VAC ProtocolVERIFIABLE AUTHORITY CHAIN Start anywhere

Day one, nothing to install

Start with the approval you already give.

Forward it. The named person confirms it was really them. Everyone on the thread gets a signed receipt that anyone can check, and any change to it shows. No connectors, no IT project.

STEP 1

Forward it

CC or forward the approval to your decision address.

STEP 2

We ask first

A one-page list of who may approve what. VAC asks the right person before the action.

STEP 3

One line

Any system or AI agent asks: may this go ahead?

Inside the systems you run, once the value is proven.

Where it leads

Easy to start. Built to govern.

For the team doing the work

A quality lead or asset manager starts this week, with the approvals they already give. A register of receipts builds up on its own.

For the board

The same receipts become the evidence for governing every AI-assisted decision: who may decide, how far AI may act alone, human oversight you can prove.
