ABC employee caught mining for Bitcoins on company servers

Updated March 09, You can buy bitcoins with fiat currencies — legal tender backed by the issuing government, like Australian dollars — through online exchanges, or you can create brand new bitcoins in a process known as mining.

The main feature of cryptocurrencies is that they operate on a decentralised peer-to-peer network, with no central authority or government backing. The underlying technology that makes cryptocurrencies such as bitcoin possible is what is known as the "blockchain". When a transaction is made it is added to the end of the blockchain and confirmed using a series of complex computations by the computers of other users who are on that currency's network.

The most recent transactions made on the network are bundled up into a transaction "block", which is finalised roughly every 10 minutes.

Once a computer solves the block's complex equations and finds a valid hash key it is added to the blockchain, verifying bitcoin transactions between users, abc bitcoin mining at the same time rewarding the miner with new bitcoins.

It can take a while for miners to reap rewards, as only the first user to solve the block by finding one of a number of valid hash abc bitcoin mining is rewarded with bitcoins. During the early days of bitcoin ina common household computer would have been powerful enough to mine for dozens of new coins using its CPU or GPU.

The currency automatically regulates the difficulty of the mathematical problem adding complexity to the hash value computers need to find as well as the number of bitcoins received as a reward. If a lot of people are connected to the network to mine for bitcoins, the difficulty of abc bitcoin mining a block increases. This is known as the hash rate. The number of bitcoins rewarded also adjusts, with an end result that means every four years only half the abc bitcoin mining of coins created in the previous four years can be made.

Recently, the invention of specialised computers used solely for mining has dramatically increased the difficulty of obtaining bitcoin. Bitcoins can be mined solo or as part of a pool, but even then the bitcoin or fraction of the coin you receive will likely not be enough to cover the electricity cost.

Bitcoin mining was extremely easy when the network first began, but it is now out of the realm of common home computers. Due abc bitcoin mining the way Bitcoin was coded, there is a limit of just under 21 million bitcoins that can be created. However, a single bitcoin can be subdivided as far down as abc bitcoin mining eighth decimal place 0. Want to know more about bitcoin? Read our explainer to see exactly how the cryptocurrency works.

Bitcoin "miners" who use rows of computers whirring at the same time to produce virtual currencies began taking root along New York's northern border a couple of years ago to tap into some of the nation's cheapest hydroelectric power, offering an air of Silicon Valley sophistication to this often-snowy region. But as the once-high-flying bitcoin market has waned, so too has the enthusiasm for bitcoin miners. Mining operations with stacks of servers suck up so much electricity that they are in some cases causing power rates to spike for ordinary customers.

And some officials question whether it's all worth it for the relatively few jobs created. In Plattsburgh, where two cryptocurrency operations have been blamed for spiking electricity rates, the prospect of more cryptocurrency miners plugging in spooked officials enough in March to enact an month moratorium on new operations. The small border village of Rouses Point also is holding off on approving new server farms and Lake Placid is considering a moratorium.

For local officials, the power struggle has been a crash course in the esoteric bitcoin mining business in which miners earn bitcoins by making complex calculations that verify transactions on the digital currency's public ledger.

Since it often uses hundreds of computers that throw off tremendous heat and burn a lot of power, it has tended to gravitate towards cooler places with cheap electricity, such as geothermal-rich Iceland or along the Columbia River region of Washington state. The stretch of New York near the Canadian border similarly fits the bill.

Cheap hydropower from a dam spanning the St. Lawrence River is doled out by a state authority to local businesses that promise to create jobs. Additionally, some municipalities such as Massena and Plattsburgh receive cheap electricity from a separate hydropower project near Niagara Falls.

In Plattsburgh, electricity is so cheap most residents use it instead of oil or wood to heat their homes. The couple of commercial cryptocurrency mines here can get an industrial rate of about 3 cents per kilowatt hour — less than half the national average. But Plattsburgh Mayor Colin Read said its largest operator, Coinmint, which has two plants employing 20 or fewer people, can consume about 10 percent of Plattsburgh's megawatt cheap electricity quota. State regulators have since given municipal utilities the ability to charge higher rates to cryptocurrency miners.

At least one bitcoin miner in Plattsburgh says he's working with the city on solutions to the power worries. Ryan Brienza, founder and CEO of the hosting company Zafra, said those could include mining on behalf of the city for an hour a day or harnessing the heat from mining computers to warm up large spaces.

While the direct number of jobs associated with mines can be small, Brienza said they can bring revenue, investments and talent to the city while employing local contractors.

Coinmint's plans for a new plant in Massena, for example, come with a promise of jobs. That's welcome in an area that in the past decade has suffered though the loss of aluminum-making jobs and the closure of a General Motors powertrain plant. What we need up here," said Steve O'Shaughnessy, Massena town supervisor. Coinmint had asked for a cheap power allocation from the New York Power Authority for Massena for part of its energy needs, but that request was deferred.

The power authority has separately enacted its own moratorium on allocating hydropower to cryptocurrency operations — mirroring municipalities that have effectively pushed the "pause" button on a rush of miners coming in.

Coinmint representatives said this month they hope to begin the Massena operation in the second part of this year. The company stressed that mines can be a good fit for this job-hungry area.
