How Ethereum Works - Coindesk

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 >>

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 >>

How To Make A Paper Ethereum Wallet

How To Make A Paper Ethereum Wallet

Oliver Dale on November 2, 2017 / 0 Comments It is highly recommended to create an Ethereum paper wallet as one of the safest methods of securing your cryptocurrency. Essentially, an Ether paper wallet is a record of your Ethereum Wallets Private and Public keys which you need to access your wallet and make transactions. Possessing a piece of paper with a code on it and calling it a wallet may come off as a little weird to some. However, it is the safest method you can employ to store your precious Ether coins. Paper wallets provide an extraordinary advantage over other conventional cryptocurrency storage techniques. Imagine the comfort you will feel knowing that your Ether can be stored safely in your house, deposit box, or safe or even buried in your backyard. Advantageously, the paper wallet isnt part of the internet. Therefore, no hacker can ever gain access to your precious cryptocurrencies. A potential thief would have to crack your safe or dig through your whole backyard to find your wallet and cryptocurrency information. A Paper wallet is perfect for people who wish to keep their Ether in cold-storage that is, un-connected from the internet and safely stored away. With a paper wallet the speed for transfers and exchanges, as well as the overall speed at which your Ether becomes available, is greatly reduced. This is due to the coins having to be relayed back to an online wallet before they can be utilized. If you wish to use your Ether at am exchange or for speculation purposes to make some money and benefit from market price fluctuations, then your Ether always has to be readily available. For those purposes, an online wallet is recommended, at least for the sake of efficiency. However, if you plan on sticking with your Ether for the long run by being a Hodler Continue reading >>

Best Ethereum Wallet (2018 Update) 5 Options Reviewed

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 >>

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.

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 >>

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 >>

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 >>
