    Caution. Remember to set the gas limit and gas price correctly. Someone just spent $2.5k on fees and moved nothing.

    Posted: 02 Jan 2018 03:21 PM PST

    Its looks as if someone (not me) has unfortunately set the gas limit on their transaction too low and the gas price too high, resulting in spending a little over $2.5k in network fees and having the transaction fail as the gas limit was reached.

    Edit while posting: I've just looked at the accounts history and there are actually 3 transactions at this gas price, spending over $7.5k to send 0.6 eth. I'm now unsure whats going on...

    Where can I spend my ETH?

    Posted: 02 Jan 2018 06:54 AM PST

    Obviously I could go and buy rival coins like BTC to go purchase things, but is there any early adopters out there I can spend my ETH directly at? Are there any compiled lists out there of places accepting ETH as payment?

    I created a non-profit academic Ethereum project (read: experiment) that seeks to commodify everyday products into appreciating assets. I need some preliminary data to get started and would like your help in exchange for a chance to win a small amount of ETH (0.13)

    Posted: 02 Jan 2018 01:35 PM PST

    Hello /r/Ethereum

    I have lurked around in this community for quite a while now and am very excited to share my project with you all. It is a non-profit academic experiment called the Rudar Project which seeks to explore ways the Ethereum network and platform can be used to commodify everyday products in a manner that increases economic efficiency by increasing consumer surplus without decreasing producer surplus. I would like to explain more but I keep getting blocked by the auto-moderator so here is a link to an introductory article if you would like (please provide feedback): https://www.rudar.io/introduction-to-rudar-project.

    I have a 2-3 min survey I would like you all to take and maybe share. I have had trouble getting the sample size I need to I am offering a chance to win 0.13 Eth to the survey-takers if I can get to about 500 responses. I realized that amount is not a lot but it is all I have for now (I am not making any money off of this).

    Here is the survey link if you are interested:

    Thank you for reading. Have a nice day.

    What happened to Etherdelta? Where's Zack and why the ICO?

    Posted: 01 Jan 2018 11:25 PM PST

    I was always super amazed about Etherdelta. The project was generally given as an example that good projects don't need an ICO and it got tons of love from Vitalik. However, they're currently doing an ICO and I don't see the only actual contributor (Zach Coburn: https://github.com/zackcoburn) mentioned under team: https://crowdsale.etherdelta.com I see a bunch of Chinese faces that I've never seen before. So in short: what happened? Did Zach sell his project? I don't see any announcement or news about it anywhere. I expected that such a dramatic shift of the most-used dApp would at least find some news response.

    Casper FFG - Are Checkpoints at 50 or 100 Blocks?

    Posted: 02 Jan 2018 06:21 PM PST

    I see a lot of references mentioning checkpoints at 50 blocks. However, the Casper FFG Basics paper says the following about checkpoints:

    The genesis block is a checkpoint, and every block whose height in the block tree (or block number) is an exact multiple of 100 is also a checkpoint.

    So is the checkpoint every 50 or 100 blocks?

    Also curious to know how many blocks will be in each epoch and the number of hours per epoch.

    Building a fun, non-ponzi DApp game. What do you want me to build?

    Posted: 02 Jan 2018 01:43 AM PST

    I'm an experienced web developer and I'm sick of these ponzi/fake games coming out. What games would you guys like to see on the platform? I'm keen to build one but don't have a lot of ideas at the moment. I can promise a prototype within a week if it's relatively simple!

    Why are Casper contracts written in Viper?

    Posted: 02 Jan 2018 03:31 AM PST

    We're seeing a first generation of smart contracts on Ethereum along with a first generation of fun exploits. Those are pretty much entirely written in Solidity. We start having sorry best practices, libraries and tools. Despite these first efforts, one of the hottest developments of the foundation, Casper, is written in Viper. https://github.com/ethereum/casper/blob/master/README.md Why? Wouldn't we all benefit by jointly pushing in one direction, ideally the one that has most community support in these really times (i.e. Solidity)?

    Did I just delete my eth wallet?

