For example, a first may also be referred to as a second, and similarly, a second may also be referred to as a first, without departing from the scope of one or more embodiments of the application. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

First, terms related to one or more embodiments of the present application will be explained.

DoS attack: the attacks that cause DoS, which reject services, are called DoS attacks, whose purpose is to disable the normal services provided by the computer or network.

The blockchain is used as a distributed account book application, can be used for a virtual currency transaction technology, and the blockchain link points in a blockchain network face a network security problem, namely can be attacked by a network.

At present, the common solution is to set high anti-IP, and guide malicious attack flow to the high anti-IP, so as to ensure the stability and reliability of the original station; an IP white list is set, and only the IP in the white list can initiate a network request. Because of the specificity of the blockchain network, all blockchain nodes are in a public network environment, so that the public network needs to be kept in an open and connectable state, service protection cannot be carried out simply through the limitation of IP, and under the application scene of some open chains such as allied chains, the number of the blockchain nodes cannot be increased infinitely due to the limitation of a consensus algorithm, so that DOS attack cannot be resisted simply by increasing the number of the blockchain nodes.

In addition, the network environment where the block chain link points are located is complex, and operation and maintenance of the block chain nodes can be performed by different companies, different banks, different IDC machine rooms, different cloud service providers and the like, so that the network environments of the block chain networks are different, and the block chain nodes need to be individually adapted when deployed, for example, the configuration information of the block chain nodes is different when deployed under the conditions of private cloud, public cloud and mixed cloud.

Based on the method, the data processing method based on the blockchain is provided, is used for networking the blockchain in a complex network environment, can meet the safety requirement, defend common network attacks, and simultaneously enable the blockchain network to be applicable to various different network environments. The present application relates to a blockchain-based data processing system, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments.

FIG. 1 illustrates a flow chart of a blockchain-based data processing method for use in a data processing system including an authentication node, a forwarding node, and a blockchain network, wherein the blockchain network includes at least one blockchain node, the authentication node and the blockchain node being located in different networks, according to an embodiment of the present application.

With reference now to FIG. 2, FIG. 2 depicts a pictorial representation of a data processing system including an authentication node, a forwarding node, and a blockchain network in accordance with an embodiment of the present application, wherein the blockchain network includes at least one blockchain node, the authentication node and the blockchain node being located in different networks.

The verification node can be understood as a node for maintaining the security of the blockchain network, and is responsible for blocking out in the blockchain network according to a consensus mechanism.

A forwarding node may be understood as a node that protects the authentication node from network attacks and is responsible for communication between the authentication node and the blockchain network, the forwarding node does not hold traffic data in the block, but may forward the traffic data to the authentication node or blockchain node. In practical application, each verification node can be configured with a plurality of forwarding nodes, and as the number of the forwarding nodes is not limited, the malicious attack cost of illegal personnel can be increased by increasing the number of the forwarding nodes, so that the security of the verification nodes can be ensured.

A blockchain network is understood as a distributed database with a decentralization feature, and a blockchain is a string of data blocks generated by associating with each other by using a cryptography method, where each data block contains data of a primary service, and is used to verify the validity of the service data and generate a next block. The blockchain network comprises a plurality of blockchain nodes, the blockchain nodes can be understood as nodes for storing service data, and the data on each blockchain node is consistent, so that the non-falsification and reliability of the data in the blockchain network are ensured. In practical applications, the number of blockchain nodes is not limited and may depend on the number of users.

In practical application, the total amount of nodes such as blockchain nodes, forwarding nodes and the like is not limited, so that effective attacks cannot be realized for the nodes, in addition, the verification nodes can be arranged in an intranet, all traffic of the verification nodes are forwarded through the forwarding nodes, and network attacks cannot reach the verification nodes, so that the verification nodes are protected, and meanwhile, the security of the blockchain network is maintained.

Specifically, the verification node is located in an intranet, the blockchain node is located in a public network, and the forwarding node is determined to be located in the intranet or the public network according to network architecture information.

