above smart contract, based on the number of points to be "consumed" when using the user credit records in the alliance chain declared in the above smart contract, and the number of user credit records that need to be queried this time, to calculate this time Query the number of points to be consumed, and then deduct the corresponding number of points from the account address corresponding to the merchant node device. Of course, if the number of credits in the account address corresponding to the merchant node device is insufficient, the merchant node device may send a prompt to the user that the query fails.
通过这种方式，由于只有参与记账的商家节点设备，能够获取到联盟链的记账奖励，因此不仅可以鼓励各个商家将运营线上或者线下业务所产生的用户信用记录通过发布至联盟链共享给其它商家，还可以将联盟链中收录存储的用户信用记录的使用权限，向参与记账的商家倾斜；同时，还可以提高联盟链中的数据查询和使用的门槛，可以限制一些不参与记账的商家，或者接入联盟链的非商家用户，来获取和使用各个商家共享的用户信用记录。In this way, since only the merchant node equipment participating in bookkeeping can obtain the bookkeeping rewards of the alliance chain, it can not only encourage each merchant to publish the user credit records generated by operating online or offline business to the alliance chain Sharing with other merchants can also tilt the use authority of user credit records recorded and stored in the alliance chain to merchants participating in bookkeeping; at the same time, it can also increase the threshold for data query and use in the alliance chain, and can limit some non-participating Accounting merchants, or non-merchant users who access the alliance chain, obtain and use user credit records shared by various merchants.
通过以上实施例可见，一方面，由于区块链具有历史可追溯性和不可篡改性，因此通过这种方式能够在区块链上真实的记录一段时间内产生的用户信用记录，并且所有用户信用记录均可以在区块链上进行追溯；而且，由于用户信用记录是由所有节点设备共同验证和维护，要进行用户信用记录的篡改，则需要控制大多数的节点设备才能做到，因此可以确保用户信用记录的公正性；It can be seen from the above embodiments that, on the one hand, since the blockchain has historical traceability and non-tamperability, in this way, the user credit records generated within a period of time can be recorded on the blockchain, and all user credit All records can be traced on the blockchain; moreover, since user credit records are jointly verified and maintained by all node devices, to tamper with user credit records, it is necessary to control most of the node devices, so it can be ensured The impartiality of user credit records;
另一方面，由于区块链中的各个节点设备产生的用户信用记录是共享的，各个节点设备通过在链上进行查询，就可以获得其它节点设备发布的用户信用记录，因此使得信用闭环可以不集中在其中一个节点设备，各个节点设备之间可以互相共享和监督；而且，在部署信用闭环业务时，触达用户的渠道也相应增多，多个节点设备可以通过使用链上的用户信用记录，对用户进行联合催缴、联合惩戒、以及联合激励等，来联合监督和促进用户积极履约。On the other hand, since the user credit records generated by each node device in the blockchain are shared, each node device can obtain the user credit records issued by other node devices by querying on the chain, so that the credit closed loop can not Concentrated on one of the node devices, each node device can share and supervise each other; moreover, when deploying the credit closed-loop business, the channels to reach users will increase accordingly, and multiple node devices can use the user credit records on the chain, Joint reminders, joint punishments, and joint incentives are carried out on users to jointly supervise and promote users' active performance of contracts.
