Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
An exemplary embodiment of the present disclosure first provides a resource request method based on a block chain. Fig. 1 shows a schematic architecture of the blockchain system. As shown in fig. 1, the blockchain 100 may include a plurality of nodes (101, 102, 103, 104 … …), wherein each node (101, 102, 103, 104 … …) is peer-to-peer, and the numbers 101, 102, 103, 104 are used merely as labels and do not limit the order of the nodes. The exemplary embodiment can be applied to a financing transaction scenario, each node (101, 102, 103, 104 … …) can be a terminal or a server of multiple participants in the financing transaction process, such as a financing transaction demand party, a financing transaction platform party, a financing transaction funding party, a supervision party, an authoritative party, a credit investigation party, an electronic sign system party or a real-name system party, and the like, and the financing transaction can be performed based on a mechanism preset in the block chain 100; the exemplary embodiment can also be applied to the supply management of enterprise resources, and each node (101, 102, 103, 104 … …) can be a terminal or a server of each production line of each branch company, each warehousing site and the like in the enterprise.
Since the blockchain 100 can be applied in scenarios such as financing transaction, considering that the nature of some resources, such as funds or important goods, is usually more valuable and private, the blockchain 100 can be a federation chain or a private chain, and the joining of each node (101, 102, 103, 104 … …) needs to satisfy certain conditions, such as authentication, authorization authentication, consensus mechanism, and so on.
In this exemplary embodiment, the execution subject of the resource request method based on the blockchain is any resource request node in the blockchain, where the resource request node is a party that needs to be provided with resources, for example, in a financing transaction, a terminal or a server of any financing transaction funding party may execute the method of this exemplary embodiment. Accordingly, the resource providing node is a party providing the resource, such as a terminal or a server of a funding party of the financing transaction.
the exemplary embodiment is further described with reference to fig. 2, and as shown in fig. 2, the resource request method based on the block chain may include the following steps S210 to S230:
Step S210, issuing a resource request in the blockchain, so that a target resource providing node in the at least one resource providing node sends feedback information in response to the resource request.
The resource request refers to application information about resource demand sent by the resource request node to other nodes, and may include information about the type, time, demand amount, and the like of a required resource, for example, in a financing transaction scenario, a financing transaction demand side sends a financing request to a financing transaction funding side, and the financing request includes a required financing amount, financing time, repayment time, and the like. The resource requesting node may write the resource request into the blockchain so that all nodes in the blockchain may receive the resource request. The resource providing node is a node where a participant for providing resources is located, such as a financing transaction funding party, and in a resource application process, at least one resource providing node may be included in a block chain, and a relationship between one or more resource providing nodes and a resource requesting node is determined according to requirements of the resource providing node and the resource requesting node, where the resource providing node that is finally determined for providing resources to the resource requesting node is a target resource providing node. In this exemplary embodiment, after receiving the resource request, the target resource providing node may issue feedback information to the blockchain, so that the resource requesting node receives the feedback information, thereby establishing a relationship between the resource providing node and the resource requesting node. The feedback information may be confirmation information that the resource providing node receives the resource request sent by the resource requesting node, or may be other request information that is initiated to the resource requesting node according to the received resource request, such as a credit acquisition request or a service data acquisition request related to the resource requesting node, so that the resource providing node determines whether to establish an association with the resource requesting node according to the information.
Step S220, in response to receiving the feedback information, establishing a resource request protocol with the target resource providing node through a pre-configured intelligent contract on the block chain.
In a blockchain, a smart contract is a computer protocol that propagates, verifies, or performs certain operations in an informational manner, for example, both trading contracts and repayment contracts during financing transactions can be considered as smart contracts, which allow trusted transaction behaviors to be conducted without a third party, and which can be traced and irreversible. It may be manually pre-configured, such as pre-configuring a contract on financing conditions for a financing transaction demander or financing transaction funder, arranging for the financing transaction funder to provide funds according to the contract. The intelligent contract can reduce the influence caused by manual intervention in the resource application process. In this exemplary embodiment, after receiving the feedback information, the resource providing node may establish a resource request protocol with the target resource providing node through the intelligent contract. The resource request agreement refers to a relationship which is established between the resource providing node and the resource requesting node and is approved by both parties, and can be represented as a specific contract which is jointly signed by the resource providing node and the resource requesting node, for example, a financing cooperation agreement which is established between a financing transaction demand party and an easy-transaction fund party in the financing transaction process and comprises financing amount, financing time, cooperation content or specific terms and the like.
Step S230, obtaining the resource provided by the target resource providing node through the resource request protocol.
after the resource request protocol is established between the resource request node and the resource providing node, the resource provided by the target resource providing node can be obtained according to the resource request protocol. For example, after the financing transaction funding party and the financing transaction demand party establish the financing cooperation agreement, the financing transaction funding party can provide funds for the easy-to-trade demand party according to the financing amount determined by the financing cooperation agreement, the financing transaction demand party can return funds to the easy-to-trade funding party according to the agreed repayment time, and the like.
