Gitcoin has announced that it will be making adjustments to its Stamp offering and weights for its Passport product next week. The changes aim to better protect the trust and integrity of the communities users are trying to participate in. The update is based on user feedback, product usage data, and analysis of Sybil research from around the industry. The goal is to strike a balance between ease of use for users and effectiveness for partners. The update will include more transaction activity-based Stamps and refined stamp scores. Gitcoin is still recommending a score of 20 as the optimal unique humanity score for Sybil defense, so no one needs to make adjustments to active integrations. Users can publish their Passport to Optimism and LineaBuild ahead of the changes to ensure their current score remains accessible on-chain. Gitcoin is also seeking recommendations for new Stamps that meet criteria such as strong Sybil vs human signal, low cost or free for users, easy to verify, and a strong global user base.
It’s that time again! ⚠️ We will be making adjustments to our Stamp offering and weights next week ⚠️ Our commitment is to better protect the trust and integrity of the communities you are trying to participate in. Learn more 🧵👇

Gitcoin Passport Integrates Unique Humanity Scores on Arbitrum
Gitcoin Passport has announced the integration of its Unique Humanity Scores on the Arbitrum layer 2 scaling solution. This move marks a crucial step in the evolution of decentralized identity and reputation, extending Passport's attestations to permissionless and decentralized infrastructure within the Ethereum ecosystem. By identifying humans across layer 2 networks and making that data available to developers, the ecosystem aims to become healthier and more resistant to Sybil attacks. Arbitrum, currently holding nearly 40% of the total layer 2 market share in terms of total value locked (TVL), is considered one of the most decentralized layer 2 solutions, making it a suitable platform for permissionless and decentralized access to unique humanity data. This integration is the beginning of Gitcoin Passport's plans for the Arbitrum ecosystem, with more launches expected this summer.
zkLink Announces ZKL Token Airdrop for Real Humans
zkLink, an aggregated layer 3 zkEVM rollup network, has announced an airdrop of their $ZKL token. To be eligible, users must build up a Unique Humanity Score of 20 on Gitcoin Passport, a Sybil defense and identity platform. Gitcoin Passport will collaborate with zkLink to review eligibility details and protect the airdrop using Model Based Detection to assess the likelihood of Sybil actors. Real humans will be able to claim the airdrop easily, while potential Sybil actors will need to take additional steps to prove their authenticity. This partnership aims to set a new standard for protecting airdrops by utilizing branded Sybil-defense tooling and data services to identify unique humans, ensuring tokens end up in the hands of those who will add long-term value to the ecosystem.
