Ecosystem Proposal: Biomapper for Sybil Resistance

Introduction

As Metis continues to build a scalable, decentralized, and community-driven Layer 2 network, ensuring fair participation and security against Sybil attacks is crucial. Biomapper, a privacy-preserving biometric verification solution developed by Humanode, provides a seamless and effective way to achieve this.

Biomapper enables one-human-one-account verification without storing personally identifiable information (PII). By integrating it into the Metis ecosystem, dApps, DAOs, and governance mechanisms can leverage Sybil-resistant identity verification to enhance fairness, security, and trust.

What is Biomapper?

Biomapper is a decentralized biometric verification tool that allows users to prove their uniqueness without revealing their identity. It ensures that each individual can only create one verified account across platforms, preventing bot exploitation, multiple accounts per user, and fraudulent behavior.

How Biomapper Can Benefit the Metis Ecosystem

1. Sybil-Resistant Governance for DAOs

• DAOs built on Metis can integrate Biomapper to ensure fair voting mechanisms using the One Human, One Vote principle.
• Eliminates the risk of whales creating multiple identities to manipulate governance decisions.
• Ensures that real community members have an equal say in protocol upgrades and treasury management.

2. Fair and Secure Airdrops & Incentives

• Biomapper can be used to ensure that only real users participate in airdrop campaigns, preventing bots and multi-account farming.
• This improves the efficiency and fairness of reward distribution, leading to more engaged and committed community members.

3. Sybil-Resistant dApps & GameFi Projects

• GameFi projects and decentralized applications on Metis can use Biomapper to ensure unique player identities.
• Prevents multi-account abuse in play-to-earn (P2E) ecosystems, ensuring fair rewards and sustainable economies.

4. Identity Verification for Web3 Social and Reputation Systems

• Biomapper can enable verifiable, anonymous reputation scores for Metis-based DeSoc (Decentralized Social) applications.
• Users can build trusted Web3 identities without exposing their personal data.

Technical Integration with Metis

Biomapper is cross-chain dapp and can be integrated with the Metis ecosystem through its SDK. Developers can easily add biometric verification into their dApps, smart contracts, and community tools.
