How Does Bitcoin Mining Work?

NOTE: the following are taken largely from Puppet's Cloud Mining reddit post, which is a great supplement to this post. If you have purchased options for the right to some amount of hashing power, there is no reason why you shouldn't be able to direct that hashing power to any pool that you want. There are only a handful of ASIC manufacturers who could service a large scale mining operation with hardware. Any cloud mining operation would not only allow an ASIC manufacturer to disclose a large ASIC purchase, but they'd also want them to do so to prove they are serious.

So far, no cloud mining operation we are aware of has has an ASIC manufacturer acknowledge they are selling hardware to a cloud mining company. Bitcoin mining is very competitive and has incredibly thin margins. There would be no way to mine profitably if they were paying not only you, but also the person who referred you.

If there is no way to the know idenntity of the cloud mining operation, there is no way to hold them accountable if they run with the money. It also makes it harder to catch the person who stole your money. WARNING: Just because a cloud mining website boasts a famous person as an investor or advisor does not mean that person is actually investing or advising. Anyone can throw up a picture of Elon Musk on their site. The real proof is if Elon Musk himself says in a news clip that he is a founder.

Investments should never be a one-way transaction. If you can easily give the cloud miner money, but there is no obvious way to sell your position and get it back, then that is a good indication you will never get your money back.

Any investment that guarantees profits is a scam. If the cloud miner has so far made good on delivering its guarantees, it is because they are using funds from new investors to pay off old ones and appear solvent. Ponzi schemes work this way. Eventually, they are going to run with the money, but you never know when it will happen. The other point to consider is: if a miner could guarantee profits, why would they sell that right to you?

Why wouldn't they take teh guaranteed profits for themselves? If the amount of shares for sale in the cloud mining operation appear infinite, then they are definitely running a scam. No miner has an unlimited amount of hashing power. Most cloud mining companies accept Bitcoin, PayPal, and credit cards.

If a cloud mining company accepts bitcoins then there is a good chance it is a scam. This is because Bitcoin payments cannot be reversed. Once the scam company receives your bitcoin payment you have no way to get your coins back.

Any company offering free trials, especially if they require payment information, is most likely a scam. Our guide on the best bitcoin wallets will help you pick one. Read it here! Cloud mining means a host company owns Bitcoin mining hardware and runs it at a professional mining facility. You pay the company and rent out some of the hardware. Based on the amount of hash power you rent, you will earn a share of payments from the cloud mining company for any revenue generated by the hash power you purchased.

In most cases, though, there is no mining facility or hardware. There is just a guy taking your money and paying part of it to someone who signed up before you did. Eventually he runs away with the money, and you are left with nothing.

Mining software is something you download on your computer. It is required when you OWN mining hardware. Software connects your hardware to the internet so that it can make hashes and communicate with the network. Just find an exchange in your country and buy some bitcoins. If you're still a bit confused about what Bitcoin mining is, that's okay. That's one reason I built this site, to make it easier to understand! One common question people ask is if they can just invest in the mining companies instead of trying to mine themselves.

The answer is: yes, you absolutely can. And you wouldn't be the only ones investing in these companies. Fidelity, Vanguard, and Charles Schwab Funds have all been buying these stocks en masse.

So when Jamie Dimon, CEO of Chase, denigrates Bitcoin , just remember that many of his friends at the big banks are loading up on these stocks themselves. Disclaimer: Buy Bitcoin Worldwide is not offering, promoting, or encouraging the purchase, sale, or trade of any security or commodity.

Bitcoin mining seems crazy! Computers mining for virtual coins? Is Bitcoin mining just free money? Well, it's much, much more than that! If you want the full explanation on Bitcoin mining, keep reading Jordan Tuwiner Last updated December 1, Chapter 1 What is Bitcoin Mining?

Bitcoin mining is the backbone of the Bitcoin network. Miners provide security and confirm Bitcoin transactions. Without Bitcoin miners, the network would be attacked and dysfunctional. Bitcoin mining is done by specialized computers. The role of miners is to secure the network and to process every Bitcoin transaction. For this service, miners are rewarded with newly-created Bitcoins and transaction fees. What is Bitcoin mining actually doing? Miners are securing the network and confirming Bitcoin transactions.

Miners are paid rewards for their service every 10 minutes in the form of new bitcoins. What is Bitcoin Mining Actually Doing? What is the point of Bitcoin mining? This is something we're asked everyday! There are many aspects and functions of Bitcoin mining and we'll go over them here.

They are: Issuance of new bitcoins Confirming transactions Security Mining Is Used to Issue new Bitcoins Traditional currencies--like the dollar or euro--are issued by central banks. Bitcoin is different. With Bitcoin, miners are rewarded new bitcoins every 10 minutes. Miners Confirm Transactions Miners include transactions sent on the Bitcoin network in their blocks. A transaction can only be considered secure and complete once it is included in a block.

