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 Ethereum? What Is Ethereum Mining & How Does It Work?

What is Ethereum? What is Ethereum Mining? Jordan Tuwiner Last updated July 13, 2017 Ethereum is more than a cryptocurrency. Its an open source shared world computing platform. A world computer that allows for the decentralized verification of transactions for any Turing-viable implementation. Thanks to Ethereum, Blockchain technologies are now easy to employ without having to reinvent the wheel. It is clear that Ethereum grew out of desire to apply Bitcoin/Blockchain concepts to realms outside of money. As a result, it provides open source platform to developers who seek to write decentralized applications. This appeals to developers who seek an easy introduction to Blockchain projects A series of innovative features definite Ethereum. As a result of its extended capabilities, Ethereum comes with two types of accounts . EOA, or Externally Owned Accounts, provide bitcoin-like capabilities such as providing a balance that is secured by private keys. Contract Accounts provide the Turing Complete room for application development that makes the protocol so desirable. These accounts are used as holding objects to constitute Smart-contracts which provide Ethereums capability for accommodating decentralized autonomous organizations; a way of structuring organizations without a vulnerable center. Most importantly, Ethereum capitalizes on the realization that consensus allows for currency and currency allows for consensus by providing economic incentive. As such, verifications are paid for on a pay-per-use basis, a system that replaces mining as we know it from Bitcoin. Ethereum right now uses PoW mining to secure its chain. Vitalik Buterin, the creator of Ethereum, stressed that his idea was fueled by the desire to [Avoid] the swiss-army knife protocol . That is to say that us Continue reading >>

Ethereum Mining 101: Your Complete Guide

Ethereum Mining 101: Your Complete Guide

The world has gone digital, from the development of smart homes to the development of innovations that promote seamless transactions. Every industry is feeling the impact of technology now more than ever. In every part of the world, the technologically driven goals remain the same: the maximization of profit and the promotion of sustainable development in all spheres of life. It is this yearning to make life as easy as possible that brought about the birth of cryptocurrency . Ethereum seeks to make these aspirations come true. The platform boasts of several applications that help users carry out everyday tasks in a simple fashion. What is Mining, Ethereum Mining and Where Does Ether Come From? Mining is a computationally intensive work that requires a lot of processing power and time. Mining is the act of participating in a given peer distributed cryptocurrency network in consensus. The miner is subsequently rewarded for providing solutions to challenging math problems. It is done by putting the computer's hardware to use with mining applications. All the information on cryptocurrency transactions must be embedded in data blocks. Each block is linked internally to several other blocks. This creates the blockchain . These blocks must be analyzed as fast as possible to ensure a smooth running of transactions on the platform. However, the issuers of such currencies do not have the processing capabilities to handle this alone. It is where miners come in. A miner is an investor that devotes time, computer space and energy to sorting through blocks. When the mining process hits the right harsh, they will submit their solutions to the issuer. After verification, the issuer of the currency offers rewards which are portions of the transactions they helped in verifying. They als Continue reading >>

It Is No Longer Worth It To Build An Ethereum Mining Rig

It Is No Longer Worth It To Build An Ethereum Mining Rig

It Is No Longer Worth It To Build An Ethereum Mining Rig Building an Ethereum mining rig hasnt been worth it for months, and soon they will be completely obsolete. Goodnight, sweet prince. Image: Daniel Oberhaus/Motherboard Back in May I wrote a guide explaining how to build an Ethereum mining rig , a special type of computer that forms the backbone of the Ethereum network and earns ether, the digital currency native to the network, for its owner. Shortly thereafter, Motherboard also made a video documenting this process . Since then, Ive received countless emails from readers inquiring about my mining rig. Ive received three such emails this week. The most common question voiced by these readers is whether or not it is still worth it to build a mining rig. The answer to this question is no. Building an Ethereum mining rig hasnt been worth it for months and a few months from now, mining ether will be completely obsolete. Read More: An Idiot's Guide to Building an Ethereum Mining Rig Arguably, building an Ethereum mining rig wasnt even worth it when I built my machine in May, and many readers let me know this when the article and video first came out. This is somewhat true, but there is a necessary caveat here. Mining ether also wasnt worth it for about the first year and a half of the cryptocurrencys existence. The price of ether hovered around $10 from 2015 until early 2017, when it saw a spike to $25. This was important because it meant the value of the ether being mined was higher than the cost of the electricity that was needed to mine it. In other words, until that point small scale mines were operating at a loss in the belief that the tokens they were mining would someday be worth a lot more money. In hindsight, these early miners were rightthe price of ether has Continue reading >>

