**Claim.** Under HSPoS a node's probability of being selected remains driven by its fungible stake, while the size of the block reward it receives is scaled by a non-fungible reputation multiplier derived from the node's reputation.

**Type.** mechanism  **Support.** argued

**Holds when.**

- HSPoS reward layer applied on top of an existing PoS consensus layer

**Source quote.**

> Thus, while the node probability of being selected is based on the fungible stake, the rewards for the block is adjusted by the non-fungible reputation multiplier which is a function of the node's reputation.
