Embodiment Construction

[0055] The present invention: as shown in the figure, a Bitcoin grouping network system based on the Stackberg game, including 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 the set of miners i, where n≥2;

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

[0057]

[0058] where h i Indicates the hash amount of miner i, P is the total amount of compensation 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 estimated by the existing difficulty, and R is the reward obtained after successfully mining a block.

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

Abstract

The invention discloses a Bitcoin grouping network system based on the Stackberg game and an incentive method thereof. This method uses the Stackelberg game to model the relationship between the mining pool platform and the miners. The key steps are: (1) First, calculate the hash amount provided by each miner under the Nash equilibrium solution according to the unit cost of each miner and the set total reward; (2) Then, according to the Nash equilibrium solution, the hash amount provided by each miner is solved (3) Each miner calculates the best hash amount provided to the mining pool platform according to the Stackerberg equilibrium solution; ( 4) Calculate the utility of each miner under the Stackerberg equilibrium solution; (5) Calculate the utility of the mining pool platform under the Stackerberg equilibrium solution. The method of the invention satisfies the characteristics of calculation effectiveness, individual rationality, profitability and uniqueness, and is an effective method for helping the mining pool platform to decide the remuneration and the miners to decide the mining strategy.

Description

technical field [0001] The invention relates to an incentive method for a bitcoin grouping network, in particular to an incentive method based on the Stackerberg game considering the miner's cost. Background technique [0002] A Bitcoin mining pool is a pool of resources where miners share processing power across the network, with rewards distributed based on the amount of work they do 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 the network, distributing rewards based on the amount of work they do to find a block. However, the profit distribution method in most existing mining pools ignores the cost of individual miners. The cost not only exists objectively for each miner, but also varies greatly with regions and hardware performance. Therefore, we fully factor the cost of miners into the incentive method of Bitcoin mining pools. This method can better reflect the o...
