# 4.2 Token Value and Incentive Structure

PEM tokens serve various functions within the PemChain ecosystem. Primarily, PEM tokens are used as transaction fees to cover the costs required to maintain the network. Additionally, users holding PEM tokens gain the right to participate in governance, contributing to the decision-making process of significant blockchain matters.

PemChain offers a variety of incentives to token holders to encourage their participation in the ecosystem. The main incentive models are as follows:

* Node Rewards: Validator node operators receive PEM tokens as rewards for block validation and network management. Rewards are differentially allocated based on the performance, availability, and contributions of the validator nodes.
* Staking Rewards: PEM token holders can stake their tokens to contribute to network security and earn rewards. The staking reward rate varies depending on the duration and amount staked.
* Governance Participation Rewards: PEM token holders can actively participate in blockchain governance and earn additional rewards through meaningful proposals and voting activities.
