Interlink Network introduces a blockchain model where users must verify their unique human identity through biometric checks, aiming to limit fake accounts and strengthen governance while raising new privacy and security questions
Interlink Network is advancing a blockchain infrastructure that requires users to prove they are unique humans before participating in core network activities. The project's approach, known as Proof of Personhood, uses face scans and liveness detection to issue an InterLink ID, which then allows users to become so-called Human Nodes. This system is designed to make it more difficult and costly for attackers to create multiple fake identities-known as Sybil attacks-that can undermine governance, voting, and incentive mechanisms on public blockchains.
Unlike most blockchains where a wallet address can be freely created and used as a default identity, Interlink Network ties participation to biometric verification. According to project documentation, the process involves capturing a live facial image, running liveness and deepfake checks, and converting biometric features into an irreversible hash. This hash is then used for deduplication, with zero-knowledge proofs supporting the claim that a user is a unique human without exposing raw facial data on-chain. The project emphasizes that raw face images are not stored as public ledger entries, aiming to balance Sybil resistance with privacy concerns.
Identity, Participation, and Token Roles
The Interlink ecosystem is structured around several layers: the InterLink ID for identity, the InterLink App for user interaction, the InterLink Chain for recording and coordinating activity, and two tokens-ITLG (InterLink Genesis) and ITL (InterLink Token)-with distinct roles. ITLG is intended for governance, incentives, and in-app utility, while ITL is positioned for institutional access and ecosystem coordination. The project claims that these tokens are not interchangeable and serve different functions within the network's participation and governance models.
To become a Human Node, users must complete the biometric verification process and receive an InterLink ID. This credential can then be used to access decentralized applications (dApps), participate in governance, and interact with the network as a verified individual. The project also describes delegated participation models, where Human Nodes can combine stake and reputation to validate transactions or take part in governance, but emphasizes that a one-time face scan is not equivalent to ongoing network participation.
Sybil Resistance and Privacy Trade-Offs
Proof of Personhood is positioned as an alternative to Proof of Work (PoW) and Proof of Stake (PoS), which rely on computational power or staked capital to secure the network but do not require participants to be unique individuals. By making personhood the scarce resource, Interlink Network aims to prevent bot farms and cloned wallets from manipulating outcomes. However, the effectiveness of this approach depends on the quality of biometric verification, the robustness of liveness detection, and the privacy protections built into the system.
While Interlink Network claims to avoid storing raw biometric data on-chain, the process still involves device camera permissions, client software integrity, and decentralized storage of hashed or committed data. Risks include potential false positives or negatives in liveness checks, evolving deepfake techniques, and the possibility of device compromise or phishing attacks targeting the enrollment process. The project advises users to download the InterLink App only from official sources and warns against scams that request seed phrases or private keys during verification.
Tokenomics and Ecosystem Structure
The network's token structure separates user-facing and institutional roles. ITLG is distributed to verified Human Nodes and is used for governance voting, ecosystem incentives, and utility within Mini-Apps. ITL, on the other hand, is intended for institutions, partners, and longer-term alignment, supporting staking, access to the Human Layer, and reserve functions. Allocation details and unlock schedules are not fully disclosed in public materials, and users are encouraged to review official documentation for specifics.
Interlink Network also provides Human Auth-style SDKs, allowing external platforms to require proof of unique humanity without rebuilding the full biometric stack. This modular approach is intended to make personhood verification reusable across different applications, while keeping the InterLink ID as the core identity source. The project distinguishes between identity fraud, client compromise, chain coordination bugs, and token role confusion as separate risk surfaces within the ecosystem.
Market Context and Measurable Data
As of June 2026, Interlink Network has not published independently verified figures for active Human Nodes, total InterLink IDs issued, or circulating supply of ITLG and ITL tokens. The project's documentation describes its Sybil resistance and privacy features in detail, but adoption metrics and real-world usage remain self-reported. No major U.S. exchanges have listed ITLG or ITL for spot trading, and the network's regulatory status for U.S. users is not clearly established. Users considering participation should review the latest disclosures and be aware of regional restrictions on biometric data collection and processing.
Proof of Personhood systems like Interlink Network are part of a broader trend in blockchain infrastructure to address identity and Sybil resistance without relying solely on capital or computational resources. While these systems may improve governance and reduce manipulation by fake accounts, they introduce new privacy, security, and regulatory challenges. The effectiveness of biometric hashing and zero-knowledge proofs in protecting user data depends on implementation quality, device security, and the evolving threat landscape. Users should weigh the benefits of Sybil resistance against the risks of biometric enrollment and the limitations of privacy guarantees in decentralized environments.
