oh i see thanks a lot!
So far so good would just be nice if the admin/team could be more engaging with questions/critique but overall Iām enjoying it.

Hi crypto fam! I am loving the academy so far and would love to get to know some of you fellow students and maybe team up on some research or projects. I am learning programming and hope to build my own project using MORALIS very soon. Letās make the most of this bear period and build something together. Message me if youāre interested in having another crypto friend to build with and share market research. I plan to build a big crypto community. Together we are smarter and stronger. Peace. Joon

Very well put together course material Ivan. Literally anyone can understand the material and catch up to it. The short course style and individual videos for each topic is highly effective.

Hello
I am a student who is about to start looking for a University . Any recommendation for a Udergraduate program that has relation with Block-Chain? In which university?

I am really excited to continue with this course. I started about one week ago and I
have already learned a great deal. So far the lessons are easy to follow. I have been
looking for a career change for a long time, I have found it!

What do all blockchains have in common like the Bitcoin Blockchain, the Ethereum Blockchain, and other blockchains? The definition for a blockchain is a distributed immutable ledger. The major use case for blockchains is to track the ownership of assets, things that have value. I know that once you make a transaction on the Bitcoin Blockchain and it is confirmed, it canāt be changed or be removed. I know that the Ethereum Blockchain supports smart contracts. Are smart contracts immutable just like transactions are? If they are immutable then what happens if you deploy a smart contract with a bug in it? Can you deploy a bug fix to a smart contract to fix it or do you need to deploy a new smart contract without that bug to the blockchain? Can you upgrade your smart contract, add features to it? What happens to an old smart contract if it replaced by a new one? I would appreciate it if someone would answer these questions for me, please.

You would have to deploy a new contract. Some of the contract can be destroyed which will return you some eth for releasing the storage for that contract.
To make the dapp upgradable some use proxy contracts so they can change the contract logic without disrupting the dapp functionality when this is the case.

Thank you so much, Alec!
just jotting down some notes on the ideas/underlying philosophies i ran into during this course
consensus
ātapped into one human thing; we all want to make moneyā === true, but there are other values too===
security and immutability
āon the internet you can not really transfer value because itās so easy to copy and paste everythingā === disagreed: internet can transfer but canāt (yet very effectively) ISOLATE valueā¦ e.g. it is valuable to 1) read up on so much of that info on the internet, 2) have a social network in which to participate, 3) blah 4) 5) 6) ā¦ i.e. more is valuable than just moneyā¦ ===
High availability
ācompanies claiming we donāt want to make money, itās all about our values blah blah blah; itās falseā === itās both true and false for company and consumer ā¦ true: things valuable to the company will sometimes make and sometimes lose them money AND sometimes with the goal of satisfying a consumer need (and sometimes NOT with that goal) ā false: company values can also be a clever alibi for subverting consumer demand into funding ulterior motives, e.g. defense contractors charging 1300$ for a certain wrench used on certain airplane bolts, letās sayā¦ in such a case the value of money to the company is clearly more than the productās/serviceās value to the consumer.
i.e. value priority matters a lot to whether this is true or false ===
wondering about anyoneās inputā¦ maybe iāll try tagging @thecil just for fun/practiceā¦

Hello, hello!
So far Iām enjoying the course lectures. I know more about blockchain now than before I started, many thanks Ivan for making great video content. Iām looking forward to keep on learning and see where this journey takes me. Cheers everyone and good Luck!

yes ofcourse thats theoretically possible, but by then no one would probably use traditional computing since there would be no incentive for the insignificant amount of work your machine contributes to secure the network,i.e no benefit to keep your computer plugged into the system, those machines would be rendered obsolete. I guess by that time the blockchain itself could be secured by quantum computing nodes.

Hi! Iām really enjoying this course. But I have some disagreements that I would like to discuss because maybe Iām wrong.
In benefits of blockchain, reduced costs and speed where mention as key points.
But as long as Iām concerned. A regular SQL database has way faster read and write mechanisims, so I think that if yourāre business really relys on this and you donāt need that much security or traceability, a regular database would be better, also the costs of implementing a SQL database are way cheaper, maybe mainteining it not, but I would really like to see your points of view on this.
Thanks!
