Staking Rewards on EWX

Reward Mechanism

• 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

• 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

• Collected fees form an additional reward pot.

• Distributed per era using the same points → stake → commission logic as growth rewards.

Validator / Collator Parameters

• 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

• 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)
