All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For the cross-regional service, the network point configured with the service needs to store the transaction data of the service, and when the transaction data of the service is stored, a corresponding data storage system needs to store the data, so that the data stored in the data storage system can be checked and modified only by a user with authority, the possibility of tampering the data is high, and the safety and reliability of the data storage are low. And the data of each website is stored independently, so that each system needs to be managed by a special person, more manpower and material resources are wasted, and a unified management mechanism is lacked.
In order to solve the technical problem, the inventor finds that the blockchain has a tamper-proof function, if transaction data is directly stored in the blockchain, the blockchain can be prevented from being tampered, in addition, data of all network points are stored in the blockchain, the problem that the data storage system is independently built by all network points to waste manpower and financial resources is avoided, and unified management of the data is realized.
Specifically, the invention provides a blockchain-based information processing method, a blockchain-based information processing device and a blockchain-based data management system, which are mainly applied to a cross-regional business scenario such as cross-border money transfer and transfer. Taking cross-border money transfer as an example, bank cross-border money transfer is an important public service, and becomes one of important support posts for international bank development, and along with the expansion of the service lines of banks and the continuous increase of overseas banks, how to ensure the safety, reality, legality and convenience of the cross-border money transfer becomes an important proposition. Considering the complexity of the current bank management and lacking a unified reconciliation mechanism, the invention provides a mode of carrying out the corresponding part of the line endorsement based on the line endorsement and the business requirement, and creatively builds an overseas remittance blockchain in the whole line range based on the alliance chain Fabric, so that the line has the permission of admittance, the traceability and the non-falsifiability of the transaction are ensured, the manpower reconciliation cost is reduced, and the comprehensive management level of the bank is further improved.
It should be noted that the information processing method, device and data management system based on blockchain provided by the invention can be used in the blockchain field or the financial field. The foregoing is merely exemplary, and the application fields of the information processing method, the information processing device and the data management system based on the blockchain provided by the invention are not limited.
Specifically, in the embodiment of the present invention, the data management system includes a plurality of server clusters, different server clusters in the data management system use different channels, and servers located in the same server cluster share the same channel; the server with the endorsement function in the server cluster is used as an endorsement node, and the server with the submitting function is used as a submitting node. Through the data management system, the endorsement node in the server cluster can acquire the transaction information sent by the client to the target channel, signature operation is carried out on the transaction information to obtain target transaction information, the target transaction information is sent to the client so that the client can send the target transaction information to the sequencing server, the sequencing server generates a transaction block corresponding to the target transaction information and sends the transaction block to the target channel, and the submitting node in the target server cluster can store the transaction block into a block chain corresponding to the target server cluster. The transaction data is stored in the blockchain, and the blockchain has the characteristic of non-tampering, so that the possibility of tampering the transaction data on the blockchain is reduced, and the safety and reliability of data storage are improved. Furthermore, each website is not required to be configured with a corresponding data storage system, and the data storage system is uniformly stored by adopting a block chain, so that the safety and reliability of data storage are improved, and the management is convenient.
Based on the above, the embodiment of the invention provides an information processing method based on a blockchain, which is applied to an endorsement node in a target server cluster, wherein the target server cluster is any server cluster in a data management system. The architecture of the data management system will now be described.
The data management system comprises a plurality of server clusters, in this embodiment referred to as Fabric-CA server clusters. Each server cluster is composed of a plurality of nodes, and in order to avoid the problem of single point of failure caused by the arrangement of a plurality of nodes on one server, in this embodiment, each node is arranged on a different server, that is, each server is used as a node. That is, each server cluster is made up of multiple servers.
For each server cluster, in the cluster, a server with an endorsement function is used as an endorsement node (Endorsing Peer), and a server with a commit function is used as a commit node (Committing Peer).
Specifically, taking a banking system as an example, in general, the banking system is provided with a headquarter and branches corresponding to the headquarter in a plurality of countries or regions.
In this embodiment, the endorsement node is generally the above-mentioned server and headquarter server set in the headquarter of different countries or regions, and the submitting node may be the above-mentioned endorsement node or may be a branch server with submitting authority.
Different server clusters in the data management system use different channels for different server clusters, and servers in the same server cluster share the same channel.
