Heres how we buy Ethers and Bitcoins . You will receive $10 of FREE BITCOIN when you buy or sell over $100 worth of any digital currency. Ethereum is more than yet another cryptocurrency. Its a decentralized, blockchain-based distributed computing platform capable of running smart contracts. Its the support for smart contracts that makes many believe that Ethereum will soon overtake Bitcoins. Smart contracts data back to the 90s, but their practical implementation has been made possible thanks to the blockchain technology, a distributed database that is used to maintain a continuously growing list of records in a way thats inherently resistant to modification of the data. With smart contracts, its possible to program the terms of the contract between buyer and seller to facilitate, verify, and enforce the performance of a contract. [Smart contracts] run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference, explains the official website of Ethereum. Because the execution of smart contracts requires computational power which someone must provide, the instructions embedded in Ethereum contracts are paid for in Ether. Consequently, those who own a lot of Ether can pay for a lot of smart contracts. If smart contracts really become the future Continue reading >>

How to create your own ethereum wallet. Paper wallet, mobile ethereum wallets, web wallets, desktop wallets, hardware wallets. Before you can trade Ether, you need a place to store it. In the cryptocurrency world, that place is called a wallet. Essentially, it is a piece of software that allows you to store your funds, easily conduct transactions and check your balance whenever you need to. It is worth noting that Ethereum wallets work nothing like conventional physical wallets do. Ether is actually is not stored in your wallet, or anywhere else for that matter. Ether, just like every other cryptocurrency, doesnt exist in any tangible shape or form. All that exists are records on the Blockchain, and your wallet will only interact with the Blockchain to enable transactions. Read more: How Blockchain Technology Works Wallets have public addresses, which are randomly generated strings of case-sensitive letters and numbers. If someone wants to send you some Ether, they will send it to this address, which is also referred to as a public key, essentially transferring the ownership of the coins. What is stored ins your wallet, is your private key, a password that you will need to sign off on transactions and unlock coins shared to you. It goes without saying that your private key has to be kept a secret if you would like to avoid theft of your Ether. The public and private keys are paired, which means that in order for you to perform any trans Continue reading >>

How Ethereum Works On Luno

How Ethereum Works On Luno

Luno recently added support for the Ethereum blockchain, allowing South Africans to buy and sell in rand. The company also added an Ethereum wallet to its cryptocurrency storage portal, meaning users can send and receive Ethereum to and from other Ethereum addresses. MyBroadband spoke to Luno about the features and limitations of its Ethereum service, and whether it will expand its Ethereum support in the future. Luno is primarily a cryptocurrency-to-fiat exchange, and like most exchanges, its Ethereum wallet does not support ERC20 tokens. Many cryptocurrencies which are built on Ethereum, such as OMG and Augur, can be sent to an Ethereum address and accessed from supported wallet software. As Luno users do not hold their own private keys, they will not be able to recover ERC20 tokens even if they download a standalone wallet client. If someone wants to participate in a token sale, they should send their ETH from Luno to an ERC20 compatible wallet, said Lunos Werner van Rooyen. Customers should also not send any unsupported currencies or ICO tokens to their Luno account. Users who want to add an Ethereum wallet to their Luno account must: Access their Luno menu, and select Wallets. Lunos Ethereum wallet service functions on the same architecture as its Bitcoin wallets. This means that user private keys and funds are stored in cold wallets, with a certain amount of funds circulated in exchange-operated hot wallets. While this is a secure way to prevent customers private keys from being compromised, it also means users do not officially own their cryptocurrency. Instead, Luno owns the private keys and holds the cryptocurrency on the users behalf. Van Rooyen told MyBroadband that the Luno exchange has become increasingly popular throughout the year, with around 738 Bitcoi Continue reading >>

Last updated on November 24th, 2017 at 08:15 am Ethereum, the blockchain platform that allows smart contracts, is becoming more and more popular.Since the beginning of 2017 the price has spiked from $8.22 to around $50. Ive covered how to buy Ethereum in a previous post but thats only part of the process. Today I want to cover 5different types of Ethereum wallets so you will know where to store your Ethereum. Ethereum is a very technical currency (even more than Bitcoin), therefore most wallets out there arent newbie friendly. I will go over them from the simplest to the most complex so you can choose the one that is best suited to your knowledge level. Hardware wallets Best security (for a price) If youre serious about securing your altcoins I suggest storing your Ethereum on a hardware wallet. However these hardware wallets arent free and cost anywhere between $50-$100 (shipping not included). Todays leading hardware wallets TREZOR , Ledger and KeepKey all supply you with the option to store Ethereum on them. Instead of explaining about each one Ill just link to my previous reviews on the wallets: Personally, I use a TREZOR but all three are excellent choices for maximum security. Coinbases Ethereum wallet The simplest option Coinbase supplies an Ethereum wallet as well as a Bitcoin wallet. Coinbases wallet is simple to set up and very easy to use, however it has a few limitations youll need to be aware of: The company holds the private key ofthe wallet for you. This means youre not in control of your funds and Coinbase can decide to shut down your account if they want to. There were cases in the past that Coinbase shut down user accounts do to illegal activity. The Coinbase ETH wallet doesnt support ETC (Ethereum Classic). For a simple explanation about ETC vs ETH r Continue reading >>

