Block Reward is an incentive given to miners every time they successfully add a new block to the blockchain. This incentive is usually in the form of newly minted coins, as well as a portion of the transaction fees on the network.
For example, on the Bitcoin network, every time a miner successfully adds a new block, they receive Bitcoin as a reward. This incentive is a crucial component that keeps the network operating properly and ensures that the supply of new coins remains under control.
