    Please help to advise a better design for Etheremon smart contracts

    Posted: 20 Dec 2017 12:50 PM PST

    Hi everyone,

    We are developers of Etheremon dApp. Many of you mention about the potential risks in our smart contracts. Yes, it is our mistake. Instead of spreading the FUD, could you please suggest a way to help us fix it properly. We highly appreciate that.

    For a quick fix, we can easily update the withdraw function to only get out our profit and do not touch on user's balance. It is easy but we get a problem with this approach (which leads to our unintended-design withdraw function like current one). We likely need to update the Etheremon Processor contract frequently as it is a game, some logic must be changed (such as add a new feature in battle, shop, transforming ..). If we do not have a good function to transfer data between old and new contracts easily, it will give a very bad user experience. For example, in the case of transferring Ether out of the contract, if we can only transfer the profit out, how can we transfer user's balance from the old one to new one. If let user make txn to transfer, it is very bad and not a friendly way (imagine we have thousands of users, how can we ask them to do that in short time). It would be great if you could help to suggest a solution, we are trying to fix it as soon as possible.

    Here is our smart contracts, there are two contracts: 1. Data contract (should not be changed, as it keeps the sate of users): https://etherscan.io/address/0xabc1c404424bdf24c19a5cc5ef8f47781d18eb3e#readContract 2/ Processor contract (should be changed time to time): https://etherscan.io/address/0x8a60806f05876f4d6db00c877b0558dbcad30682#code

    Thank you so much

    Information for miners on how to improve their uncle rate

    Posted: 20 Dec 2017 03:29 AM PST

    During the recent days the Uncle rate of the Ethereum network has again increased significantly as it can be seen here.

    While most large mining pools manage to keep a reasonable low uncle rate, lots of smaller miner and mining pools exhibit a unusually large uncle rate as it can be seen here.

    Generally we found Parity to cause an elevated uncle rate with a large tx queue. Therefore limiting the tx queue size to 8 times the current block gas limit seems to significantly reduce the uncle rate. This can be done by running Parity with the following argument: --tx-queue-gas 70000000. Furthermore if you operate multiple mining nodes it is always a good idea to establish a direct connection between them by adding them as a reserved peer.

    If anybody has some suggestions for Geth on how to reduce the uncle rate, please feel free to share.

    Can anyone ELI5 why someone would invest in an erc20 token instead of just ethereum?

    Posted: 20 Dec 2017 12:18 PM PST

    Firstly, my apologies if this isn't the right sub for this post. There are so many erc20 tokens/projects that I'm intrigued by. Naturally I purchase their token (to use some and hodl some). Since erc20 tokens exist on the ethereum blockchain and gas prices are are universally recommended based on the ethereum network, why wouldn't an investor just buy ETH? Could you think of the native ethereum token like buying an index fund, whereas the erc20 would be individual stocks?

    p.s. I know the stock market is vastly different than cryptocurrencies/dapps, but I'm just trying to wrap my head around this.

    Who the ETH are you? Give yourself an alias DApp.

    Posted: 20 Dec 2017 09:44 AM PST

    Hi Everyone.

    I made a DApp that I want to share with you today. Today if you want to be known you have two major options. You can be known by your address or go with the fancy fancy Ethereum Name Service.

    Those are both well and good, but how about something smaller and less fancy. So I'm presenting to you...

    Who the ETH are you?

    Or, Who the ETH? or, WTE? For short.

    This is a smart contract let's you pick a username/alias/any text you want for your address and let's any DApp look it up. There are no restrictions to the name you use other than if you make one too big you might run into a gas problem :). You can also change your name at anytime. You can call yourself the same things others call themselves. Who cares? I don't.

    So, how do you do it? Check out our Fancy Website!

    But wait Moron, you say, it is probably not a free service. You would be right, well, maybe, or not. The first 500 people who set their name get to do it for free (well, you know, tx cost). After that, it is just one finney to register.

    But hey, this isn't just for you to give yourself a name. Let's say you have your own DApp and want usernames but don't want to have to figure it all out. No sweat, I made a dev site that shows you how you can use Who The Eth? for your naming. Also I show you a way that if you get users to sign up, you get the money, cause, I mean, that means you did the work. Click here for the dev info.

    If you have any questions, let me know here, I'll try to answer!

    Or if you would rather, Check out my white paper!

    Thank you for your time, hope to see some creative names in there, oh ya, it is UTF-8, so Emojis work, just saying.

    Side note, google DNS is messing up my site, if the link doesn't work try using my backend site.

    A day or two ago

    The story I must tell

    I went out on the market

    And on my back I fell

    A gent was riding by

    In a two-coin open sleigh

    He laughed as there I sprawling lie

    But quickly drove away

    Crypto Bells, Crypto Bells,

    Crypto all the way

    Oh what fun it is to mine in a one coin open sleigh, hey

    Cyrpto Bells, Crypto Bells,

    Crypto all the way

    Oh what fun it is to mine in a one coin open sleigh, hey

    Now the ground is white

    Go it while you're young

    And crack, you'll take the lead

    Cyrpto Bells, Crypto Bells,

    Crypto all the way

    Oh what fun it is to mine in a one coin open sleigh, hey

    I was hoping to have Andreas Antonopolous book "mastering ethereum" as holiday reading but unfortunately it's not out yet. Can anyone recommend an authoritative and exhaustive dive on ethereum that would be similar to what Andreas is trying to do? Thanks!

    New ETH Wallet User - Help with transfer not going through...

    Posted: 20 Dec 2017 09:36 AM PST

    No need to upvote, I just need some help.

    I downloaded the Ethereum Wallet and launched it and let it sync. I sent ETH from HubMiningPool to the wallet and got it. I'm now attempting to transfer some to an exchange and it's not working...

    The transaction is listed at the bottom with 0 of 12 confirmations and the transaction ID is not visible on etherscan.io. I used the default fee slider value. It's been 3 hours.

    My wallet balance still shows my full ETH amount and hasn't deducted the transaction.

    What do I need to do?

    What's the incentive to run a Raiden (or micro-Raiden) node?

    Does a node collect Wei dust from transactions similar to how a Bitcoin Lightning node collects Satoshis for facilitating transactions?