CoinDesk Launches 2017 Year in Review Opinion and Analysis Series Now that we've covered what ethereum is, let's dive deeper into how the platform functions under the hood. Consider the online notebook application described in " What is Ethereum? " Using ethereum, the appdoesn't require one entityto store and control its data. To accomplish this, ethereum borrows heavily from bitcoin's protocol and its blockchain design, but tweaks it to support applications beyond money. Ethereum aims to abstract away bitcoin's design, however, so that developers can create applications or agreements that have additional steps, new rules of ownership, alternative transaction formats or different ways to transfer state. The goal of ethereum's 'Turing-complete' programming language is to allow developers to write more programs in which blockchain transactions could govern and automate specific outcomes. This flexibility is perhaps ethereum's primary innovation, as explained in the guide " How Ethereum Smart Contracts Work ". The structure of the ethereum blockchain is very similar to bitcoin's, in that it is a shared record of the entire transaction history. Every node on the network stores a copy of this history. The big difference withethereum is that its nodes store the most recent state of each smart contract, in addition to all of the ether transactions. (This is much more complicated than described, but the text below should help you get your feet wet.) For each ethereum application, the network needs to keep track of the 'state', or the current information of all of these applications, including each user's balance, all the smart contract code and where it's all stored. Bitcoin uses unspent transaction outputs to track who has how muchbitcoin. While it sounds more complex, the id Continue reading >>

What Is Ether?

What Is Ether?

Ether is a necessary element a fuel for operating the distributed application platform Ethereum. It is a form of payment made by the clients of the platform to the machines executing the requested operations. To put it another way, ether is the incentive ensuring that developers write quality applications (wasteful code costs more), and that the network remains healthy (people are compensated for their contributed resources). If you just want to test the technology, you probably don't need real ether. Download the latest Wallet app and switch to the Test Network Check your ether presale balance safely here: The total supply of ether and its rate of issuance was decided by the donations gathered on the 2014 presale. 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 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 wasn't included (called uncle/aunt reward) Note that after the Byzantium update is implemented, the mining and uncle reward is reduced to 3 ethers and 0.625-2.625 ethers, respectively. No. According to the terms agreed by all parties on the 2014 presale, issuance of ether is capped at 18 million ether per year (this number equals 25% of the initial supply). This means that while the absolute issuance is fixed, the relative inflation is decreased every year. In theory if this issuance was kept indefinitely then at some point the rate of new tokens created every year would reach the average amount lost yearly (by misuse, accidental key Continue reading >>

Cryptocurrency Wallet Guide: A Step-by-step Tutorial

Cryptocurrency Wallet Guide: A Step-By-Step Tutorial Angel Investors, Startups & Blockchain developers... Use this straightforward guide to learn what a cryptocurrency wallet is, how they work and discover which ones are the best on the market. A cryptocurrency wallet is a software program that stores private and public keys and interacts with various blockchain to enable users to send and receive digital currency and monitor their balance. If you want to use Bitcoin or any other cryptocurrency , you will need to have a digital wallet. Millions of people use cryptocurrency wallets, but there is considerable misunderstanding about how they work. Unlike traditional ‘pocket’ wallets, digital wallets don’t store currency. In fact, currencies don’t get stored in any single location or exist anywhere in any physical form. All that exists are records of transactions stored on the blockchain . Cryptocurrency wallets are software programs that store your public and private keys and interface with various blockchain so users can monitor their balance, send money and conduct other operations. When a person sends you bitcoins or any other type of digital currency, they are essentially signing off ownership of the coins to your wallet’s address. To be able to spend those coins and unlock the funds, the private key stored in your wallet must match the public address the currency is assigned to. If public and private keys match, the balance in your digital wallet will increase, and the senders will decrease accordingly. There is no actual exchange of real coins. The transaction is signified merely by a transaction record on the blockchain and a change in balance in your cryptocurrency wallet. What are the different types of Cryptocurrencywallets? There are several types of Continue reading >>

