Localethereum: Localbitcoins For Ethereum [eth P2p Market]
LocalEthereum: LocalBitcoins For Ethereum [ETH P2P Market] By: Sudhir Khatwani In: Ethereum Last Updated: P2P cryptocurrency markets are slowly and steadily getting attention. P2P markets and P2P crypto exchanges are a popular alternative to centralized exchanges. And why not? We know that centralized exchanges are prone to attacks and have been hacked time and again. And while P2P markets currently lack a lot of liquidity, they will certainly become a much stronger presence in the crypto world in the near future. These P2P markets open up a new possibility of buying/selling your favorite crypto directly in fiat, plus there are no headaches or frustrations around documentverifications/cancellations/etc. <br /> Can't load widget<br /> One of the biggest P2P exchanges is LocalBitcoins . But it currently only offers trading of Bitcoin . So thats why this new Ethereum P2P market sprang up. Its called LocalEthereum. ( Visit Website ) But its not just a LocalBitcoins clone; its actually implemented in a much better way. In this introduction of LocalEthereum, I will address the following points: LocalEthereum is a peer-to-peer ether portal that allows its users to swap ether (ETH) and fiat (USD, GBP, EUR, etc.) directly with other people, using end-to-end encryption and decentralized Ethereum-powered escrows . Through this platform, trading parties can trade in different ways via online bank transfers or online cash trades. While it is certainly not as old as LocalBitcoins , it is more secure because they are using Ethereum-powered smart contracts. The platform is currently available in English and Chinese. LocalEthereum just launched on 23rd October 2017 with more than 800 P2P offers of ether in 80 fiat currencies (however it had been in developme Continue reading >>
Ethereum Development Walkthrough (part 2: Truffle, Ganache, Geth Andmist)
Dapps, web, and games developer. Interested in AI, blockchain, and smart contracts. You can reach me at [email protected] or @dev_zl Ethereum Development Walkthrough (Part 2: Truffle, Ganache, Geth andMist) We have seen in the first part of this tutorial series what a smart contract is, and how it works. Now, we will deploy it to two kinds of test networks. The most prominent tools at the moments are: Truffle: A development environment, testing framework and asset pipeline for Ethereum. In other words, it helps you develop smart contracts, publish them, and test them, among other things. You can read the docs of the Truffle suite for more informations. Ganache: It was called TestRPC before, if you have read a tutorial from a few months ago, chances are they use TestRPC with Truffle, but it was renamed upon the integration of TestRPC within the Truffle Suite. What Ganache does is simple, it creates a virtual Ethereum blockchain, and it generates some fake accounts that we will use during development. Mist: Its a browser for decentralized web apps. It seeks to be the equivalent of Chrome or Firefox, but for Dapps. Its still insecure and you shouldnt use it with untrusted dapps as of yet. Ethereum wallet: Its a version of Mist, but only opens one single dapp, the Ethereum Wallet . Mist and Ethereum Wallet are just UI fronts. And we need a core that will connect us to an Ethereum blockchain(It could be the real Ethereum blockchain, or a test one). Geth: Is the core application on your computer that will connect you to a blockchain. It can also start a new one (in our case we will create a local test blockchain), create contract, mine ether etc. We will start by using Truffle and Ganache, and then use Truffle with geth and Mist. The requirements for this tutorial are that y Continue reading >>
How Do I Get Some Ether Or Ethereum?
There are a few ways to buy Ethereum, Ether or ETH (it's trading ticker name), and this guide is going to show you how you can get hold of some in the easiest way possible. Just like Bitcoin there can be quite a few cumbersome hoops to jump through but hopefully we can show you the best method to suite yourself. You can buy it with fiat currency, buy it with bitcoin or you can mine it. There are a number of fiat exchanges that you can use to buy ethereum, or ether, directly with local fiat currency such as dollars euros or yuan. Kraken is a particularly good way to buy ethereum with dollars, pounds or euros and we've written a guide on that here . There are other exchange that you can use to get hold of ethereum immediately. All you need to do is go to the page here and find out which exchange trades into your local currency by clicking on the tabs on the right hand side. If you can't find the right currency to trade into or you think the bid ask spread is too high or there isn't enough liquidity you will have to buy it another way. The best way to do this is to buy bitcoin first. One of the least hassle ways to buy bitcoin is to use Coinbase. Unfortunately Coinbase is only supported in a few countries and their pay by debit card feature is limited to a certain quantity per day. There are other exchanges you can use and you can find them out by doing exactly the same check as you have done on the ethereum page. Once you have found the right place to buy some bitcoin.... buy some. There are some loopholes to go through usually that can make the process painful, but that is only Companies trying to comply with legislation on KYC and AML. Now you have bitcoin you can get ETH or ether by using one of the exchanges that operates a BTC-ETH pair. They can be found here . Anot Continue reading >>
Ethereum Price Achieves New All-time High At $518, Cryptokitties Effect?
