How It Works: A Simple 4-Step Process
We've simplified the complexity of blockchain into a straightforward, powerful workflow that benefits everyone from the issuing institution to the global employer.
1. Issue & Anchor
Your institution issues a credential (diploma, certificate, badge). A cryptographic hash of this credential, not the private data itself, is anchored to the blockchain, creating a permanent, tamper-proof timestamp and proof of existence.
2. Store in Wallet
The verifiable credential is sent directly to the learner's secure digital wallet. They, and only they, have full ownership and control over this digital asset, just like a physical diploma.
3. Share with a Click
The learner can share their credential with anyone (employers, other universities) by sending a secure link or showing a QR code. They grant permission for a specific party to view their achievement.
4. Verify Instantly
The verifier clicks the link or scans the code. Our system instantly checks the credential's signature against the immutable record on the blockchain and confirms its authenticity in seconds. No calls, no emails, no delays.
Technology Stack & Tools
We build robust, secure, and scalable solutions using a curated stack of proven blockchain technologies and enterprise-grade tools.
Real-World Success Stories
See how we've helped organizations like yours leverage blockchain to solve critical credentialing challenges.
Client Overview
A leading international university with over 30,000 students was struggling with the high administrative cost and slow turnaround time of verifying diploma requests from employers and other institutions. They were also concerned about the rising sophistication of counterfeit diplomas damaging their brand reputation.
"The manual verification process was a bottleneck for our registrar's office and a point of frustration for our alumni. We needed a solution that reflected our status as a forward-thinking institution."
- Jacob Garrett, University Registrar
The Challenge
- An average verification time of 5-7 business days.
- High operational costs tied to manual record-checking and correspondence.
- Inability to provide alumni with a modern, portable proof of their achievement.
- Increasing instances of fraudulent claims using high-quality fake documents.
Our Solution
We developed and deployed a comprehensive digital diploma platform on the Ethereum blockchain:
- Created a one-click issuance process integrated directly with their Student Information System (SIS).
- Provided each graduate with a secure, university-branded digital wallet to receive and manage their diploma.
- Built a public, user-friendly verification portal for employers to confirm diploma authenticity instantly via a QR code.
- Migrated five years of alumni records to the new system, allowing past graduates to claim their digital diplomas.
Client Overview
A national board responsible for issuing high-stakes IT security certifications needed to protect the value and integrity of its credentials. Professionals were falsely claiming certification on resumes, and the board lacked an efficient way to empower certified members to showcase their achievements digitally.
"The value of our certification is directly tied to its integrity. Blockchain gave us a way to make our credentials unfalsifiable and vastly more useful for our members."
- Ava Harrington, Director of Certifications
The Challenge
- Protecting the brand's reputation from dilution by fraudulent claims.
- Providing certified professionals with a simple way to share their status on platforms like LinkedIn.
- Reducing the administrative workload of responding to verification requests.
- Creating a clear distinction between valid and expired/revoked certifications.
Our Solution
We implemented a private blockchain solution using Hyperledger Fabric to manage the entire certification lifecycle:
- Developed a permissioned system where only the board could issue or revoke credentials.
- Created smart contracts to automatically manage certification expiry dates and renewal statuses.
- Integrated with their member portal, allowing professionals to push their verifiable credentials to their digital wallets and social profiles.
- Designed a "digital badge" system where the badge's authenticity could be checked in real-time by clicking on it.
Client Overview
A major technology firm with a global workforce needed to streamline its hiring and internal training processes. The HR department spent significant time and money on third-party services to verify the academic and professional credentials of thousands of applicants annually, causing delays in onboarding critical talent.
"We compete for top talent globally. The speed and certainty of our hiring process is a competitive advantage. Manual verification was our weakest link."
- Carter Fleming, VP of Human Resources
The Challenge
- Lengthy and expensive background check processes for new hires.
- Difficulty verifying international degrees and certifications.
- Inefficient tracking of internal training and compliance certifications for existing employees.
- Risk of hiring candidates with fraudulent or exaggerated qualifications.
Our Solution
We built an internal credential verification hub that integrated with their HRIS and connected to a consortium of academic institutions:
- Developed a secure portal for candidates to submit their verifiable credentials from participating universities.
- Integrated with their Applicant Tracking System (ATS) to automatically flag verified candidates, accelerating the hiring pipeline.
- Created an internal blockchain for issuing and tracking employee training certifications, simplifying compliance and skill management.
- Used AI to cross-reference skills listed on resumes with verified credentials, providing recruiters with a "trust score" for each candidate.

Frequently Asked Questions
The "best" platform depends on your specific needs. For public, universal verifiability and a large developer ecosystem, public chains like Ethereum or Polygon are excellent choices. For applications requiring high privacy, control, and no transaction fees, a private or consortium blockchain like Hyperledger Fabric is often more suitable. We conduct a thorough analysis of your requirements to recommend the optimal platform for your use case.
No. This is a critical point and a common misconception. To comply with privacy regulations like GDPR and FERPA, we never store Personally Identifiable Information (PII) directly on the blockchain. Instead, we store a cryptographic hash (a unique, irreversible fingerprint) of the credential. The actual credential data is stored off-chain in a secure, decentralized storage system (like IPFS) or a traditional database, accessible only to authorized parties. The blockchain is used for verification and proof of integrity, not for storing sensitive data.
We build revocation capabilities directly into the smart contracts. While the original issuance record on the blockchain is immutable, we can add a new transaction that marks a specific credential as revoked. When a verifier checks the credential, the system will query the blockchain, see the revocation status, and report that the credential is no longer valid. This process is transparent and auditable.
The timeframe can vary based on complexity. A pilot project or a Minimum Viable Product (MVP) can often be launched in 3-4 months. A full-scale, enterprise-grade platform with complex integrations might take 6-9 months. Our AI-accelerated development process and modular approach are designed to get you to market faster than traditional development cycles.
Cost is dependent on several factors: the choice of blockchain, the complexity of the features, the number of integrations, and the scale of the user base. We offer flexible engagement models, from dedicated development teams (PODs) to project-based pricing, to fit different budgets. We recommend starting with a paid discovery phase where we can provide a detailed scope and a precise cost estimate. The long-term ROI from reduced fraud and administrative savings often provides a compelling business case.
