Explain the difference between a single transaction block (STB) and a traditional blockchain structure.

Traditional blockchains typically pack multiple transaction records into a block, while STBs only contain a single transaction record. This design improves transaction processing efficiency and allows for more granular control over individual transactions, such as modification or deletion.

How does the micro-identifier chain (MIDC) enhance user privacy protection?

MIDC stores a user's identity information and personal data on an independent blockchain rather than on a public blockchain. This isolation limits access to sensitive information and allows users to better control how their data is shared.

Describe the structure and advantages of chained array data storage.

Chained array data storage is formed by stacking multiple MIDCs, similar to the row-column structure of a traditional database. This structure allows efficient data query and management while retaining the security and immutability of the blockchain.

Explain the application of the "zero trust" security architecture in the platform.

The platform adopts a zero trust architecture and does not trust any user or device by default, including internal networks and systems. All access requests require authentication and authorization to minimize security risks.

Describe how the platform utilizes biometric recognition technology.

The platform can use biometric recognition technology for user authentication, such as using fingerprints, facial recognition, or iris scanning to log in to an account or authorize transactions. This approach is more secure and convenient than traditional password authentication.

Explain how the platform achieves compliance with data privacy laws such as GDPR and CCPA.

The platform has a built-in data privacy compliance module that automatically applies the corresponding regulations, such as GDPR or CCPA, based on the user's geographic location. The module also provides data encryption, access control, and deletion capabilities to ensure the security and compliance of user data.

Explain how the transaction proof consensus mechanism works.

The transaction proof consensus mechanism confirms transactions by verifying the validity of the transaction without waiting for confirmation from all nodes. This approach can significantly increase the speed of transaction processing because it does not require the network to reach consensus.

Describe how the anti-poisoning module prevents chain poisoning attacks.

The anti-poisoning module uses multiple technologies to detect and block malicious data from entering the blockchain network, such as image and text analysis, malware detection, and abnormal behavior analysis. If suspicious activity is detected, the module blocks the transaction and alerts the administrator.

Explain how the platform resolves the contradiction between the immutability of blockchain data and the need to delete user data.

The platform resolves this contradiction by storing user data on MIDC and using encryption technology. When users request to delete data, the platform can delete or modify the relevant data on MIDC without affecting the integrity of the public blockchain.

Describe how the platform handles transaction disputes.

The platform provides a transaction dispute module that allows users to submit disputes and provide evidence. The module acts as a central autorità to evaluate the evidence and make a ruling on the dispute. If necessary, the module can instruct the platform to modify the relevant transaction records to reflect the dispute resolution results.
