Validator Revenue Models
Validator revenue models describe how those who secure the network are compensated for their work. This revenue typically comes from two main sources: block rewards and transaction fees.
Block rewards are newly minted tokens issued by the protocol to incentivize participation, while transaction fees are paid by users for the services provided by the network. In mature networks, transaction fees become the primary driver of sustainability as block rewards decrease over time.
Validators must manage their costs, including hardware, electricity, and the risk of being slashed for malicious behavior. This economic structure is fundamental to the security of the entire financial system.
If the revenue model is not attractive, the network may struggle to maintain a sufficient number of honest validators. It is a core component of tokenomics that balances security with decentralization.
Participants must evaluate these models to understand the long-term viability and security of a protocol.
