First, terms used in the present disclosure are introduced.
Block chains: a decentralized distributed database is a novel application mode based on technologies such as P2P network transmission, a consensus mechanism, an encryption algorithm and the like. The blockchain utilizes a chain data structure to store and verify data, utilizes cryptography to secure data transmission and querying, and utilizes intelligent contracts to manipulate data.
Channel of blockchain: there may be multiple channels in a blockchain, and the nodes within each channel may achieve consensus on the data within that channel.
And (3) node: each device (server) connected to the blockchain may correspond to a respective enterprise, organization, etc. in embodiments of the present invention.
The following describes a block chain-based information processing method and apparatus according to an embodiment of the present disclosure in detail.
Fig. 1 is a flowchart illustrating a block chain-based information processing method according to an exemplary embodiment.
As shown in fig. 1, in S110, transaction information between the first node and other nodes is acquired.
According to the embodiment of the invention, the transaction information of the first node and other nodes can comprise contracts, orders, goods receiving and dispatching data, settlement data, fund traffic data and the like which are signed between the first node and other nodes. For example, the first node may be an enterprise, an organization, etc., and the other nodes with which the transaction information exists may be the suppliers of the enterprise (organization).
It is noted that the first node may have transaction information with at least one of the other nodes. For example, when the first node is a core enterprise, the transaction information may be the goods receiving and dispatching information between the core enterprise and the suppliers and logistics companies.
In S120, the transaction information is encapsulated to generate data for one of a plurality of channels of a trade block chain of a data pool.
According to the embodiment of the invention, a data pool is arranged at the first node, and the data pool can comprise a plurality of block chains, such as a trade block chain, a data block chain and an audit block chain, and different data are stored in each block chain.
It should be noted that the trade block chain in the embodiment of the present invention may include a plurality of channels, and the transaction data of the first node and each of the other nodes are encapsulated in one channel. For example, the transaction information of the first node and the node a is packaged in the first channel of the trade block chain, and the transaction information of the first node and the node B is packaged in the second channel of the trade block chain.
It should be noted that the data blockchain and the audit blockchain in the data pool may have the same structure as the trade blockchain or may have different structures from the trade blockchain.
According to the embodiment of the present invention, the data block chain may be encapsulated with the ledger information of the first node. For example, the ledger information may include income information, expenditure information, and the like of the first node, which belong to privacy information of the enterprise and are not commonly known to other nodes. It should be noted that, if there is only one node in the blockchain, the information in the blockchain is not commonly recognized to other nodes, and the common recognition between different blockchains cannot be realized.
According to the embodiment of the invention, the audit block chain can be packaged with operation information of the trade block chain and the data block chain. For example, when a first node writes transaction information between the first node and the node B in the trade blockchain, operation information of the first node writing the transaction information between the first node and the node B in the blockchain can be recorded in the audit blockchain.
It should be noted that when other nodes are added to the audit block chain, the consensus on the operation information of the trade block chain and the data block chain can be realized with the other nodes. For example, when the first node is a core enterprise and needs to perform financing activities with some financial institutions subsequently, the financial institutions may be added to the audit block chain, so that the financial institutions are aware of information on the audit block chain, thereby increasing the credibility of the core enterprise.
According to the embodiment of the invention, on one hand, the transaction information can be directly packaged to generate the data of one of the plurality of channels of the trade block chain of the data pool, and on the other hand, the link address of the transaction information can also be packaged to generate the data of one of the plurality of channels of the trade block chain of the data pool.
In S130, data of a channel of the trade block chain is disclosed on the channel to provide an information query service.
According to the embodiment of the invention, after the data of the channel is disclosed on the channel of the trade block chain, the data is identified among the nodes on the channel, and the information query service is provided.
In the embodiment of the invention, transaction information between a first node and other nodes is acquired; packaging the transaction information to generate data for one of a plurality of channels of a trade block chain of a data pool; and disclosing the data of the channel on the channel of the trade block chain to provide information inquiry service. The problems that in the information interaction process between an existing enterprise and a third-party organization, efficiency is low, expansibility is poor, sharing cannot be achieved, unauthorized access and data leakage cannot be guaranteed difficultly, and data are maliciously tampered and forged are solved.

According to the embodiment of the invention, after the data pool comprising the trade block chain is constructed, the node corresponding to each channel in the trade block chain can send a financing request to some other nodes (such as financial institutions), wherein the financing request can comprise a transaction information summary, and when the other nodes need to inquire transaction information, an inquiry request containing the transaction information summary is sent to the first node.
For example, fig. 3 is a diagram illustrating an application of a blockchain-based information query, according to an example embodiment. As shown in fig. 3, the first node is a core enterprise, and the ERP of the core enterprise writes data into the data pool through the data pool interface. The data pool may include a plurality of block chains, such as an audit block chain in which an audit book is stored, a data block chain in which a data book is stored, and a trade block chain in which transaction information (book) is stored. A node of a certain provider is added to a certain channel of the trade block chain in the data pool of the core enterprise, it should be noted that the provider may also have its own data pool, and the data pool may also include a plurality of block chains. Generally, when the supplier does not receive payment from the core enterprise, the supplier needs to initiate a financing request to the financial institution, and if the financial institution is interested in the financing request of the supplier, an inquiry request containing a summary of transaction information can be sent to the trade blockchain on the first node to obtain authorization to view the transaction information on the trade blockchain.
It should be noted that the financing request may also be initiated by the first node, and the financing request includes a summary of the transaction information between the first node and the node a, based on which the financial institution X sends a query request including the summary of the transaction information to the blockchain.
According to the embodiment of the invention, if the financing request sent by one of the other nodes includes an unauthorized transaction information summary, the requester needs to send an authorization request of the transaction information summary to the first node (or the node sending the financing request), if the first node and the node sending the financing request are both authorized, the first node or the node sending the financing request returns an authorization response, and after receiving the authorization response, the requester sends a request containing the transaction information summary to the first node or the node sending the financing request.
According to the embodiment of the invention, before inquiring the transaction information corresponding to the transaction information abstract from the channel of the trade block chain, the first node may receive an authorization request of the transaction information sent by the requester, and after returning an authorization response to the requester, inquire the transaction information corresponding to the transaction information abstract from the channel of the trade block chain.
In S220, the transaction information corresponding to the transaction information summary is queried from the channel of the trade block chain.
According to the embodiment of the invention, after receiving the query request containing the transaction information abstract, the transaction information corresponding to the transaction information abstract can be queried from the trade block chain.
In S230, the transaction information is returned to the requestor.
According to the implementation of the invention, if the transaction information is stored in the channel of the trade block chain, the transaction information can be returned to the requesting party, or if the link of the transaction information is stored in the channel of the trade block chain, the link can be returned to the requesting party, so that the requesting party obtains the transaction information according to the link.
