CAIN Epistemic Quorum Gate, explained for beginners

The Quorum Gate lets an action through only when enough different AI models agree; no agreement means no.

What it is

One model can be fooled. Asking several different models and requiring agreement makes a single fooled model much less dangerous.

You send each model's verdict (ALLOW, DENY or REQUIRE_APPROVAL). The gate checks whether the required share agree and signs the result. With no verdicts at all it denies (fail-closed).

An everyday comparison

A bank vault that needs two of three managers' keys.

How it works, in 4 steps

1. Several models judge the action.
2. Their verdicts are sent to the gate.
3. Enough agreement: ALLOW. Otherwise: DENY.
4. The result is signed.
