Detailed Description
Currently, the block chain technique is widely used. Referring to fig. 1, in the prior art, a system applying the blockchain technology includes a blockchain network and various participants participating in the blockchain consensus. Referring to fig. 1, taking a participant 1 as an example, the participant 1 needs uplink data, and the participant 1 directly sends the uplink data to a blockchain node 1 corresponding to the participant 1 in a blockchain network, and the blockchain node 1 performs data uplink processing; for the data of the downlink, the block link node 1 performs the downlink processing of the data, and then directly transmits the data to the participant 1.
It can be seen that in the prior art, in the data processing implemented based on the blockchain, only the blockchain network is included, i.e. only the single-layer network is included. Both uplink and downlink processing of data for a participant needs to be performed by a blockchain node. However, with the explosion of information amount and the increase of data processing complexity, the processing capability of a single blockchain node cannot meet the requirement of data processing, and thus cannot meet the processing requirement of a blockchain participant. For example, if the participant 1 is a pay pal, the transaction data of the pay pal at the time of twenty-ten million levels is uploaded to the block link point 1 corresponding to the pay pal in real time through each service node of the pay pal in fig. 1, so that uplink data cannot be realized at all. Since the processing power of the blockchain node 1 cannot achieve the capability of processing the hundreds of millions of data in real time. As another example, party 1 needs to use the user blacklist of party 2 for transaction risk identification processing, but since the user blacklist of party 2 belongs to the private data of party 2, party 2 does not want party 1 to be able to obtain the original data of the user blacklist, and in this case, an available invisible processing is needed, which can not only allow party 1 to use the blacklist, but also cannot allow party 1 to obtain the blacklist. Whereas the prior art implementation shown in fig. 1 is limited by the processing power of the blockchain node 1 node and cannot accomplish the complex processing that is available and invisible.
In summary, in the existing data processing method for a block chain, only one block chain node corresponding to one participant performs uplink and downlink processing on data, and thus the data processing requirements of the participants cannot be met. However, if the number of the block chain link points corresponding to one participant is increased on the block chain, for example, the block chain link points correspond to the pay bank, because the data size is large and the processing is complex, a plurality of block chain nodes corresponding to the pay bank are arranged on the block chain to process the data, in this way, the data are difficult to be accepted by other participants who participate in the block chain consensus, the service requirements of the other participants are not met, and the existing block chain system architecture needs to be modified.
Therefore, it is considered that a secondary network including a plurality of nodes is added between the blockchain network and the participants, the blockchain network is used as a primary network to transfer data, the secondary network is responsible for uplink and downlink processing of data corresponding to the participants, and the dual-layer network operates cooperatively, so that various more complex processing of the corresponding participants can be completed based on the secondary network, and the data processing capability is improved. In addition, the method does not need to change the existing block chain system architecture, meets the requirements of all participants who participate in block chain consensus, and is easy to realize.
Specific implementations of the above concepts are described below.
Firstly, a novel data processing system architecture based on a block chain is designed. As shown in fig. 2, the system includes: the secondary network consists of a block chain link point and at least one intermediate node, and the block chain link point belongs to one node in the block chain network.
Referring to fig. 2 and 3, the secondary network is connected to the blockchain network and a corresponding one of the participants of the secondary network, respectively. Each blockchain node corresponding to each participant is included in the blockchain network. In the network application architecture shown in fig. 3 described above, a secondary network is set only for party 1 and party 4, and no secondary network is set for party 2 and party 3. It is to be understood that the number of secondary networks shown in fig. 3 is merely illustrative and not limiting. A secondary network may be set between the blockchain network and a participant according to actual service needs. For example, when the processing capacity of the blockchain node corresponding to one participant cannot meet the requirement, a secondary network may be set for the participant, or certainly, a secondary network may be directly set for all the participants without considering the processing capacity of the blockchain node.
The secondary network is described in detail below with reference to fig. 2 and 3:
each secondary network includes at least one intermediate node (for example, as shown in fig. 2 and 3, the secondary network 1 includes 3 intermediate nodes) and one blockchain node (for example, as shown in fig. 2 and 3, the blockchain node 1) located in the blockchain network, and all nodes in the secondary network collectively complete data processing of corresponding participants. It can be seen that data processing originally required to be performed by one blockchain node is distributed to all nodes in the secondary network to be performed together, so that the data processing capability is improved, and the data concurrency requirement and the more complex processing requirement can be met based on a plurality of nodes in the secondary network.