Ethereum Price Achieves New All-Time High at $518, CryptoKitties Effect? Join our community of 10 000 traders on Hacked.com for just $39 per month. Ethereum price has achieved a new all-time high at $518, surpassing its previous all-time high established on November 29, at $514. According to leading cryptocurrency market data providers CryptoCompare and CoinMarketCap, the vast majority of recent trades were processed in the US cryptocurrency and Ethereum exchange markets. Currently, the US market accounts for more than 33.71 percent of global bitcoin trades. For many months, the South Korean market remained as the leading Ethereum exchange market, often accounting for at least 30 percent of global Ethereum trades. Recently however, the US market overtook the South Korean market, with GDAX, the flagship cryptocurrency exchange of Coinbase, processing most of the Ethereum trades in the global market. From September to the end of November, the price of Ether has not made major movements, mostly because the impact the ban on initial coin offerings (ICOs) by the Chinese government had on the local Ethereum market and the rapid increase in the value of bitcoin. In early December, the price of Ether started to record small gains, triggered by the communitys excitement on the developer activities around the Ethereum blockchain network. Most recently, Ethereum-based decentralized application (dapp) CryptoKitties gained massive success. The smart contract of CryptoKitties has accounted for nearly 14 percent of the entire Ethereum networks transaction volume, which is higher than the transaction volume of all other cryptocurrencies in the market combined, including bitcoin. While many members of the cryptocurrency community dismissed CryptoKitties as a simple collectibles-based g Continue reading >>
Best Ethereum Exchange Review And Comparison
You are at: Home Best Ethereum Exchange Review and Comparison Best Ethereum Exchange Review and Comparison As Ethereum becomes more and more popular it seems like its getting harder to find the best exchange for buying some Ether (the Ethereum currency). In this article Im going to go over the different Ethereum Exchanges available and list the various things you need to take into account before choosing an exchange. Trading platforms Connect buyers and sellers automaticallythrough an online website. The buyer states the requested price and the platform finds a seller that meets the bid. No direct communication is done between the buyer and seller. Trading platforms are usually the cheapest option when it comes to fees but are also much more complicated than the other options. Brokers A website that sells you Bitcoin directly for a premium. Brokers are usually the easiestway to buy Ethereum but are also more expensive. p2p platforms Websites that connect buyers and seller directly so they can negotiate on a price. While this sites usually allow for a wider array of options (payment methods, supported countries, etc.) they also hold a large amount of risk since youre buying from an anonymous individual. Heres a list of the best Ethereum exchanges available today. When examining an exchange you should usually take into account several factors such as: Coinbase is the most popular method today for buying Ethereum.

Local Ethereum Completes 100 Otc Exchanges. Whats The Future Of Decentralized Applications?
Decentralized applications and trading platforms are gradually gaining traction in the global cryptocurrency market. This week, two days since its debut, peer-to-peer (P2P) Ether marketplace LocalEthereum completed nearly 100 over-the-counter (OTC) Ether trades. In its first two days, localethereum helped traders complete nearly 100 over-the-counter exchanges worth a total of ~$US60,000. While this number looks slim next to high-frequency exchanges, its a terrific start and the trading volume continues to grow rapidly as more jump on board, revealed the LocalEthereum development team. The Benefits of Decentralized Exchanges and Protocols As noted by experts such as Coinbase co-founder and former Goldman Sachs trader Fred Ehrsam, decentralized exchanges are particularly useful for circumventing impractical anti-money laundering (AML) and Know Your Customer (KYC) policies, as well as increasing security measures for their users. By nature, hackers cannot target decentralized applicationslike EtherDelta and LocalEthereum whichoperate usingpublic blockchain networks because they do not rely on third-party service providers or intermediaries. Governments cannot possibly demand data from EtherDelta and LocalEthereum due to their decentralized structures and non-custodial platforms. Apart from their significant improvement in privacy, decentralized exchanges provide maximum security for users, as private keys and sensitive information of traders are not stored or managed by the platform and its developers. Instead, users have full control over their private keys and funds, preventing the possibility of security breaches and theft of funds. Fred Ehrsam summarised some of the benefits of decentralized exchanges in a recent Medium post : There are a few obvious benefits to decen Continue reading >>

Howto: Set Up An Ethereum Private Local Testnet
