Gitcoin Passport 🛡️

Passport XYZ is bolstering Gitcoin Grants Round 22 (#GG22) with advanced Sybil resistance tools: - **Model-Based Detection**: Analyzes donors' onchain history across multiple chains to identify genuine users. - **Connection-Oriented Cluster Matching (COCM)**: Examines donation patterns to detect and mitigate Sybil attackers and airdrop farmers. Key points: - No additional steps required from users - Model-Based Detection works automatically in the background - Stamp-based verification still used by other projects While #GG22 doesn't use Stamp-based verification, many ecosystem projects continue to rely on it for community safety.

Shape is developing a Layer 2 (L2) solution specifically designed for developers. This new L2 platform aims to offer rewards in innovative ways, similar to what was envisioned for @pgn_eth. Key points: - Shape's L2 focuses on developer needs - Reward system inspired by @pgn_eth concepts - Partnership announced to support L2 launch Developers are encouraged to explore the available Stacks for minting on this new L2 platform. **Call to Action**: Check out the mintable Stacks and stay tuned for the L2 launch.

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, 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.

Gitcoin Passport, Gitcoin's Sybil defense and identity product, aims to help communities identify real human users. As farming tools become more advanced, Gitcoin Passport is also evolving to counter these sophisticated tools and ensure protocols interact with genuine individuals rather than Sybil attacks.

Gitcoin Passport, Gitcoin's Sybil defense and identity product, has announced a partnership with Vocdoni, a decentralized voting platform. In the context of Web3 governance, where voter identities are often anonymous or pseudonymous, the challenge of certifying that each voter represents a real person is significant. Gitcoin Passport's proof of humanity solution aims to solve this issue by protecting votes against Sybil attacks, ensuring that each vote represents a unique individual.

Gitcoin has announced an update to its Passport product, a Sybil defense and identity solution. The update includes a new training set for the zkSync Stamp verification, allowing users to prove their uniqueness as humans. Users who previously attempted to verify the zkSync Stamp are encouraged to try again. Gitcoin emphasizes that the Stamp is not activity-based, but rather focused on identifying unique human users who bring long-term value to the ecosystem. The company is working to enable on-chain Passports on zkSync for developer integration. Interested parties can learn more through direct messaging or the developer documentation provided.

According to an announcement from the official Gitcoin Passport Guild, more than 50% of the attestations on the platform are now focused on identity verification. This marks a significant milestone for Gitcoin's Sybil defense and identity product. The announcement also hints at plans to combine these identity attestations with reputational signals and broader use case adoption in the future.

Gitcoin has announced that the ETH Activity Stamp, a component of its Sybil defense and identity product Gitcoin Passport, will undergo scheduled maintenance on April 18th, 2024, from 14:20 to 15:20 UTC. During this one-hour window, the ETH Activity Stamp will be unavailable, but other services will remain unaffected.

Gitcoin Passport, Gitcoin's Sybil defense and identity product, has announced upcoming changes to its stamp scores and weights system. A new stamp for zkSync transaction activity will be introduced next week, allowing users actively building on or using zkSync to qualify for the stamp and increase their unique humanity score. While this new Layer 2 stamp will carry less weight than the Ethereum Activity stamp, it aims to make it easier for zkSync users to prove their unique humanity. Additionally, Gitcoin Passport will soon launch on-chain passport support for zkSync, similar to its existing support for Optimism and Linea. This move is expected to unlock new use cases for zkSync dApps. The changes reflect Gitcoin Passport's commitment to providing low-friction, high-trust signals to prevent egregious botting and Sybil attacks while keeping rewards in the hands of real humans.
