Kimlic. Blockchain-based KYC

Kimlic aims to create a decentralized KYC (Know Your Customer) solution for a world where users interact with numerous financial and Web3 services. Traditional KYC processes are often repetitive and costly and they expose sensitive data to multiple parties. The goal is to build a portable identity layer that enables users to demonstrate compliance once and then reuse their verified credentials across platforms.

The team aimed to:

• Enable secure, reusable identity verification on the blockchain.
• Reduce the need for repeated KYC checks for users and service providers.
• Preserve user privacy while complying with regulatory requirements.
• Provide businesses with compliant, scalable KYC APIs.

Kimlic sought a technology partner with expertise in high-load systems, blockchain integrations and compliance-driven platforms. Pharos Production offered extensive experience building secure, real-time Web3 infrastructure and large-scale data processing systems. As a result, they successfully delivered a production-ready KYC platform capable of serving global users and regulated businesses.

The backend is built with Elixir and Erlang to provide a highly reliable, fault-tolerant foundation for identity workflows, verification logic and API services. Event-driven communication and state changes are handled through scalable messaging patterns, while real-time processing ensures immediate, consistent updates to identity status. Deployed on AWS and Kubernetes with PostgreSQL as the primary data store, the platform is supported by a modern NextJS frontend and fully automated infrastructure managed with Terraform.

Kimlic features a modern frontend built with React and Next.js for both users and business clients. Users can manage their verified identities and consents through a secure web interface, while businesses can access dashboards and APIs to request and validate KYC proofs.

PostgreSQL stores identity metadata, verification states and audit logs at scale. All components are deployed on Kubernetes and hosted on AWS to ensure high availability, scalability and fault tolerance.

Kimlic enables users to complete identity verification once and store cryptographic proofs on the blockchain. Verified credentials can then be reused across multiple services without resending documents.

Sensitive personal data is not broadly exposed. Users share only the necessary proof with service providers while maintaining control and consent at every step.

The platform provides secure APIs for fintech, exchanges and Web3 applications to request KYC verification, validate identity status and meet regulatory obligations efficiently.

Kimlic reduces onboarding time and costs by eliminating redundant KYC processes for both users and businesses.

By integrating blockchain transparency with robust privacy measures, the platform enables businesses to demonstrate compliance and build user trust.

With its event-driven, cloud-native architecture, Kimlic efficiently processes verification events at scale without delay, laying a strong foundation for the global adoption of decentralized identity solutions.
