Who are you, and what is your software development background?

As a math teacher, I learned about blockchain and web3 by chance. I think this is a new field. There are not only many new opportunities here, but also many advanced technologies.I mainly refer to these contents to complete this course：

https://docs.alchemy.com/docs/how-to-build-a-staking-dapp

Why did you want to complete this lesson? 

I have participated in many defi projects before, but I don't know how to run them, but this course has helped me understand defi more

When did you complete the project? 

2022.11.1

What technologies did you use? 

github and gitpod

What did you enjoy about the tutorial? 

modifier withdrawalDeadlineReached( bool requireReached ) {

uint256 timeRemaining = withdrawalTimeLeft();

if( requireReached ) {

require(timeRemaining == 0, "Withdrawal period is not reached yet");

} else {

require(timeRemaining > 0, "Withdrawal period has been reached");

}

_;

}

This code helps me to answer my question about how to calculate the expiration of pledge for a defi project.

How do you think you can use this technology to build useful applications in the future? 

After learning this course, I think I can independently write a smart contract on defi. With the content of the ninth issue, I can write a contract similar to uniswap.

What are some specific example applications? 

uniswap 1inch ect

Who would you recommend this project to? 

I will recommend this course to my friends. Because blockchain is really an avant-garde technology. And projects like alchemy that can teach us to write smart contracts are really great.

What is the Ethereum wallet address you would like to receive your PoK at?
