Really appreciate how Gregg tests contracts after every few lines of code. saves hours of debugging problems & frustration

[@ricardodias2021]

Bro thank you very much, you’re my fav blockchain developer at this point. Your videos and content are bringing so much value to everyone! This is exactly what I was looking for 💛

[@bhagatalisha]

Bro can you help me out please, I would be grateful enough, actually, I am not getting what to start in first in blockchain and then how to proceed, please help me with his tutorials

[@jebeno321]

I went through it step by step and finished! Awesome! Now I just need to understand what to do with that :D

[@PatrickAlphaC]

Dope vid Gregory!

I usually don't post comments, but this tutorial is awesome. Step by step, easy to understand. Thanks, man!

[@vittaveve1939]

Like low-key, if you were to systematically compile all of the free game he gives on KZbin, you could technically teach yourself Blockchain development…although I’d still recommend the course, it’s turned up a notch

[@dannynineone]

Good to know, thanks man. Plan to watch this course and dive into the bootcamp.

This is great, thanks. So far your examples are with test setups, which makes sense of course, but can you one time show us how to get tested code 'into production'? Thanks

[@mattbrading7862]

Anyone else get errors trying to follow along? Have replayed this over and over to make sure I'm using exact same settings, but always errors when I try to deploy. I've tried a few of these tutorials now and similar results every time... what I see doesn't match the video and no idea how to proceed... so reluctant to try the bootcamp if I can't get these basic tutorials to work?

[@mattbrading7862]

Ignore that... just saw the original post date. Thought I was watching a recent tutorial.

Do we need to dowloand Sublime and hardhat?

[@ThomasFlaum90]

i still dont understand what this returns (uint newCount) return count; does??? in my logic it creates a new variable thats an uint, with the name newCount but why doesnt it show anywhere?

[@devendrayadav1983]

1 question. you wrote transaction = await escrow.connect(buyer).finalizeSale() await transaction.wait(); "escrow.connect(buyer).finalizeSale()" call doesnt return anything. then what is 'transaction' and why to put wait() again on that transaction?

[@charanmalisetti4471]

Hey guys, Ive been trying to learn the content but whenever I try to run it on hardhat after deploying the tokens contract. it says the address is unidentified. I was getting the same error in the real estate section too. for some reason when I call the token.address, I am running into this error. I dont know if this is a hardhat version error or something. Please help me

[@jaronkenzo8582]

I love the grounded reality of this channel,its normal to see so many investors panic amid a worsening bearish market but it is also important to note that the market situation is nothing new in the crypto world. Several factors are driving negative sentiment in the stock and crypto markets right now including inflation, a shaky stock market, rising interest rates, and recession fears. As a result, bitcoin has dropped significantly from its all-time high, breaking below several key technical levels. As a crypto investor, the current situation might seem bleak. However, there are several tried and tested expert-suggested investment strategies that can help you accumulate the current crypto storm, in few weeks of implementing trading with accurate signals directly from John Woo, I have been able to accumulate over 11 btc despite the current state of the market.
