Along with the expansion of banking business and the improvement of financial systems, the types of financial products are more and more. The customer can manage money by purchasing money management products such as bonds issued by banks.

For example, the transaction initiator may send the transaction proposal to the blockchain, and the node in the blockchain calculates the transaction proposal to obtain the transaction result and records the transaction result in the master node of the blockchain.

Detailed Description
With the development of computer and cryptography technologies, the block chain technology is more and more mature and widely applied in many fields. Because the blockchain has the characteristics of decentralization, independence, safety and the like, many bank systems also adopt the blockchain technology to process part of transactions. Taking financial bonds as an example, a bank may process financial bond related transactions using federation chain technology with an admission mechanism. Therefore, the whole transaction process is public and visible, is relatively transparent, cannot be tampered with, and has high safety.
However, since the blockchain must run on a hardware device, the computational resources of the hardware device are also limited, and the blockchain also has an upper performance limit. If the requirement for computing resources for transaction processing is high or the transaction frequency is too fast, the blockchain may not be able to process transactions in time, resulting in transaction throughput reduction and failure to meet the real-time requirement of transactions.
Still taking the financial bonds as an example, the current process of processing the financial bonds through the block chain technology includes that a transaction initiator sends a transaction proposal to an endorsement node; the endorsement node calls a chain code to simulate and execute a transaction proposal; the endorsement node returns a simulation execution result to the transaction initiator; the transaction initiator submits the transaction containing the signature endorsement and the simulation execution result to the sequencing service node; the ordering service node orders the transactions to generate transaction packaging information; the sequencing service node broadcasts transaction packaging information to the main node; the main node verifies the transaction packaging information, and records the transaction packaging information to the account book after the verification is passed; the accounting node synchronizes transaction packaging information from the master node; and the accounting node informs the transaction initiator of successful transaction and the like. These steps not only require the transfer of information between the nodes in the blockchain to each other, but also consume significant computational resources. This results in a limited number of transactions that the blockchain platform can handle at the same time. When the transaction amount is too large, the real-time requirement of the transaction cannot be met.
In order to solve the problem, the present application provides a data processing method and apparatus for processing transaction information by using a data processing device under a blockchain, and the following description will describe preferred embodiments of the present application from the perspective of nodes in the blockchain. Of course, the data processing method provided by the application can be used for processing transaction data of banks and can also be used for processing other data with higher requirements on computing resources.
It should be noted that, the step related to the block chain in the embodiment of the present application may include specific steps of data uplink, asymmetric encryption, timestamp (timestamp) setting, and the like, and these specific operations are consistent with the existing block chain technology, which is not described herein again.
Referring to fig. 1, fig. 1 is a flowchart of a method of a data processing method provided in an embodiment of the present application, including:
s101: and receiving transaction proposal data sent by a transaction initiator.
When the transaction initiator needs to perform a transaction, the transaction initiator may send transaction proposal data to a node in the blockchain, so that the blockchain and the data processing device under the blockchain perform corresponding processing according to the transaction proposal data. The transaction proposal data represents the relevant information of the transaction, and can include information such as transaction type, transaction amount and the like.
In the embodiments of the present application, the blockchain may be composed of a plurality of different nodes on the chain. For example, an on-chain node may comprise an on-chain master node of an on-chain distribution node. The distribution node on the chain can be used for receiving and distributing the message, and the connection main node can be used for recording the message. Specifically, when the on-chain node includes an on-chain distribution node, the transaction initiator may send the transaction proposal data to the on-chain distribution node, so that the on-chain distribution node forwards the transaction proposal data to other nodes or devices for processing.
S102: and forwarding the transaction proposal data to a downlink data processing device.
After the transaction proposal data is obtained, the uplink node can send the transaction proposal data to the downlink data processing equipment, and the downlink data processing equipment processes the transaction proposal data to obtain transaction result information. The downlink data processing device may be a device with a data processing function, such as a computer or a server, or may be a distributed data processing device, such as a cloud computing platform or a server cluster. When the data processing equipment under the chain processes the transaction proposal data, the data such as the amount of money, interest and the like of the transaction can be calculated according to the transaction proposal data, and whether the credit level of the transaction initiator accords with the credit level required by the transaction proposal or not, whether the transaction initiator is qualified to initiate the transaction proposal or not and the like can be judged according to the identity information of the transaction initiator included in the transaction proposal data. The transaction result information obtained by the data processing equipment under the chain can comprise specific information such as income, profit and the like, and can also comprise an authentication result of the transaction initiator.
