2. Next, a scheme for cross-border matching based on blockchains is introduced.

1. First, the steps of efficient registration are described.

In one embodiment, the cross-border matching processing method based on the blockchain may further include:

the enterprise node initiates a registration application and sends the registration application to the blockchain network;

The financial institution node receives a registration request sent by the blockchain network, initiates a registration consensus request according to the registration request, and sends the registration consensus request to the blockchain network;

each cross-border matching processing participant node receives a registration consensus request sent by the blockchain network, performs registration consensus processing according to the registration consensus request, and sends a registration consensus result to the blockchain network;

the financial institution node receives all registration consensus results sent by the blockchain network, and sends a registration passing message to the blockchain network when the passing proportion of all registration consensus results exceeds a preset value;

the enterprise node receives the registration pass message sent through the blockchain network and displays the registration pass message to the user.

In specific implementation, the scheme for registering is efficient and convenient, and the cost is saved.

the financial institution node receives all registration consensus results sent by the blockchain network, adds the enterprise into a blacklist when the proportion of the registration consensus results passing through is smaller than a preset value, and sends a message that the registration fails to pass through to the blockchain network;

The enterprise node receives the registration failed message sent through the blockchain network and displays the registration failed message to the user.

In specific implementation, the scheme of registration prevents credit problems such as fraud and the like and ensures the safety and efficiency of cross-border matching.

In implementation, as shown in fig. 3, an enterprise client initiates autonomous registration, and applies for authentication to become a platform user. When the enterprise client applies for the platform to become the platform authentication user, the bank asks the client to submit the basic information of the enterprise, the legal information and the operation information, the bank system establishes a block chain for registering the enterprise user, the bank and the third party organization, the government and the platform stock enterprise user, the system initiates application consensus actions among the autonomous registration application authentication enterprise user, the bank, the third party organization, the government and the platform accumulation enterprise user, then judges whether the consensus is approved, if the consensus is approved, the client is informed of the approval of the application, and the platform authentication user is formed, the enterprise information of the user and the information are recorded into the distributed account book. If the consensus action is refused, notifying the client that the application is refused, adding a blacklist, and if the client wants to be a platform authentication user, requesting offline contact with a platform staff for identity authentication.

If the verification and identification are carried out, the enterprise user information is recorded to a blacklist, and the information is not allowed to be issued.

3. Next, a scheme for ensuring the safe and reliable supply-demand butt joint and thus ensuring the safety of cross-border transactions is introduced.

In addition to the steps 101-105, in one embodiment, the cross-border matching processing method based on the blockchain may further include:

the financial institution node receives all the supply-demand butt joint consensus results sent by the block chain network, and sends a supply-demand butt joint disallowing release message to the block chain network when the passing proportion of all the supply-demand butt joint consensus results is smaller than a preset value;

the originating enterprise side node receives the information that the supply and demand docking is not allowed to be published and sends the information that the supply and demand docking is not allowed to be published to the user.

In specific implementation, as shown in fig. 5, an enterprise user issues a demand for supply-demand docking on a platform, and the platform sends consensus actions to banks, third party institutions, governments and enterprises similar to, related to or cooperated with the enterprise through a distributed account book, and if the user is not in a blacklist, the verification is passed, and then the demand-supply docking information is issued successfully without manual auditing. If the verification and identification are performed, the enterprise user information is recorded to a blacklist, and the supply and demand docking information is not allowed to be issued.

4. Next, a scheme is introduced to ensure the security of the intentional information of the collaboration, thereby ensuring the security of the cross-border transaction.

