NDAChain is a key technology initiative led by the National Data Center, under the strategic direction of the Vietnam National Data Association. This is a core technology blockchain platform, identified as one of the strategic pillars deployed based on the spirit of Notice No. 171 of the Prime Minister in March 2025.
This solution is applied to a modern digital data infrastructure, as Vietnam currently operates a huge amount of data from more than 100 million people and thousands of agencies and organizations. Therefore, NDAChain is designed as an intelligent middleware layer that allows authentication, protection and recording of data transactions before they are processed at the National Data Center. This helps reduce system load, eliminate the risk of a single point of failure, while ensuring data integrity, transparency and traceability at all levels.
Unlike public blockchains, NDAChain operates on a permissioned blockchain model, where each validator node is carefully selected and monitored. The network currently has 49 validators representing ministries, sectors, and large economic groups such as Masan , VNVC, SunGroup, Sovico, VNG, Misa, etc.
NDAChain is built on an advanced core technology platform, combining the Proof-of-Authority (PoA) consensus algorithm for fast, secure and energy-saving authentication. The Zero-Knowledge Proof (ZKP) security mechanism allows information verification without revealing the original data, ensuring user privacy. Compliance with international standards such as W3C DID, Verifiable Credentials and GDPR makes NDAChain ready for cross-border integration. With a processing capacity of 3,600 transactions per second and a latency of only 1.5 seconds, the platform flexibly meets both the business needs of the State and enterprises in digital transformation.
NDAChain is not only a new technology platform, but is becoming a strategic digital infrastructure in many important fields. With its immutable properties and real-time data retrieval, NDAChain can be applied in a variety of industries. In the fields of food, pharmaceuticals, health products where businesses often face counterfeit and fake goods... And NDAChain helps authenticate the origin, monitor the entire journey of the product from the manufacturer to the consumer.
It is known that NDAChain will complete integration into the National Data Center in 2025, expanding to localities and universities from 2026. The next phase will focus on human resource training, promoting international cooperation and deploying extended layers (Layer 2) to serve multiple industries.
With its open architecture and integration promotion policy, NDAChain is not only a national technology infrastructure, but also an opportunity for technology companies, startups and private organizations to develop applications together. Therefore, NDAChain is gradually affirming its position in the global digital transformation race by putting data and technology at the center of development.
