Intract’s Proof of Humanity 101
Proof of Humanity (PoH) represents a solution to identify and verify real users in web3, providing projects with a trusted mechanism to filter out bots and sybil attacks, ensuring genuine engagement.
By implementing PoH, projects can create a more reliable and fair ecosystem for both sides. For end users, PoH offers the assurance of fair compensation, preventing their rewards from being diluted by bots and sybil clusters, especially during airdrops. Additionally, it protects them against sharp price crashes often triggered by bot-led sell-offs, preserving the value of their assets. (For a deeper dive into the fundamentals of PoH, check out our previous blog.)
What is Intract PoH & How Does It Work?
Intract’s PoH is a customisable, scalable framework for user verification built on a standardized system for sharing selective, consented data points. Instead of directly collecting data, Intract provides a structure where users can share different data points that reflect various aspects of their identity or persona.
This framework is bootstrapped with data points like social account age, CEX KYC, and airdrop participation, which are commonly used to verify humanity. Over time, any authorised entity can contribute new data points to the registry in alignment with this standard.
Level 1: Collecting Selective Data – Intract has set a standard for selective data sharing, enabling users to contribute different identity markers. These data points, such as the creation date of a Twitter account or KYC status on a CEX, can serve as indicators of a user's engagement, credibility, or longevity.
Level 2: Creating Medallions – Data points are transformed into medallions, which act as badges or credentials representing specific user attributes. For example, a user whose Twitter account is older than five years might qualify for an "Android" medallion, symbolizing a moderate level of humanity. Companies can further customise this process by defining their own medallion logic, as seen in Analog’s case, where they introduced a unique "Humanode" medallion to reflect their specific criteria. This flexibility allows projects to assign medallions that resonate with their community's standards and values.
Level 3: Compound Attestation – Combining these medallions generates an Intract PoH score, an overall indicator of the user's humanity level (e.g., 90%, 99%, or 100% human). This PoH score provides projects with a high-level assessment of the user’s credibility and trustworthiness.
The framework behind developing Intract PoH is actually an instance of a multimodal approach to identity, recognising that identity is not one-dimensional but rather composed of various facets that come forward in different contexts. For example, a person might be seen as a “Founder” in one space, a “Social Worker” in another, or a “Family Person” elsewhere. Hence, such a frame framework builds on this idea, allowing projects to capture different aspects of a user’s persona through diverse data points.
By setting up a foundation with PoH, Intract opens up possibilities for creating additional "Proof of X" attestations, like Proof of Quality Social Influence, Proof of Developer, or Proof of Good Credit. Each of these attestations can highlight specific traits relevant to different settings, enabling projects to engage with users in ways that are nuanced and contextually meaningful.
Intract PoH Medallions
Intract’s PoH framework is built around four levels of medallions—Android, Humanoid, Cyborg, and Human—each representing a different degree of humanity verification. These medallions act as verifiable credentials based on specific data points, coming together to create a compound humanity score, as shown in the visual guide:
Android – Represents basic level verifications. For example, a medallion could be awarded for a Discord account older than one year, signaling a foundational level of engagement.
Humanoid – Indicates a higher level of verification than Android. For instance, a user with an account on Farcaster, an invite-only social platform, might receive a Humanoid medallion.
Cyborg – Assigned for advanced verification signals. An example would be a Binance account-bound token, indicating the user has undergone KYC on a well-regarded platform.
Human – The highest level of verification, reserved for users with robust identity credentials. For example, a Human medallion could be awarded to users who have completed CoinBase KYC, establishing a high level of trust.
These medallions collectively determine a user’s humanity score—90%, 99%, or 100% human—based on different combinations, as projects can customise the scoring logic to align with their requirements. For instance, a project could prioritize social activity, giving more weight to social medallions, or require stricter KYC-based medallions for higher thresholds.
Another way to categorise these medallions is by type:
Social (e.g., Farcaster, Discord Age, Twitter activity) – Reflects the user's social presence and engagement.
Proof of Uniqueness (e.g., Humanode, Coinbase KYC, WorldCoin Verification) – Verifies the user’s identity through unique markers.
Proof of Rewards (e.g., Optimism airdrop eligibility, Linea LXP holder) – Demonstrates a history of participation and rewards in specific projects.
NFT Holder (e.g., Doodles, Azuki, Pudgy Penguins) – Confirms ownership of notable NFT collections, indicating a certain level of involvement in the NFT space.
Intract OG (Intract achievements) – Specific to Intract, these medallions reflect a user’s milestones and loyalty within the Intract ecosystem.

Key Differentiators of Intract PoH
Customisation Flexibility
Intract PoH allows projects to set their own verification criteria and customise medallion weightings, offering a tailored solution for them
Interoperability Across Ecosystems
Intract PoH is designed for seamless cross-platform and cross-chain compatibility, allowing users to port their verification across different ecosystems. This removes the need for repetitive verifications and broadens the reach for projects by supporting both web3 and web2 platforms.
Adaptable Scoring System
The PoH framework includes an adaptable scoring model where projects can prioritize or adjust medallions to reflect specific community standards. This flexibility ensures that genuine users are recognised while reducing false categorisations of humans as bots.
Cost-Effective Verification
With a minimal minting cost (further discounted if coming with a referral code), Intract PoH offers a more affordable verification solution compared to alternatives, making it accessible to a wider user base.
Enhanced Accessibility and Usability
Unlike other solutions that can be restrictive or complex (e.g., WorldCoin’s physical orb requirement, Gitcoin’s rigid crypto native criteria), Intract PoH prioritises ease of use and accessibility. It’s optimised for both crypto-native and new users, providing a straightforward, user-friendly verification experience.
Privacy-First Verification (Coming soon)
By utilizing Zero-Knowledge Proofs (ZKProofs), Intract PoH enables users to verify their humanity without revealing sensitive data. Users can confirm eligibility for airdrops, rewards, or access without exposing private information or needing KYC, supporting anonymous and secure verification.
Milestones & Achievements
In the past 30 days, over 100,000 users have verified their humanity with scores above 90%, with the average verification process taking just 5 minutes. PoH integration has successfully reduced duplicate fingerprints (a key indicator of bot activity) by 400% across campaigns, enhancing user authenticity.
Our PoH solution is live with 20+ projects, including partnerships with ecosystems like Analog, Shardeum & Kroma. Projects are already benefitting from the portability of Intract PoH, as a one-time verification now grants access to 15+ Intract quests and PoH-integrated websites. For instance, about 25% of all Analog PoH verifications were completed in one click, as users had previously verified their humanity.
Future Roadmap
Looking ahead, we plan to expand PoH integrations across additional ecosystems, including TON Blockchain, Movement Labs, and Solana, to broaden access and interoperability. We are also enhancing PoH to be fully privacy-compliant and permissionless through advanced features like zkProofs and zkTLS, ensuring that users can verify their humanity securely without compromising privacy.
Additionally, we are preparing to launch Intract Persona, a user-owned, privacy-compliant targeting infrastructure that will empower individuals with control over their data and enable more targeted engagement for projects. Stay tuned for our exciting updates as we build the fundamental rails of making the digital real truly interoperable, one identity solution at a time.
