**Claim.** In conventional Proof of Stake, selection probability for block rewards rises with stake and block rewards are constant regardless of node reputation, whereas in Secure Proof of Stake nodes with higher reputation have a higher probability of being selected for rewards.

**Type.** definitional  **Support.** asserted

**Holds when.**

- comparison of conventional PoS and SPoS reward selection
