Vietnam has launched a national blockchain system to support the digital tools and services used across the country.

Known as NDAChain, the platform is designed to help verify transactions and protect sensitive data shared between people, companies, and public agencies.

The National Data Association developed the system and will be managed by the Ministry of Public Security.

NDAChain uses a combination of centralized and decentralized technology. This setup is meant to improve reliability and reduce the risk of hacking, slowdowns, and problems with connecting to other systems.

At the core of the network are 49 validator nodes. These are operated by both government bodies and major private companies, including SunGroup, Zalo, Masan, MISA, Sovico, and VNVC.

The network has two main goals. First, it will record and confirm digital transactions across areas like government services, finance, healthcare, logistics, and education.

Second, it will support a digital identity system known as NDA DID. This tool allows people and businesses to prove their identity during online interactions without exposing extra personal details.

To make identity checks quick and easy, the government has introduced the NDAKey app. The app allows users to confirm their identity within seconds.

Meanwhile, Thailand’s Securities and Exchange Commission (SEC) has recently sought public feedback on potential changes to its rules for individuals investing in crypto token sales. What did the agency say? Read the full story.