Crypto, Products, and other Random Thoughts HowTo: Set up an Ethereum private local testnet howto blockchain ethereum guide osx crypto Ethereum is a decentralized blockchain platform for smart contracts. The protocol is designed in such a way that we can run Turing-complete (arbitrary length) applications. In this guide, we will go over how to set up our own private local testnet (Mac OS X). Questions, comments, and suggestions for improvements are always welcome. Anything published on the Ethereum public mainnet is immutable and consumes gas (Ether) to execute, which can be costly for testing purposes. Having our own Ethereum testnet allows us to test any smart contracts before we deploy it to either a public testnet or the public mainnet, which means we can catch as many errors as possible. It also happens to be a great learning experience. Guides already exist but are outdated or incomplete From my research there are three guides that seem to be the most authoritative and useful on setting up a testnet, listed below in #References . If we combine together the three guides and a few of the StackExchange solutions, then we arrive at this guide. There's lots to learn in this post. To help you remember, try my app Harvest : Take Notes and Learn Passively. You can write or highlight any notes, save them, and automatically receive reminders on an optimal learning schedule. There are a few steps we have to do first to get the necessary tooling. The easiest way to get set up with the Go implementation of Ethereum (the most popular and well-supported) is to use Mac's official unofficial package manager brew: brew updatebrew upgradebrew tap ethereum/ethereumbrew install ethereum Most of us will be running this on our laptops. Since disk space (?) and bandwidth are probably at Continue reading >>

Keep in mind that when trading CFDs your capital is at risk. Lately there has been a lot of talk about the hottestaltcoin in the community Ethereum. Ethereum is a cryptocurrency and a blockchain platform with smart contract functionality. Its basically a decentralized platform for developers to build apps on top of and it was invented by Vitalik Buterin in 2013. Ethereum can be used to codify, decentralized, secure and trade just about anything: voting, domain names, financial exchanges, crowdfunding, company governance, contracts and agreements of most kind, intellectual property. Well, Ether is the currency of the Etherium platform. Etherwill be required by anyone wishing to build upon oruse the Ethereum platform. Just like BItcoin, Ether can be traded around the web and mined. In a second Ill show you exactly where you can buy it. Most people use the term Ethereum to refer to the currency instead of Ether and thats why it can get so confusing. The total supply of ether and its rate of issuance was decided by the donations gathered on the 2014 presale of the currency. The results were roughly: 60 million ether created to contributors of the presale 12 Million (20% of the above) were created to the development fund, most of it going to early contributors and developers and the remaining to the Ethereum Foundation 5 ethers are created every block (roughly 15-17 seconds) to the miner of the block 2-3 ethers are sometimes sent to another miner if they were also able to find a solution but his block wasnt included (called uncle/aunt reward) The founders of Ethereum state that Ether is not a currency as much Continue reading >>
Blockchain - How To Connect To Geth From Two Local Machines Ethereum - Ethereum Stack Exchange
how to connect to geth from two local machines ethereum I am new to Ethereum and tried everything to connect testnet from two local machine nodes.i tried with running two consoles in single machine by admin.addPeers(nodeUrl) and could connect. when i tried with the same for different machines using same network id it is showing peer count as zero.please help to solve this. thanks in advance Since you're running two nodes on two different machines, you need to mention the IP address of the node while connecting through addPeer(enodeURI). You need to have the same genesis file in every machine you wish to start a node. All the nodes should have the same --networkid The --rpcport and --port should be different for every geth instance. If working on the same machine, each geth instance should have different --datadir. geth --genesis path/to/genesis.json --datadir path/to/directory --networkid 1234 --port 30301 --rpcport 8101 console geth --genesis path/to/genesis.json --datadir path/to/directory --networkid 1234 --port 30302 --rpcport 8102 console You might add commands like --maxpeers and --nodiscover if you wish. After starting these instances, check for a similar message on the console: I0829 13:30:07.347738 3987 backend.go:303] Successfully wrote genesis block. New genesis hash = 82b6159155c00fb0b420046012a02257a176ad5dcfce4be4a15da39c166518e2 If this is the case, you successfully started the nodes with a private blockchain. If you see a message similar to Warning: Wrote default ethereum genesis block, then there's something wrong. "enode://da97197a3335806658f17fdc167e943bd040fdf59ed882389d5f87b29f31362b1[email protected][::]:30301" Observe that the port number in the end of URI is 30301.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. Are you looking for the Remix IDE? Follow this link ! Remix is a suite of tools to interact with the Ethereum blockchain in order to debug transactions, stored in this Git repository. A Remix transaction Web debugger is available here , and its source code is part of this repository. The Remix IDE is an IDE for Solidity dApp developers, powered by Remix. The Remix IDE repository is available here , and an online version is available at . For more, check out the Remix documentation on ReadTheDocs . To use Remix tools, you'll need to connect to an Ethereum node. You can do that using the Mist browser , or by connecting to your local Ethereum node (geth, or eth). Note: connecting to geth does not work through https. Using geth: geth --rpc --rpcapi 'web3,eth,debug' --rpcport 8545 --rpccorsdomain '*'. DO NOT DO EXECUTE THESE COMMANDS IF geth/eth STORES YOUR PRIVATE KEYS, as any external system might be able to access your node's RPC server! Those commands will run the RPC server on localhost:8545, which is the default URL that Remix will connect to. This instance should only be used for debugging purposes. Never use features that could have an impact on your keys: do not unlock any keys, do not use this instance together with the wallet, do not activate the admin web3 API. See here how to install, run and use the debugger locally. The debugger itself contains several controls that allow stepping over the trace and seeing the current state of a selected step.
