Most Read Under siege Makhura bemoans the spectre of factionalism in Gauteng. About 8, jobs on the line at Heineken. The figures provide little comfort for businesses not directly tapped into the resources sector. Retailer Paul FitzRoy says only businesses directly tied to the booming sector can really afford the ever-increasing rents. All we see is the cost of living skyrocketing. Bankwest economist Alan Langford says it could be worse. Interest rates would be running about 2 percentage points higher than they would be on the east coast.

Luckily for local exporters, the industry-destroying currency rate never eventuated, even though 68 per cent of West Australians approved of a split from the rest of the nation in a referendum on the issue. Langford says interest rate concerns, which are in part caused by a pipeline of good projects, is a problem that other economies would like to have. The high wages on offer in the male-dominated resources sector flow through into a gender disparity, according to an analysis of ABS data.

West Australian men earn more than 25 per cent more than women —by far the biggest discrepancy between the genders among the states. Billionaire mining magnate Andrew Forrest believes the mining sector is the solution, not the problem. There is, however, a concern that the good news flowing out of the Pilbara, buoyed by large-scale liquified natural gas projects, weighs too much on Reserve Bank of Australia officials in Sydney fearing an inflation outbreak.

An interest rate rise suddenly looks less logical, the argument goes, when you speak with a nervous consumer or hesitant home buyers. There might be a presumption in the eastern states that West Australians can shrug off rate rises, buoyed by their mineral resources. The figures are not dissimilar to the rents paid at the top-end shopping strips of the eastern states. Rents and general living costs are so high in the epicentre of the boom that the Shire of East Pilbara has felt it necessary to regulate the use of sea shipping containers.

Nonetheless, businesses and residents in the area are known to use the storage facility as an office or sleeping quarters because of the prohibitive rents and high costs of construction. The price represents almost a three-fold increase over the last five years, making it almost essential to have a living allowance from a good employer in order to avoid the government housing queue. State Treasurer Christian Porter says there are limits to legislative measures that can keep all sectors of the economy advancing at the same speed.

Now imagine that I pose the 'guess what number I'm thinking of' question, but I'm not asking just three friends, and I'm not thinking of a number between 1 and Rather, I'm asking millions of would-be miners and I'm thinking of a digit hexadecimal number.

Now you see that it's going to be extremely hard to guess the right answer. Not only do bitcoin miners have to come up with the right hash, but they also have to be the first to do it. Because bitcoin mining is essentially guesswork, arriving at the right answer before another miner has almost everything to do with how fast your computer can produce hashes.

Just a decade ago, bitcoin mining could be performed competitively on normal desktop computers. Over time, however, miners realized that graphics cards commonly used for video games were more effective and they began to dominate the game. In , bitcoin miners started to use computers designed specifically for mining cryptocurrency as efficiently as possible, called Application-Specific Integrated Circuits ASIC. These can run from several hundred dollars to tens of thousands but their efficiency in mining Bitcoin is superior.

Today, bitcoin mining is so competitive that it can only be done profitably with the most up-to-date ASICs. Even with the newest unit at your disposal, one computer is rarely enough to compete with what miners call "mining pools. A mining pool is a group of miners who combine their computing power and split the mined bitcoin between participants. A disproportionately large number of blocks are mined by pools rather than by individual miners.

Mining pools and companies have represented large percentages of bitcoin's computing power. Consumers tend to trust printed currencies. In addition to a host of other responsibilities, the Federal Reserve regulates the production of new money, and the federal government prosecutes the use of counterfeit currency. Even digital payments using the U.

When you make an online purchase using your debit or credit card, for example, that transaction is processed by a payment processing company such as Mastercard or Visa. In addition to recording your transaction history, those companies verify that transactions are not fraudulent, which is one reason your debit or credit card may be suspended while traveling. Bitcoin, on the other hand, is not regulated by a central authority.

Nodes store information about prior transactions and help to verify their authenticity. Unlike those central authorities, however, bitcoin nodes are spread out across the world and record transaction data in a public list that can be accessed by anyone. Between 1 in 16 trillion odds, scaling difficulty levels, and the massive network of users verifying transactions, one block of transactions is verified roughly every 10 minutes.

The bitcoin network is currently processing just under four transactions per second as of August , with transactions being logged in the blockchain every 10 minutes. At that point, waiting times for transactions will begin and continue to get longer, unless a change is made to the bitcoin protocol.

There have been two major solutions proposed to address the scaling problem. Developers have suggested either 1 creating a secondary "off-chain" layer to Bitcoin that would allow for faster transactions that can be verified by the blockchain later, or 2 increasing the number of transactions that each block can store. With less data to verify per block, the Solution 1 would make transactions faster and cheaper for miners. Solution 2 would deal with scaling by allowing for more information to be processed every 10 minutes by increasing block size.

The program that miners voted to add to the bitcoin protocol is called a segregated witness , or SegWit. Less than a month later in August , a group of miners and developers initiated a hard fork , leaving the bitcoin network to create a new currency using the same codebase as bitcoin.

Although this group agreed with the need for a solution to scaling, they worried that adopting segregated witness technology would not fully address the scaling problem. Instead, they went with Solution 2. Bitcoin Block Half. Board of Governors of the Federal Reserve System. Coin Desk. Your Money. Personal Finance. Your Practice. Popular Courses. Part Of.

Key Takeaways Bitcoin mining is the process of creating new bitcoin by solving a computational puzzle. Bitcoin mining is necessary to maintain the ledger of transactions upon which bitcoin is based.

Miners have become very sophisticated over the last several years using complex machinery to speed up mining operations. Article Sources. The reason is that every bitcoin transaction has a transaction fee attached to it. These fees, while today representing a few hundred dollars per block, could potentially rise to many thousands of dollars per block, especially as the number of transactions on the blockchain grows and as the price of a bitcoin rises.

Ultimately, it will function like a closed economy , where transaction fees are assessed much like taxes. It's worth noting that it is projected to take more than years before the bitcoin network mines its very last token. In actuality, as the year approaches, miners will likely spend years receiving rewards that are actually just tiny portions of the final bitcoin to be mined.

The dramatic decrease in reward size may mean that the mining process will shift entirely well before the deadline. It's also important to keep in mind that the bitcoin network itself is likely to change significantly between now and then. Considering how much has happened to bitcoin in just a decade, new protocols, new methods of recording and processing transactions, and any number of other factors may impact the mining process.
