具体实施方式Detailed ways
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本说明书一个或多个实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本说明书一个或多个实施例的一些方面相一致的装置和方法的例子。Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. Implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of this specification. Rather, they are merely examples of apparatuses and methods consistent with aspects of one or more embodiments of the present specification as recited in the appended claims.
需要说明的是：在其他实施例中并不一定按照本说明书示出和描述的顺序来执行相应方法的步骤。在一些其他实施例中，其方法所包括的步骤可以比本说明书所描述的更多或更少。此外，本说明书中所描述的单个步骤，在其他实施例中可能被分解为多个步骤进行描述；而本说明书中所描述的多个步骤，在其他实施例中也可能被合并为单个步骤进行描述。It should be noted that in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or less steps than those described in this specification. In addition, a single step described in this specification may be decomposed into multiple steps for description in other embodiments; multiple steps described in this specification may also be combined into a single step in other embodiments describe.
在现有基于平台的保险投保业务场景中，保险平台运营方通常需与保险公司线下签署保单代理合约(或保险产品代理合约)，以为保险平台上提供用户进行投保的保单提供代理权限及保险内容的合理性支持。线下签署的保单代理合约，未形成结构化的数据，因此使用效率不高；而且核对或者查询线下的合约数据均需要工作人员手动进行，且分散签署的合约数据较难集中，难以基于合约数据进行抽象或建模，对合约数据的使用不方便。In the existing platform-based insurance application business scenario, the insurance platform operator usually needs to sign a policy agency contract (or insurance product agency contract) with the insurance company offline to provide agency authority and insurance coverage for the insurance policies provided by users on the insurance platform. Reasonable support for the content. The insurance policy agency contract signed offline does not form structured data, so the use efficiency is not high; moreover, checking or querying offline contract data requires manual work by staff, and it is difficult to centralize contract data signed separately, and it is difficult to The data is abstracted or modeled, and the use of contract data is inconvenient.
有鉴于此，在本说明书示出的一种实施方式中，提供了一种基于区块链的数据处理方法，应用于包括业务平台方节点设备、用户客户端和业务提供方客户端的区块链网络，所述用户客户端和所述业务提供方客户端与所述业务平台节点设备通信连接；所述区块链的分布式数据库内存储有所述业务平台方与所述业务提供方签署的业务代理合约，所述业务代理合约对应有唯一性的识别码；所述业务平台节点设备配置有与所述业务代理合约对应的至少一份业务服务数据。In view of this, in one embodiment shown in this specification, a data processing method based on block chain is provided, which is applied to the block chain including service platform node device, user client and service provider client. network, the user client and the service provider client communicate with the service platform node device; the distributed database of the block chain stores the information signed by the service platform and the service provider A business proxy contract, the business proxy contract corresponds to a unique identification code; the business platform node device is configured with at least one piece of business service data corresponding to the business proxy contract.
本说明书一个或多个实施例所述的区块链网络，具体可指一个各节点设备通过共识机制达成的、具有分布式数据存储结构的P2P网络系统，该区块链内的数据分布在时间上相连的一个个“区块(block)”之内，后一区块包含前一区块的数据摘要，且根据具体的共识机制(如POW、POS、DPOS或PBFT等)的不同，达成全部或部分节点的数据全备份。本领域的技术人员熟知，由于区块链网络系统在相应共识机制下运行，已收录至区块链数据库内的数据很难被任意的节点篡改，例如采用Pow共识的区块链，至少需要全网51％算力的攻击才有可能篡改已有数据，因此区块链系统有着其他中心化数据库系统所无法比拟的保证数据安全、防攻击篡改的特性。由此可知，被收录至区块链的分布式数据库中的数据不会被攻击或篡改，从而保证了存证入区块链的分布式数据库的数据信息的真实可靠性。The blockchain network described in one or more embodiments of this specification can specifically refer to a P2P network system with a distributed data storage structure achieved by each node device through a consensus mechanism. The data in the blockchain is distributed in time In the "blocks" connected above, the latter block contains the data summary of the previous block, and according to the specific consensus mechanism (such as POW, POS, DPOS or PBFT, etc.), all Or full data backup of some nodes. Those skilled in the art are well aware that since the blockchain network system operates under the corresponding consensus mechanism, the data that has been included in the blockchain database is difficult to be tampered with by any node. Only an attack of 51% of the computing power of the network can tamper with existing data. Therefore, the blockchain system has the characteristics of ensuring data security and preventing attack and tampering that other centralized database systems cannot match. It can be seen from this that the data recorded in the distributed database of the blockchain will not be attacked or tampered with, thereby ensuring the authenticity and reliability of the data information stored in the distributed database of the blockchain.
区块链网络的示例类型可以包括公有区块链网络、私有区块链网络和联盟区块链网络。尽管术语区块链通常与比特币加密货币网络相关联，但是本文使用的区块链可指代不参考任何特定用例的DLS(分布式账本系统)。Example types of blockchain networks may include public blockchain networks, private blockchain networks, and consortium blockchain networks. Although the term blockchain is often associated with the Bitcoin cryptocurrency network, blockchain as used herein may refer to a DLS (Distributed Ledger System) without reference to any particular use case.
