 ## Block Reward
 ---
 
-Block rewards in blockchain are a form of incentive that is given to validators who participate in the process of adding new blocks to a blockchain network. The process of adding new blocks to a blockchain is known as validating in delegated proof-of-stake (DPoS) blockchains.
+Block rewards in a blockchain serve as an incentive for validators who actively contribute to the creation of new blocks within the blockchain network. This rewarding process, commonly referred to as validation, is particularly relevant in **delegated proof-of-stake (DPoS)** blockchains.
 
+In DPoS blockchains, validators are selected to validate transactions and generate new blocks based on the quantity of XPLL they have staked within the network. As a reward for their contributions, validators receive a share of the transaction fees and a portion of the block rewards for successfully creating new blocks.

-Block rewards serve several purposes in blockchain networks. They incentivize miners and validators to participate in the network's consensus process, which helps to maintain the security and integrity of the network. Block rewards also provide a way to introduce new XPLL into circulation, which helps to ensure that the network is sustainable in the long term.
+Block rewards play a crucial role in blockchain networks by serving multiple purposes. They incentivize miners and validators' participation in the network's consensus process, thereby upholding the security and integrity of the network. Additionally, block rewards facilitate the introduction of new XPLL into circulation, ensuring the long-term sustainability of the network.
 
 
 Reward formulas can be found in the technical documentation [parallelchain-protocol](https://github.com/parallelchain-io/parallelchain-protocol/blob/master/Runtime.md).
 
 ### Reward Rate
 
-Over time, the block reward amount decreases as more blocks are added to the blockchain. This is known as the block reward halving, and it is a feature of many blockchain networks, including Bitcoin. The block reward halving helps to control the supply of cryptocurrency and prevent inflation.
