A form of incentive for the miner who successfully calculated the hash in a block during mining. Verification of transactions on the blockchain generates new coins in the process, and the miner has rewarded a portion of those.

The Bitcoin network is powered by the mining process, where computers work to solve complex math problems to find a block. When a computer solves these equations and finds a block, they are rewarded with Bitcoin. This is called the block reward.

A block reward in cryptocurrency is the incentive given to miners or validators for successfully adding a new block to the blockchain. It serves as a key motivation for participants to secure and maintain the network. The reward usually consists of newly created coins and, in some cases, transaction fees from the block. For example, in Bitcoin, miners currently receive a set number of bitcoins for every block they mine, but this reward decreases over time through a process called halving. Block rewards help control the supply of new coins and maintain network stability. As rewards decline, transaction fees are expected to become a more significant source of income for miners, ensuring continued blockchain security.
