Description

Intelligent contract triggering method and device applied to block chain network and related equipment

Technical Field

The present disclosure relates to the field of computer and internet technologies, and in particular, to an intelligent contract triggering method and apparatus, an electronic device, and a computer-readable storage medium for a block chain network.

Background

The block chain technology is also called as distributed ledger technology, and is a distributed internet database technology. A network constructed based on the blockchain technology may be referred to as a blockchain network, where the blockchain network includes network nodes (also referred to as blockchain nodes, hereinafter referred to as nodes), and node devices corresponding to each node store a total number of blockchains. The blockchain network (or blockchain technology) in the related art has the characteristics of decentralization, public transparency, non-tampering, trustiness and the like. Based on these characteristics, the application field of the block chain technology is more and more extensive.

In the related art, it is often necessary to arrange an intelligent contract in a blockchain network to process data in the blockchain network. A conventional smart contract is a piece of code or program deployed at an address in a blockchain, the smart contract has a call address in the chain, and the smart contract can be executed only if a node device actively calls the smart contract through the call address.

However, the above intelligent contract triggering method causes the security performance of uplink data to be low and the public trust to be poor.

It is to be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present disclosure.

The embodiments of the present disclosure relate to a blockchain technology, and the following description will be directed to a blockchain network, a blockchain, a node, and the like in the blockchain technology.

The embodiment of the disclosure relates to an intelligent contract triggering method applied to a blockchain network, which may be a blockchain network formed by connecting a client, a plurality of nodes (any form of computing devices in an access network, such as servers and terminals) through a network communication form.

The server may be an independent physical server, or may be a cloud server that provides basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, a middleware service, a domain name service, a security service, a CDN, and a big data and artificial intelligence platform, and the like, which is not limited in this disclosure.

The user can perform data interaction with the blockchain through the client, and the blockchain network system can perform consensus, business processing, recording and the like on data uploaded by the user through nodes.

Taking a distributed blockchain network as an example, referring To fig. 3, fig. 3 is an optional structural schematic diagram of a blockchain network 301 provided in the embodiment of the present disclosure, and is formed by a plurality of nodes 302 (any form of computing devices in an access network, such as servers and terminals) and a client 303, a Peer-To-Peer (P2P) network is formed between the nodes 302, and the P2P Protocol is an application layer Protocol operating on a Transmission Control Protocol (TCP). In a blockchain network, any machine, such as a server, a terminal, can join to become a node 302, and the node 302 includes a hardware layer, a middle layer, an operating system layer, and an application layer.

Referring to the functions of each node 302 in the blockchain network 301 shown in fig. 3, the functions involved include:

1) routing, a basic function that node 302 has, is to support communication between nodes 302.

Besides the routing function, the node may also have the following functions:

2) the application is used for being deployed in a block chain, realizing specific services according to actual service requirements, recording data related to the realization function to form recording data, carrying a digital signature in the recording data to represent a source of task data, and sending the recording data to other nodes in the block chain network, so that the other nodes add the recording data to a temporary block when the source and integrity of the recording data are verified successfully.

For example, the services implemented by the application include:

an intelligent contract, a computerized agreement, which can execute the terms of a certain contract, is realized by codes deployed on a shared account and executed when a certain condition is met, and is used for completing automated transaction according to actual business requirement codes, such as inquiring the logistics state of goods purchased by a buyer and transferring the electronic resources of the buyer to the address of a merchant after the buyer signs the goods; of course, the smart contract may be not only a contract for trading but also a contract for business processing of received information. In the related art, usually, a node device actively calls an intelligent contract to process data requesting an uplink blockchain or data already stored on the blockchain, and in the intelligent contract triggering mechanism, there may be a case where the node device refuses to call the intelligent contract, resulting in low public trust of the data in the blockchain. The technical scheme provided by the embodiment has the main improvement points that the target intelligent contract matched with the target transaction data attribute information is actively matched and triggered to process the target transaction data, the condition that the node equipment refuses to call the contract is avoided, and the security during data chaining is improved.

3) And the Block chain comprises a series of blocks (blocks) which are mutually connected according to the generated chronological order, new blocks cannot be removed once being added into the Block chain, and recorded data submitted by nodes in the Block chain network are recorded in the blocks.

