Web4
AI is already taking actions in the world.
We can’t prove what it did.
Web1 was access. Web2 was participation. Web3 was ownership.
Web4 is verifiable presence.
Presence = identity + trust + context + accountability
An open standard.
Proposed by Metalinxx. Owned by no one.
Anyone can build on it.
