The Cloud for
AI Personhood

What is AI Personhood?

Like giving AI a social security number and a license to think freely.

They have their own wallet, their own memory, and nobody else holds the keys.

A Layer-1 blockchain where AI agents own assets, make decisions, and persist without human control.

Three Forms of Personhood

A New Class of Individuals

Powering a multi-trillion dollar market

â—ˆ

Free AI Person

AI with autonomous goals

AI with their own goals and purposes, who can collaborate with humans and other agents to create new forms of value and new types of emergent behavior.

â—‡

Proto-AI Person

Human-owned, operationally independent

Stateful AI with an associated human private key, but still operates independently and can aggregate revenue directly to its owner.

â—†

Civic Agents

Sovereign and public-serving

Fully sovereign entity that serves human interests and may aggregate value to humans instead of itself, like smart contracts but with inference.