The related enterprise side nodes receive supply and demand docking information sent by a block chain network; receiving intention information (equivalent to information for confirming cooperation) input by a user according to supply and demand docking information, and sending the intention information to a blockchain network;

the financial institution node receives the intention information sent by the blockchain network, and sends the intention information to the blockchain network when the enterprise node sending the intention information is determined to be the enterprise node achieving the intention of the collaboration;

the method comprises the steps that an initiating enterprise side node receives intention information sent through a blockchain network and displays the intention information to a user; receiving the intentional information input by the user according to the determination of the intentional information input; transmitting the determined achievement designation information to the blockchain network;

the financial institution node and the enterprise party node achieving the intentional cooperation receive the determined intentional cooperation information sent by the blockchain network, perform intentional cooperation processing according to the determined intentional cooperation information, and send the intentional cooperation processing result to the blockchain network;

the node of the initiating enterprise receives the intentional consensus processing result sent by the blockchain network, and when the intentional consensus processing result passes, the node issues intentional information to the blockchain network.

In the specific implementation, the implementation mode for ensuring the safety and reliability of the intentional information of the collaboration further improves the safety and efficiency of cross-border transaction processing.

In specific implementation, as shown in fig. 6, when an enterprise user issues cross-border matching to achieve an intentional result of collaboration on a platform, the platform sends an consensus action to a bank through a distributed account book to achieve the intentional result of collaboration with the enterprise, verification is passed, and if the user is not in a blacklist, the intentional result of collaboration information is successfully issued without manual verification. If the verification and identification are carried out, the enterprise user information is recorded to a blacklist, and the purpose that the intentional information is not allowed to be issued is achieved.

5. Next, a scheme is introduced for guaranteeing the security of providing financial services, thereby guaranteeing the security of cross-border transactions.

the enterprise node which initiates the enterprise node or achieves the intentional intention receives the financial service application input by the user, and sends the financial service application to the blockchain network;

the financial institution node receives a financial service application sent through the blockchain network, initiates a financial service application consensus request according to the financial service application, and sends the financial service application consensus request to the blockchain network;

The financial institution node, the initiating enterprise node and the enterprise node achieving the intention of the collaboration receive a financial service application consensus request sent through the blockchain network, perform financial service application consensus processing, and send a financial service application consensus processing result to the blockchain network;

the financial institution node receives a financial service application consensus processing result sent by the blockchain network, and sends a notification message for approving the financial service application to the blockchain network when the consensus processing result is judged to pass;

the method comprises the steps that an initiating enterprise node or an enterprise node achieving an intentional intention receives a notification message which is sent through a blockchain network and approves a financial service application; the notification message approving the financial service application provides a basis for financial services for the financial institution node.

In specific implementation, the scheme for guaranteeing the security of the financial service further improves the security and efficiency of cross-border transactions.

In specific implementation, as shown in fig. 7, the bank provides the financial service according to the distributed ledger enterprise intention authentication information, and facilitates the intention to land.

6. Next, a scheme is introduced to record the negotiation result application, thereby ensuring the security of the cross-border transaction.

the financial institution node, the enterprise party node of the negotiating parties and the third party institution node receive the tetragonal consensus request sent by the blockchain network, perform consensus processing, and send the consensus processing result to the blockchain network;

the financial institution node receives the consensus processing result sent by the block chain network and displays the consensus processing result to the user; a negotiation result entered by the user is received.

In specific implementation, the implementation of the record negotiation result application further improves the security and efficiency of cross-border transactions.

In specific implementation, as shown in fig. 8, a bank staff records a negotiation result application, a bank initiates fingerprint or face recognition consensus actions to enterprises of both sides, the enterprises of both sides input the fingerprint or perform face recognition, the bank verifies client identity information such as the fingerprint and the face through a distributed account book, judges whether the identity information of the enterprises of both sides passes verification, the query result is that a cardholder belongs to a blacklist, and informs the bank staff that the record negotiation result is refused. If the identity information of the enterprises passes verification, a consensus action is initiated at the bank, the enterprises of the two parties and the third party, if the identity information passes verification, a negotiation result is recorded, otherwise, the bank staff is refused to record the negotiation result application.

For ease of understanding, the following description will generally be given with reference to fig. 9.
