Block chain sustainable mining method and system

Abstract

The invention belongs to the technical field of finance and particularly relates to a block chain sustainable mining method and system. By setting a transaction tax and fee mechanism, original systemic mining rewards is compensated or replaced such that a mining process is stable. A special account for taxes and fees is set by using a chain data structure, the collection of the taxes and fees andmining reward payment are verified through consensus, and the transaction tax and fee management is achieved. A sliding window averaging algorithm based on double-threshold control is used to calculate a transaction tax rate, and the stability and reliability control of a tax balance is carried out. By setting the transaction tax and fee mechanism and setting the special account for the taxes andfees, the collection and management of the taxes and fees are achieved. By using the chain data structure and a block chain consensus process, the openness and security of the transaction tax management are realized. A series of system performance indicators are verified through computer simulation, and a result shows that the issue of block chain mining sustainability can be effectively solved bya proposed new solution.

Description

technical field [0001] The invention belongs to the field of financial technology, and in particular relates to a blockchain sustainable mining method and system. Background technique [0002] One of the supporting mechanisms of the blockchain-based transaction system (hereinafter referred to as the transaction system) is to generate virtual digital currency through mining, thereby forming the economic ecology of the transaction system. Mining is to obtain the bookkeeping right of the blockchain by competing to calculate the hash problem, and block the transaction information in the system. At the same time, the miners who win the bookkeeping right will get a certain amount of virtual currency as mining rewards. In other words, mining has two contributions to the trading system: one is the only way to issue (generate) virtual digital currency; the other is to control the generation of blocks. The mining reward is the incentive for miners to mine, and it is also the basis fo...

Problems solved by technology

[0007] The blockchain-based transaction system issues digital currency through the mining reward process. However, for the stability of the economic ecology, the total amount of digital currency issuance is limited. Therefore, the systematic rewards in the blockchain mining process will gradually decrease to Zero, making the mining process unsustainable; in addition, even if the existing trading system introduces a tip mechanism, due to the dynamics of transactions and the randomness of tip payment, it is still difficult to guarantee the stable income of miners, so it is difficult to guarantee the reliability of the blockchain.