    Posted: 02 Jan 2018 04:41 PM PST

    So I was trying to speed up the sync process, I was looking up videos on youtube and such.

    So my files didn't exactly match the dudes so i was messing around trying to get it to work.

    To be honest I don't quite remember what I did, but i deleted the ethereum folder in %appdata%. I then went into my trash to recover it and found only the GETH folder. - My keystore is empty and not in my trash

    All my ethereum wallet files are safe in that folder and untouched.

    Did i just delete all my eth?

    Please help me i'm freaking out

    How can a mnemonic phrase restore accounts added after initialization?

    Posted: 02 Jan 2018 08:02 AM PST

    I've gotten myself a Ledger Nano S, and I've written down the mnemonic phrase. My layman understanding of this is that if my actual key is "abc" my mnemonic is a different representation, for example "alpha beta charlie" (as a simplified example).

    However, as the mnemonic phrase was given when the device was initiated I can't quite understand how my wallet can hold multiple accounts for each coin, and the phrase still "knows" all accounts that were created initially AND those added afterwards.

    Does anyone have a ELI5 explanation of how this works?

    What is the punishment for a validator node being offline in Proof of Stake (Casper)?

    Posted: 01 Jan 2018 11:15 PM PST

    Basically the question is if there is some kind of punishment for a node being offline for some time during staking/validating period. Let's say my node has been chosen from a validators pool. During the validation period my node is offline 0.1% of time because of ISP's fault. Will my staking eth be slashed? Will I lose everything by not being accessible?

    Thanks

    Exchange gas price defaults and fees question

    Posted: 02 Jan 2018 03:44 PM PST

    Is anyone currently working with the exchanges to identify safe gas prices based on network usage? It seems several exchanges upped their default gas price during the height of cryptokitties mania and left it there (Binance, Bittrex). I'm seeing nothing but 51-55 gwei gas price txs from these exchanges which seems overpriced right now. I know EthGasStation has an api that can be used to for median / standard / safe gas price determination, but it seems none of the exchanges are utilizing it, in favor of steadfast defaults. IMHO it is resulting in an overpayment of fees incurred by their customers and not a very friendly operating model. I suppose the argument can be made that it guarantees they get into blocks during periods of high stress, but I feel like that's a poor practice that actually artificially drives the safe / median gas price up for the rest of the network as well.

    Noob question: Is solidity able to have formal mathematical verification like haskell and if not will this ultimately limit ethereum? Can ethereum be upgraded to use formal verification? What are the trade offs? and also just tell me anything about this. THANKS

    title.

    If i said any of this in a way that is idiotic just correct me please. Im just a lowly hobo that is interested in science trying to get general ideas about all of this stuff.

    and no im not interested in other coins that are working on this stuff or what they are doing i just want to know about how this relates to ethereum specifically

    Can't sync the Alpha Casper Node

    Posted: 02 Jan 2018 07:10 PM PST

    I've tried on two separate computers, one is running x64 Ubuntu and the other is running x64 macOS. I have tried starting the node with both of the provided bootstrap nodes, but neither works. The last messages I get in the console are:

    INFO:p2p.peermgr waiting for bootstrap WARNING:p2p.discovery.kademlia recv ping from self?! WARNING:p2p.discovery.kademlia recv ping from self?! WARNING:p2p.discovery.kademlia recv ping from self?!

    Full console output

    I have tried port forwarding port 30303 on my router using both TCP and UDP and opening the firewall to port 30303 in Ubuntu Server. Neither of these have had any effect. The peer count fluctuates from 0 to 3 and the node is listening for peers but it is not syncing.

    When I try to mine, the block header is switched to the next block starting from 0 after a minute or two over and over, but no Ether is being put into my account. I don't think it's actually mining.

    Does anybody have any ideas?

    Help with ENS

    Posted: 02 Jan 2018 08:27 AM PST

    Last summer I bid and won some ENS names. I backed up the .json files, and have all those, but I lost the wallet I was using to bid on. How do I restore the ENS names to a new wallet so I can view them, and see what domains I won on, as i forgot some of them.

    Thanks for help ahead of time.
