In a significant step towards enhancing the security and transparency of its digital landscape, Vietnam has officially launched NDAChain, its national blockchain platform. Developed by the National Data Association and overseen by the Data Innovation and Exploitation Center under the Ministry of Public Security, NDAChain serves as a vital backbone for data verification within both government and private sectors.
NDAChain addresses the critical vulnerabilities of centralized data models, such as the risks of cyberattacks and limited scalability. By offering a decentralized layer of trust, the platform supports essential national systems, including e-government initiatives, finance, healthcare, logistics, and education. “Vietnam has chosen a hybrid data architecture that merges centralized and decentralized elements. NDAChain acts as a protective layer for our live data, crucial for our digital society and economy,” explained Mr. Nguyen Huy, Head of Technology at the National Data Association.
With a population of over 100 million rapidly embracing digital transformation, Vietnam generates data at an unprecedented scale. In response, the National Data Center is being established to serve as the primary repository for citizen and national information. Safeguarding this sensitive data from breaches and misuse necessitates an advanced verification system. Blockchain technology, known for its immutable records and transparency, offers a robust solution for tracking and validating data sources, especially during critical, multi-sector exchanges.
NDAChain is a Layer-1 permissioned blockchain, backed by a consortium of 49 validator nodes that includes both public institutions and private enterprises. Key players encompass the National Data Center, Ministry of Public Security, and notable corporations like SunGroup, Zalo, and Masan. Each validator node keeps a distributed ledger, ensuring transparent transaction logging and incorporating smart contracts to optimize processes. Additionally, it features identity verification tools that tie into Vietnam’s VNeID and national identity databases.
Utilizing a proof-of-authority (PoA) consensus mechanism empowered by zero-knowledge proofs (ZKP), NDAChain enhances security and privacy. The platform boasts the capacity to handle 3,600 transactions per second, resulting in low latency and high scalability for nationwide adoption. Who knew that a combination of high-tech wizardry and a strong Vietnamese spirit could tackle data challenges so elegantly?
NDAChain not only underpins e-government solutions but also fosters NDA DID, a decentralized identity system that allows individuals to verify identities in real-time during transactions, service access, or digital agreement signings. With the NDAKey app, users can authenticate identities in just seconds, drastically diminishing the risk of fraud.
The platform also powers NDATrace, Vietnam’s system for product identification, authentication, and traceability. Each product is assigned a unique identifier (UID) that complies with GS1 standards, ensuring compatibility with the EU’s EBSI framework. This interoperability enables Vietnamese businesses to seamlessly integrate into global supply chains while enhancing consumer confidence in product authenticity.
By the close of 2025, NDAChain aims for full integration with the National Data Center, extending its reach to local government entities and educational institutions by 2026. This next phase will concentrate on talent development, fostering international collaboration, and launching Layer-2 applications tailored to specific industries.
Thanks to its open and integrative design, NDAChain promises to be a catalyst for innovation, paving the way for startups and tech companies to create solutions like identity wallets and anti-counterfeiting tools.
More than 50 countries, including China, the EU, and South Korea, have rolled out national blockchain platforms. Vietnam distinguishes itself with a strategic focus on public-private partnerships, adherence to global standards, and deep integration with its national data ecosystems. NDAChain embodies Vietnam’s dedication to establishing resilient digital infrastructure and cultivating a dynamic digital economy.
