Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with aspects of one or more embodiments of the present description as detailed in the accompanying claims.
It should be noted that: in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the method may include more or fewer steps than described in this specification. Furthermore, individual steps described in this specification, in other embodiments, may be described as being split into multiple steps; while various steps described in this specification may be combined into a single step in other embodiments.
In the existing platform-based insurance application service scenario, an insurance platform operator typically needs to sign an insurance policy agency contract (or an insurance product agency contract) offline with an insurance company to provide agency rights and reasonability support of insurance contents for providing insurance policies for users to apply on the insurance platform. The online signed policy agent contract does not form structured data, so that the use efficiency is low; moreover, checking or inquiring the contract data under the line is performed manually by a worker, and the contract data which is signed in a scattered way is difficult to concentrate, difficult to abstract or model based on the contract data, and inconvenient to use.
In view of this, in one embodiment shown in the present specification, there is provided a blockchain-based data processing method applied to a blockchain network including a service platform side node device, a user client, and a service provider client, the user client and the service provider client being communicatively connected to the service platform side node device; the distributed database of the blockchain stores service agent contracts signed by the service platform side and the service provider, and the service agent contracts correspond to unique identification codes; the business platform node device is configured with at least one business service data corresponding to the business agent contract.
The blockchain network in one or more embodiments of the present disclosure may specifically refer to a P2P network system with a distributed data storage structure, where each node device is implemented by a consensus mechanism, and data in the blockchain is distributed in blocks (blocks) that are temporally connected, where a later block includes a data summary of a previous block, and a full backup of data of all or part of nodes is implemented according to a specific consensus mechanism (such as POW, POS, DPOS or PBFT). Those skilled in the art are familiar with that, since the blockchain network system operates under the corresponding consensus mechanism, the data recorded in the blockchain database is difficult to be tampered by any node, for example, the blockchain adopting Pow consensus, and at least the attack of 51% computing power of the whole network is needed to tamper with the existing data, so that the blockchain system has the characteristics of ensuring the security and preventing the attack and tampering of the data which are incomparable with other centralized database systems. Therefore, the data recorded in the distributed database of the blockchain cannot be attacked or tampered, so that the true reliability of the data information stored in the distributed database of the blockchain is ensured.
Example types of blockchain networks may include public blockchain networks, private blockchain networks, and federated blockchain networks. Although the term blockchain is typically associated with bitcoin cryptocurrency networks, blockchain as used herein may refer to DLS (distributed ledger system) without reference to any particular use case.
In a common blockchain network, the consensus process is controlled by nodes of the consensus network. For example, hundreds, thousands, or even millions of entities may cooperate in a public blockchain network, each entity operating at least one node in the public blockchain network. Thus, a public blockchain network may be considered a public network with respect to participating entities. An example public blockchain network includes a bitcoin network, which is a peer-to-peer payment network. The bitcoin network utilizes a distributed ledger, known as a blockchain. However, as noted above, the term blockchain is generally used to refer to a distributed ledger that does not refer specifically to a bitcoin network.
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 that replicates across all nodes. That is, for a global blockchain, all nodes are in a completely consistent state. To achieve consensus (e.g., agree to add blocks to the blockchain), a consensus protocol is implemented within the common blockchain network. Example consensus protocols include, but are not limited to, proof of work (POW) implemented in bitcoin networks.
Typically, a private blockchain network is provided to a specific entity that centrally controls read and write rights. The entity controls which nodes can participate in the blockchain network. Thus, private blockchain networks are often referred to as licensed networks, which impose restrictions on who is allowed to participate in the network and its participation level (e.g., only in certain transactions). Various types of access control mechanisms may be used (e.g., existing participants vote to add new entities, and a regulatory authority may control admission).
Typically, federated blockchain networks are proprietary among the participating entities. In a federated blockchain network, the consensus process is controlled by an authorized set of nodes (federated member nodes), one or more of which are operated by a corresponding entity (e.g., an enterprise). For example, a federation consisting of ten (10) entities (e.g., enterprises) can operate a federated blockchain network in which each entity operates at least one node. Thus, a federated blockchain network may be considered a private network as far as participating entities are concerned. In some examples, each entity (node) must sign each block to make the block valid and add the valid block to the blockchain. In some examples, at least a subset of entities (nodes) (e.g., at least 7 entities) must sign each block to make the block valid and add the valid block to the blockchain.
It is contemplated that the embodiments provided herein can be implemented in any suitable type of blockchain network.
