Concordium, the PayFi-enabled blockchain, has unveiled Concordium ID, a new identity verification app built to solve a long-standing problem on the web: how to verify a user’s age without collecting and scattering their personal data.
The mobile-first application, available now for iOS and Android, uses zero-knowledge proofs (ZKPs) to let users prove they meet an age threshold (for example, 18+ or 21+) without handing over identifying information. Concordium says the design creates a single, encrypted ID that can be used across websites, dApps and services to gate age-restricted content while preserving user privacy.
Concordium CEO Boris Bohrer-Bilowitzki said: “The truth is that the web has never had a viable age verification system, resulting in piecemeal solutions that are ineffective at best and a privacy risk at worst. With Coin98 and Safle as just the first step, we’re opening the gate to a pipeline of integrations that will put privacy-preserving verification in reach of hundreds of millions of users worldwide.”
Privacy-first Age Checks, at Scale
Concordium ID aims to replace fragile, self-declared age checks and the risky approach of storing personal data on multiple platforms. Using ZKPs, users can create a Concordium account in the app and then present a cryptographic proof of age to third-party services, without exposing the underlying date of birth or identity documents.
Concordium describes the system as decentralized, secure and scalable, suitable for metering access to age-based content, services, or community features across the open internet. The company also highlights the broader utility of Concordium ID beyond simple age gating. Businesses operating in Web2 and Web3 can use the solution to meet compliance requirements without retaining customers’ raw identity data or investing in expensive, bespoke verification systems.
For Web3 projects, Concordium stresses that the ID is wallet-agnostic and offers an SDK for easy integration into dApps and protocols, enabling identity-backed PayFi features and other flows that require verified identities. At launch, Concordium ID ships with integrations into the popular wallets Coin98 and Safle, enabling a combined flow of “verify and pay” for online purchases and services.
Thanh Le, Coin98 CEO, said: “By integrating Concordium ID, we can offer privacy-preserving age checks across dApps, games, and payments to over 10 million Coin98 users from 170+ countries. It’s wallet-agnostic and developer-friendly, unlocking new categories of compliant, age-appropriate services.”
Timely Arrival Amid Rising Regulation
Concordium framed the release as particularly timely given growing regulatory attention on protecting minors from adult content, an issue attracting policy efforts in the UK, Europe and elsewhere. Governments and major tech providers have publicly struggled to implement systems that simultaneously protect minors and respect privacy; Concordium pitches its ZKP-based ID as a middle ground that preserves both safety and anonymity.
Concordium is a scalable Layer 1 blockchain that embeds an identity layer at the protocol level and leverages zero-knowledge proof technology for verified yet private interactions. Founded in 2018, the chain supports programmable tokens, PayFi features such as timed releases and compliance controls, and ID-based geofencing for cross-border transactions. Concordium positions itself as an enterprise-ready platform for stablecoins and real-world adoption that must meet regulatory frameworks.
