1. Why does traceability need national infrastructure, not just individual solutions?

Today, many businesses have already deployed their own traceability systems to manage products, supply chains, and transparency with consumers. However, when each entity operates an independent platform, traceability data tends to become fragmented and struggles to form a shared network of trust.

The individual-solution approach typically faces three major limitations:

• Data islands: each system uses different standards, formats, and storage models, making data hard to connect, reconcile, or cross-verify among supply chain parties.

• Lack of inter-party trust: when data is recorded, stored, and managed solely by one business, partners, consumers, and regulators lack sufficient grounds to verify the integrity and reliability of that information.

• Difficulty meeting international standards: export markets increasingly require traceability data that follows common, verifiable, interoperable standards compatible with international ecosystems. A single standalone system usually struggles to meet this requirement at scale.

National blockchain infrastructure addresses this by providing a shared trust foundation layer, where traceability data is recorded under a unified standard, verifiable and interoperable among businesses, consumers, supply chain partners, and regulatory agencies.

Thanks to its immutability, transparency, and distributed verification capability, national blockchain allows traceability to move beyond being merely an internal company tool and become a shared data infrastructure for a transparent supply chain. This is also why traceability is considered one of the core applications of national blockchain.

2. NDAChain's role as the traceability infrastructure layer

In the national-blockchain traceability model, NDAChain serves as the foundational infrastructure layer - the Trust Layer, enabling supply chain data to be recorded, authenticated, and verified on a shared trusted system.

Unlike a standalone traceability application, NDAChain is not itself the end-user interface for businesses or consumers. Instead, it provides the underlying infrastructure layer on which applications like NDATrace operate, ensuring traceability data has integrity, verifiability, and interoperability across multiple parties.

NDAChain's core capabilities in traceability include:

• Immutable ledger: supply chain events from production, packaging, and transport to distribution and consumption, can be recorded on the blockchain to reduce the risk of data being altered after the fact.

• High performance: with a processing capacity of 1,200–3,600 TPS, NDAChain can handle large transaction volumes from multiple industries and multiple traceability systems operating simultaneously.

• Identity and authentication: the DID/VC Core Services layer authenticates the identities of parties recording data, from manufacturers and carriers to distributors, inspection bodies, and regulators.

• Legal compliance: NDAChain is designed to operate under Level 3 information security framework, aligned with data governance, information security, and personal data protection requirements under current regulations.

As a result, NDAChain creates a trusted foundation layer that allows traceability applications to connect, share, and verify data under a common standard. This is a key distinction between a standalone traceability system and a national-scale traceability infrastructure.

3. NDATrace: a shared traceability platform

NDATrace is a traceability platform built on the NDAChain national blockchain, enabling businesses to identify, authenticate, and track a product's entire lifecycle under a unified standard. Each product or batch is assigned a unique identifier (UID) under the GS1 standard, linked to a digital record on the blockchain from production and inspection through transport, distribution, and consumption.

Every supply chain event is recorded and verified on NDAChain, making the data verifiable, traceable, and resistant to tampering or forgery. This allows businesses to make their supply chains transparent, while consumers and regulators can easily check a product's origin, history, and verification information.

As a shared platform, NDATrace enables multiple businesses to connect to a single unified traceability infrastructure, complying with GS1 standards, improving data interoperability, and staying ready to meet export market requirements.

4. Benefits of traceability on national infrastructure

Compared with standalone traceability systems, traceability on national infrastructure offers greater benefits in data interoperability, reliability, deployment cost, and management capacity.

• Cross-industry interoperability: traceability data is recorded under a common standard, allowing supply chain parties to connect, reconcile, and cross-verify.

• Greater data trust: information recorded on national blockchain infrastructure with distributed verification is more reliable than data self-stored by individual businesses.

• Export readiness: the system is designed for compatibility with international standards such as GS1 EPCIS, GS1 Digital Link, and EBSI Trace4EU, helping businesses meet the demands of discerning markets.

• Lower deployment costs: businesses, especially small and medium enterprises, don't need to build their own blockchain infrastructure and can instead use traceability as a shared utility.

• Support for state management: regulatory agencies can trace issues quickly in cases of food safety incidents, counterfeit goods, substandard products, or data discrepancies in the supply chain.

In practice, this model can be applied across many industries, from agricultural products such as GS1-standard lychee to export goods with high traceability requirements, such as bird's nest.

5. International interoperability: bringing Vietnamese goods' traceability data to the global market

A key advantage of traceability on national infrastructure is its ability to connect with international standards. As NDATrace is built toward EBSI Trace4EU compatibility and global GS1 standards, traceability data for Vietnamese goods can be standardized to meet verification requirements in export markets.

This matters especially as international regulations increasingly tighten supply chain transparency requirements, such as the EUDR on deforestation or CBAM on carbon emissions. For product groups subject to strict traceability requirements, data on origin, product journey, growing region, certifications, and emissions must be recorded in a verifiable way.

National blockchain infrastructure acts as a bridge between domestic and international data standards, helping Vietnamese businesses reduce compliance barriers, strengthen export capacity, and avoid being left behind in the global supply chain.

6. National infrastructure and the future of transparent traceability for Vietnamese goods

National blockchain application in traceability is an important step toward building a shared trust foundation for Vietnam's supply chain. When data from many industries is recorded on a trusted, standardized, and interoperable infrastructure, product information can be transparently verified from production and circulation through distribution and consumption.

This model helps Vietnamese goods build greater credibility in both domestic and export markets, gives consumers the ability to verify product origins, and helps regulators supervise more effectively when food safety incidents, counterfeiting, or data discrepancies occur.

With NDAChain as the national blockchain infrastructure layer and NDATrace as the traceability application, Vietnam has the foundation to build a national traceability system that is transparent, trustworthy, and capable of connecting with international standards. This is an important foundation for a transparent, sustainable goods market ready to integrate into the global supply chain.

Frequently asked questions (FAQ)

What is national blockchain application in traceability?
National blockchain application in traceability is the use of national-level blockchain infrastructure as a shared trust layer to record, authenticate, and trace a product's journey in an interoperable, standardized, and verifiable way. Instead of each business building its own traceability system, which easily creates "data islands" - national blockchain infrastructure allows data to be recorded uniformly, immutably, and shared among supply chain parties. On NDAChain, the NDATrace platform brings this model to life through GS1-standard product identification.

Why does traceability need national infrastructure instead of individual solutions?
Because individual traceability solutions tend to fragment data, each business uses a different system and standard, making it hard to interconnect, verify, or meet export requirements. National blockchain infrastructure provides a shared trust layer where data is recorded immutably, in standardized form, and verifiable by multiple supply chain parties.

How do NDAChain and NDATrace differ in their roles in traceability?
NDAChain is the national blockchain infrastructure layer, serving as the Trust Layer that provides an immutable ledger, digital identity, data verification capability, and a legally compliant operating environment. NDATrace is the traceability platform built on top of NDAChain, enabling businesses to attach GS1 identifiers to products, record supply chain events, and track product lifecycles from production to consumption. In other words, NDAChain is the trust infrastructure, while NDATrace is the application that brings traceability to life on that infrastructure.

What benefits does traceability on national infrastructure offer small businesses?
Small businesses don't need to build their own blockchain and can instead access traceability as a shared utility, reducing cost and technical barriers. Data on national infrastructure, verified through public–private validation nodes, is more trustworthy than self-stored data, helping raise brand value. The infrastructure is also compatible with global traceability systems such as EBSI Trace4EU, helping products get export-ready for demanding markets.
