The Challenge
A Southeast Asian government needed to create a national digital identity system to support e-government, healthcare access, and financial inclusion. Their existing system lacked data security and was reliant on foreign cloud providers, raising concerns about data sovereignty and citizen privacy.
Building Sovereign Digital Identity Infrastructure
How MedXT enabled secure, self-managed digital identity for a Southeast Asian nation
The MedXT Solution
MedXT designed and deployed a sovereign digital identity platform, powered by Hyperledger Fabric and integrated with Decentralized Identifiers (DIDs) and smart contracts. All infrastructure was hosted locally, with data encrypted and replicated across government-controlled nodes. Citizens used the system for secure login into banking, healthcare, and public services via a mobile app or secure kiosk.
The Outcome

The solution positioned the country as a regional leader in digital identity innovation, with neighboring nations now adopting similar frameworks. The blockchain infrastructure enabled new digital economy initiatives while maintaining strict data sovereignty.
"MedXT delivered more than a technical solution—they helped us establish a national digital identity framework that balances security, privacy, and accessibility. For the first time, our citizens can access all government services through a single, secure identity that they control—with the confidence that their data never leaves our borders."
