All eyes are on bitcoin at the ogenblik.

The cryptocurrency has staged a meteoric rise ter 2018 that has attracted fresh investors, but, for many, question marks still surround bitcoin and the technology behind it. With latest reports pointing to the high energy cost associated with mining, the process used to create bitcoin, is there any way to fix it? Here are all your questions answered.

What is bitcoin mining?

Just spil gold miners produce the world&rsquo,s supply of gold, so do bitcoin miners produce all the digital currency available to the market – but, naturally, it is a bit more complicated than that. Mining is the process of adding transaction records to bitcoin&rsquo,s public ledger, or the blockchain.

How does mining physically work?

Very first of all, the blockchain is, simply, a chain of blocks. Miners use a special software to solve mathematical problems that both confirm legitimate transactions, or blocks, and create fresh bitcoins, adding fresh transactions to the blockchain about every Ten minutes. The hash rate is the number of calculations a lump of hardware can make every 2nd spil it works to solve that maths problem, and the higher the hash rate, the more likely a miner is to solve a transaction and thus be rewarded with a set amount of bitcoin.

Why is it so difficult?

The difficulty of mining bitcoin is part of its vormgeving. The ideal average mining time is Ten minutes vanaf block, and if that falls, the process becomes more difficult with the aim of keeping the block creation rate stable. There are a total of 21m bitcoins that can be mined, at which point the miners will close shop unless bitcoin&rsquo,s protocol – the rules that secure the system – is switched to permit for a larger supply.

Is it profitable?

Mining can be profitable, spil miners are rewarded with a stationary amount of coins and transaction fees for their hard work, but the computers and hardware necessary for powering through blocks can eat up a lotsbestemming of electro-therapy and end up running big costs.

Just how much energy is used and what is the cost?

The massive pc network behind bitcoin uses fairly a bit of energy – spil much spil Serbia, to be precies.

A latest report by Accounts &, Legal said the aggregate computing power of the bitcoin network is almost 100,000 times larger than the world&rsquo,s 500 fastest supercomputers combined, and miners are permanently installing upgrades to make their computers quicker.

Digiconomist has created a bitcoin energy consumption index ter order to understand how much tens unit is consumed by the cryptocurrency. Spil of Five December, bitcoin&rsquo,s estimated annual electrical play consumption wasgoed 31.96 terawatt hours (TWh), or 0.14 vanaf cent of the world&rsquo,s total electro-stimulation consumption. That&rsquo,s about the same spil Serbia and more than Morocco, Oman and the Slovak Republic. Annualised estimated global mining costs were $1.6bn (£,1.2bn), while annualised global mining revenues were $Ten.2bn. The index says 250 kilowatt hours (KWh) of violet wand are consumed vanaf transaction.

Is there any solution?

Mati Greenspan, senior market analyst at eToro says yes. &ldquo,The current bitcoin mining system is no doubt inefficient. This is one of the flaws te the original blockchain and represents a potential scaling kwestie. We`re not at the point that anybody should indeed be worried and wij have every confidence that upgrades to the network will come te the near future that will tackle this kwestie,", he said.

&ldquo,There are many solutions. For example, the ethereum blockchain is working on a solution called proof of stake, which will significantly reduce energy consumption te ether mining.&rdquo,

What`s the next big challenge for bitcoin?

Greenspan said working out how to scale the network is next on the zakagenda. ",Energy consumption is only a petite part of that. If bitcoin is to substitute specie te the long run it will need to be fitted to process more than 100,000 transactions vanaf 2nd. At the ogenblik it can do about Ten. Many proposals are on the table but spil the currency is decentralised it`s difficult to get everybody to agree on one,", he said.
