6 Best Bitcoin Mining Hardware Asics Comparison In 2017

The best Bitcoin mining hardware has evolved dramatically since 2009 At first, miners used their central processing unit (CPU) to mine, but soon this wasn't fast enough and it bogged down the system resources of the host computer. Miners quickly moved on to using the graphical processing unit (GPU) in computer graphics cards because they were able to hash data 50 to 100 times faster and consumed much less power per unit of work. During the winter of 2011, a new industry sprang up with custom equipment that pushed the performance standards even higher. The first wave of these specialty bitcoin mining devices were easy to use Bitcoin miners were based on field-programmable gate array (FPGA) processors and attached to computers using a convenient USB connection. FPGA miners used much less power than CPU's or GPU's and made concentrated mining farms possible for the first time. Today's modern and best bitcoin mining hardware Application-specific integrated circuit (ASIC) miners have taken over completely. These ASIC machines mine at unprecedented speeds while consuming much less power than FPGA or GPU mining rigs. Several reputable companies have established themselves with excellent products. Currently, based on (1) price per hash and (2) electrical efficiency the best Bitcoin miner options are: For a comprehensive comparison of bitcoin mining hardware.

Is Your Computer Secretly Mining Bitcoin Alternatives? A Guide To Cryptojacking

Is Your Computer Secretly Mining Bitcoin Alternatives? A Guide To Cryptojacking

Is Your Computer Secretly Mining Bitcoin Alternatives? A Guide to Cryptojacking Some web sites and apps that dont charge you for their services have found a new way to make money from you: using your computer to generatevirtual currencies By Bill Buchanan , The Conversation US on December 28, 2017 The following essay is reprinted with permission from The Conversation , an online publication covering the latest research. Nothing comes for free, especially online. Websites and apps that dont charge you for their services are often collecting your data or bombarding you with advertising. Now some sites have found a new way to make money from you: using your computer to generate virtual currencies . Several video streaming sites and the popular file sharing network The Pirate Bay have allegedly been cryptojacking their users computers in this way, as has the free wifi provider in a Starbucks cafe in Argentina . Users may object to this, especially if it slows down their computers. But given how hard it is for most companies to make money from online advertising, it might be something we have to get used to unless we want to start paying more for things. Units of cryptocurrencies such as bitcoin arent created by a central bank like regular money but are generated or mined by computers solving complex equations. Cryptojacking involves using someones computer without their knowledge, perhaps for just seconds at a time, to mine a cryptocurrency. In the case of bitcoin, mining requires specialised hardware and consumes masses of energy. For example, each bitcoin transaction takes enough energy to boil around 36,000 kettles filled with water. In a year, the whole bitcoin mining network consumes more energy than Ireland . But bitcoin is not the only show in town and there are man Continue reading >>

5 Best Bitcoin Mining Hardware Asics 2017 / 2018 (comparison)

5 Best Bitcoin Mining Hardware Asics 2017 / 2018 (comparison)

Originally, Satoshi intended for Bitcoin to be mined on computer CPUs. However, Bitcoin miners discovered they could get more hashing power from graphic cards. Graphic cards were then surpassed by ASICs ( Application Specific Integrated Circuits ). Nowadays all serious Bitcoin mining is performed on dedicated Bitcoin mining hardware ASICs, usually in thermally-regulated data-centers with access to low-cost electricity. Think of a Bitcoin ASIC as specialized Bitcoin mining computers, Bitcoin mining machines, or bitcoin generators. There are also Bitcoin hardware wallets like the Ledger Nano S , which store bitcoins. There are some important factors to look at when determining which Bitcoin mining ASIC to buy: Hash rate How many hashes per second can the Bitcoin miner make? More hashes cost more, which is why efficiency is crucial Efficiency Youll want to buy the most efficient bitcoin mining hardware possible. Since miners use a large amount of electricity, you want to buy one that converts the most amount of electricity into bitcoins. Price How much does the bitcoin miner cost? Cheap mining hardware will mine less bitcoins, which is why efficiency and electricity usage are important. The fastest and more efficient mining hardware is going to cost more. Dont try to buy a miner based on only price or only hash rate. The best ASIC miner is the most efficient bitcoin miner. Aim for value.

