A block reward is the incentive given to a blockchain participant for successfully creating or validating a new block. It typically consists of newly issued cryptocurrency and may also include transaction fees from the block. Block rewards are used in both proof-of-work and proof-of-stake systems to encourage honest participation and network security. In proof-of-work, miners compete to solve cryptographic puzzles, while in proof-of-stake, validators are selected based on staked assets. Over time, block rewards may decrease according to predefined issuance schedules.
