During the mining process, miners decrypt the encryption algorithm in the blockchain through computer calculations, verifying the authenticity and effectiveness of transactions. When they successfully mine a new block, miners can receive a certain amount of virtual currency as a reward. For example, in the Bitcoin system, miners can obtain newly generated Bitcoin after each block is solved. In addition, other virtual currencies such as Ethereum and Litecoin also adopt a similar mining model. However,  as mining difficulty increases, revenue gradually decreases, and may not cover costs such as electricity bills. Therefore, miners need to constantly adjust their strategies to optimize efficiency and reduce costs."}]}],"pr":"9a4f8e86a714335537144b64e37c8d953cf0d472a0d56ff933be4eeaeaa0f3a1"}