The verification node is located in an intranet environment, namely the verification node cannot directly communicate with the public network, and the verification node can communicate with the blockchain network through the forwarding node, so that the verification node cannot directly expose services to the outside or provide IP to the outside, and therefore the verification node cannot be attacked by the network.

The forwarding node can be communicated with the public network, and is directly connected with the verification node in a P2P mode to realize communication with the verification node, and can forward service data of the blockchain network to the verification node, or forward the blockinformation sent by the verification node to the blockchain network. Because the number of the forwarding nodes is not limited, effective network attack can not be performed on the forwarding nodes, so that the forwarding nodes can be exposed to the outside for service and can be exposed to the outside for IP, and the forwarding nodes can be selected to be arranged in an intranet or an extranet according to specific network architecture information. The network architecture information is a network environment, and may be a private cloud network environment, a public cloud network environment, a hybrid cloud network environment, or the like, where the forwarding node is set in an intranet or an extranet according to different network environments, for example, in the private cloud network environment, the forwarding node may be set in the intranet.

The blockchain node is arranged in a public network environment, and because the public network needs to be kept in an open and connectable state, the blockchain network can be exposed to the outside through the blockchain node, and the business operations such as adding, deleting, checking and the like can be included.

In a specific embodiment of the present application, the verification node is set in an intranet, the forwarding node and the block chain link point are set in a public network, the verification node and the forwarding node are linked through the intranet, each forwarding node can be connected through a private link, and the forwarding node and the block chain node are connected through the public network.

In practical application, the data processing system further includes a connection node, see fig. 2, where in fig. 2, the connection node is also disposed in the public network, and the connection node is used to store a list of peer-to-peer network nodes in the blockchain network, and quickly establish peer-to-peer network connection with other nodes in the network through the connection node.

Specifically, the system further comprises a connection node;

the method further comprises the steps of:

the connecting node receives an access request sent by an external node, wherein the access request is used for requesting to access the blockchain network;

determining a target block chain node in the block chain network and node information of the target block chain link point according to the access request;

And sending the node information to an external node, wherein the node information is used for enabling the external node to access the blockchain network.

The connection node may be understood as a node for establishing peer-to-peer connection between the external node and other nodes in the blockchain network, and when the newly added external node wants to join the blockchain network, the seed node needs to be connected first to establish peer-to-peer connection with other nodes in the blockchain network.

The external node may be understood as each user's own node, which becomes a blockchain node in the blockchain network after accessing the blockchain network. The access request may be understood as a request of an external node to access the blockchain network, after the connection node receives the access request sent by the external node, the connection node connects with the external node, and sends node information of the blockchain node in the blockchain network to the external node, where the node information may include node identification information of the blockchain node, such as an IP address, service data on the blockchain node, and the like, and the external node may access the blockchain network based on the node information of the blockchain node, thereby becoming the blockchain node in the blockchain network.

In practical applications, when a user wants to join in the blockchain network, an access request is sent to a connection node in the blockchain network through a server node of the user, the connection node verifies an external node according to the access request, node data about the blockchain node is sent to the external node after the verification is passed, the sent blockchain node can be any one of the blockchain nodes in the blockchain network, because the service data on each blockchain node is the same, and after the external node accesses the blockchain network, the external node can synchronize the service data on the blockchain node, thereby becoming the blockchain node in the blockchain network.

In a specific embodiment of the present application, when an external node joins a blockchain, an access request is sent to a connection node in the blockchain network along the above example, to characterize that the external node wants to join the blockchain network at this time, the connection node obtains relevant information of the external node at this time, and performs validity verification on the external node based on the relevant information, where the relevant information is information such as data structure grammar and workload verification of the external node, and after verifying that the external node is legal, node information of the blockchain node is sent to the external node.

Because the verification node is arranged in the intranet, the forwarding node, the blockchain node and the connecting node can be selected to be positioned in the intranet or the extranet according to the specific network environment, the data processing system provided by the application can be used under the conditions of private cloud, public cloud and mixed cloud by the arrangement method, and the data processing method provided by the application specifically comprises the following steps:

step 102: and the target block link point receives the service request and sends the service data carried in the service request to the forwarding node.

