Vietnam Launches NDAChain to Enhance Digital Identity and Streamline Government-Private Transactions

Vietnam has launched NDAChain, a state-operated blockchain platform designed to enhance digital identity verification and streamline transaction records across government and private sectors. The system, unveiled on July 25, 2025, was developed by the National Data Association (NDA) and managed by the Ministry of Public Security’s Data Innovation and Exploitation Center. Nguyen Huy, NDA’s technology head, emphasized that the platform would provide a "decentralized layer of trust" for critical sectors like e-government, finance, healthcare, and logistics, though he clarified that the network adopts a hybrid model blending centralized and decentralized elements [1].

The NDAChain operates as a permissioned layer-1 blockchain, utilizing 49 validator nodes operated by state agencies and private entities such as SunGroup, Zalo, and Sovico. These nodes enable a distributed ledger for transaction records, smart contracts, and identity verification linked to Vietnam’s national identity systems. The platform employs a Proof-of-Authority (PoA) consensus protocol, fortified with zero-knowledge proofs for security [1]. This architecture aims to address vulnerabilities in centralized systems, including scalability issues and susceptibility to cyberattacks, while maintaining regulatory control.

A key component of the initiative is the NDA DID decentralized identity solution, which allows instant identity verification through the NDAKey application. This tool is designed to combat fraud and identity theft by enabling secure digital transactions and contract signing. Nguyen Huy highlighted that the blockchain would serve as a "protective layer" for live data, becoming "critical" to Vietnam’s digital economy [1]. The rollout aligns with the country’s 2026 roadmap to accelerate digital infrastructure, reflecting a strategic pivot toward blockchain-based governance models.

The deployment underscores Vietnam’s evolving regulatory approach to digital assets. Previously characterized by ambiguity, the country’s stance has shifted toward structured frameworks, fostering private-sector collaboration. Partnerships with entities like Dnable, which leverages blockchain for Web3 projects, illustrate this trend [4]. Analysts note that Vietnam’s early adoption of cryptocurrency—ranking among the top five globally—positions it as a regional leader in digital innovation [2].

However, challenges remain. The success of NDAChain hinges on interoperability with existing systems and public trust in decentralized verification. Adoption may face resistance in areas with limited digital literacy or bureaucratic inertia. Additionally, while the hybrid model balances security and control, critics may question the long-term viability of a semi-centralized approach in fostering true decentralization [1].

Vietnam’s strategy contrasts with efforts in other Asian nations, such as Japan’s struggles with its Akiya crisis, where outdated registries hinder progress. By integrating AI and blockchain, Vietnam aims to create a dynamic system adaptable to future needs [5]. The initiative also aligns with broader regional trends, including Singapore’s AI-driven governance, highlighting Southeast Asia’s growing focus on technology-driven resilience [5].
