Vietnam launches NDAChain as national blockchain to power digital economy

Vietnam has officially launched NDAChain, a national layer 1 blockchain platform designed to protect citizens’ data, promote innovation, and support the country’s digital transformation goals, according to a Friday press release.

The system, developed by the National Data Association and operated by the Data Innovation and Exploitation Center under the Ministry of Public Security, serves as a decentralized security and verification layer for key national systems, including e-government, finance, healthcare, logistics, and education.

NDAChain processes and authenticates data before it reaches the National Data Center, helping reduce system load, enhance safety, and protect digital sovereignty. Using a Proof-of-Authority protocol enhanced by Zero-Knowledge Proofs, NDAChain is capable of processing between 1,200 and 3,600 transactions per second.

As noted in an earlier announcement, NDAChain enables instant verification, tamper-proof data, and privacy protection, while supporting real-time access and cross-sector integration. Its open architecture allows easy adoption by both enterprises and government agencies.

“NDAChain acts as a protective layer for the nation’s live data, critical to our digital society and economy,” said Mr. Nguyen Huy, Head of Technology at the National Data Association, in a statement.

NDAChain runs on a network of 49 validator nodes managed by leading government agencies and major corporations like Masan, VNG, SunGroup, VNVC, and MISA. The platform is built to meet international standards, including W3C DID and GDPR.

By the end of 2025, NDAChain will be fully integrated into the National Data Center, with expansion to local governments and universities planned for 2026. Future initiatives will focus on scaling infrastructure, international cooperation, and creating a robust ecosystem of layer 2 and layer 3 applications.

The platform is aimed at supporting the development of various digital services, including identity wallets, anti-counterfeit solutions, and digital notarization across different sectors.
