# Node Roles

PIJSChain defines three primary node roles. These roles are not mutually exclusive, meaning that a single physical machine may perform multiple functions depending on how it is configured and operated.

**1) Block Producer Node**

**2) Staking Node (Consensus Participation Node)**

**3) Full Node**

Design Principle:\
In PIJSChain, nodes are not merely state synchronizers. They form the operational infrastructure of consensus itself. Even a non-staking Full Node contributes to the network through verification and data propagation, while staking-based rewards are strictly conditioned on real infrastructure contribution. This ensures that economic benefits remain aligned with measurable participation.
