Problems solved by technology

However, since each node needs to maintain the MPT composed of a full amount of user information, each transaction can only be confirmed after the consensus of all nodes, so the performance pressure on each node is relatively high, and the transaction processing efficiency is low, which cannot meet the requirements of high-level transactions such as banks.

Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] This embodiment discloses a transaction method based on partition consensus, which is applied to a transaction system based on partition consensus. The transaction system includes a plurality of common nodes. Common nodes can be banking institutions or third-party payment institutions. According to the user's transaction account, multiple ordinary nodes are divided into different consensus partitions. The consensus partition is responsible for maintainin...

Abstract

The invention provides a transaction method and system based on partition consensus, the transaction system comprises a plurality of common nodes, each common node corresponds to a plurality of users,and the plurality of common nodes are divided into different consensus partitions according to transaction accounts of the users; and when the first user and the second user of the two transaction parties are located in the same consensus partition, the consensus partition receives a transaction request sent by the first user, each node in the consensus partition verifies the transaction, recordsthe transaction into the block chain after consensus, and sends transaction success information to the first user and the second user. According to the invention, the transaction processing efficiency of the distributed account book system is improved based on a partition consensus mechanism on the basis of ensuring that the service fault or exit of a single node does not affect the normal transaction of a whole network user.

Description

technical field [0001] The present invention relates to the technical field of blockchain, and more specifically, to a transaction method and system based on partition consensus. Background technique [0002] Traditional financial transaction systems, such as banking systems, have a centralized structure. If there is a single point of failure, the users responsible for the institution will not be able to conduct transactions normally. [0003] In order to solve the above problems, distributed ledger technology, that is, blockchain technology, can be used. Most of the existing distributed ledger technologies based on the "account balance" model use the MPT (Merkel-Patricia tree) structure to maintain the account status of all users, such as balance information. When packing the block, the root hash value of the tree is recorded in the block header, which is used to verify the consistency of the data maintained by each node. However, since each node needs to maintain the MPT...
