Key Takeaways:
- NDAChain is Vietnam’s state-backed blockchain, integrated with national digital services and identity systems.
- The system uses Proof-of-Authority with zero-knowledge proofs and supports both decentralized ID and traceability tools.
- By 2026, NDAChain will expand to regional and educational systems and support Layer 2 app development.
Vietnam has launched NDAChain, a permissioned Layer 1 blockchain to support its national digital infrastructure, according to a press release published by NDAChain on July 25.
The platform is operated by the Data Innovation and Exploitation Center under the Ministry of Public Security and developed by the National Data Association.
Mix of Centralization and Decentralization
NDAChain is integrated with the National Data Center and designed to serve as a verification layer for government and enterprise systems.
Based on the release, it runs on a Proof-of-Authority consensus model supported by 49 validator nodes managed by public and private entities, including SunGroup, Masan, Zalo, Sovico, and VNVC. The system is enhanced with zero-knowledge proofs and can process up to 3,600 transactions per second.
“Vietnam has chosen a hybrid data architecture that blends centralized and decentralized components,” said Nguyen Huy, Head of Technology at the National Data Association. “NDAChain acts as a protective layer for the nation’s live data, critical to our digital society and economy.”
The blockchain supports a decentralized identity framework (NDA DID) and a product traceability solution (NDATrace). NDA DID enables identity verification for digital contracts and online interactions, while NDATrace assigns unique identifiers to products for authentication and cross-border tracking.
Both systems integrate with existing national ID services and comply with international standards such as GS1 and W3C DID.
Vietnam Joins Countries with National Blockchains
By the end of 2025, the platform will be deployed across provincial agencies and academic institutions. The next phase includes support for Layer 2 applications, digital service development, and international collaboration.
The launch of NDAChain places Vietnam among a growing group of governments building national blockchain infrastructure to support public services and data governance.
Projects like China’s BSN, the EU’s EBSI, and South Korea’s Klaytn reflect a global trend toward state-backed blockchain platforms designed to secure identity systems, enhance supply chain traceability, and standardize data interoperability.
Frequently Asked Questions (FAQs)
Unlike China’s BSN, which operates under strict centralization, or the EU’s EBSI focused on regulatory harmonization, Vietnam uses a hybrid model combining state and private validator nodes with integration across national systems.
These standards enable NDAChain-based systems to interface with global platforms, such as the EU’s blockchain services, facilitating digital identity verification and traceability across borders.
The deployment of NDAChain is linked to the country’s national data ecosystem strategy, with plans to support startups, Layer 2 apps, and regional implementation through 2026.
