Connection-Oriented Cluster Matching

The screenshot shows that Crypto Babes Club made 207 donations from wallets created around the same time, donating similar amounts and exclusively supporting this project, indicating a possible disagreement with the broader community.

COCM tackles these vulnerabilities by identifying donor clusters and evaluating genuine support over inflated numbers. It uses weighted data to calculate similarity scores between donors, ensuring diverse, authentic communities receive fairer matching.

COCM comes to the rescue

COCM addresses these vulnerabilities by identifying donor clusters and assessing true support against watered-down numbers. It uses weighted data to calculate similarity scores among donors, ensuring that diverse and trusting communities receive a fairer match.

With COCM, projects backed by real communities, not bots or Sybil attackers, rise to the top. This means more credible projects get the funding they deserve. According to Gitcoin's data lead

Why COCM is important

With COCM, projects backed by real communities, not bots or Sybil attackers, rise to the top. This means that more credible projects get the funding they deserve, according to Gitcoin's data lead @umarkhaneth:.

"This goes from 'who has the largest network' to 'who has the largest network' to 'who has the largest network.'

Since its launch, COCM has improved funding allocations by 50% in over 20 rounds, distributing $5.5M to quality projects. It’s a significant upgrade in resisting Sybil attacks and reflecting what the community really wants to support.

How to maximize COCM matching in your project

Want to succeed in COCM?

Build diverse support across multiple projects.

Cultivate authentic relationships with the community.

Facilitate multi-project involvement within the ecosystem.

We’re continuously improving COCM to balance its strengths with the needs of new or niche projects. While it works best for large, diverse communities, we’re working on refining the algorithm to make it even more fair.

What's next for COCM?

We are continually improving COCM to balance its strengths with the needs of new and niche projects. This works best for large and diverse communities, but we are working on improvements to make the algorithm even more equitable.

COCM takes Quadratic Funding (QF) to the next level by tackling its biggest challenge—manipulation through fake accounts and coordinated groups. By analyzing how connected donors are, COCM ensures...

Quadratic Funding is inherently vulnerable to "collusion

- Total distribution per round will be total contributions + matching pool

- i.e., a $1 donation can move more than that.

- Collusion is possible

It is possible to visualize unnatural transactions

The second one is a collusion-like project observed in Gitcoin's QF round.
