Technical field

The present invention relates to the field of blockchain technology, and in particular, to a transaction processing method, system, electronic device and storage medium based on a blockchain.

Background technique

A blockchain is generally understood to be a distributed ledger, and its nature is also a distributed database. One of its basic functions as a distributed database system is to implement log synchronization for different nodes. Unfortunately, distributed algorithms have an inevitable physical upper limit for their Transaction Per Second (TPS) due to their complexity and unavoidable physical distance between nodes. The current physical upper limit directly leads to the blockchain being difficult to use in many TPS environments requiring up to 6 digits of second traffic (using the PBFT algorithm as an example. In a known environment, the second traffic that generates the protocol is only implemented. A four-digit breakthrough in second-rate traffic).

At present, in the financial field, the more common solution to realize transaction processing using blockchain technology is to integrate multiple transactions into one transaction in different ways and then send them to a blockchain network for calculation. If the transaction is initiated by multiple parties, Then each node needs to broadcast its own transactions to other nodes to ensure that the transaction package will contain its own transactions. However, if for some reason (such as network speed or stability reasons) individual transactions cannot be broadcast to most nodes within a predetermined time, then the transaction is likely to fail for technical reasons. At the same time, in order to reserve the transaction broadcast time to the nodes on the blockchain, the single transaction log generation speed will be directly reduced from the sub-millisecond or millisecond level to the second level (thousands of losses). These issues must be addressed for financial ecosystems that have high requirements for transaction processing stability and transaction processing efficiency.

Then, a transaction shunt control system for transaction shunt control is constructed for each participant of the blockchain network, and the transaction shunt control system is used to manage the nodes of each participant in each chain to manage the blockchain network. Transaction business.

Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of an embodiment of a transaction processing method based on a blockchain according to an embodiment of the present invention.

In an embodiment, the blockchain based transaction processing method comprises:

Step S10, after a user initiates a transaction request to a participant in the blockchain network, the transaction shunt control system of the participant acquires a preset type transaction parameter of the transaction request, and divides the control parameter according to the pre-stored transaction. And determining, by the predetermined analysis rule, an identifier of the parallel blockchain network corresponding to the preset type transaction parameter, where the transaction offload control parameter includes association data of the identifier of the parallel blockchain network and the preset type transaction parameter;

In this embodiment, when a participant in the blockchain network receives a transaction request initiated by the user, the transaction-distributed control system pre-built by the participant acquires a preset type transaction parameter of the transaction request. (eg, transaction date, transaction number, transaction amount, transaction type, etc.), based on transaction fragmentation control parameters pre-stored in the blockchain network, and determining acquired preset type transaction parameters based on predetermined analysis rules The identifier of the corresponding parallel blockchain network, for example, the corresponding parallel block may be determined according to the order of the transaction date, the size or parity of the transaction number, the numerical range of the transaction amount, different transaction types, and the like. The identification of the chain network is not limited here. The transaction offload control parameter includes an identifier of a parallel blockchain network (eg, a number of a parallel blockchain network) and a preset type of transaction parameter (eg, a transaction date, a transaction number, Linked data for transaction amount, transaction type, etc.)

Step S20, the transaction shunt control system of the participant uses the parallel blockchain network corresponding to the identified identifier as the target blockchain network that executes the transaction request, and sends the transaction parameter corresponding to the transaction request to the target block. The chain network performs transaction processing.

After determining the identifier of the parallel blockchain network corresponding to the preset type transaction parameter of the transaction request, the transaction shunt control system of the participant determines the parallel blockchain network corresponding to the identified identifier as the target block for executing the transaction request. The chain network sends the transaction parameters corresponding to the transaction request to the target blockchain network for transaction processing, thereby implementing shunt control of the transaction transaction on the blockchain network.

In this embodiment, a plurality of parallel blockchain networks having the same participant are constructed for a blockchain network, and a transaction shunt control system is constructed for each participant of the blockchain network; when the blockchain network is in the blockchain network After receiving the transaction request, the participant's transaction diversion control system acquires a preset type transaction parameter of the transaction request, and determines a parallel blockchain network corresponding to the preset type transaction parameter based on a predetermined analysis rule. And identifying, the determined parallel blockchain network corresponding to the identifier is used as a target blockchain network for executing the transaction request, and sending the transaction parameter corresponding to the transaction request to the target blockchain network for transaction processing. Since the transaction request can be executed by offloading transaction requests of different participants to different parallel blockchain networks during transaction processing, it is effectively avoided that individual transactions cannot be broadcast to most nodes within a predetermined time. The resulting transaction fails, and there is no need to reserve the transaction broadcast time to the nodes in the blockchain network, which improves the transaction log generation speed and improves the stability and efficiency of the transaction transaction processing.