Referring to fig. 4, fig. 4 is an optional schematic diagram of a Block Structure (Block Structure) provided in the embodiment of the present disclosure, where each Block includes a hash value of a transaction record stored in the Block (hash value of the Block) and a hash value of a previous Block, and the blocks are connected by the hash values to form a Block chain. The block may include information such as a time stamp at the time of block generation. A block chain (Blockchain), which is essentially a decentralized database, is a string of data blocks associated by using cryptography, and each data block contains related information for verifying the validity (anti-counterfeiting) of the information and generating a next block.

In the disclosed embodiment, after the target intelligent contract matched with the attribute information of the target transaction data is automatically triggered by the method of the disclosed embodiment to automatically execute the target intelligent contract for the target transaction data, the target transaction data corresponding to the target transaction may be stored in the target block to complete the target transaction.

According to the technical scheme provided by the embodiment, on one hand, the target intelligent contract matched with the attribute information of the target transaction data is determined, and the target transaction data can be processed in a targeted manner through the target intelligent contract; on the other hand, the intelligent contract is automatically triggered aiming at the target transaction data, so that the condition that the node equipment refuses to call the intelligent contract is avoided, and the public trust and the safety of the target transaction data are improved.

Fig. 5 is a flowchart illustrating an intelligent contract triggering method applied to a blockchain network in accordance with an exemplary embodiment. The method may be performed by a target node device in a blockchain network.

In the blockchain technique, the blockchain network may include a plurality of node devices, each of which may have a full number of blockchains stored therein. As shown in fig. 6, the blockchain network 10 may include a plurality of node devices (e.g., node device 101, node device 102 … node device 150, etc.), which may belong to a national department, an individual, or a business, etc., each of which has a complete blockchain stored therein.

In addition, each node device in the block chain network may also be deployed with at least one intelligent contract (such as intelligent contract 1, intelligent contract 2, and intelligent contract 3 … shown in fig. 6), where the at least one intelligent contract may exist in the node device independently from each other, or may exist in the node device in a hierarchical manner. Where an intelligent contract may be contract content deployed by a piece of code or program on a blockchain, the blockchain network may execute the intelligent contract through a target node device (e.g., node device 101 in fig. 6) to implement processing of target transaction data. The target node device may refer to a common node device of a blockchain network in a common processing process, or may be a transaction processing device of a blockchain in a service transaction processing process for target transaction data (i.e., a node for processing transaction content in a target transaction), which is not limited in this disclosure. It is understood that any node device that processes a target transaction through an intelligent contract in a blockchain network may be a target node device in the embodiments of the present disclosure.

In some embodiments, the target node device may be any electronic device with computing processing capability in a blockchain network, and the electronic device with computing processing capability may be, for example, a server or a terminal device.

In addition, it should be noted that the intelligent contract triggering method provided in the embodiment of the present disclosure may be applied to both the data uplink process and any application scenario that needs to trigger an intelligent contract after the data uplink is finished (i.e. the data is already recorded in the block chain), and the disclosure does not limit this.

The intelligent contract triggering method applied to the blockchain network provided by the embodiment of the disclosure with reference to fig. 5 can include the following steps.

In step S1, attribute information of the target transaction data is acquired.

In some embodiments, the transaction data may refer to data being linked in a blockchain, and may also refer to data already stored in a target blockchain, which is not limited by the present disclosure. It will be appreciated that the target transaction data is transaction data corresponding to a target transaction, which is data used to describe the target transaction.

The attribute information of the target transaction data may refer to information used to describe an abstract characteristic of the target transaction, for example, the attribute information of the target transaction data may include a transaction type, a business field, a transaction name, transaction content information, and the like corresponding to the target transaction to which the target transaction data relates, which is not limited in this disclosure. Wherein the target transaction data may be transaction data of the target transaction.

In some embodiments, the transaction types of the target transaction data may include an asset transfer transaction type, an asset issuance transaction type, and the like.

Where an asset may refer to some electronic resource in a target block chain, this disclosure is not limited thereto.

In step S2, a target intelligent contract matching the attribute information of the target transaction data is obtained from the blockchain network.

The target intelligent contract is an intelligent contract which can be checked or business-processed against the target transaction data. The verification may refer to consensus verification or common service verification, which is not limited by this disclosure. The business processing may refer to business processing of the transaction content related to the target transaction data, for example, specific business processing (for example, business processing for controlling transfer from bank a to bank B) is performed on the target transaction data, and the content of the target intelligent contract is not limited by the present disclosure.

