Short answer questions

What role does the user device play in this system?

The user device is the terminal where the user participates in transactions. It can be a smartphone, computer, etc. The user device sends a transaction request to the Ethereum node through the user identification website.

What is the main function of the user identification website?

The user identification website receives requests from user devices, such as registration, login, participation in ICO, etc., and converts these requests into transactions and sends them to the Ethereum node.

What role does the Ethereum state variable play in the user identification process?

The Ethereum state variable is used to record whether the user has completed the KYC process. When the user completes KYC, the Ethereum state variable will be updated to allow the user to participate in transactions that require KYC verification.

What does "Gas" mean in Ethereum transactions?

Gas is the unit used to pay transaction fees in the Ethereum network. Each transaction consumes a certain amount of Gas. The price of Gas is set by the user. The higher the Gas price, the faster the transaction.

How does the system ensure that only users who have completed KYC can participate in a specific transaction?

The system verifies whether the user has completed KYC through smart contracts. Only when the user's Ethereum state variable shows that he has completed KYC, the smart contract will allow him to participate in transactions that require KYC verification.

In this system, how can users prove that they have completed the KYC process?

Users need to complete the KYC process on the user identification website, such as submitting identity documents. The user identification website will record the user's KYC information in the Ethereum state variable.

What are the advantages of this system compared with the traditional KYC process?

The system is based on blockchain technology and has the advantages of decentralization, transparency, and security. Users only need to complete the KYC process once to participate in multiple transactions that require KYC verification, avoiding the trouble of repeatedly submitting information.

In the example shown in Figure 3, how can users participate in the ICO of Project B?

Users need to complete the KYC process on the user identification website first, and then send a certain amount of ether to the smart contract address of Project B. The smart contract will allocate the corresponding project tokens based on the user's KYC information and the amount of ether sent.

What role does "smart contract" play in this system?

Smart contracts are program codes stored on the blockchain that can automatically execute preset logic. In this system, smart contracts are used to verify user identities, manage user balances, execute transactions, etc.

What are the possible application scenarios of this system in the future?

This system can be applied to various scenarios that require user identity verification, such as online games, financial services, e-commerce, etc. It can improve transaction efficiency, reduce fraud risks, and enhance user experience.
