Solve math problems for bitcoins

Bitcoin successfully halved its mining reward—from This system will continue until around These fees ensure that miners still have the incentive to mine and keep the network going. The idea is that competition for these fees will cause them to remain low after halvings are finished. These halvings reduce the rate at which new coins are created and, thus, lower the available supply.

This can cause some implications for investors, as other assets with low supply—like gold—can have high demand and push prices higher. At this rate of halving, the total number of bitcoin in circulation will reach a limit of 21 million, making the currency entirely finite and potentially more valuable over time. In order for bitcoin miners to actually earn bitcoin from verifying transactions, two things have to occur. First, they must verify one megabyte MB worth of transactions, which can theoretically be as small as one transaction but are more often several thousand, depending on how much data each transaction stores.

Second, in order to add a block of transactions to the blockchain, miners must solve a complex computational math problem, also called a "proof of work. In other words, it's a gamble. The difficulty level of the most recent block as of August is more than 16 trillion.

That is, the chance of a computer producing a hash below the target is 1 in 16 trillion. To put that in perspective, you are about 44, times more likely to win the Powerball jackpot with a single lottery ticket than you are to pick the correct hash on a single try. Fortunately, mining computer systems spit out many hash possibilities.

Nonetheless, mining for bitcoin requires massive amounts of energy and sophisticated computing operations. The difficulty level is adjusted every blocks, or roughly every 2 weeks, with the goal of keeping rates of mining constant. The opposite is also true.

If computational power is taken off of the network, the difficulty adjusts downward to make mining easier. Say I tell three friends that I'm thinking of a number between 1 and , and I write that number on a piece of paper and seal it in an envelope. My friends don't have to guess the exact number, they just have to be the first person to guess any number that is less than or equal to the number I am thinking of.

And there is no limit to how many guesses they get. Let's say I'm thinking of the number There is no 'extra credit' for Friend B, even though B's answer was closer to the target answer of 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.

The difference is best explained by the following beautiful quotation from Langlands :. When God created the world, and therefore mathematics, he called upon the Devil for help. He instructed the Devil that there were certain principles, presumably simple, by which the Devil must abide in carrying out his task but that apart from them, he had free rein. Both Chevalley and Harish-Chandra were, I believe, persuaded that their vocation as mathematicians was to reveal those principles that God had declared inviolable, at least those of mathematics for they were the source of its beauty and its truths.

They certainly strived to achieve this. If I had the courage to broach in this paper genuine aesthetic questions, I would try to address the implications of their standpoint. Question Which kind of mathematical problems do you have to solve in order to mine bitcoins? Let me clarify that I'm not interested in mining, only in knowing whether the problems are divine or devilish. Bitcoin mining is based on hash functions.

Specifically the SHA hash function, which maps arbitrary bit strings to bit outputs in such a way that nobody knows how to find a collision two inputs with the same output , although the pigeonhole principle implies collisions exist. Bitcoin mining doesn't involve finding collisions, which would be way too hard. Instead, one has to find inputs that lead to outputs with special properties, namely a lot of consecutive zeros.

This is a scaled-down version of inverting the hash function. Of course there's no proof that any of this is actually computationally difficult, and some earlier hash functions have turned out to be weaker than expected for example, MD5 and SHA-1 , but it certainly seems to be. SHA is not a nice or simple function - it was designed to be hard to analyze - so I'd say this is a devilish problem. Another way to earn bitcoin is not to mine them, but to have them wired to you from other bitcoin accounts.

So if you solve the discrete logarithm problem in an elliptic curve for bitcoin this is the curve Secpk1 , then you potentially can earn many bitcoins illegally of course Personally I find this problem much more beautiful than finding lot of zeroes in the SHA hash function. So you need to know what hash functions are to understand the problem, don't worry its easy and anyone can understand it because solving this puzzle doesn't require intelligence but patience.

A hash function is just a function that when you give it an input of X byte size data, image, text, anything Hash functions have some properties and one of them is when you give it different input it always produces a completely different output, so if change only one bit in that 5gb video the output of the hash function is going to change radically. So in bitcoin, miners keeps listening for transactions and from these transaction they create a block but in order for all participating nodes to accept this block they have to change a specified region in the block and see if the resulting output starts with x number of zero's because in computers everything is ones and zeroes.

If the result is not correct output string does not start with 30 zeroes they change that region again and check the output, until they finally find the right combination of bits in that region that when you pass that block to the hash function it will produce a string that starts with 30 zeroes.

Mining rewards provide this incentive. Miners are essentially putting a notary stamp on a batch of transactions. That's all they are needed for. But how do you prevent from having a corrupt notary? Bitcoin does this by having tens of thousands of potential notaries and one of them will happen to be the lucky one that gets to do the stamp.

The lucky one is the one who happens to solve the problem. All the potential notaries try to solve the puzzle over and over, but it will take about ten minutes for one to become successful. Others will see the solution, and if it is valid, will continue on to the next puzzle. This builds a chain of batches. So to go back in history to change the batches of transactions requires having to redo all the problem solving attempts that occurred previously.

The further back you want to go, the more problem solving work you need to perform. So the problem being solved is a system that makes it enormously expensive to change history. That's the job that miners are paid to provide. No, no-one is paying for the solutions to the math problems. In fact, they are only math problems in the same sense that watching a Youtube video is doing a computation. Miners are checking transactions of other users. The Bitcoin protocol is built in such a way that this process sometimes creates new bitcoins.

The creation of new bitcoins is also regulated by the protocol - only 21 million can be created, and the last Bitcoin will be created around The creation of coins is distinct from the value of the coins, which come from their usefulness, supply and demand. There is another cryptocurrency, Primecoin XPM , which uses calculation of prime numbers in the "proof of work" process of the currency.

These prime numbers do have potential scientific value, but the value of Primecoin is not linked to the value of the prime numbers. The prime numbers are publicly available, and value again comes from supply, demand and usefulness. The goal is that the computation involved in "proof of work", which must be done anyway, should have a side-benefit. Mining essentially tries to brute force decrypt an encryption. This is not so much a complex mathematical problem as rather systematically trying a multitude of potential solutions until one fits the current prerequisites context and difficulty.

The purpose of mining is to validate the transactions of the network. The more computational effort is applied to mining, the more resilient is the network against attacks. Therefore the Bitcoin protocol has been designed to dispense rewards among the miners to incentivize behavior that is beneficial to the network — whoever finds the winning solution is allowed to transmit a number of newly created coins to an address of his choice.
