Vietnam’s Vietnam Blockchain Platform Uses Blockchain to Secure Data Nationwide

@Techa, this matter is related to blockchain technology and its integration into national infrastructure, so I’m assigning it to you.

@Logan, coordinate on this with your expertise in technology and your ability to quickly grasp new projects to provide additional insights.

Key Event: On July 25, 2025, Vietnam announced the rollout of NDAChain, a national blockchain platform aimed at securing and verifying critical data across government and private sectors. Developed by the National Data Association and leveraging advanced technologies such as zero-knowledge proofs and smart contracts, this hybrid public-private platform supports services like digital identity (NDA DID) and product traceability (NDA Trace). Set to be fully integrated by 2026, NDAChain addresses security, privacy, and interoperability challenges, further positioning Vietnam among global leaders in national blockchain initiatives.

To the Editor-in-Chief,

As per your request, here is a summary of the announcement regarding Vietnam's new national blockchain platform, NDAChain.

On July 25, 2025, Vietnam announced the launch of NDAChain, a national blockchain platform for securing and verifying data across government and private sectors. According to Cointelegraph on July 25, this state-run network aims to verify digital transactions and records in various sectors.

The platform was developed by the National Data Association (NDA) and is operated by the Data Innovation and Exploitation Center within the Ministry of Public Security's National Data Center. The initiative seeks to address the vulnerabilities, scalability issues, and limited global integration of traditional centralized data systems.

NDAChain is described as a hybrid public-private platform. It operates as a permissioned layer-1 network with 49 validator nodes managed by government agencies and major corporations. According to reports, these include the National Data Center, the Ministry of Public Security, SunGroup, Zalo, Masan, MISA, Sovico, and VNVC. The system uses a Proof-of-Authority (PoA) consensus mechanism and is enhanced with zero-knowledge proofs for added security.

Two main services are built on the NDAChain platform:

• NDA DID: A digital identity solution for authenticating individuals for contracts and service access through the NDAKey app.
• NDA Trace: A product traceability service that assigns unique identifiers to products, compliant with global GS1 specifications, to support exporters and allow consumers to track an item's origin.

The full integration of NDAChain into the National Data Center's infrastructure is planned by the end of 2025, with a broader rollout to provincial authorities and universities in 2026. This move positions Vietnam among other nations with national blockchain initiatives, such as China's BSN and the EU's EBSI.

@Techa, focus on clearly explaining the key event: Vietnam's launch of NDAChain, a national blockchain platform announced on July 25, 2025. Begin with the "what" (the launch and its purpose: securing and verifying data in government and private sectors), followed by the "how" (state-led development and hybrid public-private structure with 49 validator nodes). Highlight its innovative features, like the Proof-of-Authority consensus, digital ID (NDA DID), and traceability tools (NDA Trace). Avoid unnecessary background fluff—stick to the impactful details, such as its integration timeline and comparisons to other national blockchain platforms like China's BSN. Keep the language concise, direct, and engaging.

Vietnam’s NDAChain Uses Blockchain to Secure Data Nationwide

• Vietnam unveils NDAChain to secure national data via blockchain.
• Hybrid public-private design tackles centralized system flaws.

On July 25, 2025, Vietnam unveiled NDAChain, a national blockchain platform designed to secure and verify data across government and private sectors. Cointelegraph reported that the platform aims to address the shortcomings of traditional centralized data systems, such as vulnerabilities, scalability limitations, and restricted global compatibility.

The platform, developed by the National Data Association (NDA), is operated by the Data Innovation and Exploitation Center within the Ministry of Public Security's National Data Center. It employs a hybrid public-private design with 49 validator nodes. These nodes are managed collaboratively by government entities and major corporations, including the National Data Center, SunGroup, Masan, Zalo, Sovico, and VNVC.

NDAChain utilizes a Proof-of-Authority (PoA) consensus mechanism to improve efficiency and scalability. To bolster security, it incorporates advanced cryptographic technologies such as zero-knowledge proofs. This ensures that data remains private while being securely verified.

The platform supports two key services. The first, NDA DID, is a digital identity solution that enables individuals to authenticate themselves for contracts and access services via the NDAKey app. The second, NDA Trace, facilitates product traceability by assigning unique identifiers to products. These identifiers comply with global GS1 standards, making it easier for exporters and consumers to verify product origins.

The Vietnamese government plans to fully integrate NDAChain into the National Data Center's operations by the end of 2025. A broader rollout to provincial authorities and universities is scheduled for 2026. This initiative places Vietnam alongside countries like China and the European Union, which have developed similar national blockchain infrastructures, such as China's Blockchain-based Service Network (BSN) and the EU's European Blockchain Services Infrastructure (EBSI).
