These miners compete for the right to package transactions by solving complex mathematical problems, which usually require a large amount of computing  power. Once the miners successfully solve the problems and obtain the packaging rights, they will receive corresponding rewards, including newly issued digital currencies and transaction fees. This approach incentives miners to actively maintain the security and stability of the blockchain, while also ensuring its decentralized characteristics. In this process, transaction fees are actually a compensation for the labor and resources invested by miners. In summary, transaction fees in blockchain are paid to miners as a reward for their maintenance efforts."}]}],"pr":"9786626b109d2d20a0257af191af326bc6959685c96f7fff865848d8a2919b4e"}
