In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. issues around environmental sustainability, and that bitcoin was only energy-intensive through the mining process, not transactions. Nonoutsourceable scratch-off puzzles to discourage bitcoin mining coalitions. cern.makingmemorie.com Bitcoin Wiki. HOW RISKY IS CRYPTOCURRENCY TRADING

As the rate of block generation increases, the difficulty rises to compensate, which has a balancing of effect due to reducing the rate of block-creation. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by the other participants in the network. When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network.

Currently this bounty is 6. See Controlled Currency Supply. Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.

Users have used various types of hardware over time to mine blocks. Hardware specifications and performance statistics are detailed on the Mining Hardware Comparison page. Early Bitcoin client versions allowed users to use their CPUs to mine. The option was therefore removed from the core Bitcoin client's user interface. A variety of popular mining rigs have been documented. FPGAs typically consume very small amounts of power with relatively high hash ratings, making them more viable and efficient than GPU mining.

An application-specific integrated circuit, or ASIC , is a microchip designed and manufactured for a very specific purpose. ASICs designed for Bitcoin mining were first released in For the amount of power they consume, they are vastly faster than all previous technologies and already have made GPU mining financially.

Mining contractors provide mining services with performance specified by contract, often referred to as a "Mining Contract. As more and more miners competed for the limited supply of blocks, individuals found that they were working for months without finding a block and receiving any reward for their mining efforts. This made mining something of a gamble.

To address the variance in their income miners started organizing themselves into pools so that they could share rewards more evenly. See Pooled mining and Comparison of mining pools. Bitcoin's public ledger the "block chain" was started on January 3rd, at UTC presumably by Satoshi Nakamoto. The first block is known as the genesis block. The first transaction recorded in the first block was a single transaction paying the reward of 50 new bitcoins to its creator. Staking is a concept in the Delegated proof of stake coins, closely resembling pooled mining of proof of work coins.

The network periodically selects a pre-defined number of top staking pools usually between 20 and , based on their staking balances, and allows them to validate transactions in order to get a reward. The rewards are then shared with the delegators, according to their stakes with the pool.

A lot of altcoins are using staking. Staking is often marketed as a much more efficient alternative. Unfortunately staking has the potential to not be much different than politics. A good example is that it's easy for a big actor to take over the network by simply buying enough coins.

This actually happened in when TRON's Justin Sun took over the Steem "forum" network and then did some things that made some people unhappy. Abcd9 talk , 12 January UTC [ reply ]. This research study would not have been possible without the generous support and participation from industry actors: we would like to express our gratitude to the following cryptoasset entities for contributing to this research study by completing our surveys.

Some survey respondents prefer not to publicly disclose their participation. Nowhere in their publications is there a statement about governance or any apparent good governance policy, such as whether the support from the large number of crypto businesses includes financial support or more direct participation.

There is no claim that they are independent of influence or loyalties to the listed supporting crypto businesses and bitcoin related agencies, or indeed the secret support of companies which as not been disclosed but is stated by the CCAF to exist. Robert Wardrop is the director of the CCAF and has a "portfolio of senior advisory and board-level positions" which is not publicly declared.

Sponsored content is generally unacceptable as a source, because it is paid for by advertisers and bypasses the publication's editorial process. Reliable publications clearly indicate sponsored articles in the byline or with a disclaimer at the top of the article. For large-scale miners, we use a PUE of 1. For medium-scale miners, we use a PUE of 1.

For small-scale miners, we assume a PUE of 1. This proposal aims to stop accepting cryptocurrencies because they use "enormous amount of energy". However, we should care about the carbon footprint, and not the mere energy consumption. Bitcoin is therefore a green energy stimulus, aligned with the Wikimedia Foundation's commitment to environmental sustainability. It should be promoted as such. Panic as Kosovo pulls the plug on its energy-guzzling bitcoin miners Interestingly enough, in another part of Europe, Swedish regulators are complaining that Bitcoin mining uses too much renewable energy.

Even when assuming that Bitcoin mining was exclusively powered by coal - a very unrealistic scenario given that a non-trivial number of facilities run exclusively on renewables - total carbon dioxide emissions would not exceed 58 million tons of CO2, which would roughly correspond to 0. This research study would not have been possible without the generous support and participation from industry actors.

In particular, it would account for approximately 5. Environmental disaster : The energy usage of bitcoin alone is staggering, consuming as much electricity as some countries, and this is likely to keep increasing as the technology behind it does not and cannot scale in any reasonable way. While so many of us are trying our best to reduce our carbon footprints, it feels counterproductive to indulge in technology that undoes that hard work.

Given the proven cryptocurrency forum canvassing actively going on, and its speed, could we agree that this RFC has all single purpose account edits reverted. Though it is often normal to just mark accounts which are clearly part of a canvassing campaign, the manipulation of this RFC by off-wiki canvassing has been fast and significant, with the risk that both vote gaming and manipulation of discussion to introduce bias and fake "bitcoin" news, will disrupt and confuse the outcome.

Frankly the page already looks a mess from this manipulation. A radical thought experiment can provide an alternative perspective on this question. In this worst-case scenario, the Bitcoin network would be responsible for about Mt million metric tons of carbon dioxide emissions1, accounting for roughly 0.

Bitcoin uses 80 per cent more energy than it did at the beginning of The Cambridge Centre now estimates the annualized electricity consumption at the beginning of was Much despite not all of the rationale for this proposal and the discussion is about environmental burden of cryptocurencies. Much is focused on quantifying the environmental impact specifically of Bitcoin BTC. But, as colleagues above have already mentioned, Bitcoin is not the only one available cryptocurrency.

And many more cryptos are by principle significantly less damaging. A quick web search shows e. Also, an extensive article from leafscore. Some of these are declared to be carbon neutral, some wants to become carbon neutral, some uses its fees for planting trees.

Some are even very competitive in energy usage to the traditional banking system even if not calculating oil backed petrodolars So, if environmental sustainability is really so important to us as we declare and I hope so , we have some decent options for reforming our crypto acceptance, rather than destroying it. Another section relying on "sources" that turn out to be opinion pieces. No published academic research here, just claims and counter-claims which even the cited but paywall protected "Times" money mentor article states as dubious and nothing as firm as the United Nations statement that directly compared a Bitcoin transaction energy cost to a Visa transaction energy cost as being a million times more.

These discussions now read like a Bitcoin forum, full of non-scientific claims sourced to incomprehensible hand-waiving cryptocurrency advertorial self-publications. These are identical to the distract, confuse, counter-claim tactics of climate denial "science" a decade ago and mostly irrelevant to what are allowed as current donation methods to the Wikimedia Foundation which this vote is supposed to be about. Anonymous donations work without relying on cryptocurrencies, there's no convincing reasoning based on real reliable sources or evidence in these multiple discussion threads, that changes basic facts or proves that Bitcoin is somehow preferable to a Paypal donation.

However there is plenty of unfactual chaff and confusion, which may be effective at gaming the vote outcome here. This means that the number of transactions within a block has no impact on its energy expenditure: for a given difficulty level, a full block containing thousands of transactions has the same electricity footprint as an empty block with no transactions. The cost per transaction has increased significantly over time, due to the value of bitcoins increasing disproportionate to the number of transactions.

Some point to this as an inherent inefficiency in Bitcoin, and others expect that market forces will balance this over time at the agreed market value of a Bitcoin transaction. The analysis provides insights for identifying potential focus areas, plus a misalignment between the guiding SoS [system of systems] level organization, the Bitcoin Foundation, and their support for an even playing field of competition between cryptocurrencies, in the same way that Bitcoin wants to compete against traditional options.

There is potential to capitalize on differing approaches in deflationary or inflationary coin supplies to provide robustness to the overarching goals outlined in the original architecture specification. These decisions are likely to not be in line with what is the best for Bitcoin or the speculative investors, but the entire system of systems could be better off for it. First, the use of transactions as the driver of future Bitcoin emissions is questionable, given the tenuous correlation between transactions and mining energy use.

It is well established that energy use is driven by the computational difficulty of the blocks mined whereas the number of transactions per block can evolve for example, via SegWit with no direct effect on block mining difficulty. The authors themselves calculate Bitcoin energy use and emissions in on the basis of block difficulty, not the number of transactions. Without explanation, the authors switch to transactions as the driver for projecting future emissions, undermining their methodological consistency and the integrity of their projections.

The noise about proof of work's environmental impact originates from the Digiconomist, which is authored by an employee of the Dutch Central Bank. In case you don't see the obvious bias conflict, the main idea behind Bitcoin is that it is a decentralized alternative to central banking.

The Digiconomist is a propaganda outlet of the central bank system that is the dominant economic paradigm today that got us into the over-consuming environmental mess that we find ourselves today. They completely mislead the public as to how Bitcoin works: the notion of a "per transaction cost" is nonsensical, because one transaction on the blockchain could represent millions of real-world transactions, through transaction batching and layer 2 payment networks.

There is no way of knowing the true number of transactions. Bitcoin is the solution, not the problem -- fix the money, fix the world. The environmental FUD levelled at Bitcoin and Proof of Work has been debunked over and over again by those who actually understand Bitcoin and it's integration with the global energy markets.

Bitcoin is a net positive for the environment, subsidizing the deployment of renewable energy production and directly reducing GHG emissions in the oilfield. As civilization progresses, we need to and will produce more -- not less -- energy. Bitcoin will play a vital role in subsiding sustainable energy rollout in global energy markets, in spite of the FUD being propagated by the incumbent financial powers and the misinformed who believe their lies.

