    When is reddit going to accept ETH for reddit gold?

    Posted: 19 Nov 2017 03:54 PM PST

    Does anyone else think it's odd they're still only accepting BTC?

    If I want to donate to ethereum core developers where should I donate.

    Posted: 19 Nov 2017 04:41 PM PST

    As a believer in the project and also skeptical of the current ICO climate, I want to donate a bit to contribute to ethereum developers not doing ICOs. I'm no opponent of ICOs per se, but many of them would contribute a lot more to the ecosystem if they just used ether instead of inventing a new coin. I know Vitalik has spoken a bit about a fund, is the fund already set up?

    Only place I know of is this: https://www.ethereum.org/donate Would that be the most proper place to donate?

    Any insight welcome, and hopefully more people here will contribute. After all, many of us has made a bunch of profit without doing much.

    What effect would net neutrality have on the ETH network?

    Posted: 19 Nov 2017 12:18 AM PST

    Let's say the US does away with neutrality and other countries follow suit. Will this have an effect on the network? If so what?

    What is your favorite example of a realistic smart contract?

    Posted: 19 Nov 2017 11:40 AM PST

    Whenever I'm trying to explain Ethereum, I always fail to have a good example of a smart contract in mind. The typical ones look to me always too naïve to implement in computer code. E.g. "you don't trust trucker Tom, so let's make a smart contract that he gets paid once the GPS of his truck is there" - like nobody has to check that the cargo is intact (and sign off on that). I also (unfortunately) think lawyers are always needed for many situations, as it's very difficult to make a contract that covers all possible cases completely and accurately.

    What's a good example that I could use?

    Synchronous, partially synchronous and asynchronous consensus algorithms

    Posted: 19 Nov 2017 06:44 AM PST

    Could someone explain the practical difference between synchronous, partially synchronous and asynchronous consensus algorithms?

    There might be some trade-offs but from my understanding asynchronous protocols rely on fewer assumptions about the underlying network and should be a better fit for decentralized protocols. E.g a fully asynchronous sharding scheme seems like the best way to scale out.

    Also, dPOS schemes which at least involve partially synchronous protocols seem to rely on a limited validator count. Tendermint core (Cosmos) is limited to 100, the "EOS cartel cloud" only allows 23 validating nodes. So asynchrony also seems to be the key to real dezentralization as it should be.

    Additionally all dPOS schemes i've seen so far have a deterministic process for selecting the next validator. This introduces new attack vectors since adversaries know in advance which validator/s will be responsible in the next round (ddos etc). In general strong randomness seems to be quite important as it keeps the network unpredictable for the adversary.

    So... are asynchronous protocols which are build on strong randomness the holy grail?

    Blockchain OS

    Posted: 19 Nov 2017 10:52 AM PST

    https://www.coindesk.com/intel-ledger-partner-cryptocurrency-storage-integration/

    I wasn't exactly sure which subreddit to post this to but I figured r/ethereum was a good place.

    I saw this article a while back and it got me thinking: "What would a blockchain OS look like?"

    Now I know that Intel and Ledger are not partnering to create an OS but my mind wandered down that path, several times over the last couple of weeks.

    One way I thought that this could work is with phones. It would be an OS that would hold all of your personal data that companies and governments use daily. This would allow for ownership over your virtual self and allow you to sell your data and to know when this is accessed. So I think for this to work, you would need a way to record whenever information is accessed on the phone from a 3rd party (such as signalling when the camera was accessed without your knowledge, etc.). The problem that I imagined in this scenario is that if some clever hacker manages to rewrite the code of the OS so that it stops signalling when the phone's hardware is used or data is accessed, then this solves nothing.

    So today I thought about another way a Blockchain OS could exist. What if there was a network of nodes constantly verifying all copies of this blockchain OS code so that any changes made to it are caught by the nodes and then the user is notified immediately. I think that the part of the OS being monitored by the network would really only be the core software, the lines of code that interact with hardware.

    I chose this because I would like creativity and personalization to still be available for everyone. So this core OS that is being cryptographically secured would be like a protocol, a infrastructure that OS devs can use and build on top of. This also reduces the load on the nodes that already are constantly verifying an entire OS worth of code. I'm assuming that to mine the blockchain OS, the network would need a large amount of hashing power.

    Tl;dr: To summarize, I believe I may have just thought of a really cool use case of blockchain where the core components of an OS are being monitored for changes by nodes so that an entity, a government or a hacker, could not tamper with the OS's code without the entire network being made aware. There could also be some machine learning algorithms (I know buzz word lol) looking for malware installs. This would basically be a decentralized anti-virus built-in the OS. So there would be a coin to incentivize the nodes, the OS would be open source and the community would get to vote on proposals to improve the OS. I think this is a really cool idea.

    What do you guys think? I really want to try and grow this idea further. Thanks for your time.

    Why is this address spamming transactions?

    Posted: 19 Nov 2017 08:10 AM PST

    I, along with many others, are currently being spammed with 10 Erc20 token value transactions by the address 0x1240901c07EDD59902D76694886dB5D9ba0af1Fa. Anyone smarter than me know what's happening here?

    Does anyone know of a decentralised market place on the ethereum network like etherdelta

    Posted: 19 Nov 2017 01:59 PM PST

    Etherdelta love it, it works needs alot more work but its decentralised

    Anyone know of a project which is working on a decentralised market place like openbazaar but on the the ethereum network?

    Ethereum Vs. IOTA on microtransactions, which one do you think is better?

    Posted: 19 Nov 2017 04:44 AM PST

    I've read about the µRaiden framework but it needs to be used multiple times between users, so I still think IOTA's proposal is much better. Any thoughts?

    Upgraded to parity 1.8.2, UI stopped working

    Posted: 18 Nov 2017 09:51 PM PST

    Just upgraded and now can't run parity ui. I can get parity running in CLI though but the ui throws the error: Found argument '--can-restart' which wasn't expected, or isn't valid in this context

    Did the commands change? This is running in Debian.

    Buying ETH from Gemini

    Posted: 19 Nov 2017 01:29 AM PST

    Hello,

    I'm trying to claim an airdrop which requires I send something called GAS (500000) to a contract address, and I need to figure out how to get ETH. I have a Gemini account and was planning to buy a small amount of ETH. Does anyone happen to know the minimum withdraw amount?

    My apologies for such an annoying question.

    Looking to increase my wallet security while balancing backups

    Posted: 18 Nov 2017 08:25 PM PST

    Hi,

    I'm looking to improve the security of my ethereum wallet. Based on some reading, this is what I want to do...In general I am trying to balance security and keeping multiple backups (the latter of which I am more concerned about due to hardware failure etc)

    1.Generate a new wallet from offline MEW using a copy of ubuntu booted from a USB stick. Running off my main PC but with ethernet unplugged. Test with tiny transaction offline. 2.Once validated, transfer funds from current wallet to one above. 3.Only initiate transactions out of this wallet from the ubuntu live OS air gapped 4. (and here is where I'm not sure) put copies of my json wallet for backup purposes on my NAS (which is encrypted but is part of my home network of course) and on a USB stick in a fire safe. I know these files are encrypted with your passphrase, but I've heard concerns about brute force attacks or key logging generally knowing your password (which if I only unlock via MEW on my linux stick should be okay I think)
