Quick answer
A block reward is the compensation paid to the miner or validator that produces an accepted block.
What is Block reward?
A Bitcoin block reward is mainly the newly issued subsidy plus the transaction fees included in the block. The subsidy follows the protocol schedule and is reduced at halving intervals; fees vary with demand.
The useful way to approach this term is to separate its definition from the assumptions people often attach to it. In crypto, the same word can appear in a protocol rule, a user interface, a market-data label, or a marketing claim. Check which layer the explanation is describing.
Why does block reward matter?
The block reward helps explain why miners spend money on electricity and hardware. It also explains why halvings change the economics of mining without changing the rules for previously confirmed coins.
Concrete example
See it in a real situation
After the 2024 Bitcoin halving, the scheduled subsidy became 3.125 BTC per block. A miner’s actual gross reward can be higher if the block also contains transaction fees, but the subsidy and fees are separate components.
Common misconceptions
What this term does not mean
- The reward is not a guaranteed profit; operating costs can exceed the coins and fees received.
- A block reward is not the same as the total value of every transaction in the block.
