Strategic infrastructure in the National Digital Architecture Framework

According to the National Digital Architecture Framework announced on October 8, Vietnam will have a National Blockchain Platform that will act as a shared digital infrastructure, spanning from central to local levels. This is one of the key components in the basic technical foundation of the national digital architecture.

The architectural framework issued by the Ministry of Science and Technology under Decision No. 3090/QD-BKHCN, with a vision to 2035, aims to build an open, connected and effectively shared national data space, serving the digital government, digital economy and digital society, while ensuring digital sovereignty and national data security. In particular, the group of platforms providing basic, shared infrastructure services is identified as the key technical foundation layer, ensuring the overall digital national architecture operates synchronously, safely and effectively.

Along with data, identification and cybersecurity infrastructures, the national blockchain platform is included in the national shared digital infrastructure group, serving the functions of authentication, retrieval and unified data certification across the entire system.

This means that when ministries, branches and localities deploy digital architecture frameworks at all levels, the national blockchain will be the foundational infrastructure component to connect, helping all data and electronic transactions to be authenticated, interconnected and centrally verified in the national data space. Blockchain is gradually asserting its position as a strategic infrastructure of Vietnam's digital architecture, similar to the role that the Internet played in the previous era.

NDAChain - core infrastructure owned by Vietnam

NDAChain is developed by the Ministry of Public Security in coordination with the National Data Center (NDC) and the National Data Association (NDA). Currently, the platform has completed its technical infrastructure, national standards and core functions. The three-layer architecture of the system has been completed, including: Layer 1 includes the core blockchain as the data authentication and preservation platform; Layer 2 includes specialized service and blockchain platforms such as NDADID, the national data platform; Layer 3 includes civil and public service applications such as NDATrace, NDAKey.

By September 2025, NDAChain had been running a stable test with 12 validator nodes at the National Data Center and strategic partners. NDAChain ensures a processing speed of ≥1,200 transactions/second and high stability. The system has recorded more than 5 million validator transactions, an average of about 30,000 transactions per day, demonstrating its ability to operate at a national scale.

Along with that, NDAChain has announced an API/SDK set including Application Programming Interface and Software Development Kit, with open integration capabilities, allowing ministries, branches, localities and businesses to easily connect, exploit and deploy data authentication applications on the same unified infrastructure.

Mr. Huy Nguyen, Head of Technology Department of National Data Association.

Mr. Huy Nguyen, Head of Technology Department of the National Data Association, said: “Blockchain is shifting from transaction technology to the core infrastructure role of the data economy . With NDAChain, Vietnam not only masters core technology but also creates a unified authentication layer for national data, making all digital transactions, from public administration to trade, transparent and verifiable.”

A trusted platform for Vietnam's data economy

More than just technology, NDAChain is considered the trusted foundation of Vietnam's data economy - where all data, transactions and digital assets are authenticated, traced and guaranteed in a unified manner. The digital identification-authentication-traceability-certification mechanisms deployed on this platform will become the basis for digital asset applications, open data, transparent public services and trusted commerce.

From NDATrace in traceability of goods, NDAKey in digital identification, to specialized data systems such as education, healthcare, agriculture, logistics... are all being integrated through NDAChain and forming a data interconnection infrastructure according to the principle: "authenticate once - use many places", playing a core role in operating digital government, digital economy and digital society.

In the late 2025-2026 period, NDAChain will expand the network of validators to technology corporations, regional data centers and provinces and cities, forming a multi-regional validator network with low latency, high fault tolerance, ready to integrate with the platforms of ministries, branches and sectors. Other localities will connect via API/SDK to regional node clusters, helping to optimize costs while still ensuring data security and sovereignty.

Mr. Nguyen Phu Dung, General Director of PILA Group, the unit participating in developing application layers on NDAChain, affirmed: “The most important thing about NDAChain is the ability to standardize and authenticate data on a national scale. When every data, product or certificate is verified through the same infrastructure, we can form a national digital asset, where value is guaranteed by trust in Vietnamese technology."

Affirming Vietnam's position of technological autonomy

The inclusion of the national blockchain platform in the National Digital Architecture Framework affirms the strategic infrastructure role of blockchain in Vietnam's digital architecture, as well as the Vietnamese team's ability to master core technology.

Together with the National Data Center (NDC) and the National Digital Architecture Framework, NDAChain contributes to forming the core infrastructure for the digital transformation era in Vietnam: Data is standardized, transactions are authenticated and trust is guaranteed.

NDAChain is not just a technology platform, but a strategic step forward in Vietnam's digital autonomy journey, aiming to become the foundational infrastructure for the national data economy and digital trust by 2030.
