Block reward refers to the Bitcoin reward obtained by miners after successfully mining a new block. This reward mechanism encourages miners to invest in computing resources to maintain the security and stability of the blockchain. In the Bitcoin system, the block reward gradually decreases with the increase in mining difficulty to keep the total amount of Bitcoin limited. Transaction fee reward refers to the fees received by miners when processing transactions, which are  paid by both parties involved in the transactions to motivate miners to provide services for the blockchain network. These two reward mechanisms together encourage miners to actively participate in the maintenance and operation of the blockchain, ensuring its continuous development and growth."}]}],"pr":"17b4b7ac6f7d0d8f18a5dd3f37ce5241d307e4abd5c717760b4834183a2a0b80"}
