    Ethereum [SCAM ALERT] Dubai International Blockchain Summit Is A Scam

    [SCAM ALERT] Dubai International Blockchain Summit Is A Scam

    Posted: 14 Dec 2017 07:17 AM PST

    I recently was reached out to on LinkedIn by 2 presumably "sales managers" of the Dubai International Blockchain Summit (https://dibs.ae/). I had a 30-minute call with one of them.

    • The saleman created a sense of urgency pushing me to make a payment in the following 3 days.
    • He told me the event's place will likely change venue (because there are way too many registrations)
    • The price of sponsoring the conference seemed unusually low, even the highest package (especially that it included 2 nights for 2 people, transportation, tickets for visiting Dubaï's must-sees)
    • I was not sent the list of other attending companies.
    • LinkedIn profiles were deleted one week later (some others have probably been created).
    • They are listing known figures as speakers while it's totally fake (https://twitter.com/SamiHonkonen/status/934883477689913345)
    • The event's date was arbitrarily changed from the 9 of Janary to the 8th.

    I invite you to be cautious when selecting conferences to attend to, and to conduct your due diligence. I did not make any payment, but I can imagine how others could fall in the trap.

    Dear Vitalik, Thank you for all of the hard work by you and your team in the past year. Technical challenges remain but you and your team are equal to the task. Thanks from 1 human to another. You have made a lot of people very happy.

    "Ethereum killers"

    Posted: 14 Dec 2017 06:31 AM PST

    I've been hearing about so called "Eth killers" such as Cardano and EOS. I'm wondering what the community thinks about them. I realize this is the Eth subreddit but I'd like to hear some unbiased opinions on the matter.

    I really hope coinbase is upgrading their servers

    Posted: 14 Dec 2017 07:24 AM PST

    I know they're dealing with volatile markets which probably require a lot of processing power, but the whole point of Gdax is to be a semi professional trading platform. Can't make quick moves as a non-robot if the site crawls any time there's serious activity.

    I like you guys, and I know growth has been huge, but please adapt! If Blizzard adapted in 2006 you guys can do it now.

    Week in Ethereum News - December 14, 2017

    Posted: 14 Dec 2017 10:32 AM PST

    Having trouble understanding how Proof of Stake works, can someone clarify?

    Posted: 14 Dec 2017 12:45 PM PST

    Proof of Work

    To start off, I think I have an ok understanding of Proof of Work. Miners use computing power to validate that proposed transactions are valid. They do this by generating random inputs that go into function until it spits out the correct value on the other end, verifying that the transaction is legit. They do this for a group of transactions (a block) and once the entire block is validated, it gets added to the end of the main blockchain and they get currency for their work.

    That sort of thing makes sense to me because you're doing work to validate the transaction is real, but I'm struggling with Proof of Stake.

    Proof of Stake

    Here is how I hear Proof of Stake described:

    A person called a validator stakes some of their coin into the network. The validator then places a bet on a transaction they think is valid. If that transaction gets added to the blockchain, then they get a reward, a percentage of the transaction fee equivalent to the percentage of their initial stake. If that transaction turns out to be invalid, then they will lose some of their staked coins (I think this part is unique to Ethereum/Casper?).

    Hopefully I've explained the basic concept correctly. If so, it leaves me with some additional questions.

    Questions

    1. How is a validator verifying a transaction is real? In other words, how do they know which one to "bet" on? In PoW it seems like transactions are being validated computationally, but that doesn't happen in PoS, correct?

    2. How likely is it that a validator will bet on a wrong (invalid) transaction? Could it accidentally happen or would it always be malicious? When you are talking about having to stake 1000+ ETH, that sounds like a huge risk.

    3. How do transactions get proven as invalid? If it's from other validators flagging them, what is the incentive for someone to prove that a validator is malicious?

    4. How many validators is Ethereum expecting? How many people have over 1000 ETH (if that's the minimum, for example)? Doesn't this just give a small amount of people enormous power?

