1.2. Ensuring data security, transparency, and trust for enterprises

NDAChain’s objectives focus on building a sovereign national digital infrastructure that ensures secure, transparent, and trustworthy data while standardizing data in line with international norms. NDAChain is not a speculative crypto project, but a government oriented blockchain designed to serve national interests and the enterprise community.

Key objectives include

• Building sovereign national digital infrastructure: Developing a national layer 1 blockchain fully owned and controlled by Vietnam, serving as the verification and data connection layer for the broader digital ecosystem.

• Leading innovation and application ecosystems: Providing an open platform for enterprises, startups, and research institutions to develop practical solutions, prioritizing finance, healthcare, education, logistics, and public services.

• Ensuring secure, transparent, and trustworthy data: Using blockchain to protect citizen and organizational data, ensuring integrity, anti tampering, and transparent traceability.

• Strengthening international cooperation and positioning: Advancing Vietnam’s position regionally and globally, attracting investment, talent, and global resources.

• Standardizing data and technology: Aligning with global standards such as W3C DID, Verifiable Credentials, and GDPR, supporting consistent governance and operations.

• Driving comprehensive digital transformation: Contributing to digital government, digital economy, and digital society, and enhancing national competitiveness.

2. Foundation for security and high performance

To fulfill its mission, NDAChain integrates advanced technologies that deliver high security, strong performance, and flexible scalability, addressing common limitations of centralized systems.

2.1. Proof of Authority for transparency, speed, and scalability

NDAChain adopts Proof of Authority, where validator nodes are selected based on verified identities and reputations. This supports accountability and governance, making it suitable for government and enterprise deployments.

Performance highlights include

• Over 1,200 TPS to meet large scale demand

• Latency under 2 seconds for real time use cases

2.2. Zero Knowledge Proof for advanced data privacy

Zero Knowledge Proof enables one party to prove a statement is true without revealing underlying data.

For enterprises, especially under stricter data protection requirements, this supports privacy by design. For example, a business can verify age eligibility without collecting date of birth, or confirm financial eligibility without exposing balances.

2.3. Compliance with W3C DID and GDPR standards

NDAChain integrates W3C DID to support interoperable decentralized identities and user controlled identity management. The platform also aligns with GDPR principles to strengthen protection of personal data.

This can help enterprises

• Build credibility with global grade privacy expectations

• Improve interoperability with international systems

• Reduce compliance risk as data regulations tighten

3. Comprehensive data protection for enterprises on NDAChain

NDAChain delivers an integrated suite focused on data protection, digital identity, and traceability across supply chains, healthcare, and human data verification.