We believe concerns about the high-energy intensity of Bitcoin mining are overstated, and the technology can play a less-acknowledged but important role in promoting financial inclusion. Bitcoin's carbon emissions are low compared to its market value, implying that Bitcoin is characterized by a lower carbon intensity than the average asset in the portfolio. Thus, an isolated focus on Bitcoin's absolute carbon emissions can be highly misleading from an investment and portfolio perspective Importantly, in contrast to the widespread negative perception of Bitcoin in the climate change debate, we also find that Bitcoin investments can be less carbon intensive than standard equity investments.

The addition of Bitcoin to a diversified equity portfolio can thus lower the portfolio's aggregate carbon footprint. With bitcoin it is at least theoretically possible to perform monetary transactions using exclusively FLOSS software, without the use of a centralized proprietary infrastructure. The proposal conflates the existence of Bitcoin to merely using it. The proposal does not demonstrate that dropping acceptance of Bitcoin or other cryptocurrency will actually have an effect.

As a technical matter, there is no direct relationship between making a Bitcoin transaction and energy usage that's significantly more than the domestic banking system. Besides being a purely subjective point that doesn't belong here, you risk your reputation by taking damaging political stances like this. For these reasons, the RfC should be revised and resubmitted. Point 2 needs evidence that the call to action will accomplish the stated goal; points 1 and 3 should be withdrawn.

Please see the reliable sources section below, rather than just disputing the one source. Plenty of high quality sources publish the fact that Bitcoin is a significant contributor to climate change and unethical energy waste, at the level of disrupting economies of entire countries. Advocating that the Wikimedia Foundation must continue to accept the use of Bitcoin, and tacitly supporting its use, should at least have the same quality of reliable sources to justify that decision, rather than repeating and relying on PR spin and rhetoric from lobbyists, which most of the input on that side of the discussion so far seems to boil down to.

We further calculate that the resulting annual carbon emissions range between The magnitude of these carbon emissions, combined with the risk of collusion and concerns about control over the monetary system, might justify regulatory intervention to protect individuals from themselves and others from their actions.

We determine the annual electricity consumption of Bitcoin, as of November , to be This means that the emissions produced by Bitcoin sit between the levels produced by the nations of Jordan and Sri Lanka, which is comparable to the level of Kansas City. In the light of the disruption resulting from single purpose accounts dropping in to vote and add to discussions, but these boiling down to rhetoric which on examination has zero reliable sources, here are a few more reliably independent sources and correctly peer reviewed publications that could be quoted to support various viewpoints and may help go beyond PR spin from "business centres", website FAQs or "opinion" pieces being reprinted for catchy headlines.

Maybe others voting in this discussion have high quality sources not just opinion pieces from those paid to lobby for bitcoin and peer reviewed sources they can recommend:. But the global chip shortage means semiconductor foundries like Taiwan Semiconductor Manufacturing Co.

They are also cautious about adding new capacity given how finicky crypto demand has proven to be. It is my understanding that the Wikimedia Movement wants to be a global movement. Thus I believe the fact that Bitcoin is legal tender and therefor an official currency in El Salvador should be taken into consideration when making a decision. I could not find that Wikimedia Foundation has active chapters in El Salvador. However if we did have a chapter there it is my understanding that we would legally be required to accept Bitcoin in El Salvador.

Also while looking at that page I wonder weather Wikimedia Foundation accepts all other official currencies of sovereign Nations or are there some currencies which are not accepted at all? If so, why not? Currently, Accessing or sponsoring Wikipedia, or international non-profit organizations in general, is not exactly legal in a number of countries. Cryptocurrency is a way of contribution that allow individuals from those countries to made donation, without having to worry about their own personal information on the donation being revealed to the national government through the national banking system, and thus is a safer and lower risk option for them.

Not everyone living in such countries are in total poverty. Eliminating cryptocurrency as a mean of donation would increase the personal risk of donors coming from individuals in those countries, and this in my opinion is extremely undesirable. Identity of the donor will still be retained by the payment processor, however that payment processor is most likely in a different country from those aforementioned, and thus wouldn't have as much risk of donor personal information being revealed to relevant national governments.

C talk , 17 January UTC [ reply ]. Reading this thread is frustrating. I am one of those "small number of people" who make donations by crypto. I do not have any access to banking services. But in many parts of the world it is a powerful tool of financial inclusion and also the most economical and reliable way to send money. WMF could demonstrate its environmental commitment by encouraging newer crypto technologies such as Nano XNO while discouraging high-energy and high-fees BTC and ETH, which aren't really suited for donating small amounts anyway.

If you need further proof that PoS cryptocurrencies should at least be considered, here's an extract from an article in today's Financial Times archive :.

The difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. The rate is recalculated every 2, blocks to a value such that the previous 2, blocks would have been generated in exactly one fortnight two weeks had everyone been mining at this difficulty.

This is expected yield, on average, one block every ten minutes. As more miners join, the rate of block creation increases.