Based on the above description, in the present exemplary embodiment, a resource request is issued in a blockchain, a target resource providing node in at least one resource providing node is caused to send feedback information in response to the resource request, a resource request protocol is established with the target resource providing node through a pre-configured intelligent contract on the blockchain in response to receiving the feedback information, and a resource provided by the target resource providing node is acquired through the resource request protocol. On one hand, each node in the block chain can realize information sharing in the resource request process, and the safety of information storage is improved; on the other hand, compared with the prior art, the resource application method based on the block chain can realize 'decentralized', the resource request node and the target resource providing node can directly establish an effective and open resource request protocol through the block chain, the resource application efficiency is higher, and the credibility is realized; on the other hand, the block chain can ensure that the written resource application data is not tampered, and has traceability, thereby further ensuring the security of the resource application.
in an exemplary embodiment, the feedback information in step S210 may include a credit acquisition request for the resource request node; step S220 may include the steps of:
Responding to the received feedback information, providing credit investigation data of the resource request node according to the credit investigation acquisition request, and enabling the target resource providing node to judge whether the resource request is approved or not according to the credit investigation data;
And responding to the received information of the audit passing, and establishing a resource request protocol with the target resource providing node through a pre-configured intelligent contract on the block chain.
in order to enhance the credibility of the resource requesting node and ensure the security of the resource providing node, in the exemplary embodiment, the target resource providing node may send feedback information including a credit investigation acquisition request for the resource requesting node to the resource requesting node through the block chain, so that the resource requesting node can send credit investigation data about the application node to the target resource providing node after receiving the feedback information. The credit data refers to data capable of reflecting credit of the resource request node, for example, when the financing transaction demand party is an enterprise, the credit data may be a credit report, a credit evaluation of the enterprise, or a permeable line, a credit line, etc. of the enterprise. The target resource providing node can determine whether to provide resources or how much resources by analyzing the credit investigation data of the resource requesting node, for example, a financing transaction funding party performs auditing through the credit investigation data of a financing transaction demand party, determines that financing transaction can be performed with the financing transaction funding party, and determines the specific quota, interest rate, repayment deadline and the like of the financing transaction. In the exemplary embodiment, after the credit investigation data of the target resource providing node to the resource requesting node is approved, the approved information may be sent to the resource requesting node to establish a resource request protocol therewith. In the exemplary embodiment, the resource information determined by the target resource providing node, such as the contents of financing amount, interest rate or repayment time, may be written into the intelligent contract of the current resource application, and the intelligent contract may be written into the block chain through a consensus mechanism of the block chain, so that other participating nodes may confirm the specific details of the current resource request process.
in addition, in order to further ensure the authenticity and reliability of the resource request node, the present exemplary embodiment may further obtain service data of the resource request node, and in an exemplary embodiment, the feedback information may further include a service data obtaining request for the resource request node;
when credit investigation data of the resource request node is provided according to the credit investigation acquisition request, service data of the resource request node can be provided according to the service data acquisition request, so that the target resource providing node judges whether the resource request is approved or not according to the credit investigation data and the service data.
In this exemplary embodiment, the target resource providing node may perform auditing according to credit investigation data of the resource requesting node to determine whether to establish a resource request protocol with the target resource providing node, and may also perform judgment according to service data of the resource requesting node. The business data may be operation data capable of reflecting the business status of the resource request node, for example, when the financing transaction demand party is an enterprise, a financial statement, investment income, cash flow, operation status, and the ability to undertake debt of the enterprise may all be used as the business data. The target resource providing node may perform auditing on credit investigation data or service data of the resource requesting node, or may perform auditing in combination with the credit investigation data and the service data to determine an auditing result, specifically, a first score may be obtained according to the credit investigation data of the resource requesting node, a second score may be obtained according to the service data, and the auditing result is determined by integrating the first score and the second score, and in addition, different weights may be set for the first score and the second score according to the importance of the credit investigation data and the service data to determine a more accurate auditing result.
In an exemplary embodiment, in establishing a resource request protocol with a target resource providing node, the resource request protocol is signed with an electronic signature of the resource requesting node in the blockchain.
in general, when a resource request protocol is established by a target resource providing node, a text contract about the protocol is generated by the resource request node, and in the present exemplary embodiment, the resource request protocol may be written into a block chain, and a signing request is initiated to each node in the block chain based on a pre-configured intelligent contract in the block chain, and the resource request node signs the resource request protocol by using an electronic signature, so that the resource request protocol has real effectiveness. The resource request agreement can be signed by part or all of the nodes in the block chain to take effect to indicate the approval of each node for the resource request agreement, and the signed resource request agreement is written into the block in the block chain.
