Staking rewards are incentives paid to validators for participating in a blockchain network's proof of stake consensus mechanism. They are a reward for helping to secure the network and validate transactions by locking up their coins as a stake in the network.
The rewards received are often proportional to the number of coins staked, with larger stakes earning a greater share of rewards. Staking rewards can come in the form of the blockchain's native currency or sometimes a separate token. They are typically distributed on a regular basis, such as daily, weekly, or monthly.
