Disordered transaction control method based on block chain account model

Abstract

The invention discloses a disordered transaction control method based on a block chain account model. The disordered transaction control method based on a block chain account model is characterized in that based on an account model, a user utilizes a unique ID (such as UUID) taken from an increment digital number as the unique identifier for transaction; a node determines whether the behavior of double expenditure exists by determining whether a new transaction ID exists in a historical transaction ID list of the user; an order dependence relationship does not exist between the transaction IDs; an accounting node can packing the transactions into blocks in any order; and the successive dependence relationship of the service layer between the transactions can be guaranteed when a client issues a transaction without influencing disordered packing of the accounting node. The disordered transaction control method based on a block chain account model utilizes the unique ID to prevent double expenditure and playback attack, enables the transaction to not depend on the fixed order, and can use a disordered mode to directly enters the chain, thus satisfying the scene requirement for single-account high concurrent transaction of the client, and avoiding the situation that other transactions are postponed after the transactions are lost in the past.

Description

technical field [0001] The invention relates to a disordered transaction control method based on a block chain account model, which improves the existing rules about orderly transactions in the block chain based on an account model, adds control rules related to disordered transactions, and prevents double transactions Spend related strategies. 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 transaction sent by the user using the private key signature is packaged by the bookkeeping node into the blockchain storage after broadcasting, and the bookkeeping node broadcasts it to other read-only nodes for verification. The legality of the transaction is determined by the user's signature, and the user needs to ...

AI Technical Summary

Problems solved by technology

However, due to the distributed nature of the blockchain network, transactions may be out of order or lost in the process of broadcasting. If the accounting node finds that the transactions are not added in sequence, it will be considered as an illegal transaction and discarded or postponed.

The most serious situation is that a transaction with a certain number in the middle is lost, which will cause all subsequent transactions to be discarded or packaged temporarily, and the client cannot get feedback quickly, so it can only wait for a random time to re-initiate the lost transaction
