Method for processing delay transaction in advance, device and storage medium

Abstract

The invention provides a method for processing a delay transaction in advance, a device and a storage medium. The method comprises the following steps that: a first verification code and the hash value of the first verification code are generated; a first delay transaction which configures the hash value to be an advanced execution verification parameter is generated, the first delay transaction is sent to a blockchain node, so that the first delay transaction can be stored in a delay cache queue outside a memory pool; a verification code sending instruction inputted by a current user is responded, the first verification code and the transaction hash of the first delay transaction are transmitted to a second user side in a specified mode, so that the second user side generates a first advanced execution transaction according to the first verification code and the transaction hash and sends the first advanced execution transaction to the blockchain node for executing the first advancedexecution transaction; whether the hash value of the first verification code is the same as the advanced execution verification parameter or not is verified; and if the hash value of the first verification code is the same as the advanced execution verification parameter, the first delay transaction is stored in the memory pool in advance. With the method of the invention adopted, the delay transaction can be executed in advance under the condition of passing verification.

Description

technical field [0001] The present application relates to the technical field of block chains, and in particular to a method, device and storage medium for advance processing of delayed transactions. Background technique [0002] In several patent applications previously submitted by the applicant, two transaction delay processing mechanisms on the blockchain were respectively proposed: one is to cache the delayed transaction in the delay cache queue outside the memory pool to pass the delay period ; The other is to submit the delayed transaction to the chain through delayed transaction submission but not execute it temporarily to pass the delay period. [0003] In the above two transaction delay processing mechanisms, once the delayed transaction is sent to the blockchain network, the delayed transaction must pass the specified delay period before it can be executed, resulting in some transactions that need to be executed in advance The business logic cannot be realized. F...

Problems solved by technology

[0003] In the above two transaction delay processing mechanisms, once the delayed transaction is sent to the blockchain network, the delayed transaction must pass the specified delay period before it can be executed, resulting in some transactions that need to be executed in advance The business logic cannot be realized. For example, user A wishes to perform a delayed transfer transaction to user B after user B completes a certain task, so that the delayed transfer transaction can be executed in advance as an incentive to complete the task, etc.
