Definition
Block reward is the amount of new cryptocurrency and/or fees that a blockchain protocol assigns to the creator of a valid block. It is a built-in value that determines how many coins are issued to the successful participant each time a new block is added to the chain. Block rewards are usually defined by the protocol’s monetary rules.
In Simple Terms
Block reward is the payout given when a new block is added to a blockchain. It is the number of coins, and sometimes transaction fees, that the system gives to whoever successfully creates that block, according to the rules written into the blockchain’s code.
Context and Usage
The term block reward is commonly used when discussing how new coins enter circulation and how participants are compensated for supporting a blockchain. It appears in conversations about network security, coin supply, and protocol settings. Block reward values are often tracked as a basic metric of a blockchain’s economic design and long-term issuance schedule.
