World ID Unveils Full-Stack Proof of Human With Major Protocol Upgrade

World has released what it calls the most significant World ID protocol upgrade to date, transforming its proof-of-human system into a full-stack identity layer spanning consumer platforms, enterprise applications, and AI agents.

—

The upgrade arrives alongside the announcement of a dedicated World ID app, new integrations with Zoom and Docusign, and expanded consumer partnerships with Tinder, Razer, and live event ticketing.

With nearly 18 million people now verified through Orb devices across 160 countries, the new architecture is designed to meet production-grade requirements for businesses while remaining private and intuitive for everyday users.

What's New in the Protocol

At its core, the upgrade introduces a new architecture focused on privacy, security, and self-custody. Key technical improvements include multi-key support, key rotation, recovery mechanisms, and formal session management — features that align the protocol with enterprise security expectations.

A central concept in the new World ID is human continuity — the ability to verify that the same real, unique human is present across interactions without compromising their privacy. Unlike traditional security systems that verify devices and credentials, World ID aims to verify the actual human behind an action.

Privacy is maintained through design choices like one-time-use nullifiers, which prevent interactions from being linked or correlated, and a system architecture that ensures no personal data is exposed or stored. All verifications use zero-knowledge proofs, meaning relying parties receive only a cryptographic attestation that a real, unique human is present — nothing more.

Enterprise Integrations: Zoom, Docusign, and Outtake

The enterprise rollout includes three headline integrations that apply human continuity across different surfaces.

Zoom becomes the first communications platform to integrate World ID's Deep Face feature directly into its meetings product. The integration uses a three-way match — a cryptographically signed image from the original Orb verification, a real-time liveness selfie, and the live video frame — to confirm a participant is a real human.

Hosts can enable a Deep Face Waiting Room requiring verification before joining, or any participant can request an on-demand check mid-call. VanEck Funds is participating in a limited beta test of the feature.

Docusign is teaming up with World to bring proof of human into its document signing trust model. Through World ID, signers can confirm they are human and not a bot, establishing a foundation for human continuity in agreement workflows — particularly as processes become more automated and agent-assisted.

Outtake Verify for Email, powered by World ID, brings human continuity to enterprise email by cryptographically signing outgoing messages with proof that a verified human pressed send. Tools for Humanity has already deployed Outtake Verify across its global workforce for sensitive outbound communications.

Consumer Platforms: Tinder, Gaming, and Live Events

On the consumer side, World ID's integration with Tinder — which began as a pilot in Japan last year — is now live globally. Orb-verified users receive a verified human badge and, for a limited time, five free Boosts in select markets including Japan and the United States.

"Partnering with World ID is a natural next step in that commitment, giving our users a powerful, privacy-preserving way to help know the person on the other end is real." — Yoel Roth, Senior Vice President of Trust & Safety at Match Group

World's partnership with Razer is establishing Razer ID, verified by World ID, as a standard for proof of human in gaming. A collaboration with Mythical Games extends that work to player-owned game economies. Reddit has also signaled it is exploring privacy-first proof-of-human options, including World ID, for accounts flagged as automated.

For live events, World introduced Concert Kit, a tool that lets artists reserve tickets for verified humans. The feature launches during the Bruno Mars World Tour featuring DJ Pee Wee (aka Anderson .Paak), where verified humans will have exclusive access to VIP suite experiences at select stops.

The World ID App and AI Agent Support

The protocol upgrade also introduces the World ID app, launching first as a public beta. The app serves as a dedicated hub for managing proof of human across the internet — users can verify with platforms, manage authenticators, store credentials, and control how their World ID is used. The underlying World ID SDK is being open-sourced, enabling any app to function as a World ID authenticator.

For AI agents, the new World ID lays protocol-level groundwork for human-backed AI. Combined with AgentKit, the infrastructure enables verified humans to stand behind AI agents acting on their behalf — a capability World describes as increasingly critical as agentic AI scales.

What This Means Going Forward

The protocol components are or will be open source and permissively licensed. World is encouraging developers, researchers, and builders to review the proposed specs and provide feedback. Businesses interested in integrating World ID can explore the documentation at docs.world.org.

With integrations spanning video conferencing, document signing, email, dating, gaming, and live events, World ID is positioning proof of human as a foundational primitive across both consumer and enterprise stacks — one that operates alongside zero trust, endpoint detection, and threat intelligence in modern security architectures.
