In operation S202, association logic corresponding to the target item information in the smart contract is called to determine a transaction order of each target consensus node.
According to embodiments of the present disclosure, association relationship logic corresponding to target item information may be determined, for example, from contract information associated with the target item information.
For example, after a project is initiated by a project construction unit, the project construction unit signs first contract information with a general contractor, and signs second contract information with the general contractor and a provider. The order of the transactions for the project is to first perform transactions with project building units and the contractors, and transactions between the contractors and subcontractors are performed.
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 generates a consensus result.
According to embodiments of the present disclosure, the target transaction event may include, for example, a plurality of transaction sub-events. The transaction sub-events may be determined, for example, by a transaction order. For example, in the case where a construction item includes two trade actions according to a trade order, the number of trade sub-events associated with the construction item may include two. Wherein each transaction sub-event corresponds to a transaction action, respectively.
In operation S204, in the event that the consensus result satisfies the consensus condition, the target transaction event is recorded in the blockchain.

According to an embodiment of the present disclosure, the first transaction order has a higher transaction priority than the second transaction order. When executing the target transaction event associated with the target item information, a first transaction event associated with a first transaction sequence is executed, and then a second transaction event associated with a second transaction sequence is executed.
It should be noted that the above embodiments are merely exemplary embodiments, and the number of transaction sequences may include any number, as required by a specific implementation.
According to an embodiment of the present disclosure, generating a target transaction event corresponding to target transaction information according to a transaction order includes:

It should be noted that the above embodiments are only exemplary embodiments, and the target item information may also include other information according to the specific implementation needs.
According to an embodiment of the present disclosure, the first transaction event may include, for example, a first transaction consensus node and a funds transaction value determination. The first transaction consensus node may comprise, for example, a node associated with funds payer information and funds receiver information.
For example, the node associated with the funds-payer information is a payment node associated with the first financial institution, the node associated with the funds-receiver information is a receiving node associated with the 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 recipient node via the payment node.
According to the embodiments of the present disclosure, the second transaction event corresponds to the description of the first transaction event, and will not be described herein.
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.

the status of the transaction resource associated with the first transaction event is determined to be a frozen status, wherein the frozen status is used to characterize the transaction resource as unavailable.
According to embodiments of the present disclosure, after the first transaction event is recorded in the blockchain, funds associated with the first transaction event are transferred from the payer account to the recipient account. In this case, in the presence 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 in the account of the recipient associated with the second transaction event, the funds may be frozen, for example, in the account of the recipient associated with the first transaction event. Preventing the above funds from being moved during the execution of the target event, resulting in a broken funds chain.
It should be noted that the above embodiments are only exemplary embodiments, and in the case where there are multiple transaction sub-events in the target transaction event, the funds of each other recipient may be subjected to the freezing process before the funds are transferred to the final recipient.
For example, if the target event includes an A event, a B event, and a C event in the transaction order. The funds with the recipient in the a event and the B event may be frozen. And when the receiver in the event A or the event B needs to transfer out the funds, thawing the funds.

It should be noted that after the first transaction event is performed, the funds reach the contractor 302 account, at which point the funds may be frozen in the contractor 302 account. The fund is then thawed upon execution of the second transaction event. After the second transaction event is performed, the funds reach the labor subcontracting 303 account, at which point the funds may be frozen in the labor subcontracting 303 account. And thawing the fund when the third transaction event is executed.