Further, in other embodiments, the preset type transaction parameter is a transaction number, and the predetermined analysis rule is:

The obtained transaction number is extracted, and the identifier of the parallel blockchain network corresponding to the extracted transaction number is determined according to a mapping relationship between the predetermined transaction number fragment definition formula and the identifier of the parallel blockchain network.

For example, in an embodiment, the mantissa of the acquired transaction number may be extracted, and the parallel region corresponding to the mantissa of the extracted transaction number is determined according to the mapping relationship between the different mantissa of the predetermined transaction number and the identifier of the parallel blockchain network. The identifier of the blockchain network, the identifier of the parallel blockchain network is the identifier of the parallel blockchain network corresponding to the acquired preset type transaction parameter.

In another embodiment, the mantissa of the acquired transaction number may also be extracted to determine the parity property of the extracted mantissa (eg, odd or even), according to the predetermined parity property and the identity of the parallel blockchain network. The mapping relationship determines the identifier of the parallel blockchain network corresponding to the mantissa of the extracted transaction number, and the identifier of the parallel blockchain network is the identifier of the parallel blockchain network corresponding to the acquired preset type transaction parameter.

In still another embodiment, the mantissa of the acquired transaction number may also be extracted, and the parallel blockchain corresponding to the extracted modulus is determined according to the mapping relationship between the modulus of the predetermined transaction number and the identifier of the parallel blockchain network. The identifier of the network, the identifier of the parallel blockchain network is the identifier of the parallel blockchain network corresponding to the acquired preset type transaction parameter.

Further, in other embodiments, the preset type transaction parameter is a transaction type, and the predetermined analysis rule is:

The identifier of the parallel blockchain network corresponding to the acquired transaction type is determined according to a mapping relationship between the predetermined transaction type fragment definition formula and the identifier of the parallel blockchain network.

For example, the preset type transaction parameter is a transaction type such as a roll-out transaction or a transfer transaction, and the parallel block corresponding to the acquired transaction type is determined according to a predetermined mapping relationship between different transaction types and the identifier of the parallel blockchain network. The identifier of the chain network, the identifier of the parallel blockchain network is the identifier of the parallel blockchain network corresponding to the acquired preset type transaction parameter.

Further, in other embodiments, the preset type transaction parameter includes a transaction number and a transaction type, and the predetermined analysis rule is:

Extracting the obtained transaction number, and determining the extracted transaction number and the parallel block corresponding to the acquired transaction type according to the mapping relationship between the predetermined transaction number, the transaction type fragment definition formula and the identification of the parallel blockchain network. The identity of the chain network.

In this embodiment, the identifier of the corresponding parallel blockchain network is determined by considering the transaction number and the transaction type, as in one embodiment, according to a predetermined transaction number (modulo property or the parity property of the mantissa) The mapping relationship between the different transaction types and the identification of the parallel blockchain network determines the extracted transaction number and the identifier of the parallel blockchain network corresponding to the acquired transaction type, and the identifier of the parallel blockchain network is The identifier of the parallel blockchain network corresponding to the obtained preset type transaction parameter.

Further, in other embodiments, the transaction offload control parameter is pre-stored in a smart contract corresponding to a node of each participant of the blockchain network.

The data on the blockchain is usually stored in two places: smart contracts (with their own data state) and transaction logs, each block chain node corresponding to a smart contract And transaction records. In this embodiment, in order to ensure that the transaction offload control parameters invoked by the transaction shunt control system of each participant are consistent and credible, the transaction offload control parameters are pre-stored in each blockchain network (including a blockchain network). And in the smart contract corresponding to each node of each participant of the plurality of parallel blockchain networks constructed for the blockchain network.

Further, after the transaction shunt control system determines the parallel blockchain network corresponding to the identified identifier as the target blockchain network that executes the transaction request, and sends the transaction parameter corresponding to the transaction request to the target blockchain network And analyzing, by the smart contract on the target blockchain network, whether the transaction request is executed according to a transaction offload control parameter pre-stored on the target blockchain network. For example, in an implementation manner, the smart contract on the target blockchain network determines the transaction according to its pre-stored transaction shunt control parameter, that is, the association data of the identifier of the parallel blockchain network and the preset type transaction parameter. The identifier of the parallel blockchain network corresponding to the transaction parameter in the request, and verifying whether the identifier of the determined parallel blockchain network is consistent with the identity of the target blockchain network itself. In another embodiment, the smart contract on the target blockchain network is based on The pre-stored transaction shunt control parameter, that is, the association data of the identifier of the parallel blockchain network and the preset type transaction parameter determines the transaction parameter type corresponding to the identifier of the target blockchain network itself, and verifies the determined transaction parameter type. Whether it is consistent with the type of the transaction parameter in the transaction request. If it is confirmed that the identity of the parallel blockchain network or the transaction parameter type is correct, the transaction request is executed on the target blockchain network to prevent the wrong transaction parameter from being affected by the transaction flow control system. The situation of chain network entry occurs.