Last updated on August 15th, 2017 at 11:06 pm Getting Started with Ethereum Mining the video guide The good news is that getting started with Ethereum Mining is now easier than ever. You do not need to download the full Ethereum blockchain, which is now over 20+ GBs and still growing! You also do not need to manage clunky command line miners with manual instructions. For purposes of this guide, we are going to do a detailed walk-through of setting up and using the very popular Claymore Miner. Get the current version here from Claymores original Bitcointalk thread and then follow along with the steps in this video. The whole process of getting a wallet setup, downloading your miner, configuring things in Windows and setting up your batch file to run should take less than 10 minutes: If youre new to mining Ethereum , this guide covers all the important facts in a simple, low-jargon way. Lets start with some short answers to common questions about Ethereum mining: Q: Whyshould Imine Ethereum tokens (aka ether or ETH)? doesnt mining Ether take up a lot of electricity? A: If done properly, more money is earned by selling mined ETH than is spent on electricity. In other words, its profitable! You can check out the profitability with our Ethereum mining calculator . Q: Can I mine with my CPU (Personal computersprocessor) instead ofan expensive graphics card (GPU)? A: GPUs are so much faster that CPU-mining is no longer profitable or worthwhile. Even entry-level GPUs are about 200 times faster than CPUs for mining purposes. Q: Whats the best GPU to use for getting the most ETH for the least electricity? A: AMD cards tend to edge out similarly-priced NVidia cards in terms of efficiency. We cover the best cards to get under the heading GPU Hardware further down in this post. Q: Continue reading >>

Ethereum: What Is Ethereum Mining? - The Economic Times

Ethereum: What Is Ethereum Mining? - The Economic Times

The maximum number of bitcoins are capped at 21 million while the total ether supply has no such cap Ethereum mining is fundamentally similar to bitcoin mining. Both use proof of work (PoW). PoW is a competitive activity that miners undertake to write transactions to a new block that will be added to the blockchain . A miner successfully mines a new block while competing with fellow miners by running a hashing script. Karan Bharadwaj, CTO of XinFin said, The specific scripts used in mining for bitcoin and ethereum are SHA-256(based script) and Ethash. Each block mined on ethereum also gives a payout of 5 ether to the miner. The bitcoin payout per block mined is 12.5 BTC that is set to halve to 6.25 in 2020. The maximum number of bitcoins are capped at 21 million while the total ether supply has no such cap. The developers behind the ethereum blockchain are working on shifting the mining algorithm from Proof of Work to Proof of Stake (PoS). PoS allows for the creation of new blocks with the expensive process of PoW mining. In PoS, each node participates in the consensus mechanism in a proportional manner to the stake (of the Ethereum blockchain) held by it, said Bharadwaj. With this shift to PoS, the block reward goes away and the miners are paid only in the form of transaction fees. This shift to PoS is going to remove the wasteful energy intensive process of mining while introducing additional security benefits to an already robust protocol. However, it is important to note that this is a very challenging implementation and not without complications. Rachit Chawla, CEO, Finway Capital said, Somewhat similar to bitcoin, Ethereum is also a popular cryptocurrency and ethereum mining is the process of mining ether; platform-specific cryptographic token, or simply, a uniqu Continue reading >>

Ethereum Mining Is Profitable, But Not For Long

Ethereum mining is profitable, but not for long Venture Capital | Investment Analysis | Deal sourcing + Execution. Previously founded and exited a profitable tech company in India You can also reach me at @shekhartee You can create a community post just like Shekhar here . This is a constant question, especially now that the price of Ethereum is rising. This year, Ethereum has seen an almost 20x jump in price. This increase has led people, who hadnt considered cryptocurrency, to sit down and become suddenly extremely interested. When this happens, I believe that most of the biggest profits have already been made. People have been mining the coin for months or years, and they have probably seen some tremendous gains, especially if they have a decent-sized operation. OK, lets get back to the question: Is it worth it to start mining? If you are just hearing about Ethereum and interested in maybe jumping onboard, this can be a very difficult question and the answer depends on a lot of factors. Well, hopefully, this article will help you get an idea of whether it is good to mine Ethereum. In elementary terms, Ethereum is an open software platform based on the blockchain technology that enables developers to build and deploy decentralized applications. I remember a friend once came up to me and asked, Is bitcoin and Ethereumsimilar? Well, sort of, but not really. Like bitcoin, Ethereum is a distributed public blockchain network. There are, of course, some significant technical differences, but the most important is that they differ substantially in purpose and capability. Bitcoin offers one application a peer-to-peer electronic cash system that enables bitcoin payments. The Ethereum blockchain can support many different types of decentralized applications. Wait, if it is a n Continue reading >>

