Best Way To Mine Bitcoins - Allow Errors!

An anonymous reader writes: A recent paper from the University of Illinois at Urbana-Champaign shows that bitcoin mining profits can be increased considerably if mining hardware is allowed to produce occasional errors. The research shows that mining hardware that allows occasional errors ("approximate mining") can run much faster and take up less area than a conventional miner. Furthermore, the errors that are produced by the miner do no corrupt the blockchain since such errors are easily detected and discarded by the bitcoin network. Mining profits can increase by over 30%.

      I don't believe my premise is wrong, but I may have not made it all clear due to brevity. Of course reality is more complex than a few sentences in a slashdot comment; if it were this simple we'd all be economy experts. Let me try to clear things up.

      Inflation can be due to a government printing money because it CAN'T borrow enough.

      The government doesn't print money. Well, it does, but not nearly enough to matter, and in order to print it, the money has to be created first via a borrowing event. Look up how that all works.

      When the news says the government is 'creating money' they really mean they are borrowing it. The US government has no direct control over the money supply, that's all handled by the Federal Reserve, which despite having "Federal" in the name is actually a private entity. Really.

      The US government borrowed tons of money in 2015, and inflation was way below average.

      The correlation is not immediately 1:1. It takes some time for the created money to get into the system. That said, the industries where the government is spending the money tend to be impacted first - so if you want to see what the impacts are, look at those areas. Education and Healthcare have been focuses recently, look at the inflation numbers in those fields.

      Education is a great example; we tend to all agree that education costs too much (despite it becoming easier to actually distribute information) - it's due to dollars in that area simply not being worth the same amount as dollars spent elsewhere. This is thanks to government funding the schools directly, subsidizing tuition under the covers, and making loans very accessible. Money is easier to come by, so it's not worth as much.

      I'm all for helping people- but the government programs to make college more accessible are making it cost more and hurting competition, and in the end hurting those we're trying to help. Schools don't need to get more efficient or produce better graduates, they have no impetus to. In some cases (such as government assistance to colleges based on square footage) schools actually have good reason to retain and expand old practices, which the modern student gets to help pay for, but gets limited benefit from.

      "Inflation" in the education space has been miles higher than the overall "inflation" number that gets published. That's the place to look for a short-term study on government spending. Similar stories can be found in healthcare.

      Whoa, that's absurdly incorrect. Appreciation != inflation.

      I didn't say due to appreciation, I said due to inflation. There's no additional value in this mythical house.

      Let's say it another way - 30 years ago you took out a (for simplicity, 0%) loan for $100k. You still haven't paid it back today, but today it's much easier to pay it back because $100k is a lot less money than it used to be. The loan, like the house, hasn't appreciated. The only thing that's changed is the value of the dollar, effectively shrinking your debt without you doing anything to shrink it. Even if you're paying interest on the loan, if you got a good loan, your interest rate is less than inflation. Same effect but slower. As such, inflation helps (or at least *can help*) the people who can get good loans or own things, and just make things cost more for those who can't.

      How is this a whole lot different from normal currency? I'm not sure I understand this.

      For a long time, gold was used as a currency. Arguably it still serves that purpose. More gold can be brought into circulation by mining it. However, as more mining occurs, it becomes more difficult and expensive to access gold deposits. That's a fairly accurate description of bitcoins, too. For a long time, into the 20th century, the US Dollar and other currencies were backed with gold. Old paper money from the US has text on it indicating it can be exchanged for gold of equivalent value. We don't do that anymore, instead using something called the fiat system. Effectively the US dollar has value because we say it does. Money is transferred electronically with great frequency, and that's every bit as virtual as bitcoins. In principle, it can always be exchanged for a one to one value for the equivalent physical currency. Nonetheless, it really isn't a whole lot different in any of those respects.

      Also, let's not pretend that printing and minting currency is clean and without waste. And mining gold certainly isn't a particularly clean process. I don't think those criticisms are valid at all.

      Arguably bitcoins have an advantage over some other modern currencies. There's a fixed maximum number of bitcoins that can be in circulation. This along with the decentralized nature makes it resistant to creation of money via the printing press (or the virtual equivalent thereof). That makes it much more difficult for a government to devalue your currency in that manner to pay their debts.