Referring to fig. 1, in this embodiment, a full-line-scope alliance chain blockchain system is built based on super ledger Fabric, so that the line has permission for admission, traceability and non-falsification of transactions are ensured, manpower account checking cost is reduced, and comprehensive treatment level of banks is further improved.
The Fabric formal version adopts a Kafka consensus mechanism at present, and compared with the PBFT of version 0.6, the throughput rate of transactions can be greatly improved, and thousands of transactions per second can be achieved.
Since the Fabric native built-in level db database builds on top of the application container engine dock, internal data would be lost if the container is closed, a disaster that is not imaginable to the bank, so the persistent command is used to backup the data to the local machine when the container is created.
Two channel forms are provided, namely a primary channel and a secondary channel 1-N.
Primary channel:
the server of the global headquarter of the present line is added into a first-level channel which is mainly responsible for checking, auditing and counting the cross-border business development conditions of each country and region, and the abnormal transaction is checked, and endorsement nodes are designated as the global headquarter.
A secondary channel:
servers of the website institutions in the same country or region should join the same channel, the channel name is named by the country, and the endorsement node is designated as the headquarter of the country and region.
The above division is used because:
on the one hand, because the blockchain belongs to the P2P network, if the space interval between the nodes is larger, the network delay is influenced, and the network throughput is further reduced, so that the mechanisms with relatively close geographic positions are placed in the same channel. And on the other hand, the cross-border remittance counter party information is convenient to comb, and data remittance to the same country and region are logically aggregated together, so that the range of the data is reduced.
In practical application, each channel is provided with a corresponding Head and branch, and for the primary channel, it is provided with a Head1, a branch1, etc., where the Head1 may be a server of a headquarter, and the branch1 may be a server of each headquarter.
For the secondary channel, it is provided with a Head2.1 … Head2.N, branch3, etc., and Head2.1 … Head2.N may be a server of a headquarter. branch3 may be a server for each row.
Note that a branch in a primary channel may be referred to as a Head in a secondary channel. In addition, the number in each channel can be set according to actual requirements.
The Head in each channel may be used as an endorsement node as described above, and the endorsement node may also be used as a commit node. The branch in the secondary channel described above may be used as a commit node. The greater the number of nodes, the stronger the non-tamper evident of the ledger.
In this embodiment, the servers of the headquarter and the headquarter are used as management servers, so that the management of cluster members is realized, and other members want to join the overseas remittance blockchain and have signatures of the headquarter or the headquarter organization.
In practical applications, a blockchain system is provided for the data management system, where the blockchain system includes the same number of blockchains as channels, and each channel corresponds to a blockchain. Servers within the same channel may access the corresponding blockchain. In this embodiment, the servers of the headquarter and the headquarter, or the servers of the headquarter and the branch respectively maintain a totally identical ledger, and any party cannot tamper with the transaction.
Based on the above, the embodiment of the invention provides an information processing method based on a blockchain, which is applied to an endorsement node in a target server cluster, wherein the target server cluster is any one server cluster in a data management system, and a channel corresponding to the target server cluster is called a target channel.
Referring to fig. 2, the blockchain-based information processing method may include:
s11, acquiring transaction information sent to a target channel by the client.
The target channel is a channel corresponding to the target server cluster.
In this embodiment, other servers in the channels of each website than the above may be used as clients, for example, a first server in website a is added to the channels, and a second server is used as a client.
For a website, a plurality of cross-regional services, such as receiving a plurality of cross-border remittance services, can be received, in order to save processing times, transaction data of the plurality of services can be combined and submitted to a target channel of an area where the website is located as integral transaction data, namely, a proposal, and a target server cluster corresponding to the target channel signs the proposal and subsequently stores the proposal into a blockchain.
In practical applications, there are a variety of types of information that is sent into the channel, such as transaction information that needs to be signed, and information that needs to be added to the blockchain. In this embodiment, the endorsement node needs to acquire information in the target channel, and screen transaction information that needs to perform signature operation from the acquired information.
S12, signing operation is carried out on the transaction information, and target transaction information is obtained.
In this embodiment, the endorsement node performs verification operation on the transaction information first, and performs signature operation on the transaction information to obtain target transaction information when verification passes.
