Pairwise coordination subsidies: a new quadratic funding design

Enjoyed reading all this other than the formulas.
My friend would say “Urbit fixes this”, but I would say “Diversification fixes this”:
Could the holy grail be achieved with diversification?

Example… all in one round together:
20% traditional CLR matching (whales can’t run the show)
20% pairwise-bounded quadratic matching (teams can’t team up)
20% CLR matching with Negative votes (shorts allow a free market)
10% single matching (good ol’days)
10% 3x matching (encourages donations larger than 1 Dai)
10% Randomized matching (Introduces lottery element - play lotto for your cause!)
10% Sample-vote matching (David Chaum knows what he’s talking about)

Benefits:

  • Hard to game; a gamer might go in circles
  • With the right optimization may not need identity???
  • Diversification often makes things better - the game-able characteristics of certain strategies would be highly reduced by the other strategies.

DeDivGiv = Decentralized Diversified Giving

Hi from Gitcoin.

Our resident Data Scientist, Frank Chen, ran Gitcoin Grants Round 7 data in a split test where we looked at what the diff in what results would look like if they were pairwise bonded or not. (The official results, detailed on Vitalik’s blog were pairwise bonded).

Here is the dataset, and here is a TLDR graph:

^ thanks for posting kevin

summary, using Gitcoin Grants R7 data:

  1. differences between pairwise and regular QF tell us that negative changes are more common (meaning normal QF awards generally more), but they’re all in amounts <= $100 range.
  2. the effect above takes place with grants that generally have a less contributions.
  3. large $ differences doesn’t have a definite correlation with the percent difference, but it’s still important to note that if we are in favor of removing pairwise, we want small absolute differences in $ amounts.
  4. the strongest correlation was that the greatest percent differences seem to occur with high average contribution sizes, which might suggest that regular QR vs pairwise would disproportionately affect whale donators, but this leaves average contribution sizes (total/num contributions) < 50-ish generally unchanged.
  5. it seems that the largest differences affect about 15-20% of tech grants in this example, so about 15 out of the 99 that received a CLR match.

The main objective was to figure out the tradeoff between removing pairwise matching (at least on the Gitcoin App itself) vs. gaining calculation speed to show “live” calculations.

Pairwise matching is quite intensive, since every time the mechanism is performed, we have to create permutations from every unique contributor to every other unique contributor by grant. Removing it would provide significant speed gains. However, we lose out on the natural anti-collusion checking capabilities of pairwise.

Working on a quadratic weighted staking protocol for DAOs to direct funding in a more dynamic way. Reach out if you’ve thought about this more.

working on something similar. How can I get in touch with you?

The saying goes “great minds think alike”, so I think what @Gerstep added is a major problem: we punish random people with similar tastes and therefore similar contributions across various projects, an obvious thing to happen.

This is combined with the problem that it would, I guess, be trivial for me or anyone to ask multiple third-party persons to officially make the contribution for me, if I’d seriously want to game the mechanism, hiding the correlation/pairing (?).

If these problems cannot be solved properly, I am worried whether the mechanism could ever be a big step towards solving the underlying problem with reasonable satisfaction - very happy to be proven wrong :slight_smile:
