Vietnam Launches National Blockchain Database
- 

Vietnam rolled out a national blockchain database (NDAChain) in July to secure identity and public records for the digital economy.
NDAChain is a layer-1 network with 49 nodes governed by private-public partnerships. It blends decentralized and permissioned systems to protect sensitive data traditionally stored on centralized servers, according to Nguyen Huy, head of technology for Vietnam’s National Data Association.
The system forms the regulated foundation for citizens and businesses to interact with onchain platforms and internet applications, further solidifying Vietnam’s role as a crypto innovation leader in APAC.
