ABOUT PROOF OF ACTOR

AI does not need to disappear from digital interactions. It needs to become attributable.

Proof of Actor is building trust infrastructure for a world of humans and AI agents. We are in private development, working with early design partners.

Manifesto

The internet was designed for humans.

That assumption is ending.

AI can now speak, write, browse, negotiate, buy, apply and act on our behalf. Soon, digital services will interact constantly with humans, humans assisted by AI and autonomous agents.

The problem is not that AI participates.

The problem is that we can no longer reliably tell who is acting.

We believe every consequential digital interaction should be able to answer three questions:

Who or what is acting?
Who is in control?
Who is accountable?

Proof of Actor is building the trust infrastructure to answer them.

Mission

Build the trust infrastructure that allows humans and AI agents to interact safely, transparently and accountably across the internet.

Vision

An internet where every consequential digital action can establish who or what performed it, who authorised it and who is accountable.

North Star

Applications stop asking whether traffic "looks like a bot" and start asking for an Actor Attestation.

Category ambition

Become the trust layer applications query before relying on a digital actor.

Every layer of internet infrastructure answers one question well. This is ours.

Payments infrastructure

How does value move?

Identity providers

Who authenticated?

Network security

Can this traffic be trusted?

Proof of Actor

Who or what is actually acting?