In an embodiment of the application, when the on-chain node comprises an on-chain distribution node, a dedicated off-chain channel may be established between the on-chain distribution node and the off-chain data processing device for transmitting the transaction proposal data. Specifically, when the transaction proposal data is sent to the data processing device under the link, the distribution node on the link can forward the transaction proposal data to the data processing device under the link through the dedicated channel under the link, and then the data processing device under the link processes the transaction proposal data. Further, in consideration of security of transaction data, the downlink transmission channel may use a hypertext transfer protocol over secure socket layer (https) protocol for data interaction. Since the https protocol can authenticate the sender and receiver of data, it can be ensured that the data is sent to the correct down-link data processing device. Moreover, the HTTPS protocol is constructed by a Secure Socket Layer (SSL) and a hypertext transfer protocol (http) protocol, which can prevent the transaction proposal data from being stolen and changed during the transmission process, and further ensure the security of the transaction related data.
S103: and receiving the transaction result information sent by the data processing equipment under the link, recording the transaction result information and sending the transaction result information to the transaction initiator.
After the data processing device under the link processes the transaction proposal data and obtains the transaction result information, the data processing device under the link can send the transaction result information to the node on the link. The nodes on the chain can record and store the transaction result information and send the transaction result information to the transaction initiator so as to inform the transaction initiator of the relevant information of the current transaction proposal.
In an embodiment of the present application, when the uplink node includes an uplink distribution node and an uplink master node, the downlink data processing device may send the transaction result information to the uplink distribution node. After receiving the transaction result information, the distribution node on the chain can send the transaction result information to the main node on the chain, and the main node on the chain records the transaction result information. When the distribution node on the chain receives the transaction proposal data and the corresponding transaction result information of the next transaction, a new block can be established after the main node on the chain as a new main node on the chain for recording the transaction result information of the transaction. In this way, the transaction proposal data sent by the transaction initiator can be forwarded to the data processing device under the link by the distribution node on the link, and then the transaction result information obtained by the data processing device under the link is forwarded to the host node on the link for recording and storing. In the process, the distribution node on the chain transfers and sends the transaction proposal data and the transaction result information, the main node on the chain records the transaction result information, the data processing equipment under the chain verifies and calculates the specific data of the transaction, the complex calculation process of the transaction is transferred from the chain to the chain, and only the steps with lower requirements on calculation resources, such as forwarding, recording and the like, are executed on the chain. Because the data processing equipment under the chain can be one or more equipment, theoretically, infinite computing resources can be provided, and the upper limit of the transaction quantity which can be processed by the block chain at the same time is greatly improved. Thus, even if a large number of transaction proposals are received at the same time, the blockchain can process each transaction proposal in time.
Further, considering that most of the blockchains currently processing transactions are alliance chains, only a transaction initiator passing identity authentication can view contents in the chains, and the blockchains also have a step of asymmetric encryption, in the embodiment of the present application, a distribution node on the chains can add signatures to transaction proposal data and transaction result information to improve security of transactions.
Specifically, after receiving the transaction proposal data sent by the transaction initiator, the distribution node on the chain may sign the transaction proposal data and send the signed transaction proposal data to the data processing device under the chain through the channel under the chain. The data processing device under the chain can carry out signature verification on the received transaction proposal data and judge whether the transaction proposal data comprises the signature of the distribution node on the chain. If the signature of the distribution node on the chain is detected, the transaction proposal data is not tampered, and the data processing equipment under the chain can process the transaction proposal data to obtain transaction result information and transmit the transaction result information back to the distribution node on the chain. When the distribution node on the chain sends the transaction result information to the main node on the chain, the signature can be added into the transaction result information, so that the main node on the chain records the transaction result information after the signature verification is passed. Therefore, the transaction proposal data and the transaction result information forwarded by the distribution node on the chain are signed, so that the transaction proposal data and the transaction result information can be ensured not to be falsified in the transmission process, and the security of the transaction data is further ensured.
In the embodiment of the application, a chain accounting node which is specially used for informing the transaction initiator of the transaction result information can be arranged in the blockchain. Specifically, the link node may actively acquire the transaction result information from the master node, and send the transaction result information to the transaction initiator corresponding to the transaction result information. Therefore, by setting the chain accounting node, the transaction result information can be timely notified to the transaction initiator. When the nodes on the chain include the distribution node on the chain, the master node on the chain, and the accounting node on the chain, the information interaction process between the transaction initiator, the data processing device off the chain, and the respective nodes may be as shown in fig. 2.
The embodiment provides a data processing method, wherein a link node can firstly receive transaction proposal data sent by a transaction initiator; then, the transaction proposal data is forwarded to the data processing equipment under the chain, so that the data processing equipment under the chain can obtain transaction result information according to the transaction proposal data; and finally, receiving the transaction result information sent by the data processing equipment under the chain, recording the transaction result information and sending the transaction result information to the transaction initiator. In this way, the step of obtaining transaction result information from transaction proposal data, which requires more computing resources, is shifted from blockchain to down-chain data processing devices. Because the computational resources of the data processing equipment under the chain can be infinitely increased theoretically, the factors restricting the transaction performance are changed from the capability of the blockchain platform for calculating the transaction result to the capability of the blockchain platform for recording the transaction result. Therefore, the transaction processing speed can be greatly improved, so that the transaction quantity which can be processed by the block chain at the same time is increased, and the transaction throughput is improved.