Thieves Steal 600 Powerful Bitcoin-mining Computers In Huge Heist

Thieves Steal 600 Powerful Bitcoin-mining Computers In Huge Heist

Thieves steal 600 powerful bitcoin-mining computers in huge heist In Iceland, police are hoping a power surge will lead them to the criminals' stash. 600 powerful servers specifically designed to mine bitcoin. ( What is bitcoin? Here's everything you need to know .) Plus 600 graphics cards, 100 processors, 100 power supplies, 100 motherboards and 100 sets of computer memory. According to The Associated Press and Visir , those are the items a coordinated group of Icelandic thieves has stolen. And though 11 people have reportedly been arrested and at least two are still in custody, none of the stolen computers have yet been found by police. The thefts, which occured between late December and early January, were reportedly captured on surveillance cameras by Advania , the server company hit by two of the three thefts. (The graphics cards, processors and so on were allegedly stolen from a home.) Advania had been offering its customers access to bitcoin-mining rigs, and it sounds like those were the type that were stolen. The Associated Press reports that the stolen computers are worth nearly $2 million. "This is a grand theft on a scale unseen before," Police Commissioner Olafur Helgi Kjartansson said, according to the AP . "Everything points to this being a highly organized crime." The AP reports that police are tracking energy consumption across Iceland in case the thieves turn on their new computers and place a strain on the grid, since that could potentially lead them back to the stolen computers' location.

Illegal Bitcoin Mining Factory Sparks Massive Blaze Thanks To Overheating Computers Used To Create Cryptocurrency

Illegal Bitcoin mining factory sparks massive blaze thanks to overheating computers used to create cryptocurrency Fire destroyed eight flats and flooded 30 more at a residential block in eastern Russia AN inferno at a block of flats is believed to have been caused by overheating computers in an illegal bitcoin mining factory. The night-time blaze in eastern Russia destroyed eight apartments and flooded dozens more as firefighters tackled the flames. The fire broke out on the top floor of the apartment block in Artem, near Vladivostok Pictures after it was put out showed charred computer equipment found on the top floor- said to have been used for "mining" the virtual currency . Experts suspect a resident had illegally tapped into the blocks electricity supply, leading to a heavy power surge. Locals in Artem, near Vladivostok, said it was a miracle no one died. The Emergencies Ministry confirmed: "We have spotted something which looks like mining equipment. Eight flats were destroyed and around 30 damaged by flooding And aresident called Oleg said that mining rig equipment was found in the attic. He said: I would now ban miners totally... so many apartments are burned completely, and 30 are flooded. Many Russians are seeking to get rich quick though bitcoins after an explosion in their value. Mining - using software to verify blockchain transactions and create new units of the cryptocurrency - is legal. But the powerful computer equipment needed uses lots of electricity, and in a number of cases miners have broken into power supplies of residential blocks or warehouses. Firefighters warn this overheats electrical circuits with potentially deadly consequences. Fire crews found charred computer equipment in the block Resident Roman Vislobokov told The Siberian Times : Our Continue reading >>

Mining - Bitcoin Wiki

Mining - Bitcoin Wiki

Mining is the process of adding transaction records to Bitcoin's public ledger of past transactions (and a " mining rig " is a colloquial metaphor for a single computer system that performs the necessary computations for "mining").This ledger of past transactions is called the block chain as it is a chain of blocks .The block chain serves to confirm transactions to the rest of the network as having taken place.Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere. Mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function. The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus.Mining is also the mechanism used to introduce Bitcoins into the system:Miners are paid any transaction fees as well as a "subsidy" of newly created coins.This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system. Bitcoin mining is so called because it resembles the mining of other commodities:it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground. Mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. This problem can be simplified for explanation purposes: The hash of a bl Continue reading >>

