</html>How the G4T Certification System Works
- Blockchain Foundation
The G4T certification system utilizes Hyperledger Fabric blockchain technology to create an immutable, tamper-proof record of all certifications issued . This ensures that:
· Each certification receives a unique digital fingerprint (hash) that is recorded on the blockchain
· Timestamps provide precise issuance dates
· Decentralized verification prevents single points of failure
· Federated identity management enables cross-border recognition
- Certification Process for Barista Mtaani
- Evaluation: Kenya Coffee School evaluates Barista Mtaani’s curriculum, facilities, instructors, and assessment methods against international standards .
- Blockchain Recording: Upon approval, certification details are recorded on the Hyperledger Fabric blockchain, generating:
· A unique certification ID (e.g., KCS-G4T-2025-0877-BM)
· A transaction hash
· A block number
· A timestamp - Digital Badge Issuance: Barista Mtaani receives:
· A digital certification badge with QR code
· Embeddable code for their website
· Access to the verification portal - Verification Mechanism
The system enables instant verification through:
· QR Code Scanning: Direct access to verification portal
· Verification Portal: Manual entry of certification IDs at verify.kenyacoffeeschool.com
· API Integration: Direct integration with partner systems
- WordPress Integration for Barista Mtaani
To embed the certification badge on their WordPress site (https://baristamtaani.co.ke), Barista Mtaani would:
- Install the Code Embed Plugin :
· Navigate to Plugins → Add New
· Search for “Code Embed”
· Install and activate the plugin - Add Certification Badge:
· Create a new post or page
· Add a custom field named CERT_EMBED with the value containing the embed code
· Place {{CERT_EMBED}} in the content where the badge should appear - Alternative Method Using Embed Block :
· Use the Embed block in the WordPress editor
· Paste the verification URL: https://certificates.kenyacoffeeschool.com/display/KCS-G4T-2025-0877-BM
· WordPress automatically converts it to an embedded display
Benefits of the G4T System
- Trust and Credibility: Blockchain verification ensures certifications cannot be forged
- Global Recognition: Federated identity management enables international recognition
- Transparent Verification: Anyone can instantly verify certification authenticity
- Reduced Administrative Costs: Automated verification reduces manual processes
- Enhanced Reputation: Certified institutions gain prestige in the specialty coffee industry
