The system architecture of each settlement account in the blockchain network includes a business server 34, a certificate server 35 and an ledger server 36.
In another optional implementation manner of this embodiment, the settlement account may send settlement account information to a server corresponding to the central node through a bound terminal, so as to upload the settlement account information by calling a blockchain interaction interface through the server. And a block chain interactive interface can be called through a server corresponding to the central node to distribute the identity certificate to the settlement account, the settlement account is added into the block chain network, and then the settlement account directly calls the block chain interactive interface to upload settlement account information by self.
Fig. 2 is a flowchart of uploading settlement account information by calling a blockchain according to an embodiment of the present invention, and as shown in fig. 2, in this embodiment, a process of uploading settlement account information by calling a blockchain interaction interface by a server includes:
and step S210, generating an information change proposal corresponding to each settlement account according to the settlement account information.
Specifically, after receiving the settlement account information, the server uploads each piece of the settlement account information to a blockchain network through the blockchain interaction interface, so that a service server in the blockchain network architecture through a center node corresponding to the server identifies instruction information included in the settlement account information, and generates a corresponding information change proposal according to the instruction information and content in the settlement account information. The explanation will be given by taking the settlement account information as information transmitted from a terminal bound to the trading market agent. The settlement account information includes instruction information, account information, and relationship information. The instruction information may be update account information, the account information may be account information to be updated, and the relationship information may include account information of settlement accounts of the market trading subject counter-party and the trading intermediate party. And after identifying that the instruction information is updated account information, the server generates an information change proposal comprising the account information and the relationship information.
In an optional implementation manner of this embodiment, the content of the information change proposal generated by the server may be shown in table 1:
TABLE 1
In another optional implementation manner of this embodiment, after the settlement account joins the blockchain network by distributing a certificate through a server and directly calls a blockchain interaction interface to upload settlement account information by itself, the information change proposal is generated by a service server corresponding to the settlement account in the blockchain network.
Step S220, the information change proposal is sent to an endorsement node of the block chain network.
Specifically, after generating an information change proposal, the server sends the information change proposal to each endorsement node in the blockchain network.
In another optional implementation manner of this embodiment, when the information change proposal is generated by a service server corresponding to the settlement account in a blockchain network, the information change proposal is sent to each endorsement node in the blockchain network through the service server corresponding to the settlement account in the blockchain network.
Step S230, receiving a feedback message sent by each endorsement node based on the information change proposal.
Specifically, the endorsement nodes in the block chain network are configured to verify the validity of the received information change proposal, and when each endorsement node verifies that the information change proposal is valid, a feedback message is fed back to a sending node of the information change proposal. Wherein, the feedback message comprises an endorsement node signature used for representing the endorsement node identity. The validity verification may be to verify the accuracy of each piece of information in the information change proposal to avoid the blockchain network from performing an erroneous information change.
Step S240, generating a change file for the information change proposal according to the feedback message to update the block chain ledger of each accounting node in the block chain.
Specifically, the block chain ledger book is used for recording settlement account information of each settlement account. And when the sending node of the information change proposal is a settlement account, namely the information change proposal is generated and sent by a corresponding service server of the settlement account in the blockchain network, the corresponding service server of the settlement account in the blockchain network receives the feedback message sent by each endorsement node. And when the sending node of the information change proposal is a central node, namely the information change proposal is generated and sent by a corresponding service server of the central node in the blockchain network, the corresponding service server of the central node in the blockchain network receives the feedback message sent by each endorsement node.
In this embodiment, the generating a change file for the information change proposal according to the feedback message to update the blockchain account book of each accounting node in the blockchain further includes:
and step S241, verifying the endorsement node signature in the feedback message.
Specifically, after receiving the feedback message, the sending node of the information change proposal checks the endorsement node signature included in the feedback message, that is, determines whether the endorsement node signature is legal. A node signature table may be maintained in the service server of the sending node of the information change proposal, and the node signature table is used to record endorsement node signatures of each node in the block chain. The judging process may be, for example, detecting whether the endorsement node signature exists in the node signature table, and judging that the endorsement node signature is legal when the endorsement node signature exists; and when the endorsement node signature does not exist, judging that the endorsement node signature is illegal.
