Overview
Veridian is a digital ID app that lets you prove things about yourself online, like your age, or that you are who you say you are, without uploading a photo of your driver's license or trusting a single company with your data1. You hold the proofs on your phone and choose what to share, the way you might hand a bouncer your ID without giving them a copy. The platform was incubated inside the Cardano Foundation and now runs as an independent company with teams across the US and Europe2.
Under the hood, Veridian is built on two open standards called KERI and ACDC. KERI is a way of creating an online ID that you control yourself, with no central company holding the master record. ACDC is the matching format for the proofs you carry. Both are run as community standards through Trust Over IP at the Linux Foundation, and the crypto press has described Veridian as quantum-resistant and globally interoperable13.
Key Features
- An ID app that works like a wallet. Native apps on iPhone, Android, and the privacy-focused GrapheneOS hold your credentials on the device itself. Nothing sits in a central database an attacker could break into45.
- Share only the fact you need to. If a site needs to know you're over 18, you can prove just that, without revealing your name, your birthday, or anything else printed on your ID6.
- Keys that can recover from being compromised. Veridian's underlying tech rotates the cryptographic keys that secure your ID before they're ever exposed, which the team describes as designed with future quantum computers in mind13.
- Real regulatory use cases, not just demos. The platform plugs into Utah's state digital-ID law (SB 275), a guardianship flow that lets a verified parent vouch for a child's school account, and a drop-in age check for sites that need to follow rules like COPPA, KOSA, and the UK Online Safety Act76.
- A trusted voice in the standards community. Veridian helps maintain KERIA and SignifyTS, the reference software that runs KERI, and is part of GLEIF, the organization that verifies legal company identities worldwide8.
What to Expect
Three kinds of people meet Veridian in three different places. Everyday users download the Veridian Wallet from the App Store or Google Play and use it to hold digital proofs and present them to services when asked. It's a bit like a credit-card wallet, but for IDs and certificates instead of payment cards59.
Developers and online platforms work with Veridian through a verification tool kit and a self-hostable backend, all documented at docs.veridian.id, with test environments to try integrations end to end before going live10. The wallet source code lives openly on GitHub under the Cardano Foundation.
Governments and large organizations engage on a different track. Options include fixed-scope assessments, full implementation partnerships, or licensed reseller arrangements, usually tied to a specific regulation they need to meet7. Veridian is designed to work without any particular blockchain, but Cardano is the recommended setup when an organization wants an extra public layer of trust for important records4. Curious readers can find Veridian in the wider adastack identity category alongside related tools.