How To Mine Ethereum In 5min

Surprisingly, all you need is an AWS EC2 instance to start mining Ethereum. Im sure youve already heard of the cryptocurrency craze way before reading this post. Cryptocurrencies are slowly and quietly revolutionizing the way financial systems and transactions work (and should work in my opinion). With Bitcoin hitting its $6K mark not awhile ago, a current total of $158B in market cap and hundreds of ICOs (Initial Coin Offering) conducted since August, its sure to say theres a bubble in the cryptocurrency space. Whats more, is that it doesnt seem this bubble is going anywhere, anytime soon. As you can see in the graph below, the total market cap of cryptocurrencies has grown from under $50B to over $150 in under a year! So what would be the best way to enter this space and enjoy the growth? Im not a cryptocurrency expert, however, from my research Ive found that the answer is pretty clear across all opinions: If youre looking for quick earnings, just invest incoins. However, due to this ever-growing crypto market, mining in the short term could lead to significant earnings in the long term. Personally, Im very interested in Ethereum , and have found an effortless way to start mining it quickly on AWS! This post will walk you through the process. But before we start, lets go over some basics. If youre already familiar with them, just scroll down. Ethereum is an open software platform based on the blockchain technology that enables developers to build and deploy decentralized applications. The advantage of Ethereum over Bitcoin, is that it can support many different types of decentralized applications. Ethereum has the second largest market cap after Bitcoin, and has gained massive growth in the last year with over 230% as you can see below: However, increasing growth in Continue reading >>

How Does Ethereum Mining Work?

How Does Ethereum Mining Work?

Largely the same way Bitcoin mining works today. When a new block is created, every mining node works to solve the next block. This is accomplished by hashing the previous block header and adding a random bit of data until the hash result (which can be interpreted as a number) is less than a target defined by the network. The process of hashing is such that the results are random and impossible to predict, so the only way to solve this problem is through brute force. Once this hash is below the value of the target, the block is sent out to the network, with all the transactions that have been collected, including a transaction to pay the miner the block reward and transaction fees. Then the process starts again. This process is how Ethereum currently works, but soon, the network will be moving to Proof of Stake, which does not have block rewards. You can read more about that here . Ethereum is mined largely in the same way mining of Bitcoins is done. During mining process, when a new block is created, every mining node works independently to solve the next block in the same way. This process of block to block management system is known as Blockchain Management Technology. One can easily mine ethereum with Hashgains using three simple mining steps. These include: Select your best power plan and make the payment accordingly. Collect your newly mined coins through wallet. In addition to Mining Bitcoins , you can mine multiple cryptocurrencies and use their power performance easily. This also increases the hashing power of mining Bitcoins and various other cryptocurrencies in an easy and effective way. This is accomplished by hashing the previous block header and adding a random bit of data until the hash result is less than a target defined by the network is achieved. Eth Continue reading >>

The word mining originates in the context of the gold analogy for crypto currencies. Gold or precious metals are scarce, so are digital tokens, and the only way to increase the total volume is through mining it. This is appropriate to the extent that in Ethereum too, the only mode of issuance post launch is via the mining. Unlike these examples however, mining is also the way to secure the network by creating, verifying, publishing and propagating blocks in the blockchain. Mining Ether = Securing the network = verify computation Ethereum Frontier like all blockchain technologies uses an incentive-driven model of security. Consensus is based on choosing the block with the highest total difficulty.Miners produce blocks which the others check for validity. Among other well-formedness criteria, a block is only valid if it contains proof of work (PoW) of a given difficulty.Note that in Ethereum 1.1, this is likely going to be replaced by a proof of stake model. The proof of work algorithm used is called Ethash (a modified version of Dagger-Hashimoto ) involves finding a nonce input to the algorithm so that the result is below a certain threshold depending on the difficulty. The point in PoW algorithms is that there is no better strategy to find such a nonce than enumerating the possibilities while verification of a solution is trivial and cheap. If outputs have a uniform distribution, then we can guarantee that on average the time needed to find a nonce depends on the difficulty threshold, making it possible to control the time of finding a new block just by manipulating difficulty. The difficulty dynamically adjusts so that on average one block is produced by the entire network every 12 seconds (ie., 12 s block time). This heartbeat basically punctuates the synchronisation Continue reading >>

How Do You Mine Ethereum?

How Do You Mine Ethereum?

By Nathan Reiff | February 9, 2018 3:18 PM EST Ethereum, like most cryptocurrencies, relies on the work of miners. While it's easy to assume that miners work to generate ether tokens (ETH) so that these tokens do not need to be created by a central issuer, there is more to the process of mining than this. ETH is generated through the mining process at a fixed rate of 5 ETH per block. Mining is also essential for a variety of other reasons: it helps to provide a log of the total pool of ETH which is available through the ethereum blockchain, thereby preventing fraudulent activity. It can also be a profitable venture for an individual. Before one can begin the process of mining ETH, though, it's essential to know a bit about how ethereum mining works. (See also: What Is Ether? Is It the Same as Ethereum? ) The process of mining for ethereum is very similar to that of bitcoin mining. Miners utilize powerful computers to make educated guesses about complex mathematical problems. This system is known as " proof of work ," because it requires that miners go through the puzzle-solving process in order to receive their ETH reward. Mining is accomplished by running unique metadata like timestamp and software versions for a block of transactions through a hash function repeatedly. Each repetition alters the " nonce value," which has an impact on the resulting hash value (a scrambled string of letters and numbers with a fixed length and a random appearance). If the hash value matches up with the current target for the block, the miner is rewarded with ETH, and the block is transmitted across the network so that each node in the network can validate the process and update the blockchain ledger. Other miners who had previously worked on solving the puzzle will move on to the next b Continue reading >>