在公有区块链网络中，共识过程由共识网络的节点控制。例如，数百、数千、甚至数百万个实体可以在公有区块链网络中协作，每个实体在公有区块链网络中操作至少一个节点。因此，公有区块链网络可以被认为是相对于参与实体的公有网络。示例公有区块链网络包括比特币网络，比特币网络是对等支付网络。比特币网络利用分布式账本，被称为区块链。然而如上所述，术语区块链通常用于指代不特别参考比特币网络的分布式账本。In a public blockchain network, the consensus process is controlled by the nodes of the consensus network. For example, hundreds, thousands, or even millions of entities can collaborate in a public blockchain network, with each entity operating at least one node in the public blockchain network. Therefore, a public blockchain network can be thought of as a public network relative to participating entities. Example public blockchain networks include the Bitcoin network, which is a peer-to-peer payment network. The Bitcoin network utilizes a distributed ledger, known as the blockchain. As mentioned above, however, the term blockchain is often used to refer to a distributed ledger without specific reference to the Bitcoin network.
通常，公有区块链网络支持公有交易。公有交易与公有区块链网络内的所有节点共享，并存储在全局区块链中。全局区块链是跨所有节点复制的区块链。也就是说，对于全局区块链，所有节点处于完全一致的状态。为了达成共识(例如，同意向区块链添加块)，在公有区块链网络内实施共识协议。示例共识协议包括但不限于，在比特币网络中实施的工作量证明(proof-of-work，POW)。Typically, public blockchain networks support public transactions. Public transactions are shared with all nodes within the public blockchain network and stored in the global blockchain. A global blockchain is a blockchain replicated across all nodes. That is, for the global blockchain, all nodes are in a completely consistent state. In order to achieve consensus (e.g. agree to add blocks to the blockchain), a consensus protocol is implemented within the public blockchain network. Example consensus protocols include, but are not limited to, proof-of-work (POW) implemented in the Bitcoin network.
通常，私有区块链网络提供给特定实体，特定实体集中控制读取和写入权限。该实体控制哪些节点能够参与区块链网络。因此，私有区块链网络通常被称为许可网络，其对允许谁参与网络及其参与水平(例如，仅在某些交易中)施加限制。可以使用各种类型的访问控制机制(例如，现有参与者投票添加新实体，监管机构可以控制准入)。Typically, private blockchain networks are provided to specific entities that centrally control read and write permissions. This entity controls which nodes are able to participate in the blockchain network. For this reason, private blockchain networks are often referred to as permissioned networks, which impose restrictions on who is allowed to participate in the network and their level of participation (e.g., only in certain transactions). Various types of access control mechanisms can be used (e.g. existing participants vote to add new entities, regulators can control access).
通常，联盟区块链网络在参与实体中是私有的。在联盟区块链网络中，共识过程由授权的一组节点(联盟成员节点)控制，一个或多个节点由相应的实体(例如，企业)操作。例如，由十(10)个实体(例如，企业)组成的联盟可以操作联盟区块链网络，每个实体在该联盟区块链网络中操作至少一个节点。因此，就参与实体而言，联盟区块链网络可以被认为是私有网络。在一些示例中，每个实体(节点)必须对每个块进行签名，以使该块有效并将有效的块添加到区块链。在一些示例中，至少实体(节点)的子集(例如，至少7个实体)必须对每个块进行签名以使该块有效，并且将有效的块添加到区块链。Typically, consortium blockchain networks are private among participating entities. In a consortium blockchain network, the consensus process is controlled by an authorized group of nodes (confederation member nodes), and one or more nodes are operated by corresponding entities (eg, enterprises). For example, a consortium of ten (10) entities (eg, businesses) may operate a consortium blockchain network, each entity operating at least one node in the consortium blockchain network. As such, a consortium blockchain network can be considered a private network as far as participating entities are concerned. In some examples, each entity (node) must sign each block in order for the block to be valid and to add the valid block to the blockchain. In some examples, at least a subset of entities (nodes) (eg, at least 7 entities) must sign each block for the block to be valid, and valid blocks are added to the blockchain.
可以预期，本说明书所提供的实施方式能够在任何合适类型的区块链网络中实现。It can be expected that the implementations provided in this specification can be implemented in any suitable type of blockchain network.
本说明书一个或多个实施例所述的节点(或节点设备)是指可通过遵循相应节点协议、运行节点协议程序的安装来加入该区块链，作为该区块链的节点。本领域的技术人员通常将具有区块链分布式数据库的数据全备份的节点设备称为全节点，将具有区块链分布式数据库的部分备份数据(如仅有区块头的数据)的节点设备称为轻节点等。在本说明书的一个或多个实施例中，并不限定上述业务平台方节点设备的节点类型。本说明书也不限定上述业务平台节点设备的个数，业务平台方可以对应一个设备终端或服务器，也可以对应多个设备终端或服务器以作为上述区块链的节点设备。The node (or node device) described in one or more embodiments of this specification refers to a node that can join the blockchain by following the corresponding node protocol and running the installation of the node protocol program, as the node of the blockchain. Those skilled in the art usually refer to a node device with full data backup of the blockchain distributed database as a full node, and a node device with partial backup data of the blockchain distributed database (such as only the data of the block header) called light nodes etc. In one or more embodiments of this specification, the node type of the above-mentioned service platform node device is not limited.

For example, the terms and components of a smart contract can be represented as objects that are processed by the application implementing the smart contract. A smart contract (or an object within a smart contract) can call another smart contract (or an object within the same smart contract) just like any other object-oriented object. For example, a call made by an object may be a call to create, update, delete, propagate, or communicate with an object of another class. Calls between objects may be implemented by functions, methods, application programming interfaces (application programming interface, API) or other call mechanisms. For example, a first object may call a function to create a second object.