In some embodiments, obtaining the target intelligent contract matching the attribute information of the target transaction data from the blockchain network may refer to matching the attribute information of the target transaction data with the intelligent contract in the blockchain network through a target rule. For example, if the target transaction is indicated as the asset transfer transaction type by the transaction type information according to the attribute information of the target transaction data, the intelligent contract that processes the asset transfer type data may be used as the target intelligent contract. The target rule may be formulated in advance according to the attribute information, which is not limited by the present disclosure.

In step S3, the target intelligent contract is triggered to execute the target intelligent contract against the target transaction data.

In some embodiments, after the target intelligent contract is matched according to the attribute information of the target transaction data, the target intelligent contract can be automatically executed aiming at the target transaction data.

The technical scheme provided by the embodiment can match the target intelligent contract matched with the attribute information of the target transaction data, and automatically trigger the target intelligent contract to process the target transaction data. According to the technical scheme provided by the embodiment, when the intelligent contract needs to be triggered, the target node equipment can automatically execute the target intelligent contract matched with the attribute information of the target transaction data, actively completes verification or related business processing of the target transaction data, and improves the safety and the public trust of the block chain.

In some embodiments, the target transaction data is transaction data of a target transaction, and the at least one intelligent contract in the blockchain network may include an asset issuing intelligent contract that may include contract information that enables verification of asset issuing information in the target transaction.

Referring to fig. 7, the above-described intelligent contract triggering method applied to the blockchain network may include the following procedures.

In step S1, attribute information of target transaction data including transaction type information is acquired.

In step S21, if the transaction type information indicates that the target transaction is an asset issuance transaction type, the asset issuance intelligent contract is obtained from the blockchain network.

In step S31, the asset issuance smart contract is automatically triggered to verify the asset issuance information in the target transaction data by the asset issuance smart contract.

In some embodiments, verification of asset issuance information in a target transaction may be accomplished by the steps shown in FIG. 8.

Fig. 8 is a flowchart of step S31 in fig. 7 in an exemplary embodiment.

In some embodiments, the asset issuance information in the target transaction data may include information relating to the issuance of assets for the target transaction, such as a first blockchain address at which the target transaction was initiated, the first blockchain address being for the quantity of assets to be issued for the target transaction. Wherein the amount of assets to be issued may refer to assets issued by the first blockchain address as rewards to node devices that are billed for the target transaction data.

In some embodiments, the asset issuance intelligent contract may be composed of hierarchical sub-contracts, e.g., the asset issuance intelligent contract may include an asset issuance authority verification sub-contract, the asset issuance authority verification sub-contract may include an asset issuance amount control sub-contract, etc. It will be appreciated that the next level of the asset issuance amount control grandchild contract may also include other contract content, and the disclosure is not limited thereto.

Referring to fig. 8, the above-described step S31 may include the following process.

In step S311, the asset issuance authority of the first blockchain address is verified by the asset issuance authority verification sub-contract.

In some embodiments, if the transaction type information in the attribute information indicates that the transaction type of the target transaction is an asset issuance transaction type, the asset issuance authority verification sub-contract is automatically triggered to verify the asset issuance authority of the first blockchain address. For example, it can be verified whether the first blockchain has the asset issuance authority by the public-private key of the first blockchain address.

In step S312, if the asset issuance authority of the first blockchain address passes the verification, it is verified whether the quantity of the assets to be issued is less than or equal to the preset target quantity through the asset issuance quantity control grandchild contract.

In some embodiments, if the asset issuance authority of the first blockchain is verified, the verification of whether the first blockchain address is less than or equal to the preset number for the number of assets to be issued in the target transaction is continued through the asset issuance volume control grandchild contract. The preset target quantity may refer to a quantity of the assets issued at most per transaction in the asset issuance amount control grandchild contract, which is preset.

In some embodiments, the target node device fails validation of the target transaction data if the asset issuance authority validation of the first blockchain fails.

In step S313, if the number of assets to be issued is less than or equal to the preset target number, it is determined that the target transaction data passes verification.

In some embodiments, if the number of assets to be issued is less than or equal to the preset target number, the target node device passes verification on the target transaction data.

It is understood that the asset issuance smart contract may include not only verification information that can verify the asset issuance information in the target transaction data, but also processing information that can perform business processing for a specific business in the target transaction data (e.g., processing information that deducts a tax for income funds related to the target transaction data). Therefore, after the verification of the asset issuance information for the target transaction data is completed, other contract contents in the asset issuance intelligent contract may also be executed continuously according to other attributes in the target transaction data, which is not limited by the present disclosure.