The target blockchain node may be understood as a blockchain node in the blockchain network, and after receiving the service request, the target blockchain node sends the service data to the verification node through the forwarding node, so that the verification node completes the block. A service request is understood to mean that a user locally assembles and issues a service, and after a block link point generates a service in a blockchain network, the service needs to be broadcasted in the blockchain network, but after the validation node validates the service, the service needs to be broadcasted in the blockchain network.

In practical application, the service request may be a transaction request of a user, the service data may be data generated by the transaction, and when the user assembles and signs a transaction locally, the service request is sent to the blockchain node, and the blockchain node sends the service data carried in the service request to the forwarding node.

In a specific embodiment of the present application, in the above example, the target blockchain node Q receives a service request, and sends service data carried in the service request to the forwarding node Z, so that the forwarding node Z sends the service data to the verification node Y.

In practical application, the number of verification nodes can be increased according to practical situations, for example, in a public network, each leader can use its own server as a verification node, each employee can be a blockchain node, each time the service data of the service request is verified by one verification node, based on the DPOS consensus mechanism, the order of the verification nodes can be a random arrangement among the servers of each leader, each time one server is selected as a verification node, and one period is then rearranged randomly and selected continuously, so that in the data processing system provided by the application, there may be a plurality of verification nodes, each verification node is configured with a plurality of forwarding nodes, and therefore, the number of forwarding nodes also has a plurality.

Specifically, the system comprises at least one verification node and at least one forwarding node, wherein each verification node has an association relationship with at least one forwarding node;

The target block link point receives a service request and sends service data carried in the service request to a forwarding node, and the method comprises the following steps:

the target block link point receives a service request and determines at least one target forwarding node according to the service request;

and sending the service data carried in the service request to the at least one target forwarding node.

The target forwarding node may be understood as forwarding nodes corresponding to the verification nodes needed for the verification, for example, 10 verification nodes are used, if the verification node 3 is used for verification in the round of the verification, the 3 forwarding nodes corresponding to the verification node 3 are the target forwarding nodes. The blockchain node sends the service data of the current service request to each target forwarding node.

In a specific embodiment of the present application, in the above example, the target blockchain node Q receives a service request, and determines 3 target forwarding nodes according to the service request: and Z1, Z2 and Z3, and sending the service data in the service request to the target forwarding nodes Z1, Z2 and Z3.

In practical application, each verification node is configured with a plurality of forwarding nodes, and the forwarding nodes are subjected to network attack because the forwarding nodes are exposed to the service, and after the forwarding nodes are subjected to network attack and the nodes are down and paralyzed, the verification nodes are also configured with other forwarding nodes, so that the verification nodes can also communicate with the blockchain network through other forwarding nodes without down.

Specifically, the system comprises at least two forwarding nodes, wherein each forwarding node has an association relationship with the verification node;

the target block link point sends the service data carried in the service request to a forwarding node, including:

in case it is determined that the first forwarding node whose operation state is a failure is included in the at least two forwarding nodes,

and the target block link point sends the service data carried in the service request to a second forwarding node with normal working state.

The first forwarding node may be understood as a node which is down due to network attack among all forwarding nodes configured by one verification node; and the second forwarding node verifies the nodes which normally operate in all forwarding nodes configured by the nodes. The target blockchain node sends the service data to the verification node through the second forwarding node which operates normally.

In a specific embodiment of the present application, in the above example, the target forwarding node Z1 is a first forwarding node that is attacked by the network and cannot normally operate, and the target forwarding nodes Z2 and Z3 are second forwarding nodes that normally operate, and then the link points of the target block send the service data to the target forwarding nodes Z2 and Z3.

