40% Reduction in Identity Fraud

60% Faster Citizen Service Delivery

25% Decrease in Administrative Costs

The Challenge

The core problem was the lack of a single, authoritative source of truth for citizen identity. This created several critical issues:

Citizens had to repeatedly provide the same information to different agencies.
High incidence of fraud, particularly in subsidy and welfare distribution.
Massive operational costs associated with manual verification and data reconciliation.
Inability to launch modern, digital-first services due to a weak identity foundation.

Our Solution

Errna designed and deployed a national Self-Sovereign Identity (SSI) platform built on a permissioned Hyperledger Fabric blockchain:

Developed a secure digital wallet for citizens to control their identity data.
Created a system for issuing Verifiable Credentials for key attributes like citizenship and age.
Integrated the platform with legacy databases from five key ministries using secure APIs.
Implemented a consent management module, allowing citizens to approve every instance of data sharing.

Case Study: State-Wide Mobile Digital Driver's License (mDDL)

Client Overview

A progressive State Department of Motor Vehicles (DMV) wanted to modernize its services and provide citizens with a more convenient and secure alternative to the physical driver's license. Their goals were to reduce the costs of producing physical cards, combat counterfeit licenses, and enable new digital verification use cases for law enforcement and commercial entities (e.g., age verification).

"The mobile driver's license project has been a landmark success. Errna's blockchain solution provided the security and privacy assurances we needed to gain public trust. The adoption rate has exceeded all our projections."

Adriana Holt
CIO, State Department of Motor Vehicles

90% Reduction in Physical Card Costs

99.9% Elimination of Counterfeit Licenses

75% Faster Roadside Verification Time

The Challenge

The DMV faced several hurdles in moving from a physical to a digital credential:

Ensuring the digital license was more secure and harder to fake than the physical one.
Protecting citizen privacy, allowing them to share only necessary information (e.g., prove they are over 21 without revealing their address).
Creating a system that could be verified offline by law enforcement in areas with no connectivity.
Gaining acceptance from citizens and businesses accustomed to physical cards.

Our Solution

We developed a comprehensive mDDL ecosystem using Verifiable Credentials (VCs):

Built a citizen-facing mobile app (iOS & Android) to serve as a secure digital wallet for the mDDL.
Created a VC issuance platform for the DMV to securely mint and deliver the digital licenses to citizen wallets.
Developed a verifier app for law enforcement and businesses to scan a QR code and instantly validate the credential's authenticity.
Implemented selective disclosure, allowing citizens to present only specific pieces of information as needed.

Case Study: A Single Digital Identity for Unified City Services

Client Overview

A major metropolitan city with over 2 million residents offered dozens of digital services, from library access and public transport to paying local taxes and applying for permits. However, each service required a separate login, leading to a frustrating and disjointed experience for residents. The city's IT department wanted to create a single, secure digital identity to unify access to all municipal services.

"Errna helped us realize our vision of a truly connected city. The unified digital identity has not only simplified life for our residents but has also given us a platform for launching innovative new smart city initiatives."

Aiden Kirby
Chief Innovation Officer, City of Metropolis

50% Increase in Citizen Satisfaction

80% Reduction in Login-Related Helpdesk Calls

30% Faster Onboarding for New City Services

The Challenge

The city's primary goal was to improve the citizen experience, which was hampered by:

"Password fatigue" from managing dozens of different accounts for city services.
Security risks associated with inconsistent password policies across different departments.
High costs for managing multiple user authentication systems.
Difficulty in getting a holistic view of a resident's interaction with the city.

Our Solution

We implemented a city-wide identity platform using Decentralized Identifiers (DIDs) and a centralized citizen portal:

Issued a unique, blockchain-anchored DID to every resident upon a one-time, robust identity verification process.
Developed a "Login with City ID" single sign-on (SSO) solution that integrated with over 20 different municipal service applications.
Built a citizen dashboard where residents could manage their permissions and see which services had accessed their data.
Used smart contracts to automate access provisioning for certain services based on verifiable attributes (e.g., proof of residency).

Frequently Asked Questions

Addressing common questions from public sector leaders about blockchain for digital identity.

Absolutely. When implemented correctly, blockchain offers a level of security that surpasses traditional centralized databases. Its core features—cryptographic hashing, decentralization, and immutability—create a tamper-evident and highly resilient system. For government use, we typically recommend permissioned blockchains (like Hyperledger Fabric), which add further layers of control, allowing only authorized entities to participate in the network. This combines the transparency of blockchain with the access control needed for sensitive government data.

We understand that governments cannot simply rip and replace decades of investment in IT infrastructure. Our approach is centered on seamless integration. We build secure API gateways and middleware that allow your new blockchain identity layer to communicate with existing databases and applications. This enables a phased adoption, where you can augment and modernize your systems without causing major disruptions to ongoing operations.

This is a critical consideration, and our solutions are designed with "Privacy by Design" principles. A common misconception is that all data goes "on-chain." In our architectures, the blockchain is used to anchor identities (DIDs) and record cryptographic proofs of transactions (e.g., proof that a credential was issued and verified). The actual personally identifiable information (PII) remains off-chain, stored securely in the citizen's digital wallet or other encrypted data stores, fully compliant with regulations like GDPR's "right to be forgotten."

Scalability is a key architectural focus. We utilize modern blockchain protocols and Layer-2 solutions designed for high throughput. For GovTech applications, permissioned blockchains offer significantly higher transaction speeds than public ones. Furthermore, since most of the heavy data processing happens off-chain, the blockchain is primarily used for verification and anchoring, which is a much less intensive task. Our solutions are designed to scale to millions of citizens and thousands of transactions per second.

The timeline and cost vary significantly based on the project's scope, such as the number of integrations required, the complexity of the use cases, and the size of the user base. A pilot project or a proof-of-concept can often be delivered in 3-6 months. A full-scale, nationwide implementation is a multi-year strategic initiative. We work closely with our government partners to define a clear roadmap with phased deliverables that align with budget cycles and deliver incremental value at each stage. We recommend starting with a paid feasibility study to provide a detailed and accurate estimate.