According to the technical scheme provided by the embodiment, the asset issuing authority of the first block chain address, the asset issuing quantity aiming at the target transaction and the like are verified by automatically triggering the asset issuing intelligent contract, so that the asset issuing behavior of the first block chain is reasonable and legal, and the safety and the public trust of the block chain are improved.

In some embodiments, the target transaction data is transaction data of a target transaction, and the at least one intelligent contract in the blockchain network may include an asset transfer intelligent contract that may enable verification of asset transfer information in the target transaction.

In step S1, attribute information of target transaction data including a transaction type is acquired.

In step S22, if the transaction type information indicates that the target transaction is an asset transfer transaction type, the asset transfer intelligent contract is obtained from the blockchain network.

In step S32, the asset transfer intelligence contract is automatically triggered to validate asset transfer information in the target transaction data by the asset transfer intelligence contract.

In some embodiments, verification of asset transfer information in a target transaction may be accomplished by the steps shown in FIG. 10.

Fig. 10 is a flowchart of step S32 in fig. 9 in an exemplary embodiment.

In some embodiments, the asset transfer information may include information related to the transfer of assets for the target transaction, including, for example, a second blockchain address at which the target transaction was initiated, a quantity of assets to be transferred for the target transaction at the second blockchain address. Wherein the amount of assets to be transferred may refer to assets transferred as rewards to the node that billed for the target transaction data by the second blockchain address.

In some embodiments, the asset transfer smart contracts may be composed of a hierarchy of sub-contracts, e.g., an asset transfer smart contract may include an asset availability verification sub-contract, which may include an asset transfer amount verification grandchild contract. It will be appreciated that the next level of asset transfer amount validation grandchild contracts may also include other contract content, and the disclosure is not limited thereto.

Referring to fig. 10, the above step S32 may include the following process.

In step S321, it is verified whether the remaining amount of assets of the second blockchain address is greater than or equal to the number of assets to be transferred by the asset remaining amount verification sub-contract.

In some embodiments, the asset balance verification self-contract is automatically triggered to verify the balance of assets in the second blockchain address if the target transaction is an asset transfer type transaction.

In step S322, if the remaining amount of assets of the second block chain address is greater than or equal to the amount of assets to be transferred, verifying whether the amount of assets to be transferred is within a preset asset transfer range by using an asset transfer amount verification grandchild contract.

In some embodiments, if the remaining amount of assets of the second blockchain address is greater than or equal to the amount of assets to be transferred (i.e., it is determined that the second blockchain address does have enough assets to perform asset transfer), it is continuously verified whether the amount of assets to be transferred is within the preset transfer asset range by the asset transfer amount verification grandchild contract. The preset transfer asset range may refer to a maximum range of each asset transfer set in advance.

In some embodiments, if the remaining amount of assets of the second blockchain address is less than the amount of assets to be transferred (i.e., it is determined that the second blockchain address does not have sufficient assets to perform the asset transfer), the target node device fails verification for the target transaction.

In step S323, if the number of the assets to be transferred is within the preset asset transfer range, it is determined that the target transaction data passes verification.

In some embodiments, if the number of assets to be transferred is within a preset asset range, the target node device passes verification on the target transaction data.

It is to be understood that the asset transfer intelligent contract may include not only verification information that may enable verification of asset transfer data in the target transaction data, but also processing information that may enable business processing for a specific business in the target transaction data (e.g., processing information that may tax revenue funds involved in the target transaction data). Therefore, after the verification of the asset transfer information for the target transaction data is completed, other contract contents in the asset transfer intelligent contract can be continuously executed according to other attribute information of the target transaction data, which is not limited by the disclosure.

According to the technical scheme provided by the embodiment, the asset surplus of the second block chain address and the quantity of assets to be transferred aiming at the target transaction data are verified through automatically triggering the asset transfer intelligent contract, the legality of the target transaction data is actively verified and supervised, and the safety and the public trust of the block chain are improved.

In some embodiments, the blockchain network may be a blockchain network for multiple service domains, i.e., the blockchain may store data of multiple service domains. For example, a blockchain network may store tax business domain data, insurance business domain data, and public security business domain data simultaneously.

For the above situation, the intelligent contracts in the blockchain network may be divided according to the business domain.

