Good luck everyone! Hope to see you in the community!
thx for your amazing work, looking forward to work with you
Hands down best tutorial I've ever done. Like not just for Ethereum development but in general amazing job I'm going to watch it twice just because
@@mrsquiggles1379 I’m so flattered!
Hey Patrick, is there a discord channel to connect with the community and discuss?
I've watched a few of your previous videos and when I saw this come up in new I couldn't wait to get stuck in. Only a few hours in and had to leave a comment - this is an awesome tutorial! So many concepts that are poorly explained elsewhere, cleared up in simple, easy to follow content - brilliant!
Couldn't agree more with the sentiment here. Clarity is key, and Forbidden Crypto Hacks book seems to provide just that. Can't wait to dive in!
Successful people don't become that way overnight. What most people see at a glance- wealth, a great career, purpose-is the result of hard work and hustle over time. I pray that anyone who reads this will be successful in life..
@@jonaskuhn8237 You're right, Investing in bitcoin now is the best thing to do especially with the current rise in the market
people are really making a lot of money from it... . .

i mean if im here, i'm trying to be that person lol
6 hours into this...and I must say I've learned more from this than any other free/paid courses I've taken.
One thing though, huge numbers like 20000000000 can be written as 20_000_000_000 in python to improve readability. 😃

If you don't mind me asking, are you a complete beginner or are you an experienced developer?

I am doing Udemy - Ethereum and Solidity The Complete Developers Guide course and in the middle found this one. Some part of the course I am currently doing is looks outdated. Can you advise?
also works in javascript!
To be a super-trader, you'll need an edge to overcome the laws of probability and the uncertainty of the marketplace. That edge comes from information flow, the ability to correct your habits in terms of the market's characteristics, and being able to learn from people who know more than you, cut losses, expand your information network, ferret out ideas, and take recommendations. You can seek more guidance from Paulson Dmitriev his guidance got me this far.
Paulson Dmitriev is one of the few traders i know that do it the right way, i have used his service on numerous occasions. I would recommend him as well.
@MR. ALEX HOWE I respect his analysis and his signals are mostly accurate and 100% active.
@Rochy I know Paulson Dmitriev, i reach-out to him long ago He's is a pro trader with accurate signals, that guy is amazing.
Starting the year joyfully after partaking in crypto December last year, never knew it was this lucrative. I'm still overwhelmed because this exceeded my expectations, I lack the skill but I earn while I learn
Great scam going here .. this comment and all folks endorsing to this comment belong to one team 😂
I can't believe that giga chads like you guys give these content for programmers FOR FREE!
Slight correction friend.. ultra giga chads
For the best teacher on earth, I don't have a single collage degree just but I always knew that I had to find the right person to teach me stuff.
For me that was you Patrick
You guys are doing such a wonderful job for the entire community...hats off to ur efforts
It is so much fun to watch this tutorial again after 6 months. Still learn a lot, thanks!
Absolutely great... I have waited for this for so long
I often don't comment but I really appreciate you guys. Thanks for this wonderful course, You guys are amazing!
This guy is amazing and can't appreciate enough about his passion to teach people.
At 3:44:35:
He forgot to install the solidity compiler first! You can do so with:
from solcx import compile_standard, install_solc
install_solc("0.6.0")
... in the deploy.py file. He corrected it on the github page. In case you got stuck here like me :)
thanks!
how can i install it? please help me I don't know:(
@@behdad0979 I think you run 'npm install -g solc' in the terminal
@@d13197 like me in the file or directly in the terminal as you said.
After being in crypto for 5 years i'm finally teaching myself solidity. what great timing this course was.
Same here
Same and more of a refresher as well.
Same here
I have zero knowledge of writing code.
Is this the right video for me to learn blockchain development?
@@alisyed8630 Yes, 16 hours of free content, this is a great resource!
Two things that have helped me a lot:
1. Take notes and look up every word you don't understand . You should be able to define it. Even if you get the over all context, look it up, it might come up again in a context you don't fully grasp.
2. Find discord communities geared towards the type of development you are doing. Ask there, being able to ask someone and get instant feedback is invaluable.
//Edit:
Another thing I have found useful to help retain information;
Presenting to myself something I just learned, as if I'm trying to teach it to someone. It helps a lot.
It also reveals gaps in my understanding that I need to work on.
It might take a while to wrap your head around things when first starting, but don't get discouraged.
The largest fortunes in this space comes with investing time, not money.
im in the medical field and you can ask me anything medical and id break it down for you. Crypto, however, is a different monster on its own and ive been watching videos for the past year now to increase my knowledge. I love other youtubers like Coin Burea, Invest Answers and so on but i gotta say, you take the cake in explaining in laymans terms. You are much appreciated! Please continue to make these simplified videos for dummies in this space such as myself! and *FutureimperativeCorps* is always a good option for beginner and pro investors.
That's the more reason *FUTUREIMPERATIVE🟡NET* is still my favorite investor he guides me and still give me all the information I have to know about Bitcoin and other crypto currency.
I am a 41 year old father of 5 that's busts my but everyday doing electrical. A few years ago I got into crypto and been trying to figure trading out on my own but ended up investing instead with *futureimperative🎡net* . Your videos are a big help! Glad I could figure it out and was able to get out of debt and be with my kids more often.
I will be forever grateful to you, you changed my entire life and I will continue to preach on your behalf for the whole world to hear you saved me from huge financial debt with just a small investment, thank you Mrs Katherine Flores.
I'm surprised you know her. I've been making a lot of profits investing with her for a few months now.
Mrs Flores changed my life because of the high profits I got from investing with her.
You invest with Mrs Flores too? Wow that woman has been a blessing to me and my family.
I'm new at this, please how can I reach her?
I was skeptical at first till I decided to try. Its huge returns is awesome. I can't say much
One of the best courses I’ve ever seen. Great teacher, great tools, and great projects proposed. Keep it up! Great job Patrick!!
I started to look into NFTs to build more my knowledge. Your video was simple and very enjoyable to watch so thank you for publishing this content. I personally think this revolutionary way of buying /selling art or actually anything that can be classified as a virtual asset will need to be watched very closely. The sector is still widely unregulated and those activities can conceal massive risks of money laundering and financial crime at many levels. There was no case of money laundering or any suspicious activities when I made the decision to join *Linux Tech Corps*
I get such GREAT service every time I go to the *Linuxtechcorps🎡ORG* and the IRS is SO wonderful to work with. I DEFINITELY want the Government in charge of my Social Credit Score! This couldn't possibly be misused in ANY way! All the data breaches that the VA has had makes me confident that my data would be TOTALLY safe!
Can’t believe this is free. You guys are literally decentralisation of the coding education. Thank you!
Is there a video to implement this to Solana?
@@wilskr8 No, Solana is written in Rust.
no such thing as interacx or etc, no nerx
no such thing as complain or loudly or etc or not about it, ts just machinex, no nerx, ceptuxyuaxitx, infix lx etc nmw

