Vietnam has launched NDAChain, a new blockchain network that allows only approved participants to join. The move is aimed at locking down Vietnam’s government data.
About NDAChain
The network is built by the National Data Association and managed by the Ministry of Public Security’s Data Innovation and Exploitation Center. It will serve as the primary verification layer for tasks such as supply-chain logs, school transcripts, and hospital records.
According to experts, NDAChain is based on a hybrid model, relying on a Proof-of-Authority mechanism to ensure only authorized nodes can verify transactions. It also adds Zero-Knowledge-Proofs to protect sensitive data while verifying its authenticity. According to officials, NDAChain can process between 1,200 and 3,600 transactions per second, a statistic that aims to support faster verifications in logistics, e-government, and other areas.
Two new features
The networks have two main features: NDA DID offers digital IDs that integrate with Vietnam’s current VNeID framework, allowing users to verify their IDs online when signing documents or using services. On the other hand, NDATrace provides end-to-end product tracking via GS1 and EBSI Trace standards. Items are tagged with unique identifiers that RFID chips or QR codes can scan, helping businesses prove verification to overseas procurers and ease recalls in case of problems.
Privacy layer and network protection
NDAChain works as a “protective layer” for Vietnam’s digital infrastructure, built to scale as data volume expands. Digital records can be verified without needing personal details due to the added privacy tools. The permissioned setup also offers authorities more control over people joining the network. According to reports, total integration with the National Data Center will be completed by this year. The focus will then move towards local agencies and universities, where industry-specific Layer 3 apps are planned for 2026.
According to Vietnam Briefing, "in sectors such as food, pharmaceuticals, and health supplements, where counterfeit goods remain a persistent threat, NDAChain enables end-to-end product origin authentication. By tracing a product’s whole journey from manufacturer to end-consumer, businesses can enhance brand trust, reduce legal risk, and meet rising regulatory demands for transparency."
