Vietnam deploys national blockchain for identity and records

Key Points

1. NDAChain is a layer-1 permissioned blockchain developed by Vietnam's National Data Association (NDA) and operated by the Ministry of Public Security.

2. The blockchain will serve as a protective layer for the nation's live data and is considered critical to Vietnam's digital society and economy.

3. The network uses a Proof-of-Authority (PoA) consensus protocol enhanced with zero-knowledge proofs for security.

4. State agencies and private companies like SunGroup, Zalo, Masan, MISA, Sovico, and VNVC will operate nodes on the network.

5. The NDAKey application on NDAChain will allow users to verify identities quickly to prevent scams and facilitate digital service access.
