Vietnam’s NDAChain Goes Live: National Blockchain to Fortify Public Data Security
Vietnam just flipped the switch on its sovereign blockchain—and it’s aiming straight at government data vulnerabilities. Meet NDAChain: the country’s homegrown answer to centralized data risks, now operational as of 2025.
Why it matters: From land registries to tax records, Vietnam’s public sector is betting big on immutable ledgers to curb leaks and fraud. No more ‘lost’ files or ‘accidental’ edits—every transaction gets etched in cryptographic stone.
The cynical take: Because nothing screams ‘trust us’ like a government-built blockchain while traditional banks still can’t decide if crypto is a scam or their next revenue stream. But hey, at least the tech’s real.
Bottom line: Whether this becomes a transparency milestone or just another bureaucratic sandbox depends on one thing—actual adoption. Watch the node count.
Why Does Vietnam Need a National Blockchain?
Vietnam’s digital economy is expanding extremely fast, with more than 100 million individuals producing massive volumes of data daily. But traditional centralized systems are easy targets for cyberattacks, data leaks, and make it hard to share information smoothly between platforms.
Blockchain provides a solution by developing a secure, transparent, and tamper-proof method of storing and validating data.
How NDAChain Works
NDAChain is a permissioned Layer 1 blockchain that only allows approved users to authenticate data. The network is powered by 49 validator nodes run by businesses, including Zalo, MISA, Masan, SunGroup, and state governments.
NDAChain uses a Proof-of-Authority (PoA) system, which is faster and less energy-intensive than previous protocols such as Proof-of-Work. It further incorporates Zero-Knowledge Proofs (ZKP) for the privacy of users while continuing to verify that the data exists. With the capability of supporting up to 3,600 transactions per second, NDAChain is designed for high-volume usage in leading sectors.
Real-World Uses
One of the most significant use cases built on NDAChain is NDA DID, a digital identity solution through which citizens can securely confirm identities while undertaking online transactions or digital contract signing. It thwarts impersonation, fraud, and scams in private and public services.
Another major feature is NDATrace, a product traceability system that assigns a unique code to each item. This helps confirm whether a product is genuine and meets quality standards. NDATrace is compatible with EU regulations, making it easier for Vietnamese goods to enter global markets.
From Vietnam to the World
Vietnam is the latest to join more than 50 nations, such as BSN (China), EBSI (EU), and Klaytn (South Korea), in developing their own national blockchain platforms to enable digital governance and innovation.
NDAChain stands out for its strong public-private partnerships, adherence to global standards such as GDPR and W3C DID. It has close integration with Vietnam’s National Data Center, which ensures a secure, nationwide data infrastructure.
By the end of 2025, it will be fully integrated into the national system and expand to local governments and universities in 2026. The second phase will be training talent, international collaboration, and developing useful tools such as digital wallets and e-signatures.
Despite its strong foundation, NDAChain faces several hurdles. These include technical integration with existing systems, gaining public trust, ensuring international compatibility, and managing risks linked to volatile digital asset markets.
