# Staking Rewards on EWX

#### Reward Mechanism <a href="#reward-mechanism" id="reward-mechanism"></a>

* **Reward Source:** Annual inflation = **2.5M EWT** newly minted
  * **80% (2.0M EWT)** → Growth rewards for collators & delegators
  * **20% (0.5M EWT)** → Community Fund Treasury
* **Reward Calculation Flow:**
  1. **Performance-based allocation:** Rewards per era are distributed to collators proportional to their **points** (blocks authored, equivocation handling, etc.).
     * `total_reward_for_candidate = (collator_points / total_points) * total_staking_reward`
  2. **Stake-based subdivision:** Each collator’s allocation is split pro-rata between collator self-stake and delegator stake.
     * `candidate_reward = (candidate_stake / candidate_total_stake) * total_reward_for_candidate`
     * `nomination_reward = (nomination_stake / candidate_total_stake) * total_reward_for_candidate`
  3. **Collator commission (validator tax):** **10%** fee applied to delegator share.

#### Reward Timing <a href="#reward-timing" id="reward-timing"></a>

* **Era length:** **7,200 blocks** (\~24 hours).
* **Growth period length:** **28 eras** (\~28 days).
* **Reward payout delay:** **2 eras** after the end of reward period.
* **Unstaking delay: 2 eras**

#### Transaction Fees <a href="#transaction-fees" id="transaction-fees"></a>

* Collected fees form an additional reward pot.
* Distributed per era using the same **points → stake → commission** logic as growth rewards.

#### Validator / Collator Parameters <a href="#validator-collator-parameters" id="validator-collator-parameters"></a>

* **MaxCandidates:** 100 (max collators in the pool).
* **TotalSelected:** 20 active collators selected per era (configurable).
* **MaxTopNominationsPerCandidate:** 300 (top delegators by stake per collator are counted).
* **MaxNominationsPerNominator:** 100. Number of collators a delegator can nominate.
* **MinCollatorStake:** 5,000 EWT (self-bond requirement).
* **MinTotalStake:** 250,000 EWT (total stake, self-bond + delegated stake, needed to be in active set).

#### Validator Onboarding Token Requirements <a href="#validator-onboarding-token-requirements" id="validator-onboarding-token-requirements"></a>

* **EWX self-stake:** ≥5,000 EWT (+ \~10 EWT gas buffer).
* **EWC:** ≥1 EWT (to sync with Tier-1 chain).
* **Ethereum:** ≥0.15 ETH (to support bridge syncing ops)