How Ethereum Mining Works

How Ethereum Mining Works

Today, miners play an important role in making sure ethereum works. This role isn't immediately obvious, though. Many new users think that the sole purpose of mining is to generate ethers in a way that doesn't require a central issuer (seeour guide" What is Ether? "). This is true. Ethereum's tokens are created through the process of mining at a rate of 5 ether per mined block. But mining also has another at least asimportant role. Usually, banks are in charge of keeping accurate records of transactions. They ensure that money isn't created out of thin air, and that users don't cheat and spend their money more than once. Blockchains, though, introduce an entirely new way of record-keeping, one where the entire network, rather than an intermediary, verifies transactions and adds them to the public ledger. Although a 'trustless' or 'trust-minimizing' monetary system is the goal, someone still needs to securethe financial records, ensuring that no one cheats. Mining is one innovation that makes decentralized record-keeping possible. Miners come to consensus about the transaction history while preventing fraud (notably the double spending of ethers) an interesting problem that hadnt been solved in decentralized currencies before proof-of-work blockchains. Although ethereum is looking into other methods of coming to consensus about the validity of transactions, mining currently holds the platform together. Today, ethereum's mining process is almost the same as bitcoins . For each block of transactions, miners use computers to repeatedly and very quickly guess answers to a puzzle until one of them wins. More specifically, the miners will run the blocks unique header metadata (including timestamp and software version) through a hash function (which will return a fixed-length, Continue reading >>

What Are Ethereum Miners Really Solving?

What Are Ethereum Miners Really Solving?

As with mining, what are the ethereum miners really solving? I read they are solving hashes, but what does that really mean. Can we see what they are solving? Can someone give an example of what a ethereum mining machine sees to solve?Thx. Are you interested in understanding how Proof-of-Work/Proof-of-Stake as consensus mechanism works? Borinho May 8 at 7:09 As I understood Deem as me just wants to see that initial equation that programs is solving. and you send him to the common curses of the crypto currency and block chains. where we can find that underground equation??? Aug 21 at 19:47 So if you and I make a transaction using Bitcoin, Ether or basically any other Blockchain Technology the transaction is verified by solving a rather difficult math problem. What the miners are actually doing is verifying these transactions. They are doing the problem making sure its not a fraudulent transaction. MiningSo why should they do this? Why should they use their CPU's, GPU's & electricity to solve this very complex problem? Because the "winner" or the person who solves the answer first is rewarded or paid in the form of crypto currency. You should watch the Khan Academy Playlist of Videos on Bitcoin ... it will help.

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 >>

Proof Of Work Vs Proof Of Stake: Basic Mining Guide

Proof Of Work Vs Proof Of Stake: Basic Mining Guide

Proof of Work vs Proof of Stake: Basic Mining Guide Angel Investors, Startups & Blockchain developers... Recently you might have heard about the idea to move from an Ethereum consensus based on the Proof of Work (PoW) system to one based on the so-called Proof of Stake. In this article, I will explain to you the main differences between Proof of Work vs Proof of Stake and I will provide you a definition of mining, or the process new digital currencies are released through the network. Also, what will change regarding mining techniques if the Ethereum community decides to do the transition from work to stake? This article wants to be a basic guide to understanding the problem above. First of all, lets start with basic definitions. Proof of work is a protocol that has the main goal of deterring cyber-attacks such as a distributed denial-of-service attack (DDoS) which has the purpose of exhausting the resources of a computer system by sending multiple fake requests. The Proof of work concept existed even before bitcoin , but Satoshi Nakamoto applied this technique to his/her we still dont know who Nakamoto really is digital currency revolutionizing the way traditional transactions are set. In fact, PoW idea was originally published by Cynthia Dwork and Moni Naor back in 1993, but the term proof of work was coined by Markus Jakobsson and Ari Juels in a document published in 1999. But, returning to date, Proof of work is maybe the biggest idea behind the Nakamotos Bitcoin white paper published back in 2008 because it allows trustless and distributed consensus. Whats trustless and distributed consensus? A trustless and distributed consensus system means that if you want to send and/or receive money from someone you dont need to trust in third-party services. When you use tra Continue reading >>
