The maximum amount of PoX Monthly Rewards is determined by Tier, and the final amount is determined after calculating ‘My Participation Rate and ‘My Group Participation Rate’.

The equation to calculate the final amount of PoX Monthly Rewards(XSC) is shown below.

Final amount PoX Monthly Rewards(XSC) = Maximum amount of PoX Monthly Rewards(XSC) by Tier X My Group Participation Rate(%) X My Participation Rate(%)

Guidance on Tier Determination and Maximum Rewards Amount

Tier is determined by the number of provers in my group.

My group is a group of provers who are directly and indirectly connected with you by PoX including all connected provers within 12 Levels.

_

Number of valid Prover Calculation is shown below.

※ # of Valid Provers = # of provers of the subgroup with the highest connected provers X 0 + # of provers in the subgroup with the second highest connected provers X 2 + # of provers in other subgroups (not effective since July, 2019)
