Protecting GG22 with Passport XYZ

Passport XYZ is still playing a key role in Gitcoin Grants Round 22 (GG22) Sybil defense strategy? We are continuing the fight against Sybil attacks while ensuring that matching funds are fairly allocated.

For GG22, Gitcoin has evolved its Sybil resistance strategy with two powerful tools:

• Passport XYZ’s Model-Based Detection: Leveraging Passport XYZ's cutting-edge Sybil defense, Gitcoin is analyzing the onchain history of donors to prioritize unique individuals with proven activity across multiple chains.

• Connection-Oriented Cluster Matching (COCM): This innovative method analyzes donation patterns to detect groups of users who donate to similar sets of projects. By reducing the influence of these patterns, we can better identify and mitigate the effects of Sybil attackers and airdrop farmers.

What do you need to do to have your donation matched? Nothing! Model-Based Detection checks your address’s history in the background, and doesn’t require you to have a Passport. 

Although GG22 isn’t utilizing our Stamp-based verification, dozens of other projects and campaigns still rely on Passport’s Stamp-based verification to ensure their communities stay safe from Sybil attacks.

Gitcoin Stamp Clarification

Let’s chat about the Gitcoin Stamp.

We’ve been offering points for Gitcoin contributions for quite some time, and always receive questions around the time of their core rounds. 

The Gitcoin Stamp awards points to all contributors to the core round projects who are able to pass the Gitcoin Sybil defenses. You can see a full list of rounds included in the Gitcoin Stamp at the following link:

Eligible Gitcoin rounds

There is one very important detail that we want to call out:

We don’t add contributions from rounds until a few weeks after the round closes!

This delay provides Gitcoin the time they need to run their Sybil defense check so we don’t award points to bad actors.

This means that – if you make a contribution to the current round, #GG22 – your points will be awarded later in November once the round has closed and the Sybil defense checks have been completed.

No worries if you forget these details! We include all of this information within the Stamp description on the Passport app.

Product Launch: Custom Passport
