Vietnam has officially launched NDAChain, a national blockchain platform developed by the National Data Association (NDA) and operated by the Data Innovation and Exploitation Center. Designed as the backbone of Vietnam's digital ecosystem, this state-run initiative addresses critical limitations in traditional centralized systems—including cyber vulnerabilities, scalability constraints, and transparency issues—by implementing a hybrid architecture that merges centralized data storage with decentralized blockchain verification.
The platform operates as a Layer 1 permissioned blockchain using a Proof-of-Authority consensus model, supported by 49 validator nodes managed jointly by government agencies (e.g., Ministry of Public Security) and major corporations (SunGroup, VNVC, Zalo, Masan, MISA, Sovico). This public-private collaboration ensures high security while enabling 1,200–3,600 transactions per second with low latency. Advanced features include zero-knowledge proofs for privacy-preserving verification and integration with Vietnam's VNeID national identity system.
NDAChain powers decentralized applications like NDA DID for identity authentication and NDATrace for supply-chain transparency, aligning with EU EBSI standards to facilitate international trade. Deployment spans critical sectors: e-government services, finance, healthcare, logistics, and education. The roadmap targets full integration into Vietnam's National Data Center by end-2025, expansion to local governments and schools by 2026, and future Layer 2 solutions with global compliance (GDPR/W3C DID).
Positioning Vietnam among 50+ nations adopting national blockchains, this initiative aims to establish digital sovereignty while fostering private-sector innovation through open technical standards.
