Embodiment Construction

[0055] The present invention: as shown in the figure, a Bitcoin grouping network system based on the Stackelberg game includes a mining pool, the mining pool includes a mining pool platform and a number of miners i, and there is a set M in a mining pool, The M={1, 2,...,n} is a set of miner i, where n≥2;

[0056] Let the utility function of any miner i be:

[0057]

[0058] Among them, h i Indicates the hash amount of miner i, P is the total reward paid by the mining pool platform, k i is the unit cost of miner i;

[0059] Let the utility function of the mining pool platform be:

[0060]

[0061] Among them, A is the total computing power in the Bitcoin network, which is obtained through the existing difficulty estimation, and R is the reward obtained after successfully digging a block.

[0062] Miners i use their computing resources to provide hashing for the platform; in this process, miners will spend a certain cost k; therefore, they expect to be rewarded for the...

Abstract

The invention discloses a bitcoin packet network system based on a Stackelberg game and an excitation method thereof. According to the method, a relationship between a mine pool platform and miners ismodeled by adopting a Stackelberg game. The method comprises the following key steps: (1) firstly, calculating the hash amount provided by each miner under a Nash equilibrium solution according to the unit cost of each miner and a set total reward amount; (2) calculating the optimal total reward of the mine pool platform according to the hash amount provided by each miner under the Nash equilibrium solution, thereby obtaining a Stackelberg equilibrium solution; (3) calculating the optimal hash quantity provided for the ore pond platform by each miner according to the Stackelberg equilibrium solution; (4) calculating the utility of each miner under the Stackelberg equilibrium solution; and (5) calculating the utility of the mine pool platform under the Stackelberg equilibrium solution. Themethod provided by the invention meets the characteristics of calculation effectiveness, individual rationality, profitability and uniqueness, and is an effective method for helping a mine pool platform to decide rewards and helping miners to decide mining strategies.

Description

technical field [0001] The invention relates to an incentive method for a bitcoin grouping network, in particular to an incentive method based on Stackelberg game in consideration of miners' cost. Background technique [0002] Bitcoin mining pools are resource pools where miners share processing power across the network, distributing rewards based on the amount of work they put in to find a block. In the context of cryptocurrency mining, a mining pool is a pool of resources shared by miners who share their processing power across a network, distributing rewards based on the amount of work they put into finding a block. However, most of the profit distribution methods in existing mining pools ignore the cost of individual miners. The cost is not only objective for each miner, but also varies greatly with different regions and hardware performance. Therefore, we fully take the cost factor of the miners into the incentive method of the Bitcoin mining pool. This method can be...
