Accruing Node Rewards

• To accrue node rewards, a Key must participate in a challenge.

• A Challenge is created approximately once every hour. This means there will be ~720 Challenges per month.

• Each Key that participates in a challenge will receive $eHAKU network rewards on a pro rata basis according to the Estimated Network Rewards.

• By default, each Haku Key has a 1% probability of participating in a Challenge. This is known as the Bronze Tier.

• Wallets can stake $eHAKU to achieve reward tiers.

• Every Key that participates in a network challenge will receive node rewards.

• To maximize the potential of earning node rewards, it is strongly recommended that you run the Haku Chain Node 24 hours a day, 7 days a week.

• The following informational table denotes the amount of staked $eHAKU per pool required to lift the Haku Keys within that pool by a given Reward Multiplier (Reward Tier Threshold). It also denotes the associated adjustment to the baseline 1% probability for staked Haku Keys to participate in a Challenge (Reward Multiplier):

Tier	Reward Tier Threshold	Reward Multiplier
Bronze	0	1x
Silver	10,000	1.5x
Gold	100,000	2x
Platinum	500,000	3x
Diamond	5,500,000	6x