And S13, sending the target transaction information to the client so that the client sends the target transaction information to a sequencing server, and the sequencing server generates a transaction block corresponding to the target transaction information and sends the transaction block to the target channel so that a submitting node in the target server cluster stores the transaction block into a block chain corresponding to the target server cluster.
Specifically, after the endorsement node sends the target transaction information to the client, the client verifies the signature, after the verification is passed, the client sends the target transaction information to a sequencing server, the sequencing server generates a transaction block corresponding to the target transaction information, and sends the transaction block to the target channel, and for the submitting node in the target server cluster in the target channel, the transaction block is stored in a block chain corresponding to the target server cluster.
The above-mentioned order server is not a server in the target server cluster, but other servers outside the cluster, like the client.
It should be noted that, in this embodiment, both the endorsement node and the submitting node processing processes need to perform verification operations, and the verification process only needs to use a conventional verification process.
In addition, taking cross-border remittance as an example, the blockchain in the invention can be used for expanding the intelligent contracts added with the cross-border remittance function in the later period. The cross-border money transfer module of the original overseas bank core system is migrated to a blockchain background Fabric server, information of a payee, a sender, an amount, a currency, a country and the like which are input by a client foreground are processed by using the background server, and a debit and credit account is updated after successful money transfer. The method realizes the direct processing of background logic on the chain, reduces the development quantity of the core module and provides service diversity.
In addition, the signature is performed only by using the endorsement node, and the signature of any branch in the endorsement node and the same channel may be used to consider that the signature is successful in order to improve the security. Namely:
AND(‘head’,OR(‘branch1’,’branch2’,’…’,’branchN’))
this policy indicates that endorsements were successful by applying a signature to the head and applying a signature to any of branch1, branch2, …, and branch n.
In order that those skilled in the art can more clearly understand the specific implementation procedure of the present invention, an explanation will be made with reference to fig. 3.
In fig. 3, clients are clients, a dashed box represents a target server cluster, the target server cluster includes a head, a branch1 and a branch2, the head is set as an endorsement node, the branch1 is a submitting node, the clients send a target channel corresponding to the target server cluster, the head in the channel verifies and signs the proposal, then returns agreement proposal information (including the target transaction information), the clients receive the target transaction information, verify the signature of the information, and send the target transaction information to the orders (the ordering server) after the verification is passed. Orders order packing, generating transaction blocks, and sending the transaction blocks to the target channel, wherein branch1 adds the transaction blocks to the blockchain.
In this embodiment, the data management system includes a plurality of server clusters, different server clusters in the data management system use different channels, and servers in the same server cluster share the same channel; the server with the endorsement function in the server cluster is used as an endorsement node, and the server with the submitting function is used as a submitting node. Through the data management system, the endorsement node in the server cluster can acquire the transaction information sent by the client to the target channel, signature operation is carried out on the transaction information to obtain target transaction information, the target transaction information is sent to the client so that the client can send the target transaction information to the sequencing server, the sequencing server generates a transaction block corresponding to the target transaction information and sends the transaction block to the target channel, and the submitting node in the target server cluster can store the transaction block into a block chain corresponding to the target server cluster. The transaction data is stored in the blockchain, and the blockchain has the characteristic of non-tampering, so that the possibility of tampering the transaction data on the blockchain is reduced, and the safety and reliability of data storage are improved. Furthermore, each website is not required to be configured with a corresponding data storage system, and the data storage system is uniformly stored by adopting a block chain, so that the safety and reliability of data storage are improved, and the management is convenient.

s21, receiving a transaction data query request sent by the client.
Wherein the transaction data query request includes a transaction hash value, a transaction time, or a block height.
Because different channels can be configured with different chaincodes, the channels can be customized according to the development business requirements so as to track the tracing. The Fabric SDK provides good support for java, a transaction inquiry system based on a block chain is expanded in an overseas bank core system, a sender returns a corresponding transaction Hash value Hash every time an overseas remittance background, and the sender can submit the Hash to a bank end, namely the client end to inquire a specified transaction record. The inquiry can also be performed by matching corresponding transaction time and block height.
Specifically, the client may receive a query request from the sender, where the query request may include a transaction hash value, a transaction time, or a block height.
The client then generates a transaction data query request including a transaction hash value, a transaction time, or a block height, and sends it into the target channel.
