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!
*Finally someone who is willing to teach us younger guys instead of pushing some bs course on us. Appreciate it*
I appreciate *Virtual crypto mines* a lot
Extremely point by point video Well I will also say this here, Most people don't understand the concept of "buying the dip" buying the dip is all about buying digital assets when their prices are down and selling off when the price rises. Holding is great, although trading is far more profitable. I was able to grasp the knowledge of trading crypt0 assets early enough, but I was still limited due to my lack of technical understanding of how to analyze the digital market, all that changed when I encountered *VirtualCryptoMines🟡COM* , I must confess it was easier to understand with the assistance of Andy that has made me over good ᴄoin.

Such an amazing and talented young men with so much talent on explaining as smart as possible how to actually earn money from crypto and not having to rich much money . Thanks dude for this video keep it up and a shout out to *Linux tech corps* for being real with their investment plans
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
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!
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. 😃

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 😂
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.

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?
Hey i'm new to this but i was wondering the same and found this on the Solana documentation: Does Solana support Solidity? Not right now. Solidity was built to work really well for the Ethereum Virtual Machine (EVM). However, Solana’s smart contract VM was designed with fundamental differences from the EVM and so it currently does not support Solidity.
@@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

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

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

Absolutely great... I have waited for this for so long
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.

Wow! 16 hours? My respect for putting together such a great and vast content here for the community. This stuff is life changing and will help plenty of people. Including me. Thanks a lot
what can we do after finishing this course can wwe be able to apply for work?
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?
This course is absolutely amazing, I can't believe this kind of material is free, thank you very much!
Thank you for this generous, and extraordinarily high-quality knowledge drop!
Patrick, this is fantastic! It must have taken so much prep and work from your side to put this together and the world appreciates you! I've listened to many IVY league lecturers and your flow, explanation, topics, and overall understanding of the concepts and technology and ability to divulge should be a model for every teacher. Thank you!
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.
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
This is a gold mine if you're getting started with solidity. A must watch period!
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 )
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.
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.

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%
been waiting for so long for this 👏🏻👏🏻👏🏻thank you so much for making it 🙏🏻
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

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. Dear Patrick you are literally decentralizing the education of blockchain programming. Many thanks and God bless you.
The best thing I can do now is to invest in shiba, which has many better advantages over other cryptocurrencies. Although I haven't fully understood it yet, but l've been able to earn 500$ everyday
Dear Patrick, it's amazing. Thanks for this immense information and knowledge.
@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!
This is an amazing course, extremely thorough! I can't wait for future courses to come out 💥
I learned so much in first 5 hours in this week, can't wait to watch and code more, thank you Patrick Collins
hey dude...! I think by now you'd have completed it...! does high level of mathematics is require to learn this course or is it ok to go without knowing high level mathematics?
@@_VIVEKNANDAN hey, sry for the delay, no. no need for hight level math, some basics is enough.
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
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.

Fantastic explanations. Personally I'm use to java so instead I used web3j but your video was extra well explained thank you.
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
If only you know what the future says, you'll know that indeed cryptocurrency is the future, investing in it now will be the wisest thing to do. Hold! And you"ll thank yourself

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.

To be honest I bought a course on udemy wanting to learn Blockchain programming and I've watched it to 45% complete but I found this course and I took a bold step to download it and I watched the first 2hrs and I could see what I'm missing from there.

How is it going?

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
