Block Reward

The newly created Bitcoin awarded to the miner who successfully adds the next block to the blockchain, serving as both the mechanism for new Bitcoin issuance and the primary incentive for mining.

Every time a Bitcoin miner successfully solves the cryptographic puzzle required to add a new block to the blockchain (roughly every 10 minutes), they receive a block reward consisting of newly minted Bitcoin plus any transaction fees from the transactions included in that block. The block reward started at 50 BTC in 2009 and decreases by 50% at every halving event.

The block reward serves two critical functions simultaneously: it creates new Bitcoin and distributes it into circulation (the issuance function), and it compensates miners for the substantial electricity and hardware costs required to secure the network (the incentive function). Without the reward, rational miners would have no economic reason to contribute computing power to validate transactions and maintain the blockchain's integrity.

As block rewards diminish over successive halvings, Bitcoin's security model shifts increasingly toward transaction fees. By 2140, when the final Bitcoin is issued and the block reward reaches zero, miners will be compensated entirely by fees. Whether transaction fees alone will provide sufficient mining incentives to maintain network security is an important open question in Bitcoin's long-term design that is not expected to become critical for many decades.