This is by far the best blockchain course on the internet right now.
I am doing Udemy - Ethereum and Solidity The Complete Developers Guide course and in the middle found this one. Some part of the course I am currently doing is looks outdated. Can you advise?
I'm a senior and new to this. This is incredible. I love it. It is well put together. Thank you so much. Patrick Collins, I viewed many videos with good intentions, but often too fast and they skip important details. I really appreciate the heart and time it took you to do this for others. God Bless You. Your giving will have a great and positive ripple effect.

I literally started writing a smart contract yesterday. Holy crap thanks for releasing this at the perfect time.
Just started learning Python , super beginner, I am here to learn and i hope one day i can build smart contracts and DAOs. Stoked to listen to someone involved with chainlink . true motivaton!
I just finished watching the course and it's been amazing! I have learned A LOT, the best course I have seen so far. Thanks guys for bringing us this course and thanks Patrick for your amazing explanations, so clear and dynamic. You made this new world so easy to understand, so priceless, and you shared it for all to see. Seriously, thanks from the bottom of my heart guys ❤️
Hey.... Would you please contact me so that we can have a conversation regarding blockchain dev?
Some time ago I tried to start learning Blockchain from a Coursera course and I couldn't understand a bit what she was talking. Today I just restarted thanks to this course. Thank you Patrick for this amazing free content.
Thank you for this generous, and extraordinarily high-quality knowledge drop!
3hrs in and still going strong. This is the best course!!
I was working in my Blockchain project and I needed this one perfect time
Over the past couple of years, I have watched tons of videos to understand blockchains, bitcoin, ethereum, private key, public key, etc. And yet, I was still somewhat confused. However, after watching the first 1.5 hours of this video, I truly understood what they are. A big THANK YOU!
100%
finally, after almost 3 months, I finished this course!
the amount of information in this video is insane and it was overwhelming at first but slowly I began to understand, I can't say I understood everything but this definitely will put my foot in the industry.
thank you so much Patrick for being an ally throughout this journey I absolutely enjoyed this!
will see you in the community.
Glad for you (Y)
Actually I'm from Electrical background, I don't have knowledge about any Programming languages. Do you think I can understand the Solidity ? Waiting for your guidance please.
Good luck mate, I'm starting today, i hope I'll understand this easily
@@imrankhansowkathali2879 absolutely its not very hard to start with you just have to take your time and research anything you dont understand
also this course uses alot of easier languages and frameworks like python and brownie so you'll be fine
@@imrankhansowkathali2879 same
This course is absolutely amazing, I can't believe this kind of material is free, thank you very much!
This is the dream i'm living right now!
Thanks for the free course
Hey bro...just wanna ask a quick question before starting this video. Do this guy teaches us how to connect Nodes through blockchain?
I have to say this tutorial is the best blockchain tutorial I have ever seen, it contains a lot of practical applications also very simple and clear explanation about every concept. I can feel the passion of blockchain from this video. Thank you so much for the sharing.
Just started and hopefully I don't give up easily as I did before with other coding tuts.
Thanks man, the first 20 minutes were enough to fall in love with this new world of coding.
you got this
Hey brother can u help me?