Ethereum Wallets: Short & Simple Guide To Storing Ether Ethereumprice

Ethereum Wallets: Short & Simple Guide To Storing Ether Ethereumprice

As Ethereum moves closer to main stream adoption, Ethereum wallet engineers are hard at work improving the usability of their products. Despite this, managing Ethereum transactions and security of a users private key is not for a technophobe. Those who would prefer to avoid the risks associated with security may wish to use a 3rd party exchange to store Ether; you can read about this in our how to buy Ethereum guide. Those who want to take absolute control over their own Ether should read on. The Ethereum blockchain is a shared history of every transaction ever to occur on the network. All balances are public but pseudonymous (displaying your identity is strictly opt-in) and all transactions are relayed by every node. Nodes play an important role in ensuring that transactions are valid, and transactions which arent valid are simply rejected from the network. Ethereum wallets remove the complexities of forming and broadcasting valid transactions described above. Instead, they simply ask the user which address they wish to send their funds to, similar to how one may send a payment via an online bank transfer. When a transaction is sent, the information about that transaction is propagated across the network and then validated by the many thousands of Ethereum nodes in the network. Miners then include valid transactions in the next block mining 1 block roughly every 15 seconds. Ethereum mining will be discussed in a separate article, however the important thing to note when it comes to wallets is that a transaction needs to be included in a block before it can be considered to have been sent. Most merchants will also require that an additional 20 blocks or more are mined on top of the block that the transaction was included in as a means to ensure its finality. For reason Continue reading >>

Unzip it and double-click index.html. This should open MyEtherWallet in your browser. Note: do not move files around in this folder. You need the entire folder for it to work correctly. Enter a strong but easy to remember password. Do not forget it. This encrypts (protects) your private key. It does not generate your private key. This password alone will not be enough to access your Ether. Download your Keystore / UTC file & save this file to a USB drive. This is the encrypted version of your private key. You need the password to access it. It is safer than your unencrypted private key but you must have your password to access it in the future. Read the warning. If you understand it, click the "I understand. Continue" button. Print your paper wallet backup and/or carefully hand-write the private key on a piece of paper. If you are writing it, it is recommend you write it 2 or 3 times. This decreases the chance your messy handwriting will prevent you from accessing your wallet later. Copy & paste your address into a text document somewhere. Get it to your primary, online computer. Use the QR code or a different USB drive. It is best if you do not hand-write it Search your address on . Bookmark this page. This is how you will view your balance at any time Send a small amount of Ether (0.0001 ETH) from an exchange or another wallet to your new offline wallet.

How Ethereum Wallets Work And How To Back Them Up

How Ethereum Wallets Work And How To Back Them Up

How Ethereum wallets work and how to back them up If you've used bitcoin wallets and backed them up yourself, they work in the same way, so if you're coming from that background, you probably don't need to read this article. This is for people that are learning about Ethereum as their first cryptocurrency and want to understand a little more about how to properly store their coins with as little technical detail to get lost in as possible. As someone completely new to blockchains, you might not know how your ether is actually stored. I myself as someone that didn't know anything about bitcoin before I started learning about Ethereum know how this feels. You might think you have actual digital coins stored on your computer. You may have heard that you need to back up your wallet - does that mean I'm duplicating coins? You might think that your password is enough to get back your coins. That's not how it works. To understand how your coins are stored and accessed, you need to understand a little bit about public/private key encryption. If you've ever used SSH keys before, it's similar. You have a pair of keys that are randomly generated (usually by your wallet application). The public key in ethereum is the address you give to other people to send money to your account. The private key is hidden away behind password encryption, and is the key that proves to the network you are who you say you are. The 'wallet' that you are storing is actually just the private key and as long as you have that, you can access your coins. The reason why it is password protected is so if someone manages to get access to your private key, they still need to crack your password to get access to your account. The way that Ethereum stores coins, is on the blockchain, it has a record of how much Continue reading >>

(This page covers an older version: Version 0.3.8, Beta 5. For a more recent version, select from the menu.) Versions of the Wallet App are available for Linux, Mac OS X, and Windows. For the Wallet App to work, it will need to connect with a running, fully synced Ethereum node. The Mac, Linux 64Bit and Windows 64Bit versions come with a bundled Ethereum node, the Golang implementation called Geth. As this user guide is targeted at non-technical users who will not want to separately install a Geth node, only these versions with the bundled node are covered in this guide. Note: The Mac OS X and Win 64Bit versions also include Eth, the C++ Ethereum client. However, only Geth is covered here. Downloading the Wallet App involves syncing a full copy of the Ethereum blockchain on your computer, requiring almost 6 GB of disk space as of early January, 2016. As such, be prepared to wait about an hour for the initial syncing process to complete. Note: In this example, I work through the installation of the Win 64Bit version. Select the version you require from the available options on this page . For this example, I select: Ethereum-Wallet-win64-0-3-8.zip After you unzip the downloaded folder, look for and launch the Ethereum-Wallet application/program file. When the blockchain has fully synced, you will see the Wallet Apps sparse (but beautiful!) opening screen: Note: If you previously downloaded and used a version of this Wallet App, you may see one or more Accounts displayed in the opening screen. This is because, when you update the Wallet App by downloading a new version, the app will continue to use data from the older version. More on this later. Most Wallet App operations will fail if your node is not fully synced, that is, if your copy of the blockchain is not up-to-da Continue reading >>
