This reward mechanism motivates miners to actively participate in the maintenance and verification of the blockchain to ensure the security and stability of the network. The amount of reward for the new block is allocated according to pre-set rules, usually related to the miner's contribution and the computing power consumed. Block rewards are an important economic incentive mechanism in the blockchain ecosystem, helping to maintain the  operation and development of the network."}]}],"pr":"01cf5ecd57944de27a27b5c52c1211e79c9882526744478f81643cdffded239a"}
