Proof · How it works

Open weights & the document map

Nothing about your path is hidden in a model. The whole calculation is this page — read it, and you can reproduce every number yourself.

The critical path

Identity is a chain. Each link is what the next office asks you to bring.

Supporting evidence20%
A witness, a dated record, or community ties.
Birth certificate40%
A registered record of your birth.
Photo ID — the key40%
Opens school, work, banking, and aid.

Weights sum to 100%. Holding a birth certificate also credits the evidence stage, so the bar never exceeds 100%.

Proof ledger

Saved plans are anchored to a tamper-evident SHA-256 chain — anonymous snapshots only (document types + steps), never personal data. Below is a live re-verification of the chain.
