What Is block reward and How Does It Work in Crypto?

A block reward is the incentive given to miners or validators for successfully adding a new block of transactions to a blockchain. In simple terms, block reward is how blockchain networks motivate participants to secure and maintain the system. Without this mechanism, there would be little reason for users to contribute resources to validate transactions.

At its core, block reward is earned when a participant confirms transactions and adds them to the blockchain. In Proof of Work systems, miners compete to solve complex problems, and the first to succeed receives the block reward. In Proof of Stake systems, validators earn rewards based on the amount of cryptocurrency they stake and their role in securing the network.

A block reward usually includes two parts: newly created coins and transaction fees from the block. This process introduces new tokens into circulation while also rewarding network participants. Over time, many blockchains reduce the block reward, which can create scarcity and impact the overall supply of the asset.

Ultimately, understanding block reward is key to understanding how blockchain networks operate. It supports security, decentralization, and fair distribution of new coins. As rewards decrease over time, transaction fees play a larger role, ensuring that the network remains sustainable and efficient in the long run.