Because the number of the forwarding nodes is not limited, each verifying node is configured with a plurality of forwarding nodes, when the block chain link point needs to send service data to the verifying node, the verifying node needs to be determined first, so that the forwarding node with the association relation with the verifying node can be determined, the association relation can be understood as the configuration relation between the verifying node and the forwarding node, one forwarding node can be configured to only one verifying node, and one verifying node can be configured with a plurality of forwarding nodes.

Specifically, the determining, by the target block link point, at least one target forwarding node according to the service request includes:

the target block link point determines a target verification node according to verification node information carried in the service request;

and determining at least one target forwarding node with an association relationship with the target verification node according to the target verification node.

The target verification node may be understood as a verification node required by the verification, that is, the service data of the current time may be sent to the verification node for verification, so as to generate a block. The target forwarding node may be understood as a forwarding node configured by the target authentication node. The verification node information may be understood as information of the verification node of the present round, that is, which verification node should be verified by according to the verification sequence this time, for example, the verification node information may be ID information of the verification node 3 when the verification node 3 is verified by the present round.

In practical application, the target verification node is configured with a plurality of forwarding nodes, the target blockchain node sends the service data to each target forwarding node, and each target forwarding node sends the service data to the target verification node.

In a specific embodiment of the present application, in the above example, the target block link point determines, according to the verification node information in the service request, that the target verification node is a verification node Q, and determines, according to the verification node Q, 3 target forwarding nodes Z1, Z2 and Z3 corresponding to the verification node Q, where the target forwarding node Z1 is a first forwarding node that is down, and then sends the service data to the target forwarding nodes Z2 and Z3.

Step 104: and the forwarding node receives the service data and sends the service data to the verification node.

In practical application, after the forwarding node receives the service data, the service data is forwarded to the verification node having an association relationship with the forwarding node.

In a specific embodiment of the present application, after receiving the service data, the forwarding node Z forwards the service data to the verification node corresponding to the forwarding node Z.

Specifically, the forwarding node receives the service data, and sends the service data to the verification node, including:

And the at least one target forwarding node receives the service data and sends the service data to the target verification node.

In practical application, each forwarding node sends service data to a corresponding verification node, the verification node performs de-duplication processing on the received service data, and finally the verification node only reserves one service data.

In a specific embodiment of the present application, in the above example, after receiving the service data, the target forwarding node Z2 and the target forwarding node Z3 send the service data to the corresponding target verification node Q.

Step 106: the verification node receives the service data, generates block information corresponding to the service data according to the service data, and sends the block information to the forwarding node.

The block information may be understood as block information generated by the verification node by packaging and encapsulating according to service data, where the block information includes service data, block header information, and other information of the block, and broadcasting the block information in a block chain network, so that the block can be uplink.

In practical application, since the verification node is disposed in the intranet and does not expose services to the outside, after the verification node generates the block information, the verification node sends the block information to the corresponding forwarding node, and the forwarding node sends the block information to the blockchain node in the blockchain network, and in order to reduce the communication traffic between the verification node and the forwarding node, the verification node may send the block information to the corresponding forwarding node, and the forwarding node broadcasts the block information.

In a specific embodiment of the present application, along the above example, the target verification node Q generates block information corresponding to service data according to the received service data, sends the block information to the target forwarding node Z2, and the target forwarding node Z2 broadcasts the block information to all the blockchain nodes.

In order to ensure that a forwarding node can send block information to a blockchain node and prevent the forwarding node from being down due to attack during broadcasting, a verification node can also send the block information to each corresponding forwarding node, specifically, the verification node receives service data, generates block information corresponding to the service data according to the service data, and sends the block information to the forwarding node, including:

the target verification node receives service data and generates block information corresponding to the service data according to the service data;

and sending the block information to at least one target forwarding node with an association relationship with the target verification node.

The verification node is configured with a plurality of forwarding nodes, and in order to enable the block information to be sent to the blockchain network, the verification node sends the block information to each forwarding node which normally operates.

In a specific embodiment of the present application, along the above example, the target verification node Q generates block information corresponding to service data according to the received service data, sends the block information to the target forwarding node Z2 and the target forwarding node Z3, and the target forwarding nodes Z2 and Z3 broadcast the block information to all the blockchain nodes.

Step 108: and the forwarding node receives the block information returned by the verification node and uploads the block information to a block chain network.

After the forwarding node receives the block information, the block information is uploaded to the blockchain network, so that the block information is broadcasted in the blockchain network, and the blocks on each blockchain node can be synchronized.

In one embodiment of the present application, in the above example, the target forwarding node Z2 receives the block information and sends the block information to the blockchain nodes in the blockchain network, so that the block information is completely uplink.

Specifically, the forwarding node receives the block information returned by the verification node, and uploads the block information to the blockchain network, including:

and the at least one target forwarding node receives the block information returned by the target verification node and uploads the block information to the blockchain network.

In practical application, the verification node sends the block information to each forwarding node corresponding to the verification node, and the forwarding node is placed to be attacked when uploading the block information, so that the uploading operation is terminated.

In a specific embodiment of the present application, in the above example, after the target forwarding node Z2 and the target forwarding node Z3 receive the block information, the target forwarding node Z2 is down due to attack, and the target forwarding node Z3 uploads the block information to the blockchain network, so as to ensure the normal operation of the blockchain network.

The application provides a data processing method based on a blockchain, which is applied to a data processing system, wherein the system comprises a verification node, a forwarding node and a blockchain network, the blockchain network comprises at least one blockchain node, the verification node and the blockchain node are positioned in different networks, and the method comprises the following steps: the target block link point receives a service request and sends service data carried in the service request to a forwarding node; the forwarding node receives the service data and sends the service data to a verification node; the verification node receives the service data, generates block information corresponding to the service data according to the service data, and sends the block information to the forwarding node; and the forwarding node receives the block information returned by the verification node and uploads the block information to a block chain network. The verification node is arranged in the intranet, so that the IP address of the verification node is not disclosed outwards, the communication is carried out between the forwarding node and the blockchain network, the safety of the blockchain network is guaranteed, meanwhile, the reliability of the blockchain network is improved, and the forwarding node, the blockchain node and the connecting node can be arranged in the intranet or the extranet according to the actual network environment, so that the normal operation of the blockchain network can be realized under different network environments.

The application of the blockchain-based data processing method in transaction service provided by the application is taken as an example, and the blockchain-based data processing method is further described below with reference to fig. 3. FIG. 3 is a process flow diagram of a blockchain-based data processing method for transaction traffic, the method being applied to a data processing system, the system including an authentication node, a forwarding node, and a blockchain network, wherein the blockchain network includes at least one blockchain node, the authentication node and the blockchain node being located in different networks, and the method specifically includes the steps of:

step 302: the blockchain node A receives the transaction request and sends transaction data carried in the transaction request to the forwarding node Z1 and the forwarding node Z2.

In a specific embodiment of the present application, a user a assembles and issues a transaction locally, and sends a transaction request of the transaction to a server a of the user a, namely a blockchain node a, and the blockchain node a sends transaction data carried in the transaction request to a forwarding node Z1 and a forwarding node Z2.

Step 304: the forwarding node Z1 and the forwarding node Z2 receive the transaction data and transmit the transaction data to the verification node Q.

In a specific embodiment of the present application, the forwarding node Z1 and the forwarding node Z2 send the transaction data to the blockchain node a, and the forwarding node Z1 and the forwarding node Z2 send the transaction data to the verification node Q, respectively.

Step 306: the verification node Q receives the transaction data, generates block information corresponding to the transaction data according to the transaction data, and sends the block information to the forwarding node Z1 and the forwarding node Z2.

In a specific embodiment of the present application, after receiving the transaction data sent by the forwarding node Z1 and the forwarding node Z2, the verification node Q obtains a transaction data through aggregation and deduplication of the transaction data, packages and encapsulates the transaction data only to generate a transaction block, and sends the transaction block to the forwarding node Z1 and the forwarding node Z2.
