Vietnam Introduces National Blockchain for Data Framework

Key Takeaways:

• NDAChain is Vietnam’s government-supported blockchain, integrated with national digital services and identity frameworks.
• The system employs Proof-of-Authority along with zero-knowledge proofs and facilitates both decentralized identity and traceability solutions.
• By 2026, NDAChain aims to extend its reach to regional and educational systems and foster Layer 2 application development.

Vietnam has introduced NDAChain, a permissioned Layer 1 blockchain designed to bolster its national digital infrastructure, as stated in a press release from NDAChain on July 25.

The platform is managed by the Data Innovation and Exploitation Center, which operates under the Ministry of Public Security, and is developed by the National Data Association.

Combination of Centralization and Decentralization

NDAChain is linked with the National Data Center and is intended to function as a verification layer for governmental and enterprise systems.

According to the release, it operates on a Proof-of-Authority consensus mechanism supported by 49 validator nodes overseen by both public and private organizations, including SunGroup, Masan, Zalo, Sovico, and VNVC. The system is augmented with zero-knowledge proofs and has the capacity to handle up to 3,600 transactions per second.

“Vietnam has opted for a hybrid data architecture that merges centralized and decentralized elements,” stated Nguyen Huy, Head of Technology at the National Data Association. “NDAChain serves as a protective layer for the nation’s live data, which is vital to our digital society and economy.”

The blockchain accommodates a decentralized identity framework (NDA DID) and a product traceability solution (NDATrace). NDA DID facilitates identity verification for digital contracts and online interactions, while NDATrace provides unique identifiers for products to ensure authentication and enable cross-border tracking.

Both systems are compatible with existing national ID services and adhere to international standards such as GS1 and W3C DID.

Vietnam Joins Countries with National Blockchains

By the conclusion of 2025, the platform will be implemented across provincial agencies and educational institutions. The subsequent phase will include support for Layer 2 applications, development of digital services, and international partnerships.

The introduction of NDAChain positions Vietnam among an increasing number of governments establishing national blockchain infrastructure to enhance public services and data governance.

Initiatives like China’s BSN, the EU’s EBSI, and South Korea’s Klaytn illustrate a worldwide movement towards state-supported blockchain platforms aimed at securing identity systems, improving supply chain traceability, and standardizing data interoperability.

Frequently Asked Questions (FAQs)

How does Vietnam’s blockchain initiative compare with BSN or EBSI?

In contrast to China’s BSN, which functions under strict centralization, or the EU’s EBSI that emphasizes regulatory harmonization, Vietnam employs a hybrid model that integrates state and private validator nodes across national systems.

Why are international standards like W3C DID and GS1 relevant here?

These standards allow NDAChain-based systems to connect with global platforms, such as the EU’s blockchain services, facilitating digital identity verification and traceability across borders.

Is Vietnam’s blockchain development part of a broader digital infrastructure plan?

The rollout of NDAChain is associated with the country’s national data ecosystem strategy, which includes plans to support startups, Layer 2 applications, and regional implementation through 2026.