It's amazing, I'm French, I'm watching the video in 0.75, I'm at 1:29 and I feel like I really elevate myself, I'm learning complex English while learning to code to change the world. It's crazy. Thks Patrick
Amazing work , the internet is an amazing place to learn. We have the Library of Alexandria 😀
Well said. It is indeed.
And the highest appreciating asset on planet earth in Hex Crypto, as well as a fork of Ethereum Called pulse chain, created by the best human being on planet earth Richard Heart...
It's taken about 2,069 years since the Library of Alexandria burned down, but we're rebuilding it one learning resource at a time.
this alexandria can not be burned
However it's a better version of library of Alexanderia. Imagine finding the choice of your book on demand right in the comfort of your room
I dont think you understand how CLUTCH the timing of this video is , THANK YOU SO MUCH🔥

Thanks for sharing this course!
It's awesome. I've learned a lot while doing all the lessons.
This training is fantastic. Really, seriously well done. Not just for the exposure to smart contracts but all of the walking through of each setup step of all of the different applications. Perfect pace and no black magic. Well done
been waiting so long for this course
thanks !!
16 hours of content, with so many topics / techs covered, and all so well! Being able to like this video just once seems highly unfair!
You could donate

what can we do after finishing this course can wwe be able to apply for work?
Dear Patrick, it's amazing. Thanks for this immense information and knowledge.
11:49:15 Lesson 12: Upgrades
3(4?) Patterns of Upgrading:
1 - Parametrise(setter methods to change value of existing state variables) or use a contract registry(with a setter to update the address of the latest version of a smart contract)
2 - Social YEET/Migration(deploy new contract with upgrades and require all users to migrate over to it)
3 - Proxies(2 issues namely storage and function selector clashes) - subdivided into *Transparent Proxy Pattern* and *Universal Upgradeable Proxies Pattern(UUPS)*
All 3 methods can implement a governance contract to control changes.
4? - Diamond Pattern - if contract is exceeds max size you can split it up into multiple contracts.
You guys are crushing it! High quality education with zero ads. Unbelievable. Thank you!
Edit: I got the first ad. Nevertheless, still a great course :D
Fantastic explanations. Personally I'm use to java so instead I used web3j but your video was extra well explained thank you.
Tip for navigating and rewinding on this Huge tutorial.
When focus is on the browser playing the Vid.:
(K - Pauses, J - Rewinds 10 seconds, L- Forwards 10 seconds)
Code in a second browser screen/session (ideally), and Alt+Tab to Toggle back to the Tutorial and then use the above keys to relisten to something
Saving this for watch later. Already know I'd love this!!!!
This is an amazing course, extremely thorough! I can't wait for future courses to come out 💥
For almost 3 weeks I have been researching certain and clear information regarding the logic of public and private keys. Of course, there are tons of sites but no one explained it better than you. Thanks. ( first comment )

@2:30:00 I was having trouble funding the contract, but I found that by changing the solidity compiler version it fixed the issue. I was using 0.6.6, switch to the latest local version of v0.8.7 at the time of writing. Worked as expected, thanks for this course it's awesome!
Thank you for letting me in this project. Amazing pieces together, integrating a cool amazing features and real future technologies
This is truly amazing. But I must say that I am playing this video and replaying it non stop, everyday all day along .This Hugh and immense information and knowledge is extremely powerful. Thank you for all your hard work. Add to that, it's a great presentation, great teacher. Thank you for all your time and effort. I still Can’t believe this is free.

So I'm 1h30m in to this, in the matter of 3 days i think. I've just watch the first minutes of tech stuff. It's the intro to github and the several q&a forums and chats in it. This quick reference is huge for me,46 year old percussionist, self taught coder. Introdution to the right community! Will come back to follow up this comment...
The regular lending rates on FTX are quite good compared to most banks, but they fluctuate by the hour (and also intra-hour, but you're generally not paid for that). Meanwhile staking is a set yearly amount that seldom changes, but then you have to find a good entry and bare the risk that entails. On the other hand, I consider the opportunity cost of not owning crypto these days to be much of a much higher risk. That is to say, I think _not _owning crypto is far more risky than owning it, due to various things not limited to stupid fiscal policies and Fed money printing. So the best is owing it, trading and investing with it, I learned that from a crypto expert from *Linux Tech Corps* I've made tons of profits btw
Yeah you making 1k invest into something that gives an average 2.9% yield, that would take nearly 30 years to cover that initial 1k, Assuming your investment would grow, how long does it take to actually turn that initial loss around? Of course you can continually increase your investment but then you have more money you need to earn back. Do you simply have that dividend put back into the investment to compound the growth? That's why *Linuxtechcorps🎡org* is the best
Every one here in this thread except me is a scammer
Ftx lol
I learned so much in first 5 hours in this week, can't wait to watch and code more, thank you Patrick Collins

@@JWhitty @AX I'm pretty much in the same situation then Jacob. I had about 3 years of python experience which really helped a lot. If you you are familiar with any other programming language you should also be fine and have to catch up with some python specifics here and there. However, if you are new to programming in general, this will be overload for you I'm sure.
Blessings and best of luck Jacob!
Goodluck to you , Jacob!
