I HAVE INCURRED SO MUCH LOSSES TRADING ON MY OWN...I TRADE WELL ON DEMO BUT I THINK THE REAL MARKET IS MANIPULATED... CAN ANYONE HELP ME OUT OR AT LEAST TELL ME WHAT I'M DOING WRONG ?
I strongly advise you against self trading, it's really dangerous and had brought so many investors down, you need someone with the knowledge and strategies, someone dedicated to the crypto currency market business, and I will strongly recommend expert, Mrs Karen Charles
This is the very best explanation I have seen so far on RUclips. Well done. I just got done with a Bitcoin event in Osaka, Japan. Have you ever been here? I work and live here.
Cool man. Can I ask you, do you have any suggestions on how to get better knowledge on how Crypto's work. I'm at a point where I'm not sure if I need to know programming language, learn cryptology, or learn math (to help understand cryptology). Any suggestions are appreciated.
You made this easy to understand, the presentation was fun and lively. I love that you kept it short but also took the time to go into detail on the important things.
honestly I think this dude explained etherium better than other explanations ive seen... I understood the general idea but now have a better idea of how it actually works.
is this color-metaphor really correct? I never heard you can get the same color by mixing _two_different_sets_ of colors. I.e., you have A+B giving you C and you have D+E resulting into the same C. Aren't receipts for colors deterministic? Meaning you can always calculate back which two colors needed to get the one you need. Of course you don't know if it was _two_ colors in receipt. It might be 10 colors mixed together. But this is not what was depicted on the screen :)
hi! thank for this presentation. There are two things I don't understand: 1) what is the Difficulty algorithm in Ethereum (like in Bitcoin the block hash must start with a number of zeros) 2) what is the meaning of Uncles in the Ethereum block structure Thanks in advance
Those are good topics for a slightly more involved talk. You can read about these for now here: github.com/ethereum/wiki/wiki/Mining In Ethereum, in addition to the miner of a block getting a reward, the miner of blocks that end up being discarded as dead-end forks are also rewarded, when they are included by a miner as an uncle.
Very nice, engaging video with an enthusiastic sounding speaker. Loved the twist of explaining merkle trees through color combinations. I am trying to understand exactly how the smart contracts run. Are they only run if there is a transaction in the block currently being verified which makes an interaction with them? Like are they simply ignored if a block is created where no interaction is made with the smart contract? Also I don't quite understand the pricing. The creator of the smart contract couldn't know in advance how much memory and CPU it will need, and hence wont know how much gas to allocate for running the contract? Or is it even the contract creator who pays the gas, or is it instead whoever has an interaction with the smart contract at some later date?
Very nice, you guessed both of the answers! Smart contracts only react to transactions, they cannot passively respond to things. That's why there are projects like Ether Alarm Clock, which allow you to put a bounty up to "wake up" your contract at a later time. The Ethereum Virtual Machine (VM) has a price very every operation it can perform, measured in a unit called "gas". When you send a transaction, you include two parameters: Gas price (how much ether you're willing to pay per unit of gas), and gas limit (the maximum amount of gas you're willing to pay for during the transaction). During the execution of a transaction, before each operation, there is a check to make sure this will not exceed your gas limit. If it does, it throws an error, reverting all the changes your transaction made, other than charging you the gas fees. For this reason, a person publishing a smart contract pays enough to store that smart contract and set it up, and each person interacting with a smart contract pays enough for it to run their instructions. There are some changes planned for the Metropolis (EIP 86) that will allow any account to pay the gas fees, so then if you want to make your contract cheaper to use, you could pick up the bill for your users. I hope that helps!
Ah so simple setting up a smart contract involved instructions with a gas price. That is interesting. So if I was to speculate on the solution you describe. As a user you set a max amount of gas to prevent a faulty program from running far more instructions than you intended. Not sure if I get the max unit price for gas. I had assumed you bought the gas with ether in advance. But this makes it sound like you allocate some ether to the executing of the contract, which is then used to purchase gas in the market as needed. If there is a market? Or is gas price set by the miners, rather than traders. I assume ether price is determined largely by trading kind of like bitcoin, but that gas price might form in a slightly different way. Perhaps in relation to scarcity of computation power available on each node. E.g. if there are a lot of smart contracts running there will be shortage of gas/computation power available and hence gas price has to increase??
