Block chain based transaction timeout control method

Abstract

The invention discloses a block chain based transaction timeout control method, which is characterized in that a user needs to set a timeout limit for a transaction when initiating a transaction, the timeout limit can be a timestamp or a block height, a node firstly judges the timeout limit when packaging the transaction, the transaction is packaged if the transaction does not exceed the timeout limit, the transaction is discarded if the transaction exceeds the timeout limit, the user monitors a block chain in real time, the transaction is regarded to be failed if the transaction of the user is not packaged into a block after the timeout limit is exceeded, and the user needs to initiate the transaction again and does not need to wait any longer. According to the invention, a clear timeout mechanism is set for a transaction of the user on the block chain, and probabilistic estimation on whether the transaction can be on the chain or not is not required any longer, thereby being convenient for the user to perform a timeout processing operation on a client.

Description

technical field [0001] The invention relates to a block chain-based transaction timeout control method. On the basis of the existing block chain technology, a transaction timeout-related protocol and processing method are added to enhance the user's ability to control transaction delays in a distributed system and simplify It defines the timeout processing logic in the upper-level business. Background technique [0002] Blockchain is a new distributed technology. It consists of sequentially arranged transactions to form blocks, and then sequentially arranged blocks to form a chain. Each block contains a self-increasing height as a number, and also There is a timestamp used to record the packing time. The security of user data depends on the public-private key system. Only transactions signed by the user's private key are legal transactions, so others cannot initiate them on behalf of others, and each transaction only has a unique ID to ensure that it cannot be initiated rep...

AI Technical Summary

Problems solved by technology

The security of user data depends on the public-private key system. Only transactions signed by the user's private key are legal transactions, so others cannot initiate them on behalf of others, and each transaction only has a unique ID to ensure that it cannot be initiated repeatedly

[0003] Users need to actively sign a new transaction and broadcast it into the network for each operation. However, due to the distributed nature of the network, there is a certain probability of loss of the transaction. Due to various factors such as the irregular block time interval, users cannot immediately get the response result of whether their transaction is packaged or not. If the result of entering the block is reached, it is inferred that the transaction may be lost or may have failed, and the covering transaction needs to be re-initiated, but there is still a certain probability that the previous transaction will be packaged into the block during this period
