Professzionál Zrt. is the developer of Time Lock Encryption, a blockchain-based solution that enables irreversible encryption of digital content until a predefined time. This ensures that no one—including the service provider—can access the data before the set time. It's especially useful in public procurement, where trustless and transparent data handling is critical. The service is available via web, desktop, and mobile apps, with token-based access.