Your intuitions are so correct that I almost think you're trolling me by asking questions. Yes, you set a max gas amount so that you limit your loss in case of a faulty program. In fact, when an error is thrown in Ethereum, you lose your gas limit x your gas price of ether. When you set your gas price, you are declaring how much you will pay the miner for processing your transaction. This creates an auction scenario, where miners do mine the highest value transactions first. Yes, this means during busy periods, there are peaks in network usage cost, much like surge pricing on uber or lyft. Last week we saw a big glut of transactions being processed, and gas costs got quite high, around 51 gwei, and that's just because the big sale of the week (Status) limited their contributors to using 50 gwei per unit of gas. A unit of gas is just the smallest indivisible amount that is charged (in ether) to use the Ethereum computer. Every operation has its own gas cost, and they're priced to reflect the performance cost on the validator's computer. For example, adding two numbers is cheap, storing a number for eternity is expensive. Forgetting a number gives you a refund! That's all called "metering" and you can look up the price per operation online.
Bonus fun fact about how operations are priced: On the first day of Devcon 2, there was an attack on the Ethereum network where the attacker slowed down the network cheaply because the exponent operation was too cheap for how fast it computed on one client, bringing geth users down for the morning, until a patch was released.
Thanks for the thorough explanations. I feel I am really starting to grasp how Etherium works now. It was very confusing initially, what it even was. It really sounds like a brilliant technology with a lot of potential.
How exactly are you going to solve scalability issue ? since it's decentrelized , it means every transaction needs to run through every node (or process/verify ) right ? Don't you think that as this platform grows bigger bigger the speed of all those contracts and transactions would be really really slow since it needs to be verified by all nodes ?
Moon Bilguun There are several strategies for scaling, and they all have to do with ways for people to not verify every transaction. You can essentially have a consensus protocol for individual branches of the merkle tree, and join them with a lower root consensus protocol. Maybe a good subject for another talk, although there are so many projects on it, I'm not a full expert right now.
Thanks for this! Very interesting.... can you help be understand how something like Mt Gox can happen. If BitCoin was using the Merkle tree..... how can some many bitcoins go missing?
Mt. Gox was a centralized exchange, so people trusted this website with their account private keys, and someone with access to those keys ran off with them. MetaMask puts you in control of your own keys, so security becomes your own responsibility, namely, backing up your seed phrase, and avoiding getting your computer hacked.
The key/account management is a pretty different topic than the merkle data structure of the blockchain. The merkle tree is how the information is all stored, but the clients decide what is a valid new state, and this enforces rules about account ownership, including key signatures.
This "intro" was way too nebulous and esoteric to be an intro. This is for someone that already has a little background and knowledge about the subject. It's not for the average Joe that works 9-5 and has very little time to dedicate to understanding this stuff.
Actually , i couldnt do 2FA because i lost my phone, now i couldnt recover my account for many days, the account recover webpage was broken i think. i got my account back thru a manual email, not the account recover system. But i known my email and password, and they kept denying the account recovery. i finally did have to get the manager's (supervisor's) attention, and not the robots attention.
Yes, I understand rainbow tables. Who's proposing giving out your social security number's hash? An ethereum address is the hash of your public key, so it's only the hash of public information, it has nothing to do with a social security number.
Oh yeah, good catch. I agree, you shouldn't actually send a hash of a social security number, just used it as an example for a mostly non-technical audience.
The clearest intro to blockchain & Ethereum I've seen, period. Great job Dan!
Thanks!
Spoke to Dan today. Honestly, one of the most geniune and brilliant minds. An integral part of our industry, he's really great!