    I know I'm probably butchering these questions, but hopefully they give you some insight into how I'm trying to understand PoS, and maybe someone can explain why that is incorrect.

    Ever Participated In A Bad ICO?

    Posted: 14 Dec 2017 08:48 AM PST

    As Ethereum prices in USD terms skyrocket, won’t network fees in terms of Ethereum have to come down?

    Posted: 14 Dec 2017 11:35 AM PST

    I was just thinking to myself that Ethereum has doubled in price in a relatively short period of time. Therefore fees in USD terms have doubled (gas price and gas limits held constant but if anything gas price has gone up).

    If the fees don't come down in ether terms to remain somewhat constant in USD doesn't that threaten to kill off Ethereum usage?

    Clearly people wouldn't want to spend $20 on simple transactions that used to costs 20 cents.

    I know that for a change we could be a case of reducing gas prices to compensate, but then miners wouldn't want to pick up the transactions right? Miners work in terms of Ether but people doing things on the network will be likely to want to just hold their ether and not use if every little transaction costs a bunch in USD terms, right? And yes I'm thinking about the cats but not only.

    Doesn't this fee issue provide downward pressure or at least stabilizing pressure on the price of Ethereum?

    People want to use the network to do stuff; this increases the price of ehtereum. Ethereum becomes so expensive that network fees are so high in USD terms people think fuck it, I don't need to do that so badly, I'll just save my ether, it's valuable now. Network utilization decreases, demand for ether decreases, price decreases.

    Am I missing something?

    Bitstamp eth withdrawal question.

    Posted: 14 Dec 2017 06:22 PM PST

    So I currently have bought some eth on bitstamp and was going to withdraw it to an exodus wallet. At the withdrawal page i have some warnings that tell me I should not withdraw directly to an ico address and another one that I have to make sure the receiving party supports ethereum transactions generated from smart contracts.

    Does Exodus support ethereum transactions from smart contracts ? And It is not an ICO address right ? (Im still a mess about what ICO is exactly)

    Thank you.

    Ethereum and net neutrality

    Posted: 14 Dec 2017 12:18 PM PST

    Let's assume that after tomorrow, the Internet is no longer neutral (at least in the US).

    1 How would this affect the Ethereum network in the short term?

    2 In the long term could IPFS, whisper, ENS etc be used to fully decentralize the Internet and make any net neutrality bill irrelevant?

    How did early users of Crypto Kitties hear about it so early?

    Posted: 14 Dec 2017 03:35 AM PST

    I would like to be on the ground level (as everyone would) of things like this, however, that's impossible so I'd like to be as close as i can by doing the work. How can you become closer to finding these early?

    Can Not get MIST to sync. Can someone help me out and tell me how to move my coins from that wallet without syncing it?

    Posted: 14 Dec 2017 06:40 AM PST

    I have tried everything. It just won't sync and I'm so tired of it. I just want my money of this pos wallet.

    edit: Thanks to a user below, you can move your ETH from the wallet without having to wait for it to sync. Give him an upvote and point anyone with the same problem to his answer.

    Do You Really Own Your CryptoKitties? – Greg McMullen

    Posted: 14 Dec 2017 09:14 AM PST

    Is there a way we can see how congested the networks are?

    Posted: 14 Dec 2017 07:07 PM PST

    Just curious if there's some kind of data visualization site that shows how busy things are with BTC/ETH/etc. (ETC? 🤔) so we can have an idea of how bad the influx of traffic is.

    Kik is abandoning Ethereum because it "can't scale". Can the EF deploy some of its $500M to speed up scaling research and development? How about a roadmap with defined goals and launch dates? Some leadership would be great

    Dumped the Bigboy for Ethereum

    Posted: 14 Dec 2017 06:55 PM PST

    So today I made a drastic decision and dumped BTC for ETH. I'm here for the long run. Before you say I'm crazy, please note that it wasn't a huge amount.
