Love how you explain blockchain technology; it's such an important topic.

The history of Bitcoin you covered was fascinating!

[@yontenjamtsho4315]

Nice video tutorials. How to make a particular admin login to the system? I don't want other users to login to the system and add candidates.

[@ot1675]

how to do this?

[@daulathussain]

you can do the changes in the smart contract where the owner of the contract will allow to add candidates

[@daulathussain]

Make sure you should download the starter file and start building the project for that if you use the letter version is going to create an issue

[@gabru2780]

Hi, You have used "Lock" in line 6 @13:41 but when I use the command {npx hardhat run scripts/deploy.js --network localhost} @48:30 it gives an error {HardhatError: HH700: Artifact for contract “Lock” not found} but when i change the "Lock" in line 6 to "Create" then it works fine and shows the expected output i.e. "Lock with 1ETH is deployed to :...." I want to know If I am doing something wrong or what please tell.

[@daulathussain]

Make sure you have to use the node version 18.12 If you use letters version is going to create a problem when you will deploy the contract Because right now, Hardhat is not compatible with the latest node version For better understanding, make sure to download the starter file and install the exact version

Hello bro , u have Instagram I'd? I gotta talk with u personally

[@anushkathakur6531]

bhaiya,I have searched through all your projects,I wanted to take your suggestion on which project as a beginner to include in my resume....As the interviewer is surely gonna ask why I chose other core NFT market projects,so found a little fabricated to answer that while blockchain's contribution in voting seemed useful,can this voter Dapp be a good one for resume?? I see you have used hardhat in this too as you commented on a chat project that it can help me use test ether....hope so this project too has no difficulty in that sense....Also bhaiya,I have an earnest request,I tried finding starter files but its not available I guess now
