Vietnam has taken a big step toward locking down its government data with the launch of NDAChain, a new blockchain network that only approved participants can join.
At the same time, it adds Zero‑Knowledge Proofs to keep sensitive data private while still confirming its authenticity. Officials say the network can process between 1,200 to 3,600 transactions per second, a figure aimed at supporting fast checks in e‑government, logistics and other areas.
The new system includes two key features. NDA DID provides digital IDs that tie into Vietnam’s existing VNeID setup. Citizens will be able to verify identities online when they sign documents or access services.
NDATrace offers end‑to‑end product tracking using GS1 and EBSI Trace standards. Items get unique identifiers, which can be scanned by QR codes or RFID chips. This should help businesses prove authenticity to overseas buyers and simplify recalls if problems arise.
Digital records—like medical files or student transcripts—can be checked without exposing personal details, thanks to the added privacy tools. At the same time, the permissioned setup gives authorities more control over who joins the network.
Based on reports, full integration with the National Data Center is set for completion by December 31, 2025. After that, the focus will shift to local agencies and universities, with industry‑specific Layer 2 apps planned in 2026.
Potential applications include identity wallets, counterfeit prevention systems and digital notaries. These add‑on apps will run on top of NDAChain without changing the core network.
Vietnam’s move ties directly into its National Blockchain Strategy and the new law on the Digital Technology Industry, which recognizes digital assets as of June 2025.
