Vietnam Unveils NDAChain, Hybrid Blockchain for Vital Data

- Vietnam launches NDAChain, a blockchain platform for secure data management. - Hybrid technology blends centralized and decentralized components for scalability. Vietnam recently unveiled NDAChain, its first national blockchain platform for securing and verifying sensitive data across multiple sectors. The National Data Association (NDA) developed the platform, and the Ministry of Public Security's Data Innovation and Exploitation Center manages it. On July 25, 2025, The Korea Herald reported the launch is part of Vietnam’s broader strategy to enhance its digital infrastructure and improve the nation’s data management and security framework. This permissioned layer-1 blockchain addresses key challenges that centralized systems pose, such as cybersecurity vulnerabilities, scalability limitations, and gaps in international compatibility. Operating on a Proof-of-Authority (PoA) consensus mechanism, NDAChain enables high performance and security, processing up to 3,600 transactions per second while incorporating zero-knowledge proofs to bolster its protective capabilities. A network of 49 validator nodes—managed by public agencies and private entities including the National Data Center, SunGroup, Zalo, Masan, MISA, Sovico, and VNVC—uses smart contracts to ensure transparent and automated data management. Core Services NDAChain offers two primary services for public and private stakeholders: 1. NDA DID – This decentralized identity solution enables users to verify digital identities, access services securely, and digitally sign documents with the NDAKey application. The feature mitigates risks like fraud and identity theft. 2. NDA Trace – This product traceability tool assigns GS1-compliant identifiers to goods, allowing for transparent tracking across supply chains. It is interoperable with the EU’s EBSI Trace 4EU framework, which facilitates international trade and compliance. The government plans to fully integrate NDAChain with the National Data Center by the end of 2025. It will then implement the platform across local governments and universities in 2026. Beyond its immediate applications in e-government, finance, healthcare, and education, this blockchain initiative signifies Vietnam’s growing focus on international collaboration and digital self-reliance.
