Crafted with EdrawMax, this diagram outlines a blockchain - based certificate system. A government organization initiates the process by generating certifications for event/training attendees. It first “Sets up the organization’s profile,” then employs “Smart contracts for certificate generation.” Certificates of individual users are stored on the blockchain, with hashes generated for security. The organization sends both the certificate and hash to users via email. When verifying, the individual user enters the hash. The system checks if the hash exists on the blockchain: if valid, it displays the certificate, delivering the “result of certificate verification.” This template exemplifies a secure workflow, utilizing blockchain’s immutability to ensure reliable certificate management and validation.