And step S242, determining the number of feedback messages with legal endorsement node signatures.
Specifically, after the endorsement node signature in the feedback message is verified, the sending node of the information change proposal records the number of the feedback messages with legal endorsement node signatures. For example, whether endorsement node signatures included in each feedback message are legal or not is detected in sequence, when the endorsement node signatures are legal, one is added on the basis of the number of the current legal feedback messages, and then the next feedback message is detected; and when the endorsement node signature is illegal, adding zero on the basis of the number of the current legal feedback messages, and then detecting the next feedback message.
And S243, in response to the number being larger than the preset threshold value, packaging the information change proposal and the endorsement node signature into a change file, and submitting the change file to a sequencing node so as to update the block chain account book of each accounting node in the block chain.
Specifically, when a sending node of the information change proposal is a settlement account, after legal feedback messages with the quantity greater than a preset threshold value are obtained, a service server of the settlement account in the block chain packages the information change proposal and endorsement node signatures into change files and submits the change files to a sequencing node so as to update a block chain account book of each accounting node in the block chain; when the sending node of the information change proposal is a transaction platform, the transaction platform is a sequencing node, and after legal feedback messages with the quantity larger than a preset threshold value are obtained, the transaction platform packages the information change proposal and endorsement node signatures into a change file at a service server in the block chain so as to update the block chain account book of each accounting node in the block chain.
In this embodiment of the present invention, the process of updating the blockchain ledger of each accounting node in the blockchain further includes:
step S244, the sorting node constructs a block according to the received modified file.
Specifically, after receiving the changed file, the sorting node sorts the received different changed files to construct a block including a plurality of changed files arranged in sequence.
Step S245, the sorting node sends the block to a submitting node to submit so as to update the block chain ledger of each accounting node in the block chain.
Specifically, after the sorting node constructs a block, the block is sent to a commit node in the blockchain network. And after receiving the block, the submitting node checks each change file in the block. The verification process may include: checking whether the information change proposal in the change file is legal, checking whether the endorsement node signature is legal, checking whether repeated endorsement node signatures exist, checking whether the change file conforms to an endorsement strategy and the like. And after the submitting node checks each change file, executing a legal change file, and updating a block chain account book of each accounting node in the block chain based on an execution result.
For example, when the information change proposal is used for updating settlement account information of settlement accounts, the submitting node replaces the existing settlement account information in the blockchain ledger by the updated settlement account information after executing the change file so as to update the blockchain ledger of each accounting node.
Fig. 4 is a schematic diagram of a blockchain network according to an embodiment of the present invention executing an information change proposal process, and as shown in fig. 4, the blockchain network includes a sending node, an endorsement node 42, a sorting node 43, and a submitting node 44 of the information change proposal. The sending node of the information change proposal comprises an application program 40 and a certificate service 41, wherein the application program 40 is used for logging in the blockchain network through the certificate service 41 and communicating with other nodes in the blockchain network.
Specifically, in the present embodiment, the identity certificate of each node is distributed by the certificate server 41 of the transaction center. The application 40 of the information change proposal sending node logs in the blockchain network through the certificate service 41 to send the information change proposal to each endorsement node 42. The endorsement node 42 feeds back a feedback message to the application program 40 after detecting that the information change proposal is legal, and the application program 40 packages the information change proposal and endorsement node signatures in the legal feedback messages into a change file and sends the change file to the sorting node 43 after acquiring the legal feedback messages of which the number is greater than a preset threshold value. The sorting node 43 sorts the received plurality of change files and constructs a block, and sends the block to the submitting node 44 after constructing the block. The commit node 44 detects the validity of each changed file in the block and executes the valid changed files to update the block chain ledger of each accounting node in the block chain.
