Gas is the fee paid when using the ETH network, on metamask you can choose different speeds and if you need faster speeds for a transaction to complete you pay a little more.

Here is a website to understand more about Gas prices https://ethgasstation.info/

Hi folks, Im enjoying this course ( night school ) for me. Just wondering who was the first person to create ethereum and how soon after bitcoin was started did eth enter the market?

How are you all intrepid pupils?!? I am extremely excited to be starting my third course in the academy. Ethereum blew my mind since the moment it was explained to me. I come from insurance and can see how it will radically transform my industry. I want to be a part of it! Anyone else in insurance?

Hi Krystell, I am interested to have a chat with you. Let’s connect also on Linkedin. https://www.linkedin.com/in/florincarare/

Hey, can help me understand a little more?
Where does the condition input come from?
For example, where do school grades come from? Who provides input? Is it for a school API or something like this? Is there any way to know if the input is correct or fraudulent? The owner of the contract provides the input manually?

I am very excited about what I have learned…LETS DO THIS THANG

I really enjoyed the Blockchain 101 & Bitcoin Course and I am so excited to move on to Ethereum. Looking forward to this new direction!

Hey everyone, I am a little confused on how Bitcoin could be more Private than Ethereum based on the activity questions assigned “How is the account model not as great as the UTXO model for privacy?” Since UTXO model will let you track where every bitcoin (and satoshi) came from all the way back to the source (of bitcoin first being mined) would that not make it less private since you could find out where all the BTC was going to and coming from?

Hi @Alzxcvb, hope you are ok.

Now here is an old reply referred to the same question, you might wanna read it to understand a little bit better why UTXO is a more private than the account model.’

Ethereum Introduction - Discussion

Hello sir, the UTXO model makes harder to track the provenance of the funds. There are still procedures to keep track of the funds provenance of a wallet (since the blockchain is public, there will always be a way to track any wallet funds). The Account Model is quite easy to track the provenance of a wallet/account, since you can track “from, to, quantity, hash, time” on the blockchain in a way more simple than UTXO. Even the fact of sending funds back to yourself, means an output with a inp…

[david_A]

Lets get this learning so we can get this moneyyyyyy!

[nscholten]

Got it. I am now ready to start the Ethereum course after finishing blockchain & Bitcoin 101.

[AlanS]

Hi, I have a question if anyone knows the answer.

Are all smart contracts on Etherium open source or is it possible to send a smart contract to the blockchain and keep its code private?

Tried searching the web for an answer but I’m still not sure. Thanks

[Victrix]

Lets dive in!!!

[SaraS]

Excited to start this course

Lets Gogogogogogog!!

So talking about the non fungible property of Bitcoin that Ivan mention in the UTXO model in this course.
How can somebody possibly know or asume that a BTC has been spend in crime or illicit transaction if you can only trace the public keys?
Can someone guess even the geographical location of the transactions?

@ivan
About the UTXO v/s account-model topic.
A couple of bitcoins are not always the same. How is the price of a dirty coin (one has been part of a malevolent activity) decided? Who calls the shots? What are the factors involved?
Can you provide an Elaborative view?

[Davey-Py]

Wow! I started mining ETH last year. I didn’t realize how lucky I was when buying GPUs because they are hard to find now and the prices have gone up. However, by reading some of the discussions in this introduction thread, I am realizing that I have a lot to learn in this ETH 101 class.

[Alzxcvb]

Thank you! will check it out!