More confirmations are better for larger payments. Here is a visual so you have a better idea: 0 Payments with 0 confirmations can still be reversed! Wait for at least one. Most exchanges require 3 confirmations for deposits. Six is standard for most transactions to be considered secure.

Chapter 3 How to Mine Bitcoins. Actually want to try mining bitcoins? Most Bitcoin mining is done in large warehouses where there is cheap electricity.

To be real: Most people should NOT mine bitcoins today. Most Bitcoin mining is specialized and the warehouses look something like this: Source ieee. Step 1: Get Bitcoin Wallet When earning bitcoins from mining, they go directly into a Bitcoin wallet. You can't mine without a wallet. Popular Exchanges. Coinbase High liquidity and buying limits Easy way for newcomers to get bitcoins "Instant Buy" option available with debit card.

Interestingly, the market price of bitcoin has, throughout its history, tended to correspond closely to the reduction of new coins entered into circulation. This lowering inflation rate increased scarcity and historically the price has risen with it. Although early on in Bitcoin's history individuals may have been able to compete for blocks with a regular at-home computer, this is no longer the case. The reason for this is that the difficulty of mining Bitcoin changes over time.

In order to ensure the smooth functioning of the blockchain and its ability to process and verify transactions, the Bitcoin network aims to have one block produced every 10 minutes or so. However, if there are one million mining rigs competing to solve the hash problem, they'll likely reach a solution faster than a scenario in which 10 mining rigs are working on the same problem.

For that reason, Bitcoin is designed to evaluate and adjust the difficulty of mining every 2, blocks, or roughly every two weeks. When there is more computing power collectively working to mine for Bitcoin, the difficulty level of mining increases in order to keep block production at a stable rate. Less computing power means the difficulty level decreases. To get a sense of just how much computing power is involved, when Bitcoin launched in the initial difficulty level was one. As of Nov.

All of this is to say that, in order to mine competitively, miners must now invest in powerful computer equipment like a GPU graphics processing unit or, more realistically, an application-specific integrated circuit ASIC. The photo below is a makeshift, home-made mining machine. The graphics cards are those rectangular blocks with whirring fans.

Note the sandwich twist-ties holding the graphics cards to the metal pole. This is probably not the most efficient way to mine, and as you can guess, many miners are in it as much for the fun and challenge as for the money. The ins and outs of bitcoin mining can be difficult to understand as is. 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. In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day, there can only be one winning answer.

Typically, it is the miner who has done the most work or, in other words, the one that verifies the most transactions. The losing block then becomes an " orphan block. Miners who successfully solve the hash problem but who haven't verified the most transactions are not rewarded with bitcoin. Well, here is an example of such a number:. The number above has 64 digits. Easy enough to understand so far. As you probably noticed, that number consists not just of numbers, but also letters of the alphabet.

Why is that? To understand what these letters are doing in the middle of numbers, let's unpack the word "hexadecimal. As you know, we use the "decimal" system, which means it is base This, in turn, means that every digit of a multi-digit number has 10 possibilities, zero through nine. In a hexadecimal system, each digit has 16 possibilities.

But our numeric system only offers 10 ways of representing numbers zero through nine. That's why you have to stick letters in, specifically letters a, b, c, d, e, and f.

If you are mining bitcoin, you do not need to calculate the total value of that digit number the hash. I repeat: You do not need to calculate the total value of a hash.

Remember that ELI5 analogy, where I wrote the number 19 on a piece of paper and put it in a sealed envelope? In bitcoin mining terms, that metaphorical undisclosed number in the envelope is called the target hash. What miners are doing with those huge computers and dozens of cooling fans is guessing at the target hash. A nonce is short for "number only used once," and the nonce is the key to generating these bit hexadecimal numbers I keep talking about.

In Bitcoin mining, a nonce is 32 bits in size—much smaller than the hash, which is bits. In theory, you could achieve the same goal by rolling a sided die 64 times to arrive at random numbers, but why on earth would you want to do that? The screenshot below, taken from the site Blockchain.

You are looking at a summary of everything that happened when block was mined. The nonce that generated the "winning" hash was The target hash is shown on top. The term "Relayed by Antpool" refers to the fact that this particular block was completed by AntPool, one of the more successful mining pools more about mining pools below. As you see here, their contribution to the Bitcoin community is that they confirmed transactions for this block.

If you really want to see all of those transactions for this block, go to this page and scroll down to the heading "Transactions. All target hashes begin with zeros—at least eight zeros and up to 63 zeros. There is no minimum target, but there is a maximum target set by the Bitcoin Protocol. No target can be greater than this number:.

Here are some examples of randomized hashes and the criteria for whether they will lead to success for the miner:. Note: These are made-up hashes. You'd have to get a fast mining rig, or, more realistically, join a mining pool—a group of coin miners who combine their computing power and split the mined bitcoin.

Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.
