Applying blockchain technology to national digital infrastructure

(NLDO) - In the context of comprehensive digital transformation, data is becoming an important resource that requires protection, authentication and effective exploitation.

In response to this need, NDAChain was introduced as a blockchain platform developed under the leadership of the National Data Center, aiming to build a secure, transparent, and tamper-resistant digital infrastructure.

Simply put, NDAChain is a Layer 1 blockchain that acts as an intermediary in verifying data from the National Data Center to citizens and businesses.

Operating at Layer 1, NDAChain acts as the "backbone" linking the solution and application layers (Layer 2, Layer 3) in the national digital ecosystem.

NDAChain is designed with a four-layer structure: a network layer with processing performance of 1,200 - 3,600 transactions per second; a storage layer ensuring encryption and data immutability; an application layer with an open API for wide integration; and a security layer using zero-disclosure authentication (ZKP) technology combined with multi-layered identification.

This platform is also built to be compatible with international standards such as W3C DID, Verifiable Credentials, and GDPR, aiming for cross-border connectivity and interoperability with the global ecosystem.

NDAChain is expected to have high applicability in many fields. In the food, pharmaceutical, and health product industries, the platform can help verify origin and monitor the supply chain, supporting businesses in combating counterfeit goods. In manufacturing and logistics, NDAChain can facilitate the automation of operational data reconciliation, reducing costs and increasing reliability when collaborating with partners. In education , finance, and insurance, the platform supports the verification of records, contracts, and customer identification, contributing to fraud reduction and enhancing the digital experience.

The development of NDAChain is set against the backdrop of Vietnam's efforts to build domestic technology infrastructure to ensure digital sovereignty and reduce dependence on foreign platforms. However, there is still little publicly available information about the scale of actual deployment and specific use cases.

Alongside NDAChain, several other domestic blockchain projects, such as HCM57 Network, are also being developed by the private sector with a similar focus on data validation and supporting digital transformation.

With a design focused on security, scalability, and integration, NDAChain is part of an effort to build a digital infrastructure platform that serves the nation's long-term goals.
