Intract’s Proof of Humanity (PoH) is a tool built on Persona Protocol to solve a big problem in web3: proving someone is a real person without invading their privacy.
It uses Persona’s tech to set a new standard for safe, fake-proof identities in decentralized systems.
PoH uses Persona’s Data Artifacts to securely unify a user’s identities (Twitter, Discord, Ethereum wallets, etc.) into a single, private profile.
Raw data remains encrypted in the user’s Persona Repository, while PoH accesses only permissioned metadata (e.g., activity patterns, tenure).
PoH developed a proprietary context model that analyzes aggregated Data Artifacts to compute a “Humanity Score” (0-100). This model runs within Persona’s Secure Enclave Cluster, ensuring raw data is never exposed.
The score updates dynamically as new Data Artifacts are added (e.g., a user’s new Discord activity raises their score).
Users can mint their Humanity Score as a soulbound NFT. This NFT acts as a publicly queryable Context Artifact. Projects verify scores via a ZK-proof, ensuring privacy. ****
Users retain full control, deciding who can view their score and having the ability to update or hide it at any time.
For Developers: A plug-and-play identity layer. Integrate PoH’s pre-trained model via a 10-line API call or customize it using Persona’s tools.
For Users: Own and selectively share proof of humanity—no KYC, no data leaks.
For the Protocol: PoH’s model is now used by 200+ projects to filter 4M+ monthly sybil attempts, showcasing Persona’s scalability.