In addition, if the resource requesting node or other nodes do not agree on the resource request agreement, the signing request can be unresponsive, i.e., no signing confirmation for the resource request agreement is returned, or signing denial feedback for the target contract is returned. If the blockchain does not receive the signing confirmation for the resource request protocol submitted by the resource request protocol signing participant in the preset time length or receives the signing rejection feedback for the resource request protocol submitted by at least one signing participant, the resource request protocol can be regarded as an invalid state, and the target resource providing node cannot establish the resource application relationship with the resource request node.
In order to ensure the security and transparency of the resource application process, in an exemplary embodiment, the block chain further includes a public square node; after the resource request protocol is established and signed, the resource application method based on the block chain may further include:
And synchronizing the resource request protocol and the signing information to the public square node, so that the public square node adds the public information to the resource request protocol.
in the exemplary embodiment, after the nodes involved in signing the resource application agreement in the blockchain complete agreement signing, the text information and signing information of the resource request agreement may be written into the blocks of the blockchain. The public square node may obtain the resource request protocol and the signing information through the blockchain, which may justify the resource request protocol based on the intelligent contracts in the blockchain. For example, when the financing transaction is performed between the financing transaction funding party a and the financing transaction demand party B, after the two parties sign the financing cooperation agreement, the agreement is written into the block chain, and after the node where the justice party C is located acquires the financing cooperation agreement, the financing transaction process between the financing transaction funding party a and the financing transaction demand party B can be justiced.
in an exemplary embodiment, the resource request node may apply for joining the blockchain by:
Sending real-name authentication information to an authentication node in the block chain, and enabling the authentication node to judge whether the real-name authentication information passes the authentication;
And if the authentication node passes the real-name authentication information, adding the block chain and acquiring the electronic signature distributed by the block chain.
Fig. 3 is an interaction diagram illustrating that a resource requesting node joins a blockchain in a resource requesting method based on the blockchain in the present exemplary embodiment. The method specifically comprises the following steps: in step S311, the resource requesting node 310 sends real-name authentication information to the authentication node 320 in the block chain. The real-name authentication information may include identification information capable of reflecting the resource request node, for example, when the resource request node is an enterprise, the real-name authentication information may be enterprise business license information, enterprise legal person information, enterprise unified social credit code information, or enterprise-to-public account information, etc. After receiving the real-name authentication information sent by the resource request node, the authentication node 320 executes step S321 to process the real-name authentication information, and executes step S322 to determine whether the real-name authentication information passes authentication; if the real-name authentication information fails, a result of the failure of the real-name authentication information authentication is returned to the resource request node 310, step S312 is executed, and the result of the failure of the real-name authentication is processed, specifically, the result is analyzed, the reason of the failure of the authentication is confirmed, and the authentication is continued, or other processing is performed. If the authentication node 320 successfully authenticates the resource requesting node, it sends real-name authentication information about the resource requesting node to the blockchain 330, performs step S331, checks and processes the real-name authentication information, and performs step S332, generates an electronic signature about the resource requesting node, returns to the resource requesting node 310, and the resource requesting node 310 performs step S313 to receive the electronic signature, so as to access the blockchain through the electronic signature and establish a protocol with the target resource providing node.
It should be noted that, other nodes in the block chain, for example, nodes where each participant is located in the resource application process, such as the resource providing node, the just node, or the monitoring node, have a similar manner of adding to the block chain as the manner of adding to the block chain by the resource requesting node, and may perform real-name authentication according to the above process, obtain an electronic signature, and add to the block chain according to the electronic signature.
in an exemplary embodiment, the electronic signature may be a data certificate determined by an e-commerce certificate authority.
that is, the electronic signature may be a CA (Certificate Authority) Certificate issued by a specific Certificate Authority, the blockchain may trust the accessed node by verifying the CA Certificate, for example, after the financing transaction demander obtains the CA Certificate, the node in the blockchain is accessed by the CA Certificate as a resource request node, and a resource application protocol is established with the target resource providing node based on the CA Certificate, and the like. The CA certificate can be used as the unique identity information of each participant access block chain in the resource application process, each node in the block chain can be effectively managed by setting the CA certificate, and the reliability of each node in the block chain can be increased.
An exemplary embodiment of the present disclosure also provides a resource request device based on a block chain. Referring to fig. 4, the apparatus 400 may include a request issuing module 410 configured to issue a resource request in a blockchain, so that a target resource providing node of at least one resource providing node sends feedback information in response to the resource request; the protocol establishing module 420 is configured to establish, in response to receiving the feedback information, a resource request protocol with the target resource providing node through an intelligent contract preconfigured in the block chain; the resource obtaining module 430 is configured to obtain the resource provided by the target resource providing node through the resource request protocol.
in an exemplary embodiment, the feedback information includes a credit acquisition request for the resource request node; the protocol establishment module may include: the credit investigation data providing unit is used for responding to the received feedback information, providing credit investigation data of the resource request node according to the credit investigation acquisition request and enabling the target resource providing node to judge whether the resource request is approved or not according to the credit investigation data; and the protocol establishing unit is used for responding to the received information that the audit is passed and establishing a resource request protocol with the target resource providing node through an intelligent contract configured in advance on the block chain.
