KYC / KYB Features
Lower cost and complexity of multiple 3rd party providers, enable frictionless onboarding, shorten time-to-market and facilitate the means to comply with global KYC/KYB requirements.
Private Verification, Public Trust
Seamless identity verification, geo-fencing, and age checks, powered by Concordium's protocol-level identity. No external add-ons, fast development, and accountable features built in to protect privacy and trust, for the people and the AI agents being verified.
Trust in Protocol-Level ID Verification
Built-in identity at the protocol level replaces patchwork solutions and cuts verification overhead. With Verify with Concordium ID, stablecoin and money market fund issuers can simplify onboarding, lower legal costs, and expand distribution with confidence.
Mitigate Cyber Attacks
Reduce reliance on single point of failure. Concordium’s ID layer ensures sensitive data is never stored in one place or exposed through vulnerable smart contracts.
Increase User Adoption
Seamless identity checks and built-in privacy features reassure users, which boosts investor confidence and drives mainstream adoption among institutions and retail segments.
Fraud-Proof Credentials
Easily issue cryptographically verifiable credentials, i.e. accredited investor status or citizenship restrictions, essential for regulated tokenized funds and compliant stablecoin issuances.
Accountability with Privacy
Retain the ability to lawfully disclose identity only when required by authorities. This aligns with regulatory demands for accountability, while preserving user privacy.
Enable Global Regulatory
Readiness
Built-in ID and zero-knowledge proof (ZKP) capabilities simplify geo-fencing, age-gating, and cross-border compliance, reducing operational risks and compliance burdens for stablecoin issuers.
Zero-Knowledge Proofs at the Core
Zero-knowledge proofs (ZKPs) verify information without revealing unnecessary details. Concordium's protocol-level identity uses ZKPs to power privacy-preserving transactions across TradFi, DeFi, GameFi, payments, and agent-to-agent activity.
Geofencing for Controlled Access
Concordium’s ID and ZKP framework powers geofencing capabilities, allowing stablecoin issuers to control protocol-level tokens (PLT) access based on verified citizenship. This built-in layer supports features that streamline regulatory alignment, while ensuring frictionless user experience and global scalability.
Register and Verify AI Agents
The same protocol-level identity that verifies people also verifies agents. The Agent Registry lets developers register an AI agent with verifiable identity anchored to Concordium ID, binding it to the human or entity accountable for it. Counterparties can then check who stands behind an agent before they transact, without exposing anyone's personal data.
Enhance Permission Management
On top of Concordium’s ID layer is a tooling suite called Web3ID, which facilitates more complex issuance and permission management of verifiable credentials. This is a new W3C standard for managing digital certificates.
Zero-Knowledge Proofs on Concordium
Zero Knowledge Proofs (ZKPs) allow claims of information to be securely verified. Embedded in Concordium’s protocol layer, ZKPs enable seamless and secure identity verification, protection of payment data, and trust building without compromising personal information.
Users undergo an identity check before account activation on the network with an ID service provider, enabling various innovative use cases.
Verify Truth & Maintain Privacy
Prove a claim, event or right while ensuring user privacy and compliant payment solutions.
Reduce Compliance Costs
Streamline geofencing and KYC/AML checks without exposing excessive personal data.
Proof of Account Ownership
Provide proof of account ownership without exposing private details.
Pedersen Commitments
Concordium’s Head Architect, T.P. Pedersen pioneered a commitment protocol foundational to modern ZK applications.
ZK Implementations
Pedersen's contribution enabled lightweight ZK proofs that allow ID registration, account opening, and ID-attribute proofs from cell phones.
ZKPs Directly in Wallets
ZK-based account opening, preventing any single parties from linking ID to accounts.
Self-Sovereign Identity
All ID-attribute ZK proofs require user consent.
Accountability & Privacy
ID-attribute ZK proofs allow compliance while preserving user privacy.
Frequently Asked Questions
How do you verify identity on-chain without exposing personal data?
.svg)
Concordium uses zero-knowledge proofs, so a person or AI agent can prove an attribute such
as age, residency, or accreditation without revealing the underlying data. Identity is verified once
with a regulated provider, then proven privately as many times as needed. The proof confirms
the answer is yes while the personal details stay with the holder.
How does Concordium verify both people and AI agents?
The same protocol-level identity layer that verifies a human also verifies an AI agent, anchoring
each agent to an accountable person or business. Counterparties can confirm who stands
behind an agent before they transact, while zero-knowledge proofs keep the underlying data
private. One identity layer covers verified humans and verified agents.
What is self-sovereign or decentralised identity?
Self-sovereign identity means a person, business, or AI agent controls their own identity and
discloses only what each interaction requires. Concordium delivers this at the protocol level:
identity attributes are held off-chain, and zero-knowledge proofs let the holder prove what is
needed without handing over personal data.
How does on-chain age verification work?
A user proves they are over an age threshold using a zero-knowledge proof, so the application
receives a yes-or-no answer without ever seeing a birthdate or an identity document. The check
is anchored to a verified identity, so it is trustworthy and private at the same time. The same
approach can gate agent access to age-restricted services.
How does Concordium compare to Worldcoin?
Worldcoin focuses on proof-of-personhood through biometrics; Concordium verifies identity
through regulated providers and keeps it private with zero-knowledge proofs, with no biometric
capture. Concordium also covers AI agent identity and settlement, not just a personhood signal.
Disclosure is possible only through a lawful, multi-party process.
How does Concordium compare to Polygon ID?
Polygon ID is an identity toolkit deployed on a general-purpose chain; Concordium builds
identity into the Layer-1 protocol itself, for both humans and AI agents. Verification is enforced
at account level and cannot be bypassed, and it comes with native settlement and the Agent
Registry. Both use zero-knowledge proofs; Concordium's differentiator is protocol-level identity
plus agent accountability.
How does jurisdiction-based access (geofencing) work without tracking users?
Concordium can enforce jurisdiction rules using a zero-knowledge proof of residency, so an app confirms a user or AI agent is allowed in a region without learning their location or identity. The check is anchored to a verified identity, so it stays reliable while nothing personal is published on-chain. The same control can keep autonomous agents operating only where they are approved.
Build the Future of Agentic Settlement on Concordium
Issuing a stablecoin, or building agents that move value? Launch on infrastructure with verified identity and accountability built in, and cut smart contract risk for humans and AI agents alike.