How To Set Up A Bitcoin Miner - Coindesk

How To Set Up A Bitcoin Miner - Coindesk

There are three main categories of bitcoin mining hardware, each more expensive and more powerful than the last. This guide to setting up a bitcoin miner explains each of them, and talks about how to make them work. By this stage, you will understand how bitcoin works , and what mining means. But we need to get from theory to practice. How can you set up a bitcoin mining hardware and start generating some digital cash? The first thing you're going to need to do is decide on your hardware, and there are two main things to think about when choosing it: This is the number of calculations that your hardware can perform every second as it tries to crack the mathematical problem we described in our mining section. Hash rates are measured in megahashes, gigahashes, and terahashes per second (MH/sec, GH/sec, and TH/sec. The higher your hash rate (compared to the current average hash rate), the more likely you are to solve a transaction block. The bitcoin wikis mining hardware comparison page is a good place to go for rough information on hash rates for different hardware. All this computing power chews up electricity, and that costs money. It's worth looking at your hardware's energy consumption in watts, when making your choice. You want to make sure that you don't end up spending all of your money on electricity to mine coins that won't be worth what you paid. Use these two factors to work out how many hashes youre getting for every watt of electricity that you use. To do this, divide the hash count by the number of watts. For example, if you have a 500 GH/sec device, and its taking 400 watts of power, then youre getting 1.25 GH/sec per watt. You can check your power bill or use an electricity price calculator online to find out how much that means in hard cash. However, the Continue reading >>

How Bitcoin Mining Works - Coindesk

How Bitcoin Mining Works - Coindesk

In traditional fiat money systems, governments simply print more money when they need to. But in bitcoin, money isn’t printed at all – it is discovered. Computers around the world ‘mine’ for coins by competing with each other. People are sending bitcoins to each other over the bitcoin network all the time, but unless someone keeps a record of all these transactions, no-one would be able to keep track of who had paid what. The bitcoin network deals with this by collecting all of the transactions made during a set period into a list, called a block. It’s the miners’ job to confirm those transactions, and write them into a general ledger. This general ledger is a long list of blocks, known as the 'blockchain'. It can be used to explore any transaction made between any bitcoin addresses, at any point on the network. Whenever a new block of transactions is created, it is added to the blockchain, creating an increasingly lengthy list of all the transactions that ever took place on the bitcoin network. A constantly updated copy of the block is given to everyone who participates, so that they know what is going on. But a general ledger has to be trusted, and all of this is held digitally. How can we be sure that the blockchain stays intact, and is never tampered with? This is where the miners come in. When a block of transactions is created, miners put it through a process. They take the information in the block, and apply a mathematical formula to it, turning it into something else. That something else is a far shorter, seemingly random sequence of letters and numbers known as a hash. This hash is stored along with the block, at the end of the blockchain at that point in time. Hashes have some interesting properties. It’s easy to produce a hash from a collection Continue reading >>

Bitcoin Mining - What Is It And Is It Profitable In 2018? A Beginner's Guide

Last updated on November 24th, 2017 at 08:12 am Before we start, if youre new to Bitcoin mining and dont know what it is watch this short and simple explanation: The short answer would be It depends on how much youre willing to spend. Each person asking himself this will get a slightly different answer since Bitcoin Mining profitability depends on many different factors. In order to find out Bitcoin mining profitability for different factors mining profitability calculators were invented. These calculators take into account the different parameters such as electricity cost, the cost of your hardware and other variables and give you an estimate of your projected profit. Before I give you a short example of how this is calculated lets make sure you are familiar with the different variables: Bitcoin Mining terms you should get to know Hash Rate A Hash is the mathematical problem the miners computer needs to solve. The Hash Rate is the rate at which these problems are being solved. The more miners that join the Bitcoin network, the higher the network Hash Rate is. The Hash Rate can also refer to your miners performance. Today Bitcoin miners (those super powerful computers talked about in the video) come with different Hash Rates. Miners performance is measured in MH/s (Mega hashper second), GH/s (Giga hash per second), TH/s (Terra hashper second) and even PH/s (Peta hashper second). Bitcoins per Block Each time a mathematical problem is solved, a constant amount of Bitcoins are created.The number ofBitcoinsgenerated per block starts at 50 and is halved every 210,000 blocks (about four years). The current number of Bitcoins awarded per block is 12.5. The last block halving occurred on July 2016 and the next one will be in 2020.
