It takes 20 barrels of oil to mine one bitcoin according to some number crunching, with the network spil a entire consuming an omschrijving of 13,239,916 barrels of oil every single year.
That’s almost enough to power the entire United States for one day, while UK can get through for around two weeks on what bitcoin consumes te a year.
That includes everything, from airplanes, to cars, to trains, with bitcoin’s mining energy consumption being some 40 times greater than Visa.
However, this considerable use of physical resources, mainly concentrated ter China, does not necessarily increase capacity or bitcoin’s functionality.
The only service it provides is a greater requirement ter resources for an outward entity to 51% attack the bitcoin network.
Something which, at the current levels, might be practically unlikely te most circumstances considering the enormous amount of hardware and energy required.
But is Proof of Work, and the everzwijn growing consumption of physical resources for the foot purpose of securing the bitcoin network, the only way?
Ethereum, the 2nd largest digital currency, does not think so. Instead of using an algorithm that requires sophisticated calculations through specialized hardware, ethereum’s algorithm, called Proof of Stake, will simply require the depositing of eth.
Proof of Work is ter many way a code based method of ensuring identity. Instead of requiring official documentation, your hardware undertakes some “work.” Thus proving that it is one entity and that it’s a real rekentuig.
This way, by requiring work, the process can’t be faked. Unlike knots, which are fairly effortless to produce ter large numbers either on the cloud or by spoofing and faking them.
But another way of proving identity is by using something else which is uncommon. Ter the case of ethereum, rather than “work,” that uncommon thing is eth itself.
Once the Proof of Stake upgrade is implemented, which might be sometime te 2018, you then “deposit” eth to your laptop eth knot, and thus commence taking part ter the overeenstemming algorithm where 51% prevails.
Since the number of eth is limited and pretty expensive, gaining 51% of them would, even at current market prices, cost some $15 billion.
Hardly a worthy endeavor for the foot purpose of attacking the network. Thus, this alternative way would ensure security while at the same time keeping our oil and electric current for what is indeed needed, such spil keeping warm during winter, or flying to the beach during summer.
The upgrade is complicated, and very likely one of the fattest achievement te this space if it is sleekly implemented. Its complexity is derived from the complicated spel theory needed to ensure all “miners” stay te overeenstemming.
One way it does so is by the code itself penalizing those that misbehave by ter effect taking away their “deposit,” so leaving them penniless.
Albeit the algo is not yet finalized, it is probable that some 51% of them might need to misbehave. Which, considering the penalty facet, might not be much different than with Proof of Work. And, likewise, the why not just behave and get “dividends” te fresh coins, applies.
So all this energy consumption might be improvised. Especially if Proof of Stake is shown to slickly work ter activity. Then wij might have a green, clean, and perhaps even more decentralized network, spil knots are ultimately incentivized to directly take part te the overeenstemming process.
