Vietnam took a huge step towards blocking government data along with the launch of Ndachain, a novel blockchain network, which can only attach approved participants.
Built by the National Data Association and supervised by the Ministry of Innovation and Exploation Center of the Ministry of Public Security, system It will serve as the main verification layer of everything from hospital documentation to school transcription and delivery logs.
Centralized system
Based on ReportsNDACHAIN uses a hybrid model. It is based on the consensus of proof – which means that only approved nodes can confirm transactions.
At the same time, he adds evidence of zero knowledge to maintain private data, while confirming its authenticity. Officials say that the network can process from 1200 to 3600 transactions per second, and the number of speech aimed at supporting quick controls in the field of electronization, logistics and other areas.

Built -in identity and tracking tools
The novel system contains two key functions. NDA provided digital identifiers that are associated with the existing Vneid configuration in Vietnam. Citizens will be able to verify online identities when they sign documents or gain access to services.
Nattrace offers tracking of end products using GS1 and EBSI tracking standards. Items receive unique identifiers that can be scanned using QR codes or RFID systems. This should lend a hand companies prove the authenticity of foreign buyers and simplify the withdrawal if problems arise.
Layer of protection and privacy
According to Nguyen Huy, head of technology at the National Data Association, Tilt It acts as a “protective layer” for Vietnam digital infrastructure. It was designed for scaling as the data volume increases.

Digital records – such as medical files or student transcription – can be checked without disclosure of personal data, thanks to the added tools of privacy. At the same time, consent configuration gives the authorities more control over who joins the network.
Implementation plans and future plans
Based on reports, full integration with the National Data Center is set until December 31, 2025. Then focus on local agencies and universities, and the layer 2 applications specific to the industry are scheduled in 2026.
Potential applications include identity wallets, counterfeit prevention systems and digital notaries. These additional applications will work on NDACHAIN without changing the basic network.
Adaptation to the national strategy
The Vietnam movement is directly related to the National Blockchain strategy and novel law in the digital technology industry, which recognizes digital resources since June 2025.