Step S300, accessing the block chain network, and determining announcement information according to the settlement account information recorded by the block chain network.
Specifically, the server may access the blockchain network according to a preset time period, so as to determine corresponding advertisement information according to the settlement account information updated by the blockchain network within a time period. Optionally, the server may further access the blockchain network according to a preset time interval sequence or other preset time rules to determine settlement account information updated by the blockchain network from the last access to the current time to determine corresponding advertisement information. For example, when the server is a foreign exchange transaction center server, it may be set that the blockchain network is accessed once every opening day to determine the announcement information by acquiring the settlement account information recorded in the blockchain network.
In this embodiment of the present invention, the process of determining advertisement information may include:
and step S310, connecting any accounting node of the block chain network, and reading the updated settlement account information in the time period needing to be summarized.
Specifically, the server accesses the blockchain network according to a preset time period, is connected with any accounting node of the blockchain network, and reads accounting account information updated in a blockchain account book of the accounting node within a period from the last time the blockchain account book is read to the current time.
And step S320, summarizing the settlement account information to determine notice information.
Specifically, after acquiring settlement account information updated in a block chain account book in one period, the server collects the settlement account information according to a predetermined format to generate announcement information. The predetermined format may be for text, pictures, tables, etc.
Step S400, sending the announcement information to each of the terminals connected to the server.
Specifically, after determining the announcement information, the server sends the announcement information to each of the terminals connected to the server to synchronize each of the updated settlement account information. Optionally, the server is further connected to an information platform, and sends the announcement information to the information platform while sending the announcement information to each terminal, so as to publish the announcement information through the information platform, so that each terminal can query the announcement information.
In this embodiment of the present invention, after determining the advertisement information, the server further includes:
step S500, determining the counter-party settlement account of the settlement account bound by the terminal corresponding to each piece of settlement account information in the notice information.
Specifically, the server identifies content included in each piece of settlement account information in the announcement information to obtain instruction information, account information, and relationship information. For example, when the server is a foreign exchange trading center server, the terminal is a terminal for registering and binding a settlement account in the foreign exchange trading center by a trading market main body, and the trading market main body can be a bank. The instruction information in the settlement account information may be used to instruct to generate an information change proposal, for example, the account information may be updated; the account information is used for representing the basic attribute information of the settlement account, such as name, account opening row, account number, currency and the like; the relationship information is used for representing the settlement instruction information of the counter party, and may include, for example, the name, account opening row, account number, currency and other basic attribute information of the settlement account of the counter party, and the name, account opening row, account number, currency and other basic attribute information of the transaction intermediate party.
Therefore, the server can acquire the information of the settlement account of the counter party according to the relationship information included in each of the settlement account information.
Step S600, sending reminding information including the settlement account information to a terminal bound by the settlement account of the corresponding opponent according to the time information included in each settlement account information.
Specifically, the settlement account information further includes corresponding time information. The time information is generated according to a predetermined rule and the time when the updated account information becomes effective, and may be, for example, the day before the time when the account information becomes effective, the hour before the time when the account information becomes effective, or the hour after the time when the account information becomes effective. And after determining the opponent settlement accounts of the settlement accounts corresponding to the settlement account information, the server sends reminding information including the settlement account information to the terminals bound to the corresponding opponent settlement accounts at the time represented by the time information. The reminding information can be sent in forms of pop-up window, push, short message and the like so as to remind the opponent settlement account of updating the current settlement account information.
The method of the embodiment of the invention can call the block chain network to record the settlement account information sent by the terminal through the server, then acquire the settlement account information recorded by the block chain network to generate the announcement information, and then send the announcement information to each terminal connected with the server, so as to realize the calculation of the account information recorded by the block chain network, provide a uniform, high-performance and distributed settlement account database for the settlement accounts bound by each terminal, and each terminal can also inquire the settlement account information of other settlement accounts in real time through the connection of the accounting nodes in the block chain network.
