Say the rewards are limited to 10+ POOL. Then if bigWhale has 10000 POOL, what’s stopping them from making 1000 wallets?
Then it’s changed to 20 POOL. bigWhale consolidates his holdings to 500 wallets.
If the per wallet reward is worth it, then there is incentive to game. It’s hard to design around that.
Eligibility based on past participation might work. But that’s not necessarily fair to new entrants.
And this can only work for so long. i.e. if a wallet has to have had 20+ POOL in the POOL pool for 6 months to be eligible, bigWhale may not get rewards right now, but he’ll set up a few dozens 20+ POOL wallets in the POOL pool right now to significantly increase his winnings 6 months from now.
A time-based solution is perhaps a step in the right direction regardless, but I don’t think it is enough.
Do you have better ideas to tackle this problem?
