摘要：While there is a longstanding concern about the concentration of Bitcoin mining pools, the real evolution doesn’t show this trend. In this paper, we propose a new mechanism through which the Bitcoin mining pools become decentralized, i.e., the uncertain mining reward – Bitcoin transaction fees. In our research, we first use a model to show that a typical risk-averse Bitcoin miner prefers to allocate his computational hash rate into different mining pools when the Bitcoin transaction fees occupy a large fraction of the mining reward. After that, we use the real data from the year 2012 for detailed empirical analysis. We not only diagnose the relationship between the composition of mining reward and the decentralization of Bitcoin mining pools but also use the micro-level panel data to study the dynamics of individual pools. Our study not only connects the evolution of Bitcoin transaction fees to the structure of Bitcoin mining pools but also sheds light on the long-term behavior of the Bitcoin mining industry because the revenue of Bitcoin mining will eventually all come from transaction fees due to the Bitcoin halving events.
