Vietnam has officially launched NDAChain, a national blockchain platform designed to enhance digital security across government and private services.

Operated by the Ministry of Public Security’s Data Innovation and Exploitation Centre, the initiative marks a major shift in Vietnam’s digital strategy.

Developed by the country’s National Data Association, NDAChain aims to act as a protective layer for critical national data systems, laying the groundwork for an integrated, blockchain-based digital ecosystem.

The government plans full implementation by the end of 2025, signalling an aggressive move to overhaul data infrastructure with scalable, secure solutions.

NDAChain uses a hybrid blockchain architecture that combines centralised and decentralised components to overcome limitations of conventional systems.

By introducing a decentralised trust layer, the government seeks to strengthen national cybersecurity and increase interoperability between platforms.

The infrastructure is powered by a permissioned Layer 1 blockchain that includes 49 validating nodes run by both state institutions and large private enterprises. These include well-known Vietnamese firms such as Zalo, Masan, and SunGroup.

The platform operates on a Proof of Authority (PoA) consensus model, reinforced by zero-knowledge proofs (ZKPs) to ensure transactional privacy and data integrity.

This setup helps scale the system while maintaining control and trustworthiness, making it suitable for critical sectors such as finance, healthcare, education, and logistics.

To support secure identity verification, NDAChain integrates with NDA DID, a decentralised identity solution. This allows both public and private entities to confirm counterparties in sensitive transactions, reinforcing trust in digital operations.

NDAKey, another component of the platform, is designed to detect scams and impersonation, addressing widespread concerns over fraud in Vietnam’s fast-growing digital economy.

The blockchain network has demonstrated the ability to process up to 3,600 transactions per second, enabling it to support national-scale data operations.

By combining performance with regulatory oversight, NDAChain aims to serve as the backbone for e-government services and private-sector applications alike.

The Vietnamese government has laid out a phased rollout for NDAChain. In the first phase, the platform will be integrated into key national systems, including the National Data Centre, local governments, and major universities. This is scheduled to be completed by the end of 2025.

A second phase, currently under planning, will focus on international collaboration and the development of Layer 2 applications tailored to specific industries.

These may include sector-specific blockchain services for logistics tracking, educational credential verification, or public health management.

Vietnam’s adoption of blockchain infrastructure signals a broader push towards digitisation and long-term economic modernisation. With NDAChain, the country is aligning its data systems with global standards while retaining sovereign control over critical digital assets.
