The Of Bitcoin Mining Power

If you are mining Bitcoin, you do not need to calculate the entire value of the 64-digit number (the hash). I repeat: You do not need to figure the entire value of a hash.

Remember that ELI5 analogy, in which I wrote the number 19 on a piece of newspaper and put it in a sealed envelope

In Bitcoin mining terms, that metaphorical undisclosed number in the envelope is known as the objective hash.

What miners are doing with those huge computers and dozens of cooling fans is guessing in the hash. Miners make these guesses by randomly generating as many"nonces" as possible, as quickly as possible. A nonce is short for"number only used once," and also the nonce is the secret to generating these 64-bit hexadecimal numbers I keep talking about.

The first miner whose nonce generates a hash that is less than or equivalent to the target hash is given credit for completing that block, and is given the spoils of 12.5 BTC. .

In theory you can Attain the Exact Same aim by rolling a 16-sided die 64 times to Reach random numbers, but why on earth do you want to do that

The screenshot below, taken by the website Blockchain.info, might enable you to put all of this information together in a glance. You are looking at a list of everything that happened when obstruct 490163 was mined. The nonce that generated the "winning" hash was 731511405. The target hash is shown on the top.

As you see here, their contribution to the Bitcoin community is that they confirmed 1768 transactions for this block. If you really want to find all 1768 of those transactions for this block, go to this webpage and scroll down to the heading"Transactions." .

There's no minimum target, but there's a maximum target determined by the Bitcoin Protocol. No goal can be greater than this number:

Here are some examples of randomized hashes and the criteria for whether they will lead to success for your miner:

You'd need to find a speedy mining rig , more realistically, join a mining pool--a bunch of miners who combine their computing power and divide the mined bitcoin. Mining pools are somewhat similar to those Powerball clubs whose members buy lottery tickets en masse and consent to discuss any winnings. A disproportionately large number of cubes are mined by pools rather than by individual miners. .

In other words, it's literally only a numbers game.  You cannot guess the pattern or make a prediction based on preceding goal hashes. The difficulty level of the most recent block at the time of writing is 2,874,674,234,416, i.e. the chance of any given nonce producing a hash below the target is just 1 in 2,874,674,234,416--less than 1 in 2 trillion. .

The aforementioned website Cryptocompare delivers a helpful calculator which allows you to plug in numbers like your hash speed, power costs etc. to estimate the costs and benefits.

Mining rewards are paid into the miner who discovers a solution to the puzzle first, and the probability that a participant is going to be the one to discover the solution is equivalent to the portion of the entire mining power on the network.  Participants with a small percentage of their mining power stand a very small chance of discovering the next block on their own.  For instance, a mining card that one could buy to get a few thousand dollars would represent less than 0.001percent of their network's mining power.  With such a tiny chance at finding the next block, it could be a long time before that miner finds a block, and the problem going up makes things even worse.  The miner may never recover their investment.  The answer to this problem is mining pools.  Mining pools are run by third parties and coordinate groups of miners.  By working together in a swimming pool and sharing the payouts amongst participants, miners can get more get a steady flow of bitcoin starting the afternoon that they activate their miner.  Statistics on a few of the mining pools can be seen on Blockchain.info. .

Sure. As discussed, the easiest way to acquire Bitcoin is to purchase it on an exchange such as Coinbase.com. Alternately, you can always leverage the"pickaxe strategy". This relies on the old saw that during the 1848 California gold rush, the smart investment was not to pan for gold, but rather to create the pickaxes taken for mining.

In a crypto context, the pickaxe equivalent are a company that manufactures equpiment used for Bitcoin mining. You can look into companies that make ASICs miners or GPU miners. .
