As a reward for their services, the validator receives:

1. _Transaction fees_: A sum of tokens or coins paid by users for each transaction included in the block.

2. _Block reward_: A predetermined amount of newly minted tokens or coins, awarded to the validator for creating and adding the new block to the blockchain.

The block reward is designed to incentivize validators to continue validating transactions and creating new blocks, ensuring the blockchain's security, stability, and growth. The transaction fees and block reward provide a financial motivation for validators to perform their duties honestly and efficiently.

In many blockchain networks, the block reward is halved at regular intervals (e.g., every 4 years in Bitcoin) to gradually reduce the supply of new tokens and maintain a stable economic balance. This mechanism helps maintain the network's security and prevents inflation.

By receiving transaction fees and a portion of the block reward, validators are incentivized to continue supporting the blockchain, ensuring its continued operation and development.