A node (or node device) as described in one or more embodiments of the present specification refers to a node that can join the blockchain by following the installation of a corresponding node protocol, running a node protocol program, as the blockchain. Those skilled in the art generally refer to node devices having a full backup of data of a blockchain distributed database as full nodes, node devices having a partial backup of data of a blockchain distributed database (e.g., data having only a block header) as light nodes, and the like. In one or more embodiments of the present disclosure, the node type of the service platform side node device is not limited. The number of the service platform node devices is not limited in the present specification, and the service platform may correspond to one device terminal or server, or may correspond to a plurality of device terminals or servers to serve as node devices of the blockchain.
The business platform described in one or more embodiments in this specification refers to a network platform that provides business service acceptance or notification for a user; the users of the business platform comprise users receiving the business service; the service provider includes an entity, typically an organization entity, for providing or supporting service for a user of the service platform through the network platform; the user of the service platform and the corresponding client of the service provider are both in communication connection with the service platform node equipment. The "business service data" described in one or more embodiments of the present disclosure may refer to consensus data (e.g., a digitized representation of a business contract) provided by a business platform to a platform user for representing the business service achieved by the business provider and the platform user.
In one or more embodiments provided in the present disclosure, a user entity and a service provider of the service platform join the blockchain network by running a client installer at a terminal, where the client installer may be an installer of a blockchain node device, and accordingly, the client also serves as a node device of the blockchain, and when backing up a distributed database copy of the blockchain, initiates a data acquisition request to a node device adjacent thereto (such as the node device on the service platform side), or issues data onto the blockchain by broadcasting data to the node device adjacent thereto; the client installer may also be a blockchain user client program that is connected to a federation member node device (e.g., the service platform node device) in a blockchain of the federation, and accordingly, the client is not typically used as a node of the blockchain because it does not have the right to directly access the blockchain's distributed database, and needs to make a data request with right learning to one or more federation member nodes connected thereto. The present specification is not limited to whether the user client and the service provider client are node devices of the blockchain.
The "service agent contract" mentioned in one or more embodiments in the present specification includes a paper service agent contract (electronic version), an electronic service agent contract, etc. signed by a service platform side and a service provider side, which is used to provide agent authority proof or compliance proof for the service data provided by the service platform side, so as to prevent the service platform side from having authority to proxy the service or the content of the service data provided by the service platform side from being inconsistent with the content specified by the service agent contract. The service agent contract is provided with a unique identification code in a distributed database of the block chain correspondingly; the identification code may be assigned to the service agent contract by the service platform side, or may be determined by the content of the service agent contract, for example, a hash digest of the service agent contract may be used as the identification code. By using the form relation of the identification code-service agent contract to store the service agent contract, the key fields of the service agent contract are convenient to extract, inquire or use.
The above-described business agent contracts may be stored in the distributed database of the blockchain in the form of "transactional" content or portions of content. Transactions (transactions) described in one or more embodiments herein refer to a piece of data created by a node device of a blockchain and that needs to be eventually published into a distributed database of the blockchain. Among the transactions in the blockchain are narrow transactions and broad transactions. A narrow transaction refers to a transfer of value issued by a user to a blockchain; for example, in a traditional bitcoin blockchain network, the transaction may be a transfer initiated by the user in the blockchain. And a generalized transaction refers to a piece of business service data with business intent that a user entity publishes to a blockchain through a node. The transaction including the service agent contract content according to this embodiment may include an original text or ciphertext of the service agent contract to authenticate the content of the service agent contract, or may include a "digital fingerprint" of the service agent contract content, that is, a hash digest of the service agent contract, as authentication data, and may function as an anti-tampering mechanism based on a blockchain to authenticate the service agent contract.
In practical business applications, the blockchain network described in one or more embodiments of the present disclosure may be configured as a federation chain, and the business platform node device is used as a federation member node device, and sends a certification transaction including the business agent contract to the federation chain. Compared with a public chain, the common algorithm adopted by the alliance chain is generally high in efficiency, and can meet the requirement of high-frequency transaction amount, such as the evidence-storing transaction of a business agent contract which is generated by frequent subscription with a business platform based on diversified business service provision of a business provider; the common time delay is very low, the real-time processing requirement is basically met, and the evidence-storing transaction can be rapidly recorded in a new block of the block chain in real time; moreover, the trusted node (such as a node corresponding to a service platform side or a government agency) in the alliance chain network is used as a preselected accounting node, so that the safety and the stability are both considered; in addition, federated chain consensus algorithms (e.g., PBFT) typically do not consume excessive computer power resources nor do they necessarily require token circulation, and thus have good usability.
