Design method for improving fair transaction and efficiency of block chain in industrial Internet of Things

Abstract

The invention provides a design method for improving fair transaction and efficiency of a block chain in an industrial internet of things, and the method comprises the following steps: firstly, inheriting the mining fairness of a fruit chain, and introducing a transaction packaging and propagation strategy; 1) based on transaction selection of geometric distribution, each miner follows the geometric distribution to select and pack transactions so as to balance processing fairness and reduce repeated packing of the transactions, and meanwhile, repeated packing is avoided to a certain extent; and 2) based on TTL transaction propagation, the broadcast range of the transaction is limited by applying time-to-live or hop count limitation of transaction forwarding, the number of repeated transactions in the miner transaction pool is reduced by controlling the propagation of the transaction, and further the repeated packaging of the block chain is inhibited; finally, the transaction selection of the miner is finely adjusted, the fairness of transaction processing is realized, and meanwhile, repeated packaging is greatly reduced; the fairness of transaction processing is realized, and the processing efficiency is effectively improved.

Description

【Technical field】 [0001] The present invention relates to block chain technology, in particular to a design method for improving the fair transaction and efficiency of block chain in industrial internet of things. 【Background technique】 [0002] Blockchain is a technology that integrates key technologies such as consensus algorithms, smart contracts, distributed ledgers, and asymmetric encryption algorithms. It has the characteristics of decentralization, trustless application of rules, and demonopoly of security protection. There are many nodes on the blockchain, and the nodes of the blockchain are network or server members or systems that store data, and can send, receive and verify messages. According to the function, it can be divided into ordinary nodes, backup nodes and super nodes. Among them, ordinary nodes can perform block synchronization and broadcast transactions but cannot perform accounting. Backup nodes have the same functions as ordinary nodes, and also have ...

Problems solved by technology

However, in the FruitChain, miners package transactions in the same mode (namely the order mentioned) to achieve fairness in transaction processing, which will lead to serious repeated packaging problems (that is, many miners package the same transaction into fruit); on the contrary, if miners package transactions without following the same pattern, it will destroy the fairness of transaction processing
