Network transaction method and apparatus based on block chain system

Abstract

The invention discloses a network transaction method and apparatus based on a block chain system. The network transaction method and apparatus based on a block chain system are used for reducing time consuming of transaction and improving concurrency. The block chain system includes multiple levels of block chain network nodes; and the multiple levels of block chain network nodes at least include a first block chain network node of the first transaction party for network transaction, and a second block chain network node of the second transaction party for network transaction. The network transaction method based on a block chain system includes the steps: the first block chain network node generates transaction information corresponding to the network transaction; the transaction information is sent to the second block chain network node of the second transaction party for network transaction; the first block chain network node and the second block chain network node use a consensus algorithm to reach a consensus for the transaction information; and the first block chain network node and the second block chain network node synchronously keep accounts for the network transaction corresponding to the transaction information for which the first block chain network node and the second block chain network node reach a consensus.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a network transaction method and device based on a block chain system. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing paradigm that uses contracts to program and manipulate data. The blockchain technology itself has many advantages: on the one hand, because the blockchain network can realize self-restraint through algorithms, any behavior of maliciously deceiving the system will be repelled and suppressed by other nodes in the network. Therefore, the blockchain system does not need to rely on Secure network transactions can be realized with the support an...

Problems solved by technology

[0004] First of all, since each blockchain node needs to participate in the consensus operation of all network transactions, the system overhead of each blockchain node is relatively large; moreover, each network transaction needs to go through the consensus of all blockchain nodes, resulting in each The efficiency of a network transaction is low; and, since the consensus operation of each transaction requires the participation of all blockchain nodes, multiple network transactions cannot be executed concurrently, reducing transaction efficiency

[0005] Secondly, because the network transaction between any two blockchain nodes needs to be kept by all blockchain nodes, that is: the transaction account corresponding to the network transaction is recorded in the database jointly maintained by all blockchain nodes. Therefore, it leads to a large amount of data in the large ledger, and the large ledger needs to be jointly maintained by each blockchain node, which leads to a large storage overhead and low bookkeeping and audit efficiency

[0006] It can be seen that since the consensus operation and bookkeeping operation in the traditional network transaction method need to be executed jointly by each blockchain node in the system, multiple transactions cannot be executed concurrently and the execution efficiency is low.