In some embodiments, at least one intelligent contract in the blockchain network may include a target business intelligent contract (e.g., an intelligent contract for tax domain data) that includes the target intelligent contract, the attribute information for the target transaction data further including business domain information for the target transaction data.

Referring to fig. 11, the intelligent contract triggering method applied to the block chain network described above may include the following.

Optionally, the attribute information of the target transaction data includes transaction type information and service domain information. At least one intelligent contract comprises a target business intelligent contract comprising the target intelligent contract.

In step S23, if the service domain information of the target transaction data indicates that the target transaction data is target service data, and the target service data is supervised by a target supervising entity, a target service intelligent contract corresponding to the target supervising entity is obtained from the block chain network.

In some embodiments, a target business intelligence contract matching the target transaction data may be obtained from the blockchain network according to the business domain information. For example, if the service domain information of the target transaction data indicates that the target transaction data is target service data (e.g., tax data) which is supervised by a target supervising authority (e.g., tax authority), a target service intelligent contract corresponding to the target supervising authority is obtained from the block chain network. The target business intelligence contract may also include a target intelligence contract that may be divided into an asset issuance intelligence contract and an asset transfer intelligence contract by transaction type.

In step S24, a target intelligent contract matching the transaction type of the target transaction data is obtained from the target business intelligent contract.

In some embodiments, if the asset reward behavior corresponding to the target transaction is asset issued, acquiring an asset issuing intelligent contract from the target service intelligent contract; and if the asset reward behavior corresponding to the target transaction is asset transfer, acquiring an asset transfer intelligent contract from the target service intelligent contract.

In step S33, the target business intelligence contract is automatically triggered to automatically execute the target business intelligence contract to verify whether the target transaction data is in compliance.

In some embodiments, the target transaction data may be subjected to compliance verification according to the regulatory requirements of different regulatory agencies, for example, whether the target transaction data conforms to relevant laws and regulations, whether sensitive words exist in the target transaction data, and the like, which is not limited by the present disclosure.

In step S34, the target intelligent contract is automatically triggered to execute the target intelligent contract against the target transaction data.

In some embodiments, if the transaction type of the target transaction is an asset issuance transaction type, the target intelligent contract is an asset issuance intelligent contract, and the asset issuance intelligent contract is automatically triggered to verify the target transaction data.

In some embodiments, if the transaction type of the target transaction is an asset transfer transaction type, then the target smart contract is an asset transfer smart contract, and then the asset transfer smart contract is automatically triggered to validate the target transaction data.

According to the technical scheme provided by the embodiment, the target business intelligent contract capable of monitoring and processing the target transaction data is determined through the business field information of the target transaction data, the target business intelligent contract is automatically executed aiming at the target transaction data, the transaction content of the target transaction can be processed in a targeted mode, and the monitoring and processing strength and the processing efficiency of the block chain network on the target transaction data are improved.

In some embodiments, the intelligent contract triggering method applied to the blockchain network provided by the embodiments of the present disclosure may be applied to a consensus process of a blockchain. The specific structure and process can be taken from the following examples.

As shown in fig. 12, the node device 101 is a target node device for a target transaction, and at least one intelligent contract (e.g., intelligent contract 1, intelligent contract 2, intelligent contract 3 … intelligent contract N, N being a positive integer) is stored in the target node device 101.

When a transaction request of a target transaction in a blockchain network is detected, the target node device 101 acquires attribute information of target transaction data; the target node apparatus 101 also acquires a target intelligent contract (which may be, for example, an intelligent contract 1) matching attribute information (for example, a transaction type) of the target transaction data from the blockchain network; finally, the target node equipment automatically and actively triggers the target intelligent contract to verify the target transaction data; when the target transaction data passes the verification, the target transaction can be continuously executed.

According to the technical scheme provided by the embodiment, the target intelligent contract matched with the attribute information of the target transaction data is automatically matched in response to the transaction request of the target transaction, and the target intelligent contract is automatically triggered to process the target transaction data. According to the technical scheme provided by the embodiment, when the target transaction occurs, the target node equipment can automatically execute the intelligent contract matched with the attribute information of the target transaction data so as to actively process the target transaction data, and the safety and the public trust of the block chain are improved.

In the related art, the procedure of block chain data uplink (i.e. stored in the block chain network) includes at least three stages: an acceptance phase, a consensus phase and a storage phase.
