Verifiable Trust Infrastructure
The open infrastructure for trust
The open infrastructure for trust
in the age of AI.
VTI is a community-built stack that makes trust portable, verifiable, and agent-ready — between people, AI agents, and communities, with no central authority and no trust-me-bro.

The break
AI can fake a person. AI can act as you.
AI can fake a person. AI can act as you.
The internet has no answer to either.
Generative AI can fabricate a face, a voice, a résumé, a review, or an entire online history. And as agents start to act on our behalf, nothing today can verifiably answer whose interests they serve.
Both questions are really one: trust has become the scarcest resource on the internet — and every answer before VTI asked you to trust a platform, a government, or a company instead.
VTI breaks that assumption. A credential you hold. A proof you control. A check anyone can run — offline, cross-border, cross-community.
One coherent stack
Six interlocked threads. No central authority.
Nobody else ships all six as one coherent stack — people, agents, communities, cryptographic rails, human-in-the-loop governance, and regulatory compliance.
AI Agents
Scoped agent identity that acts on your behalf — with mandates it cannot exceed.
Communities
Verifiable Trust Communities write their own membership rules and own their trust graph.
Cryptographic Rails
did:webvh, DIDComm v2, the Trust Spanning Protocol, post-quantum and ZK cryptography.
Governance
Human-in-the-loop approval, least privilege, kill-switch, and tamper-evident audit.
Compliance
Architecturally aligned with eIDAS 2.0, Utah SEDI, and China’s 2026 agent rules.
Not built by one company.
Built by a movement.
The internet’s foundational protocols — TCP/IP, HTTP, TLS — became universal because no single company owned them. VTI is built on the same principle. Affinidi is a founding maintainer, not the owner.
Actively shipping
Not vaporware. Shipped code.
Every claim on this site is anchored to shipped code or a published spec.
