Fig. 2 schematically shows a flow chart of a blockchain network based transaction method according to an embodiment of the present disclosure.

As shown in fig. 2, the blockchain network-based transaction method of the embodiment includes operations S201 to S204. The block chain network comprises a supervision node and M consensus nodes; intelligent contracts for managing transaction sequences are deployed on the blockchain network.

The policing system may comprise, for example, a system installed on a client, which may be, for example, a node in the Fabric system, or may be an external device separate from the Fabric system. The targeted transaction information may include, for example, funding information. The target item information may include, for example, contract information, funds payer information, and funds recipient information.

The target consensus node may include nodes associated with a units, B units, C units, and D units.

In operation S202, the association logic corresponding to the target item information in the intelligent contract is invoked to determine the transaction sequence of each target consensus node.

According to an embodiment of the present disclosure, the association relation logic corresponding to the target project information may be determined, for example, according to contract information associated with the target project information.

For example, after a project is initiated by a project building entity, the project building entity enters into a first contract with a general contractor and then enters into a second contract with the general contractor and a supplier. The order of the trades for the project is to first execute the trades with the project building units and the general contractors and to execute the trades between the general contractors and subcontractors.

In operation S203, a target transaction event corresponding to the target transaction information is generated according to the transaction sequence, so that each target consensus node performs consensus processing on the target transaction event based on a preset consensus mechanism, and a consensus result is generated.

According to embodiments of the present disclosure, a targeted transaction event may include, for example, a plurality of transaction split events. The transaction split event may be determined by a transaction sequence, for example. For example, where a construction project includes two trading activities according to a trading order, the number of trade sub-events associated with the construction project may include two. Wherein, each transaction event corresponds to a transaction action.

In operation S204, in case that the consensus result satisfies the consensus condition, the target transaction event is recorded in the blockchain.

It should be noted that the above embodiments are only exemplary embodiments, and the target item information may also include other information according to specific implementation needs.

According to embodiments of the present disclosure, the first transaction event may include, for example, a first transaction consensus node and a funding transaction value determination. The first transaction consensus node may comprise, for example, a node associated with the funds payer information and the funds recipient information.

For example, the node associated with the funds-payer information is a payment node associated with a first financial institution, the node associated with the funds-receiver information is a receiving node associated with a second financial institution, and the funds-transaction value is K. The first transaction event is the transfer of K funds in the funds payer information to the funds recipient information in the receiving node by the payment node.

According to an embodiment of the present disclosure, the second transaction event corresponds to the description of the first transaction event, and is not described herein again.

According to an embodiment of the present disclosure, after determining a plurality of first and second transaction events, a target transaction event is generated from the first and second transaction events.

According to an embodiment of the present disclosure, in case that the consensus result satisfies the consensus condition, recording the target transaction event in the blockchain comprises:

in the event that the consensus result corresponding to the first transaction event satisfies the consensus condition, recording the first transaction event in the blockchain. And recording the second transaction event in the block chain under the condition that the preset time threshold is reached and the consensus result corresponding to the second transaction event meets the consensus condition.

According to embodiments of the present disclosure, after recording the first transaction event in the blockchain, funds associated with the first transaction event are transferred from the payer account to the receiver account. In this case, in the case of the second transaction event, in order to be able to guarantee the supervision of the funds and in order to be able to finally reach the funds into the account of the recipient associated with the second transaction event, the funds may be blocked, for example, in the account of the recipient associated with the first transaction event. The situation that the fund is stolen in the target execution event, so that the fund chain is broken is prevented.

It should be noted that the above embodiments are only exemplary embodiments, and in the case that there are multiple transaction split events in the target transaction event, the funds of each of the other receivers may be frozen before the funds are transferred to the final receiver.

For example, if the target event includes an A event, a B event, and a C event in the order of the transaction. The funds with the recipient in the a and B events may be frozen. When the receiver in the event A or the event B needs to transfer the fund out, the fund is unfrozen.

The funds are thawed again when the second transaction event is executed. After the second transaction event is performed, the funds arrive in the labor sub-package 303 account, at which point the funds may be frozen in the labor sub-package 303 account. When the third transaction event is executed, the fund is unfrozen.