Same here, My portfolio has been going down the drain while I try trading,l just don't know what I do wrong
Trading with an expert is the best strategy for newbies and busy investors who have little or no time to monitor trade

this guy made merkle trees seem *elementary*. what an incredible teacher! the color analogy blew my mind 🤯
I really like your joy and passion... nicely done!
at 1:18 his slide says "Hash of this slideshow --> ??????" if I understand hashes correctly, it would be impossible to fill in the ??????, right?
Clayton Roche Good eye, that’s exactly right!
it depends on what hash function you are using ^^say if person A uses hashfunction A , and you dont have the same function, it will be impossible ,
@@DanielFinlay Can you please let me know why ? If a mp3 file can be hashed then why not a ppt ?
Not just a great introduction on Ethereum, but a great explanation on blockchain. Thanks:)
Let's talk,I have something bigger to introduce ⤴⬆⤴
This video needs to go viral. I will be sharing, thanks!
So far the best video that explains the functioning brilliantly. Thank you very much !

That was a great introduction. Thank you.
Thanks! You're very welcome.
This is the very best explanation I have seen so far on RUclips. Well done. I just got done with a Bitcoin event in Osaka, Japan. Have you ever been here? I work and live here.
Yes, it was one of the best. Cleared many of my doubts.
Thanks a lot!
I haven't been to Osaka, I was just in Tokyo for the first time and it was awesome, and a lot of people recommended Osaka, so hopefully someday!
Cool man. Can I ask you, do you have any suggestions on how to get better knowledge on how Crypto's work.

Louis CK explaining Ethereum
Awesome video! Dan is great at explaining as well as a really good presenter!
You made this easy to understand, the presentation was fun and lively. I love that you kept it short but also took the time to go into detail on the important things.
Excellent overview. I added this video to my favorite list and will look for more stuff from Dan.
I am really interested in becoming a blockchain developer and need guide, how do I get started please?
Quick and comprehensive introduction.
What a great guy ... I almost never compliment dudes but this guy is great! Thanks for the info very helpful
Lol! Thanks! You're very welcome.
wrong, idts. man can be higher value, many w low vx shtx. stupx w orbitor
Why do you never compliment dudes?
why does he sound like he’s just snorted about 200 lines of amphetamines..
You should compliment more dudes.
Great video. I like the way you explains. keep up the good work.
This video is priceless! Great work explaining stuff. Cleared a lot of questions.
This video is epic!

Best explanation I came across by far. Thank you very much!
This talk is enthusiastic and awesome
nice introduction , would love to hear more about the limitation of ethereum network.
You can get in touch with me.
This could be used to double check anything any amount of times. For security
Really good speech, but 75% of the video is about generalities not Ethereum. Skip to 7:37 if you're already familiar with Bitcoin.
Finally i meet with the right ETH minner ...Its feels cool i bet

Meta Mask company: Ahead of the game for years!
What about tokens?
Thanks for this! Very interesting.... can you help be understand how something like Mt Gox can happen. If BitCoin was using the Merkle tree..... how can some many bitcoins go missing?
Mt. Gox was a centralized exchange, so people trusted this website with their account private keys, and someone with access to those keys ran off with them. MetaMask puts you in control of your own keys, so security becomes your own responsibility, namely, backing up your seed phrase, and avoiding getting your computer hacked.
MetaMask ahhh... so they stole the private key.... could you use a Merkle key for a private key? .. . I guess it then would not be private.
The key/account management is a pretty different topic than the merkle data structure of the blockchain. The merkle tree is how the information is all stored, but the clients decide what is a valid new state, and this enforces rules about account ownership, including key signatures.
Thanks. I have a much better understanding now..... very helpful. Thanks again.
I will have to agree with the other viewer this is a very well made and energetic presentation
wow, you are amazing. I am a blogger and I am watching tons of vids on crypto. This guy is THA BEST.
