# ETH 2 Model assumptions

* ETH2 phase considered in the model
    
    * Are we considering only PoS inflation? Or PoW too?
    
* `MIN_SLASHING_PENALTY_QUOTIENT` value
    
    * We're defining this spec value as `32` (assuming a steady state, but in the docs it's being used a  value of `128`) ![](https://i.imgur.com/0Utsmha.png)

* Model Scale
    
    * Epoch based? 

* Rewards

    * What is the probabilistic distribution of the attestation rewards (derived from attestation inclusion distance)? How to assert the aggregate attestation effectiveness? Will it improve with time as the nodes get more effective)? Points to consider on the attestation inclusion distance > 1 (reference [ethereumstudymaster](https://ethereumstudymaster.com/topic/attestation-inclusion-process/)):
        * **Attestation Generation Delay**
        * **Attestation Propagation Delay**
        * **Aggregate Generation Delay**
        * **Aggregate Propagation Delay**
        * **Block Production Failure**
        * **Malicious Activity**


* Slashing
higher slashing penalties on staking pools?
