Mining Reward

A mining reward is the total compensation a miner receives for successfully validating a block and adding it to the blockchain. It comprises two components: the block subsidy (newly created cryptocurrency issued by the protocol) and transaction fees paid by users included in the block. The size of mining rewards typically decreases over time through events called "halving," where the block subsidy is reduced by half at predetermined intervals, ultimately creating a fixed maximum supply. Mining rewards serve as the primary economic incentive that motivates miners to invest in hardware and electricity to secure the network. Example: In Bitcoin, miners currently earn 6.25 BTC per block plus transaction fees, with the block subsidy halving approximately every four years—from the original 50 BTC to 25 to 12.5 to its current amount. Each halving reduces the newly created Bitcoin supply, eventually reaching a point where transaction fees become the primary miner incentive. Why it matters for mining and staking: Mining rewards are fundamental to blockchain security economics, directly determining whether mining remains profitable and attracts sufficient computational power. As block rewards decrease over time, the protocol must rely increasingly on transaction fees to sustain security, making reward structure critical for long-term network viability and decentralization.