    I hope that no one believes that Bitcoin has no value. It has whatever value is assigned to it by the people willing to use it.

    However, much could be said about fiat currencies especially if they are poorly managed. It is usually just that a fiat currency is managed, and closely watched and protected. That has both positive and negative effects.

    You missed one of the largest problems with Bitcoin: It was designed to be deflationary. Most fiat currencies are designed to be slightly inflationary, which encourages people to spend or invest it (the economy, in a nutshell), rather than hoard it or invest in it on speculation that it might be worth more in the future. Unlike investing in a business, precious metal, or commodity, when you buy Bitcoin you're not putting your faith in peoples' ability to turn a profit, the labor and costs involved in mining and extracting a rare element, or something with intrinsic value. You're simply buying into a cryptocurrency modeled after a pyramid scheme.

    To truly picture what's wrong with Bitcoin, think of a new iPhone release. Yeah, some of the people buying them are speculating that they'll be able to sell them for a profit on eBay. Perhaps some of the buyers on eBay are speculating they can re-sell the phones in their bodega cell phone shops. But ultimately, at the end of the line are people who just want to actually buy an iPhone to use it.

    Bitcoin's utility is limited by the hassle of exchanging it to and from fiat, its unstable value, and extremely limited merchant acceptance. It's kinda like paying a fee to have someone hold your wallet and randomly add or remove some of your money, and most of the time tell you "no" when you ask if you can spend your money at a merchant.

  36. Better solution: eliminate the programs altogether by Anonymous Coward · · Score: 0

    What we should do is encourage the economy and people to become more efficient and competitive. Right now the law creates a lot of monopolies/duopolies/etc (from internet access and cable television service to government schooling). Some of that does involve letting industries and companies go out of business (banks) when more competitive solutions come along (or f**** ups happen). What we should do is eliminate the programs altogether or severely curtail them and then open the markets up to competition. Unfortunately some of the laws which created and/or ensure the monopolies/duopolies need to go in the other direction now as otherwise no newcomers can afford to enter the market. For instance cable providers often have a monopoly position because towns gave them these monopolies in exchange for rolling out service. What we need to do now is create programs to incentives competitors enter these markets. That might be a good thing to have across the board actually- incentivizing startups and companies to enter new markets. Maybe a reduced tax rate or elimination of taxes for a certain amount of time for new entrances to the market.

    We need to eliminate not just corporate welfare or social programs even- but all the programs. We should all but eliminate funding of the public education system through taxes for example. We should open up the boarder. That's OK if we're actually creating a competitive situation for Americans. We should eliminate copyright except for where it is actually in the public's interest (ie to ensure competition in the case of free software, that is where the sources are publicly released under copyleft licenses).

    We don't need taxpayers to fund the majority of public school students educations to ensure all students receive a good education (ie I'm against voucher programs- we shouldn't be funding private anything with tax dollars). What we need to do is eliminate welfare programs for the middle and upper classes to send there children to school and only lend sufficient amounts of money to cover students educational costs whom can't afford it otherwise. This would both guarantee students get a good education, reduce the cost of education (as it creates competitiveness in the market for schools, etc) and eliminate excess taxation of the masses such that they can't afford to cover there children's education.

    Rather than funding health care with public tax dollars or requiring everybody to obtain insurance is we could create a multitude of non-profit health insurance entities. We should eliminate drivers licenses, registration, and auto-insurance, as unnecessary tax generating programs that have no real public value (NH does just find without requiring auto-insurance, and registration is merely a tax generating program, drivers licenses aren't needed for an arrest either if someone is driving dangerously). and reduce or eliminate state and federal police forces.

Utility != value. After all, I may very well exchange something of value that I own for something useless to me, as long as I know I can exchange that useless thing for something else that does have utility to me. Then you may say: "well, but if you can exchange that, then it's not useless to you", to which I'll reply that, by that standard, everything has significant value to me as long as someone is willing to exchange it for something else I want. But that would make it clear that the value of that "thing" is neither intrinsic to the thing itself, nor decided by my own judgement, but is instead decided by the judgement of other people who may be interested in it. Now change places with one of those people, and you'll reach the same conclusion, thereby realizing that this subjective interpretation doesn't really explain value at all; it only describes the market (accurately).