In order to facilitate the business platform side to perform compliance operations such as checking, correcting and the like on business service data provided for users, the business platform node equipment configures the business service data corresponding to the business agent contracts. The correspondence between the business service data and the business agent contract may be a one-to-one correspondence, or a many-to-one correspondence, which is not limited in the present specification.
In an embodiment, the service agent contract includes a digital signature made by the service platform node device and the service provider client, so as to prevent other institutions or users from masquerading the identity forging contract of any party of the two parties, and further guarantee is provided for legal compliance of the service agent contract.
In yet another illustrated embodiment, the business agent contract is a smart contract deployed in the blockchain. To further provide context for embodiments of the present specification, in a blockchain network, applications may be developed, tested, and deployed for execution within the blockchain network. Example applications may include, but are not limited to, smart contracts. The smart contracts may be described as digital representations of real world legal contracts having contract terms that affect parties, such as business agent contracts provided by the present embodiment. The smart contracts are implemented, stored, updated (as needed), and executed within the blockchain network. Contractors (e.g., buyers and sellers) associated with the smart contract are represented as nodes in a blockchain network.
In some examples, the smart contract may store data that may be used to record information, facts, associations, balances, and any other information needed to implement the contract execution logic, such as the business agent contracts provided by the present embodiments may record specific business feature content to embody the key feature data of the business agent contracts described above. A smart contract may be described as a computer-executable program that consists of functions that may be created as instances (instances) of the smart contract, invoking functions to execute the logic of the smart contract.
In a technical aspect, a smart contract may be implemented based on objects and object-oriented classes. For example, the terms and components of a smart contract may be represented as objects that are processed by an application implementing the smart contract. A smart contract (or an object in a smart contract) may invoke another smart contract (or an object in the same smart contract) like other object-oriented objects. 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, APIs), or other calling mechanisms. For example, a first object may call a function to create a second object.
Therefore, based on the above description about the intelligent contract, in this embodiment, the logic that the service platform side and the service provider sign the service agent contract content may be written as an intelligent contract code and deployed on the blockchain after the common identification verification of the blockchain. And signing or inquiring the service agent contract is completed through the calling transaction of the service platform node equipment or the service provider client to the intelligent contract. Those skilled in the art should appreciate that the execution logic of the intelligent contract is authenticated by the consensus of the block chain point device, and the execution logic is based on a tamper-proof mechanism and a consensus mechanism of the block chain, so that the intelligent contract has the advantages of high execution efficiency (the execution result can be executed by triggering a call transaction containing encrypted data at any time), accurate execution (the execution result is authenticated by the block chain consensus), low human intervention risk (the code executed by the intelligent contract is tampered by the block chain consensus authentication), lower running cost (such as manpower cost) and the like, thereby automatically signing the logic of the business agent contract for both contract sides and signing the content of the business agent contract for both contract sides.
As shown in fig. 1, the data processing method based on blockchain provided in this embodiment includes:
The identification information of the service data may include the whole content of the service data or an identification code such as a coded serial number of the service data, so as to facilitate the user client to obtain the content information of the service data for reference, and select the target service data from at least one service data.
And 106, executing preset business acceptance logic based on the target business agent contract and the target business service data.
The business acceptance logic described in the above embodiment may include a business acceptance process such as user data acquisition, delivery, auditing of a target business service selected by a user, or signing of a target business service contract.
In yet another illustrated embodiment, the target service proxy contract includes service feature content proxieable by the service platform side; the target business service data comprise target business characteristic contents provided by the business platform side; the executing preset business acceptance logic comprises the following steps: and verifying whether the target business feature content included in the target business service data is consistent with the business feature content which can be proxied by the target business proxy contract.
In the above embodiments of the present disclosure, the target service agent may be a digital contract or a digitalized contract (for example, when the target service agent contract is a paper contract in digital picture format, the digitalized contract may be obtained by means of word recognition or the like); the service platform can perform data operation such as query, extraction, comparison and the like on the data content of the target service agent contract. Therefore, by comparing the target service feature content of the target service data provided by the service platform side with the service feature content which can be proxied by the target service agent contract, whether the two service feature contents are consistent can be verified, so that a conclusion is obtained whether the target service data accords with the contract of the target service agent or whether the target service data is effective, and the content verification of the target service data is avoided by manual work in the existing service acceptance process.
