Method and device for generating block chain continuous transaction sequence number, block chain network node

Abstract

The invention provides a block chain continuous transaction serial number generation method and device, and a block chain network node. The method includes: obtaining the serial number generation request of the client through the block chain network, obtaining the world state serial number according to the serial number generation request, and the world state serial number at least includes the world state serial number counter value; according to the preset generation rule, using The world state number counter value generates a transaction number, and the transaction number includes at least the transaction number counter value; compare the transaction number counter value with the latest world state number counter value, and update the world state number according to the comparison result. The present invention uniformly generates non-repetitive and continuous transaction serial numbers through blockchain network nodes, and can identify transaction sources and other information through transaction serial numbers, avoiding transaction serial number conflicts and reducing system efficiency, improving system availability, and improving transaction retrieval, Statistical processing efficiency.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain continuous transaction serial number generation method and device, and a block chain network node. Background technique [0002] With the gradual maturity of blockchain technology, blockchain technology is gradually applied in fields such as network security, healthcare, financial services, manufacturing and industry, government affairs, charity, retail, real estate, transportation, tourism, and media. However, in some application scenarios, it is also found that there are some functional defects in the blockchain technology. Currently, continuous transaction numbers cannot be generated in the blockchain network. Such as figure 1 As shown, each peripheral application (client) connects to the blockchain network, calls the smart contract, and finally submits the transaction to the k-v database of the blockchain (the world state of the blockchain). The k-v datab...

Problems solved by technology

This kind of key-value conflict leading to failure is acceptable when the transaction frequency is low, but once the blockchain technology is used in a business scenario with a high transaction frequency, this situation will lead to a waste of system resources and affect the system. availability and reliability

At the same time, the transaction number has no uniform rules and is not continuous, which brings great inconvenience to the retrieval and statistics of blockchain transactions (the serial number 10001 does not mean that this is the 10001st transaction)
