What are the main vision and goals of NDAChain?
NDAChain aims to enhance security and privacy through advanced encryption technologies such as Zero-Knowledge Proofs and Proof of Authority consensus mechanism.
The platform empowers citizens to control their data through decentralized identification wallets, supports flexible scalability, and complies with international standards such as W3C DID, GDPR to ensure global connectivity.
What is NDA DID and what are the benefits of using this digital identification system?
NDA DID is a decentralized identification system built on NDAChain, allowing for secure, transparent identity verification, and data sharing according to user control rights.
Benefits include DID wallets for managing records, multi-platform integration, using smart contracts for automated processing, and proving ownership of digital assets like NFTs.
What does the core technology of NDAChain include?
NDAChain uses Permissioned Blockchain technology to tightly control validation nodes, along with the Proof of Authority consensus mechanism to enhance speed and save energy, protecting data safely with Zero-Knowledge Proofs.
The system is compatible with W3C DID, GDPR standards ensuring security and legal compliance at both national and international levels.
What is Permissioned Blockchain and why did NDAChain choose this type?
Permissioned Blockchain is a blockchain network with controlled validation nodes, thus enhancing security and performance suitable for national scale, allowing safe integration with national databases via API.
What are the advantages of Proof of Authority (PoA) in NDAChain?
PoA helps process transactions quickly (over 1,200 TPS), save energy, effectively control the network, and prevent fraud by using reputable organizations as validation nodes.
What role do Zero-Knowledge Proofs (ZKPs) play?
ZKPs allow for verification of information without revealing original data, maximizing personal privacy, suitable for verifying age, income, qualifications without disclosing sensitive data.
What international standards does NDAChain comply with?
The platform is fully compatible with W3C DID, Verifiable Credentials, GDPR standards, and data protection laws in Vietnam such as the Cybersecurity Law, ensuring user identification is widely recognized.
How does the overall architecture and security of NDAChain operate?
The NDAChain system is designed according to the Hybrid DID model, combining centralized data and controlled decentralized blockchain, ensuring a balance between central power and personal autonomy.
Including the national database, VNeID wallet, blockchain, validation nodes, API gateways, smart contracts, and service providers, creating a synchronized, secure, and transparent technology network.
What is the authentication mechanism and transaction processing on NDAChain?
Users create DID through a hash of the public key integrating authentication information, stored on the blockchain using smart contracts. Verifiable Credentials issued by competent authorities can be selectively shared and verified without revealing the original data thanks to ZKP.
What elements make up the overall security architecture?
A multi-layer security model with data encryption, ZKP protecting sensitive information, data integrity, and transparent audit capability. In addition, the network has self-healing and error prevention capabilities, with all actions signed by Private Key to ensure non-repudiation.
In what real-life cases is NDAChain applied?
NDAChain supports a variety of fields from public services, finance, cross-border transactions to healthcare, helping reduce procedures, protect personal data, and enhance the digital experience for citizens and businesses.
How is access to public services improved with NDAChain?
Citizens use DID wallets validated by biometrics, sharing selective data via ZKP, helping reduce processing time by 80-90% and keeping personal information safe.
How simple are financial transactions with NDAChain?
Borrowers provide credit certificates via ZKP, banks quickly verify, secure, increase loan approval rates, and limit the risk of application fraud.
How does NDAChain enhance cross-border interaction?
Vietnam's digital identification is recognized globally thanks to W3C DID standards, helping businesses conduct transparent transactions, save costs, and enhance credibility when expanding internationally.
How is the healthcare sector benefiting?
Patients using DID wallets share health status verification certificates via ZKP, allowing doctors to accurately verify without needing to store original records, maximizing privacy protection.
What is NDAChain's specific deployment plan?