Further, as shown in FIG. 3, FIG. 3 is a schematic diagram of downloading a slice definition in an embodiment of a transaction processing method based on a blockchain according to the present invention. In this embodiment, in each blockchain (such as chain 0, chain) 1. On the chain 2), the slice definition download is performed, that is, when the transaction parameters of different preset types and the slice definition of the parallel blockchain network are pre-stored, the blockchain maintenance party sends the slice definition to each chain maintenance. Nodes that can be called (for example, node 1 on each chain), node 1 on each chain will synchronize the fragment definition formula to all nodes through the consensus mechanism on its own chain, when a participant's fragmentation When the system, the transaction shunt control system is started, the fragment definition is downloaded directly from the nodes on each chain, and is used as a reference for subsequent transaction fragmentation.

Further, as shown in FIG. 4, FIG. 4 is a schematic diagram of a fragment definition definition in a blockchain-based transaction transaction processing method according to an embodiment of the present invention. In this embodiment, if a fragment definition change is required, the area is changed. The blockchain maintainer sends the updated fragment definition formula to a node of the callable chain (for example, node 1 of chain 0), and node 1 of chain 0 synchronizes the fragment definition formula to chain 0 through the consensus mechanism on its own chain. Go up all the nodes on it. When the updated slice definition is determined to be written to the blockchain, each node sends a message to their corresponding slice system, the transaction offload control system. After the fragmentation system receives the message that the slice definition has been updated, it will re-download the latest slice definition from the node to complete the change of the slice definition.

Further, as shown in FIG. 5, FIG. 5 is a schematic diagram of a transaction process in a block transaction-based transaction processing method according to an embodiment of the present invention. In this embodiment, when a transaction is performed on a blockchain, for example, Bank A The transaction number txID=00001 is sent to its own fragmentation system, that is, the transaction flow control system. After receiving the transaction, the fragmentation system will transfer the transaction to the blockchain 0 according to the fragment definition formula written on each node. After the transaction is passed to the smart contract on blockchain 0, the smart contract will decide whether to execute the transaction according to the fragmentation logic stored in the chain, that is, the transaction shunt control parameter. For example, the smart contract on blockchain 0 can be stored according to the area. The transaction shunt control parameter on blockchain 0 verifies whether the blockchain network identifier or transaction parameter type corresponding to the transaction is correct. If the determination is correct, the transaction is executed on blockchain 0.

The present invention further provides a transaction shunt control system for processing blockchain transaction transactions. First, construct a plurality of parallel blockchain networks with the same participants for a blockchain network. For example, if a blockchain network has participants A, B, and C, construct multiple parallel regions for the blockchain network. Blockchain network, each parallel blockchain network has the same participants as the blockchain network A, B, C, wherein each participant A, B, C has its own node in each blockchain, that is, the blockchain network has the same participants on multiple parallel blockchain networks. A, B, C, and each participant A, B, C has the same node in each blockchain. Then, a transaction shunt control system for transaction shunt control is constructed for each participant of the blockchain network, and the transaction shunt control system is used to manage the nodes of each participant in each chain to manage the blockchain network.

The traffic distribution module 02 is configured to use the parallel blockchain network corresponding to the determined identifier as the target blockchain network that executes the transaction request, and send the transaction parameter corresponding to the transaction request to the target blockchain network for transaction processing. .

In this embodiment, a plurality of parallel blockchain networks having the same participant are constructed for a blockchain network, and a transaction shunt control system is constructed for each participant of the blockchain network; when the blockchain network is in the blockchain network After receiving the transaction request, the participant's transaction diversion control system acquires a preset type transaction parameter of the transaction request, and determines a parallel blockchain network corresponding to the preset type transaction parameter based on a predetermined analysis rule. And identifying, the determined parallel blockchain network corresponding to the identifier is used as a target blockchain network for executing the transaction request, and sending the transaction parameter corresponding to the transaction request to the target blockchain network for transaction processing. Due to the transaction transaction, The transaction request of different participants can be offloaded to different parallel blockchain networks to execute the transaction request, effectively avoiding the transaction failure caused by the individual transaction not being broadcast to the majority of nodes within the predetermined time, and no need to pre- The transaction broadcast time is given to the nodes in the blockchain network, which improves the transaction log generation speed and improves the stability and efficiency of the transaction transaction processing.
