Solving Sybil. Counting noses with Passports.

What is it

Tap Passport to your Phone NFC and join the global trust-chain!

Port on-boards a massive Public Key Infrastructure (PKI) provided by countries and aggregated by ICAO to a server or an EOS blockchain. Port apps upload passport signature (AA) that gets authenticated up the trust-chain to your country authority, to confirm passport you just tapped is legit and currently in your possession.

What it can do

Proove your Uniqueness

Either to the public on a blockchain,
