| Abstract(in English) | It is an important decision-making problem for a miner in blockchain networks if he/she does mining so that he/she earns a reward by creating a new block earlier than the other miners. We formulated this problem as a non-cooperative game and derived Nash equilibria theoretically when the number of miners is 2. In this report, we analyze the relationship between the cost for mining, and Nash equilibria when the number of miners is 3. We show a hysteresis phenomenon of Nash equilibria and a jump phenomenon of the decision of the miners depending on the reward. |
