    Buy laptop with ETH

    Posted: 25 Aug 2019 03:42 PM PDT

    Hey all where is the best place to buy something with ETH. I would like to avoid converting into BTC or another currency. I'm looking to buy some camera gear and a MacBook. Trusted recommendations?

    Gas problems

    Posted: 25 Aug 2019 01:25 PM PDT

    No, not like farting. I just spent 41 Gwei in order to get a transaction through. Though https://ethgasstation.info/ says 6 gwei should be more than enough.

    I also tried to send ETH via Atomic wallet and it would never go through as its always too less gas.

    Am i missing something? I feel like i don't get parts of the whole transaction system of ETH

    ​

    Thanks

    What is an “Ethereum Community”?

    Posted: 25 Aug 2019 07:43 AM PDT

    I was recently asked a few interesting questions, which I found difficult to respond to properly:

    • What are you favorite "Ethereum Communities"?

    This led me to question what an 'Ethereum community' really is. Not only do I not personally have a clear definition of a community — concerning one that organizes around a decentralized network, but it's not always clear how or why these communities form.

    For example, MetaCartel. This is an organized, but relatively obscure community of individuals that gathered due to a shared interest in meta-transactions.

    • What are some of your favorite 'Ethereum Communities'?

    • How do these communities form and find each other, to then self-organize?

    • At what point do we draw the line between a 'community' and a 'project'? (E.g., EthMagicians is a community.. but I'd consider Kyber to be more of a project than a community).

    My apologies — I know that this post ended up as more of a brainstorm with questions scattered throughout. But I'd be interested to see what the larger 'Ethereum Community' here perceives as notable, smaller 'ETH Communities' — and perhaps a story about how you found your favorite community relating to the Ethereum ecosystem.

    Is it always safe to broadcast a signed raw transaction that I've manually reviewed?

    Posted: 25 Aug 2019 05:10 AM PDT

    I've been playing around with MyEtherWallet, downloading it and running it in offline mode. Using some throw-away addresses, I created the following raw signed transaction:

    { "rawTransaction": "0xf86b808398968082520894e37962ffcebb3d6960e7b32c65fa112b0b314db189055de6a779bbac00008026a0d4f5fcf8a0a59253e3ee8a71dc2b61501ad948db45aabd7c2d081550fe75bb8ba01cfb0d01dc1555c970008674955d12111bb940265c2ffcc231ebea3fe2215e2b", "tx": { "nonce":"0x00", "gasPrice":"0x989680", "gas":"0x5208", "to":"0xe37962ffcebb3d6960e7b32c65fa112b0b314db1", "value":"55de6a779bbac0000", "input":"0x", "v":"0x26", "r":"0xd4f5fcf8a0a59253e3ee8a71dc2b61501ad948db45aabd7c2d081550fe75bb8b", "s":"0x1cfb0d01dc1555c970008674955d12111bb940265c2ffcc231ebea3fe2215e2b", "hash":"0x3cd65a22422de63e977e810a559c08afb3a9f351e14c1d72fbda54809fa2e202", "gasLimit":"0x5208", "data":"0x", "chainId":1 } }

    What I tried to do was to send 99 ETH from 0x8fA00A959Bbb72B4b6F25fB8B7B36c4085Bb83E1 to 0xe37962ffcebb3d6960e7b32c65fa112b0b314db1.

    Now, if all people behind MyEtherWallet were crocks (let's say they've been brainwashed by evil space lizards), would I still be safe trying to broadcast this transaction via MyEtherWallet in online mode? That is, is this whole JSON file sent to the network where all the values have to agree with each other? I realize that the transaction could be rejected if done erroneously, but is there some way, if MyEtherWallet controls both the online and the offline wallets, that the final transaction could be something else than I thought (given that I don't make any mistakes when reviewing the raw signed transaction above)?

    In addition, when looking at the JSON above, I can't find neither the output address (0x8fA00A959Bbb72B4b6F25fB8B7B36c4085Bb83E1) nor the amount (99 ETH). Is it possible to see these somehow?

    Which Ethereum wallet do you use/should I use?

    Posted: 25 Aug 2019 11:30 AM PDT

    Ethereum recommends some web based wallets or firefox extensions. But those seem scetchy to me.

    Is Smart Contracts a Failure?

    Posted: 25 Aug 2019 04:29 AM PDT

    Welcome to Bitcoinland. If you imagine me as a troglodyte from the Internet - you are probably right.

    As you know, there's RootStock on Bitcoin, which is a smart contract compatible with Ethereum. Although the project is in a very preliminary phase, I started to think about the idea of smart contracts.

    Personally I would divide (initially) Smart contracts into 4 groups

    * Projects that support the Ethereum as a currency. Such as Zk-Snarks, Raiden etc. or by Ethereum as Bitcoin is a means of payment. Here, smart contracts make sense, but they're half-hearted. They support Ethereum, but probably not in the sense of the idea of Smart Contracts (unstoppable applications).
    * ICO / DAO - projects that are created on a speculative bubble. Most of them die, most of them are created on the basis of the same code.
    * Casino (and maybe games)
    * Other applications like DeFi

    Of course, I'll point out here, I don't follow projects at Ethereum. Maybe it is a great technology, and I omitted a lot of important things. I tried to find out from other colleagues who have Ethereum what is cool, but I guess they do not know exactly.

    DEX. Personally, I am a fan of decentralised exchanges, systems that will allow to develop cryptocurrency technology by eliminating intermediaries who get hacked or steal money. I am a fan of e.g. Bisq, where I can (hypothetically at least) buy cryptocurrency with fiats or other crypto.

    However, many ETH exchanges do not allow this. They allow ETHs to be exchanged for other tokens on ERC20 and vice versa. No wonder, because it is much easier to do (probably than creating contracts that verify transactions on other crypto). It seems to me that here Ethereum solves a problem that he created himself.

    There's a lot about loans on Ethereum (or DAI) lately. At first I thought - Wow, this is very good news.

    However, from what I understood, these are loans to speculate on money more (??). As an example of application I got such a thing:

    - You want to borrow 1000 DAI (for example)
    - You deposit 1050 DAI (You must deposit more than you borrow, because commissions + motivation to repay the loan).
    - You exchange (for DEX?:P) DAI for Ethereum.
    - Ethereum to the moon
    - You sell Ethereum (part of it at least) and repay the loan by recovering e.g. 1040 DAI, and at the same time you are richer with Ethereum.

    If you fail, the money goes to cover the debt.

    I do not see a consumer application here. It's not worth buying a house or a computer if I need more money than I want to borrow. Here it is better to create a system of "social" loans, which are risky but cheaper at the same time?

    My question is, are there any interesting solutions for which Smart contracts are suitable? Do they really compete with centralized solutions and solve big problems? I'd write that maybe it's technology overhype, but somebody could kill me.
