*   **Who are you, and what is your software development background?** I’m Davide, a 29 years old Italian software developer who has already been 10 years into the code, currently working in a startup in the Industry 4.0 field but with the desire to make the shift to Web3 to help build the future of the web, the web of the people.
    
*   **Why did you want to complete this lesson?** I want to complete this lesson to put another block (we love blocks 🙂) on my foundations as a web3 developer.
    
*   **When did you complete the project?** I completed the project on the 26th of October when I deployed a new version of the contract with the soltuion on the challenge Rahat made to us.
    
*   **What technologies did you use?** We used Alchemy, Polygon, Hardhat, Metamask, Solidity, OpenZeppelin.
    
*   **What did you enjoy about the tutorial?** What I enjoyed the most was the metadata updated on-chain every time you “trained“ the NFT. That blew my mind. The fact the image can be generated and hence updated on-chain.
    
*   **How do you think you can use this technology to build useful applications in the future? What are some specific example applications?** In my opinion that could be the base structure for a game, as also Rahat said on the lesson. Other than a game use case that could be a structure for updating a single NFT on-chain over time with new data for example the traceability of a product, an avatar in the metaverse. I think Alfa Romeo did something with NFTs for the new car Tonale to trace and save data about the car, I don't know the technical decisions but that could have be done in that way.
    
*   **Who would you recommend this project to?** Basically every NFT developer should think about making their NFTs with on-chain metadata, you know, we love the chain we trust the chain 🤓.
    
*   **What is the Ethereum wallet address you would like to receive your PoK at?** 0xc85C67BFe8299f61Ae0D560844E19De9Ada05519
