Reward structure refers to the system that determines how participants in a blockchain network are compensated for their contributions. This often includes miners and validators who help secure and maintain the network.In many blockchain systems, rewards are given in the form of tokens. For example, in proof-of-work models like Bitcoin, miners receive newly minted coins for solving complex mathematical problems. This incentivizes them to invest time and resources into securing the network.In proof-of-stake systems, validators are rewarded for holding and staking their coins to validate transactions. The more coins they stake, the higher their chances of being chosen to create new blocks and earn rewards.Reward structures can also include transaction fees that participants earn when processing transactions on the network. These rewards vary based on network conditions, and designs may evolve to ensure fairness, scalability, and security.Overall, the reward structure plays a crucial role in motivating users to contribute to the network’s functionality and stability.