The secondary network may be local to the parties connected thereto, and may be established using a local area network. For example, the blockchain node 1 and the intermediate nodes form a secondary network 1 through the local area network of the participant 1. In this case, the block link points and intermediate nodes in the secondary network are located on the participating side.
Certainly, the secondary network can also be located at the cloud end and constructed by utilizing a public network. In this case, for example, in the secondary network 1, at least one of the blockchain node 1 and each intermediate node is located in the cloud, for example, the blockchain node 1 is located in the cloud, and each intermediate node in the secondary network is located in the local of the participant 1, or any intermediate node in the secondary network is located in the cloud, and other intermediate nodes and blockchain nodes 1 are located in the local of the participant 1, and so on. At the moment, the block chain nodes and the intermediate nodes form a secondary network through the public network.
In the secondary network, the number of intermediate nodes may be set by at least one of the following ways:
the method I is set according to actual business requirements.
For example, for a participant with huge traffic or very complex data processing, the number of intermediate nodes in the secondary network corresponding to the participant can be set to be larger, so that the data processing is completed by more nodes in the secondary network.
And the second mode is set according to the organizational structure of the participants.
For example, if the participating party includes a transaction processing department, a fund transfer department, a security control department, etc., an intermediate node may be set in the secondary network for each department, for example, referring to fig. 4, the intermediate node 1 in the secondary network 1 corresponds to the transaction processing department, and the service nodes of the transaction processing department in the participating party are all connected to the intermediate node 1; the intermediate node 2 in the secondary network 1 corresponds to a fund transfer department, and service nodes of the fund transfer departments in the participants are connected to the intermediate node 2; the intermediate node 3 in the secondary network 1 corresponds to a security control department, and service nodes of the security control departments in the participants are all connected to the intermediate node 3. The system structure shown in fig. 4 can set an intermediate node in the secondary network for each department of the participant, so that the participant can be better provided with services for each department.
The system architecture shown in fig. 3 and 4 includes two layers of networks, namely, a blockchain network and a secondary network between the blockchain network and the participants. In one embodiment of the present specification, more levels of networks may also be provided between the secondary network and the participants according to the needs of the actual service. For example, referring to fig. 4 and 5, if the data volume of the security management and control department is too large and the data is complex, and one intermediate node 3 in the secondary network cannot meet the data processing requirement, for example, cannot receive massive data concurrent with the service nodes of the security management and control department in real time, a tertiary network may be set between the intermediate node 3 and each service node of the security management and control department, and it can be understood that the network may also include a tertiary network, a quaternary network, or even a higher-level network. The principle of setting may be: an intermediate node may be used to build a lower level network as long as its processing power cannot meet the data processing requirements of the intermediate node.
In an embodiment of the present specification, a data processing method based on a blockchain is provided, which is applied to a blockchain node. As mentioned before, the block link point belongs to a node in the block chain network, and the block link point and at least one intermediate node constitute a secondary network through which a participant is connected to the block chain network. Referring to fig. 2 to 6, the method includes:
step 601: the block chain node receives first data sent by a block chain network; the receiving party of the first data is the participating party corresponding to the block link point.
Step 603: the block link node shares the received first data to the secondary network, so that the first data are processed in the secondary network and the obtained first processing result is sent to the participant.
Step 605: the blockchain node receives second data sent by the participant into the secondary network.
Step 607: and the block chain link point uploads a second processing result obtained after processing the second data in the secondary network to the block chain network.
In one embodiment of the present disclosure, in step 603, the processing the first data in the secondary network includes: the first data is used by at least one intermediate node in the secondary network for data checking and/or calculation.
In one embodiment of the present specification, in step 607, the second data is processed in the secondary network, including: the data is checked and/or calculated by at least one intermediate node in the secondary network using the second data.
The embodiment of the present specification further provides a data processing method based on a block chain, which is applied to an intermediate node. As mentioned before, the intermediate node is located in a secondary network comprising the intermediate node and a blockchain node, through which a participant is connected to the blockchain network. Referring to fig. 7, the method includes:
step 701: the intermediate node receives first data shared by the block chain nodes in the secondary network, processes the first data, and sends a first processing result obtained by the processing to the participants through the secondary network.
Step 703: and the intermediate node receives second data sent to the secondary network by the participant, processes the second data, and uploads a second processing result obtained by the processing to the block chain network through the block chain link point in the secondary network.
In step 701, the processing the first data includes: the intermediate node performs a checksum and/or calculation of the data using at least a portion of the first data. In step 703, processing the second data includes: the intermediate node performs a checksum/calculation of the data using at least a portion of the second data.
