Vietnam Launches State-Managed NDAChain Blockchain to Secure Data and Modernize Governance

Vietnam has launched NDAChain, a state-managed blockchain platform designed to secure national data and advance digital governance across critical sectors. Developed by the National Data Association and operated by the Ministry of Public Security, the platform employs a hybrid model blending centralized oversight with decentralized features. Operational since July 2025, NDAChain aims to support applications in finance, logistics, public services, and education. The system relies on 49 validator nodes managed jointly by state institutions and private partners, including SunGroup, Zalo, and Masan [1].

The platform leverages a Proof-of-Authority (PoA) consensus mechanism, enhanced with zero-knowledge proofs to ensure privacy. It introduces NDA DID, a digital identity verification tool that enables rapid identity checks and contract signing. Unlike traditional public blockchains, NDAChain operates as a permissioned network, allowing only authorized participants to validate transactions. This approach aligns with Vietnam’s emphasis on data sovereignty and regulatory control while harnessing blockchain’s transparency and immutability [2].

The initiative reflects a strategic effort to modernize governance without compromising oversight. By centralizing authority through state-backed validator nodes, Vietnam aims to mitigate risks such as fraud and inefficiency in digital transactions. The integration of private-sector partners, including Zalo’s use of the technology for e-government services, underscores a pragmatic approach to leveraging industry expertise for national infrastructure [3].

NDAChain’s architecture highlights Vietnam’s cautious yet ambitious digital agenda. The use of zero-knowledge proofs—a cryptographic method that verifies data without exposing sensitive information—addresses privacy concerns in sectors like healthcare and finance. Meanwhile, NDA DID’s streamlined identity verification is expected to reduce bureaucratic delays, facilitating seamless digital interactions for citizens and businesses [4].

The launch of NDAChain aligns with global trends of governments adopting blockchain for public services but diverges from fully decentralized models seen in the EU or China’s digital yuan experiments. This tailored approach reflects Vietnam’s regulatory environment and its desire to maintain control in a rapidly evolving technological landscape. The platform’s success will depend on adoption rates and interoperability with existing systems, though its strategic positioning as a foundational layer for the digital economy signals a long-term commitment to technology-driven governance [1].

Vietnam’s Ministry of Public Security has emphasized NDAChain’s role in modernizing infrastructure and attracting tech investment. Its integration into e-government and education is projected to foster trust in digital services, accelerating the nation’s digital literacy and economic resilience. As the project matures, its performance could influence other countries exploring state-led blockchain initiatives [4].
