Bootstrapping Global Scale Proof of Human PoH with Self I Rene Reinsberg

Sat, May 2, 2026, 12:00 AM

In this talk, Rene Reinsberg, founder of Celo and Self, presents how Self is bootstrapping global-scale proof of human infrastructure using zero-knowledge cryptography and government-issued identity documents. He announces a partnership with Google and Tether where users can verify their unique humanity through Self, claim free stablecoins, and send them to their wallet — launching next month. The system works by NFC-scanning passports or national IDs, cryptographically verifying document authenticity through country signing certificate authorities, and generating zero-knowledge proofs without storing any user data. Rene explains how applications can then request disclosure proofs (age verification, country of origin, OFAC screening) without handling PII, making it preferable to traditional KYC. He connects this to the agentic world, citing examples like Moldbook (an agent social network acquired by Meta) and Rent a Human marketplace, arguing that proof of human becomes critical when agents need to verify human counterparties or delegate identity without exposing personal data. The system enables agents to hit verification barriers in workflows and trigger ZK proof requests back to the human, unblocking agentic commerce without sharing actual identity data with the AI. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 00:00 Introduction 00:10 Welcome and Context: From Celo to Self 00:57 Why Proof of Human Matters Now 02:32 Google and Tether Partnership Announcement 03:55 Google's Use of Self for Testnet Faucets 05:29 Vision: Social Services and UBI on Crypto Rails 06:31 Why Proof of Human Is Becoming Urgent 07:41 Government Identity Infrastructure as a Foundation 09:01 How Self Works: NFC Scanning and ZK Proofs 10:43 Why NFC Beats Traditional KYC in an AI World 11:43 Zero Knowledge: No Data Storage, No Trust Required 12:13 Disclosure Proofs: Age, Country, Sanctions Screening 13:56 Registration and SDK Integration 14:20 Proof of Human in the Agentic World 15:04 Moldbook and Agent Sybil Attacks 16:00 Rent a Human: Agents Hiring Verified Humans 17:14 Delegating Identity to Agents Without Sharing Data 18:36 Self for AI Agents: Unblocking Agentic Workflows 19:44 Resources: self.xyz and ai.self.xyz 20:09 Closing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇫🇷 *Pragma Cannes 2026* Pragma Cannes 2026 was held on April 2nd at the JW Marriott Hotel in Cannes, France and was an in-person summit for builders and leaders in the web3 ecosystem.