As can be seen from the above-mentioned flows shown in fig. 6 and 7, when data sent to a participant is linked down, each node in the secondary network may process the data of the link down, so that the data may be processed more complicatedly based on the processing capacity of all nodes in the secondary network. For example, referring to fig. 3, a participant 1 needs to use a user blacklist of a participant 2 to perform a transaction risk identification process, but because the user blacklist of the participant 2 belongs to private data of the participant 2, the participant 2 does not want the participant 1 to obtain original data of the user blacklist, at this time, based on the secondary network provided in this specification, original data of the user blacklist sent by the participant 2 from a blockchain network may be encrypted and stored in the secondary network, and at the same time, the secondary network receives the encrypted user list sent by the participant 1, which needs to perform a transaction risk identification, any one or more nodes (such as all intermediate nodes) in the secondary network identify a user at risk in the participant 1 by comparing the user blacklist stored in the secondary network with the user list sent by the participant 1, and then the judgment result, namely the information of the users with risks in the user list of the participant 1 is sent to the participant 1. Therefore, the processing of obtaining the original user blacklist and the processing of judging the users with risks according to the blacklist are both carried out in the secondary network without being issued to the participant 1 for execution, and the effect of being available and invisible to the user blacklist is achieved for the participant 1.
As can be seen from the above-mentioned processes shown in fig. 6 and 7, when a participant uplink data, each node in the secondary network can process the data to be uplink, so that the uplink data can be processed more complicatedly based on the processing capability of all nodes in the secondary network. For example, the participant 1 is a pay pal, where billions of data of a level are generated at twenty-one hours and need to be uploaded to the blockchain network, at this time, the participant 1 may send the billions of data to the secondary network, each node in the secondary network stores the data, and distributes uplink processing of the data, for example, different nodes in the secondary network encrypt and decrypt different data, and the like. Because the uplink processing is distributed over multiple nodes in the secondary network, rather than just one blockchain node, the requirement for data concurrency is met.
When the secondary network is directly connected to the participant, that is, there is no next network between the secondary network and the participant, in step 701, any one or more nodes in the secondary network may send the first processing result to the participant. In step 703, the second data sent by the participant may be received by any one or more nodes in the secondary network and shared into the secondary network, so as to process the second data in the secondary network.
When a next-level network is formed by using an intermediate node in a second-level network and at least one lower-level intermediate node, such as the three-level network shown in fig. 5, in step 701, the intermediate node in the second-level network transmits a first processing result obtained by processing to the next-level network, so as to trigger each intermediate node in the next-level network to perform predetermined processing (such as decryption or other set processing) on the first processing result and then send the first processing result to the participant; in step 703, the second data is first sent to a next-level network, such as the third-level network shown in fig. 5, by the participant, and is sent to an intermediate node in the secondary network after being processed by the next-level network (e.g., encrypted or otherwise configured), where the intermediate node shares the received second data with the secondary network to process the second data in the secondary network (e.g., related processing of data uplink, etc.).
Referring to fig. 4, an intermediate node may correspond to a set department within a participant and communicate with a service node of the set department.
In an embodiment of the present disclosure, the blockchain network requires consensus, and the secondary network does not require consensus, so that the blockchain network and the secondary network are separated from each other, which can ensure the efficiency of consensus in the blockchain network, and the blockchain network and the secondary network are not limited by whether they are the same cloud.
In an embodiment of the present specification, a data processing apparatus based on a blockchain is further provided, where the blockchain node is a node in a blockchain network, and the blockchain node and at least one intermediate node form a secondary network through which a participant is connected to the blockchain network. Referring to fig. 8, the apparatus 800 includes:
a blockchain consensus processing module 801 configured to receive first data sent through a blockchain network; uploading the obtained second processing result to a block chain network;
a data downlink processing module 802, configured to share the received first data in the secondary network, so as to process the first data in the secondary network and send the obtained first processing result to the participant;
the data uplink processing module 803 is configured to receive second data sent by the participant to the secondary network, and obtain a second processing result obtained after the second data is processed in the secondary network.
In another embodiment of the present specification, a data processing apparatus based on a blockchain is further provided, where the data processing apparatus is applied to an intermediate node, the intermediate node is located in a secondary network, the secondary network includes the intermediate node and a blockchain node, and a participant is connected to the blockchain network through the secondary network; referring to fig. 9, the apparatus 900 includes:
