Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of a method for advanced processing of delayed transactions at a user end according to an embodiment of the present invention.
As shown in fig. 1, in this embodiment, the present invention provides a method for advanced processing of delayed transactions applicable to a user side, including:
s12: generating a first verification code and a hash value of the first verification code;
s14: generating a first delayed transaction with the hash value configured to execute the verification parameter in advance, and sending the first delayed transaction to a block chain node for storing the first delayed transaction in a delayed cache queue outside the memory pool;
s16: responding to a verification code sending instruction input by a current user, transmitting a first verification code and transaction hash of a first delayed transaction to a second user end in an appointed mode, so that the second user end generates a first advance execution transaction according to the first verification code and the transaction hash and sends the first advance execution transaction to a block chain node for execution, and verifying whether a hash value of the first verification code is the same as an advance execution verification parameter: if yes, the first delay transaction is stored in the memory pool in advance.
The method is exemplified by offering the parent a to the child b when starting a study, giving the toy a as a reward if the examination in the interim or the examination at the end of the interim achieves a specified score, and giving the toy a as a vacation gift if the goal is not achieved (the toy a is awarded at the end of the holiday if the examination in the interim is achieved, and the toy a is awarded at the vacation if the examination in the interim or the examination at the end of the holiday is not achieved).
In step S12, the user end of the user a generates the verification code m and the m hash value hash (m);
in step S14, the user side of the first generates a delayed transaction tx1 of the redemption ticket of the second transfer toy a after the school term is over, configures the advanced execution verification parameter of tx1 as hash (m), and sends the signed tx1 to the blockchain node.
And the blockchain node receives and broadcasts tx1, and stores tx1 in a delay cache queue outside the memory pool after judging that tx1 is delay transaction.
When the examination achievement in the second period meets the appointed achievement, the first user inputs the verification code to send a command, and in step S16, the first user transmits the verification code m and the transaction hash (tx1) to the second user through any means commonly used in the art. For example, a two-dimensional code is generated from the verification code m and the transaction hash (tx1) and displayed for collection and decoding, or m and hash (tx1) are sent directly through an instant messenger, and so on.
And after the user side of the second user acquires the m and the hash (tx1), generating a transaction tx2 executed in advance and sending the transaction tx2 to the blockchain node.
The blockchain node receives, broadcasts and packages tx2, executes tx2 through a delayed trade contract, finds tx1 according to the hash (tx1) in tx2, and verifies whether the hash value of m in tx2 is the same as the hash (m) in tx 1:
if not, tx2 fails;
if yes, tx2 is executed successfully, tx1 is stored into the memory pool in advance, so that tx1 is packed in advance to execute: if the execution is successful, the redemption ticket of the toy A is transferred to the second, so that the second can redeem the toy A at the designated redemption place by the redemption ticket.
At this point, the user of the first can send a further delay transaction tx3 in the same manner to issue a subsequent (end of term, holiday) award.
And when the examination result in the second period does not accord with the appointed result, the first device does not provide the verification code m to the second device according to the appointment and waits for the examination result at the end of the period to be discharged.
The method is exemplarily described by taking the example that parents issue rewards to children, and in further embodiments, the method can be applied to different scenes and business logics, and the same technical effect can be achieved.
In the above embodiment, the hash value of the verification code is configured as the advanced execution verification parameter in the delayed transaction, and the advanced execution mechanism for verifying the verification code submitted by the advanced execution transaction according to the advanced execution verification parameter and executing the delayed transaction in advance when the verification is passed is configured in the delayed contract on the blockchain, so that the advanced execution of the delayed transaction can be triggered by sending the advanced execution transaction as long as the user obtains the verification code, and the delayed transaction can be executed in advance under the condition of passing the verification.