Since in the above embodiments of the present specification, the target business agent is in the form of a digitized contract or a digitized contract, the above-described process of verifying whether the target business feature content of the target business service data is consistent with the business feature content that the target business agent contract can proxy can be performed by a computer-executable program. In one illustrated embodiment, the above-described process may verify that the target business feature content included in the target business service data is consistent with the business feature content proxieable by the target business agent contract by invoking a business service data verification smart contract, executing business service data verification logic declared by the smart contract.
Optionally, the business service data verification intelligent contract and the intelligent contract corresponding to the business agent contract may be the same contract, that is, corresponding business service data verification logic is deployed for the intelligent contract corresponding to the business agent contract, and verification of the target business service data can be completed by calling the business agent intelligent contract.
Specifically, the blockchain-based data processing method provided in one or more embodiments of the present disclosure may be applied to the insurance application field, that is, the service platform node device is an insurance platform node device; the user client is an insurance user client; the service provider client is an insurance provider client; the service agent contract is a policy agent contract; the business service data are policy clause data; the preset service acceptance logic is application acceptance logic.
The insurance platform refers to a user-oriented network platform for providing an insurance service; the insurance user of the insurance platform is a person or organization entity which receives the purchase or the signing of insurance products or insurance policies on the insurance platform; the insurance provider is an organization mechanism for providing insurance service for the insurance user through an insurance platform; corresponding clients of the insurance user and the insurance provider are in communication connection with the insurance platform node equipment. An "policy" as described in one or more embodiments herein is a digitized representation of an insurance contract to be made by an insurance provider with an insuring user.
The "insurance agency contract" includes paper contracts (electronic version) and electronic contracts signed by the insurance platform side and the insurance provider, and is used for providing compliance certification for insurance products or insurance forms provided by the insurance platform, and preventing the insurance platform from unauthorized agency of the insurance forms or the content of the agency insurance forms from being inconsistent with the content specified by the insurance agency contract. The policy agent contract corresponds to a unique identification code in a distributed database of the blockchain; the identification code may be assigned to the policy agent contract by an insurance platform, or may be determined by the policy agent contract, for example, a hash digest of the policy agent contract may be used as the identification code. The key fields of the policy agent contract are conveniently extracted, queried or used by using the form relation of the identification code-policy agent contract to store the policy agent contract.
Accordingly, as shown in fig. 2, the block chain-based application acceptance method executed by the insurance platform node device includes:
The identification information of the policy may include all contents of the policy, or identification codes such as serial numbers of the policy, so as to facilitate the client of the insurance user to obtain the content information of the policy for review, and select a target policy to be insurance from at least one policy.
and step 203, executing preset application acceptance logic based on the target policy agent contract and the target inclusion.
The above-mentioned application acceptance logic may include application business processes such as acquisition, transmission, or verification of the user, acceptance of the result, or signing of the insurance contract.
In yet another illustrated embodiment, the service proxy contract includes a digital signature made by the platform node device and the service provider client.
In yet another illustrated embodiment, the business agent contract is a smart contract deployed at the blockchain.
In an embodiment, the target policy agent contract includes policy feature content that the insurance platform can agent, where the policy feature content is used to represent key feature information of a policy, such as premium, or premium or risk content. Since in the above embodiments of the present specification, the target policy agent is about a digitized contract or a digitalized contract (for example, when the target policy agent contract is a paper contract in digital picture format, the digitalized contract may be obtained by means of word recognition or the like); the insurance platform can perform data operations such as inquiring, extracting, comparing and the like on the data content of the target policy agency contract. Therefore, by comparing the characteristic contents of the policy of the target policy provided by the insurance platform with the characteristic contents of the policy which can be proxied by the target policy proxy contract, whether the characteristic contents of the two policies are consistent can be verified, so that a conclusion is obtained whether the target policy accords with the contract of the target proxy contract or whether the target policy is effective, and the content verification of the target policy is avoided by manual work in the existing application and insurance acceptance process.
Since the target policy agent is about a digitized contract or a digitized contract in the above embodiments of the present specification, the above-described process of verifying whether the policy feature content of the target policy is consistent with the policy feature content that the target policy agent contract can agent can be executed by a computer-executable program. In one illustrated embodiment, the above-described process may verify whether the policy feature content of the target policy is consistent with the policy feature content that the target policy agent contract may proxy by invoking a policy verification smart contract, executing the policy verification logic of the smart contract statement.
Optionally, the policy verifying intelligent contract may be the same contract as the intelligent contract corresponding to the policy agency contract, that is, a corresponding policy verifying logic is deployed for the intelligent contract corresponding to the policy agency contract, and verification of the target policy may be completed by calling the policy agency intelligent contract.
