if yes, go to step S192: deducting the commission fee of the delayed deposit transaction, and storing the delayed transaction to the local.
Specifically, S15 is configured to: the delayed 1s is required to pay the handling fee m, and the delayed handling fee of the delayed credit card transaction is determined according to the delayed time length as an example;
the client generates a delayed evidence storing transaction tx2 according to the delayed transaction tx 1; the payload field of tx2 includes tx1, tx1 includes delay information, and it is assumed that the delay information is t 1;
the blockchain node performs step S11, receiving tx 2;
the block chain node executes the step S13, when it is determined that tx2 is the first type transaction requiring delay, the delay duration of tx1 is determined according to t2, and if the time node for executing tx2 is t1, the delay duration of tx1 is determined to be t2+ t 1;
the blockchain node executes step S15 to determine the delay handling fee of tx2, where the delay handling fee of tx2 is t1 × m;
the blockchain node executes step S17, and determines the lowest total commission fee fe _ min of tx2 according to the basic commission fees of t1 × m and tx 2;
the blockchain node executes step S191 to determine whether fe _ tx2 is not less than fe _ min:
when the fe _ tx2 is not less than fe _ min, step S192 is performed to deduct the commission fee fe _ tx2 of tx2 and store tx1 locally.
In more embodiments, tx1 may also be carried in tx2 according to actual requirements, for example, tx1 is used as an appendix to tx2, which may achieve the same technical effect;

In further embodiments, the delay information of the delayed transaction may be configured in other fields according to actual requirements, for example, when the delay information of the delayed transaction is configured in the signature information, the assets delayed in the delayed transaction may be not only assets in the delayed contract, but also assets of other contracts (i.e. the executor name of the delayed transaction is configured as other contracts outside the delayed contract), or global assets (i.e. the executor name of the delayed transaction is configured as null).
In more embodiments, the manner of determining whether the delayed evidence-storing transaction is the first type of transaction that needs to be delayed may also be configured according to actual requirements, for example, the transaction is configured with a delayed transaction field, when the delayed transaction field of one transaction is empty, the transaction is a transaction that does not need to be delayed, and when the delayed transaction field of the transaction is not empty, the transaction is a transaction that does not need to be delayed, so that the same technical effect may be achieved.
In further embodiments, the method for determining the basic commission of the delayed credit transaction may be configured according to actual requirements, for example, the basic commission is configured as a fixed value, or a floating tariff for calculating the basic commission is determined according to congestion conditions of the blockchain network, and then the basic commission is determined according to a storage space occupied by the delayed credit transaction and the floating tariff, so that the same technical effect may be achieved.
In further embodiments, the S15 may be further configured according to actual requirements, for example, configured to determine the delayed charging fee of the delayed deposit transaction according to a preconfigured delayed charging fee calculation rule, a delayed time length, and a storage space occupied by the delayed transaction, and assuming that the storage space occupied by the delayed transaction is n, the delayed charging fee of the delayed deposit transaction is t1 m n, which may achieve the same technical effect.
The embodiment enhances the safety of the block chain network on the basis of providing the delayed transaction storage service.
Preferably, the determining the delayed charging for the delayed credit transaction according to the pre-configured delayed charging calculation rule and the delayed time duration includes:

determining a delay rate according to the spent storage space and the total storage space of the spent first-class transaction;
and determining the delay handling charge of the delay deposit evidence transaction according to the delay rate, the pre-configured delay handling charge calculation rule and the delay time length.
Specifically, assuming that the total storage space allocated to each block node for storing the first type of transaction is 100M, each block node is allocated with a delay rate policy: when the spent storage space of the spent first type transaction reaches 20M, the required rate doubles for every 10M increase; and assuming a base delay rate of 1;
assume that the spent storage space of the first type of transaction that has been spent at this time is 35M;
determining a delay rate to be 2 by the block chain node;
the blockchain node determines the delay commission of tx2 to be t1 m 2.
The embodiment dynamically adjusts the delay rate, further solves the problem that a large amount of local storage space is occupied, and further ensures the availability of the block chain nodes.
Preferably, the block link point is configured with a first interface for other terminals to obtain the total memory space and the spent memory space.
Preferably, the determining the lowest total commission for the delayed credit transaction based on the delayed commission, the base commission for the delayed credit transaction comprises:
determining a floating rate for calculating a basic handling fee according to the congestion condition of the block chain network;
determining the basic commission charge of the delayed deposit certificate transaction according to the storage space occupied by the delayed deposit certificate transaction and the floating rate;
and determining the lowest total commission charge of the delayed evidence-storing transaction according to the delayed commission charge and the basic commission charge.
