    Why Decentralization? - The general public has no idea

    Posted: 27 Jan 2018 03:29 PM PST

    We need to do a better job helping people, and businesses, understand what decentralization is, when it is important and why it is important. Censor resistance. Protection from seizure. Why it benefits the good people.

    Any links to recommended resources?

    For those of you who speak at conferences, think about whether this is worth adding to your talks.

    I met Vitalik Buterin in a grocery store today.

    Posted: 27 Jan 2018 11:29 AM PST

    So I was doing grocery shopping - saw somebody who I thought looked like Vitalik. Then realized hey that is Vitalik.

    Approached him quietly and asked "Hi excuse me, are you Vitalik?"

    He turned away at first I think I scared him. Then I said I just wanted to meet him - at which point he said "oh ok sure" and we shook hands.

    I wanted a picture with him but he seemed much too timid so I didnt want to bother him and didnt ask for one.

    No real point to this other than it was a bit surreal to meet such a prominent figure in the crypto space. Figured I'd share.

    He's pretty tall. AMA.

    ELI5 - sharding on Ethereum (phase I)

    Posted: 27 Jan 2018 05:53 AM PST

    I've been reading the specification for sharding phase I: https://github.com/ethereum/sharding/blob/develop/docs/doc.md

    But, it's pretty complicated. Can someone describe in simple terms how it is expected to work?

    Much appreciated.

    Target addresses automatically switches before sending - is my MEW/Metamask compromised?

    Posted: 27 Jan 2018 06:04 PM PST

    I am trying to send an ERC-20 Token (ICX) from a metamask account to a Trezor through MEW and noticed something very odd. If I try sending ETH there are no issues however when I try sending ICX in the last step in Metamask with the "send" button the target address is switched to this wallet: https://etherscan.io/address/0xb5A5F22694352C15B00323844aD545ABb2B11028#code

    I noticed that it's actually a contract in the comments and that this has happened to other people resulting in them having lost their tokens. Is my metamask/MEW compromised or is something else causing this?

    Crypto community BOYCOTT

    Posted: 27 Jan 2018 09:22 AM PST

    Companies like Discover, Capital One, and other banks think they can flaunt their control over the financial system. The bravado flaunted over how much control they have over a system thats for the people is complete BS! Our money can be used for what we want as long as no laws are broken. If they think they can flex and surpress growth and adoption they're mistaken.

    MEW Newb question

    Posted: 27 Jan 2018 04:22 PM PST

    So I downloaded the offline version of myetherwallet and accessed it on a computer with no internet. While offline I generated a wallet and an address. I then went online and successfully sent some ether to the address.

    What I'm wondering is what if someone did the same thing as me at the same time on a different computer? Is there a chance that two people could generate the same private key and address using the offline version of MEW? What am I missing?

    'Download Parity for windows' link gives a file ethkey.exe that doesn't seem to match the checksum

    Posted: 27 Jan 2018 08:08 AM PST

    As mentioned in the title. The link on the page https://www.parity.io/ gives file ethkey.exe that doesn't seem to match the checksum 6689ca7bf1e9b2cd562c3bca9b655bd55967af14

    Can someone advise?

    edit: sha1 does produce the desired checksum so most likely all is ok. The use of sha1 threw me as their checksums on github are all sha256

    Decentralized Oracles, the truth & nothing but the truth.

    Posted: 27 Jan 2018 09:45 AM PST

    Just an idea...

    Basic premise:-

    On chain smart contract incentivizing Oracles to provide "truthful" data. Using Proof Of Stake to ensure consensus of the "truth".

    An example:-

    Alice & Bob disagree about the weather. Bob claims the temperature will be greater than 30 deg c, at a specific coordinate, on a specific day and hour. Alice insists it will be less than 30 deg c. They are so adamant, they enter into a wager using a weather oracle smart contract and wager 100 ETH each that they are correct. The contract is simple (sort of), winner takes all.

    Bob communicates his intent to the smart contract, something like

    IKnowHowHotItWillBe(100, >30, 2018-02-01T13:00:00 UTC, coordinate deg)

    Alice lists open wagers from the contract and sees bob's wager, she responds with.

    IKnowHowHotItWillBe(100, <=30, 2018-02-01T13:00:00 UTC, coordinate deg)

    The contract has several existing weather services "registered", which can provide weather information. This was transparent to both Bob and Alice at the time they submitted their wagers, listOracles(). Only these Oracles can provide information for this wager. It is, however, unknown to Bob & Alice which Oracles will publish results.

    The wager is fulfilled and ETH transfered to the lucky party, once all the oracles have responded. If less than x oracles respond within time (see below definition of time) bet is off. If greater than x oracles respond but not all oracles, the winner can still confirm wager after the time as expired.

    Each oracle publishes results with the following terms: - If they tell the truth, they are rewarded (x % of wager / total number of oracles) + transaction fees used. - If they lie, their stake is slashed x % of the wager and they are not refunded transaction fees. - They must submit their "truth" within 11520 blocks (~48hours) from the first block which has the selected time or they are slashed. - To tell the "truth" their results must be within y % variance of other oracles.

    The winner gets all ETH minus the Oracles fee and the Oracles transaction fees. The lying oracles stake is given to the winner.

    If gambling on the the weather is popular, then more users can enter into wagers and reduce the % given to oracles therefore reducing the cost of the truth.

    The devil is in the detail, which this post lacks lots of, my point here is more around how we can interact with the real world data reliably, without needing a single 3rd party service to act as a broker.

    blockie-picker: when when you want an address that looks good

    Posted: 27 Jan 2018 11:16 AM PST

    There was a thread the other day about the identicons shown in MyEtherWallet and Mist (and others), where someone made a comment about looking for an identicon they liked. I had recently refactored the identicon code out of [eth-button](), moving it to its own library.

    How hard could it be to build a simple site that does that?

    Not hard at all! Enjoy blockie-picker, an Ethereum vanity address generator that focuses on the identicon, not the address itself.

    I will update the README shortly, and can answer any questions here. It's a static site with no external (to the library) javascript, so it should be safe to use. However, if you do not want to run that risk, you can clone the repository, install the dependencies with npm install, and run the dev server with npm run dev. This will host the repository locally for you to use.

    [E] As always, comments, suggestions, bug reports, and pull requests are welcome

    autograph - batch process ERC20 token distribution - mini dapp

    Posted: 27 Jan 2018 12:11 PM PST

    I just launched a "mini"-dapp to batch process ERC20 token distribution from the browser. The code is very simple and is simply a minimal viable product. Just testing what it will take to easily send 10's, 100's or maybe even 1,000's of tokens in a couple of clicks.

    Code: https://github.com/KamesCG/autograph Demo: https://kamescg.github.io/autograph/#/

    Would be great if a couple of people could publish a RINKEBY wallet address, so I can test later this evening and send you my super "valuable" token called the "KCG" :)

    What does your Dapp workflow look like?

    Posted: 27 Jan 2018 09:17 AM PST

    The last post I could find about this was 2 years ago, and I know the ecosystem has changed a lot since then. I'm wondering what the development workflow looks like for your ethereum Dapp (technology/frameworks used, order of operation)? Hoping to get some insight into where the most support/documentation lies at the various touchpoints.
