What is Block Reward?
Crypto Glossary Definition
The amount of a given cryptocurrency that is rewarded to miners when the next block has been mined.
Why Block Reward Matters
The block reward is the newly minted cryptocurrency (plus transaction fees) paid to whoever successfully mines or validates a block — it's the primary incentive that keeps miners/validators securing the network, and it typically decreases over time on a fixed schedule (see Halving).
Block Reward in Practice
A solo miner running a modest home mining rig finally succeeds in mining a Bitcoin block after months of contributing hash power to a mining pool without personally finding one. For that single block, they receive the block reward - a fixed amount of newly created Bitcoin, plus the sum of all the transaction fees paid by users whose transactions were included in that block. This reward is the entire economic reason miners spend money on hardware and electricity in the first place: without it, there would be no financial incentive to dedicate computing power to securing the network and validating transactions honestly. The miner also knows this reward isn't fixed forever - Bitcoin's protocol cuts the block reward in half roughly every four years in an event called the halving, which has already reduced the reward from an original 50 BTC per block down to a small fraction of that today. As the block reward continues shrinking over time, transaction fees are expected to make up a larger share of what miners actually earn, which is part of the long-term design intended to keep the network secure even after new coin issuance eventually approaches zero. For now, though, the freshly mined coins land straight in the miner's wallet as a very literal payment for helping keep the ledger honest.
