Real-World Impact of Decentralized Identity
Client Overview
A rapidly growing digital bank was struggling with high customer drop-off rates during their lengthy and repetitive KYC process. They needed a way to streamline onboarding while maintaining the highest standards of regulatory compliance.
"Errna's team didn't just deliver a product; they delivered a strategic advantage. Our SSI-based KYC system is now our biggest differentiator in the market, building trust from the very first interaction."
- Sarah Jenkins, Chief Compliance Officer, FinTrust Bank
The Problem
The client's manual KYC process was slow, expensive, and frustrating for new users. Each new product application required a full re-verification, leading to data redundancy and a poor customer experience.
Our Solution
We developed a Self-Sovereign Identity platform allowing users to create a reusable digital identity. Key aspects of the solution included:
- Integration with trusted third-party verifiers to issue Verifiable Credentials for identity, address, and income.
- A secure mobile wallet for users to store and manage their credentials.
- An API gateway for the bank's systems to request and instantly verify credentials with user consent.
- A complete, immutable audit trail on a permissioned blockchain for regulatory reporting.
Client Overview
A multi-hospital healthcare network wanted to empower patients with control over their medical records, facilitating secure and efficient data sharing between providers, insurers, and researchers while ensuring strict HIPAA compliance.
"The ability for our patients to instantly and securely grant access to their records has transformed our care coordination. Errna built a system that is both technologically advanced and deeply human-centric."
- Dr. Mark Chen, Chief Medical Information Officer, Unity Health System
The Problem
Sharing patient records between different providers was a slow, manual process fraught with security risks and administrative bottlenecks. Patients had little visibility or control over who accessed their sensitive health information.
Our Solution
We built a blockchain-based health information exchange where each patient has a DID and a private data vault. The solution featured:
- A patient-facing application to manage consent and view an immutable log of all data access requests.
- Smart contracts to automate data sharing permissions based on patient-defined rules.
- Integration with existing Electronic Health Record (EHR) systems via secure APIs.
- Use of Zero-Knowledge Proofs to enable research queries on anonymized data without compromising patient privacy.
Client Overview
A global consortium managing the shipment of high-value industrial goods needed a foolproof way to verify the identity and certifications of all participants in their supply chain, from manufacturers to carriers and customs officials.
"Trust is everything in our business. Errna's DID solution created a 'digital passport' for every entity in our network, eliminating fraud and giving us a single source of truth we can rely on."
- David Ortiz, Head of Global Logistics, Quantum Industrial
The Problem
Fraudulent paperwork and unverified participants posed significant security and financial risks. Onboarding new partners was a slow process involving extensive manual background checks, delaying shipments.
Our Solution
We implemented a consortium blockchain where each participating organization was issued a DID and a set of Verifiable Credentials for their licenses, insurance, and compliance certifications.
- A central governance body was established to issue and revoke credentials.
- Mobile applications for field agents to instantly scan a QR code and verify a carrier's or facility's credentials.
- Smart contracts that automatically checked for valid credentials at key checkpoints in the supply chain.
- A transparent, shared ledger of all verification activities for all consortium members to see.

Frequently Asked Questions
Yes, fundamentally. Traditional systems rely on centralized databases, which are single points of failure and prime targets for hackers. A blockchain-based identity system is decentralized, meaning data is distributed across a network. It's secured by cryptography, making it tamper-proof and far more resilient to attacks. It eliminates the risk of a single massive data breach compromising millions of identities.
Self-Sovereign Identity is a model where individuals and organizations have sole ownership and control over their digital identities. Instead of relying on third-party providers (like Google or a government agency) to store and manage their identity, users hold their own data in a secure digital wallet. They can then present verifiable, trustworthy information to others without giving up control of the underlying data.
We specialize in seamless integration. Our solutions are designed to work with your current systems via APIs and custom middleware. We can connect to your existing user directories, CRM, and other enterprise applications. The goal is to enhance your security and efficiency without requiring a complete overhaul of your IT infrastructure. We often start with a pilot project to demonstrate value and ensure a smooth, phased rollout.
Think of it like this: a Decentralized Identifier (DID) is like your passport number—a unique identifier that belongs only to you. A Verifiable Credential (VC) is like the visa stamp inside your passport. It's a claim made by an issuer (like a government or university) that is cryptographically linked to your DID. For example, a university issues a VC for your degree, which you can then present to an employer to prove your qualification without the employer needing to contact the university directly.
The timeline varies depending on the complexity and scope of the project. A proof-of-concept (PoC) for a specific use case can often be developed in 8-12 weeks. A full enterprise-scale implementation with multiple integrations can take 6-12 months. Our process begins with a detailed discovery phase to define a clear roadmap and provide you with a realistic timeline and budget.
